Inspired by Isaac Asimov’s Three Laws of Robotics, Google wrote a ‘Robot Constitution’ to make sure its new AI droids won’t kill us::AutoRT, a data gathering AI system for robots, has safety prompts inspired by Isaac Asimov’s Three Laws of Robotics that it applies while deciding what task to attempt.
Well, a trademark wouldn't have that consequence, I think at most it could just prevent someone else calling a similar system a "constitution".
Now a patent would be different. If they somehow registered one preventing anyone to use similar safety measures, yeah, that'd be evil. If they can have it enforced, of course.
