Update UK Trademark Caselaw – Doctrine of Postsale Confusion – Interview With Joshua Cunnington – Lutnick Suggests 5% Patent-Value Fee – UPC Court of Appeal Does Not Endorse Referral to the CJEU – IP Fridays Podcast – Episode 166

I am Rolf Claessen and my Co-Host Ken Suzan and I are welcoming you to episode 166 of the IP Fridays Podcast. Today’s interview guest is Joshua Cunnington, who is Managing Associate at Stephenson Harwood in the UK. My Co-Host Ken Suzan talks with him about an update on Trademark Caselaw in the UK, e.g. the Doctrine of Postsale Confusion.

Before we jump into the interview, I have news for you

The U.S. Patent and Trademark Office (USPTO) has removed more than 52,000 fraudulent trademark applications and registrations from the register. On August 6, 2025, the agency sanctioned a foreign filing firm that had submitted large numbers of applications using forged signatures, fake attorney identities, and manipulated specimens of use.

Reports from the United States describe an unusual funding proposal: according to the Wall Street Journal, Commerce Secretary Lutnick is considering imposing a levy of 1% to 5% of a patent’s value on patent owners. This possible “patent-value fee” would raise additional budget funds. Details remain unclear, and the idea is already stirring controversy in the IP community.

On August 4, 2025, the USPTO’s patent division issued new guidance on the patent eligibility of AI and software inventions. The “Kim Memo” stresses that examiners should not hastily label software-related claims as abstract ideas. Instead, all claim elements should be evaluated together; where eligibility is uncertain, no Section 101 rejection should be made absent clear exclusionary grounds.

In its first costs decision, the Unified Patent Court (UPC) Court of Appeal dismissed Expert klein’s appeal and declined to refer questions to the CJEU. The judges confirmed that applications for costs must be filed no later than one month after judgment and saw no reason to seek guidance from the CJEU. It seems that the Court of Appeal generally rejects the idea that decisions of the UPC could potentially be brought before the CJEU.
