Maxell filed another lawsuit accusing Apple’s Wi-Fi assistant and other features of infringing its patents.

Electronics maker Maxell filed a new lawsuit Thursday alleging that products and features such as Apple’s Wi-Fi assistant and password unlock violated five of its patents,media apple Insider reported. The lawsuit, filed in U.S. District Court for the Western District of Texas, comes more than a year after Maxell filed a similar lawsuit alleging that Apple infringed 10 U.S. patents. Maxell’s lawsuit on Thursday brought the total number of patents to 15.

Maxell filed another lawsuit accusing Apple's Wi-Fi assistant and other features of infringing its patents.

The U.S. patents that Maxell referred to in the lawsuit cover a number of technologies, including mobile communications, device unlocking, white balance adjustment settings, wireless video sharing, and facial recognition in photo albums.

For example, the company said that Apple’s “People” album in photos grouped individual photos in violation of U.S. patent number 10,176,848. The patent includes a technology that allows users to register a photo of a specific person and “categorize and associate records” of a future image of the same person.

Another patent referred to in the complaint, no. 7,203,517, describes a way to curb communication instability, allowing the system to choose between different communication systems based on several factors. Maxell said Apple’s Wi-Fi assistant feature violated the patent.

In addition, the Japanese company claims that Apple’s secure unlock system, photo-editing tools in Camera, and AirPlay and Bluetooth sharing have all violated three separate patents. In addition to specific software features, a range of different Apple devices have also been identified as infringing products. They include everything from the iPhone 7 to the 16-inch MacBook Pro.

In each patent infringement charge, Maxell argued that Apple had always known the patents existed and could not “reasonably” believe they were invalid. Apple continues its tort activities, despite knowledge and subjective belief, and it is objectively likely that its actions constitute infringement,” the lawsuit reads.

Maxell is seeking a jury trial, as well as damages and a preliminary and permanent injunction against software and hardware.

Apple’s first lawsuit with Maxell is still ongoing. Recently, a U.S. district judge granted special measures in the case to allow Maxell to review Apple’s source code in connection with patent infringement claims.
