Christopher (Chris) Kilner is an experienced patent attorney practicing in patent, copyright, trademarks, trade secrets, and litigation related to these areas. His particular focus is in drafting and prosecuting patent applications in the mechanical engineering and electrical arts, appealing cases to the Board of Patent Appeals and Interferences, drafting client requests for reexamination, rendering validity and infringement options for technical clients, and representing clients in all other aspects of patent prosecution from initial disclosure to issuance of a patent. While working at the firm, Mr. Kilner also assisted in successfully defending a group of defendants in a multi-district patent infringement case, and was deeply involved in preparing pleadings related to claim interpretation, non-infringement, and patent invalidity. He also drafted portions of the Appellee’s Brief that successfully upheld the District Court’s decision before the Court of Appeals for the Federal Circuit (CAFC).
Mr. Kilner joined the firm in 1999 after working as a Patent Examiner for ten years at the United States Patent & Trademark Office, the last five years as a Primary Examiner with signatory authority.
During his tenure with the Patent Office, he issued in excess of 700 patents, trained new examiners in regular, RCE, appeal, reissue, reexamination, and PCT practice. His examining duties included checking applications for form, searching prior art, determining patentability, and preparing written communication to the applicant in a timely manner. Mr. Kilner examined applications in various technologies, including refrigeration (Class 62: superconductor refrigeration, semiconductor chip cooling, biological cryopreservation, cryogenic air and hydrocarbon distillation, and cryogenic removal of xenon and krypton from nuclear plants) and heating and drying (Classes 423, 34, 110, 122, 236, 237, and 126 including: kilns, semiconductor diffusion furnaces, wafer boats, and IPA vapor dryers).
Mr. Kilner began his career at the Naval Surface Warfare Center in White Oak, MD, initially as a co-op student trainee, and after graduation as a Mechanical Engineer where he prepared test plans, managed tests, collected and analyzed data, and published results supporting anti-submarine and special warfare (SEAL teams).
