Storage rivals QLogic and Emulex on Monday announced they have settled patent infringement lawsuits. Exact terms of the settlement were not disclosed by the companies, which sell components forsystems. However, Emulex said the settlement includes a licensing agreement "under which QLogic is required to pay royalties to Emulex associated with the future sales of certain products and the validity of the three Emulex U.S. patents is acknowledged."
In February 2003, QLogic was sued for patent infringement by Vixel, a company that was acquired by Emulex last November. In December, QLogic sued Emulex for patent infringement. Both suits were settled.
