I can imagine that at that point the company owning the Python trademark would be able to go after other companies offering Python services for trademark infringement, and various other legal threats related to it...

This is a stupid question to ask. Naturally they will not loose their right to use the name.

There's no need to be hostile in your response to a legitimate question; even if the answer seems painfully obvious to yourself and others.

After all, we all learn by asking questions.

Well, the question itself is stupid not because something is obvious in the outcome, but because obviously nobody can predict the future. And using simple words is not hostile, at least using the term "stupid" in my previous comment had no hostility intended.

I excuse for any irritation it might have caused and hopefully I could remove now any of these.
