VirnetX higher after favorable rulings in Apple suit

• In a Markman order, the Eastern Texas district court has rejected an Apple motion for summary judgment seeking to invalidate certain VirnetX (NYSE:VHC +3.6%) patent claims on grounds of indefiniteness.
• It has also "granted in part and denied in part VirnetX's Motion for Partial Summary Judgment on Apple's Invalidity Counterclaims." Apple is precluded from asserting invalidity for VirnetX patent claims covered during the companies' jury trial, but can do so for other claims.
• VirnetX rallied in June after an RPX request (on behalf of Apple) for a USPTO review of several VirnetX patents was denied.
