23 cases as defendant.
Intellectual Ventures II LLC is an entity associated with Intellectual Ventures (IV), a privately held invention capital and intellectual property licensing company headquartered in Bellevue, Washington, United States. Founded in 2000 by former Microsoft executives Nathan Myhrvold and Edward Jung, alongside Peter Detkin and Gregory Gorder, the broader Intellectual Ventures organization describes itself as a global invention and investment business. Historically, Intellectual Ventures has managed over $5 billion and possessed one of the world's largest intellectual property portfolios, with more than 40,000 IP assets in active monetization programs.
Intellectual Ventures' operations center on the development, acquisition, and monetization of intellectual property. They acquire patents from individual inventors, universities, and companies, and also engage in internal invention through their IV Lab facility, which conducts advanced research across diverse scientific and engineering fields. The company's primary method of generating revenue is through licensing its extensive patent portfolio and, when necessary, through patent litigation. While they have launched spinout companies like TerraPower and Kymeta, the entity Intellectual Ventures II LLC does not appear to operate products or services directly.
Based on its litigation history, Intellectual Ventures II LLC functions as a Non-Practicing Entity (NPE) or Patent Assertion Entity (PAE). The company has initiated all four of its tracked cases as a plaintiff and has no record as a defendant, indicating a strategy focused on asserting patent rights rather than defending against infringement claims. Its litigation efforts are concentrated in plaintiff-friendly venues, with all tracked cases filed in the Texas Northern, Western, and Eastern District Courts, with the Eastern District of Texas being particularly known for patent assertion.
Notable recent cases include "Intellectual Ventures II LLC et al. v. Southwest Airlines Co." (filed 2026-03-10), "Intellectual Ventures I LLC et al. v. Deere & Co." (filed 2026-02-23), and "Intellectual Ventures I LLC et al. v. American Airlines, Inc." (filed 2024-10-25). The involvement of "Intellectual Ventures I LLC" as a co-plaintiff in several of these cases suggests that Intellectual Ventures II LLC is part of a broader, coordinated patent assertion strategy by the Intellectual Ventures organization, which has historically been backed by major technology companies such as Microsoft, Intel, and Apple.
