When (and Where) Does Amazon’s APEX Create Personal Jurisdiction

By Dennis Crouch

The Supreme Court will soon consider whether to review what I see as an important Federal Circuit decision finding personal jurisdiction based solely on a patentee's use of Amazon's private patent enforcement system. In Lighting Def. Grp. LLC v. SnapRays LLC, No. 24-524 (petition filed Nov. 5, 2024), Arizona-based LDG submitted a patent infringement complaint against Utah-based SnapPower through Amazon's Washington-based Patent Evaluation Express (APEX) program.  To be clear: this is a private arbitration system that relates to selling on Amazon - it is not a federal court case.  Under APEX, Amazon notifies accused sellers who have three weeks to either participate in Amazon's evaluation process, settle with the patent owner, or file a declaratory judgment action - otherwise their listings are removed.

SnapPower sued in Utah federal court seeking a declaratory judgment of non-infringement and invalidity. However, the district court dismissed for lack of personal jurisdiction since LDG (an AZ company) had no contacts with Utah. On appeal, the Federal Circuit reversed, holding that LDG's use of the APEX system knowing it would affect SnapPower's Utah operations was sufficient to create jurisdiction there. The cert petition argues this conflicts with Supreme Court precedent requiring contacts with "the forum State itself, not the defendant's contacts with persons who reside there." Walden v. Fiore, 571 U.S. 277 (2014).

Price Quote’s Written Acceptance Requirement Fails to Shield Patents from On-Sale Bar

by Dennis Crouch

The Federal Circuit has ruled that Crown Packaging's high-speed necking machine patents are invalid under the pre-AIA on-sale bar, reversing a Virginia district court's summary judgment decision. Crown Packaging Technology, Inc. v. Belvac Production Machinery, Inc., Nos. 2022-2299, 2022-2300 (Fed. Cir. Dec. 10, 2024).  The court held that a detailed price quotation marked "subject to written acceptance" can still constitute an invalidating offer for sale and not merely an invitation to make an offer.

Ooh la la ... high speed necking.  For those wondering, "necking" in the beverage can industry refers to the manufacturing step of reducing a can's diameter at the top to create the tapered shape we drink from. Crown's patents at issue in the case (U.S. Patent Nos. 9,308,570; 9,968,982; and 10,751,784) protect their horizontal, multi-stage necking machines designed for such high-speed production.

Institutional Stonewalling: The Federal Circuit’s Silent Treatment Through Rule 36

by Dennis Crouch

Relationship expert John Gottman famously identified "stonewalling" as one of his "Four Horsemen of the Apocalypse" that predict relationship failure. Stonewalling occurs when one partner withdraws from interaction, refusing to engage or respond meaningfully to the other's concerns. The behavior is particularly toxic because it leaves the other party feeling ignored and invalidated, while also preventing any real progress toward resolution. In many ways, the Federal Circuit's prevalent use of Rule 36 summary affirmances operates as a form of institutional stonewalling - responding to carefully crafted legal arguments with a single word "AFFIRMED" while refusing to explain its reasoning. That practice is now under intense scrutiny, with Island IP pressing a two-front challenge through Supreme Court filings this week.  In addition to filing its reply brief in Island Intellectual Property LLC v. TD Ameritrade, Inc., No. 24-461, Island IP has also submitted an amicus brief supporting the parallel petition in ParkerVision, Inc. v. TCL Industries Holdings Co., No. 24-518.

Making Changes: (Negative) Impact of Rewriting the Provisional Specification

by Dennis Crouch

Patent attorneys know that amending the specification can directly impact claim interpretation. The Federal Circuit in Phillips v. AWH Corp. placed the specification alongside claim language as foundational intrinsic evidence for claim construction, recognizing that the specification provides focused context for understanding claim terms as they would be understood by skilled artisans. 415 F.3d 1303 (Fed. Cir. 2005).  Amendments made during prosecution carry particular weight because they represent deliberate choices by the applicant to alter a known baseline. Although practitioners don't always think of it this way, one of the most significant opportunities for "amending" patent disclosure comes when moving from a parent to a child application. This transition - particularly when moving from a provisional to a non-provisional application - often serves as a natural inflection point where attorneys engage in cleanup, clarification, and refinement. But as recent Federal Circuit decisions make clear, these often routine editorial choices between applications can have profound implications for claim scope, even without rising to the level of formal prosecution disclaimer.

The case prompting this post is the DDR Holdings, LLC v. Priceline.com LLC, No. 2023-1176 (Fed. Cir. Dec. 9, 2024), claiming methods and systems for generating a composite web page that combines content along with ads from third-party “merchants.”  U.S. Patent No. 7,818,399.  I think the idea here is similar to create a  white-label or embedded shopping experience. When a user clicked on a product link, instead of being redirected to the merchant's site, they would see a new composite web page that maintained the host website's look and feel while displaying the merchant's product information.  Although the ability to embed shopping experiences is integral to web technology today, it wasn't so clear back when DDR filed its original provisional application back in 1998.

The dispute centered on whether the claim term "merchants" was limited to sellers of goods or could also include service providers.  Travel companies like Booking.com and Priceline.com are quintessential service providers - they don't sell physical goods but rather facilitate services like hotel bookings, airline tickets, and car rentals.

Dual Sanctions: Courts Can Layer Inherent Power Sanctions on Top of § 285 Awards

by Dennis Crouch

In PS Products, the Federal Circuit has affirmed that district courts may impose deterrence sanctions under their inherent powers even after (or in addition to) awarding attorney fees under 35 U.S.C. § 285. PS Prods. Inc. v. Panther Trading Co., No. 2023-1665 (Fed. Cir. Dec. 6, 2024).

A Hole in the Whole: Federal Circuit Makes Inherency an Easier Path to Obviousness

The Federal Circuit recently issued an important decision further developing the role of inherency in patent law's obviousness analysis. In Cytiva Bioprocess R&D AB v. JSR Corp., the court addressed how inherent properties interact with reasonable expectation of success and claim construction, providing important guidance that builds upon its 2020 Hospira decision.

Looking ahead, Cytiva appears to strengthen the hand of patent challengers by making it easier for the PTAB to invalidate patents that claim inherent properties of otherwise obvious inventions. The Federal Circuit's framework essentially creates a streamlined path to unpatentability when properties inherent to the prior art are claimed without being essential to the objective motivation for creating the invention. While the decision attempts to carve out protection for claims where knowledge of inherent properties is necessary for motivation to combine or modify prior art, the practical effect may be to narrow the scope of patent protection available for discoveries of new properties in known compositions or processes.

The title of this blog post - A Hole in the Whole - refers to the Federal Circuit's new framework of dividing obviousness analysis into two parts: first assessing the obviousness of a base combination of some of the limitations, then separately dismissing functional limitations as inherent properties, undermining Section 103's requirement to evaluate claims 'as a whole.'"

Expert Witness Ethics and Economics: Unpacking the Federal Circuit’s En Banc Review of Damages Testimony in EcoFactor v. Google

by Dennis Crouch

This is a post about damages expert testimony and the pending en banc case of EcoFactor v. Google. But, before delving into those details I wanted to first provide a personal anecdote -- my experience with expert witnessing.

My personal experience with expert witnessing has been quite limited but instructive.  While expert witnesses are charged with providing truthful and complete testimony, they are inevitably selected and compensated based upon their predicted ability to support a particular party's position. Although my compensation wasn't directly contingent on favorable testimony, I recognized that future engagements would depend on my perceived effectiveness as an advocate.  I started getting an icky feeling - a strong tug on my conscience. I particularly recall the internal pull to shade the truth in the client's favor and even began to think of the client as "my client."  That is an ethical problem.  The expert witness is expected to serve as an independent advisor to the court, providing objective analysis based solely on the facts and their expertise. This fundamental tension between duty to the court and financial incentives ultimately led me to step away from expert witnessing entirely.  If I'm going to be a "hired gun," I want to do so as the attorney where my ethical duty is to side with my client rather than as a quasi-objective expert witness.

While most expert witnesses are not attorneys, the modern American expert witness system essentially places compensated advocates on the stand.  The folks who are hired to testify are great at testifying.  I like the quote I found in a Unified Patents brief from a century ago where P.G. Wodehouse captured this reality in Mike and Psmith: "He was rigidly truthful, where the issue concerned only himself. Where it was a case of saving a friend, he was prepared to act in a manner reminiscent of an American expert witness." In the quote, Wodehouse suggests that an expert witness's testimony, while technically under oath, may be shaped more by allegiance to the retaining party than by rigid adherence to objectivity.

USPTO Withdraws Controversial Terminal Disclaimer Rule – But Core Issues Remain

by Dennis Crouch

As I previously suggested, the USPTO has now announced that it is withdrawing its proposed rule that would have made terminal disclaimers far more noxious by tying patent enforceability to the validity of claims in related patents. While this is undoubtedly the right move given the questionable legal authority and overwhelmingly negative public response (over 300 comments, with 256 unique submissions), the underlying concerns that drove the proposal deserve attention because they will likely arise in other forms. [Read the Fed. Reg. Notice Cancelling the Proposal: 2024-28263]

The USPTO's core justification focused on competition and market entry barriers. When a patent owner obtains multiple patents on obvious variants, the collective cost of challenging each patent individually in litigation or administrative proceedings can arguably deter market entry. The USPTO particularly emphasized this concern in light of Biden's Executive Order 14036 on "Promoting Competition in the American Economy."  As discussed below, this same concern arises when a single patent has a large number of claims.

Many Paths to Patent Issuance

by Dennis Crouch

Daedalus's labyrinth was so complex that even its creator needed Ariadne's thread to find his way out.  I would suggest that the pathways through USPTO patent prosecution are at least as intricate and manifold. While prosecution statistics reveal some common routes through the maze—each application charts its own course through a complex network of non-final rejections, final rejections, RCEs, and after-final practice. Even experienced practitioners sometimes need their own version of Ariadne's thread.

I wanted to identify the most "typical" pathways for recently issued patents and so parsed through USPTO file wrapper data looking for rejection-response cycles as applications navigate their way to issuance. This post examines the most common prosecution pathways, accounting for 95% of issued patents.  My sample here: The two million issued patents granted from applications filed 2016-2020.  A separate post will bring-in patent families that continue to be an integral aspect of patent strategy and USPTO timelines.

The Next USPTO Director: Duffy’s Four Factor Test

by Dennis Crouch

In a prior post, I focused on President Elect Trump's nomination of Howard Lutnick as Commerce Secretary, but the most direct impact for the patent system will be the upcoming nomination of the next USPTO Director. Dennis Crouch, Howard Lutnick and the Patent System, Patently-O (November 25, 2024).  Like the Secretary of Commerce, the Director (who is also Undersecretary of Commerce) must also be nominated by the President and confirmed by the Senate under 35 U.S.C. § 3.

Professor John Duffy (UVa) recently outlined four essential qualities for the next USPTO Director. [Part 1][Part 2].  Duffy was my law professor at UChicago back in 2002, and I have deeply respected his work since then - both as a scholar and teacher.  Back then we were at the apex of broad patent eligibility doctrine.  The landscape has shifted dramatically then, with decisions like Alice and Mayo fundamentally reshaping what inventions qualify for patent protection. Duffy and I align in thinking that eligibility scope has been unduly narrowed.  We also align on another axis - that the obviousness should be robustly examined at the USPTO as the central patentability doctrine. Recall here that Duffy was one of the key forces behind KSR v. Teleflex that eliminated the Federal Circuit's more rigid "TSM" test.  As I get into this post, I also want to recognize the background that - despite these major changes to the patent system seemingly making it more difficult to obtain patent protection - the allowance rate is higher than anytime in the past 15 years. Dennis Crouch, USPTO Patent Grant Rate and Growing Backlog, Patently-O (Nov. 29, 2024).

Duffy's Four Part Framework for USPTO Leadership: First, Duffy argues that the new Director "should be open to a more reasonable, expansive, and text-based approach to patentable subject matter." As he notes, this is particularly important given the rapid advancement of information-based technologies in the 21st century. He rightly recognizes that the patent system must adapt to embrace new technological fields while maintaining its fundamental principles.

Second, the Director must possess familiarity with emerging technologies, particularly in areas like cryptocurrencies and artificial intelligence. As Duffy explains, the Director's role as Under Secretary of Commerce for Intellectual Property demands leadership across all IP fields—a scope that continues to expand with technological advancement.

Third, and perhaps most pragmatically, Duffy emphasizes the need for bureaucratic reform. Managing over 10,000 patent examiners requires not just administrative skill but also the vision to "rethink the PTO from the ground up." This is particularly relevant given the agency's evolution into what Duffy describes as a "complex Rube Goldberg machine" of initial examinations and administrative reviews.

Fourth, Duffy insists on rigorous enforcement of the nonobviousness requirement, calling it "central to the proper functioning of the patent system." This point deserves particular emphasis and expansion.

Howard Lutnick and the Patent System

by Dennis Crouch

The USPTO's position within the Department of Commerce means that Commerce Secretary nominees warrant careful attention from the patent community. President-elect Trump's nominee for Secretary of Commerce, Howard Lutnick, brings particularly relevant experience to the role, shaped by extensive involvement with the U.S. patent system both as a prolific inventor and as CEO of Cantor Fitzgerald, a company that has operated on multiple sides of patent disputes.

Supreme Court Requests Response in Edwards Safe Harbor Case

Dennis Crouch

Following my recent post examining the Edwards v. Meril safe harbor challenge, the Supreme Court has requested a response from Meril after initially receiving only a waiver. The Court's November 20, 2024 request suggests that at least one Justice sees potential merit in Edwards' challenge to the Federal Circuit's broad interpretation of Section 271(e)(1)'s safe harbor provision.  It's important to note that a request for response does not guarantee that the Court will grant the petition. In fact, the case still has a <50% odds of being granted certiorari.

The case has garnered my attention for its potential to reshape how courts interpret the "solely for uses reasonably related" language in Section 271(e)(1). The dispute arose from what might seem like a minor incident - two transcatheter heart valve systems that were brought to San Francisco from abroad for a medical conference but, as the Federal Circuit noted, ended up spending their week-long U.S. visit sitting unused in a hotel closet and storage room before heading to Europe.  Still importation is a form of infringement.

Senate Committee Advances PREVAIL Act

by Dennis Crouch

In a tight 11-10 vote, the Senate Judiciary Committee approved the PREVAIL Act (Promoting and Respecting Economically Vital American Innovation Leadership Act) that would make substantial changes to Patent Trial and Appeal Board (PTAB) proceedings. The bill addresses perceived anti-patentee imbalances in the current inter partes review (IPR) system. However, a number of Senators raised concerns and were seeking assurances about a negative impact on generic drug prices. The Bill as adopted by the Judiciary Committee included a friendly amendment by the Bill's co-sponsor Sen. Coons that attempted to address some of the drug-pricing concerns by expanding the scope of who can file IPR/PGR petitions. In particular, the original bill allowed only those sued or accused of infringement to challenge patents. As discussed below, the new approach is designed to enable petitions by generic-drug makers and non-profit patient groups. The major changes in the bill include raising the burden of proof to "clear and convincing evidence," implementing strict timing requirements for PTAB decisions, requiring greater independence of PTAB judges, establishing a "single forum" rule preventing parallel validity challenges, and strengthening estoppel provisions against repeat challenges.

Paws and Effect: Federal Circuit Rejects Indirect Causation Theory in Furbo Infringement Case

by Dennis Crouch

The Federal Circuit has affirmed summary judgment of non-infringement in DoggyPhone LLC v. Tomofun LLC, agreeing to narrowly construe the claim as requiring direct rather than indirect causation. The case involves U.S. Patent 9,723,813, which covers an "Internet Canine Communication System" that allows pet owners to remotely interact with and deliver treats to their dogs. DoggyPhone accused Tomofun's popular Furbo device of infringement, but both the district court and Federal Circuit found the accused product operates differently than what was claimed. Writing for the unanimous panel, Judge Hughes focused particularly on one key limitation requiring that the system "begins transmission to the remote client device of at least one of the audio or video of the pet in response to input from the pet."

At the heart of the dispute is a basic infringement question - whether Furbo's notification system satisfied the "begins transmission" limitation. When a dog barks, the Furbo sends a text notification to the owner's phone, but critically, no audio or video transmission begins until the owner actively clicks on that notification.  The Federal Circuit agreed with the district court that this setup does not meet the claim limitation because "transmission begins not in response to the pet's activity, but in response to the user's decision to click on the notification—making transmission responsive to the user's input, not the pet's."

USPTO Implements Substantial Fee Increases for 2025: Revenue Needs and Behavioral Incentives

by Dennis Crouch

The USPTO has issued the final rules that include significant fee increases for patent applicants (and patent challengers), all set to take effect January 19, 2025 -- the final day of the Biden Administration. While some changes appear purely driven by inflation and cost recovery, others seem designed also to modify applicant behavior in controversial ways.

Because of the timing, I believe there is some chance that parties will challenge aspects of the fee increase in court -- particularly the increased fees for late-filed continuation applications.  In my opinion, the key purpose of such an action would be to postpone implementation of the fees in order to allow a Trump appointed director to reconsider their application.

A key aspect of the America Invents Act of 2011 (AIA) provided the USPTO with fee setting authority.  Section 10 of the AIA. Every USPTO patent fee change since then has stated that the AIA fee setting authority "includes flexibility to set individual fees in a way that furthers key policy considerations."  (Citing Section 10).  If it exists, that flexibility is purely implicit.  The law itself states: "Fees may be set or adjusted . . . only to recover the aggregate estimated costs to the Office for processing, activities, services, and materials relating to patents."

Barring delayed implementation, applicants (and patent challengers) will save some dollars by ensuring that their filings beat the January 19, 2025 deadline.

The NHK-Fintiv Saga Continues: USPTO and Amicus Defend Discretionary Denials

by Dennis Crouch

The Federal Circuit is poised to address a significant administrative law question in Apple v. Vidal regarding whether the USPTO's NHK-Fintiv framework for discretionary IPR denials required notice-and-comment rulemaking under the APA. The case comes after the Federal Circuit's 2023 decision finding the procedural challenge reviewable while affirming dismissal of substantive challenges to the framework. Apple Inc. v. Vidal, 63 F.4th 1 (Fed. Cir. 2023).  The case takes on added significance given Director Vidal's recent resignation announcement. Her likely Trump appointee replacement may return to former Director Iancu's more aggressive approach to discretionary denials.

Under the AIA, the USPTO director has discretion to deny IPR petitions, even in cases where the case otherwise meets the statutory requirements for an inter partes review.  The Director has delegated authority to the PTAB to decide these issues, including discretionary denials. The NHK-Fintiv framework emerged through two precedential PTAB decisions that guide discretionary denials of IPR petitions when parallel district court litigation is pending. In NHK Spring Co. v. Intri-Plex Technologies, Inc., IPR2018-00752, Paper 8 (P.T.A.B. Sept. 12, 2018), the Board first articulated that the advanced state of parallel district court proceedings could justify denying institution. Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 11 (P.T.A.B. Mar. 20, 2020) then established six factors for evaluating such situations: (1) whether a court stay is likely; (2) proximity of the court's trial date to the Board's projected statutory deadline; (3) investment in the parallel proceeding; (4) overlap between issues raised in the petition and in the parallel proceeding; (5) whether the petitioner and the defendant in the parallel proceeding are the same party; and (6) other circumstances and merits. Director Vidal later modified (and somewhat weakened) this framework through guidance emphasizing merits-based considerations and limiting denials based solely on trial scheduling. See Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (June 21, 2022).  However, this guidance was issued without notice-and-comment rulemaking.

Safe Harbor at a Crossroads: Examining Regulatory Development Shield of 271(e)(1) in Edwards v. Meril

by Dennis Crouch

The Federal Circuit's divided ruling in Edwards Lifesciences Corp. v. Meril Life Sciences is now before the U.S. Supreme Court -- focusing on the scope of the Hatch-Waxman Act's safe harbor provision. At issue is whether 35 U.S.C. § 271(e)(1)'s regulatory development shield extends to activities conducted for both regulatory and commercial purposes. The statutory text excuses certain acts that would otherwise be considered patent infringement if conducted "solely for uses reasonably related to the development and submission of information under a Federal law which regulates the manufacture, use, or sale of drugs or veterinary biological products." While Congress intended to ensure competitors could efficiently prepare for post-patent market entry through necessary regulatory compliance work, an expansive reading arguably erodes patent rights by immunizing activities far beyond pure regulatory preparation. The safe harbor thus sits with the uncomfortable tension of promoting timely competition and protecting innovation incentives.

The case is currently proceeding through the Supreme Court's certiorari process, with Edwards having filed its petition in October 2024.  As is common in Supreme Court practice, respondent Meril waived its right to respond to the petition, and the case has been distributed for the Justices' conference on December 6, 2024, where they will consider whether to grant review.  This is a case where I expect

The Team-Based Reality of Modern Innovation: Average Patent Now Lists More Than Three Inventors

by Dennis Crouch

New data from the USPTO shows that the amazing transformation in patent inventorship continues: the average number of inventors per utility patent has reached 3.2 in 2024, nearly double the 1.7 inventors per patent seen in 1976. This steady rise in team-based inventing reflects fundamental changes in how innovation occurs and how the patent system operates.

USPTO Timeliness Slipping: Patent Term Adjustment Data Shows Growing Examination Delays

by Dennis Crouch

The USPTO has two traditional functions: (1) quality examination to ensure applications satisfy the demanding statutory requirements of patentability; and (2) timely and efficient processing of those applications. Recent data suggests the Office is struggling with the second of these mandates, as reflected in a sharp uptick in Patent Term Adjustment (PTA) awards. [Charts below]

The Rise of ‘Non-Transitory’ Claims: How a Single Word Became Key to Software Patent Eligibility

by Dennis Crouch

Recent patent prosecution data reveals a striking trend: the percentage of utility patents containing "non-transitory" software claims continued to increase -- from virtually zero 15 years ago to nearly 22% in 2024. This dramatic rise illustrates both the central role of software in our patent system and the peculiar formalistic requirements that have emerged around software patent eligibility under 35 U.S.C. § 101.

The story behind this trend begins with
