I can promise you that Fraudhofer has NEVER made an algorithmic innovation which would not have been "discovered" within 5 years. Of the things they have patented which are coherent enough to even qualify as an innovation, they're more likely to have been actually discovered 20 years ago by someone else.

And they're pretty much worst in class, there's no practical way they're better than other algorithm patent extortionists.

By the way, algorithms should not be patentable, and legally aren't patentable, but some presumably corrupt bureaucrats decided they for all practical purposes are patentable anyway.
