- As lawsuits over artificial intelligence and copyrights continue to unfold, two recent federal court decisions from the Northern District of California provide early insight—conflicting at times—into how judges will begin to draw the boundaries of “fair use” in AI training. In Bartz v. Anthropic PBC and Kadrey v. Meta Platforms Inc., the courts reached different outcomes on whether copying books to train large language models (“LLMs”) violates copyright law.

Understanding where your mark falls on this spectrum is critical to selecting and building a strong brand., Author, Understanding Trademark Distinctiveness: The Spectrum of Protection, JaburgWilk.com, 2025

Understanding the Basics, JaburgWilk.com, 2025

- The U.S. Supreme Court has ruled that Booking.com B.V., the owner of the hotel-reservation website of the same name, is entitled to register the mark BOOKING.COM with the United States Patent and Trademark Office (“USPTO”). In doing so, the Court rejected the USPTO’s nearly per se rule that adding “.com” to a generic term can never create a distinctive and registrable mark. The Court clarified that the determination of whether a term is generic depends on whether consumers perceive the term as generic., Generic.Nope: Supreme Court Deems BOOKING.COM a Distinctive, Registrable Mark, JaburgWilk.com, 2020
