Brita LP v. ITC, No. 24-1098, Courtroom 201, Panel B

This appeal arises from the ITC's reversal of an ALJ ruling that certain imported water filters infringed Brita's patent (U.S. Patent No. 8,167,141) and violated Section 337. Brita's '141 patent relates to gravity-fed water filters for removing lead contaminants in drinking water. In the underlying ITC proceeding, the ALJ determined that the claims-at-issue were valid and infringed. The Commission reversed the ALJ's ruling and found those claims invalid under 35 U.S.C. § 112 for lack of written description, lack of enablement, and indefiniteness. Brita appealed to the Federal Circuit.

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.

Federal Circuit Affirms Written Description Support, Vacates Mooted Non-Obviousness Finding

The Federal Circuit affirmed a district court's validity findings for Exelixis's Salt Patents related to its cancer drug Cabometyx, holding that disclosure of chemical name, formula, and crystalline structure provided adequate written description support. However, the Court dismissed MSN's appeal and vacated the non-obviousness finding for the '349 Patent after Exelixis unilaterally dismissed its cross-appeal, preventing MSN from opposing the adverse judgment.

Who Is A “Consumer?” The Supreme Court Takes Up The Video Privacy Protection Act

The Supreme Court will decide whether subscribing to any good or service from a video provider—such as a newsletter—makes someone a "consumer" under the Video Privacy Protection Act, or whether only subscriptions to audiovisual content qualify. The case involves allegations that a website disclosed a user's video-viewing history through Facebook tracking pixels after the user signed up for an online newsletter, creating a circuit split on how broadly the VPPA's consumer protections should apply.

A New York federal court ruled that Rebel Creamery intentionally copied Van Leeuwen Ice Cream's distinctive packaging, resulting in a $23.785 million disgorgement order and mandatory redesign. The decision demonstrates how trade dress protection can extend to overall packaging aesthetics when individual elements combine to create a unique commercial impression, even when those elements might be commonplace in isolation.
