Victor Cheung


Victor Cheung joined Ropes & Gray in 2017 as an associate in the intellectual property litigation group. Prior to joining the firm, Victor was an associate at an IP boutique law firm in Northern Virginia. There, he gained valuable experience drafting and prosecuting patent applications, but focused his practice on post-grant patent procedures at the Patent and Trial Appeal Board (PTAB), primarily with respect to inter partes reviews (IPRs).

Victor’s practice involves clients in a variety of technologies, including electronic displays, wireless communications, integrated circuits, audio devices, computer networking, computer software, and other consumer electronics.

Before law school, Victor was a patent examiner at the United States Patent and Trademark Office (USPTO), where he examined patent applications related to games of chance and amusement devices (electromechanical, video, and computer gaming), in addition to applications related to educational demonstrational materials.
