Patent Thicket Avoidance: PTO Proposes Changes to Terminal Disclaimer Practice

by | May 23, 2024 |

On May 10, 2024, the US Patent & Trademark Office (PTO) issued a notice of proposed rulemaking (Notice) concerning major changes to the terminal disclaimer (TD) practice, which may lead to a sea change in patent prosecution strategies. The proposed change would require a TD to include an agreement from the patent owner that the patent will be unenforceable if it’s tied directly or indirectly to another patent having any patent claim invalidated or canceled based on prior art. 89 Fed. Reg. 40439 (May 10, 2024).

The rule change is a potential boon for patent challengers and is intended to promote innovation and competition by allowing a competitor to avoid enforcement of patents tied by TDs to patents with claims finally held unpatentable or invalid. Under current practice, invalidation of a patent tied to another patent by a TD does not directly affect the patentability of the other patent. Under the new rule, a competitor could target a single patent in a validity dispute in a post-grant challenge without the need to seek review and invalidation of other related patents. As a result, invalidating one claim in a patent tied to other patents by TDs would render all other tied patents unenforceable.

According to the Notice, the proposed change aligns with the US government’s intent to reduce drug costs and promote competition by reducing barriers to market entry in accordance with President Biden’s Executive Order 14036 on “Promoting Competition in the American Economy.” Part of the reduced costs are said to come from bringing down the cost of challenging large “patent thickets” of multiple patents covering a single product or minor variations of the product tied by TDs.

The proposed rule change would represent a paradigm shift for TD practice. Current TD practice under 37 CFR 1.321(c) or (d) allows applicants to file multiple patents with claims varying in only minor ways from one another by filing TDs to obviate obviousness-type double patenting (ODP) rejections over closely related patent claims issued or pending in applications commonly owned or commonly owned on the basis of a joint research agreement. In filing a TD, the applicant agrees to disclaim any patent term extending beyond the term of the prior patent having similar patent claims.

The proposed rule seeks “to revise 37 CFR 1.321 (c) and (d) to require that a terminal disclaimer filed to obviate nonstatutory double patenting include an agreement by the disclaimant that the subject patent or any patent granted on the subject application shall be enforceable only if the patent is not tied and has never been tied directly or indirectly to a patent by one or more terminal disclaimers filed to obviate nonstatutory double patenting in which:

(1) any claim has been finally held unpatentable or invalid under 35 U.S.C. 102 or 103 . . . by a Federal court in a civil action or by the PTO, and all appeal rights have been exhausted; or

(2) a [...]

Clean Up on Aisle PTAB: Clarification of Discretionary Denial Practice

by | May 2, 2024 |

The US Patent & Trademark Office (PTO) issued a Notice of Proposed Rulemaking (NPRM) for inter partes review (IPR) and post-grant review (PGR) proceedings before the Patent Trial & Appeal Board, seeking to codify existing precedent and guidance regarding the Board’s discretionary considerations in denying IPR or PGR petitions. 89 Fed. Reg. 28693 (Apr. 19, 2024).

The NPRM follows a 2020 request for comments and an April 2023 Advance Notice of Proposed Rulemaking (ANPR) that the PTO had hoped to finalize in terms of rulemaking by fall 2023. However, proposals in the ANPR hit a snag following criticism from Congress and more than 14,500 comments from stakeholders and the public, including charges that the PTO Director was overstepping her authority.

The newly proposed rules address:

  • Briefing on motions for discretionary denial
  • Factors for discretionary denial
  • Termination and settlement agreements

Briefing on Motions for Discretionary Denial

A significant aspect of the proposal provides for a separate briefing schedule between a patent owner’s preliminary response (POPR) and a request for discretionary denial, which must be filed no later than one month prior to the deadline for the POPR for briefing on its merits. Under the proposal, the discretionary denial arguments would be excluded from the preliminary response unless otherwise authorized by the Board and are intended to avoid encroaching on the wordcount limits for briefing on the merits. Under the proposed briefing process, there would be a 10-page limit for a patent owner’s request for discretionary denial and for the petitioner opposition, and a five-page limit for the patent owner’s sur-reply.

Factors for Discretionary Denial

The proposed rules address denial of institution for “parallel petitions” or “serial petitions” to provide a framework for considering whether previously presented art or arguments provide grounds for denial. The proposed rules also address treatment of joinder petitions, particularly in relation to already instituted petitions. Parallel petitions are defined in the proposed rule as two or more petitions by the same petitioner challenging the same patent that are filed on or before the filing of a POPR to any of the petitions or on or before the due date for filing a POPR to the first petition. Serial petitions are defined as challenged claims of the same patent overlapping with those in a previously filed petition for IPR, PGR or covered business method patent review.

According to the proposed rules, a parallel petition would not be instituted without a good cause showing of why more than one petition is necessary. Factors for a good cause showing include:

  • A petitioner’s ranking of desired petitions for consideration
  • An explanation of differences and materiality between the petitions
  • The number of challenged patent claims, including those asserted by the patent owner in district court litigation
  • A priority date dispute
  • Alternative claim constructions requiring different prior art references on mutually exclusive grounds
  • Knowledge of asserted claims at the time of filing a petition
  • Complexity of the technology

Similar considerations would also apply to joinder petitions.

PTO Proposes New Guidelines for Director Review in Board Proceedings

by | Apr 25, 2024 | ,

The US Patent & Trademark Office (PTO) proposed new rules governing the process for Director review of Patent Trial & Appeal Board decisions in America Invents Act (AIA) proceedings. Rules Governing Director Review of Patent Trial and Appeal Board Decisions, 89 Fed. Reg. 26,807 (proposed Apr. 16, 2024) (to be codified at 37 C.F.R. pt. 42).

The Notice of Proposed Rulemaking (NPRM) proposes adding 37 C.F.R. § 42.75, which includes rules addressing the following issues:

Limited Availability of Director Review. The NPRM proposes that Director review in AIA proceedings would only be available to a party from institution decisions, final written decisions or panel decisions granting rehearing of a decision on institution or a final written decision. However, the Director would have authority to review any interlocutory decisions rendered in reaching such decisions. The NPRM also proposes that the Director may sua sponte review institution decisions, final written decisions or decisions granting rehearing.

Timing, Format and Content of Requests for Director Review. The NPRM proposes that requests for Director review would have to be sought within the time period set forth by 37 C.F.R. § 42.71(d), comply with the formatting and length requirements of 37 C.F.R. §§ 42.6(a) and 42.24(a)(1)(v), and would not be allowed to introduce new evidence. Any sua sponte Director review would have to be initiated within 21 days after the deadline to seek rehearing.

Effect of Director Review. The NPRM proposes that a decision on institution, a final written decision or a decision granting rehearing would become final agency action unless Director review was timely sought or timely initiated sua sponte or a request for Director review was denied.

Director Review Process. The NPRM proposes that Director review would not stay the underlying proceeding, but if the Director grants review, the review would conclude with the issuance of a decision or order that provides the reasons for the Director’s disposition of the case. A party would be permitted to appeal a Director review decision of either a final written decision or a decision granting rehearing of a final written decision (not institution decisions or decisions granting rehearing of institution decisions) to the Federal Circuit in accordance with the procedures set forth in 35 U.S.C. §§ 141(c) and 319. A request for Director review would be treated as a request for rehearing and would reset the time for appeal until Director review was resolved.

Delegation. The NPRM proposes that delegation of Director review would be permitted, subject to conditions set forth by the Director.

Communications With the PTO. The NPRM proposes that communications from a party concerning a specific Director review request or proceeding would have to copy counsel for all parties. Other than authorized amicus briefings, communications from third parties would not be allowed.

Comments are due by June 17, 2024, and can be submitted through the federal eRulemaking portal here.

New Guidance Addresses Use of AI Systems, Tools in Practice Before the PTO

by | Apr 18, 2024 |

The US Patent & Trademark Office (PTO) issued new guidance on the use of artificial intelligence (AI) tools in practice before the PTO. The new guidance is designed to promote responsible use of AI tools and provide suggestions for protecting practitioners and clients from misuse or harm resulting from their use. This guidance comes on the heels of a recent memorandum to both the trademark and patent trial and appeal boards concerning the applicability of existing regulations addressing potential misuse of AI  and recent guidance addressing the use of AI in the context of inventorship.

Patent practitioners are increasingly using AI-based systems and tools to research prior art, automate the patent application review process, assist with claim charting, document reviews and gain insight into examiner behavior. The PTO’s support for AI use is reflected in patent examiners’ utilization of several different AI-enabled tools for conducting prior art searches. However, because AI tools are not perfect, patent practitioners are potentially vulnerable to misuse or misconduct. Therefore, the PTO’s new guidance discusses the legal and ethical implications of AI use in the patent system and provides guidelines for mitigating the risks presented by AI tools.

The guidance discusses the PTO’s existing rules and policies for consideration when applying AI tools, including duty of candor, signature requirement and corresponding certifications, confidentiality of information, foreign filing licenses and export regulations, electronic systems’ policies and duties owed to clients. The guidance also discusses the applicability of these rules and policies with respect to the use of AI tools in the context of document drafting, submissions, and correspondence with the PTO; filing documents with the PTO; accessing PTO IT systems; confidentiality and national security; and fraud and intentional misconduct.

AI tools have been developed for the intellectual property industry to facilitate drafting technical specifications, generating responses to PTO office actions, writing and responding to briefs, and drafting patent claims. While the use of these tools is not prohibited, nor is there any obligation to disclose their use unless specifically requested, the guidance emphasizes the need for patent practitioners to carefully review any AI outputs generated before signing off on any documents or statements made to the PTO. For example, when using AI tools, practitioners should make a reasonable inquiry to confirm that all facts presented have evidentiary support, that all citations to case law and other references are accurately presented, and that all arguments are legally warranted. Any errors or omissions generated by AI in the document must be corrected. Likewise, trademark and Board submissions generated or assisted by AI must be reviewed to ensure that all facts and statements are accurate and have evidentiary support.

While AI tools can be used to assist or automate the preparation and filing of documents with the PTO, care must be taken to ensure that no PTO rules or policies are violated and that documents are reviewed and signed by a person, not an AI tool or non-natural person. AI [...]

PTO Stands by Patent Fee Increases

by | Apr 11, 2024 |

The US Patent & Trademark Office (PTO) issued a notice of rulemaking announcing proposed patent fee increases beginning next year. 89 Fed. Reg. 23226 (April 3, 2024). The proposed increases are generally consistent with the PTO’s May 2023 proposal.

The Notice states that the PTO needs the proposed fee adjustments to provide sufficient revenue to recover costs of patent operations in future years. To that end, the PTO proposes to set or adjust 455 patent fees, including 73 new fees. Complete information about the fee adjustments, including the Notice, is available on the PTO’s website.

The fee increases include higher amounts for routine fees necessary to obtain a patent, including filing, search, examination and issue fees. Excess claim fees will also increase to $200 for each claim over 20 and $600 for each independent claim over three. There will also be an escalating fee structure for terminal disclaimers, ranging from $200 if filed before the first office action to $1,400 if filed after the PTO grants the patent. The fees for filing requests for continued examination (RCE) will now use a tiered fee structure and will increase to $1,500 for the first RCE, $2,500 for the second RCE and $3,600 for the third RCE. Patent Trial & Appeal Board fees will increase by about 25%, and a new fee of $400 will be required for a Request for Director Review of a Board decision.

Written comments on proposed patent fees must be submitted by June 3, 2024, through the Federal eRulemaking Portal.

PTO Proposes Trademark Application Filing Changes, Fee Adjustments

by | Apr 4, 2024 |

On March 26, 2024, the US Patent & Trademark Office (PTO) issued a notice of proposed rulemaking in the Federal Register concerning changes to trademark application filings and fee adjustments in trademark cases for 2025. The PTO solicits written comments from the public on the proposed rule changes on or before May 28, 2024. The proposed rules seek to generate sufficient multiyear revenue for trademark operations in future years based on projections described in the notice.

The changes are recommended to support the PTO’s strategic goals and objectives, including optimizing trademark application pendency through the promotion of efficient operations and filing behaviors, issuing accurate and reliable trademark registrations, and encouraging access to the trademark system for stakeholders.

The proposal seeks to incentivize more complete and timely filings, improve prosecution, adjust 31 trademark fees and impose 12 new fees while discontinuing six existing fees. The proposal also seeks to consolidate the present Trademark Electronic Application System (TEAS) filing options (i.e., TEAS Plus and TEAS standard) into a single electronic filing option. The single option would include most of the same requirements as TEAS Plus, while eliminating those under TEAS Standard. The new filing framework would discontinue the previous filing fees and fees for failing to meet the requirements of a TEAS Plus application. Similar to TEAS Plus, however, applicants complying with the proposed requirements in their initial filing would pay the lowest fees.

The proposed fee adjustments would:

  • Set the fee for a base application at $350 using the ID Master List (which is $100 more than the current fee for a TEAS Plus application)
  • Discontinue current fees for filing an application under the Madrid Protocol
  • Require surcharge fees between $100 and $200 for applications that are noncompliant with the base filing requirements
  • Require an additional $200 fee per class for the identification of goods and services entered in the free-form text field to incentivize use of the Trademark ID Manual for such identifications instead
  • Require an additional $200 fee for each additional group of 1,000 characters in the free-form text field; identifications directly from the ID Manual would not incur these fees
  • Increase fees by $50 for filing amendments to allege use (AAU) and statements of use (SOU), with fees being discounted $100 for electronic filings
  • Increase post-registration maintenance fees from $50 to $75
  • Increase the letter of protest fee from $50 to $150.

Regarding the proposed fee adjustments, the notice describes changes to 37 CFR 2.6 and 7.6. The notice further describes changes to 37 CFR 2.22 and 2.71 with respect to base application fees and amendments to correct informalities, respectively.

For further details, see the Federal Register notice.

PTO to Patent Examiners: Make Interpretation of Means-Plus-Function Claims Clear in the Record

by | Mar 28, 2024 |

On March 18, 2024, the US Patent & Trademark Office (PTO) issued a memorandum to patent examiners addressing means-plus-function and step-plus-function claim limitations and how to clearly articulate, in the prosecution record, the PTO’s interpretation of such claim limitations. The goal of the memorandum is to ensure consistency in connection with the examination of such limitations, provide both the applicant and the public with notice regarding the claim interpretation used by the patent examiner, and provide the applicant an opportunity to advance a different claim interpretation early in the prosecution.

As stated in 35 U.S.C. §112(f), “[a]n element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.” The memorandum does not suggest any changes in interpretation of the statute.

One aspect of the memorandum is to remind examiners of the resources and guidance available when examining means-plus-function and step-plus-function claim limitations, specifically MPEP §§ 2181-2187 and refresh training. In accordance with the guidance, the primary steps when examining such claim elements include:

  • Determining whether a claim limitation invokes § 112(f)
  • Ensuring the record is clear with respect to invoking § 112(f)
  • Evaluating the description necessary to support a § 112(f) claim limitation under §§ 112(a) and (b).

To determine whether a claim limitation invokes §112(f), the guidance instructs examiners to employ the three-prong analysis set forth in MPEP § 2181, subsection I. Using this analysis, recitation of the terms “means” or “step” in association with functional language, rather than structure, material or acts for performing that function, should be interpreted as claim limitations invoking § 112(f). However, where these terms are accompanied by structure, materials or acts for performing the function, § 112(f) is not invoked. On the other hand, a limitation reciting functional language along with a generic placeholder term instead of “means,” which fails to recite sufficiently definite structure for performing the function, would nonetheless invoke § 112(f), according to a proper analysis. Examples of such generic placeholders include “mechanism for,” “module for,” “device for,” “unit for,” “component for,” “element for,” “member for,” “apparatus for,” “machine for” and “system for.”

An important caveat in the memorandum states that “[e]stablishing the interpretation of § 112(f) limitations in writing during prosecution is critical in supporting the agency goal of establishing a clear prosecution record.” The guidance advises examiners that form paragraphs are available in support of meeting this objective, which serve to inform “the applicant, the public, and the courts . . . as to the claim construction the examiner used during prosecution. This further informs the applicant, the public, and the courts (and the PTO for any post-grant review procedures) as to how the examiner searched and applied prior art based on the examiner’s interpretation of the claim.”

The memorandum further emphasizes the need to [...]

New PTAB Claim Construction? Give the Parties Review Opportunity

by | Mar 28, 2024 |

The US Patent & Trademark Office (PTO) Director vacated Final Written Decisions issued by the Patent Trial & Appeal Board that presented a sua sponte construction of a claim term in dispute, holding that the parties were not provided adequate notice of the Board’s new construction. Assa Abloy AB v. CPC Patent Technologies Pty., Ltd., IPR2022-01006, -01045, -01089 (PTAB Decision Review Mar. 15, 2024) (Vidal, PTO Dir.)

The Board issued Final Written Decisions in three inter partes reviews (IPRs), holding that the petitioner failed to demonstrate that any of the challenged claims were unpatentable. The petitioner requested Director Review, raising three issues concerning the Final Written Decisions’ treatment of the claim term “biometric signal”:

  1. The Board’s construction newly added a limitation that neither the petitioner nor the patent owner proposed
  2. The Board’s construction was erroneous
  3. The Board inconsistently addressed this claim limitation among the IPRs at issue.

The Director decided that review was appropriate.

The Director explained that in view of the petitioner’s and patent owner’s divergent post-institution positions regarding this limitation, the Board had authority to construe “biometric signal” even though its institution decisions indicated that the Board would give this claim term its plain and ordinary meaning. The petitioner argued that the term meant “the input and output of the biometric sensor,” and the patent owner argued that the term meant a “physical attribute of the user” (i.e., a fingerprint, facial pattern, iris, retina or voice). The Board held that it meant “a physical or behavioral biometric attribute that provides secure access to a controlled item.”

The Director vacated and remanded the Final Written Decisions, explaining that the Board failed to provide the petitioner and the patent owner reasonable notice of its new construction or the opportunity to present arguments concerning it, as required under the Administrative Procedure Act (APA). The Director noted that neither party requested the Board’s inclusion of a construction that required an attribute of the claimed signal to “provide[] secure access to a controlled item” and concluded this was the sort of “difficult to imagine” sua sponte construction that the US Court of Appeals for the Federal Circuit held (in its 2021 decision in Qualcomm v. Intel) lacked sufficient notice if appearing for the first time in a Final Written Decision.

The Director instructed that on remand the Board should authorize the petitioner to file a supplemental briefing that addresses the Board’s construction and its application to the asserted prior art and authorize the patent owner to respond to the petitioner’s supplemental briefing.

The Director also noted that the patent owner’s proposed claim construction in the IPRs was similar to the construction that the Board adopted in its institution decisions in other IPRs challenging two of the patents at issue. In recognition of this situation, the Director also invited the petitioner, in its supplemental briefing, to address the perceived inconsistencies in these claim constructions.

District Court Subpoena Power Plays “Supporting Role” to PTO Rules

by | Mar 21, 2024 |

Addressing the subpoena power of district courts to compel evidence for use in US Patent & Trademark Office (PTO) proceedings, the US Court of Appeals for the Fourth Circuit upheld a district court’s decision (albeit on alternative grounds), holding that district courts’ authority to issue subpoenas in support of PTO proceedings is limited by the PTO Rules of Procedure. Xactware Solutions, Inc. v. Buildxact Software Ltd., Case No. 22-1871 (4th Cir. March 13, 2024) (Gregory, Harris, Floyd, JJ.)

Buildxact, an Australian company, filed a trademark application at the PTO for BUILDXACT. Xactware opposed the BUILDXACT application at the Trademark Trial & Appeal Board and requested to depose three of Buildxact’s officers via video. When Buildxact objected indicating it would only allow written depositions (citing the PTO rules, which state that foreign depositions must be in writing unless the parties stipulate otherwise or the deposing party shows good cause), Xactware subpoenaed Buildxact through service on Buildxact’s default agent – the PTO Director – for an in-person deposition of a Buildxact corporate representative.

Buildxact filed a motion in the district court to quash the subpoena. The district court magistrate judge granted Buildxact’s motion, finding that Buildxact, which has no office, employees, or regular business in or near Virginia, did not have sufficient contacts to qualify as “being within” the district. Xactware moved for a review of the order, but the district court agreed with the magistrate judge’s ruling. Xactware appealed.

Pursuant to 35 U.S.C. § 23, the PTO may establish its own rules for depositions in cases before the Board. Additionally, 35 U.S.C. § 24 grants the “clerk of any United States court for the district wherein testimony is to be taken for use in any contested case in the Patent and Trademark Office” the power to “issue a subpoena for any witness residing or being within such district, commanding him to appear and testify before an officer in such district authorized to take depositions and affidavits.”

Xactware argued that Buildxact is “within” the district because it has an agent designated to receive service of process there (i.e., the PTO Director). The PTO argued that even if Buildxact were “within” the district, the subpoena must still be quashed as the deposition was improper under the PTO rules. The Fourth Circuit agreed, noting that it consequently need not address whether Buildxact was “within” the district or not.

The Fourth Circuit held that the district court lacked the authority to issue a subpoena compelling Buildxact’s deposition because the deposition being sought was prohibited by PTO rules and would not be admissible in any PTO proceeding. Looking at the legislative history, the Fourth Circuit noted that the district court’s subpoena power under § 24 is only available to the extent the courts are empowered to aid the PTO: “Section 24 assigns a supportive role to the district courts to ensure the smooth functioning of the [PTO] procedures.” Moreover, the explicit language of § 24 requires that a district court can only subpoena testimony “for use [...]

Be Cool: Don’t Construe the Construction

by | Mar 21, 2024 |

The US Court of Appeals for the Federal Circuit vacated and remanded a Patent Trial & Appeal Board decision after concluding that the patent owner’s proposed construction would require the parties to construe the construction. CoolIT Systems, Inc. v. Katherine Vidal, Director of the United States Patent & Trademark Office, Case No. 22-1221 (Fed. Cir. March 7, 2024) (Lourie, Bryson, Stark, JJ.) (nonprecedential).

CoolIT Systems owns a patent directed to a system for fluid heat transfer to cool electronic devices. The patent focuses on a heat exchange system comprising various components including a heat sink, a housing member and a compliant member. The patent claims priority from two provisional applications. Asetek Danmark petitioned for inter partes review (IPR) of the patent based on anticipation and obviousness. During the IPR proceeding, the parties disputed the meaning of the term “matingly engaged,” a term introduced in the later provisional application. To preserve validity, CoolIT argued that the term should be construed narrowly to mean “mechanically joined or fitted together to interlock.” Asetek sought a broader construction of “joined or fitted together to make contact,” which would encompass all methods of joining two surfaces.

The Board found both interpretations extreme and partially construed the term as being satisfied when at least a portion of the compliant member fits within the recessed region of the housing member. Despite agreement on the term “mate” to mean “join or fit together,” there was disagreement on the term “engage.” However, the Board did not determine whether “matingly engaged” could encompass forms of engagement beyond fitting.

The Board found that the cited prior art suggested a compliant member fitting the housing, thus rendering the claims obvious. CoolIT appealed. The US Patent & Trademark Office (PTO) intervened after Asetek withdrew from the appeal based on settlement.

CoolIT argued that the Board’s interpretation was flawed, and that the prior art did not meet the requirements of the “matingly engaged” limitation irrespective of the interpretation adopted. CoolIT contended that its proposed construction aligned with the invention’s purpose and properly distinguished between the 2007 and 2011 provisional applications. CoolIT also argued that the compliant member must partition features to control coolant flow, necessitating a specific type of joining or fitting.

In response, the PTO argued that CoolIT’s proposed construction read limitations from the specification into the claim. The PTO contended that neither the claims nor the specification required “interlock” and disputed CoolIT’s interpretation of the 2007 provisional application. The PTO did not propose an alternative construction, however.

The Federal Circuit concluded that “matingly engaged” should properly be construed as “mechanically joined or fitted together,” as that construction accurately reflected the term’s meaning and aligned with arguments presented by both parties. The Court rejected CoolIT’s proposal to add the word “interlock” because it would cause more confusion than clarity, noting that even CoolIT and the PTO still disagreed over what the term “interlock” meant and thus adding that term to the construction would provide little guidance.

The Federal Circuit found that the Board [...]
