    Mitch’s clients are most often corporations of various sizes and universities. Mitch’s corporate clients include traditional manufacturing companies and also companies specializing in the generation and licensing of intellectual property. More specifically, Mitch often works closely with a client’s inventors and in-house council or licensing officer to translate their ideas and disclosures into patent applications that best serve their interests. He very much enjoys discussions with inventors, often finding that he “speaks their language”. Mitch has received compliments from inventors and council for his technical and legal knowledge and attention to detail in the patenting process.

    Life Beyond the Law

    One of my favorite quotations comes from an ancient Roman playwright, Terentius Afer: “I am human. Nothing human is alien to me”. I am a curiosity-driven former scientist and engineer with special passions for singing, languages, physics, evolutionary biology, the game of baseball, and explaining esoteric scientific and technical ideas in everyday language. The practice of patent law allows me to combine my passions for technology, language, and teaching. When not practicing patent law I sing, occasionally conduct a choir, attempt to learn jazz piano, read, and play baseball catch with my son.
