Modulus Systems, LLC

Modulus Systems LLC is a patent-assertion entity with no known business operations, products, or services. Public records do not indicate a headquarters location, year of foundation, employee count, or revenue. The absence of a corporate website or any public-facing commercial activity, combined with its legal activity, suggests it is a non-practicing entity (NPE) formed to hold and assert patents.

The company's sole activity is patent litigation. It does not appear to develop or sell any products or services. Its patent portfolio appears to relate to technologies implemented by a wide range of operating companies, which it has then sued for infringement.

Modulus Systems LLC is an aggressive patent plaintiff. As the provided case list shows, it has filed at least six patent infringement lawsuits as a plaintiff and has no record of being a defendant. All six of these recent cases were filed on the same day, April 22, 2026, in the plaintiff-friendly Eastern District of Texas. This pattern of behavior—acting exclusively as a plaintiff in patent cases, with no operational business—is characteristic of an NPE, or "patent troll."

On April 22, 2026, Modulus Systems launched a litigation campaign, filing suits against a diverse set of companies including Smart & Green, Loytec Electronics GMBH, Dusun Electron Ltd, Sengled Co Ltd, Tridonic GMBH & Co KG, and Coobuy Ltd in the Eastern District of Texas. The defendants in its various campaigns are often targeted for their use of common technologies. For example, previous litigation by Modulus Systems has targeted companies such as Zebra Technologies and Silicon Laboratories.
