(a) particulars of the grounds on which the applicant relies; and

(a) evidence is not admissible to prove a ground of invalidity that has not been disclosed in the particulars in relation to that ground; and
(b) evidence as to apparatus or machinery that exists at the date of lodgment of the particulars is not admissible unless it is proved that the party relying on the evidence:
(i) if the apparatus or machinery is in his or her possession--has offered the opportunity to inspect it; or
(ii) in any other case--has used reasonable endeavours to obtain its inspection;
to, or by, each other party to the hearing of the application.
