Final Rules Limiting Scope of Patent Agent Representation.
Per this Federal Register notice promulgated on August 14th, Rule § 11.5 detailing what constitutes acceptable practice before the USPTO has been revised to read as follows:
§ 11.5 Register of attorneys and agents in patent matters; practice before the Office.
(a) A register of attorneys and agents is kept in the Office on which are entered the names of all individuals recognized as entitled to represent applicants having prospective or immediate business before the Office in the preparation and prosecution of patent applications. Registration in the Office under the provisions of this part shall entitle the individuals so registered to practice before the Office only in patent matters.
(b) Practice before the Office. Practice before the Office includes, but is not limited to, law-related service that comprehends any matter connected with the presentation to the Office or any of its officers or employees relating to a client’s rights, privileges, duties, or responsibilities under the laws or regulations administered by the Office for the grant of a patent or registration of a trademark, or for enrollment or disciplinary matters. Such presentations include preparing necessary documents in contemplation of filing the documents with the Office, corresponding and communicating with the Office, and representing a client through documents or at interviews, hearings, and meetings, as well as communicating with and advising a client concerning matters pending or contemplated to be presented before the Office. Nothing in this section proscribes a practitioner from employing or retaining non-practitioner assistants under the supervision of the practitioner to assist the practitioner in matters pending or contemplated to be presented before the Office.
(1) Practice before the Office in patent matters. Practice before the Office in patent matters includes, but is not limited to, preparing and prosecuting any patent application, consulting with or giving advice to a client in contemplation of filing a patent application or other document with the Office, drafting the specification or claims of a patent application; drafting an amendment or reply to a communication from the Office that may require written argument to establish the patentability of a claimed invention; drafting a reply to a communication from the Office regarding a patent application; and drafting a communication for a public use, interference, reexamination proceeding, petition, appeal to or any other proceeding before the Board of Patent Appeals and Interferences, or other proceeding. Registration to practice before the Office in patent cases sanctions the performance of those services which are reasonably necessary and incident to the preparation and prosecution of patent applications or other proceeding before the Office involving a patent application or patent in which the practitioner is authorized to participate. The services include:
(i) Considering the advisability of relying upon alternative forms of protection which may be available under state law, and
(ii) Drafting an assignment or causing an assignment to be executed for the patent owner in contemplation of filing or prosecution of a patent application for the patent owner, where the practitioner represents the patent owner after a patent issues in a proceeding before the Office, and when drafting the assignment the practitioner does no more than replicate the terms of a previously existing oral or written obligation of assignment from one person or party to another person or party.
(2) Practice before the Office in trademark matters. Practice before the Office in trademark matters includes, but is not limited to, consulting with or giving advice to a client in contemplation of filing a trademark application or other document with the Office; preparing and prosecuting an application for trademark registration; preparing an amendment which may require written argument to establish the registrability of the mark; and conducting an opposition, cancellation, or concurrent use proceeding; or conducting an appeal to the Trademark Trial and Appeal Board.
As originally stated in the U.S. Supreme Court opinion of Sperry v. Florida (1963), patent agents and out-of-state patent attorneys may perform tasks which are “incident to the preparation and prosecution of patent applications before the Patent Office.” § 11.5(b)(1) at first reiterates this standard by providing that “registration to practice before the Office in patent cases sanctions the performance of those services which are reasonably necessary and incident to the preparation and prosecution of patent applications or other proceedings before the Office involving a patent application or patent in which the practitioner is authorized to participate.”
Under the revised Rule § 11.5, the preparation of a patent assignment has been clarified as acceptable, under the following (and typical) circumstances:
The services are identified as including considering the advisability of relying upon alternative forms of protection which may be available under statute law, and drafting an assignment or causing an assignment to be executed for the patent owner in contemplation of filing or prosecution of a patent application for the patent owner, or the practitioner represents the patent owner after a patent issues in a proceeding before the Office, and in drafting the assignment the practitioner does no more than replicate the terms of a previously existing oral or written obligation of assignment from one person or party to another person or party.
However, the new Rule § 11.5 cuts much deeper, providing that validity opinions are only authorized under very limited circumstances, and that infringement opinions are under no circumstances included within the scope of an agent’s practice before the USPTO.
The suggestion to define practice before the Office as rendering opinions on validity and infringement for clients has not been adopted. Whether a validity opinion involves practice before the Office depends on the circumstances in which the opinion is sought and furnished. For example, an opinion of the validity of another party’s patent when the client is contemplating litigation and not seeking reexamination of the other party’s patent could not be reasonably necessary and incident to the preparation and prosecution of patent applications or other proceedings before the Office involving a patent application or patent. In such situations, the opinion may constitute unauthorized practice of law.
In no circumstance would practice before the Office include the rendering of opinions on infringement. Under the law, the Office has no authority to resolve infringement cases. Thus, registration to practice before the Office in patent cases does not include authority to render infringement opinions.
