This is silly

[Weltall]

So what is it... just a glorified laser-pointer?

It's several hundred times more powerful than the laser pointers you used in high school to piss off kids across the cafeteria. If used improperly, you can cause serious and permanent damage to yourself or someone else.

All that aside, Lucas will not win this lawsuit unless he can conclusively prove two things:

1: That the design of this device matches a specific design to which he holds a copyright. He does not own proactive rights to all possible variations of lightsaber handle designs.

2: That it was designed with the specific intent to be marketed as if it were affiliated with the Star Wars franchise.

Neither of these will happen, and furthermore, Lucas could only copyright the name 'lightsaber' and any specific visual designs related to it. He cannot copyright a fictional concept, any more than Paramount could copyright the concept of a starship or its warp drive. Lightsaber-like objects appear in many works of fiction entirely unrelated to George Lucas properties, two examples being Mega Man and Silent Hill 3.

This seems like Lucas either followed some spotty legal advice, or he intends to use his superior resources to force a settlement. Either way, it's horse shit.
