7. Patent Office-SSO Information Sharing1

7.1 Origins and Scope of Information Sharing

Until recently the standard-setting process has operated largely independently from patent examination and grants. However, as the interplay between standards and patents has increased, along with the number of patents in the technologies comprising ICT, so has recognition that the two systems’ functioning and integrity are interdependent. Particular technologies are often both vital to the standards in which they are incorporated and protected by patents. At the same time, implementers who are obliged to license standard-essential patents and often pay royalties for their use have a considerable stake in the quality of issued patents.

In determining whether the subject matter of a patent application is novel, patent office examiners rely on databases of previous patents, publications, and other documents, referred to as prior art.2 The submissions by participants to standards bodies represent a potentially valuable collection of prior art, consisting of patents, patent applications, and technical specifications. These include finalized standards documents, preliminary and temporary drafts, and other disclosures of technical information to working groups.

These standards-related materials are thought to affect 30 to 40 percent of patent applications in certain ICT fields.3 Patent offices and standards bodies are considering ways of cooperating to increase the availability to examiners of standards documentation that will improve the examination process. One institu-

tion in particular, the European Patent Office (EPO), has concluded groundbreaking agreements with three SSOs to share such information.

The EPO is the regional patent office established by the 1973 European Patent Convention among 38 member states. It examines patent applications submitted by inventors worldwide. Applications approved by the EPO may be granted EPO patents and also granted by the patent offices of individual member states.4 The EPO processes the third largest volume of patent applications in the world after the Chinese State Intellectual Property Office (SIPO) and the USPTO.

In recent years the EPO concluded memoranda of understanding with three standards organizations. The first agreement was the Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA), which develops global standards for a wide range of IT products and services. The second memorandum was with the European Telecommunications Standards Institute (ETSI), which also produces globally-applicable ICT standards. Finally, the third agreement was with the International Telecommunications Union (ITU), the United Nations specialized agency for creating global standards in information technology and communications.

The three agreements have several common elements: 1) exchange of information and documentation of mutual interest in the field of standards for the benefit of prior art search; 2) collaboration on documentation format definition and dissemination policies to align them with the EPO prior art search needs; 3) contributions to education activities in the field of standards; and 4) self-funding of expenses associated with the agreements.

Of the three arrangements, the 2009 ETSI-EPO memorandum of understanding has created the most robust relationship although the two institutions had previously developed a mutual understanding since EPO became a member of ETSI in 2003.5 ETSI is a leading body for globally applicable standards for telecommunications and home of world-class standards such as GSM, TETRA, and DVB. Its membership consists of 766 companies and organizations from 63 countries. Its IPR database contains information on those patents and applications notified to ETSI as being essential or potentially essential to ETSI standards. The value of this database arises from both its comprehensiveness and the structure of relationships in its information architecture, in particular its integration of patent documentation, bibliographic information, patent families, and patent number normalization. Under the agreement with ETSI the EPO has acquired documentation on standard-essential patents from ETSI along with necessary bibliographic data, incorporated the data into its internal databases, and

5EPO has joined other SSOs also to access prior art, often under the same conditions and costs as industry members who profit from their membership, but membership is not a sine qua non of EPO information sharing with SSOs. See discussion below.

educated its examiner corps on how to use data in assessing prior art (Goudelis, 2012).

The EPO is seeking similar working relationships with other standards organizations. In 2012, the Office extended invitations to enter into similar memoranda of understanding (MOUs) to ISO and IEC. The EPO has also shared what it considers its positive experiences with other patent offices (Goudelis, 2012).

7.2 Benefits and Costs of Information Sharing

One measure of the utility of these standards-related information sharing arrangements is the number of times ETSI standards documents have been cited in EPO patent examinations. These citations show a marked decline over the period of cooperation, from 2000 in 2004 to 884 in 2008. No analysis is available of the number of patent applications rejected on the grounds of prior art from these sources, but one can conclude that the data represent a significant addition to the knowledge base available to examiners in the fields covered and have been used to limit the scope of approved patent claims.

The costs of participating in the information sharing arrangements are non-trivial. For the EPO, the costs include membership fees and for the EPO and SSOs, acquisition and conversion costs. Nevertheless, for the EPO, the arrangements contribute to a reputation for relatively efficient search and high quality examination and the benefits are seen to extend beyond generating patents of higher quality. Improved transparency in the linkages between IPR and standards is seen as a benefit by both SSO members and EPO examiners. Disclosure of SEPs, together with a commitment of FRAND licensing, is a requirement of many SSOs. Nevertheless, the amount and quality of information about declared patents may be less than desired by some users of their databases. Generally speaking, SSOs do not perform checks on the essentiality, validity, and completeness of the disclosures. Where disclosure is not compulsory, SSOs are not in a position to provide assurances about the completeness and timeliness of submissions to their databases.

The interlinking of EPO and SSO databases benefits SSO members by providing updated information on patent applications and claims and generating automatic identification of classifications and types of patent families, all subject to the agency’s quality controls. ETSI independently modified its IPR policy to extend disclosure and FRAND licensing commitments from a specified member of a patent family to all existing and future essential patents of that family unless there is an explicit exclusion of specified patents at the time of the undertaking.6

ETSI also took advantage of its cooperation with EPO to launch a new information architecture in 2011, increasing transparency, functionality, and user-

friendliness by such improvements as reliable reporting of query results, information on ownership and essentiality status, and links to information on licensing conditions. The estimated cost of these upgrades was 1 million Euros, or approximately U.S. $1.3 million.

A possible future benefit of EPO-SSO cooperation is in tracking changes in patent ownership. Both participants in standardization development and standards implementers have a strong interest in the availability of accurate, updated information about who owns which SEPs, in which patent jurisdictions, and for how long. Also important is information about whether titles have been reassigned and to whom. The EPO’s ability to track ownership and assignments extends only through the time at which the patent is granted and the nine-month period following, during which an opposition may be filed. Beyond those times information on transfers resides, if at all, in national patent offices. One suggestion to address this challenge of tracking patent transfers is the creation of Internet-based patent registers maintained by standardization bodies in cooperation with patent offices. This idea continues to be discussed in various forums.

Establishing mechanisms to record patent transfers, preferably in the patent office where the national patent was granted, would help in achieving the goal of identifying the ownership of SEP patents.7 Despite practical concerns, such measures would enable an implementer or standards developer to search official records to determine who owns a SEP, whether it is declared or not, and whether it has been assigned.

7.3 Legal Status of Standards Information

Final standards are part of the available prior art, except in the case of private standard consortia that do not publish them but make them available only to specific parties under non-disclosure agreements. Further, preparatory documents are treated like other written or oral disclosures, meaning that to qualify as prior art they must have been made available to the public prior to the patent filing or priority date without the disclosure being subject to a requirement of confidentiality. Thus, the prior art standing of a standards draft may be subject to the rules or norms of the SSO concerned and is not always clear, nor is the date of a document always verifiable.

The incentives for members of SSOs to make early specifications available as prior art are often mixed. In some SSOs, circulation of early drafts of specifications is limited to those working on it, perhaps due to a concern that allowing other parties to comment adversely on preliminary drafts could chill

An article by Nahoko Ono, Avoiding Japanization: Lessons from Japanese Gridlock on the Patent Recordation System (2012) discusses problems with the Japanese system of recording patent documents. The focus of that article is on licensor and licensee concerns with disclosing confidential terms (such as exclusive license scope) and on limiting information to specific information such as grantor, grantee, addresses, and patent numbers.

innovative proposals. There may also be a concern that competing nonmembers, able to read the new specification before it is formally published as a standard, could somehow undermine it. Such considerations are balanced, however, against an interest in early publication in order to foreclose others from patenting technology created during the standards development process.

Under the three MOUs with SSOs, documents provided to the EPO, whether preliminary or final, are considered not to be confidential unless otherwise specified. To date there have been no cases where the participating SSO has excluded use of shared information as prior art. If a patent applicant were to contest use of such documents as prior art, the circumstances would be assessed case-by-case in the course of patent examination.

7.4 Relevance of the European Experience to the USPTO

The committee considered the implications of the EPO-SSO agreements for the U.S. Patent and Trademark Office, which does not participate in them. In this regard, the Scientific and Technical Information Center (STIC), a central library facility operated by the USPTO, frequently receives requests from examiners to provide the text of standards thought relevant to the patentability of inventions under consideration. The application may reference a particular standard or include part of a standard. Further, the examiner may find mention of a standard in the course of the examination.

The STIC provides access to standards documents through a variety of channels, including most frequently its non-patent literature (NPL) website and its subscriptions to the publicly available standards of some SSOs, such as IEEE-SA. In general, these sources are limited to final standards, and obtaining additional documents relating to them may entail a significant cost to the patent office.

For their part, SSOs have access through public search facilities to the same databases of granted patents and pre-grant applications that are available to examiners. However, like other members of the public, they do not have access to the STIC NPL Website. As for patent transfers, assignments, and re-assignments, the USPTO maintains an assignments database. Submissions of information to it are voluntary, although registration does convey some legal protection that would not otherwise exist.

The committee finds that arrangements along the lines of the EPO-SO memoranda could significantly benefit both the USPTO examination process and SSO functioning at relatively modest cost to both parties. We note, however, two issues that would need to be addressed.

First, as does Europe, the United States has its own jurisprudence on when documentation is “publicly available” and therefore eligible as prior art, and cooperative arrangements must take those laws into account. In a recent pertinent case, for example, SRI International v. Internet Security Systems Inc., a

Suggested Citation:"7 Patent Office-SSO Information Sharing." National Research Council. 2013. Patent Challenges for Standard-Setting in the Global Economy: Lessons from Information and Communications Technology. Washington, DC: The National Academies Press. doi: 10.17226/18510.
×

number of patents related to the Internet were alleged to be invalid in view of a prior technical paper. However, the Federal Circuit Court of Appeals ruled that there was “insufficient evidence to show that the paper was publicly accessible as a printed publication as required under U.S. patent law in 35 U.S. Code 102(b). The paper had been placed on a server, but solely to facilitate peer review and it could not be accessed by the researching public.8 Holding that the paper was therefore not prior art, the court vacated a summary judgment of invalidity against the patents.

A factor that may simplify and facilitate activity with SSOs is that U.S. patent law has recently changed. In switching the United States from a first-toinvent to a first-inventor-to-file priority system for patent applications filed on or after March 16, 2013, the America Invents Act of 2011 has ostensibly moved U.S. patent law in the direction of European law and other international patent systems. This should make published standards documents in one jurisdiction more translatable to use in other jurisdictions than in the past. Further actions toward harmonizing the requirements for prior art standards publications might be useful, although the process of harmonizing substantive patent laws is inherently difficult and often protracted.

A second issue raised in discussions of prospects for USPTO-SSO cooperation is whether it is appropriate for USPTO to take membership in private organizations, an element of the EPO’s relationship with the ITU and ETSI, but not IEEE-SA. Although a number of federal government agencies participate as members in organizations such as the American National Standards Institute (ANSI), the USPTO no longer participates, considering an arm’s-length relationship to be the appropriate way for a regulatory agency to support the private sector standards development system while avoiding potential conflicts of interest. Membership may contribute to a certain level of trust in the EPO’s relationships with ITU and ETSI, but it is the process of arriving at the MOUs, benefiting from them, and maintaining them that fosters a belief that they are strategic assets.

Along this line, it should also be recognized that U.S. federal and state governments, like governments in other countries,9 play a significant role as a purchaser of standardized products (DeNardis, 2012). Accordingly, government agencies have an interest in robust, accessible standards that promote interoperability, cost-efficiency, innovation, transparency in the inclusion of technologies in standards, and a diverse system in which no single company controls the standard or is its sole implementer.10 Cooperation between the USPTO and SSOs could contribute to these objectives.

7.5 Recommendations to the USPTO and SSOs

The committee finds that the EPO’s information sharing arrangements with leading international SSOs have demonstrated their value to both parties of having broad, timely, and low-cost access to standards prior art with important potential gains in transparency and efficiency. Similar arrangements could achieve such gains also for the United States even if U.S. law more narrowly circumscribes the range of standards documentation that qualifies as prior art. It should be possible for leading SSOs to agree on terms of cooperation with the USPTO that enable mutually beneficial information sharing without raising concerns about conflicts of interest.

Recommendation 7:1

First, in the wake of the passage and implementation of the America Invents Act, the USPTO should

  • Clarify how the legal definition of prior art varies across jurisdictions, particularly as between the EPO and USPTO. Specifically, when is art “publicly available” in a standards context?
  • Explore with leading SSOs, including possibly ETSI, IEEE-SA and ITU, information sharing arrangements similar to those concluded by the EPO;
  • Work with other patent offices to establish uniform fields and templates for standards-based prior art documents, such as early drafts of specifications, published minutes, and the like, and deliberate with other offices on the definition of sharable information in this context;
  • Improve standards technology education for U.S. patent examiners. For example, when standards developers convene in Washington, they could be asked to instruct and update USPTO examiners about standards processes and recent developments; and
  • Develop joint education programs with SSOs on the pros and cons of standards-based prior art, especially early drafts, and benefits from including it in patent office search databases.

Patent Challenges for Standard-Setting in the Global Economy: Lessons from Information and Communication Technology examines how leading national and multinational standard-setting organizations (SSOs) address patent disclosures, licensing terms, transfers of patent ownership, and other issues that arise in connection with developing technical standards for consumer and other microelectronic products, associated software and components, and communications networks including the Internet. Attempting to balance the interests of patent holders, other participants in standard-setting, standards implementers, and consumers, the report calls on SSOs to develop more explicit policies to avoid patent holdup and royalty-stacking, ensure that licensing commitments carry over to new owners of the patents incorporated in standards, and limit injunctions for infringement of patents with those licensing commitments. The report recommends government measures to increase the transparency of patent ownership and use of standards information to improve patent quality and to reduce conflicts of laws across countries.
