sends this excerpt from Ars: U.S. Circuit Judge William Bryson, sitting "by designation" in the Eastern District of Texas, has found in a summary judgment ruling (PDF) that the patent, owned by TQP Development, is not infringed by the two defendants remaining in the case, Intuit Corp. and Hertz Corp. In a separate ruling (PDF), Bryson rejected Intuit's arguments that the patent was invalid.
Not a complete victory (a clearly bogus patent is still not invalidated), but it's a start.
