A weekly summary of the precedential patent-related opinions issued by the Court of Appeals for the Federal Circuit and the opinions designated precedential or informative by the Patent Trial and Appeal Board.

Nature Simulation Systems Inc. v. Autodesk, Inc., No. 2020-2257 (Fed. Cir. (N.D. Cal.) Jan. 27, 2022). Opinion by Newman, joined by Lourie. Dissenting opinion by Dyk.

NSS sued Autodesk for infringement of two patents related to methods of packaging computer-aided data for three-dimensional objects. The district court held a claim construction hearing and ruled that the asserted claims are invalid for indefiniteness under 35 U.S.C. § 112(b).

The Trademark Scam Field Guide: Look-Alike Filing Sites, Fake USPTO Notices, And How To Get Out If You’ve Been Caught

A business decides to file a trademark. Someone on the team searches for a familiar online legal-services brand, clicks the first result, and lands on a site with a similar-sounding name, a polished design, five-star reviews, and a low flat fee. The application gets filed. Months later the business learns the “service” was not who they thought it was, the filing was signed by someone with no authority to sign it, and the USPTO has suspended the application along with hundreds or thousands of others from the same shop.

Is This Real? Navigating AI Impersonation Under New And Existing Laws

Is this AI-generated, or is it real? As generative AI tools have become increasingly capable of creating realistic images, videos, and audio, they have also made it easier to impersonate real people without their consent. In response, states are increasingly adopting laws that impose civil and criminal liability for certain AI-generated content that replicates an individual’s identity, likeness, voice, or other personal attributes.
