I'm interested in registering my trademark. I've found that I can register it through my state (Ohio) and through the US government.
Trademark registration with the US government is FAR better than
state registration. It gives you rights across the whole US for your
trademark (think web sales) but only for the specific class and goods
you register it for. I strongly recommend you use a trademark
attorney but before you even spend a nickel on them follow every link
at Inventor Home Trademark Information Access page (a web site of mine) and
read the material. Then do your own trademark searches to be
reasonably sure you won’t be wasting your money on something that is
almost certain to be rejected (or opposed) and only take your final
one to the trademark attorney (look under patent attorneys or
intellectual property attorneys in your phone book). You may also
want to pay $400 or so for a professional search after you’ve found a
trademark you think is okay because once you’ve filed your
application and paid for it and your attorney costs you can’t get
any of that money back if your application is rejected.
