Mr. James N. Kallis | Attorney

James Kallis is an insightful patent attorney who provides his clients with high-quality intellectual property advice and a deep understanding of patent preparation and prosecution tasks.

James focuses primarily on domestic and foreign patent prosecution and preparation. He has written over one thousand patent applications for applicants ranging from Fortune 500 companies to small niche companies to independent inventors. James also performs patent analysis in which he has written non-infringement and invalidity opinion letters and conducted a multitude of novelty and state-of-the-art studies.

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. He is experienced in all aspects of U.S. patent prosecution including examiner interviews, appeals, petitions, reexaminations, and reissues. 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 regularly collaborates with foreign counsel in obtaining European, German, Chinese, Mexican, and Japanese patents. 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.

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.

James started his employment with Brooks Kushman as a law clerk while a full-time law student at Wayne State University. He then began practicing as an attorney with Brooks Kushman after passing the Michigan State Bar Exam.
