3946Re: Don't mention "C Crane" or "Twin Coil Ferrite Loop"
- Sep 1, 2007My 2 cents as a layman, IANAL:
The trademark thing could be called fair use, since you are only
identifying the item you reverse engineered. IE, you aren't trying to
pass off your own design as if it were C. Crane's.
And a trademark search on http://www.uspto.gov shows no matches for
either "C. Crane" nor "Twin coil ferrite am antenna". The first is the
guy's name (someone's name is not trademarkable) and the second is
merely descriptive (which is also not trademarkable).
The copyright thing sounds like pure FUD. You didn't redraw the patent
drawing, you reverse engineered the actual item. Copyrights are -very-
specific in nature, so your schematic would have to be an almost exact
copy in placement of lines and components and text to be an infringement.
And so far, reverse engineering an item is still legal.
