This chapter describes the ethics demanded by the Patent and Trademark Office. These rules pertain to both registered patent agents and attorneys.

There may be a question or two from this chapter on the patent bar exam, although the exams seem to be moving away from this material. This is unfortunate as the questions pertaining to ethics have traditionally been the easiest to answer. Many of them are simple and can be answered using common sense. Nonetheless, we still recommend that you take the time review the key points included here.

The Director of Enrollment and Discipline may send out letters to regulate a practitioner for the purpose of ascertaining whether they wish to remain on the register and if no reply is received, without further warning, the name may be removed from the register:
the names of individuals so removed will be published in the Official Gazette
no notice is needed for these postings
registration only entitles one to practice before USPTO in patent cases
a practitioner is proscribed from neglecting an entrusted legal matter
the following are NOT part of PTO ethics:
replying to an Office action by stating honestly and truthfully in the remarks accompanying an amendment that you have personally used the device and found it to be very efficient and better than prior art
the PTO does not want your opinion on the subject matter (!)
filing an amendment with copied claims from another issued patent and withholding from Office the information identifying the patent the claims were copied from
failing to disclose controlling legal authority adverse to a client's interest when arguing the patentability of the claims in a patent application

§ 10.15 Refusal to recognize a practitioner.

(1) All statements made therein of the party's own knowledge are true, all statements made therein on information and belief are believed to be true, and all statements made therein are made with the knowledge that whoever, in any matter within the jurisdiction of the Patent and Trademark Office, knowingly and willfully falsifies, conceals, or covers up by any trick, scheme, or device a material fact, or makes any false, fictitious or fraudulent statements or representations, or makes or uses any false writing or document knowing the same to contain any false, fictitious or fraudulent statement or entry, shall be subject to the penalties set forth under 18 U.S.C. 1001, and that violations of this paragraph may jeopardize the validity of the application or document, or the validity or enforceability of any patent, trademark registration, or certificate resulting therefrom; and
(2) To the best of the party's knowledge, information and belief, formed after an inquiry reasonable under the circumstances, that
(i) The paper is not being presented for any improper purpose, such as to harass someone or to cause unnecessary delay or needless increase in the cost of
prosecution before the Office;
(ii) The claims and other legal contentions therein are warranted by existing law or by a nonfrivolous argument for the extension, modification, or reversal of existing law or the establishment of new law;
(iii) The allegations and other factual contentions have evidentiary support or, if specifically so identified, are likely to have evidentiary support after a reasonable opportunity for further investigation or discovery; and
(iv) The denials of factual contentions are warranted on the evidence, or if
specifically so identified, are reasonably based on a lack of information or belief.
(c) Violations of paragraph (b)(1) of this section by a practitioner or nonpractitioner may jeopardize the validity of the application or document, or the validity or enforceability of any patent, trademark registration, or certificate resulting therefrom. Violations of any of paragraphs (b)(2)(i) through (iv) of this section are, after notice and reasonable opportunity to respond, subject to such sanctions as deemed appropriate by the Commissioner, or the Commissioner's designee, which may include, but are not limited to, any combination of
(1) Holding certain facts to have been established;
(2) Returning papers;
(3) Precluding a party from filing a paper, or presenting or contesting an issue;
(4) Imposing a monetary sanction;
(5) Requiring a terminal disclaimer for the period of the delay; or
(6) Terminating the proceedings in the Patent and Trademark Office.
(d) Any practitioner violating the provisions of this section may also be subject to disciplinary action. See § 10.23(c)(15).

§ 10.33 Direct contact with prospective clients.
A practitioner may not solicit professional employment from a prospective client with whom the practitioner has no family or prior professional relationship, by mail, inperson, or otherwise, when a significant motive for the practitioner's doing so is the practitioner's pecuniary gain under circumstances evidencing undue influence, intimidation, or overreaching. The term "solicit" includes contact in person, by telephone or telegraph, by letter or other writing, or by other communication directed to a specific recipient, but does not include letters addressed or advertising circulars distributed generally to persons not specifically known to need legal services of the kind provided by the practitioner in a particular matter, but who are so situated that they might in general find such services useful.

§ 10.36 Fees for legal services.
(a) A practitioner shall not enter into an agreement for, charge, or collect an illegal or clearly excessive fee.
(b) A fee is clearly excessive when, after a review of the facts, a practitioner of ordinary prudence would be left with a definite and firm conviction that the fee is in excess of a reasonable fee. Factors to be considered as guides in determining the reasonableness of a fee include the following:
(1) The time and labor required, the novelty and difficulty of the questions involved, and the skill requisite to perform the legal service properly.
(2) The likelihood, if apparent to the client, that the acceptance of the particular employment will preclude other employment by the practitioner.
(3) The fee customarily charged for similar legal services.
(4) The amount involved and the results obtained.

(6) The nature and length of the professional relationship with the client.

A practitioner who withdraws from employment shall refund promptly any part of a fee paid in advance that has not been earned.
(b) Mandatory withdrawal. A practitioner representing a client before the Office shall withdraw from employment if:
(1) The practitioner knows or it is obvious that the client is bringing a legal action, commencing a proceeding before the Office, conducting a defense, or asserting a position in litigation or any proceeding pending before the Office, or is otherwise having steps taken for the client, merely for the purpose of harassing or maliciously injuring any person;

(1) If the testimony will relate solely to an uncontested matter.
(2) If the testimony will relate solely to a matter of formality and there is no reason to believe that substantial evidence will be offered in opposition to the testimony.
