Uniloc Luxembourg S.à r.l. et al.

I'll research this company before writing the profile.

Uniloc Luxembourg S.à r.l. (formerly Uniloc Luxembourg S.A.) is a Luxembourg-domiciled patent-holding entity within the Uniloc group, with its registered principal place of business at 14, rue Edward Steichen, L-2540 Luxembourg. The Uniloc business was founded in Australia in 1992 by inventor Ric Richardson and developed software product-activation and "try-and-buy" licensing technology. It is a subsidiary of Uniloc Corporation Pty. Limited (Australia), which is not publicly traded; affiliated US operations include Uniloc USA, Inc. (Plano, Texas). Uniloc is generally described in patent-industry sources as a small, low-fixed-cost licensing operation (historically reported at roughly seven employees), with litigation outsourced and analytics handled via its "Centurion" platform. Specific revenue or headcount figures are not reliably disclosed.

Operations. Uniloc is characterized by Unified Patents, RPX, and Stanford's NPE database as a non-practicing entity (patent assertion entity). It no longer develops or sells products; its activity consists of acquiring and licensing patents. Early portfolios were homegrown (product activation, telephony, messaging); later assertions drew on patents acquired from HP/3Com, Philips, IBM, ETRI, and Pendrell, among others. Per RPX, a large share of the portfolio was assigned to Fortress Investment Group-affiliated Uniloc 2017 LLC; Fortress (a SoftBank subsidiary) provided litigation financing to Uniloc from December 2014.

Litigation posture. The single tracked matter is Samsung Electronics America, Inc. v. Uniloc Luxembourg S.à r.l. et al. (Patent Trial and Appeal Board, filed 2017-07-20), an inter partes review in which Uniloc appears as patent owner/defendant. That fits the group's broader pattern: defendants sued by Uniloc routinely petition the PTAB to invalidate the asserted patents. Outside this database, Uniloc is overwhelmingly a plaintiff — RPX reported 130+ infringement suits since 2017 — with filings concentrated in the Eastern District of Texas before TC Heartland shifted venue strategies.

Context. Apple and Intel named Uniloc USA/Luxembourg and Uniloc 2017 as co-defendants in their 2019 antitrust suit against Fortress in the Northern District of California, alleging aggregation and financing of PAE litigation. The asserted patents here concern messaging and communications technologies.
