    I endorse this lawyer's work. He is diligent, experienced, and has the unique skill of understanding the legal concepts in patent and other intellectual property matters, and also the scientific understanding and experience (trained chemical engineer). He communicates well with people, and exercises good judgment, thus adding to his effectiveness. I would not hesitate to use Mike for any IP matter
