This Center appoints as adjudicators, one attorney-at-law and one patent attorney from this Center's list of adjudicator candidates. In addition, when any of the adjudicators request so, this Center may increase the number of adjudicators up to three, by appointing one additional adjudicator from the above list. See the list and background information of adjudicator candidates here.

In order to verify that a adjudicator has no interest with the parties to the Advisory Opinion, the adjudicator shall be subject to an information disclosure obligation, such as, an obligation to submit a "written commitment with respect to the interests" to this Center and to the parties.
The applicant may, upon written application, and the respondent may, upon written acceptance, designate a person whom they consider to be an interested third party in connection with the case, with a written designation of particular interested persons.

When there are circumstances which give rise to justifiable doubts as to a adjudicator's impartiality or independence, the parties to the Advisory Opinion may request a challenge to such adjudicator. When there are grounds for such request, this Center shall allow the challenge and appoint another adjudicator.
