WILMINGTON, Del. (AP) — A federal judge in Delaware has ruled that certain heart pacemakers sold by Medtronic Inc. do not infringe patents claimed by rival medical device manufacturer Boston Scientific Corp.
Ruling in a long-running dispute between the two companies, the judge granted a request by Minneapolis-based Medtronic for a ruling that certain implantable heart stimulators it makes do not infringe Boston Scientific patents.
But at the same time, the judge denied Medtronic’s request for a declaration that the patents claimed by Massachusetts-based Boston Scientific are invalid and unenforceable.
The patents involve specialized pacemakers capable of stimulating both ventricles of the heart to help increase its ability to pump blood.
