Industrial and Commercial Property (Protection) Act, 1927

Opposition to grant of patent.

24.—(1) Any person may at any time within two months from the date of the advertisement of the acceptance of a complete specification give notice at the Office of opposition to the grant of the patent on any of the following grounds:—

(a) that the applicant obtained the invention from the opponent, or from a person of whom he is the legal representative; or

(b) that the invention was published in any complete specification, or in any provisional specification followed by a complete specification, deposited in the Patent Office in London pursuant to an application made in that Office within a period commencing fifty years before the date of the application for the patent the grant of which is being opposed and ending on the date of the commencement of this Part of this Act; or

(c) that the invention was before the date of the application published in any complete specification, or in any provisional specification followed by a complete specification, deposited in the Office pursuant to an application made under this Act or has been made available to the public by publication before the date of the application in any document (other than any such specification as is mentioned in this clause or any British specification published before the commencement of this Part of this Act) published in Saorstát Eireann or published prior to the establishment of Saorstát Eireann in the late United Kingdom; or

(d) that the invention has been claimed in any complete specification for a patent in Saorstát Eireann which though not published at the date of the application for the patent the grant of which is opposed was deposited pursuant to an application for a patent which is or will be of prior date to such patent; or

(e) that the nature of the invention or the manner in which it is to be performed is not sufficiently or fairly described and ascertained in the complete specification; or

(f) that the complete specification describes or claims an invention other than that described in the provisional specification, and that such other invention forms the subject of an application made by the opponent in the interval between the leaving of the provisional specification and the leaving of the complete specification; or

(g) that in the case of an application for a patent made under the provisions of sub-section (1) or sub-section (2) of section 12 (which relates to applications for patents in certain cases) of this Act, the invention claimed or described in the complete specification is not the same invention as the invention which was the subject of the application to the Minister for Economic Affairs of the late Provisional Government of Ireland or the Minister for Industry and Commerce of Saorstát Eireann or was the subject of the protection in the British dominion or foreign state (as the case may be); or

(h) that in the case of an application under the provisions of this Act relating to foreign and British dominion patents the specification describes or claims an invention other than that for which protection has been applied for in the foreign state or British dominion and that such other invention forms the subject of an application made by the opponent in the interval between the leaving of the application in the foreign state or British dominion and the leaving of the application in Saorstát Eireann;

but on no other ground.

(2) Where such notice is given the controller shall give notice of the opposition to the applicant, and shall, on the expiration of those two months, after hearing the applicant and the opponent, if desirous of being heard, decide the case.

(3) The decision of the controller shall be subject to appeal to the law officer, who shall, if required, hear the applicant and the opponent, if the opponent is, in his opinion, a person entitled to be heard in opposition to the grant of the patent, and shall decide the case; and the law officer may, if he thinks fit, obtain the assistance of an expert, who shall be paid such remuneration as the law officer with the consent of the Minister for Finance may determine.
