Kinda. It's basically a love child between server hosting and streaming services with focus on gaming.
You can connect your Steam account, for example, and then run games on their hardware which is streamed to you by browser. So you have control which games to run into but have to bring your own.
Payment options include more powerful hardware but even the basic one was great when I used it. So I could play a modern game with raytracing on my old potato. Your machine just needs to be able to easily stream stuff, so run a modern browser without sweating.
On the offside, it's naturally always online and I had latency problems when many players were online which was common on weekends and what got me to upgrade my setup eventually.
Software patents usually are shitty like that. And weirdly "state or the art" doesn't seem to apply to them. Their only purpose is trolling your competition and the consumer is left with fewer and poorer choices and higher prices due to royalty costs.
One of the most infamous examples is Microsoft filing a patent for the mouse double click in 2002, getting it granted in 2004 while the thing was actually developed before the 80s (and not by Microsoft, of course).
I question the usefulness for society of patents in general but software patents especially should be abolished.
