Any legal guesses as to why those 2 companies are treated differently with regards to the very generic words : "open", "text", "AI" ?
EDIT add another example is Open Systems that has a office in Switzerland. https://www.open-systems.com/
The trademark registrations search results: https://www.tmdn.org/tmview/#/tmview/results?page=1&pageSize...
We can assume the OpenAI lawyers brought up these and other similar examples and the court rejected the past examples as a valid argument.
