You may have noticed recently that WWE has been buying up trademarks left, right and center. The trademarks tend to be related to WCW and other older promotions such as WCCW.
The Wrestling Observer Newsletter suggests that the reason the company is filing these trademarks is because MLW beat them and trademarked War Games, which they were not happy about. This now allows MLW the ability to use that term for wrestling material.
So for those hoping they might be registering trademarks to bring back older events, think again.
