The Patent Trial and Appeal Board ("PTAB") issued Final Written Decisions regarding Cisco's U.S. Patent Nos. 6,377,577 ( the "'577 Patent") and 7,023,853 (the "'853 Patent") on May 25, 2017 and U.S. Patent No. 7,224,668 ( the "'668 Patent") on June 1, 2017. The PTAB found the '577 and '668 Patents invalid but upheld the validity of the '853 Patent. The Inter Partes Review ("IPR") proceedings were brought by Arista Networks in retaliation to Cisco's accusations of infringement brought in multiple venues, including at the U.S. International Trade Commission ("ITC"), which had just a few weeks earlier upheld the validity of these very same patents and determined that Arista infringed the '577 and '668 Patents, and issued exclusion and cease and desist orders accordingly.

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.
