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: For the third consecutive trading session, shares of VirnetX (AMEX: VHC) jumped more than 10% on hopes that someone would make a big bid for its 4G patent portfolio.

So what: The story is beginning to get stale. Unless, that is, you're an investor in VirnetX shares. Institutions seem to keep revising their estimated value of VirnetX's portfolio, and then buying once convinced that one of the would-be 4G contenders -- from AT&T (NYSE: T) to Apple (Nasdaq: AAPL), among others -- will be forced to bid big or face being left behind.

Now what: Speculators can be forgiven for piling in, especially given the riches paid to the likes of Nortel and Motorola Mobility. But there may also be a better way to profit from patent-palooza, as Fools Eric Bleeker and Jeremy Phillips discuss in this video. What's your take? Would you buy at these levels?
