The Rising Bar for Patent Experts: Finesse Wireless and the Need for Particularized Precision

Patent

by Dennis Crouch

The Federal Circuit reversed a Texas jury’s $166 million infringement verdict in Finesse Wireless LLC v. AT&T Mobility LLC, 24-1039 (Fed. Cir. Sept. 24, 2025), holding that the patentee’s contradictory and unclear expert testimony could not support the Jury’s finding of patent infringement.  The case is centered on  Finesse’s U.S. Patent Nos. 7,346,134 and 9,548,775, which relate to methods of reducing “intermodulation interference” in wireless communications.

Chief Judge Moore, writing for a unanimous panel, emphasized that when a patentee’s infringement case rests on “self-contradictory testimony” from its expert, courts “may conclude the evidence is insufficient” to satisfy the burden of proof.  But in this case, the panel didn’t just note the possibility of insufficient evidence – it actually applied the rule against the patentee. After analyzing Dr. Wells’s contradictions, the opinion held: “This sort of confusing change of course is not sufficient to support the jury verdict.”

This decision underscores the Federal Circuit’s escalating demands on expert testimony in patent cases. It shows up at two levels: (1) parties must marshal “their” experts to walk the jury through virtually every technical or patent‐law issue; and (2) the expert’s testimony must be internally consistent, tightly tied to the record, and conveyed with particularized precision.  I’ve written on this new hurdle that is typically focused on patentee-presentations.  See Federal Circuit Tightens Expert Testimony Standards in Trudell, Patently-O (Feb. 2025); Throwing Out the Jury: How the Federal Circuit’s ‘Particularized Testimony’ Rule Further Threatens the Doctrine of Equivalents, Patently-O, (May 2025); Wilco v.

Headnote Wars in the AI Space: Thomson Reuters (Westlaw) v. ROSS AI

Patent

by Dennis Crouch

ROSS Intelligence has filed its opening brief in the Third Circuit, challenging Judge Stephanos Bibas's decision that the AI company's use of Westlaw headnotes to train its legal search engine constituted copyright infringement. The case presents fundamental questions about the intersection of copyright law and artificial intelligence training that could significantly impact the development of AI systems across industries. Thomson Reuters Enter. Ctr. GmbH v. Ross Intel. Inc., No. 25-2153 (3d Cir. appeal filed Sept. 2025).

ROSS Intelligence built an AI legal search engine designed to let users ask legal questions in plain English and receive ranked, cited passages from judicial opinions as answers. To train the system, ROSS commissioned 25,000 legal memoranda from LegalEase Solutions, each posing a question and providing multiple ranked answers. Many of the questions were adapted directly from Westlaw headnotes summarize points of law from judicial opinions. These headnote-derived questions served as labeled examples that helped the AI learn how to identify, rank, and distinguish between relevant and irrelevant case passages. Although the headnotes themselves were not displayed to ROSS users, they were incorporated into the training process as inputs, making them central to the copyright infringement dispute between Thomson Reuters (owner of Westlaw) and ROSS.

Judge Bibas' February 2025 decision granted summary judgment in favor of the copyright holder -- finding that Westlaw's headnotes were sufficiently original for copyright protection and that ROSS's use for training did not qualify qualified as fair  use.  The district court certified the copyright questions for immediate interlocutory appeal under 28 U.S.C. § 1292(b), recognizing the novel and difficult nature of the issues presented.

In its newly filed appeal, ROSS presents two issues:

  1. Is a short quote or paraphrase of a judicial holding copyrightable?
  2. Does the fair use doctrine protect ROSS’s internal use of Westlaw’s headnotes in memos that served as training data for an AI legal search engine that produced only non-infringing outputs?

Redefining Patent Utility: The Functional Relationship Test’s Answer to Super-Utility Claims

Patent

by Dennis Crouch

The Federal Circuit recently handed down its decision in Bayer Pharma Aktiengesellschaft v. Mylan Pharmaceuticals Inc., No. 2023-2434 (Fed. Cir. Sept. 23, 2025), focusing on the the claim limitation “clinically proven effective.”  Bayer’s U.S. Patent No. 10,828,310, which claims methods for reducing cardiovascular events in certain patients by administering specific doses of rivaroxaban (2.5 mg twice daily) and aspirin (75-100 mg daily) “in amounts that are clinically proven effective.” Generic manufacturers Mylan, Teva, and Invagen successfully challenged the patent in IPR proceedings — finding the claim term non-limiting.  The Federal Circuit agreed that the term did not provide patentable weight – but through a different analytical path.

Clinically Proven Effective: Contrasting Analytical Approaches

The PTAB concluded “clinically proven effective” was non-limiting, reasoning that because the claims already recited specific dosage amounts (2.5 mg rivaroxaban twice daily and 75-100 mg aspirin daily), the additional characterization of these amounts as “clinically proven effective” was merely redundant. Drawing on Bristol-Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368 (Fed. Cir. 2001), the PTAB found the phrase constituted an “expression of intended result [that] essentially duplicates the dosage amounts recited in the claims.”

On appeal though, the Federal Circuit took a markedly different approach, declining to decide whether “clinically proven effective” was limiting at all. Instead, the court applied the functional relationship test from King Pharms, concluding that even if the phrase were limiting, it constituted a “functionally unrelated limitation” that could not rescue an otherwise anticipated method from unpatentability. The court reasoned that clinical proof of efficacy “in no way transforms the process of taking the drug[s]” at the specified amounts and frequencies, emphasizing that the “the actual method . . . is the same” regardless of subsequent clinical validation.

The Functional Relationship Test from King Pharmaceuticals

In King Pharmaceuticals v. Eon Labs, 616 F.3d 1267 (Fed. Cir. 2010), the Federal Circuit established an important test for determining when additional claim limitations can make an otherwise anticipated method patentable. The case involved patents claiming methods of taking the muscle relaxant metaxalone with food to increase the drug's bioavailability - a practice that was already disclosed in prior art for reducing stomach upset. The patentee argued that adding a step of "informing" patients about the increased bioavailability made the claims novel. The Federal Circuit rejected this argument, holding that the relevant inquiry is whether the additional limitation has a "new and unobvious functional relationship" with the known method. Since informing patients about the drug's benefits "in no way transforms the process of taking the drug with food" and "the actual method . . . is the same" regardless of whether patients are informed, the informing step lacked the required functional relationship. This test prevents patentees from indefinitely extending patent protection over known methods by simply adding instructional, informational, or other functionally unrelated steps that don't change how the method actually works.

Ultra Vires or Policy Discretion? Federal Circuit Now Weighing 5x Discretionary Denial Mandamus

Patent

by Dennis Crouch

Two additional mandamus petitions have joined the Federal Circuit's growing docket challenging the USPTO's 2025 shift toward more restrictive inter partes review (IPR) institution practices under President Trump, bringing the total to five pending cases that collectively test the boundaries of appellate review under 35 U.S.C. § 314(d). The newest petitions are In re HighLevel, Inc. (No. 25-148) and In re SanDisk Technologies, Inc. (No. 25-152).  Both challenge Director Stewart expanded discretionary denial approach that rescinded the Vidal memo that petitioners had previously relied upon. HighLevel challenges the USPTO's categorical use of § 101 district court rulings to deny IPR institution for §§ 102/103 challenges, while SanDisk attacks the agency's invocation of "settled expectations" and resource management concerns to deny institution despite litigation stays and Sotera stipulations limiting claim scope overlap.  Prior Patently-O Posts:

The Federal Circuit has requested responses from both the USPTO and IPR petitioners in all five cases (including the earlier In re SAP America, Inc., In re Motorola Solutions, Inc., and In re Google LLC petitions).  This is an unusual step that the court often skips in mandamus practice and signals at least some judicial interest in the underlying legal issues.

Each petition attempts to characterize the USPTO's February 28, 2025 rescission of the Vidal Memo and subsequent policy implementations as constitutional violations or ultra vires agency action.

Welcome New USPTO Director John Squires

Patent

by Dennis Crouch

John A. Squires was confirmed as USPTO Director on September 17, 2025. The Senate voted to confirm Squires using the “nuclear option” – although he received strong bipartisan support in the Judiciary Committee (20-2).  Squires is a longtime patent attorney with experience in many aspects of the IP system: prosecution, litigation, licensing and deals, management, etc.  He has a chemistry background prior to law school, and also worked for many years in fintech – the same field as Commerce Secretary Howard Lutnick.

Squires’ confirmation testimony was largely down-the-middle with his core priorities:

  1. Addressing the application backlog;
  2. Improving quality with “Born Strong” patents;
  3. Reducing uncertainty under Section 101.

He committed to using AI tools where it makes sense to improving examination (both quality and efficiency).

In his written responses to the Senate Judiciary Committee, Squires laid out a broad vision of restoring the USPTO “to its rightful place atop the world as executor of our Nation’s constitutional mandate and to boost America’s ingenuity engine with the intellectual property that drives economic growth, technological progress, and global competitiveness.”   He expressed opposition to abusive “patent troll” tactics, describing them as “predatory arbitrage plays.” He committed to transparency in foreign litigation funding while reiterating his belief in strong IP protections as an important aspect of US foreign trade policy.

As Squires takes the helm, Acting Director Coke Morgan Stewart will move to her permanent role as Deputy Director. Stewart deserves congratulations for navigating the USPTO through a turbulent period – implementing President Trump’s policy shifts while keeping the agency running at full steam.

The USPTO Director serves as both Under Secretary of Commerce for Intellectual Property and Director of the USPTO, requiring Senate confirmation. This dual role means the Director must balance:

• Operational management of ~13,000 USPTO employees
• Policy development for U.S. intellectual property law
• International IP cooperation and treaty negotiations  
• Stakeholder engagement across diverse patent community
• Congressional oversight and budget management

35 U.S.C. § 3(a).

Supreme Court Asked to Resolve ‘Secret Springing Prior Art’ Controversy in IPR Proceedings

Patent

by Dennis Crouch

Inter partes review have been shown to be a powerful mechanism for challenging and ultimately cancelling questionable patents.  The process was designed by Congress to be somewhat streamlined and thus has a strict limitation that IPR trials only focus on novelty/obviousness and, those challenges must be based only on "prior art consisting of patents or printed publications."  35 U.S.C. § 311(b).

In ordinary patent law, a prior art printed publication consists of some document that was published before the "critical date" of the patent application.  Although Section 102 was reorganized somewhat by the America Invents Act, this principle still rings true today as it has for the past 150+ years.

But, here is where it gets weird: in Lynk Labs, the Federal Circuit concluded that for the purposes of 311(b), a "prior art ... printed publication" includes documents that were published well after the challenged-patent's filings date. Treating these as two separate requirements, the court found that a reference could be used so long as it (1) qualified as prior art; and (2) was  ultimately published at some point.

Now, Lynk Labs has petitioned the Supreme Court for a writ of certiorari asking:

Whether patent applications that became publicly accessible only after the challenged patent’s critical date are “prior art * * * printed publications” within the meaning of 35 U.S.C. § 311(b).

Lynk Labs, Inc. v. Samsung Electronics Co., Ltd., No. 25-308 (petition filed Sept. 2025).

Promoting the Progress: Patents, Knowledge, and the Pursuit of Happiness

Patent

by Dennis Crouch

It is Constitution Day 2025, and I am freshly inspired by a lecture from my Colleague Dr. Carli Conklin on the "pursuit of happiness" as used in the Declaration of Independence. Her scholarship reveals the phrase is not a hedonistic right that might be implied when used today, but rather part a collective project of human flourishing rooted in virtue, knowledge, and useful improvements.  Although the Declaration is not directly part of the Constitution document, Professor Akhil Reed Amar's new book, BORN EQUAL: Remaking America's Constitution, 1840-1920, argues that the Declaration's ideals and commitments continued to reshape American constitutional development long after the founding era.  In this book, he particularly focuses on how it worked through President Abraham Lincoln during and immediately after the Civil War.

Although "pursuit of happiness" is typically seen as a liberty interest -- a freedom from governmental interference -- historical record also reveals many examples of a more action-oriented approach, where that promise for the people calls for government action to eliminate barriers and "promote the progress."  In his first annual message to Congress in 1790, President George Washington declared that "knowledge" is "the surest basis of public happiness."  That same speech also urged Congress to act quickly to give "effectual encouragement" to this pursuit, particularly for the "introduction of new and useful inventions" into the United States. Within a few months of President Washington's speech, Congress responded with the Patent Act of 1790.

This post is intended to highlight this underappreciated connection that might already be apparent: the patent system represents one of the federal government's earliest (and most successful) efforts to transform a somewhat abstract right to pursue happiness into a concrete program that enables individual citizens to flourish through innovation and discovery. At the same time, it was never only about private gain. Promoting the progress of the useful arts means channeling individual ingenuity toward improvement of the common good -- ensuring that the fruits of invention would ultimately expand the shared store of knowledge that improves the nation as a whole.  In that same 1790 speech, I see Washington referring to this when he spoke of fostering "a wise and happy Government."

The PowerBlock Problem: A Roadmap for Dodging Patent Eligibility Hurdles

Patent

by Dennis Crouch

Accused infringer iFit Inc. has filed a combined petition for panel rehearing and rehearing en banc in PowerBlock Holdings, Inc. v. iFit, Inc., No. 24-1177 (Fed. Cir. filed Sept. 10, 2025), challenging the Federal Circuit's recent decision finding the  automated exercise equipment claims eligible. The petition argues that the panel's holding directly conflicts with the court's precedent in Yu v. Apple Inc., 1 F.4th 1040 (Fed. Cir. 2021) as well as Supreme Court precedent by allowing systems to avoid ineligibility simply by reciting conventional components that perform basic functions at a high degree of generality.  The patent in this case seems to me similar to so many others -- it claims a known physical system at a fairly high level of generality and couples that with previously unknown information processing.  This combination was enough to overcome an abstract idea challenge - and suggests a roadmap for artful dodging of the eligibility hurdles.  In my view, the PowerBlock panel also seems to have have applied a mechanical versus software distinction that is not supported by Supreme Court precedent.

I hope that the original panel will take a hard look at their reasoning. As noted below, I believe there are a couple of specific errors that could be fixed while still reaching the same outcome. That result would help insure that this decision avoids working potential mischief.

Still Pending: Three Mandamus Petitions Test USPTO’s Expanded Denial Powers

Patent

The Federal Circuit is still sitting on a trio of related mandamus petitions asking the  Court to step-in against the USPTO's 2025 up-ramp of discretionary denial practice.

  • In re SAP America, Inc., No. 25‑132 and 25-133 (petition filed Jun 16, 2025; briefing complete);
  • In re Motorola Solutions, Inc., No. 25‑134 (petition filed June 23, 2025; briefing complete); and
  • In re Google LLC, No. 25‑144 (petition filed August 18, 2025; briefing is ongoing).

In the early days, the USPTO granted very few discretionary denials. Those expanded  somewhat under Director Iancu (Trump-I); then retracted somewhat under Director Vidal (Biden).  Acting Director Stewart (Trump-II) has blown past Dir. Iancu in her approach, greatly expanding the use of discretionary denials.

Genetic Patents Catch-22: Can Challenging a Patent Requires Risking Infringement?

Patent

by Dennis Crouch

An interesting mandamus petition is pending from Inari Agriculture -- asking the Federal Circuit to overturn the PTAB institution denial in a PGR challenging Pioneer Hi-Bred's inbred corn patent. U.S. Patent No. 11,659,803.  In its decision, the PTAB denied Inari's obviousness challenge because it failed to sequence and analyze the genome of the deposited seed that defines the claimed plant variety. Inari argues this creates an unconstitutional "Catch-22" where challengers must risk patent infringement liability to file adequate PGR petitions, violating due process and separation of powers principles. [In re_-_ Inari Agriculture, Inc. Petition].

The '803 patent claims "seed, plant, plant part, or plant cell of inbred maize variety 1PFLQ21, representative seed of the variety having been deposited under NCMA accession number 202212046." The specification describes the variety solely through phenotypic characteristics (plant height, silk color, ear length) listed in Table 1, without providing genetic sequence data. Inari's PGR petition argued the claims were obvious based on prior art disclosing the variety's parent line PH1V5T and related varieties with similar phenotypic properties, following the approach endorsed by the Board in Ex parte C, 27 U.S.P.Q.2d 1492 (BPAI 1992), where plant utility claims were found obvious based purely on phenotypic comparison without deposit analysis.

As I noted in my 2024 post, this case is part of a larger ongoing patent dispute between these two companies and there is also a good amount of interesting strategy where Pioneer has obtained patents while keeping the parent lines secret. See, Dennis Crouch, Trade Secrets vs. Patents: Pioneer's Plant Patent Strategy Raises Thorny Issues, Patently-O (Oct. 24, 2024).

Forgetting the Evidence: How Sherman Lost on Obviousness Before and After LKQ

Patent

by Dennis Crouch

Dynamite Marketing, Inc. v. The WowLine, Inc., 2024-1523, 2024-1525 (Fed. Cir. Sept. 12, 2025) (non-precedential)

This case involves design patent infringement claims over the "Wallet Ninja," a credit-card-sized multi-tool covered by U.S. Patent No. D751,877.   Patentee Dynamite Marketing sued Sherman Specialty (d/b/a The WowLine, Inc.).  The case was complicated by inventorship disputes involving LaErik Cooper, a mechanical engineer who assisted in developing the design but was not named as an inventor on the patent. A jury ultimately found that Cooper was not entitled to co-inventor status, that Sherman willfully infringed the valid patent through its competing "TOL4" product line, and awarded Dynamite $1,850,000 in lost profits damages. The district court then awarded $1.54 million in attorney fees, bringing the total judgment to over $3.5 million.

On appeal, the Federal Circuit dismissed Sherman's challenge to the inventorship determination because Sherman lacked standing to appeal that issue, since it was not a party to Cooper's inventorship counterclaim and Cooper himself did not appeal his loss. The court affirmed all other aspects of the district court's decision -- including a non-obviousness finding that survived even after the Federal Circuit's intervening LKQ decision changed the legal standard for design patent obviousness.

Application of Fifth Circuit’s Heightened § 1404(a) Standard in Patent Cases

Patent

by Dennis Crouch

In re VirtaMove, Corp., No. 2025-130 (Fed. Cir. Sept. 11, 2025) (Google case); In re VirtaMove, Corp., No. 2025-138 (Fed. Cir. Sept. 11, 2025) (Amazon case).

Federal Circuit has denied this pair of related mandamus actions.  In both cases, the patentee VirtaMove challenged venue transfer orders moving its patent infringement suits from the Western District of Texas to the Northern District of California. As I discuss below, the non-precedential decisions have some interesting jurisdictional tension with recent Fifth Circuit law.

VirtaMove is a small Canadian software company holding patents on secure application containerization technology. VirtaMove sued Google LLC and Amazon Web Services in the Midland/Odessa Division of WDTX, alleging infringement of patents covering methods for migrating applications into portable, secure containers. Both defendants successfully moved to transfer under § 1404(a), with the district courts (Judge Counts in the Google case, Judge Albright in the Amazon case) finding that the Northern District of California was more convenient primarily due to the concentration of defendants' engineers involved in developing the accused products in the San Francisco Bay Area. VirtaMove's central argument on mandamus was that the district courts misapplied governing law by following Federal Circuit precedent rather than more recent Fifth Circuit authority that VirtaMove claimed established heightened standards for transfer.

28 U.S.C. § 1404(a) provides that "[f]or the convenience of parties and witnesses, in the interest of justice, a district court may transfer any civil action to any other district or division where it might have been brought." I think of this as the "convenient forum rule" which is separate and distinct from the "proper" venue requirements of §§ 1391 and 1400(b).  

§ 1404(a) allows courts to determine where the case should be tried for optimal convenience and judicial efficiency. Someone seeking to move a case from one location to another (or as here move-it-back) bears the burden of demonstrating that the proposed transferee forum is "clearly more convenient" than the current venue by analyzing private interest factors (convenience of parties and witnesses, location of evidence, costs of litigation) and public interest factors (administrative difficulties, court congestion, local interest in deciding local controversies, and familiarity with governing law). These factors are not found in the statute, but rather are derived from a variety of precedent.

Shira Perlmutter is (Temporarily) Back in Charge at Copyright Office

Patent

by Dennis Crouch

In a significant victory for Register of Copyrights Shira Perlmutter, the D.C. Circuit Court of Appeals has granted her emergency motion for an injunction pending appeal, allowing her to continue serving in her role while challenging President Trump's attempt to remove her from office. Perlmutter v. Blanche, No. 25-5285 (D.C. Cir. Sept. 10, 2025). The per curium order is a terse one paragraph, but two judges filed a detailed concurring opinion explaining why a preliminary injunction is useful in this case -- writing that removal of Perlmutter “would be a grave intrusion by the President into the constitutional powers of a coordinate branch of government.” Although this is an intellectual property case, it is also fundamentally about separation of powers issues within the U.S. government -- and particularly about executive control over aspects of the government in situations where Congress has attempted to reduce or eliminate Presidential power.

Although Copyright Office control may be less important to the President than other areas, I still expect an emergency application to the Supreme Court from the DOJ to overturn this ruling. The court's order enjoins "Todd Blanche, Paul Perkins, Sergio Gor, Trent Morse, and the Executive Office of the President, and their subordinates and agents" from "interfering with appellant's service as Register of Copyrights and Director of the U.S. Copyright Office pending further order of the court." The district court had denied Perlmutter's request for a preliminary injunction.

President Trump has been successful in other situations at removing statutory-protected officers - with the Supreme Court rejecting similarly preliminary injunctions in Trump v. Wilcox, 145 S. Ct. 1415 (2025), and Trump v. Boyle, 145 S. Ct. 2653 (2025). Wilcox involved the President's removal of members of the National Labor Relations Board and Merit Systems Protection Board without cause, with the Supreme Court staying lower court injunctions that would have prevented the removals. Boyle applied identical reasoning to the Consumer Product Safety Commission.  The statutes provide the President with authority to remove these individuals for cause - based upon "neglect of duty or malfeasance" - but President Trump argues that he has inherent power to remove any member of the administration exercising executive power.   The Supreme Court did not decide the merits directly but found significant potential harm from allowing a removed officer to continue exercising executive power.

The Copyright Office situation is different because the Register serves in the Legislative Branch as part of the Library of Congress, with a primary responsibility of advising Congress on copyright matters rather than executing presidential policies.  The President has no statutory removal authority over the Register. And, as far as I know, this is the first time a President has ever attempted to remover the Register in the long history of the U.S. Copyright Office.

But, the Register also has clearly administrative functions, including registering copyrights and maintaining copyright deposits, recording transfers of copyright ownership, and exercising rulemaking authority.  The disagreement in the concurring and dissenting opinions focus on whether these roles constitute the exercise of substantial executive power, with the majority taking pains to distinguish Wilcox and Boyle.

While I believe the copyright issue is important, the upcoming big fight for the big banana is likely over the Federal Reserve and its ongoing independence from the other branches of government.

Supreme Court Grants Cert in Parallel Cases from Federal Circuit and DC Circuit

Patent

by Dennis Crouch

Although it is a non-patent tariff case, I have been writing about Trump v. V.O.S. because of its pathway through the Federal Circuit – a court that I write about on a daily basis. The court seems to have skillfully avoided the brunt of President Trump’s ire even while ultimately holding that the President’s tariffs represent an unconstitutional action that go beyond the powers delegated by Congress.  The Department of Justice quickly filed a petition for certiorari, and the Supreme Court has now granted cert alongside a second case appealed from the D.C. Circuit Court of Appeals.  The cases are consolidated with expedited briefing over the next two months with oral arguments to be held in November 2025.

In Learning Resources, Inc. v. Trump, No. 24-1287, and Trump v. V.O.S. Selections, Inc., No. 25-250, the Court will address fundamental questions about the scope of presidential power to regulate international trade during declared national emergencies. The cases challenge Trump’s “Trafficking Tariffs” (imposing duties on all goods from Canada, China, and Mexico as leverage against on fentanyl import concerns) and “Reciprocal Tariffs” (applying across-the-board duties of 10-50% on imports from virtually all other countries to address imbalances in the trade in goods).  The Federal Circuit struck down the tariffs in a 7-4 en banc decision in August 2025, finding that IEEPA’s grant of power to “regulate” imports may include some tariff setting, but it does not encompass the virtually unlimited tariff authority sought by the President. The Learning Resources case is not based upon a substantive ruling from the D.C. Circuit, but only a stay of lower court injunctions. (more…)

Converting Voluntary Dismissals: Federal Circuit Holds Sanctions Can Create Prevailing Party Status Under § 285

Patent

by Dennis Crouch

The Federal Circuit's decision in Future Link Systems, LLC v. Realtek Semiconductor Corporation, No. 2023-1056 (Fed. Cir. Sept. 9, 2025), provides important clarification on when a defendant becomes a "prevailing party" and thus eligible for attorney fees under 35 U.S.C. § 285 and costs under Federal Rule of Civil Procedure 54(d)(1).  Although the case had been voluntarily dismissed by the patentee without prejudice, Judge Albright had subsequently converted the status to with prejudice as a sanction for filing objectively baseless patent infringement suits. That conversion was sufficient judicial imprimatur to leave the defendant as prevailing party.

The Tea: The district court's sanctions decision appears to have been influenced by the discovery that the patentee Future Link had entered into a licensing agreement with MediaTek (a Realtek competitor) in 2019 that provided a litigation bounty: an extra $1 million if Future Link sued Realtek or forced it to pay a license fee by a set date.  See the U.S. Department of Justice’s Statement of Interest and Realtek’s publicly filed complaint here (PDF), which quotes the bounty terms, and a court-hosted copy of the allegations here.  The DOJ filing (under President Biden) highlighted allegations that the bounty fueled a series of PAE suits aimed at raising a rival’s costs rather than resolving genuine patent disputes.

Federal Circuit Delivers Major Reversal on “Software Per Se” Rejections in In re McFadden

Patent

by Dennis Crouch

In a significant victory for software patent applicants, the Federal Circuit reversed the a PTAB rejection of computer system claims in In re McFadden, 2024-2107 (Fed. Cir. Sept. 5, 2025).  One problem with the decision is its non-precedential status – even though it clearly breaks new ground.  The case offers another example of the potential power of 112(f) means-plus-function claims.

Brian McFadden’s U.S. Patent Application No. 16/231,749, claims systems and methods for location aware social media posting.  The examiner had rejected claims 10-18 under § 101 as “software per se” without structural recitations, and claims 10-17 under § 112(b) as indefinite mixed claims reciting both apparatus limitations and method steps. The Board affirmed both of those rejections, but the Federal Circuit has now reversed on § 112(b) and vacated and remanded on § 101, ordering the Board to proceed with Alice/Mayo analysis rather than stopping at the statutory category inquiry.

McFadden’s claims do not recite any real structural limitations, but rather use broad non-technical words such as “a module” and “a subsystem.”  The Board found these insufficiently concrete and thus identified the claims as directed to “software per se” without “a physical or tangible form” and thus did not fall within any Section 101 statutory category (process, machine, manufacture, composition of matter).  On appeal, the Federal Circuit found these “nonce words” should be interpreted as means-plus-function and that recitation of corresponding generic computer hardware descriptions in the specification can provide sufficient structure to avoid “software per se” rejection.

The decision also has some interesting thoughts on indefiniteness for system claims that incorporate functional language, distinguishing between impermissible mixed system/method claims and permissible system capability claims.

Notably, McFadden pursued his patent and appeal pro se and won. Congratulations! (more…)

Discovery Gamesmanship Backfires: Federal Circuit Orders New Trial After Defendant’s Bait-and-Switch on Testing Requirements

Sept. 8, 2025), the Federal Circuit reversed a district court's denial of a new trial motion, finding that defendants' "improper and prejudicial" trial arguments were not harmless error where the jury returned a general verdict of noninfringement. The case arose from Phillips 66's alleged infringement of patents related to desulfurizing heavy marine fuel oil to comply with International Maritime Organization sulfur content requirements.  See U.S. Patent No. 10,308,884.  One frame to see the case is as a backfire demonstration: Here, defendants fiercely resisted producing evidence during discovery, then later at trial pointed to the absence of that very evidence to defeat plaintiff's case. Although the district court permitted this approach, the appellate panel did not.

Writing for a three-judge panel, D.N.J. Chief District Judge Renée Marie Bumb (sitting by designation) found error in permitting Phillips to present this non-infringement argument.  Although there were alternative non-infringement theories, the general verdict meant that there was no way to discern whether the verdict was impacted by the "prejudicial noninfringement theory."

Cox v. Sony and the Future of Patent Contributory Liability: How a Copyright Case Could Reshape Patent Law

Patent

by Dennis Crouch

The Supreme Court's pending decision in Cox Communications v. Sony Music is a copyright case focused on internet service provider liability, but it also has the potential of reshaping patent law doctrine. Briefing is ongoing in the merits case which will be likely decided in Spring 2026. Cox Communications, Inc. v. Sony Music Entertainment, No. 24-181 (U.S. cert. granted July 1, 2025). The case centers on whether an ISP can be held liable for contributory copyright infringement for continuing to provide internet access to subscribers it knows are repeat infringers, without proof of specific affirmative conduct to promote infringement. Adjudged infringer Cox argues that the Fourth Circuit's approach in the case uses a diluted standard for "material contribution" that threatens to unravel decades of carefully calibrated secondary liability doctrine. The music industry counters that Cox's conduct went beyond passive provision of service - by knowingly maintaining internet access for accounts that received tens of thousands of infringement notices, Cox substantially assisted ongoing piracy and should face liability.

While directly focused on copyright, the case is likely to have direct impact on patent law doctrine as well.  This spillover stems from the recognized "historic kinship" between patent and copyright contributory liability standards.  The two questions presented as:

  1. Whether knowledge plus continued provision suffices for contributory liability; and
  2. Whether willfulness requires awareness that one's own conduct is unlawful (i.e., infringement).

Answers to both questions will almost certainly influence how courts interpret parallel doctrines under under both § 271(b) (inducement) and § 271(c) (contributory infringement) as well as enhanced damages for willful infringement.

Mea Culpa: Trump Administration Moves Swiftly on Tariffs Appeal

Patent

by Dennis Crouch

In my prior posts about the Federal Circuit's V.O.S. Selections decision, I suggested the Trump administration may "slow-walk the petition for certiorari while continuing to disrespect the judgement made by both the trial and appellate courts." I was wrong. Rather, the administration has already petitioned for certiorari and requested expedited consideration, filing just days after the Federal Circuit's August 29 decision. The petition frames this as an existential economic crisis, with Treasury Secretary Bessent declaring that tariffs are critical to save an America at "the brink of a major economic and national-security catastrophe."

Although obviously always unpredictable, I expect the Supreme Court will grant certiorari and will reverse the Federal Circuit's judgment that the Tariffs went beyond the statutory delegation of authority.
