Can anyone help a newbie with a few questions?
Can I do a trademark search on my proposed business name as well as file it with the USPTO, or must i hire an attorney or firm to do this?
Is a trademark search required with the state that I intend to do business?
How often do I need to renew my registered trademark to keep it valid?
What is the difference between the TM and R trademark logos?

I expected to recognize a lot more than 8 of the 15 logos. Isn’t recognizability the whole goal?
