This isn't exactly a Kali issue, but I was speaking with yet another JKD instructor last night who is shying away from using the JKD name because of both the arguments between original/concepts/nucleus/etc. groups, and the fears that the Lee family is trying to enforce a trademark on "Jeet Kune Do" that would force those using the name to pay them a licensing fee. (Is this true, or just a rumor? I note that Dan Inosanto has started calling it 'Jeet Kuen' (sic) instead, for example.) People traded on the name for years, but now there seems to be something of a backlash against using it!
