Chrimar Systems, Inc. v. ALE USA Inc., No. 18-2420, Courtroom 402

Chrimar sued ALE alleging that ALE’s products infringed four of Chrimar’s patents.  The district court found that the patents were valid and awarded damages and ongoing royalties to Chrimar.  ALE appealed, but did not challenge validity or ongoing royalties.  During the pendency of the district court action, third parties petitioned for inter partes review of the four patents asserted against Chrimar.  After the completion of briefing on appeal, but before the Federal Circuit issued its decision, the PTAB issued Final Written Decisions finding that all of the challenged claims were invalid.  Chrimar has appealed each of the Final Written Decisions and those appeals are currently pending before the Federal Circuit.  The Federal Circuit subsequently issued its opinion vacating the district court’s claim construction with respect to one of the four asserted patents (U.S.

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.

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.

Federal Court Orders Rebel Creamery To Redesign Packaging And Disgorge $23.8 Million In Van Leeuwen Trade Dress Case

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.
