The company's patent litigation history in the provided database consists of a single case where it was the defendant, which is typical for a large operating company. In this role, ADP defends against patent infringement claims. The one tracked case, EXPRESS MOBILE, INC. v. ADP, LLC, was filed in the Delaware District Court in 2017.

The plaintiff in that case, Express Mobile, Inc., is a patent assertion entity that has litigated patents related to web and mobile development technology against numerous other companies. Notably, Express Mobile has won significant verdicts in other cases, including a $170 million jury award against GoDaddy for infringing foundational web-design patents. This context suggests the lawsuit against ADP likely involved similar web-based technology used in its HCM platforms.
