The stock has remained stable for the last few days but the activity has been pretty tepid with low volumes. The adverse judgment in the Cisco (CSCO) patent infringement case killed the stock within a matter of days. The news about case filed against Microsoft (MSFT) for infringements by Skype products saved it from crashing further. However, even news on the patent infringement lawsuit against Apple (AAPL) has been bad with Apple trying to contest VirnetX's $368 million claim. The company is pretty much dependent on these lawsuits, and the stock moves wildly with the type of news flow. Investors have to live with this but the recent crash has definitely shaken the faith as the stock halved in two-three days. Such sudden blows indicate the requirement for a more balanced business model with a steady stream of revenues. In fact companies like Marathon Patent Group (MARA) are attempting to achieve that. Marathon acquired several revenue generating patents recently and also acquired CyberFone for getting ownership of its revenue earning portfolio. Earlier, Marathon was majorly in news for the lawsuit filed by its subsidiary Sampo IP LLC against Sony, Dell, Siemens etc. That lawsuit is up for Markman hearing in October and the company has filed another lawsuit in the same court for the same patents against ETrade Financial Corporate Services Inc., Liberty Mutual Group Inc., Aetna Inc., Avon Products Inc., Starbucks Corporation, Yum! Brands Inc., Hewlett-Packard Company, and Alcatel-Lucent USA Inc. Another of its subsidiary, Relay IP has also filed a patent infringement lawsuit against Sprint Nextel, Juniper Networks, Cisco, Bloomberg, D-Link Corporation, Avaya, HP, Huawei Technologies, Hitachi Cable America etc. All this indicates that while companies continue to pursue infringement lawsuits, they are also alive of the need to get a regular cash inflow to make their business less dependent on outcomes of lawsuits. VirnetX may need to increase its efforts on this.
