The Firm



Patent infringement and business disputes have become increasingly contentious over the past decade.  But even with this increased contentiousness, most firms continue to follow a formulaic approach to every case.  At Caldwell Cassady & Curry, we critically examine these formulaic approaches, identify vulnerabilities, and outflank our adversaries.
