" U.S. and foreign patents have been issued to third parties in the same fields as some of our product candidates........ Although to date we have not been subject to any infringement actions, we have been approached by third parties with respect to infringement claims."

" In this regard, we have received correspondence from a third party that alleges that certain of our compositions and methodologies fall within the scope of patents owned by this individual. Although we do not believe that these patents seriously harm our ability to develop and commercialize our products, we cannot be certain of this."
