Tyler Knox guides clients on best practices to litigate intellectual property disputes.

Prior to joining Arnold & Porter, Mr. Knox was an intellectual property associate at a boutique IP law firm. He relies on his past engineering experience as a professional engineer (PE) and project management professional (PMP) to help clients navigate high-technology patent litigation disputes in federal court and post-grant proceedings before the United States Patent and Trademark Office (USPTO). In past matters, Mr. Knox defended mobile phone and gaming technology companies in patent infringement lawsuits brought by industry competitors and non-practicing entities seeking to monetize their patent portfolio. Years of experience as a Primary Patent Examiner at the USPTO helped him defend a global toymaker and its US retailers against a plaintiff's patent infringement claims by uncovering the plaintiff's inequitable conduct before the USPTO when prosecuting its patent. For that same toymaker, Mr. Knox helped file and managed an investigation with the International Trade Commission to exclude the importation of infringing and unsafe versions of one of its toys.
