Real Networks, Inc.

Real Networks, Inc. (RealNetworks) — Founded in 1994 by Rob Glaser as Progressive Networks, renamed RealNetworks, Inc. in December 1996, headquartered at 1501 First Avenue South, Seattle, Washington. It was publicly traded on Nasdaq under ticker RNWK until December 21, 2022, when founder/CEO Glaser's affiliate Greater Heights LLC acquired it in a take-private merger; the surviving entity is RealNetworks LLC, 100% owned by Greater Heights (itself 100% owned by Glaser via GH Sliver, Inc.), per the company's SEC SC 13E3/A and merger filings. Headcount in the final public reporting period was roughly 280 employees; revenue was in the tens of millions (about $55–58M on a trailing-twelve-month basis before the going-private transaction). Pre-merger shareholder litigation over that transaction was filed in 2024.

Products and operations. RealNetworks is an operating software company, best known for streaming-media technology: RealAudio and RealVideo formats, the RealPlayer media player, the Helix media-delivery platform, RealDownloader, and the Unifi personal cloud service. Its later portfolio shifted toward artificial-intelligence products — SAFR (computer-vision/facial-recognition platform), KONTXT (NLP-based message classification and anti-fraud for carriers), and a mobile free-to-play games business. It previously owned/operated Rhapsody and Napster (Napster divested in 2020) and marketed the RealDVD product, which was enjoined under the DMCA.

Patent-litigation posture. RealNetworks is an operating company, not a patent assertion entity. In the tracked data it appears only as a defendant (0 plaintiff cases, 1 defendant case), consistent with a product company being sued on third-party patents. The sole tracked matter is Friskit, Inc. v. Real Networks, Inc., at the U.S. Court of Appeals for the Federal Circuit — the appeal from the Northern District of California, not an Eastern District of Texas venue.

Notable case context. Friskit sued in 2003 in N.D. Cal., alleging RealNetworks' media player and content services infringed patents on searching and playing back online media (reported damages demand of $70M). The district court granted summary judgment of invalidity in 2007 under KSR v. Teleflex; the Federal Circuit affirmed on January 12, 2009, invalidating all asserted claims as obvious. The technology focus — networked media search and playback — mirrors RealNetworks' core streaming business.
