Chapter 14 Industrial Applicability
14.04 For the assessment of industrial applicability, the following steps are applied:
(i) determine what the applicant has claimed; and
(ii) determine whether a person skilled in the art would recognize the claimed invention to have industrial applicability.
14.05 In most cases, industrial applicability will be self-evident and no more explicit description on this point will be required.
Rules 43bis, 66.2(a)(ii), 70.8
14.06 If any product or process is alleged to operate in a manner clearly contrary to well-established physical laws and thus the invention cannot be carried out by a person skilled in the art, the claim does not have industrial applicability and the applicant should be so notified.
