Mr. Schaefer devotes much of his time on contested patent matters in the U.S. Patent and Trademark Office, and on licensing and other contractual agreement matters.

Mr. Schaefer is a frequent lecturer on patent and licensing topics all over the world. He has a specific expertise on a company’s patent strategy vis-à-vis competitors, involving patent enforcement actions in US and foreign courts and patent validity challenges in the US and foreign patent offices, and has lectured on strategy topics in that area on several occasions. He has also lectured on topics related to patent licensing matters, and has specific expertise related to clinical support agreements for the testing and development of medical devices.

Although Mr. Schaefer represents some large companies, he also enjoys working with start-up companies in the medical device area.
