Cisco Systems, Inc. v.WSOU Investments LLC d/b/a Brazos Licensing and Development
Cisco Systems successfully petitioned the PTAB to institute an IPR against WSOU Investments regarding network protection claims (8982691). The Board found sufficient evidence of obviousness under 35 U.S.C. § 103, specifically finding that prior art references inherently disclose key claim limitations.

The PTAB denied institution of IPR for Cambridge Mobile Telematics against Sfara, citing Petitioner's failure to provide a proper claim construction under 37 C.F.R. § 42.104(b)(3).
