Craig Thorner is an inventive whiz when it comes to video game gizmos, but he hasn’t had much luck with lawyers.

In May, he sued New Jersey’s premier intellectual property boutique, Lerner David Littenberg Krumholz & Mentlik in Westfield, alleging a breach of duty to him in negotiations over licensing of game-control technology. The suit also claims that a Sony Corp. subsidiary infringed Thorner’s patents.
