not be liable to production or inspection in any legal Sect. 9. proceeding, other than an appeal to the law officer under this Act, unless the Court or officer having power to order discovery in such legal proceeding shall certify that such production or inspection is desirable in the interests of justice, and ought to be allowed.
The examiner is to report
Report of (1.) Whether the specification has been prepared in examiner the prescribed manner. As to this see note to sect. 5, on complete sub-sect. (4).
(2.) Whether the invention described in the complete specification is substantially the same as that described in the provisional specification. This provision will prove a most useful one to patentees. Any substantial variation between the two specifications will invalidate the patent (see note to sect. 5). The favourable report of the examiner is not made conclusive as to the absence of any material variation, and whilst the probability of a patent being upset by the allegation of material variation is greatly diminished, it still remains open to defendants to take such an objection.
The report of the examiner is not to be published. It Not to be may be used on appeal to the law officer, but it is not published. liable to production or inspection unless by order of the Court or officer having power to order discovery in such legal proceedings. In proceedings before the Queen's Bench Division of the High Court, see as to the person to whom to apply for such certificate, R. S. C. 1883, Ord. XXXI.
The practice on appeals to the law officer is the same Appeal to as on appeals from the decision of the comptroller requiring amendment of an application (see note to sect. 7).
When there is an appeal pending against a refusal to Time for accept a complete specification the law officer has power to acceptance. direct when the patent shall be sealed (s. 12, sub-s. (3)).
The fact of an application becoming void by its nonacceptance within twelve months does not make it public, and the same principles that apply to applications deemed to be abandoned under sect. 8 apply to applications deemed void under this section. In short, an application refused, abandoned, or void, does not become public and therefore will not affect a subsequent application for a similar invention, except in so far as sub-sect. (5) and (6) of sect. 7 apply.
10. On the acceptance of the complete specification the comptroller shall advertise the acceptAdvertise ance (a); and the application and specification or ment on specifications with the drawings (if any) shall be of complete open to public inspection (B).
Where a complete specification is lodged in the first instance and accepted, it will be open to inspection as soon as it is advertised (Patents Rules, 26).
The Patent Office is open every week day from 10 to when open. 4, except on Christmas Day, Good Friday, Her Majesty's Birthday, and Bank Holidays (see Patents Rules, 7).
11. (1.) Any person may at any time within two to grant of months from the date of the advertisement of the patent. acceptance of a complete specification give notice (7) at the patent office of opposition to the grant of the patent, on the ground of the applicant having obtained the invention from him, or from a person of whom he is the representative, or on the ground that the invention has been patented in this country on an application of prior date, or on the ground of an examiner having reported to the comptroller that the specification appears to him to comprise the same invention as is comprised in a specification bearing the same or a similar title and accompanying a previous application, but on no other ground.
(2.) Where such notice is given the comptroller shall give notice of the opposition to the applicant, and shall, on the expiration of those two months, after hearing (8) the applicant and the person so giving notice, if desirous of being heard, decide on the case, but subject to appeal to the law officer (€).

The Patent Law Amendment Act of 1852 permitted Grounds of opposition. persons having an interest in opposing the grant of letters patent" to oppose the grant after the advertisement of the application, but it did not, like this section, enumerate the grounds of objection that might be taken. 1. That the applicant obtained the invention from the 1. Invenopponent or the person of whom he is the legal tion obrepresentative.
whom he is

2. Invention already patented on prior application.

may take the objection even where he himself
2. That the invention has been patented in this
3. That the examiner has reported to the comptroller
This provision still further secures the first applicant. The previous part of the section prevents a subsequent applicant who may have obtained a patent objecting to a grant to a prior applicant; this proviso enables a prior applicant, if he so chooses, to prevent a grant to a subsequent applicant. Where both applications are made on the same day, the principle of In re Deering's Patent will probably be followed, and a patent granted to both. In this case neither patentee can maintain an action for in
fringement against the other (In re Deering's Patent, Sect. 11. L. R. 13 Ch. D. 393).
It will be observed that opposition to the acceptance of the complete specification is restricted to these three grounds. An application can no longer be objected to on the ground of want of utility or prior public user. The Crown might refuse to grant a patent on either of these grounds, inasmuch as the alleged invention would not be " any manner of new manufacture" within the meaning of sect. 46; but the Act contains no provision for taking either of these objections before the comp
troller or law officer.
1. Any person may take the second ground of opposi- Persons tion, viz., that the invention has already been who may patented on an application of prior date.
2. Any person may also (as far as this section goes)
The person opposing sends to the Patent Office within Practice on two months of the date of the advertisement of the opposition. acceptance of the complete specification, a notice of oppo- Notice. sition in Form T (see Patents Forms), stamped with a 10s. stamp, stating on which of the grounds mentioned. in sect. 11 he intends to oppose. If a ground of opposition be that the invention has been patented in this country on an application of prior date, the title, number, and date of such prior patent must be specified, otherwise opposition on that ground will not be allowed. The notice is also to contain an address for service in the United Kingdom, and be accompanied by an unstamped copy, which the comptroller will send to the applicant.
Within fourteen days after the expiration of two months Evidenc from the advertisement of the acceptance of the complete specification, the opponent is to leave at the Patent Office affidavits in support of his opposition, and send a list of the same to the applicant. The applicant may obtain copies of such affidavits from the Patent Office or the
