Patent Administration:
Current Issues and Possibilities for Reform
The United States Patent and Trademark Office (“USPTO”) examines patent
applications to determine whether the subject matter claimed within those
applications is sufficiently inventive to merit the award of a patent. The environment
in which patent examination occurs has become increasingly challenging. The
USPTO is facing an escalating rate of patent application filings as well as
applications of increasing technical complexity. Other potential concerns include
budgetary constraints and the retention of personnel with appropriate technical and
legal qualifications to perform patent examination tasks.
Out of recognition of these challenges, the administrative procedures through
which the USPTO conducts patent examination have been subject to renewed public
dialogue and congressional interest. Legislation pending before the 107th Congress
would introduce reforms to patent administration. Should Congress further consider
this issue, USPTO practices may be reviewed with an eye towards their capability for
maintaining acceptable levels of patent quality within current resource constraints.
Congress may conclude that current USPTO practices provide an appropriate
level of scrutiny of patent applications. In the event that reform is contemplated,
however, widely circulated proposals and the practices of other leading patent-
granting agencies, notably the European Patent Office (“EPO”) and the Japanese
Patent Office (“JPO”), suggest the latest thinking on patent administration reform.
One set of reform proposals involves augmenting the responsibilities of patent
applicants. Although inventors who seek patent protection are responsible for
preparing an application, they are currently not required to perform a search of public
domain information to determine if their technology is sufficiently inventive to merit
a patent. Some proposals would mandate that applicants perform such a search, or
at least state whether they have done so. Others would require applicants to
distinguish more carefully their inventions from the state of the art.
A second group of reform proposals involves an assessment of the contributions
members of the general public might make within an optimal patent examination
regime. Interested third parties might be invited to comment upon pending patent
applications. Alternatively, they could invoke administrative patent revocation
proceedings at the USPTO known as “oppositions.”
Finally, Congress may wish to consider more general workload reduction
proposals. Currently the USPTO automatically subjects each submitted application
to a detailed substantive examination. Other possibilities include deferral of
examination or the automatic registration of every submitted application. The
USPTO might also rely upon the results of foreign patent offices in reaching its own
patentability decisions.

Patent Administration:
Current Issues and Possibilities for Reform
The administrative practices of the United States Patent and Trademark Office
(“USPTO”) have been the subject of renewed interest. Congressional hearings,1
academic inquiry,2 and public dialogue3 alike have considered the rigor of review
performed by USPTO examiners when approving patent applications. Legislation
introduced before the 107th Congress would also address this issue.4
Growing interest in sound patent administration has tracked the increase in
public attention to the patent system as a whole.5 More particularly, discussion
concerning patent administration has also been inspired by accounts suggesting that
the USPTO has become more lenient in awarding patents. Some commentators
believe that an increasing number of patents issue that lay claim to knowledge that
had already been in public use.6 This issue of “patent quality” potentially impacts
industries as diverse as biotechnology, business methods, pharmaceuticals and
software.7 It appears particularly important to those innovative individuals and
enterprises with which the patent system has traditionally been associated, and that
some believe play an important role in driving the U.S. economy.8
Concern over patent administration is not confined to the United States. The
two other leading patent-issuing agencies, the European Patent Office (“EPO”) and

Given the extensive participation of U.S. industry in both of these foreign intellectual
property regimes,10 developments at the EPO and JPO are of interest domestically.
This report discusses current issues in patent administration and considers
possibilities for reform. It begins with an overview of fundamental aspects of patent
administration. It then considers contemporary challenges faced by the USPTO as
well as the potential effect of these challenges upon innovation. The report then
introduces and analyzes recent reforms undertaken or proposed by the USPTO, EPO
or JPO. This report concludes with brief observations on patent administration
Patent Administration Fundamentals
Patent rights do not come into being automatically. Inventors must prepare and
submit applications to a federal government agency known as the “U.S. Patent and11
Trademark Office,” or USPTO, if they wish to obtain patent protection. USPTO
officials known as examiners then assess whether the application merits the award1213
of a patent. The patent acquisition process is commonly known as “prosecution.”
In deciding whether to approve a patent application, a USPTO examiner will
consider whether the submitted application fully discloses and distinctly claims the14
invention. In addition, the application must disclose the “best mode,” or preferred
way, that the applicant knows to practice the invention.15 The examiner will also
determine whether the invention itself fulfills certain substantive standards set by the
patent statute. To be patentable, an invention must be useful, novel and nonobvious.
The requirement of usefulness, or utility, is satisfied if the invention is operable and
provides a tangible benefit.16 To be judged novel, the invention must not be fully
anticipated by a prior patent, publication or other knowledge within the public

domain.17 A nonobvious invention must not have been readily within the ordinary
skills of a competent artisan at the time the invention was made.18
If the USPTO allows the patent to issue, the patent proprietor obtains the right
to exclude others from making, using, selling, offering to sell or importing into the
United States the patented invention.19 Patent title therefore provides inventors with
limited periods of exclusivity in which they may practice their inventions, or license
others to do so. The grant of a patent permits the inventor to receive a return on the
expenditure of resources leading to the discovery, often by charging a higher price
than would prevail in a competitive market.
The USPTO does not identify or prosecute patent infringers. Instead, each
patentee bears responsibility for monitoring its competitors to determine whether they
are using the patented invention or not. Patent proprietors who wish to compel others
to observe their intellectual property rights must usually commence litigation in the
federal courts.
An accused infringer may contend that the asserted patent is invalid.20 Such an
argument asserts that the USPTO improvidently granted the patent. However, by
virtue of having been approved by the USPTO, each issue patent enjoys a
presumption of validity. Accused infringers bear the burden of proving that a patent
is invalid by clear and convincing evidence.21
Interested parties possess another mechanism for challenging the validity of an
issued patent. They may request that the USPTO commence an administrative
revocation proceeding termed a “reexamination.” In order to provoke a
reexamination, an individual must present the USPTO with one or more pertinent
patents and printed publications. If the USPTO agrees that these references raise a
substantial new question of patentability,22 the agency will subject the patent to a
renewed prosecution in light of this additional information.
The maximum term of patent protection is ordinarily set at 20 years from the
date the application is filed.23 The patent applicant gains no enforceable rights until
such time as the application is approved for issuance as a granted patent, however.

gains no enforceable legal rights until the USPTO allows the application to issue as a
granted patent. A number of Patent Act provisions may modify the basic 20-year term,
including examination delays at the USPTO and delays in obtaining marketing approval for
the patented invention from other federal agencies.

Once the patent expires, others may employ the patented invention without
compensation to the patentee.
Contemporary Patent Administration Challenges
The USPTO currently faces many challenges. Notably, the number of filed
patent applications has increased significantly in recent years. In 1991, the USPTO
received 178,000 applications. By 2000, this number had increased by 75% to nearly24
315,000 applications. One USPTO study estimates that over 500,000 patent
applications could be filed during the 2006 calendar year.25
The increase in patent filings may be due in part to the growth in the range of
subject matter eligible for patenting. Until recently, the patent system was generally
regarded as concerning the technological inventions of traditional industry.26 Modern27
developments have expanded the range of innovations eligible to be patented. In
particular, computer software and business methods may now be subjected to patent28
protection. Some commentators believe that the USPTO may face more difficulties
while examining applications covering inventions from disciplines with which it was29
historically unfamiliar.
As technology grows more sophisticated, patent examination tasks may also
become more difficult. Recent growth in filing rates has been more pronounced in
complex, high-technology fields such as biotechnology, computers and
telecommunications.30 Such inventions may require more time and more technically
sophisticated personnel than was required with predecessor technologies. For
example, one biotechnology application alone arrived at the USPTO with 12 CD’s31
of accompanying data, the equivalent of six million pages of information.
The USPTO has also faced staffing issues. The task of patent examination
sometimes involves subtle legal and technical issues. Hiring and training individuals
to perform these tasks has been a recurring issue for the agency. The USPTO
employed 3000 examiners at the close of 2001, but explains that it needs to hire 700

more during 2002.32 In addition, retaining skilled individuals has been difficult given
the availability of lucrative intellectual property jobs in the private sector. As
recently as 2000, the annual examiner attrition rate was 14%.33
Budgetary pressures have also impacted the USPTO. The agency budget is
supplied entirely from filing and issuance fees, with no monies taken from the
general budget.34 In recent years, however, surcharges, fee diversions and other
measures have resulted in the reallocation of a portion of USPTO revenues into the
general budget.35 Such revenue shortfalls may be impacting the capabilities of the
USPTO. In particular, the average time the agency takes to process an application
has increased from approximately 18 months in 1991 to its current level of 26
Judicial precedents may also be placing more burdens upon the USPTO. Recent
decisions from the U.S. Court of Appeals for the Federal Circuit, the USPTO’s
reviewing court, have increased the agency’s obligations when issuing rejections of
patent applications.37 The USPTO must now articulate in a detailed fashion its
specific factual findings in order to reject a patent application.38 The requirement that
the USPTO explain its reasoning in a particularized and thorough manner may
increase the time the USPTO requires to process applications.
The Impact of Patent Quality Upon Innovation
Some commentators believe that perceived deficiencies in patent administration
may negatively impact innovation. Increases in patent pendency periods may amount
to one such deficiency. According to the USPTO, the average U.S. patent issues
about 26 months after an application is filed, compared with 21 months in 1996. The
USPTO reportedly projects that average patent pendency will increase to more than39

38 months by 2006.

Many observers have suggested that delays in processing patent applications can
lead to deleterious consequences.40 Especially in industries where product cycle

times are short, patents that were the subject of lengthy prosecution periods may be
obsolete by the time they issue. Commenting about the software industry, patent
attorney George F. Wheeler said that “by the time we get a patent issued, the
infringers are done; and we are already on the next product."41
As a result, patent acquisition delays may discourage inventors from using the
patent system at all. Inventors might instead prefer to take advantage of the
immediate protections available under the trade secret law. The incidents of trade
secrecy protection – ranging from physical security measures such as safes and fences
to confidentiality agreements that may limit the ability of employees to interact with
one another -- may in turn lead to costs that may not be socially productive.42
Long periods of delay may also create industrial uncertainties. Enterprises may
establish industries based on technologies that are believed to fall within the public
domain. Years later, the USPTO might allow a patent to issue that covers these basic
technologies. Such patents are sometimes termed “submarine” patents, and they
potentially grant their owner a broad proprietary interest affecting established
In addition to delay, trends towards an increasing number of filed applications,
more complex technologies, and less generous budgets may result in less rigorous
patent examination procedures. Faced with an increasingly difficult examination
environment, the USPTO may approve some patent applications that do not meet the
patentability requirements under the Patent Act. Some commentators believe that
this prospect of “low patent quality” may lead to certain socially undesirable results.
Large numbers of inappropriately granted patents may negatively impact
entrepreneurs. For example, innovative firms may be approached by an individual
with a low quality patent that appears to cover the product they are marketing. The
innovative firm may recognize that the cost of challenging a patent even of dubious
validity may be considerable. Therefore, the firm may choose to make payments
under licensing arrangements, or perhaps decide not to market its product at all,
rather than contest the patent proprietor’s claims.
Some enterprises have also been accused of creating “patent thickets,” or
clusters of closely related patents that cover different aspects of a particular
technology.44 For example, a drug company may own a suite of patents covering not
just the pharmaceutical compound, but also various formulations, chemical

intermediates, metabolites, and methods of manufacturing and using the
pharmaceutical. Some enterprises have been said to cause follow-on patents to issue
as earlier patents are set to expire, resulting in an “evergreening” portfolio that
effectively extends patent term beyond the twenty-year statutory period.45
Improvidently granted patents are also believed to create duplicative
transactions costs. For example, if the patent quality is low, private parties must
engage in extensive due diligence efforts in order to assess whether particular issued
patents are enforceable or not. The result may be that the innovative community
must consistently conduct their own private patent examinations, revisiting the work
of the USPTO to see if it was done properly.
Poor patent quality may also encourage activity that is not socially productive.
Perhaps attracted by large damages awards and a potentially porous USPTO, rent-
seeking entrepreneurs may be attracted to form speculative patent acquisition and
enforcement ventures. Industry participants may also be forced to expend
considerable sums on patent acquisition and enforcement.46 The net results would
be reduced rates of innovation, decreased patent-based transactions, and higher prices
for goods and services.
Although low patent quality appears to affect competitors of a patentee, patent
proprietors themselves may also be negatively impacted. Patent owners may make
managerial decisions, such as whether to build production facilities or sell a product,
based upon their expectation of exclusive rights in a particular invention. If their
patent is declared invalid by the USPTO or a court, the patentee will be stripped of
exclusive rights without compensation. The issuance of large numbers of invalid
patents would increase the possibility that the investment-backed expectations of
patentees become unsettled.47
The Appropriateness of Patent Administration
To the extent there are perceived problems of patent quality, potential fiscal,
technological and staffing challenges to the U.S. patent administration regime may
prompt consideration of legal reform. Before considering possible legal reforms
further, however, it should be noted that at least two factors suggest that current
patent administration practices should be retained. First, not everyone agrees that
additional resources should be devoted towards augmenting the rigor of patent
examination. Second, the USPTO may already be engaged in the best practices
available to a patent-granting agency.

45See Alfred B. Engelberg, “Special Patent Provisions for Pharmaceuticals: Have They
Outlived Their Usefulness?”, 39 IDEA: Journal of Law and Technology (1999), 389.
46Merges, supra note 2.
47See Craig Allen Nard, “Certainty, Fence Building and the Useful Arts,” 74 Indiana Law
Journal (1999), 759.

As to the first of these factors, the notion that USPTO should perform an
extremely rigorous examination has been challenged.48 Some commentators believe
that interested private parties are often able to assess the robustness and value of
individual patents more easily than the USPTO. As a result, a USPTO “hard look”
during its examination procedures may be economically inefficient. Others observe
that relatively few patents are believed to be licensed or the subject of litigation.49
Under this view, society is better served if that select number of valuable patents is
subject to a rigorous review by private parties after their issuance.
As well, the USPTO may already employ the best available practices during
patent examination. Surveys of patent applicants indicate that their overall
satisfaction rate increased from 52% in 1998 to 64% in 2000.50 Although this largely
favorable response suggests some room for improvement, it may not motivate
significant patent administration reforms. On the other hand, given that applicants
are presumably motivated to obtain issued patents, one might question the
appropriateness of surveying applicants to determine whether the USPTO is
performing its functions at a suitable level.
Acceptance of either of these views leads to the conclusion that patent
administration reform efforts would be inappropriate. Unfortunately, no rigorous
analytical methods are available to weigh the propriety of these positions. The
relationship between innovation and patent rights remains poorly understood.
Current economic and policy tools simply do not allow us to set the appropriate level
of patent quality precisely in order to produce an optimal level of investment in
Nonetheless, uncertainties inherent in the patent law reform process should be
weighed carefully when considering modifications to the current patent
administration regime. This report will review several different avenues for patent
administration reform, in the event that legal reforms are deemed appropriate.
Possibilities for Patent Administration Reform
Patent administration reform proposals may be divided into three groups. Some
of these proposals have attempted to increase the responsibilities of patent applicants.
A second set have encouraged third parties to assist the patent office during the
examination process. A third group of proposals have offered more general
mechanisms for reducing patent office workload. Each category potentially provides

practical policy tools for assessing and potentially reforming contemporary patent
Increased Applicant Responsibilities
Under current U.S. law, the principal obligation of inventors is to prepare
truthfully an application fully describing and distinctly claiming the invention for
which a patent is sought.52 Inventors must also submit an oath stating they believe
themselves to be the original and true inventor.53 Once an inventor submits a patent
application, the responsibility wholly falls to the patent examiner to identify the state
of the art and analyze whether the application claims a sufficiently inventive advance
to merit a patent.54 If the examiner cannot provide sufficient reason to reject the
application, it must be allowed to issue as a granted patent.55
Some commentators have noted the limited role of the applicant during patent
examination. They have offered reform proposals that have discussed augmenting
the responsibilities of patent applicants. The following proposals, some of which
have been implemented in terms of patent office programs, provide different ways
of increasing applicant obligations.
Compelled Prior Art Searches. Some commentators have suggested that
patent applicants be required to conduct their own searches of the earlier scientific
and patent literature.56 Such documentation of the state of the art is termed the “prior57
art” in the patent law. Currently, inventors need not conduct a prior art search
before filing a patent application. Although some inventors probably do conduct
such a search, in order to see whether their invention would be considered
patentable,58 the Patent Act currently does not compel such a search.
A mandatory prior art search could potentially provide certain benefits to the
patent examination procedures. A compelled search could cause some applications
not to be filed at all, as inventors realized that their inventions were already within
the state of the art. Those applications that were filed would presumably be more
carefully tailored in light of the existing prior art.
Some commentators are less sanguine that a compelled prior art search would
yield practical benefits. Skeptics believe that a mandatory prior art search would lead
to the disclosure of many prior art documents, but not necessarily the most pertinent

ones.59 Also, although searches could be readily compelled, it seems more difficult
to mandate the quality of the searches.60
A related approach proposal calls upon an applicant to reveal whether he has
completed a prior art search or not and, if so, where the applicant has searched.61
Although this proposal does not compel a search, it could nonetheless save examiners
from redundant efforts when a search has already been completed. Examiners would
be able to move immediately to prior art libraries that were not previously considered
by the applicant. This proposal seemingly suffers from the same drawback as a
compelled prior art search, however, in that monitoring the quality of a disclosed
search may be difficult.
The effectiveness of either of these proposals might be improved if the entire
USPTO prior art library were readily available to the public. The USPTO prior art
database could, for example, be made available on the Internet. In such a case, an
applicant could tell the examiner exactly which databases had been searched. As
computerized search tools become increasingly prevalent, applicants might also
disclose search terms and other searching methodologies. This technique might
allow the USPTO to avoid redundant efforts, yet stand in a position to assess the
quality of applicant searches.
Use of Jepson Claims.Inventors are required to claim distinctly the62
invention they regard as proprietary. As a result, patent instruments include one or
more “claims” that define the patented invention. The U.S. patent statute does not
require that claims be written in any particular fashion. However, USPTO practice
mandates that each claim consist of a single sentence.63 In somewhat simplified
form, the following patent claim is drafted in a manner commonly found in U.S.
patent instruments:
A bicycle, comprising:
a frame;
one or more wheels;
a means for propelling said bicycle; and
a fender over the frontmost wheel.
Many such patent claims can be drafted in the fashion of a “Jepson claim.” This
claim’s name is based on a case, Ex parte Jepson, which was ruled on in 1917. A
Jepson claim defines an invention in two parts. First, a preamble recites the features
of the invention that were known to the public domain. The second, or characterizing

portion of the claim states the technical features that the invention adds to the public
domain.64 Rewritten in Jepson style, the above claim could be expressed as follows:
A bicycle having a frame, one or more wheels, and a means for propelling
said bicycle, wherein the improvement comprises:
a fender over the frontmost wheel.
Under the Jepson claim format, the applicant admits that the subject matter within
the preamble of the claim constitutes prior art. Only the subject matter within the
body of the claim is asserted to be inventive.65
Many U.S. patent attorneys prefer not to use Jepson claims. Some patent
attorneys believe Jepson claims tend to portray the invention as a limited
improvement, rather than an elegant combination of diverse elements that together
produce an inventive advance.66 Conversely, USPTO examiners generally prefer to
receive such claims.67 Jepson claim format is said to make prosecution more
compact, for the claim itself identifies the state of the art and the inventor’s asserted
technical contribution.
The present policy of the EPO is to encourage applicants to use Jepson claim
format.68 One possibility is that the USPTO do the same. Drafting claims in the
Jepson format appears to raise few additional costs or inconveniences on behalf of
patent applicants. On the other hand, the benefits of obligatory Jepson claims may
be modest. Jepson claims are likely most effective when the applicant has completed
a prior art search, and therefore is better able to identify technical features that fall
within the state of the art. If such a search has not been done fully, or at all, then
Jepson claims may not be of significant assistance to examiners.
USPTO Rule 105. The USPTO has recently promulgated Rule 105, titled
“Requirements for information.”69 Rule 105 allows examiners to require applicants
to submit a broad range of information, including any materials referenced during the
drafting of the application, literature consulted during the invention process and70
identification of any predecessor technology that the invention improves. If a
complete reply is not forthcoming, the application may be considered abandoned.71

7037 C.F.R.. § 1.105(a)(1).
7137 C.F.R. § 1.105(c).

Rule 105's significance is that it provides examiners with explicit authority to
ask for information that may be reasonably necessary to examine an application
properly. Examiners have traditionally lacked inquisitorial powers and, absent
unusual circumstances, are resigned to accept sworn applicant submissions as truth.72
Rule 105 alters this passive stance by providing examiners with the ability to query
applicants more actively. As explained by Nicholas P. Godici, former Acting Under
Secretary of Commerce for Intellectual Property and Acting Director of the USPTO,
USPTO management is “hopeful that Rule 105 will further enable our examiners to
perform the best examination possible, with applicants' assistance.”73
It is difficult to assess whether USPTO examiners have actually made much use
of Rule 105. Because patent applications have traditionally been maintained in
secrecy,74 observers are often unable to track the process of individual applications
until the date a patent issues. From the perspective of examiners, however, Rule 105
involves a potentially time-consuming process of drafting a statement and parsing the
applicant’s response. Use of Rule 105 may also not necessarily supply an examiner
with additional information. The rule provides that if an applicant states that the
requested information is unknown or not readily available, then examiners must treat
that answer as a complete reply.75
Focus on the Patent System’s Heaviest Users. Some entities employ
the patent system more frequently than others. For example, fourteen enterprises
were awarded 1000 or more U.S. patents in 2000; an additional 151 obtained at least

100 patents. These 165 enterprises received in total 56,105 patents – about 35.6%76

of the 157,497 utility patents granted that year. These statistics reveal that over
one-third of the USPTO’s efforts are devoted to 165 large customers.
The JPO has relied upon frequent filers before. Through the so-called “Action
Program for 80%,” the JPO caused its best customers to devote more resources to the
preparation of patent applications.77 The thinking behind “AP 80%” was apparently
to ease the task of examiners by presenting them with more applications that were
amenable to quick review and allowance. Through AP 80% the JPO requested that
large applicants endeavor to increase their individual allowance rate to 80%. Among
the steps applicants could take to reach the 80% allowance plateau were conducting

augmented prior art searches, requesting that fewer filed applications be examined,
and, of course, making more selective filing decisions in the first place.
Other patent offices might also call upon their largest users to assist in the patent
examination process. The USPTO could mimic the JPO Action Plan for 80%, for
example, asking “Century Club" members to place their applications in a better
position for timely examiner review. Larger users might perform initial
classifications and prior art searches with respect to their own applications, on behalf
of the USPTO and under its supervision.
Other arguments suggest that all applicants should be treated equally, however.
Applicants pay the same fees no matter how many applications they file.78 The
number of patents a particular enterprise obtains varies from year to year, suggesting
instability among the individual participants in this proposed program. Larger
applicants might also appear to be the preferred customers of the USPTO under such
a regime.
Encourage Third Party Involvement
Commentators have proposed that the USPTO make more effective use of
interested parties to assist in the task of patent examination.79 Entities outside the
USPTO may possess certain informational advantages over the corps of examiners.
Current participants in the marketplace may possess a better sense of the state of the
art, for example, than the USPTO.80 By allowing these third parties to play a role as
“private patent examiners,” the USPTO may be able to make better patentability
decisions than it could through its own resources. Two principal mechanisms for
encouraging third party involvement, opposition proceedings and pre-grant
publication of pending applications, are considered here.
Opposition Proceedings. Many foreign patent regimes allow for so-called
opposition proceedings. An opposition is a patent revocation proceeding that is
usually administered by authorities from the national patent office. Oppositions often
involve a wide range of potential invalidity arguments and are conducted through
adversarial hearings that resemble courtroom litigation.
Although the U.S. patent system does not include oppositions, the U.S. patent
system has incorporated a so-called “reexamination” proceeding since 1981. Some
commentators have viewed the reexamination as a more limited form of an
opposition.81 Under the reexamination statute, any individual, including the patentee,
a competitor, and even the USPTO Director, may cite a prior art patent or printed
publication to the USPTO. If the USPTO determines that this reference raises a

“substantial new question of patentability” with respect to an issued patent, then it
will essentially reopen prosecution of the issued patent.
Traditional reexamination proceedings are conducted in an accelerated fashion
on an ex parte basis. Following the American Inventors Protection Act of 1999, an
inter partes reexamination allows the requestor to participate more fully in the
proceedings through the submission of argument and the filing of appeals.82 Either
sort of reexamination may result in a certificate confirming the patentability of the
original claims, an amended patent with narrower claims or a declaration of patent
Congress intended reexamination proceedings to serve as an inexpensive
alternative to judicial determinations of patent validity.84 Reexamination also allows
further access to the legal and technical expertise of the USPTO after a patent has
issued.85 However, some commentators argue that reexamination proceedings have
been employed only sparingly and question their effectiveness.86
Legislation introduced in the 107th Congress would introduce opposition
proceedings into U.S. patent law.87 Supporters of full-featured oppositions believe
that opposition proceedings will succeed where reexamination has arguably failed.88
Some detractors believe that oppositions can be used to harass a patentee, however.89
Other detractors question the capacity of the USPTO to administer oppositions,90
while still others question whether oppositions can ever fully substitute for
proceedings in federal court.91
Publication of Pending Applications. Most foreign patent regimes92
publish all pending patent applications 18 months after they have been filed. A
perceived advantage of pre-grant publication is that interested parties may inspect the
pending application. Many foreign patent systems allow competitors to submit prior
art documents and commentary upon the pending application. Such submissions may

assist a patent examiner in reaching an appropriate decision about the patentability
of the invention.
Until recent years, the U.S. patent system acted differently from its counterparts
overseas. The USPTO traditionally did not publicly disclose patent applications at
all. Only granted patents were disclosed to the public, upon the day of their issuance.
This regime was said to advantage patent applicants because it allowed them to
understand exactly what the scope of any allowed claims might be prior to disclosing
an invention. Thus, if the applicant was wise enough to maintain the invention that
was subject to a patent application as a trade secret, then he could choose between
obtaining the allowed patent claims and trade secret status.93
However, this secrecy regime has been perceived as imposing costs as well.
Others might well engage in repetitive research efforts during the pendency of patent
applications, unaware that an earlier inventor had already staked a claim to that
technology. This arrangement also allows inventors to commence infringement
litigation on the very day a patent issues, without any degree of notice to other
members of the technological community.94
The Domestic Publication of Foreign Filed Patent Applications Act of 1999,
which was one component of the American Inventors Protection Act of 1999, P.L.
106-113, altered the U.S. regime. The Domestic Publication of Foreign Filed Patent
Applications Act allowed inventors to take advantage of a secrecy regime where
patent filings concerned only the United States, but acknowledged that inventors who
sought patent protection abroad were already subject to pre-grant publication
overseas. Under this statute, U.S. patent applications are published after the
expiration of18 months from the date of filing. There is an exception, however, if
the inventor represents that he will not seek patent protection abroad. If an applicant
certifies that the invention disclosed in the U.S. application will not be the subject of
a patent application in another country that requires publication of applications 18
months after filing, then the PTO will not publish the application.95
The Domestic Publication of Foreign Filed Patent Applications Act of 1999
includes a significant qualification:
Protest and pre-issuance opposition.--The Director shall establish appropriate
procedures to ensure that no protest or other form of pre-issuance opposition to
the grant of a patent on an application may be initiated after publication of the96

application without the express written consent of the applicant.

is charged with notifying the USPTO so that its U.S. application may be published.
9635 U.S.C. § 122(c).

Commentators have identified this provision as prophylactic in nature.97 It was
reportedly designed to prevent post-publication harassment by third parties, who
might be motivated to flood the USPTO with protests against pending applications.98
In accordance with this statute, the USPTO established Rule 99, a new
regulation addressing third party submissions that pertain to published patent
applications. The USPTO allows interested members of the public to submit prior
art patents and publications that pertain to a published application. However, the
USPTO will not accept argumentation or explanation of those references. As stated
in Rule 99:
A submission under this section shall not include any explanation of the patents
or publications, or any other information. The Office will dispose of such99
explanation or information if included in a submission under this section.
In other words, the USPTO will accept any prior art references submitted by
interested members of the public in response to the pre-grant publication of a pending
patent application. The USPTO will not consider any argument or explanation
accompanying those references.
This compromise seemingly allows the USPTO to avoid potentially entangling
advocacy by third parties during prosecution. But it may diminish the effectiveness
of public input into patent examination. Interested members of the public may also
be less inclined to forward pertinent references to the USPTO if they cannot submit
accompanying commentary. They may reason that the better course is to allow the
reference to be considered for the first time during litigation, where they may offer
a full argument, possibly in front of a jury.100
Workload Reduction
A number of legal reform proposals and existing patent office programs
generally relate to workload reduction. This report identifies three of these
proposals: deferring examination, limiting examination tasks and promoting
international worksharing.
Deferred Examination. Every application filed at the USPTO is
automatically placed into a queue for substantive examination. One distinct aspect
of patent practice in some other nations is that examination is deferred following

Disclosure Procedure for Published Pre-grant Applications,” 83 Journal of the Patent and

Perspective,” American Law Institute - American Bar Association Continuing Legal

submission of an application. Stated differently, in many other patent-issuing states
the mere filing of an application does not mean that the patent office will further
consider the application. Inventors who wish their applications to mature into an
issued patent must submit additional requests in order for the patent office to
consider the application. Such requests must occur within a specified time and be
accompanied by the appropriate fee. In Germany, an inventor may defer examination
for up to seven years;101 in Japan, the maximum deferral period was recently reduced
from seven to three years.102 If no request for examination is made in a timely
fashion, the application is deemed abandoned. If a request for examination is
seasonably made, the novelty and nonobviousness of the application are judged as
of the application’s filing date.
Supporters of deferred examination regimes observe that they allow applicants
the option of deciding to postpone the decision as to whether to obtain patent
protection. Deferred examination regimes may also reduce patent office workloads.
Further, since all pending applications are published approximately 18 months
following their filing dates, the public has notice of the prospect of a granted patent
whether examination is deferred or not.103 Detractors note that a deferred
examination system may delay the issuance of a fully considered patent instrument
and, as a result, substantially increase marketplace uncertainties.
Limited Examination Tasks. The USPTO currently operates under an
“examination” regime. Each patent application presented to the USPTO is reviewed
to determine whether the invention described therein meets the requirements of the104
patent laws. An alternative to examination is a so-called “registration” system.
Under a registration regime, patent applications are simply recorded and issued. No
formal review of the application occurs. If a patent is asserted, determination of its
validity is wholly left to the courts.105
Early in its history, the United States operated under a registration system. From106
1793 through 1839, patents were registered without formal review. Various
foreign patent systems have also employed registration schemes during their history.
For example, since 1995 the Dutch patent system has largely acted as a registration

Marshall Law Review (1995), 269.

Registration systems may be less expensive to operate than examination
systems, at least initially. They would appear capable of acting more quickly than
examination systems.108 However, registration regimes provide less certain rights
than an examination system and may encourage frivolous filings. As a result, more
burdens may be placed upon the courts and private enterprise to determine which
registered patents are valid and enforceable.109
International Worksharing. No global patent system exists. There is no
mechanism for an inventor to obtain an “international patent.” Individuals who wish
to obtain patent protection in several countries must instead file applications on an110
individual, nation-by-nation basis. In turn, the patent offices of the world will
examine these applications in parallel, each providing an independent decision on
whether the application should be approved or not. For example, if an inventor
wishes to obtain patent protection in the United States, Japan and Germany,
essentially the same examination tasks will be performed by three different
ex am i n ers. 111
Observers have suggested that it is inefficient for multiple patent offices to112
examine parallel applications. Even absent a global patent system, the world’s
patent offices could respect the examination results of their peer agencies. Once an
application was approved by one patent office, the other patent offices could provide
some level of deference to that result. The deference could range from a “soft look”
by the USPTO at an application that was approved elsewhere, to a very lenient
review that would effectively amount to a registration of that application.113
Some practical difficulties may attend this worksharing proposal. The U.S.
patent laws differ from those of many foreign states. For example, only the U.S.
employs a first-to-invent priority principle, where a patent is awarded to the first114
actual inventor rather than the first individual to file a patent application. Unlike
many of its trading partners, the U.S. also imposes a “best mode” requirement, where
inventors must disclose the preferred way of which they are aware to practice the

invention.115 U.S. law also allows patents to issue on business methods, while many
foreign patent systems do not.116
Another potential problem with worksharing proposals is that the United States
may lack the ability to monitor the rigor of foreign examination procedures. If
foreign patent offices lack stringent examination protocols, the USPTO may have to
allow invalid patents to issue. To the extent that the USPTO would actually monitor
issued patents from foreign offices under these proposals, the benefits of a
worksharing arrangement may be reduced.
Experience with the Patent Cooperation Treaty, or PCT suggests this possibility.
The PCT provides for the filing of one patent application that can lead to issued
patents in many countries.117 An inventor may use the PCT if he is a national or
domicile of a PCT contracting state. Most often, an inventor commences the PCT
process by filing a so-called “international application” at his local patent office. The
international application designates all PCT member states in which the inventor
wishes to obtain patent protection. An international application has the effect of a
national application in all of the countries that the applicant designates.
This application will then be sent to one of the individual national patent offices,
including the USPTO, EPO and JPO, that are designated as an International
Searching Authority. These patent offices research existing patent documents and
other technical literature in order to determine public domain knowledge pertinent
to the invention claimed in the patent application. The applicant then receives an
international search report, which lists citations of prior art relevant to the claims of
the international patent application and gives an indication of the possible relevance
of the citations to the questions of novelty and nonobviousness.
If the international search report does not reveal any public domain knowledge
that would defeat the patentability of the claimed invention, the applicant may wish
to enter the second part of the PCT process, the so-called “national stage.” Here the
applicant submits the PCT application to various national offices. At this time,
patent examiners in each country examine the application based upon their own
national laws, either allowing or rejecting the patent application.
The PCT framework appears to provide opportunities for the world’s patent
offices to rely upon the efforts of their colleagues. The USPTO could simply accept
the international search report and commence with substantive examination.
Experience suggests, however, that this benefit may not have been fully achieved.
A perceived difficulty with the PCT is that many patent offices do not appear to
respect fully the work product of the International Searching Authority. In fact, most
patent offices normally repeat the search and examination at the national phase in the
same manner as for an ordinary national application. A possible reason for this

Thomas, CRS Report RL30572, 1 June 2000.

posture is that many PCT signatories do not fully respect the rigor of the examination
proceedings elsewhere. Under the view of some observers, these redundant efforts
appear to undermine much of the logic behind PCT.118
Concluding Observations
The technical, fiscal and industrial environment in which the patent examination
system exists presents a number of challenges for the USPTO. In turn, patent
administration potentially holds implications for innovative U.S. industry. Given
their lack of market power, small businesses and independent inventors have been119
perceived to rely more heavily upon the patent system than larger firms.
Entrepreneurs and small, entrepreneurial firms may therefore possess a substantial
stake in the rigor of patent examination proceedings.
To the extent that patent administration is believed deserving of further
attention, a number of existing programs and proposals suggest possibilities for
improvement. Each of these avenues for reform promises benefits but may also lead
to costs and complexities. Selection from this range of possibilities will require a
careful balancing of the potential advantages and possible drawbacks of patent
administration reform.
