Kat nap

In case last week was more naps than notes, the IPKat kept track. Here’s what you might have missed.

Copyright

Söğüt Atilla-Aydın explored the Supreme Court’s take in Cox v Sony, stepping into the long-running tension between copyright enforcement and ISP responsibility, and analyzing where the line is drawn between awareness of infringement and actual liability.

Eleonora Rosati unpacked the CJEU’s long-awaited Pelham II judgment, taking a closer look at the notion of “pastiche” under EU copyright law and how the Court approached its boundaries in the context of creative reuse and artistic dialogue.

Georgia Jenkins analyzed a dispute born from a photoshoot gone wrong, exploring how publicity rights, artistic expression, and trademark arguments collided, while the court navigated the fine line between creative work and commercial use.

Patents

Claire Gregg leaned into Australia’s ongoing “best method” flip-flop, unfolding the latest turn in the courts’ approach to divisional applications and how this back-and-forth continues to keep applicants (and their advisers) on their toes.

Rose Hughes might have posted a few days early for 4/20, as she explored a decision on cannabinoid-producing yeast and how far sequence identity percentages can stretch -when paired with the right functional definitions- before running into added matter or sufficiency issues.

Rose Hughes also took a data-driven turn on AI in the patent profession, challenging common scepticism by looking at how far LLMs have actually come, especially when it comes to handling complex, long-form reasoning tasks.

Trademarks

Katfriend Maria Cristina Michelini explored how Italy has stepped into the influencer space, detailing a growing web of rules that increasingly treats influencers less like casual content creators and more like regulated media actors.

Fordham IP Conference

Sophie Fulara reported back from Fordham (Report 4), continuing the series with a session on life sciences and healthcare innovation, touching on clinical trials, plausibility, SPCs, and shifting patent strategies across jurisdictions.

Ilze Ambrasa covered a session on trade secrets (Report 5), exploring their interplay with patents, the impact of AI, and the growing importance of confidentiality and employee practices.
