PCT Receiving Office Guidelines
Chapter VI: Article 14 Check and Other Formal Requirements
Abstract
147. The receiving Office checks whether the application contains an abstract as provided for in Article 14(1)(a)(iv) but not whether the abstract complies with Rule 8 (in particular, it is not the receiving Office's responsibility to check whether the abstract contains more than 150 words in English or when translated into English). If the receiving Office invites (Form PCT/RO/106) the applicant to furnish a missing abstract, it notifies the International Bureau and also the International Searching Authority accordingly (Rule 38.1 and paragraph 153).
