PTAB Invalidates Two Crossroads Patents in Cisco, NetApp, Oracle, and Quantum IPRs
- February 3, 2016
In a major setback for publicly traded NPE Crossroads Systems, Inc., the Patent Trial and Appeal Board (PTAB) has invalidated two of the NPE’s patents (6,425,035; 7,051,147) in a series of inter partes reviews (IPRs) brought by Cisco, Oracle, NetApp, and Quantum. Along with Huawei, the petitioners had been targeted by Crossroads in lawsuits filed in late 2013/early 2014 that asserted the challenged patents along with two others (7,934,041; 7,987,311). Those cases were stayed by District Court Judge Sam Sparks in June 2015 pending IPR of all four of the patents-in-suit.
