Smith & Nephew won a patent case filed against it after a British court overturned Kinetic Concepts Inc.’s infringement claims.

The British devices giant, which houses its endoscopy division in Andover, said the U.K. Court of Appeal deemed invalid all claims that it infringed a patent licensed to KCI with its Renasys-F negative-pressure wound therapy.

A lower court had slapped Smith & Nephew with an injunction barring sales of Renasys in Great Britain, but the appeals court overturned seven of the 10 infringement claims earlier this year.

The latest decision clears the final three claims and lifts the injunction, but Smith & Nephew still faces a similar suit Down Under, where KCI’s Australian division is pursuing a similar claim and succeeded in imposing another sales injunction.

And although Smith & Nephew won another infringement case related to the NPWT product in Germany in March, KCI said it planned to appeal that decision and its most recent setback in the U.K.
