To be honest, I don't see how Spyderco can have a trademark on a hole. It is, afterall, a hole. No one invented a hole. Spyderco just found a novel ideal of placing a hole in a certain part of the blade.
Can you really trademark a hole? Maybe they're trademarking the location of the hole?
They didn't patent the hole, they patented the ability to open a knife via a depression in the blade (like a hole, or oval, or triangle). That patent has expired, but the round hole is still a Spyderco trademark, every knife (with the exception of one) has it.
