On June 10, 2025, Wilson Sonsini secured a complete defense verdict from a Los Angeles jury in ReactX LLC v. Google LLC.  ReactX sought $1.3 billion in damages, alleging that Google breached a series of contracts by misusing ReactX’s confidential technology to build two of Google’s most successful digital advertising products. ReactX originally brought the case as one for trade secret misappropriation, but just two weeks before trial, it voluntarily dismissed its trade secret cause of action. The court further trimmed ReactX’s lawsuit in response to nonsuit motions brought by Wilson Sonsini, ruling that Google was bound by only one of the contracts asserted by ReactX and dismissing ReactX’s cause of action for breach of the implied covenant of good faith and fair dealing. After a six-week trial featuring 17 witnesses, the jury completely vindicated Google on ReactX’s remaining cause of action for breach of contract.

The Wilson Sonsini team representing Google in the matter was led by partners Colleen Bal, John Flynn, Tait Graves, Josh Baskin, and Lucy Yen, and included Andrew Alderette, Stephanie Cheng, Kayla Dessel, Katherine Ericson, Celine Liu, Sachli Nayeri, Courtney Reed, Matt Donohue, Doug Brockmeier, Sissel Browder, Shannon Hill, and Pamela Sandillo.
