In Dawson v. Dawson, the Federal Circuit considered an unusual case with a question that often arises in interferences: when did the inventor invent the subject matter at issue. While the decision does not break new ground in the law of conception, it highlights the issues that can arise when an inventor changes employment before an invention has been reduced to practice.

The Invention at Issue

The invention at issue relates to methods of treating eye infections using topical azalide antibiotics. Dr. Dawson worked on the invention while he was at the University of California, San Francisco ("UCSF"), but did not file a patent application directed to the invention until he was at InSite Vision Incorporated. The basic question presented by this case is whether Dr. Dawson had conceived the invention while he still was at UCSF.

U.S. Government Backs Fair Use For AI Training In OpenAI Copyright Litigation

The U.S. government has filed a Statement of Interest of the United States of America under 28 U.S.C. § 517 in the Southern District of New York multidistrict litigation over OpenAI’s use of copyrighted works to train large language models. The filing appears to be the federal government’s first direct intervention in the wave of artificial intelligence (AI) training copyright cases, and it advises the court to treat model training (separate from use of AI to generate outputs) on copyrighted text standing alone as a highly transformative fair use under current law.

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.
