Judge rules kinetic concepts' patents invalid
from The Wall Street Journal (subscription)
Kinetic Concepts Inc.'s shares slumped after a judge rendered invalid two key patents the medical-technology company has used to defend its wound-therapy franchise. The ruling by the U.S. District Court for the Western District of Texas effectively overturns a jury verdict from March that found U.K.-based medical-device maker Smith & Nephew PLC had infringed the patents. That case involved Smith & Nephew's Renasys products and two patents owned by Wake Forest University in Texas and licensed to Kinetic and included damages of $1.2 million. Kinetic said it will continue to analyze the court's ruling and assess its next steps, including an appeal.
