Teladoc, Inc. (NYSE: TDOC), the nation’s first and largest telehealth provider, today announced the U.S. Patent and Trademark Office (USPTO) has invalidated the major elements of a telemedicine patent held by American Well Corporation on the basis that they were not patentable because American Well did not invent them. The USPTO took this action at the request of Teladoc. At issue before the USPTO were the same elements of the American Well patent that a Massachusetts federal court declared invalid earlier this year on a separate basis.
