Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Internet security and software company VirnetX (AMEX: VHC) popped as much as 11.5% this morning before giving back nearly all of its gains after a U.S. District Court issued a Markman Order regarding an ongoing patent infringement claim.

So what: The order, which rules on patent claim language, often serves as a great indicator for which way the court will eventually rule. According to VirnetX, which has filed patent claims against Cisco Systems (Nasdaq: CSCO), Apple (Nasdaq: AAPL), NEC, and Aastra, for violating two of its VPN-related patents, the initial comments look favorable to it winning.

Now what: VirnetX isn't a stranger to suing larger corporations over patent rights, as it successfully sued Microsoft (Nasdaq: MSFT) in 2007 after alleging that Microsoft Office Communicator and Microsoft Office Meeting violated two of its patents. VirnetX later settled with Microsoft for $200 million. It's not unreasonable to think VirnetX isn't in line to win another case, but I also wouldn't bet the farm on a patent infringement case. At a forward P/E of 82, there are far better values to be had in the technology space than VirnetX.
