Realtime Data LLC d/b/a IXO is a privately held New York limited liability company headquartered in Armonk, New York, with no public ticker and no disclosed parent. It has described itself in litigation filings as holding 47 U.S. patents, and RPX Corporation's transaction with the company covered "nearly 60 US patents and foreign equivalents." No employee count or revenue figures are publicly reported; it operates as a small licensing entity. Its founder-associated inventor is Paul Fallon.
Operations: Realtime Data is a non-practicing entity / patent assertion vehicle. It develops and sells no products or services. Its portfolio covers content-dependent and content-independent data compression, data-feed acceleration, and accelerated data storage and retrieval — technology it asserts reads on compression and deduplication in backup software, cloud storage, and networking products. A related entity, Realtime Adaptive Streaming LLC, has been characterized in defendant SEC filings as "an entity that seeks to license an acquired patent portfolio without itself practicing any of the claims recited therein."
Litigation posture: Predominantly a plaintiff. The tracked data show 6 plaintiff cases versus 2 "defendant" cases, and both of those two are USPTO Patent Trial and Appeal Board proceedings brought against it (by SAP America and Oracle America) — i.e., defensive IPRs, not affirmative suits. Filings cluster heavily in the plaintiff-friendly Eastern District of Texas, Tyler Division, with later actions in Delaware, Colorado, Massachusetts, and California. RPX has stated Realtime sued more than 100 companies over a decade.
Notable cases: Realtime Data v. DISH Network/Sling TV (D. Colo., refiled 2017); suits against SAP America, Oracle America, Teradata, and BMC Software; and PTAB challenges by Oracle (IPR2016-0037) and SAP. In 2023 the Federal Circuit affirmed §101 patent-ineligibility rulings against several asserted patents (Delaware/Quantum line), and the Supreme Court denied certiorari in January 2024 (No. 23-498). RPX subsequently completed a syndicated licensing transaction resolving disputes involving its participants.
