PTRCs are neither required nor encouraged to conduct patent and trademark searches for their patrons as that activity may be interpreted as rendering a legal judgment or opinion. PTRC representatives are not attorneys and cannot provide legal advice. Please contact a registered attorney or agent for a complete patent and trademark search and for legal advice. For more information about legal assistance and resources, please visit the USPTO website.
