Company overview. SpaceTime3D, Inc. is a privately held software and patent-holding company based in New York. It was founded around 1999 by Edward ("Eddie") Bakhash, who served as CEO; early press described it as a small, self-funded team. No current employee count, revenue, or valuation figures are publicly available, and the company has no public ticker or disclosed parent.
Products / operations. SpaceTime3D originally developed "SpaceTime," a Windows 3D web browser first released in public beta on June 4, 2007. The browser displayed web pages and search results (Google, Yahoo, Flickr, eBay) as textured slabs in a simulated 3D space, with a timeline for history and tabbed browsing, and let users toggle between 3D and 2D views. It was showcased at CES 2008 and received mixed press reviews, but the product appears to have been discontinued around 2010. The company's remaining value is its patent portfolio, primarily U.S. Patent Nos. 8,881,048, 9,304,654, and 9,696,868, which cover 3D graphical user interfaces for navigating webpages and applications and switching between 3D and 2D displays. Unified Patents categorizes SpaceTime3D as an "NPE (Small Company)" in PTAB proceedings, though the Stanford NPE Litigation Database lists it as a product company — reflecting its transition from operating company to patent monetizer.
Litigation posture. SpaceTime3D is an active two-way litigant: it filed the three district-court actions in the tracked data (against Samsung in E.D. Tex. in 2019, and against Apple in W.D. Tex.–Waco and LG in E.D. Tex., both in 2022), while six PTAB petitions filed by Apple, Google, LG, and Samsung target its patents. Cases were filed in the plaintiff-friendly Eastern District of Texas and Waco division of the Western District of Texas. Counsel Susman Godfrey has stated the Samsung and LG cases settled favorably.
Notable context. In August 2026, the Federal Circuit issued two nonprecedential rulings: it affirmed PTAB findings that claims 14–18 of the '048 patent and all challenged claims of the '654 and '868 patents were obvious, while upholding claims 1–13 of the '048 patent. The asserted technology concerns iOS app-switcher and Safari tab-view interfaces.
IPR proceeding challenging claims 1-19 of the '654 patent. The Unified Patents portal lists LG Electronics USA Inc. as petitioner, while the IPR2023-00343 Final Written Decision notes that Google LLC's petition in this proceeding was the basis for Google's joinder; the precise caption is uncertain.
IPR filed by LG against the '868 patent, with Google joining. The PTAB issued its final written decision on July 2, 2024.
Apple petitioned for IPR challenging all claims of the '654 patent, and Google LLC joined as a party. The Board issued a Final Written Decision on July 2, 2024, finding claims 1-19 unpatentable as obvious, and the decision was appealed to the Federal Circuit.
IPR instituted on Apple's petition with Google joining, challenging claims 1-20 of the '868 patent. The PTAB found all challenged claims obvious, and the Federal Circuit affirmed.
Samsung petitioned for inter partes review challenging claims 1-19 of the '654 patent. The petition was dismissed prior to institution, and Google Patents labels the status as 'Settlement.'
IPR proceeding against the '868 patent that terminated due to settlement. The petitioner was not confirmed.
