On February 25, 2021, Unified Patents added a new PATROLL contest, with a $5,000 cash prize, seeking prior art on at least claim 1 of U.S. Patent 7,409,715. The patent is owned by the most prolific NPE assertor in 2020, WSOU Investments, LLC d/b/a/ Brazos Licensing and Development.

The ‘715 patent generally relates to an impersonation attack detection system for a wireless node of a wireless communication network. Specifically, Unified seeks art on the method that operatively connects the wireless node with an intrusion detection module, provides the intrusion detection module with a copy of the original data frames transmitted by the wireless node over a wireless interface, and then compares information in the copy with information in incoming data frames at the intrusion detection module. During prosecution, the patent examiner allowed the claims of the ’715 patent over U.S. Patent 6,745,333 based on these features. The ‘715 patent is currently being asserted against Arista Networks in the Western District of Texas.

The contest will expire on May 15, 2021. Please visit PATROLL for more information and to submit an entry for this contest.
