A Tokyo court has ruled Samsung hasn't infringed on an Apple patent, in the latest development in the legal battle between the two technology titans.
The Tokyo District Court ruled on Friday that the technology used in the South Korean company's smartphones and tablet to synchronise with computers did not infringe on an Apple patent.
This is a separate case from a US lawsuit between the two companies.
Last week, a jury in California ruled some of Samsung Electronics Co's smartphones violated Apple patents. The jury awarded Apple Inc $US1 billion ($A975.47 million) in damages.
