All of our opioid product candidates utilizing Aversion® Technology (with or without niacin) are encompassed by two issued U.S. patents, which in combination with our anticipated product labeling and drug product listing strategies are anticipated to provide our opioid products licensed to King with protection from generic competition through the expiration of our patents in 2025.Impede ™ Technology We have developed a pseudoephedrine hydrochloride (PSE) tablet product candidate utilizing our Impede ® Technology. Impede™ Technology utilizes a proprietary mixture of functional inactive ingredients intended to limit or impede extraction of PSE from the tablets for use as a starting material in producing the illicit drug methamphetamine. The unique mixture of inactive ingredients in the Impede ® PSE product candidate are generally recognized as safe. We sponsored an independent pharmaceutical laboratory test of our Impede ™ PSE tablets compared to Sudafed®* brand PSE tablets in an attempt to extract PSE from 100 x 30 mg tablets for conversion to methamphetamine using what we believe to be the three most commonly used conversion processes. The results of these tests demonstrated that while PSE was readily extracted from Sudafed® tablets, Impede ® PSE effectively impeded the extraction of the PSE for conversion into methamphetamine. We are evaluating commercialization strategies for our Impede ® PSE Tablets. *Sudafed® is a registered trademark of Johnson and Johnson Corporation Tender Offer by Pfizer, Inc. to Acquire All Outstanding Shares of King Pharmaceuticals, Inc.
