Based on its litigation history, Dusun Electron is an operating company defending against patent assertions. It has been named as a defendant in one patent case and has not been tracked as a plaintiff. This pattern is characteristic of a technology manufacturer being targeted by a patent holder. The suit was filed in the U.S. District Court for the Eastern District of Texas, a jurisdiction frequently chosen by patent plaintiffs.

The single tracked case is Modulus Systems LLC v. Dusun Electron Ltd, filed in April 2026. The plaintiff, Modulus Systems LLC, has filed similar patent infringement lawsuits against other technology companies in the same district.
