A German judge has dismissed Samsung's patent claims on slide-to-unlock features used in many smartphones, in the latest twist in the contentious patent battle between Apple and Samsung.
The Mannheim Regional Court dismissed charges from Samsung that Apple's iOS platform was infringing on patents it held on touchscreen gestures.
The ruling comes as the latest blow to Samsung in its patent war with Apple.
The company has previously lost intellectual property cases related to its Android handset and tablet devices which threatened to cut off sales and force the company to after its products.
Samsung has said that it will continue to battle Apple in the courts.
Earlier, Apple received a favourable decision from the court allowing it to continue to offer its devices while it appeals a decision in its patent case against Motorola Mobility.
Florian Mueller, a patent law expert who has been monitoring the Android and iOS proceedings in Germany, said that Apple's legal team racked up a "phenomenal week" in court.
Mueller noted that the wins are adding up to help Apple maintain a design advantage with its iOS products.
"Each such decision forces those Android companies to drop or hobble certain features, or precludes them from certain improvements they'd otherwise like to make," Mueller said in a post to the FOSS Patents blog.
"None of the patents asserted so far are 'killer patents', but they cover features that people like."
