    President Bush signed on November 2, 2002, omnibus legislation passed by the U.S. Congress that includes significant changes in U.S. patent laws. Notably, the new law lifts certain restrictions on patent reexamination, and clarifies the "prior art" status of U.S. patents and published U.S. patent applications. See first two items below.

    Patent reexamination: reference previously considered by PTO

    The new law allows the PTO to consider a new reference cited by a requester in support of the reexamination of a patent, even though the reference has already been cited or considered by the PTO in the examination of the application which issued as the patent in question. The reference may be considered again by the PTO to determine whether it raises a "substantial new question of patentability," which would cause the PTO to grant the request for reexamination of the patent. This provision applies to all reexamination proceedings in which the determination of the existence of a substantial new question of patentability is made on or after the date of enactment of the new law, i.e., November 2, 2002. The provision applies to intra partes reexamination (in which the requester is a third party who is not the patent owner and is precluded from participation past the stage of filing a request for reexamination), as well as inter partes reexamination in which the third party is allowed to participate throughout the entire process.

    Inter partes reexamination: third party requester may appeal
    Since the inter partes reexamination procedure was made available by the American Inventors Protection Act of 1999, there have been only five (5) requests filed for inter partes reexamination. The new law removes a distinct disadvantage for third party requesters in inter partes reexaminations, by allowing them to appeal a decision of the PTO's Board of Patent Appeals and Interferences to the U.S. Court of Appeals for the Federal Circuit (CAFC), or to be party to such an appeal. This provision applies to any reexamination begun on or after the date of enactment of the law, i.e., November 2, 2002.

    Correction of Section 102(e)
    The long-awaited "technical corrections" to section 102 (e) of the U.S. patent laws remove ambiguities introduced the last time that section 102(e) was amended by enactment of the American Inventors Protection Act of 1999. Section 102(e) defines a category of "prior art" against which the patentability of the claims of a U.S. patent application is measured. Prior art under 102(e) was previously limited to granted U.S. patents. When the American Inventors Protection Act of 1999 mandated that U.S. patent applications be published within 18 months of their filing dates, section 102(e) was also amended to designate such pre-grant publications to be prior art under section 102(e).

    The prior art defined by section 102(e) is significant in that its effective date is the filing date of the patent application from which the prior art, which is either a granted U.S. patent or a pre-grant publication of a U.S. patent application, originates. For illustration, when U.S. patent application A is published, the publication of A serves as prior art against other U.S. patent applications filed after the filing date of application A. Thus, if application A is published today, for an invention which was kept secret until the publication of the application, the publication of A can be applied as 102(e) prior art against other applications filed after the filing date of application A, even if such other applications are filed before the publication date of A. Because of its effective date, 102(e) prior art is potent in preventing another person from patenting an invention that is identical or obvious from the invention described in publication A.

    The ambiguities in 102(e) as amended by the American Inventors Protection Act of 1999 stemmed from the treatment of patents or published applications originating from an international patent application filed in the Patent Cooperation Treaty (PCT) system. Even though the new law brings much needed clarification, section 102(e) is still rather complicated because it provides for a transition around the date of November 29, 2000, set in the American Inventors Protection Act of 1999.

    (i) For International Application Filed Before November 29, 2000 A U.S. patent issuing from the entry into the U.S. national stage of an international application is 102(e) prior art, for which the effective date is the date on which certain requirements for entry into the U.S. national stage were completed (e.g., filing of a declaration for patent application, submission of any required translation, and payment of the requisite fee.) The cover page of the U.S. patent in such a case indicates clearly the "102(e) date" accorded to that patent, which is never the international filing date.

    (ii) For International Application Filed On or After November 29, 2000 A U.S. patent or an application publication originating from an international patent application filed on or after the November 29, 2000 transition date is 102(e) prior art only if: (1) the international patent application designates the United States, and (2) the international patent application is published in English by the World Intellectual Property Organization (WIPO) in its regular publication program under PCT Article 21(2), as opposed to a special publication initiated by the applicant. The effective date of such a 102(e) reference is the international filing date of the application. To understand the rationale for this provision, it may be helpful to think that an international patent application that designates the United States and is published in English is in effect the same as a published U.S. patent application, and logically should be accorded the same treatment for purposes of section 102(e).

    The new 102(e) provision will be applied across the board to all patent applications undergoing examination, regardless of their filing dates.

    Soon after the new law was signed, the PTO issued new examination guidelines for use by U.S. patent examiners in selecting 102(e) prior art to be applied against the claims of a patent application under examination. The guidelines set forth the PTO's interpretation of the new law, and include useful examples of what is considered 102(e) prior art by the PTO.

    (iii) PCT "Bypass Continuation Application" Confers No 102(e) Advantage Prior to enactment of the American Inventors Protection Act of 1999, applicants who filed international applications in any of the PCT member countries other than the United States, and designated the United States as a country in which patent protection was sought, had resorted to the so- called "bypass continuation application" to secure a beneficial 102(e) date for any U.S. patent granted on the application. In the bypass process, the applicant filed in the U.S. Patent and Trademark Office a regular, domestic U.S. patent application which claimed to be a U.S. domestic "continuation" of the earlier international application. The applicant in effect bypassed the entry into the U.S. national stage of the international application, and by this loophole secured as 102(e) effective date for the granted U.S. patent the international filing date, as opposed to the less favorable and subsequent date of entry into the U.S. national stage of the international application, as discussed in section (i) above.

    The changes made by the Inventors Protection Act of 1999 cast doubt on the utility of the bypass route, although the effect of that law was not clear due to its ambiguous language for section 102(e). The recently signed law now makes it clear that the bypass route confers no 102(e) advantage. In particular, the Joint Explanatory Statement of the Committee of Conference (of the U.S. House and U.S. Senate) for the new law specifies that "for patents and published applications derived indirectly from an international application filed before November 29, 2000 through a bypass continuation application," such patents and published applications are effective as prior art references (under section 102 (e)) "as of the filing date of the bypass continuation application," as opposed to the international filing date.

    Harmonization: formalities; substantive
    The patent system in the United States and in other established patent-granting countries has been a victim of its own success. The number of applications for patents handled by the major patent offices has surged so dramatically in the last few decades that their resources are severely stretched. From the perspective of the users of the patent system, the cost of obtaining, maintaining and enforcing patent protection has been steadily increasing, in part because business strategies require that protection be sought nowadays in more countries. For small business, patent issues may be particularly daunting, not only in terms of costs, but also in complexity. Patent owners, as well as patent granting agencies, are seeking solutions to their respective problems, and legislators are also responding to the needs of their business constituents. As a result, more changes in patenting procedures in the United States and at the international level are expected. Undoubtedly, these changes will come about slowly because of the time needed for consensus building and passage of legislation, in particular in the United States where patent legislation typically moves very slowly through the U.S. Congress.

    Global harmonization of the patent laws is fraught with difficult issues for the United States because it requires considering giving up the first-to-invent system, in which the first inventor to make an invention gets the patent, for the first-to-file system in which the first applicant to file a patent application for an invention gets the patent. The United States is the only country with a first-to-invent system, the first-to-file system being followed by the rest of the world. Attempts to forge a harmonization framework in the last decade failed to produce agreement on substantive points, but resulted in the signing of the Patent Law Treaty (PLT) in 1999 which harmonizes the formalities for filing a patent application. The PLT will enter in force when it is ratified by 10 signatory countries. To date, four countries have ratified the treaty, which has not yet been ratified by the major players in the global patent scene. The United States is a signatory to the treaty, but has not yet ratified it.

    The PLT is expected to enter in force in the next couple of years. The treaty is administered by the World Intellectual Property Organization (WIPO), the United Nations agency which also administers the Patent Cooperation Treaty (PCT). Since the PLT applies to domestic applications as well as international applications, some PCT rules have already been revised to be consistent with the PLT. A notable aspect of the PLT is its forgiveness of unintentionally missed deadlines, such as the one-year Paris Convention period for filing an application in a second country, claiming the priority date of a corresponding application first filed in another country.

    In the opinion of this writer, we are well on the path toward more revamping of the global patent system, inching toward substantive harmonization of patent laws. Who would have believed 10 years ago that U.S. patent applications would be published prior to grant, as in most other patent-granting countries, and that the term of a U.S. patent would be calculated from the application filing date, as opposed to the date of grant, as is also the case in most other countries? Those changes were enacted with the American Inventors Protection Act of 1999. In the same vein, who would have believed 10 years ago that the idea of a first-to- file patent system could be endorsed, albeit with some qualification, by an organization representing U.S. patent owners, as was done recently by the Intellectual Property Owners, Inc.?

    PCT new procedures and e-filing
    In September 2002 the Assembly of the PCT Union adopted in Geneva a number of changes in procedures for international patent applications. For the most part, the changes were proposed by the United States. They will be phased in over the next few years according to the following schedule.

  • October 17, 2002: Reduction by 200 Swiss francs in filing fee for applications filed in electronic form.


  • January 1, 2003: Forgiveness of deadlines missed unintentionally or in spite of due care. This change was adopted to align the PCT procedures with the Patent Law Treaty (PLT) mentioned in the preceding section of this newsletter.


  • January 1, 2004: Implementation of a new EISPE (Enhanced International Search and Preliminary Examination) system in which every application will receive an International Search Opinion (ISO) and an International Preliminary Report on Patentability (IPRP), regardless of whether the applicant proceeds under Chapter I or Chapter II of the PCT. To proceed under Chapter II, the applicant must file a Demand by the deadline that is the later of: (a) three months after the issuance of the ISO, or (b) 22 months from the priority date. The main difference between Chapter II and Chapter I is that the applicant has an opportunity for dialogue with the PCT examiner under Chapter II, but not under Chapter I.


  • January 1, 2004: All countries and regional patent systems will be automatically designated in the PCT Request (i.e., application form), so that the international filing fee will be a flat fee, instead of depending on the number of designations.
  • A PCT pilot program for electronic application filing was initiated in November 2002 at the PCT International Bureau in Geneva, using PCT-EASY extended software for e-filing, and customized COREL software for authoring/editing the application in XML format. The U.S. Patent and Trademark Office is also using the XML format for patent application e-filing, but the authoring/editing tool currently provided by the PTO is customized MS WORD software, which was ruled out for PCT e-filing because of the differences that exist in the versions of MS WORD used around the world.

    Strategic plan: drastic changes for PTO
    In response to a congressional mandate, the PTO has prepared a five-year strategic plan that is causing great stir in the patent communities because it proposes extensive changes in examination procedure and large fee increases. All these changes require passage of legislation, which is not expected to happen any time soon. However, one element of the strategic plan already has been incorporated into the bill signed into law by President Bush in November: the goal of complete conversion to e-filing of patent applications by October 1, 2004.

    Carlyle campus construction on schedule
    Construction of the PTO's Carlyle campus in Alexandria, Virginia, is proceeding on schedule according to PTO officials. Technology Center 1600 (Biotechnology, Organic Chemistry, and Designs) and other patent examining groups are scheduled to move into two new buildings by November 2003. Full occupancy of the five interconnected buildings planned for the new campus is expected by mid-2005.
