D. Ariz.: Failure to mark abolishes past damages (posted 01/21/25)

§ 287(a): “[. . .] In the event of failure so to mark, no damages shall be recovered by the patentee in any action for infringement, except on proof that the infringer was notified of the infringement and continued to infringe thereafter, in which event damages may be recovered only for infringement occurring after such notice.”

In Lighting Defense Group LLC v. Shanghai Sensi Electronic Engineering Co. Ltd. et al. 1), the failure of a licensed third party to mark products as patented triggered 35 U.S.C. § 287. LDG licensed its patent in May of 2020 and argued that opposing party SANSI was liable for infringement prior to that date, i.e., prior any legal requirement to mark. Based on the plain meaning of the statute, the court disagreed.

Federal Circuit Year in Review (posted 01/11/25)

In 2024, the Federal Circuit issued eighteen opinions labeled “precedential” that were related to patent law. Quotations below omit citations and internal quotation marks. Here is a break-down:

Anticipation / Obviousness

Cytiva Bioprocess R&D AB v. JSR Corp.: Non-obviousness of novel compounds

  • Reasonable expectation of success is not needed for motivation to combine for claims directed to an inherent property of an otherwise obvious composition or process.
  • Lead-compound analysis not required when the prior art expressly suggests the modification
  • Obvious to try is obvious under § 103 when there is a design need or market pressure exists to solve the problem and there are a finite number of identified, predictable solutions.

Palo Alto Networks, Inc. v. Centripetal Networks, LLC et al.: Motivation to combine (Patent challenger appeals from unsuccessful IPR.)

  • Patentability determinations based on obviousness must “clearly explain[] its holding or rationale regarding motivation to combine and whether the proposed combination teaches the . . . limitation.”
  • “Arguments that 'attack the disclosures of the two references individually' lack merit.”

Pfizer Inc. v. Sanofi Pasteur Inc.: Optimization of result-effective variables (Patent owner Pfizer challenges IPR holding of invalidity.)

  • If a claimed parameter would have been recognized as result-effective, the optimization of that parameter is normally obvious.

Virtek Vision Internat'l ULC v. Assembly Guidance Systems, Inc.: Motivation (Patent owner Virtek and patent challenger Aligned Vision cross-appeals IPR findings of a subset of challenged claims invalid.)

  • KSR did not do away with the requirement that there must exist a motivation to combine various prior art references in order for a skilled artisan to make the claimed invention. Here, the court quoted KSR stating “when there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense.” However, because the patent challenger failed to articulate any rationale or motivation for combining the references, it was “error of law” for PTAB to conclude that selection of one known coordinate system over another was obvious.

Prior Art

Sanho Corp. v. Kaijet Tech. Int'l Ltd.: Excluding prior art under § 102(b)(2)(B) (Patent owner Sanho appeals invalidity finding by PTAB.)

  • A non-confidential, but otherwise private sale of a product embodying an invention does not qualify as a “public disclosure” for an exemption of prior art under 35 U.S.C. § 102(b)(2)(B).

Weber v. Provisur Tech.: Printed publication requirement. (Patent challenger Weber appeals PTAB holding that Provisur's patents were not invalid.)

  • No minimum number of occasions of access is dispositive of the public accessibility inquiry.
  • It's sufficient to meet public accessibility requirement for a product manual to be obtained (1) upon purchase and (2) upon direct request.”

Design Patents

LKQ Corp. v. GM Global Tech. Operations, LLC: Design Patent Nonobviousness (Patent challenger LKQ appeals PTAB decision upholding GM's design patent on a vehicle front fender.)

  • The court overturned the Rosen-Durling test for obviousness analysis of design patents.

Claim Construction

IOENGINE, LLC v. Ingenico Inc.: Printed matter doctrine (Fed. Cir. reversed PTAB's invalidation of claims related to portable data processing devices.)

  • “Encrypted communications” and “program code” are not claimed for the content they are communicating, therefore they are not “printed matter” and the printed matter doctrine does not apply.

Pacific Biosciences of California, Inc. v. Personal Genomics Taiwan, Inc.: “For identifying a single biomolecule”

  • The PTAB's construction of the phrase, “for identifying a single biomolecule” properly required an apparatus to have the capability to characterize (determine the identity of) a biomolecule by examining that biomolecule alone, with no copies created to form an ensemble for examination.

Written Description

RAI Strategic Holdings v. Philip Morris Products: Claimed ranges (Appeal by patent owner RAI of post-grant review finding invalidity.)

  • A broader range of a variable in the application as filed provides written description support for a narrower claimed range if the disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed range. The court looked to whether the broad described range pertains to a different invention than the narrower (and subsumed) claimed range.

Procedural Determinations

ZyXEL Communications v. Unm Rainforest Innovations: Motion to Amend [MTA] Pilot Program. (ZyXEL appeals PTAB's grant to UNMRI's motion to amend and finding claim 8 nonobvious; UNMRI cross-appeals on other findings.)

  • The MTA Pilot Program is designed to allow reply briefs to address and correct errors.

SoftView LLC v. Apple Inc.: Estoppel (Patent owner SoftView appeals PTAB invalidation of all claims based on estoppel)

  • 37 C.F.R. § 42.73(d)(3)(i) is authorized by 35 U.S.C. § 316(a)(4), and the PTO therefore did not exceed its rulemaking authority in promulgating it.
  • Not patentably distinct is equivalent to substantially the same and goes beyond common law by calling for a comparison between the claims an applicant is obtaining and the finally refused or canceled claim.
  • The Board can employ principles of obviousness under KSR in determining whether a claim is patentably distinct from a prior canceled claim under 37 C.F.R. § 42.73(d)(3)(i).

Cywee Group Ltd. v. ZTE (USA), Inc.: Joint IPR petitioners (Patent owner Cywee appeals IPR decision holding original and proposed amended claims unpatentable.)

  • Where an active party to an IPR patent challenge no longer meaningfully engages in the IPR proceeding by not filing an opposition brief to a motion to amend, a passive party can file an opposition brief to a motion to amend, even where the passive party agreed to assume the primary role only if the active party ceases to participate in the IPR.

Koss Corp. v. Bose Corp.: Mootness/Issue Preclusion

  • Filing a (second) amended complaint does not nullify an interlocutory order, where therefore merges with a court's final judgment.

Platinum Optics Tech. v. Viavi Solutions: Standing (Patent challenger PTOT appeals a final written decision from IPR.)

  • A party does not need Article III standing to appear before an administrative agency, but standing is required once the party seeks review of an agency's final action in a federal court.

Speck v. Bates: Interference - (Junior party Speck appeals PTAB's decision awarding priority to Bates.)

  • A long-standing exception to section 135(b)(1), wherein an applicant can file its claim after the critical period but 'had already been claiming substantially the same invention as the patentee' during the critical period, are not time-barred. The underlying issue is . . . whether amendments to the Bates '591 application after the critical date changed the claims so that they are not substantially the same as the claims before the critical date. The Board denied Specification's motion to dismiss because it found that the later amended claims did not differ materially from the claims in other patents and patent applications Bates owned that were filed prior to the critical date because 'Speck had not directed the Board to a material limitation of the Bates involved claims that is not present in the earlier Bates claims.

Voice Tech v. Unified Patents: Appealing after Request for Rehearing (Patent owner Voice Tech appeals from PTAB finding all challenged claims obvious.)

  • An argument not repeated in a Request for Rehearing is not forfeited: “The regulatory requirement that a rehearing request 'identify all matters the party believes the Board misapprehended or overlooked' . . . simply requires the party to identify the issues it wishes to present for rehearing. . . .”

Administrative Procedure Act

Google LLC v. EcoFactor, Inc.: Claim construction and APA (Fed. Cir. vacated PTAB's claim construction.)

  • The Administrative Procedure Act requires that parties are given notice and an opportunity to address changes in claim interpretation​.
    • “The Board may adopt a claim construction of a disputed term that neither party proposes without running afoul of the APA. The Board, however, cannot, without notice and opportunity for the parties to respond, change theories midstream by adopting a claim construction in its final written description that neither party requested nor anticipated. [. . .] [B]ecause Google had notice of the contested claim construction issues and an opportunity to be heard, the Board's claim construction of Claim 1 did not violate the APA.”

Pfizer Inc. v. Sanofi Pasteur Inc.: Director Review (Patent owner Pfizer challenges IPR holding of invalidity.)

  • Failure to abide by notice-and-comment rulemaking in promulgating Director Review procedures is “harmless” unless a party can show prejudice.

Fed. Cir. defines "predefined" (posted 12/31/24)

In Vivint Inc. v. ADT LLC, the Federal Circuit upheld the PTAB's broad interpretation of the term, “predefined.” Claim 1 specifies, “detecting an entity entering a predefined area based at least in part on camera data.” The IPR panel, in finding that certain claims were anticipated and obvious, determined that “predefined” means “defined in advance” and that the “entire field-of-view of a camera” can be a “predefined area.” Stated the court:

Vivint contends that the Board erred by construing 'predefined area' to 'include whatever the camera sees.' It argues that such a broad construction renders 'entering a predefined area' superfluous. That is incorrect. A camera’s entire field-of-view does not automatically or necessarily correspond to a user’s region of interest. Instead, as the Board explained, 'the term “predefined area,” if applied to a camera’s entire field-of-view, would require the user to set up the camera such that the camera’s entire field-of-view would mark a perimeter [to enter] that corresponds to the user’s region of interest,' for example, by zooming in, panning out, or angling.

PTAB opinion vacated for failing to consider motivation in 103 analysis (posted 12/31/24)

In Palo Alto Networks, Inc. v. Centripetal Networks, LLC et al., the Federal Circuit vacated an IPR opinion for failing to make a finding as to whether there was motivation to combine the references under § 103.

After After Final Consideration Pilot (AFCP 2.0) (posted 12/13/24)

Time to bid a (fond?) farewell to the AFCP program at the Patent Office. IPWatchdog gives us a looking-back and a looking-ahead. Key takeaways include:

After today, applicants will need to revert to prior after-final practice, meaning that typically, only amendments that incorporate allowable subject matter into rejected independent claims (or convert allowable but objected-to dependent claims into independent claims) will be entered.

Intellectual Property as a wealth engine (posted 10/24/24)

Christopher W. Quinn, of Quinn IP Law and also professor of IP innovation and strategy at the University of Michigan, posted a thoughtful article on how IP law is relevant, and some controversial reforms. A worthwhile read!
