Do I Need a Patent Attorney/Agent to Prepare and File a Patent Application?

Applicants may prepare their patent applications and file them without assistance from a patent attorney. However, given the complexity of patent documents and the legal skills required, it is highly advisable to seek legal assistance from a patent attorney/agent when drafting a patent application. Furthermore, the legislation of a country may require that the applicant whose ordinary residence or principal place of business is outside the country be represented by an attorney or agent admitted (which usually means, resident and practicing) in the country.  Information on the admitted attorneys and agents may be obtained directly from the national IP offices.
