Patent disputes over medical technology exert a significant influence on a company’s fortunes in the marketplace, and a recent decision by the U.S. Court of Appeals for the Federal Circuit reinforces yet again the importance of patent protection for device manufacturers. In a decision filed May 24, the Federal Circuit decreed that patents for catheters held by Teleflex Innovations were not rendered ineligible by what Dublin-based Medtronic plc had asserted was prior art, thus dealing Medtronic a blow in its efforts to have the five Teleflex patents in question rendered null.
