ConforMIS Files for Interference Proceeding Against Imperial Innovations Group

Burlington, Mass. – March 21, 2012 – ConforMIS, Inc. filed documents to initiate an interference proceeding in the United States Patent and Trademark Office involving a patent application held by Imperial Innovations Group. The subject patent application, US 2011/0218635A1 entitled "Modular Knee Implants," lists Andrew Amis, Robert Wozencroft, and Justin Cobb as inventors. Imperial Innovations Group, an entity associated with the Imperial College London, recently announced a license of patented technology to Stanmore Implants in addition to a $4 million investment in the company to develop that technology, including the patient-specific Savile Row Unicondylar Knee implant.

ConforMIS believes that it was the first to develop this technology. ConforMIS President and CEO, Philipp Lang, MD, stated, "ConforMIS strongly disagrees with the recent claim in a press release issued by Stanmore and Imperial Innovations Group that they are developing the 'world's first fully personalised early knee replacement surgery system,' and ConforMIS has filed papers that will help set the record straight."

David Cerveny, General Counsel and Senior Vice President of Intellectual Property at ConforMIS added that, "ConforMIS technology related to patient-specific implants and instruments has been in development for more than a decade and ConforMIS has a significant patent portfolio protecting that technology. With this filing, ConforMIS has essentially requested that the United States Patent and Trademark Office make a determination that ConforMIS inventions in the area predate the work that Imperial Innovations and Stanmore are presently undertaking."
