Crossroads Systems filed suit against Oracle asserting three patents related to network storage devices that offer virtual local storage (6,425,035; 7,051,147; 7,934,041). Crossroads has filed numerous patent suits dating back to 2000. RPX reviewed the patents in an open market opportunity in April 2012. Crossroads is an operating company that appears to have had financial difficulties over the last few years. Most of the entity’s recent press releases relate either to financial troubles or to its licensing efforts. 10/7, Western District of Texas, 1:13cv00895
