Samsung's $350M security request; Nissan settles with Broadcom; Nokia wins against ASUS in Brazil; more from U.S., Europe, China

1) Premium: Samsung requested €295M ($350M) security for enforcement of Germany-wide patent injunction against its phones and tables

Samsung defended itself in that case (barring a successful appeal), so there will be no need for enforcement security. But the collateral demand is interesting in light of a German injunction ZTE obtained against Samsung last week.

2) Free: Nissan settles patent dispute with Broadcom

Broadcom is still embroiled in litigation with Renault (which is under enormous settlement pressure as an injunction is being enforced) and Hyundai.

We had previously mentioned on LinkedIn that there were signs of a settlement.

3) Premium: Amazon latest target in AI voice tech patent infringement campaign: sued in ITC, Eastern District of Texas

AI software firm Cerence has filed three complaints against Amazon in the United States International Trade Commission and the Eastern District of Texas over the alleged infringement of voice tech-related patents. The company already sued Apple and Samsung over similar technologies, reaching a successful $49.5 million settlement with the latter last year.

4) Free: Appeals court upholds Nokia’s Brazilian AVC SEP injunction against ASUS, throws out part of expert report with implications for Acer case

ASUS hoped to get Nokia’s Brazilian preliminary injunction lifted by an appeals court, but the PI remains in force and an expert report favoring ASUS’s cause has been deemed unreliable. That also affects a case against Acer.

5) Premium: BREAKING: USITC orders import ban on Innoscience products over infringement of Infineon gallium nitride patent

China’s Innoscience will be prohibited from importing its infringing products into the U.S. market – though the multi-jurisdiction battle with Infineon looks set to continue.

6) Premium: Urgency analysis of UPC PI motions can involve foreign product presentations, conversations with rivals at trade shows: two new rulings

The UPC’s holistic approach to the urgency requirement for preliminary injunction requests cuts both ways. Patent holders seeking to enforce their right must be prepared to satisfactorily answer certain questions related to urgency.

7) Premium: District judge opens door to rare “reverse doctrine of equivalents” defense in medical device dispute

The judge’s order came amid long-running litigation between Maquet and Abiomed in the United States District Court for the District of Massachusetts over intravascular blood pump technologies.

8) Premium: Lose three validity battles, win the infringement war? Microsoft’s CNIPA record against Newman’s GUI patent

A long-running Chinese touchscreen patent dispute between Newman Infinite and Microsoft has now reached China’s Supreme People’s Court, after the latter failed in four patent invalidation attempts. But the record is less one-sided than it currently appears to be.

9) Premium but free summary: UPC Lisbon LD: ASUS owes Ericsson damages for six years of infringing semiconductor patent in eight countries; PI was denied in 2024

Ericsson and ASUS are embroiled in multijurisdictional litigation. The most important showdown so far will be a preliminary injunction hearing to be held by the UPC’s Milan LD on Friday.

10) games fray (free): Nintendo lost $40M on litigation between April 2025 and March 2026: how much of that is related to Palworld?

The annual report does not specify what litigation(s) is/are responsible for most of that amount. A recent patent settlement could account for a large chunk of it.
