Last week, the U.S. Court of Appeals for the Federal Circuit issued an opinion in Jiaxing Super Lighting Electric Appliance Co. v. CH Lighting Technology Co., No. 23-1715 (July 28, 2025), partially undoing a district court win for LED-lamp maker Super Lighting and sending the case back for a second round.

Super Lighting sued CH Lighting for infringing three patents directed to LED tube lamp technology. Before trial, CH Lighting admitted to infringing two of the patents (the "tube" patents), but challenged them as anticipated under the AIA's on-sale bar. The case was tried in the Western District of Texas, where the district court excluded some of CH Lighting's evidence and granted judgment as a matter of law (JMOL) that the tube patents were not invalid. The jury found the third patent (the "circuit" patent) infringed and not invalid and awarded damages for all three patents. CH Lighting appealed.

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.
