February 24, 2025—Inmar Brand Solutions, Inc. notched a significant win over competitor Quotient Technology Inc. when the Patent Trial and Appeal Board refused to institute an inter partes review of U.S. Patent No. 10,846,729 (“the ‘729 Patent”), one of three patents at issue in Inmar’s patent litigation lawsuit against Quotient.  

The ‘729 Patent claims inventions that describe computer systems for clearing coupons. The claims specify how those systems are configured or how they operate. Inmar is the exclusive licensee of the ‘729 Patent, which was developed by Intelligent Clearing Network, Inc. 

After Inmar sued Quotient for patent infringement in federal district court for the District of Delaware, Quotient filed an inter partes review petition with the PTAB challenging the validity of the ‘729 Patent. Quotient argued that certain claims of the ‘729 Patent were rendered obvious by five prior art publications.  

A panel of three Administrative Patent Judges rejected Quotient’s petition after finding that there was not a reasonable likelihood that Quotient would prevail in establishing that any of the challenged claims of the ‘729 Patent would be unpatentable as obvious.  

A Bunsow De Mory team of partners Denise De Mory, Wayne Helge, James Wilson, and Marc Belloli and associate Brenda Entzminger crafted the winning arguments to defeat Quotient’s petition.

The proceedings on the inter partes review petition are entitled Quotient Technology, Inc. V. Intelligent Clearing Network, Inc., IPR2024-01325. 

The patent infringement action is Inmar Brand Solutions, Inc. v. Quotient Technology Inc., No. 1:23-cv-00994 (D. Del.).
