By virtue of his 37 years’ experience in the US Patent and Trademark Office, Ian is able to provide clients with valuable advice as to the practices and procedures involved in the prosecution of patent applications, as well as post-grant proceedings before the USPTO. Ian also brings to the table his experience from representing clients in a large number of the now-replaced inter partes reexamination proceedings.

Ian’s practice focuses on patent prosecution, with primary emphasis on proceedings before the Patent Trial and Appeal Board, such as ex parte appeals and inter partes reviews, as well as appeals to the Court of Appeals for the Federal Circuit. Having served both as a patent examiner and vice chairman of the Board’s predecessor, the Board of Patent Appeals and Interferences, as well as an Administrative Patent Judge on that Board, he is well positioned to apply his knowledge and insight of how the Board operates and approaches various issues.

During his tenure at the USPTO, Ian also served as Chairman of the Board of Patent Interferences, in which capacity he was involved in deciding many patent interference proceedings. This gave him a thorough background in the conduct of inter partes proceedings before the USPTO, which he is able to put to good use for his clients.
