The insurance carrier ultimately agreed to cover the claim and to pay the majority of Pacific Trust’s fees and costs related to the lawsuit.

A team led by Mr. Steinberg filed two IPRs on the Mad Dogg’s patents and after a trial hearing convinced the PTAB that Mad Dogg’s patents are invalid.
  • RetailMeNot, Inc. v. Honey Science LLC – Mr. Steinberg represented Honey Science in a patent infringement lawsuit brought in the US District Court for the District of Delaware.

RetailMeNot moved to stay Honey’s patent based on the filed petitions, and the district court agreed, pending the outcome of the institution decisions. Honey filed POPRs in all three proceedings, and in its detailed decisions denying institution of the two PGRs and the IPR, the PTAB provided 50 page substantive determinations finding the Honey patent claims subject matter eligible under the USPTO 101 Guidelines and non-obvious against the asserted prior art.
