I think it would actually be foolish to try. It's a Japanese word in wide use. It would be akin to trying to claim ownership of the word kung fu of taiji or karate. I could see them trying to put some limits on use of the name Ed Parker, but not Kenpo, and I think the attempt would be ludicrous on its face and would not be seen as a credible threat.As I said, they might be able to deter people just by the cost of dealing with the litgation. There's no way I can see that they'd maange to win in court.
This is so far after the fact, there is just no grounds for it. They should have made thes claims decades ago, before millions of people were using it unrestricted. It's difficult to unring that bell.
