It also doesn't have to be that they are 'bullying' anyone.
They could do this fully expecting to lose, purely to maintain or publicize a posture that they're not to be taken lightly. Legal moves are not so one dimensional that they have to be bullying their target. Just getting the press that they'll go to court with all their might over a word in a title in a completely unrelated game is a message to the industry.
If you have Netflix you may have seen the example of
The Asylum. They make movies like 'The Day The Earth Stopped' and 'Battle of Los Angeles' which blatantly steal money and earn subscriptions from anyone they fool using other companies' success. Fox threatened to sue them, but never actually did... so why would they ever stop? Why would they hesitate to do another Fox movie? Why would a major company hesitate to take a cut (Netflix)?
