- In today’s digital-first world, trademarks are more visible—and vulnerable—than ever.

- 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.

- In trademark law, distinctiveness is key. The more distinctive a mark, the stronger its legal protection—and the easier to register and enforce the mark. Trademark law classifies marks along a spectrum of distinctiveness, ranging from inherently protectable to completely un-protectable. 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

- A trademark is a word, phrase, symbol, or design—or a combination of these—that identifies and distinguishes the source of goods or services of one party from those of others. Essentially, a trademark is your brand’s identity in the marketplace. It allows consumers to recognize and trust the products or services you offer., Author, What Is a Trademark? Understanding the Basics, JaburgWilk.com, 2025
- Cybersquatters often exploit brand owners by demanding a large payment for a domain name that is similar to the brand owner’s trademark.

- 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
