A: According to the United States Patent and Trademark Office (USPTO), the original patent 5931468 expired on August 3, 2016, 20 years after the filing date. The reissued patent RE-38666 was also granted for a term of 20 years from the filing date of the original patent, which would have expired on April 3, 2018. Therefore, neither patent is currently active or enforceable.
