Kinetic Concepts (KCI), a medical technology company that discovers, develops, manufactures and markets therapies and products for the wound care, tissue regeneration and therapeutic support system markets, said that the Court of Appeal of England and Wales has upheld the validity of important claims of two KCI patents relating to negative pressure wound therapy (NPWT).

The court also found that NPWT products marketed by Smith & Nephew infringe one of the patents.

In June 2010, the High Court of Justice Chancery Division, Patents Court found that Smith & Nephew’s Renasys NPWT products infringe valid claims of two KCI patents.

The present ruling upholds the High Court’s ruling as it related to infringement of an important claim of European Patent No. 0853950.

San Antonio, Texas based KCI Active Healing Solutions business global president Mike Genau said that this is not just a victory for KCI, it is also a victory for patients and the health care community that benefit from safe, clinically proven products.

“Patient outcomes and safety remain our primary focus. We’re committed to helping our UK customers immediately transition from infringing products to VAC Therapy,” Genau said.
