Over the past year, UK courts have issued a series of rulings requiring standard essential patent (SEP) owners to offer interim licenses in fair, reasonable, and nondiscriminatory (FRAND) cases, also holding that a SEP owner will be deemed unwilling if it refuses to do so. This has prompted jurisdictional pushback in other SEP venues: In late September, Germany’s Munich I Regional Court and the Mannheim Local Division (Mannheim LD) of the Unified Patent Court (UPC) issued the first-ever anti-interim-license injunctions (AILIs) barring the pursuit of such relief in a UK case filed by Amazon against InterDigital, Inc. Now, the UK High Court has fired back. After issuing a case management order that criticized InterDigital for taking contradictory positions on the urgency posed by the UK proceedings in order to win those AILIs, the court has issued an order enjoining the patent owner from preventing Amazon from pursuing its remaining claim for a final FRAND determination.

Parus Holdings, Inc. has filed a complaint in the Western District of Texas pleading a claim for professional negligence against Mintz Levin Cohn Ferris Glovsky and Popeo, P.C., further naming as defendants two of that law firm’s partners. It follows by a week the District of Massachusetts complaint that Mintz Levin filed against Parus, there the firm seeking (at minimum) roughly $2.2M in damages allegedly owed. These parties agree that Mintz was engaged to run a monetization program for Parus, but Parus faults Mintz for “shoddy, substandard” legal work performed in connection with an inter partes review (IPR) (“which assertion Mintz strongly denies”) that deprived Parus of infringement recoveries anywhere close to a presuit $1.042B estimate. Mintz’s complaint reports that those recoveries, at least those relevant to its claims, have been much lower.

The Federal Circuit has denied a “sixth urgent plea” from Ramey LLP attorneys William P. Ramey, III and Jeffrey E. Kubiak, together with former Ramey LLP attorney Susan S.Q. Kalra and Ramey LLP client KOJI IP LLC. That plea is perhaps somewhat less urgent given the representations made in a Ramey declaration just submitted in support of an application for pro hac vice admission to represent WirelessWERX IP LLC in the District of Delaware. Chief Judge Colm F. Connolly has set a hearing next month on the matter of Ramey’s admission there. Meanwhile, WirelessWERX IP has yet to update its corporate disclosure in light of assignment to Judge Connolly—and the dockets for several MISSED CALL, LLC cases also before Judge Connolly remain quiet.

Bulk distributions of assignment records have been sparse of late, as the USPTO apparently reworks the process by which the public has access to them. However, a review of recently recorded assignments via the agency’s new portal suggests that the most prolific monetization operation over the past year or two plans to keep on keeping on.

New Patent Litigation
|
|
In March of this year, Northern District of California Judge Araceli Martinez-Olguin granted an Oura Health motion to dismiss a declaratory judgment action filed by Samsung. Despite enforcement efforts undertaken against others in the smart ring space, the court ruled that the lack of an affirmative action directed at Samsung itself prevented the exercise of jurisdiction there. Now, Oura Health (Ouraring) has indeed sued Samsung (2:25-cv-01064), alleging in an Eastern District of Texas complaint infringement of eight patents through the provision of the “Galaxy Ring and its corresponding Applications, including the Galaxy Wearable Application and the Samsung Health Application”. The new case drops on the heels of Oura Health’s success before the International Trade Commission (ITC).

UMBRA Technologies (US) Inc. and UMBRA Technologies Ltd., a British Virgin Islands entity, have together filed another complaint, this one against Zscaler (2:25-cv-01063) in the Eastern District of Texas, where Fortinet and Palo Alto Networks (PAN) are already defendants. The UMBRAs target with four patents, three new to the campaign, the provision of “hardware and software products for network virtualization and related services”, including the Zero Trust Firewall and Zscaler Zero Trust Exchange products. A Western District of Texas case against Cisco has been stayed, while an Alice motion is pending in a District of Delaware suit against HP Enterprise (Juniper Networks).

Now characterizing itself as “a Texas corporation located in Harris County, Texas”, VIAAS, Inc.—previously identifying itself as a Delaware corporation based in California—has sued Vivint (2:25-cv-01048), a subsidiary of NRG Energy, for a third time. A 2022 case in the Western District of Texas was dismissed for lack of standing, the court identifying breaks in the chains of title for the two patents-in-suit. VIAAS tried again in late 2024, suing Vivint in the Eastern District of Texas. Vivint moved to dismiss on the same basis, and VIAAS—now pleading that counsel for Vivint “alleged a further assignment issue for one of the patents-in-suit”—voluntarily dismissed that case without prejudice. VIAAS now presents an order from a Texas state court that purports to fix the chains of title here.

At issue in the Western District of Texas complaint are features such as AI avatars, audio processing, and speech translation and display. Texas monetization firm Dominion Harbor Enterprises, LLC received a large portfolio of patents from Avaya, five of which are now in suit against NVIDIA.

Exclusive licensee Perceptix Technologies LLC has filed a second Central District of California case against Meta Platforms (8:25-cv-02390). Asserted here is a single patent—owned by Electronics and Telecommunications Research Institute (ETRI)—generally related to a “wearable mobile phone” with an electromyography (EMG) measuring unit. Perceptix targets the provision of “wearable communication devices”, including the Meta Orion and Meta Ray-Ban Display AR glasses. At issue is the included EMG Wristband, which allows users to “interpret hand gestures to use common smart phone apps”.

STT WebOS Inc has filed an Eastern District of Texas complaint against Verizon (2:25-cv-01053) targeting the provision of the Verizon Cloud platform and related services. Asserted are nine patents described as generally related to “communication networks, and more specifically, to web-based communications and multitasking”. After the filing of an amended complaint this past July, the only other defendant in this campaign, ByteDance (TikTok), is accused by the inventor-controlled plaintiff of infringing the same nine patents.

In Case You Missed It

In its remaining open case, HALEY IP LLC faces a fully-briefed motion to dismiss in which defendant Samsung (Harman International Industries) challenges the asserted claims of the sole patent-in-suit as ineligibly drawn to the abstract idea of “observing whether a driver is properly looking at the road”. Harman points District Judge Rodney Gilstrap to a previous invalidation in the Northern District of California of claims from a related patent. HALEY IP escaped that ruling when, per defendant Motive Technologies, “something happened that seemed strange at first”—and, given other more recent events, it looks as if HALEY IP might just be building another “escape”.
