I looked into it a couple years back for a knife I designed. Wanted to trademark the name and patent the design. Turned out both were more than I wanted to spend.
You can do it yourself without hiring a bottom feeder (lawyer). Don't recall where I found the info. Goggle it and you will come up with do it yourself info.
First thing is a T.M. search , then applications and fees , and then the actual T.M.
Be aware that not all T.M.'s will come up in the search , if you apply and the T.M. is already registered ,you don't get a refund on the fees.
