AMD sues Realtek and TCL in the US for violating ATI patents

The largest litigations that have taken place so far between companies are usually sealed with non-aggression pacts or payment of minor royalties, where the party that is going to lose is the one that logically gives in first. Between companies within the United States there are not usually too many problems in these battles, but with the Asian ones… Flour from another cost, and now it is AMD that has to deal with it.

AMD, ATI vs Realtek and TCL, what are the problems?

According to AMD through its subsidiary ATI, which it bought a few years ago, the two companies that sell products in the US have violated no less than 5 patents, for which they have been brought to the attention of the USITC through the corresponding complaint.


The problem does not extend, for the moment, outside that country and therein lies part of the little that AMD can get, because being the first a company of Taiwan and the second a company Chinathe legal is not going to cross its borders unless it is a flagrant case.

What AMD says is that both Realtek and TCL have violated a series of patents that have to do with texture decompression techniquesa patent that has to do with graphics rendering architecture using Unified Shaders and also a multi-threaded graphics processing system.

Synchronization and dispatch of asynchronous tasks

AMD patents through ATI have to their credit the ability to synchronize data and events, while on the other hand it allows the processing unit (some part dedicated to the GPU apparently) to assign and send asynchronous tasks with information relevant to it.

The patents speak of thread wavefronts and other technicalities, but what is not specified, at least for now, is where both Realtek and TCL have breached these patents, there is no specification available that details it.

TCL Holding

What is reported is that both companies have violated the section 337 of the Tariff Law of 1930! At the same time, these violations are not reported either, because the process is recent, but already has a deadline imposed by the Chief Administrative Law Judge of the USITC, and the investigation must end within the first 45 days.

Bearing in mind that we now know, but that the demand occurred on May 5, 2022, we are just 15 days away from declaring a resolution, which could take much longer between the parties presenting their arguments and tricks to try to take the sack into the water. The amount requested by AMD has not been specified either, but an exclusion and cessation order is requested for the sale of the affected products, which are not offered either. Where will this demand end? amd against Realtek Y TCL?
