Including Alder Lake
Intel lost a patent dispute in Germany. Because of this, sales of some of the company's processors are now prohibited there.
A regional court in Düsseldorf has ruled that Intel has infringed R2 Semiconductor's patent on voltage regulation technology. Throughout the case, Intel argued that a ban would be a disproportionate remedy. As we see, it was the ban that ended the matter.
The injunction, unfortunately for Intel, also applies to very modern CPUs. If the Ice Lake and Tiger Lake models, which also contain the technology discussed, are practically never found in any devices today, then Alder Lake is even more relevant. In addition, the ban also applies to fairly recent server CPUs Xeon Scalable Ice Lake.
Intel itself does not believe that it has infringed any patents. In addition, the company said that R2 Semiconductor's covered patent was invalidated in the United States. In addition, Intel accused R2 Semiconductor of being a patent troll. At the moment, Intel has also filed an application with a German court asking that the R2 patent be invalidated in that country. True, right now Intel is suing the same company in the UK.
