Ingenico Inc. v. IOENGINE, LLC, United States District Court of Delaware
Sunstein obtained a sweeping jury verdict win in a patent infringement lawsuit for Ingenico Inc., a global provider of point of sale payment terminals, software, and services. Sunstein also filed multiple petitions for inter partes review (IPR), successfully invalidating over 150 of the patent claims in IOENGINE’s three asserted patents.

The exhaustive discovery process included tens of thousands of documents, 20-plus depositions (including multiple depositions of third parties in Israel), and significant third-party discovery. Notably, Sunstein challenged the methodology by which IOENGINE’s damages expert calculated reasonable royalty damages, prompting the court to exclude the expert’s testimony. After four days of testimony, the jury found that all claims were either not infringed or were invalid.
