APPLE INSIDER
Electronics maker Maxell on Thursday filed a new lawsuit accusing Apple of infringing on at five of its patents with products and features like Wi-Fi Assist and passcodes.

The complaint, lodged in the U.S. District Court for the Western District of Texas, comes more than a year after Maxell filed a similar lawsuit that claimed Apple was violating 10 U.S. patents. Maxell’s lawsuit on Thursday brings the total number of patents to 15.
