Nazomi Communications has filed a lawsuit against ARM Holdings, saying ARM's acceleration technology and products for Java platforms are infringing on a Nazomi patent. Both companies make microchips that incorporate part of a Java Virtual Machine into their hardware. Nazomi said it is seeking a permanent injunction against ARM as well as unspecified damages. The suit was filed in the Federal District Court for Northern California. In a statement, ARM called the suit "frivolous" and said it would "vigorously defend itself."
