Registrar at any time after the applicant has complied with the requirements imposed
upon him by this Act:
Provided that the applicant may give notice to the Registrar requesting him to
postpone acceptance until such date, not being later than eighteen months from the
date of lodging of the complete specification, as may be specified in the notice and
the Registrar may postpone acceptance accordingly.
(2) Subject to subsection (5), on the acceptance of a complete specification the
Registrar shall give notice to the applicant who shall, within the prescribed period or
within such further period as the Registrar may allow, advertise in the Journal the fact
that the specification has been accepted and, unless the acceptance of the
specification is so advertised, the application shall lapse.
(3) Upon advertisement in terms of subsection (2) the application form, the
specification and the other documents essential to obtain acceptance which were
lodged in pursuance thereof shall be open to public inspection unless the acceptance
of the complete specification has been cancelled in terms of subsection (5) before
such advertisement.
(4) After the date of the publication in terms of subsection (2) of notice of acceptance
of a complete specification and until the sealing of a patent in respect thereof, the

been sealed on the date of the publication of the notice unless the acceptance of the
complete specification has been cancelled in terms of subsection (5) before that date.
(5) If so requested before the advertisement in the Journal in terms of subsection (2)
of the acceptance of a specification, the Registrar may at any time prior to the
publication of such advertisement cancel in the prescribed manner the acceptance of
that complete specification and on such cancellation he shall—
(a)
make a note thereof in the Register; and
(b)
if the advertisement of the acceptance is subsequently published in the
Journal, cause notice of the cancellation of the acceptance of the specification to be
published in the Journal.
(6) The cancellation of the acceptance of a complete specification in terms of
subsection (5) shall not preclude the Registrar from re-accepting that complete
specification at a later date if at the time the applicant requested the cancellation he
also gave notice to the Registrar such as is referred to in the proviso to subsection (1).
