Seeing double? Director instructs Board to resolve claim construction pre-institution

by | Jul 2, 2025 |

The acting director of the US Patent & Trademark Office (PTO) vacated and remanded a Patent Trial & Appeal Board decision to institute two inter partes review (IPR) petitions that challenged the same claims. The acting director determined that the two petitions primarily differed with respect to claim construction. In a decision designated as “informative,” he authorized the Board to resolve claim construction pre-institution in view of the Consolidated Trial Practice Guide’s (CTPG) direction that “one petition should be sufficient to challenge the claims of a patent in most situations.” CrowdStrike, Inc. v. GoSecure, Inc., IPR2025-00068; -00070 (PTAB June 25, 2025) (Stewart, Act. Dir.) The PTO designates a decision as informative when it provides “norms on recurring issues, guidance on issues of first impression to the Board, guidance on Board rules and practices, and guidance on issues that may develop through analysis of recurring issues in many cases.”

CrowdStrike submitted two IPR petitions that challenged the same claims of GoSecure’s patent. The Board instituted both IPRs. GoSecure requested director review, asserting that instituting both petitions was an abuse of the Board’s discretion. On review, the acting director determined that the Board abused its discretion in view of the CTPG’s direction.

The acting director concluded that the two petitions did not reflect an exception to the CTPG’s direction. He determined that CrowdStrike’s petitions were primarily distinguished by the constructions applied to a claim term. The acting director explained that the Board should have construed the term at issue prior to granting institution, concluding that the Board’s institution decision amounted to improper expansion of CrowdStrike’s permitted word count and placed a substantial and unnecessary burden on the Board and GoSecure that could raise fairness, timing, and efficiency concerns. The acting director vacated and remanded the Board’s institution decision.

The acting director also instructed the Board that the patent owner should be allowed to “submit whatever arguments are necessary for the panel to make a claim construction determination” even if the patent owner has not addressed the issue.

CRISPR Clarity: Enablement Is Analyzed Differently Under §§ 102 and 112

by | Jun 18, 2025 | ,

In a decision underscoring the distinct standards governing enablement under §§ 102 and 112, the US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board’s finding that a prior art reference was enabling for purposes of anticipation, even in the absence of working examples. Agilent Technologies, Inc. v. Synthego Corp., Case Nos. 23-2186; -2187 (Fed. Cir. June 11, 2025) (Prost, Linn, Reyna, JJ.)

The case centers on CRISPR, the gene-editing technology that has reshaped the frontiers of biology and biotechnology. Agilent owns patents that claim chemically modified guide RNAs (gRNAs) designed to improve stability and performance in CRISPR-Cas systems. Synthego filed an inter partes review (IPR) petition asserting that the patents were unpatentable. The Board found all claims unpatentable, relying on a 2014 publication by Pioneer Hi-Bred that disclosed similar modified gRNAs. Agilent appealed.

Agilent challenged the Board’s finding that the prior art was enabling, arguing that Pioneer Hi-Bred merely proposed a research plan without demonstrating which specific modifications would yield functional gRNAs. Agilent emphasized that the reference lacked working examples and disclosed numerous nonfunctional sequences, contending that a skilled artisan would not have been able to identify a successful embodiment without undue experimentation. It also argued that the nascent state of CRISPR technology in 2014 compounded the unpredictability, making the reference non-enabling. In support, Agilent relied heavily on the Supreme Court’s 2023 decision in Amgen v. Sanofi, where the Supreme Court invalidated a broad genus claim for failing to enable its full scope.

The Federal Circuit was not persuaded. The Court drew a clear distinction between enablement under § 112 (which governs patent validity) and enablement under § 102 (which governs anticipation). The Court explained that the bar is lower for the latter, and that a prior art reference need only enable a single embodiment within the scope of the claim. While Amgen involved § 112, the Court emphasized that this case turned on § 102, where the standard is less demanding.

The Federal Circuit grounded this distinction in both the statutory text and the underlying purpose of the respective provisions. Statutorily, § 112 requires that a patent specification enable a person of ordinary skill in the art to “make and use” the invention. Section 102, by contrast, contains no such requirement. This divergence reflects a difference in purpose: § 112 ensures that the patentee does not claim more than they have taught, thereby preventing overbroad monopolies. As the Supreme Court explained in Amgen, “[t]he more a party claims, the broader the monopoly it demands, the more it must enable.” But the Federal Circuit emphasized that the Supreme Court’s reasoning in Amgen was rooted in the patentee’s burden to support the full scope of a genus claim under § 112. That concern, the Court explained, does not apply in the § 102 context, where the question is not how much the prior art claims, but whether it teaches enough for a skilled artisan to practice at least one embodiment without undue [...]

Speculation of Harm Isn’t Standing: Not Every Adverse Board Decision Is Ticket to Appeal

by | Jun 12, 2025 | ,

After assessing whether a patent owner had standing to appeal the Patent Trial & Appeal Board’s final written decision, the US Court of Appeals for the Federal Circuit found no injury in fact to support Article III jurisdiction and dismissed the appeal. Dolby Labs. Licensing Corp. v. Unified Patents, LLC, Case No. 23-2110 (Fed. Cir. June 5, 2025) (Moore, Clevenger, Chen, JJ.)

Dolby owns a patent covering a prediction method involving an in-loop filter. Unified Patents, claiming to be the sole real party in interest (RPI), filed an inter partes review (IPR) challenging several patent claims as anticipated and obvious. Dolby contested the challenge, identifying nine additional entities it argued should have been named as RPIs (alleged RPIs). The Board declined to rule on Dolby’s inclusion, however, and proceeded with Unified as the sole RPI.

In its final written decision, the Board found that Unified failed to establish the unpatentability of any challenged claims. Consistent with the US Patent & Trademark Office’s practice, it also declined to address the RPI dispute, finding it immaterial – there was no evidence the alleged RPIs were estopped from filing their own IPRs later or that Unified had advantageously or strategically omitted them. Dolby appealed.

The Federal Circuit explained that when it reviews final Board decisions, its jurisdiction is constrained by Article III’s “Cases” and “Controversies” requirement. To establish standing, an appellant must demonstrate:

  • A concrete and particularized injury in fact that is actual or imminent, not speculative.
  • A causal link between the injury and the appellee’s challenged conduct.
  • A likelihood that the injury will be redressed by a favorable ruling.

Dolby asserted standing to appeal the Board’s refusal to address the RPI dispute based on three grounds:

Its statutory right to appeal as a “dissatisfied” party under 35 U.S.C. § 319.

  • The denial of its right to information under 35 U.S.C. § 312(a)(2).
  • An injury in fact arising from potential breaches of license agreements by the alleged RPIs and possible conflicts of interest involving the Board’s administrative patent judges.

The Federal Circuit rejected Dolby’s argument that it had a right to appeal based solely on dissatisfaction with the Board’s decision. The Court explained that the right to appeal a Board decision under the America Invents Act (AIA) requires Article III standing. The Court also dismissed Dolby’s argument for a statutory right to RPI information, finding that the AIA does not create an informational right. The Court explained that unlike statutes such as the Federal Advisory Committee Act or the Federal Election Campaign Act, which expressly grant public access to information, the AIA lacks a public access provision and explicitly limits judicial review of IPR-related determinations, including RPI disclosures.

As to Dolby’s right to appeal the Board decision, the Federal Circuit found Dolby’s argument too speculative to establish standing, citing four key deficiencies:

Dolby failed to assert that any alleged RPIs were party to license agreements, undermining its claim of potential breach.

X-Ray Vision: Court Sees Through Implicit Claim Construction

by | Jun 5, 2025 |

The US Court of Appeals for the Federal Circuit reversed the Patent Trial & Appeal Board’s final determination that challenged patent claims were not unpatentable, finding that the Board’s decision relied on an erroneous implicit claim construction. Sigray, Inc. v. Carl Zeiss X-Ray Microscopy, Inc., Case No. 23-2211 (Fed. Cir. May 23, 2025) (Dyk, Prost, JJ.; Goldberg, Chief Distr. J., sitting by designation).

Zeiss owns a patent related to X-ray imaging systems that incorporate projection magnification. Sigray filed a petition requesting inter partes review (IPR) of all claims in the patent. After institution, the Board issued its final written decision, which declined to hold any of the challenged claims unpatentable. Sigray appealed.

On appeal, Sigray argued that the claims were unpatentable based on a single prior art reference, Jorgensen. The Jorgensen reference “describes a system that uses an X-ray source to generate an X-ray beam, which then passes through a sample before being received by a detector.” Sigray argued that Jorgensen anticipated or rendered the challenged claims obvious. The parties agreed that Jorgensen explicitly disclosed all the limitations of the independent claim except for one reading “a magnification of the projection X ray stage . . . between 1 and 10 times.”

The parties’ arguments centered on whether the magnification limitation was inherently disclosed in Jorgensen. The Board concluded that “viewing the record as a whole, . . . [Sigray] has not shown persuasively that Jorgensen inherently discloses projection magnification within the claimed range. Sigray argued, and the Federal Circuit agreed, that the Board’s findings incorrectly relied on a flawed understanding of the claimed range. In Sigray’s view, “the Board implicitly and incorrectly construed the limitation ‘between 1 and 10’ to exclude unspecified, small divergence resulting in projection magnifications only slightly greater than 1.” This was illustrated by the Board’s determination that Sigray “failed to show that the . . . X-ray beam in Jorgensen diverges enough to result in projection magnification between 1 and 10 times.”

The Federal Circuit found that the Board’s use of the term “enough” indicated that the evidence it relied on supported a finding of some divergence in the X-ray beams. Because the beams were not completely parallel, the Court reasoned that some magnification necessarily resulted, and that even a miniscule amount (as disclosed in the prior art) fell within the claimed magnification range of 1 to 10. Since the Board made only one evidence-supported finding relevant to anticipation, the Court reversed on the independent claim and two dependent claims without remand. However, the Court remanded the case to the Board to determine whether the three remaining challenged claims, which recited further material limitations, would have been obvious.

Clickbait: Actual Scope (Not Intended Scope) Determines Broadening Reissue Analysis

by | May 15, 2025 |

The US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board’s rejection of a proposed reissue claim for being broader than the original claim, denying the inventors’ argument that the analysis should focus on the intended scope of the original claim rather than the actual scope. In re Kostić, Case No. 23-1437 (Fed. Cir. May 6, 2025) (Stoll, Clevenger, Cunningham, JJ.)

Miodrag Kostić and Guy Vandevelde are the owners and listed inventors of a patent directed to “method[s] implemented on an online network connecting websites to computers of respective users for buying and selling of click-through traffic.” Click-through links are typically seen on an internet search engine or other website inviting the user to visit another page, often to direct sales. Typical prior art transactions would require an advertiser to pay the search engine (or other seller) an upfront fee in addition to a fee per click, not knowing in advance what volume or responsiveness the link will generate. The patent at issue discloses a method where the advertiser and seller first conduct a trial of click-through traffic to get more information before the bidding and sale process. The specification also discloses a “direct sale process” permitting a seller to bypass the trial and instead post its website parameters and price/click requirement so advertisers can start the sale process immediately.

The independent claim recites a “method of implementing on an online network connecting websites to computers of respective users for buying and selling of click-through traffic from a first exchange partner’s web site.” The claim requires “conducting a pre-bidding trial of click-through traffic” and “conducting a bidding process after the trial period is concluded.” A dependent claim further requires “wherein the intermediary web site enables interested exchange partners to conduct a direct exchange of click-through traffic without a trial process.”

The patent was issued in 2013, and the inventors filed for reissue in 2019. The reissue application cited an error, stating that the “[d]ependent claim [] fails to include limitations of [the independent] claim,” where the dependent claim “expressly excludes the trial bidding process referred to in the method of [the independent] claim,” which would render it invalid under 35 U.S.C. § 112. To fix the error, the inventors attempted to rewrite the dependent claim as an independent claim that omitted a trial process.

The examiner issued a nonfinal Reissue Office Action rejecting the reissue application as a broadening reissue outside of the statutory two-year period. The examiner found that the original dependent claim is interpreted to require all steps of the independent claim, including the trial period, and further to require a direct sale without its own trial, beyond the trial claimed in the independent claim. The inventors attempted to rewrite the dependent claim as the method of independent claim with “and/or” language regarding the trial process versus direct to sale process. The amendment was rejected for the same reasons. The Board affirmed on appeal.

Whether amendments made during reissue enlarge the scope of [...]

No Article III Appellate Standing Under the Sun

by | May 15, 2025 |

The US Court of Appeals for the Federal Circuit dismissed Incyte’s appeal of a Patent Trial & Appeal Board decision, holding that a disappointed validity challenger lacked appellate standing to challenge the Board’s final written decision. Incyte Corp. v. Sun Pharmaceuticals Industries, Inc., Case No. 23-1300 (Fed. Cir. May 7, 2025) (Moore, C.J.; Hughes, Cunningham, JJ.) (Hughes, J., concurring).

After the Board upheld the validity of challenged claims of a patent owned by Sun Pharmaceuticals in a post-grant review proceeding (PGR), Incyte appealed and sought a determination that the claims were unpatentable. Sun Pharmaceuticals challenged whether Incyte had Article III standing to support an appeal to the Federal Circuit based on a lack of injury-in-fact.

The Federal Circuit focused on its jurisdiction to hear the appeal as a threshold issue and whether Incyte, as the party seeking review, met its burden of establishing Article III standing at the time it filed its appeal.

As context, the Federal Circuit noted that standing requires a concrete, actual, or imminent injury that is traceable to the challenged conduct and likely to be redressed by the court’s decision. Incyte asserted it had standing to appeal based on potential infringement liability and under the competitor standing doctrine.

Addressing potential infringement liability, the Federal Circuit noted Incyte’s reliance on a supplemental declaration from an in-house business development leader submitted during briefing. Noting that Incyte’s Article III standing was “not self-evident,” the Court ruled that Incyte should have presented evidence prior to its reply brief and declined to consider the supplemental evidence. Incyte was on notice that its appellate standing was challenged, and that evidence of its standing should have been submitted at the earliest possible opportunity. Finding no good cause for the delay, the Court declined to exercise its discretion to consider Incyte’s supplemental evidence and, based only on earlier submitted evidence, found that Incyte failed to establish that it had “concrete plans for future activity” that would create a “substantial risk of future infringement.”

In its discussion of the competitor standing doctrine, which allows competitors to challenge patents that could harm their competitive position, the Federal Circuit found the doctrine inapplicable because Incyte failed to show it would suffer economic harm from the Board’s ruling on patent validity. Rather, the Board’s ruling upholding specific patent claims “does not, by the operation of ordinary economic forces, naturally harm a [challenger] just because it is a competitor in the same market as the beneficiary of the government action (the patentee).” As the Court explained, “it is not enough to show a benefit to a competitor to establish injury in fact; the party seeking to establish standing must show a concrete injury to itself.”

The Federal Circuit held that because Incyte had not shown it was currently engaged in or had non-speculative plans to engage in conduct covered by the challenged patent, it was unable to establish injury-in-fact.

In his concurrence, Judge Hughes stated that while Incyte lacked Article III standing, he believed that Federal Circuit precedent was [...]

New Administration, Same Patent Reform Bill

by | May 8, 2025 |

A bipartisan group of senators and congressional representatives reintroduced the Patent Eligibility Restoration Act (PERA), which aims to reform the law of patent eligibility under 35 U.S.C. § 101. PERA seeks to address the challenges posed by recent Supreme Court decisions and restore clarity and predictability in the US patent system.

PERA preserves the existing categories of subject matter currently enumerated in § 101 but adds several categories of excluded subject matter. PERA proposes to eliminate all judicial exceptions to patent eligibility, specifying that certain categories, such as mathematical formulas that are not part of an invention, processes that a human could perform, mental processes, unmodified human genes, and unmodified natural material, are not eligible for patents.

A separate bipartisan group of senators and congressional representatives reintroduced the Promoting and Respecting Economically Vital American Innovation Leadership (PREVAIL) Act, which aims to protect and increase the value of US intellectual property rights by making significant reforms to the Patent Trial & Appeal Board.

PREVAIL seeks to limit Board challenges to entities that have been sued or threatened with a patent infringement lawsuit, close the statutory bar joinder loophole to prevent time-barred entities from joining instituted inter partes review (IPR) proceedings, and prevent serial petitions by applying estoppel at the time the challenge is filed instead of when the Board issues its final written decision.

Transatlantic Terminology: Skilled Artisan Could Equate UK, US Word Meanings

by | Apr 24, 2025 |

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board unpatentability determination, finding that a skilled artisan would have found the term “sterile” in a UK publication to mean the same as the term “sterilized” in the United States. Sage Products LLC v. Stewart, Case No. 23-1603 (Fed. Cir. Apr. 15, 2025) (Reyna, Cunningham, Stark, JJ.)

Sage owns two patents related to a sterilized chlorhexidine product in a package, such as an applicator filled with an antiseptic composition for disinfecting skin. Becton, Dickinson and Company petitioned for inter partes review (IPR) of both patents. The Board relied on four key pieces of prior art, including one that was a UK publication, to find the challenged claims unpatentable. In instituting the IPR and evaluating the petition, the Board construed the term “sterilized” to mean that “the component or composition has been subjected to a suitable sterilization process such that sterility can be validated.” In the final written decision, the Board found that a skilled artisan at the time of the invention would have known, through education and experience, that the term “sterile,” as used in the UK prior art publication, is equivalent to the term “sterilized,” as used in the US and particularly in the Sage patents. Reviewing the totality of the evidence before it, including both parties’ experts’ reports and testimony, the Board determined the challenged claims were unpatentable. Sage appealed.

The Federal Circuit declined to overturn the Board’s findings, affirming the Board’s definition of a person of ordinary skill in the art and their understanding of the term “sterilized” at the time of the invention. The Court found that the Board did not ignore or disregard evidence but properly weighed the evidence before it, concluding that a skilled artisan having the education and experience required by the Board’s definition would know the differences between the US and UK regulatory standards for “sterile” and therefore would know that UK references to “sterile” items would satisfy the challenged claims’ requirement for “sterilized” items.

Fintiv Guidelines for Post-Grant Proceedings Involving Parallel District Court Litigation

by | Apr 3, 2025 |

On March 24, 2025, the US Patent & Trademark Office (PTO) released new guidance that clarifies application of the Fintiv factors when reviewing validity challenges simultaneously asserted at the Patent Trial & Appeal Board and in district court or at the US International Trade Commission.

This guidance follows the PTO’s February 28, 2025, announcement reverting to its previous guidelines for discretionary denials of petitions for post-grant proceedings where district court litigation is ongoing. That announcement rescinded the PTO’s June 21, 2022, memorandum entitled “Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation,” which prevented the Board from rejecting validity challenges where there was “compelling evidence of unpatentability.”

Based on the new guidance, the Board is more likely to defer to the district court or the Commission if the Commission’s projected final determination date is earlier than the deadline for the Board’s final written decision. The PTO pointed out that a patent challenger’s stipulation not to raise the same invalidity arguments in other proceedings if the PTO institutes an inter partes review or post grant review is highly relevant but not dispositive.

This change in policy increases the likelihood that the Board will grant discretionary denials in situations involving parallel district court or Commission proceedings.

Detour Ahead: New Approach to Assessing Prior Art Rejections Under § 102(e)

by | Apr 3, 2025 | ,

The US Court of Appeals for the Federal Circuit established a more demanding test for determining whether a published patent application claiming priority to a provisional application is considered prior art under pre-America Invents Act (AIA) 35 U.S.C. § 102(e) as of the provisional filing date, explaining that all portions of the published patent application that are relied upon by the US Patent & Trademark Office (PTO) to reject the claims must be sufficiently supported in the provisional application. In re Riggs, Case No. 22-1945 (Fed. Cir. Mar. 24, 2025) (Moore, Stoll, Cunningham, JJ.)

Several inventors who work for Odyssey Logistics filed a patent application directed to logistics systems and methods for the transportation of goods from various shippers by various carriers across different modes of transport (e.g., by rail, truck, ship, or air). PTO rejected the application under § 102(e) in view of Lettich, which claimed the benefit of a provisional application (Lettich provisional), and as obvious in view of Lettich in combination with the Rojek reference.

The inventors appealed the Lettich rejections to the Patent Trial & Appeal Board, arguing that Lettich did not qualify as prior art under § 102(e). The Board initially agreed with the inventors, but the Examiner assigned to the application requested a rehearing, asserting that the Board applied the incorrect standard for § 102(e) prior art. The Board ultimately issued its decision on the Request for Rehearing, stating that it had jurisdiction over the Examiner’s request and that the Examiner’s arguments regarding Lettich’s status as prior art under § 102(e) “[we]re well taken.” The Board amended its original decision “to determine that Lettich is proper prior art against the instant claims.” The Board then reviewed and affirmed the Examiner’s anticipation and obviousness rejections. The inventors appealed.

The Federal Circuit vacated and remanded the Board’s decision. With respect to whether Lettich qualified as § 102(e) prior art, the Court found that the Board’s analysis was incomplete. The Court concluded that the Board correctly applied the test set forth in the Federal Circuit’s 2015 decision in Dynamic Drinkware v. National Graphics by determining that the Lettich provisional supported at least one of Lettich’s as-published claims. However, the Court found that this test was insufficient because all portions of the disclosure that are relied upon by the PTO to reject the claims must also be sufficiently supported in the priority document. Although the PTO asserted that the Board had conducted this additional analysis, the Federal Circuit disagreed and vacated and remanded for the Board to determine whether the Lettich provisional supported the entirety of the Lettich disclosure that the Examiner relied on in rejecting the claims.
