Of the three patents-in-suit that were the subject of the prior Texas case, TPL has removed one of them from this case by choosing not to assert it (U.S. Patent No. 5,784,584). A second patent from the prior case (U.S. Patent No. 6,598,148) expires in seven months (many years before the other patents-in-suit), while the third patent (U.S. Patent No. 5,809,336) is currently in reexamination before the Patent Office where all claims presently stand rejected.
