(248) 226-2739

  • Overview
  • Background

Practice Areas

James focuses primarily on domestic and foreign patent prosecution. He enjoys learning about technology and has obtained hundreds of patents in various technologies including electronics, computers, data storage systems, telecommunications, wireless communications, business methods, and automotive assemblies (convertible roof tops, remote keyless entry systems, steering columns, and windshield wiper systems). James has a great understanding of a wide array of patent office procedures from handling a multitude of different types of patent preparation and prosecution tasks. In addition to preparing and prosecuting his own patent applications, James is especially adept at prosecuting patent applications based on previously filed foreign patent applications. He has successfully obtained dozens of favorable patent application appeal decisions from the Board of Patent Appeals and Interferences at the U.S. Patent Office. He also has been successful in reexamination practice and oral argument in front of the Board. James appreciates the importance of patents to his clients and handles patent prosecution with this appreciation in mind. One patent that James prosecuted (U.S. Patent No. 6,785,825 relating to technology for reducing computer software piracy) was successfully enforced by Brooks Kushman P.C. along with another patent resulting in a $133 million jury verdict that was affirmed by the Federal Circuit (z4 v. Microsoft Corporation and Autodesk, Inc.). From this experience, James understands what it is like to be deposed and testify during a trial and to have patents scrutinized by opposing counsel and trial and appeal courts. James applies this unique perspective in his patent preparation and prosecution practice.
