So you're filing a patent based on other's open source tech?

I'm sorry, we don't use anyone else open source code (we started building web-based game streaming back in 2017)

We do release a lot of our own though: https://github.com/RainwayApp

I mean if it's built in the browser it's likely using WebRTC under the hood. Might not be the same techniques they described in their article but all the negotiation and transport is built on open source then. Likely also using MS Desktop Duplication API and Media Foundation.

Is a Chrome App (discontinued) which relies on native code whereas Rainway is HTML5 and requires no plugins and works in all spec compliant browsers. We

Was their post edited since you posted this? I'm not seeing any of what you are describing.

It was, they said they were filing a provisional patent
