But the definition of a "Trademark" is...
http://www.uspto.gov/trademarks/basics/trade_defin.jsp
Trademark, copyright or patent?
What is a trademark or service mark?
"A trademark is a word, phrase, symbol or design, or a combination of words, phrases, symbols or designs, that identifies and distinguishes the source of the goods of one party from those of others.
A service mark is the same as a trademark, except that it identifies and distinguishes the source of a service rather than a product. Throughout this booklet, the terms "trademark" and "mark" refer to both trademarks and service marks.
Do Trademarks, Copyrights and Patents protect the same things?
No. Trademarks, copyrights and patents all differ. A copyright protects an original artistic or literary work; a patent protects an invention. For copyright information, go to
http://www.copyright.gov . For patent information, go to
http://www.uspto.gov/main/patents.htm ."
So while I can see the words "Talon Hole" can be trademarked, can a hole in a knife guard be a trademark?.. What size hole? what location? What if the hole is oval? How about if it is counter sunk? etc.
So are the words "Talon Hole" the real trademark and they just lead people to believe all holes in knife guards is the trademark? It is hard to believe a hole in a knife guard is actually "Trademarked". If it actually is then there should be a clear cut definition of what that trademark consists of such as size, style and actual location.
I tried to find the trademark Busse Talon Hole but had no luck
