Do I need an attorney to file my trademark application?

An applicant is responsible for observing and complying with all substantive and procedural issues and requirements whether or not represented by an attorney. Applicants are not required to hire an attorney for assistance with trademark filings, although it may be desirable to employ an attorney who is familiar with trademark matters. The names of attorneys who specialize in trademark law may be found in the telephone yellow pages, or by contacting a local bar association. The U.S. Patent and Trademark Office cannot aid in the selection of an attorney.
