The firm’s most prominent tracked case is Ironburg Inventions Ltd. v. Valve Corporation. In this litigation, BHW partner Joshua C. Harrison represented defendant Valve against claims of patent infringement related to video game controller technology. The case involved parallel IPR proceedings at the PTAB and a jury trial in the Western District of Washington.

The verdict and subsequent appeals addressed significant legal issues, including the scope of IPR estoppel. Key litigation partners include Reynaldo C. Barceló, who has experience as lead counsel on patent issues for major technology companies, and Joshua C. Harrison, a Stanford Law-educated Ph.D. in mechanical engineering with a focus on patent litigation and PTAB proceedings.
