Through October 31, 2020, the Federal Circuit decided 787 PTAB appeals from IPRs and CBMs.  The Federal Circuit affirmed the PTAB on every issue in 578 (73.44%) cases, and reversed or vacated the PTAB on every issue in 104 (13.21%) cases.  A mixed outcome on appeal, where at least one issue was affirmed and at least one issue was vacated or reversed, occurred in 77 (9.78%) cases.

The court also dismissed 28 (3.56%) appeals without rendering a decision on the merits.  Dismissals may occur, for example, where the Federal Circuit determines that it does not have jurisdiction to hear an appeal, such as in certain appeals from PTAB institution decisions.

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.

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.

The Trademark Trial and Appeal Board's precedential decision in In re Everwise Credit Union examines whether a credit union's use of its mark constituted bona fide commercial use or merely token use designed to reserve trademark rights. The case centers on whether Everwise Credit Union had actually used its mark in commerce by the deadline to file its Statement of Use, or whether the mark's appearance on its website was simply a placeholder for a future rebrand that occurred two months later.
