A Tokyo court has ruled that Samsung infringed on Apple's patent covering a "bounce-back" feature used on the latter's smartphones and tablets.
Reuters reported Friday that Apple had alleged Samsung copied its "bounce-back" function, in which icons on smartphones and tablets quiver back when users scroll to the end of an electronic document.
Samsung has already changed its interface on recent models to show a blue line at the end of documents, the report noted.
The court's decision comes after the U.S. Patent and Trademark Office (USPTO) in April said Apple's patent for the "bounce-back" feature was invalid, allowing older Samsung models with a similar feature to remain on sale.
This is not the first time the global smartphone manufacturers have tussled in Japanese courts. In another lawsuit in August 2012, the Tokyo District Court rejected Apple's claim Samsung stole its technology which enabled the synchronizing of a smartphone's music data with that on a computer. In January this year, Samsung asked the court to dismiss Apple's appeal and stay the favorable ruling toward Samsung.
In March this year, the Tokyo District Court ruled Samsung had no rights over data transmission technology used in some of Apple's iPhones, in response to an injunction filed by the South Korean giant to prevent the manufacture and sale of some Apple smartphones.
