Mark Litman was Senior Intellectual Property Counsel at a Fortune 500 Company and had primary responsibility for the Intellectual Property for businesses with more than a billion dollars a year in sales.
 
After going into private practice, many of his corporate clients sought out Mark to do their work. Individual inventors that went to new companies also continue to seek out Mark A. Litman & Associates to handle all of their IP needs, including Patent Application drafting, prosecution and appeals; Patent Licensing; Validity and Infringement Opinions; litigation management; and general IP counseling.

Mark A. Litman & Associates have extensive international prosecution experience in a wide range of technologies and can assist in all forms of domestic and international IP filings, including the Patent Cooperation Treaty applications, European patent Applications, Eurasian Patent Application filings, and individual country national filings throughout the world.

Officers and scientists in the companies who are our clients include many individuals who have worked with Mark A. Litman for 5 to 25 years and have come to depend on the individual attention given to them. The majority of new business to our firm comes from client referrals rather then referrals from law firms. There is no better recommendation of our work than this confidence.
