Wireless Monitoring Systems patent challenged as likely invalid

On October 6, 2017, Unified filed a petition for inter partes review (IPR) against U.S. Patent 9,280,886 owned and asserted by Wireless Monitoring Systems, LLC, an NPE controlled by Bradley D. Liddle (an individual connected to Personal Audio and several other patent assertion entities). The '886 patent, directed to monitoring systems that are especially useful in security management systems, fire systems and building management systems, is at dispute in two district court cases against Charter Communications and MONI Smart Security
