Thank you so much to Irene Calboli for hosting the 10th International IP Roundtable. It was two days of intense and energizing discussion that showcased the expertise and deep knowledge of this great group of colleagues and friends. (Plus, there was a giant sparkly cowboy hat.)

A rare appellate report (through the MPIA because the WTO Appellate Body is still on hold) in a TRIPS case, this one about the use of anti suit injunctions in SEP cases in China. My initial take on it: ipkitten.blogspot.com/2025/07/gues...

Enjoyed taking my W&M patent law class for arguments at the Federal Circuit, then having them meet with a judge from the Federal Circuit & one from the Court of Federal Claims.
Highlights were one judge referencing Seinfeld (O’Brien ep) & another working in an 867-5309/Jenny hypo on 101 arguments.

Hello, Bluesky! I've been lurking for a bit, but this seems like a good place to be. I plan to post some balance of patent law musings, puns, and cute dog photos, in whatever proportion the audience cares to see.
