Through an affiliate relationship with Sorge & Associates, Keith partners with Arthur Chapman and its clients to provide robust intellectual property representation with an emphasis on patent litigation. His experience in working for clients in federal courts around the country and in the Judge Advocate General’s department (JAG) in the U.S. Air Force, serves clients well.  

Backed by this experience, clients turn to Keith for counsel on protecting their intellectual property portfolios and how best to seek redress when infringement of that property occurs. Keith’s extensive litigation experience covers a wide-range of industries. Businesses large and small rely on Keith to keep pressure on appropriate parties, striving to reach the best possible result for clients. International cases are not foreign to Keith either. A recent large case involved the representation of a United States-based business in a patent infringement/unfair competition case against a large Chinese toy manufacturer. The case resulted in a default judgment and has gained national attention.
