That is what I was looking for. I need to research the "Trade-dress or Design Violation" issue a little more. Thanks.
This seems to be similar to the issue raised by ferrariz, but I could see the crownguard or Triplock mechanisms themselves being trademarked. I was speaking in more general terms of just the body and design, but again, ferrariz point seems to cover that as well. For example, take a Black Magic, pretty distinctive without looking at the crown or dials. So under the trade dress or design issue, it would appear that I would still have a problem if I used the same body, screws, bezel, etc. with no reference or markings related to HBB. That would seem harsh, but I guess it is the design that makes it so popular to some.
