How many of you knew this?...
Every single patent Musk came up with for his Tesla operation...HE OPEN SOURCED THE PATENTS......
OPEN SOURCE...
........In that, HE DOES NOT OWN THEM. They are PUBLIC.
THIS is the guy that just bought Twitter.
You know what? If he says he's gonna open source Twitter, I am leaning towards believing him.
This is not patent related. It is copyright related.
Copyright normally extends some 25 years beyond the death of an author/creator.
It is likely that Disney trademarked the characters, which is a way of establishing intellectual property rights in this case. Trademarks do not expire automatically, unlike copyright or patents.
As far as I know....
