Dwight, I tried to follow up on the PRAV patent. The press release had the wrong patent number and the wrong reexam number. The reexam number they provided is actually the patent number, and I could not locate the reexam patent. Without the reexamined patent its tough (impossible) to evaluate whether the actual claims are worth much. FWIW, the original claims required a random code generation. If the reexam claims include that limitation, it would be important to know if standard GPS uses such a code. i don't know. Do you? If you get the right number for the re-exam, I'll take a look at it.
