Executive Summary
S&N's debut of a foam dressing kit for negative pressure wound therapy, announced Dec. 11, prompts competitor Kinetic Concepts to sue S&N for infringement of three patents licensed to KCI from Wake Forest University. The San Antonio federal court case is set for trial in October 2009. The latest charges add to previous KCI infringement claims that stem from before S&N's 2007 acquisition of negative pressure wound therapy device maker BlueSky Medical (1"The Gray Sheet" May 14, 2007, p. 16). S&N notes that its wound care customers will now be able to choose between gauze or foam as a wound interface for its NPWT treatment.
