Ryan Yagura, Chair of the Firm’s Intellectual Property and Technology Practice, steers some of the world’s leading technology companies through their complex patent infringement matters. An accomplished trial litigator, Ryan has extensive experience leading offensive and defensive cases in District Court and ITC litigation. This includes patent infringement, trade secret misappropriation, breach of technology licensing or development contracts, standard setting, antitrust, and other technology-intense claims. Ryan has also practiced before the USPTO in inter partes review (IPR) proceedings.

Prior to attending law school, Ryan worked as an engineer at Intel Corporation on the Pentium microprocessor and at Read-Rite Corporation on the development of thin film magnetic recording heads. Among other accolades, the Daily Journal named Ryan to its list of the Top 75 Intellectual Property Litigators in California, and Law360 featured Ryan in its publication of intellectual property lawyers to watch. Clients too praise Ryan’s legal ability and call him a “pleasure” to work with. (IAM Patent 1000)
