CommScope received a significant 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).

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.

“This is a clear win for CommScope,” said Matt Melester, senior vice president, Distributed Coverage and Capacity Solutions, CommScope. “To ensure our continuing ability to invest and drive innovation, it’s important that we vigorously protect our valuable patent assets. This decision by the PTAB serves to further validate the innovations made by CommScope in digital DAS technology.” 

The Board’s decision can be found in Inter Partes Review Case No. IPR2017-01324. CommScope’s patent infringement action against Dali Wireless is CommScope Technologies LLC v. Dali Wireless, Inc., No. 3:16-cv-477-B pending before the United States District Court for the Northern District of Texas and involves U.S. Patent No. 7,848,747.
