Gore-Tex maker to pay Medtronic in patent settlement

The maker of that stretchy, waterproof Gore-Tex fabric has agreed to pay Medtronic an undisclosed sum to settle a patent infringement lawsuit.

Medtronic sued W.L. Gore & Associates in 2006. Gore-Tex is the Maryland-based company’s best-known product, but it also sells medical devices and surgical fabrics, among other technologies.

The patents in question cover a method for restraining self-expanding medical devices made out of nitinol, an unusual “shape-memory” metal used in Medtronic transcatheter heart valves.

Medtronic said it expects to record a one-time gain from the settlement in its second-quarter results, but terms of the settlement are confidential.
