Andy is strict with these things. Long ago he changed the name of my submission because that word is trandmarked. The same time I had got a few uploads with the same word approved without any problem. Of course I fully trust the reviewers in what they do, but I was just wondered how the appelative noun can be trademarked? (I’m not native English speaker but pretty sure that the word “transformer” existed in English far long before those loud … khm, “blockbusters” were released.)
Another one: AJ sfx contributor uploaded recently a bunch of sound effects titled with obviously trademarked names. Not sure how it’s reglamented by rules but in his case this info (which exact brand of car engine was recorded) is surely highly useful for customers!
Add.: I see your case should be allowed according to point a.?
