Apple sued over 'fast-charge' feature on Apple iPhone 6s98
Somaltus says that Apple's fast-charge feature infringes on U.S. patent 7,657,386, called "Integrated Battery Service System." From Apple, the company seeks unspecified damages or continuing royalties. Apple isn't the only smartphone company that Somaltus is taking to court over the alleged infringement of this patent. Other companies (in alphabetical order) like Asus, Lenovo, Samsung, Sony, and Toshiba have also been sued over the same technology.
The plaintiff appears to have a game plan in mind; put pressure on the defendant companies and force them to settle. This worked already with Ford and Nissan. Both car manufacturers decided to settle after being sued for allegedly infringing on the same patent. For Somaltus, a settlement means scoring a big pay day without having to put up the money required to take the case to court.
