This is a most excellent place for technology news and articles.
Unless I’m mistaken, and I probably am, the patents on blueray should have expired by now. Software side might be covered under copyright right though. Not sure if software can be copyrighted though tbh.
Software is copyrighted but nothing stops you from coding your own identical version. You just can't re-use any code from the original.
