CommScope patent infringement case strengthened

CommScope received a decision from the Patent Trial and Appeal Board (PTAB), which rejected Dali Wireless´ petition challenging the validity of CommScope´s patent relating to digital distributed antenna systems (DAS), the company said.

After reviewing all of Dali´s evidence, testimony and argument, the PTAB agreed with CommScope and denied Dali´s petition to institute an Inter Partes Review (IPR), concluding that Dali failed to establish a reasonable likelihood that Dali would prevail against any challenged claim of the patent.

CommScope is enforcing multiple patents from its digital DAS portfolio against Dali in federal district court in Texas. As to CommScope´s asserted patents, with this decision from the PTAB, the IPR phase of the case is complete, and all of CommScope´s asserted claims remain in the case.
