Plagiarism Police come for Winston & Strawn

Hsuanyeh Law Group v. Winston & Strawn, 23-cv-11193 (S.D.N.Y. 2024)

A recent copyright infringement lawsuit filed by small Boston intellectual property boutique Hsuanyeh Law Group PC (HLG) against international giant Winston & Strawn LLP focuses a dividing line that can highlight when copying the work of another firm is permissible.  I believe that Winston & Strawn will eventually prevail based upon a fair use defense, but it is still an embarrassing situation for the firm and attorneys involved.  I hope that they did not overbill the client.  The role of attribution is also receiving increasing focus as attorneys begin to rely more heavily on AI outputs for their legal documents.

Federal Circuit Affirms Invalidity of Genus Claims to Stevia Production Method Lacking Written Description and Narrower Claims as Combining Natural Phenomena with an Abstract Idea

by Dennis Crouch

In PureCircle USA Inc. v. SweeGen, Inc., No. 22-1946 (Fed. Cir. Jan. 2, 2024) (non-precedential) [PureCircle Decision], the Federal Circuit affirmed a district court summary judgment siding against the patentee, PureCircle.  The court concluded that the stevia production method claims were all invalid, either for: (1) lack of written description for the genus claim or (2) lack of eligibility because the claims are directed to a natural phenomenon combined with an abstract idea.  Judge Dyk authored the opinion of the court that was joined by Judges Schall and Stark affirming the ruling of C.D.Cal Judge James Selna.

The written description portion of the opinion parallels the Supreme Court's 2023 Amgen decision that focused on the sibling doctrine of enablement. Although non-precedential, the eligibility portion appears important because of the way it combines prohibited eligibility categories and rules that method claims requiring a particular purity level are themselves an abstract idea absent requirement of specific steps on how that purity level is achieved.

The First Precedential Patent Decision of 2024: Dexcom v. Abbott Diabetes Care

by Dennis Crouch

The U.S. Court of Appeals for the Federal Circuit has begun 2024 [2023] with its first precedential patent decision in DexCom, Inc. v. Abbott Diabetes Care, Inc., 2023-1795 (Fed. Cir. January 3, 2024).  In an opinion by Judge Stoll, the court affirmed a district court decision denying DexCom’s motion for a preliminary injunction. The patentee had requested an order barring Abbott from pursuing its IPR challenges - based upon a forum selection clause that was part of a prior settlement between the parties. Judges Dyk and Hughes were also on the panel.

Patent Law Exam 2023: Are you Smarter than a Law Student?

by Dennis Crouch

The following is my patent law exam from this past semester. As in years past, the exam was worth less than half of the final grade because the students did other substantial work during the semester, including a major moot court competition.   Students were permitted access to their book/notes/internet, but were barred communications with another human during the exam.

This year's exam is very loosely based upon an interesting patent that I found associated with the Tow Whee product created by Eric Landis.  See US11167164, US11731470, and US11724148.  But, the events described are entirely my creation.

Federal Circuit Appellate court Grants Emergency Stay of Apple Watch Ban

by Dennis Crouch

The patent battle between Masimo and Apple over pulse oximetry technology in the Apple Watch took a new turn on December 27th. Despite the recent import ban imposed by the U.S. International Trade Commission (ITC), Apple was granted a temporary stay by the U.S. Court of Appeals for the Federal Circuit. For now, this emergency ruling blocks the government from enforcing the exclusion order on certain Apple Watch models through at least mid-January. However, the legal fight is far from over. For Masimo, this short-term win for Apple weakens its bargaining position as the two companies continue their protracted patent dispute in courts and before regulatory agencies.

Emergency Appeal of the Apple Watch Ban

by Dennis Crouch

December 25th, marked the deadline for President Biden to reject the U.S. International Trade Commission's (USITC) ruling banning imports of certain Apple Watch models. With no action from the White House, Apple now faces a federal government order to halt imports and sales of Apple Watch Series 9 and Ultra 2 devices because it incorporates light-based pulse oximetry technology covered by the claims of Masimo's U.S. Patent Nos. 10,945,648 (claims 24 and 30) and 10,912,502 (claim 22).

No Patent for Robot Inventions: UK Supreme Court Rules on AI Inventorship in Thaler v. Comptroller-General

by Dennis Crouch

Thaler v. Comptroller-General of Patents, Designs and Trade Marks, [2023] UKSC 49. 

In a December 20, 2023 decision, the UK Supreme Court has agreed with American courts that an inventive machine is not deserving of patent rights.  The underlying case will be familiar to many with Dr. Stephen Thaler of St. Louis seeking to patent a thermal-mug designed by an artificial intelligence machine that he created.  Thaler has argued that the AI (called DABUS) conceived of the particular invention in question and also identified its practical utility.  The UK Supreme court based its holding upon the text of the UK Patents Act of 1977 as it reached the same ultimate conclusion as the Federal Circuit in Thaler v. Vidal, 43 F.4th 1207 (Fed. Cir. 2022), cert. denied, 143 S. Ct. 1783 (2023).

These Thaler cases showcase that under the current patent law regime, autonomous AI systems cannot qualify as inventors entitled to patent rights, irrespective of their creativity. For AI-generated inventions to become patentable, intervention by policymakers to amend inventorship laws would likely be necessary. However, the arguably bigger questions of immediate importance surround collaborative human-AI inventions where both human and machine contribute in creation of a new invention. Thaler expressly disclaimed any human input into DABUS’s inventions, but going forward mixed human-AI inventor teams seem inevitable. Neither the UK Supreme Court’s decision nor the parallel US rulings provide direct guidance on the requisite threshold quality or quantity of human participation in such collaborative inventions to satisfy legal inventorship requirements. Thus, for instance, an open issue remains whether token perfunctory human approval of an AI-devised invention would suffice, or if substantive intellectual contribution is needed. And for primarily AI-driven inventions, are minor tweaks by a human collaborator enough? Or must the human contributor objectively supply the novel concept?

The Battle Over Domicile Disclosure by Trademark Applicants

by Dennis Crouch

In the pending appeal of In re Chestek, PLLC, No. 22-1843, a trademark applicant is opposing the USPTO requirement that all applicants must disclose their domicile address. This requirement, referred to as the “domicile address rule,” has been controversial since the USPTO adopted it in a 2019 rulemaking. For individuals, this rule requires an actual residential address.  See Requirement of U.S. Licensed Attorney for Foreign Trademark Applicants and Registrants, Final Rule, 84 Fed. Reg. 31498 (July 2, 2019).  The outcome could have significant implications for privacy and transparency in the trademark registration system.  For a variety of reasons, many people do not publicly disclose their place of residence. In the US, the most common reasons stem from domestic violence and stalking. Although the USPTO is attempting to offer a mechanism to protect domestic residence from public view, it also recently had a major data loss of that information -- and effectively all domestic residence information is available in various sources online.  A decision favoring the petitioner would also be seen as bolstering the Administrative Procedure Act’s notice and comment requirements.

The best place to begin any analysis is probably with the statute.
