What Will the USPTO do for You? (And What Won't They Do?)
YES YOU CAN!
Call them at (571) 272-9250 or (800) 786-9199 to request a status check of your Federal trademark application. Be sure to have your serial number handy.
You can also call either number to get general information about the trademark process.
NO YOU CANNOT!
USPTO employees are not able to:
"* conduct trademark searches for the public;
* comment on the validity of registered marks;
* answer questions as to whether a particular mark or type of mark is eligible for registration;
* offer legal advice or opinions about common law trademark rights, state registrations, or trademark infringement claims; or
* aid in the selection of a private trademark attorney or search firm."
