Samsung has added Apple’s latest handset to a US patent lawsuit claiming the iPhone 5 infringes eight of its technologies.
The disputed innovations include a way to synchronise photos, music and video files across several devices, and a method to capture and send video over the internet.
Samsung had already filed claims against earlier iPhones and iPads.
It coincides with calls from a judge for “major reforms” to US patent law.
Judge Richard Posner, who previously oversaw a legal dispute involving Apple and Google’s Motorola unit, said that protection available to software patents was “excessive”.
Samsung’s legal move is the latest in a long running battle with Apple.
The US firm has claimed that the Galaxy device maker copied the look and iOS system software found on its tablets and handsets.
Although several of Apple’s claims have been rejected, it recently scored a major victory when a California-based jury ruled Samsung should pay it over $1bn (£620m) in damages.
Samsung has had its own courtroom successes, including a ruling in August that Apple had infringed two of its wireless communication patents in South Korea. It resulted in an order for the iPhone maker to pay 40m won ($35,000; £22,000) in damages.
