Products / services / operations. Digital Realty is an operating company, not an NPE.

Patent-litigation posture. The tracked data show Digital Realty exclusively as a defendant (0 plaintiff cases, 1 defendant case) — the signature of an operating company defending against assertion, not an active two-way litigant. That single suit was filed in the plaintiff-friendly Eastern District of Texas, Marshall Division.

Notable case. Valtrus Innovations Ltd. v. Digital Realty Trust, Inc. et al., No. 2:24-cv-00950 (E.D. Tex., filed Nov. 20, 2024, before Judge Rodney Gilstrap), was a patent-infringement action by Valtrus Innovations Ltd. and Key Patent Innovations Ltd. — Irish entities characterized in coverage as patent-holding/licensing vehicles asserting a portfolio originating with Hewlett Packard Enterprise. The patents asserted against Digital Realty concerned data-center cooling, atmospheric control and energy management (e.g., U.S. 6,854,284; 6,868,682; 7,251,547), with Digital Realty's facilities and its EkkoSoft Critical optimization software named as accused instrumentalities. Plaintiffs filed a notice of voluntary dismissal on January 17, 2025. Valtrus/KPI filed similar cooling-patent suits against other data-center operators, including CyrusOne, NTT, CoreSite and Iron Mountain. No public validity ruling resolved the asserted patents.
