Since mid-October, a plaintiff calling itself “NetMomentum LLC” has fired off five lawsuits, one against each of ASUSTek, Panasonic, Samsung, VTech Holdings, and Yealink Network Technology. In its complaints, all filed in the Eastern District of Texas, the plaintiff characterizes itself as a Delaware entity located at a New York, New York address. However, an assignment record recently made public by the USPTO has raised questions about the accuracy of those representations, perhaps calling into question the standing of this plaintiff, as characterized, to sue.
