Empire Technology Development LLC

Empire Technology Development LLC is a Delaware-based non-practicing entity (NPE) involved in patent monetization. It is an operating subsidiary of Allied Inventors Fund LLC, which was established in 2007 to develop and monetize technologies. Allied Inventors Fund is managed by Allied Inventors Management LLC and has over $600 million in capital commitment from institutional investors. Reports from 2021 indicate Empire Technology is a subsidiary of Allied Inventors Management (AIM), which was founded to monetize patents received from Intellectual Ventures LLC (IV).

As a non-practicing entity, Empire Technology Development does not manufacture products or offer services. Its operations consist of acquiring and asserting patents. The company's large patent portfolio, which at one point included over 1,600 in-force U.S. patents, covers a wide range of technologies, including semiconductors, wireless communications, multicore processors, power management, and medical devices. The company has divested portions of its portfolio to other patent assertion entities, including multiple entities controlled by the high-volume filer IP Edge LLC.

The company's litigation posture is exclusively that of a plaintiff. As shown in the authoritative case data, Empire Technology Development has only appeared as a plaintiff, never as a defendant. This is characteristic of a patent assertion entity whose business model is based on generating revenue through litigation and licensing of its patent portfolio. The company has filed suits in popular patent litigation venues, such as the Western District of Texas and the District of Delaware.

The database tracks a recent case filed on April 17, 2026, Empire Technology Development LLC v. Intel Corp, in the Western District of Texas. This suit alleges that Intel's Xeon CPU mesh architecture infringes on a patent related to routing data. Prior to this, Empire engaged in a series of lawsuits in 2025 against other major technology companies, including AMD, NVIDIA, AT&T, and Texas Instruments. The patents asserted in these cases relate to technologies such as network-on-chip routing, power management based on leakage current, and congestion-aware routing in computer networks.
