McAndrews, Held & Malloy Secures Victory for Client TQ Delta


Key U.S. PTAB Win Denies Six Petitions for Inter Partes Review

McAndrews, Held & Malloy, a leading intellectual property law firm, is pleased to announce that it successfully defended its client TQ Delta against six petitions by 2Wire for inter partes review on patents related to multicarrier communications systems.

In six separate decisions dated May 29, the Patent Trial and Appeal Board (PTAB) found that petitioner 2Wire did not demonstrate a reasonable likelihood that any challenged claims of the six patents was unpatentable based on the asserted grounds. Therefore, the judges did not institute an inter partes review on any of the asserted grounds as to any of the challenged claims.  The six proceedings are IPR2015-00239, IPR2015-00240, IPR2015-00241, IPR2015-00242, IPR2015-00243, and IPR2015-00247.

“We strongly believed that 2Wire’s arguments failed to prove that our valuable inventions were obvious, and we are happy that the Patent Office agreed,” said Abha Divine, Managing Director of TQ Delta. “These decisions further demonstrate the high quality of our patented inventions, which we believe represent important, foundational IP for the communications industry.”

TQ Delta is represented by McAndrews attorneys Peter J. McAndrews, Thomas J. Wimbiscus, Scott P. McBride, Christopher M. Scharff and Rajendra A. Chiplunkar. Last year, McAndrews, Held & Malloy was recognized by Managing IP magazine, in association with Docket Navigator, in the article, “The surprising rise of the PTAB” as a top firm for patent owners seeking representation in IPR proceedings at the PTAB.

“TQ Delta is very pleased that the PTAB vindicated its position and refused to institute inter partes review on any of the six patents challenged by 2Wire,” said Peter McAndrews, TQ Delta’s lead counsel. “This is an important decision for patent owners.  It puts teeth in the requirement that petitioners articulate a sufficient reason to combine disparate prior art references. If followed by other panels, it may dampen the high rate of IPR institution by the PTAB.”

McAndrews has one of the most active dockets of AIA trial proceedings of any law firm in the United States.  The firm has represented clients in more than 100 inter partes review and covered business method patent review proceedings on behalf of both petitioners and patent owners.
