John’s engineering background, coupled with over two decades of patent prosecution, place him in a unique position to help clients.  John spent 15 years as an electrical engineer performing research and development work for General Dynamics Pomona Division in California and system design work for General Dynamics Land Systems Division in Michigan.  His work ranged from semiconductor chip design and fabrication to vehicle power distribution.  While in Michigan, John was introduced to the world of patent law by his father.

John’s engineering experience has given him the ability to easily communicate with inventors at technical levels in a wide variety of subjects in the electrical and mechanical arts.  John has worked cases covering topics such as automotive electronics, digital video chip designs, Global Positioning System utilization, data storage, computer components, cryptography, networks, telecommunications, microwave circuitry, embedded testing and solid-state drives.  Due to his experience in patent law, John is able to work well with the US Patent and Trademark Office to obtain issued patents.  Over the last 15 years, John has obtained over 500 U.S. patents for his clients.  John also has experience working with foreign clients in a variety of countries, including Canada, China, India, Italy, Japan, Russia, Taiwan and the United Kingdom.  John’s experience as a Patent Attorney allows him to focus his work product on meaningful Intellectual Property for the clients.  John has written and prosecuted applications for companies such as Cypress Semiconductor, LSI Corporation, Ambarella and Integrated Device Technology.  One of his more notable cases was ranked second by Ocean Tomo, LLC on a list of top 10 recently issued patents in their 2009 publication Patent Analytics Industry Focus: Health Care.

John enjoys working with inventors on state-of-the-art inventions.  Seeing innovative technology before it is available helps keep his engineering curiosity satisfied.  He is also proud of his success rate before the United States Patent and Trademark Office.  The experience of obtaining a newly issued patent is similar to seeing a new chip design come to life.
