Dot Hill Files Suit Against Crossroads Systems for Patent Infringement

Press Releases  |

LONGMONT, Colo., June 30, 2015 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp. (HILL) , a recognized leader in software and hardware solutions for information storage, filed suit yesterday against Crossroads Systems, Inc. for patent infringement in United States District Court in Denver. The asserted patent, U.S. Patent No. 7,277,995, covers access control technology for data storage systems and is asserted against Crossroads' StrongBox storage solution.

Dot Hill innovation has resulted in numerous patent awards on its technologies, and the patent asserted against Crossroads is part of Dot Hill's 100-plus patent portfolio. Dot Hill's intellectual property, demonstrated by its extensive patent portfolio, stands on three pillars of innovation which, when combined, provide a complete platform for addressing customers' storage needs. Dot Hill's pillars of innovation include storage firmware, hardware platforms, and systems, which combine to create advanced SAN storage solutions.

"Dot Hill recognizes that building world class products takes a serious investment in engineering and intellectual property—and we are committed to defending our intellectual property rights against infringement," said Dana Kammersgard, Dot Hill President and CEO. "We are proud to count many creative technologists in our engineering teams who have developed a range of patented inventions covering numerous aspects of our product offerings, from the core firmware, to the storage controllers, to the data management software that makes our solutions work. These inventions developed by our engineers deserve protection from unauthorized use."

In September 2013, Crossroads filed suit against Dot Hill in Austin, Texas, claiming infringement of U.S. Patent 6,425,035 and breach of contract. Crossroads also sued Oracle, Cisco Systems, Huawei Technologies, Tandberg Data, NetApp, and Quantum for patent infringement. Dot Hill recently won a stay of the Texas litigation pending the completion of two inter partes review proceedings before the United States Patent Office, which challenge the validity of the '035 patent. Final written decisions on the validity of Crossroads' '035 patent will issue from the United States Patent Office in early 2016.
