Kramer Alberti Lim & Tonkovich LLP, with co-counsel MoloLamken LLP, won an important victory for client Express Mobile in the Federal Circuit Court of Appeals in a patent infringement case against Meta, Google, and eBay.

The Federal Circuit’s decision overturned an earlier PTAB ruling, correcting the claim construction. The matter will now continue in the PTAB on remand and then return to the district court for continuation of Express Mobile’s patent enforcement cases.

“Steve Rempell, a well-respected, former IBM senior scientist, and the founder of Express Mobile and its lead inventor, was a genius who invented fundamental techniques used today by most major technology companies to build and operate their web sites using browser-based engines,” explained Kramer Alberti partner Rob Kramer, who is lead counsel for Express Mobile.

In a statement to Law360, Mr. Kramer stated, “Express Mobile’s ‘168 patent is valid and an important technological improvement. And the tech companies who have been widely using this technology will be held to account for doing so.”

The case is Express Mobile v. Meta Platforms, Inc. et al., Case No. 23-1646 (Fed. Cir. 2025. Meta (Facebook) is represented by Cooley LLP, Google is represented by Paul Hastings LLP, and eBay is represented by Orrick LLP.
