Court rules against Boston Scientific in patent spat
Johnson & Johnson's Cordis unit won a round Thursday in its battle with Boston Scientific Corp. over a stent patent as the US Court of Appeals for the Federal Circuit ruled in its favor, overturning a lower court ruling.
Boston Scientific, the Natick-based medical device maker, had accused Cordis of infringing a patent for an expandable stent, and a jury in the US District Court for the District of Delaware agreed.
That court also denied Cordis' motion for a new trial.
But Cordis appealed the lower court ruling and won the latest skirmish in the patent dispute.
"The (lower) court erred as a matter of law in failing to hold the '536 (stent) patent to have been obvious," the appeals court said. "Obviousness" is grounds for stripping Boston Scientific of the patent.
"We reverse the judgment," the appeals court said.
Stents are tiny mesh tubes used to prop open heart arteries that have been cleared of blockages and are important products for both companies. (Reuters)
