Patents Act 1977

Examination and search U.K.

17 [F1 Search.] U.K.

[F2 (1) The comptroller shall refer an application for a patent to an examiner for a search if, and only if—

(a) the comptroller has referred the application to an examiner for a preliminary examination under section 15A(1) above;

(b) the application has not been withdrawn or treated as withdrawn;

(c) before the end of the prescribed period—

(i) the applicant makes a request to the Patent Office in the prescribed form for a search; and

(ii) the fee prescribed for the search (“the search fee”) is paid;

(d) the application includes—

(i) a description of the invention for which a patent is sought; and

(ii) one or more claims; and

(e) the description and each of the claims comply with the requirements of rules as to language.]

(2) [F3 On a preliminary examination of an application the examiner shall determine whether the application complies with those requirements of this Act and the rules which are designated by the rules as formal requirements for the purposes of this Act and shall report his determination to the comptroller.]

(3) [F3 If it is reported to the comptroller under subsection (2) above that not all the formal requirements are complied with, he shall give the applicant an opportunity to make observations on the report and to amend the application within a specified period (subject to section 15(5) above) so as to comply with those requirements (subject, however, to section 76 below), and if the applicant fails to do so the comptroller may refuse the application. ]

(4) Subject to subsections (5) and (6) below, on a search requested under this section, the examiner shall make such investigation as in his opinion is reasonably practicable and necessary for him to identify the documents which he thinks will be needed to decide, on a substantive examination under section 18 below, whether the invention for which a patent is sought is new and involves an inventive step.

(5) On any such search the examiner shall determine whether or not the search would serve any useful purpose on the application as for the time being constituted and—

(a) if he determines that it would serve such a purpose in relation to the whole or part of the application, he shall proceed to conduct the search so far as it would serve such a purpose and shall report on the results of the search to the comptroller; and

(b) if he determines that the search would not serve such a purpose in relation to the whole or part of the application, he shall report accordingly to the comptroller;

and in either event the applicant shall be informed of the examiner’s report.

(6) If it appears to the examiner, either before or on conducting a search under this section, that an application relates to two or more inventions, but that they are not so linked as to form a single inventive concept, he shall initially only conduct a search in relation to the first invention specified in the claims of the application, but may proceed to conduct a search in relation to another invention so specified if the applicant pays the search fee in respect of the application so far as it relates to that other invention.

(7) After a search has been requested under this section for an application the comptroller may at any time refer the application to an examiner for a supplementary search, and [F4 subsections (4) and (5) above] shall apply in relation to a supplementary search as [F4 they apply] in relation to any other search under this section.

[F5 (8) A reference for a supplementary search in consequence of—

(a) an amendment of the application made by the applicant under section 18(3) or 19(1) below, or

(b) a correction of the application, or of a document filed in connection with the application, under section 117 below,

shall be made only on payment of the prescribed fee, unless the comptroller directs otherwise.]

(a) the fee is paid, or

(3) If the examiner reports that any of those requirements are not complied with, the comptroller shall give the applicant an opportunity within a specified period to make observations on the report and to amend the application so as to comply with those requirements (subject, however, to section 76 below), and if the applicant fails to satisfy the comptroller that those requirements are complied with, or to amend the application so as to comply with them, the comptroller may refuse the application.

(4) If the examiner reports that the application, whether as originally filed or as amended in pursuance of [F9 section 15A] above, this section or section 19 below, complies with those requirements at any time before the end of the prescribed period, the comptroller shall notify the applicant of that fact and, subject to subsection (5) and sections 19 and 22 below and on payment within the prescribed period of any fee prescribed for the grant, grant him a patent.

(5) Where two or more applications for a patent for the same invention having the same priority date are filed by the same applicant or his successor in title, the comptroller may on that ground refuse to grant a patent in pursuance of more than one of the applications.

(2) Anything done under or in relation to the application during the period between termination and reinstatement shall be treated as valid.

(3) If the application has been published under section 16 above before its termination anything done during that period which would have constituted an infringement of the rights conferred by publication of the application if the termination had not occurred shall be treated as an infringement of those rights—

(a) the refusal of the application, or

(b) the application being treated as having been refused or withdrawn.]
