Precedential Federal Circuit Opinions

  1. SEABED GEOSOLUTIONS (US) INC. v. MAGSEIS FF LLC [OPINION] (2020-1237, August 11, 2021) (MOORE, LINN and CHEN) Moore, Chief Judge. Vacating final written decision of the Patent Trial and Appeal Board. The Board found, based entirely on extrinsic evidence, that "fixed" had a special meaning in the relevant art at the time of the invention: "not gimbaled." The Court held that, if the meaning of a claim term is clear from the intrinsic evidence, there is no reason to resort to extrinsic evidence. Based upon the intrinsic evidence, the word "fixed" in the claims carried its ordinary meaning, i.e., attached or fastened. Thus, the intrinsic evidence as a whole supported an interpretation of "geophone internally fixed within [the] housing" that did not exclude gimbaled geophones.

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.
