- Vringo (VRNG +4.8%) says it has been mailed a notice by the USPTO stating "it will issue a certificate confirming that all of the claims of U.S. Patent No. 6,314,420 remain valid and unchanged."
- The '420 patent is one of two being asserted by Vringo in its suit against Google. The USPTO affirmed the validity of the other one (Vringo's '664 patent) last fall.
- The notice follows a non-final rejection by the USPTO of certain claims within the '420 patent back in January.
