Hardware manufacturer Lenovo will suspend sales of all PCs, laptops, tablets and smartphones in Germany on Thursday.
The company has not paid for its licenses to use a video codec, H.264,
H.264 is the most widely used video codec in the world and is used to create MPEG-4 video files.
The patent for this codec belongs to Nokia.
The judge ruled at the end of September that Lenovo is indeed infringing Nokia's patent law by not paying for its licenses.
To enforce this decision, Nokia went to court on Tuesday.
The company was proved right there.
Lenovo will therefore immediately stop selling computers in Germany.
The hardware manufacturer is appealing.
In the United States, Brazil and India, the two companies are also in conflict with each other in court.
