(10) The foregoing provisions of this section do not apply when and so long as any action for infringement or proceeding for revocation of a patent is pending.

26. In any action for infringement of a patent and in a proceeding for revocation of a patent the Court or a Judge in Chambers may at any time order that the patentee shall, subject to such terms as to costs and otherwise, as the Court or a Judge in Chambers may impose, be at liberty to apply at the Patent Office for leave to amend his specification by way of disclaimer, and may direct that in the meantime the trial or hearing of the action shall be postponed.

27. Where an amendment by way of disclaimer, correction, or explanation has been allowed under this Proclamation, no damages shall be given in any action in respect of the use of the invention before the disclaimer, correction, or explanation, unless the patentee establishes to the satisfaction of the Court that his original claim was framed in good faith and with reasonable skill and knowledge.

28. Every amendment of a specification shall be advertised in manner prescribed by the Commissioner.

29. If, on the petition of an interested party, it is proved to the satisfaction of the Governor that, in consequence of the refusal of a patentee to grant licences to use his invention on reasonable terms

(c) anyone is prevented from making use of or deriving the full benefit from an invention of which he is possessed

the Governor may order the patentee to grant licences for the use of the said invention, under such conditions as to the amount of royalties, security for payment, or otherwise, as the Governor, regard being had to the nature of the invention and the circumstances of the case, may deem just, and any such order may be made an order of the Court.

30. There shall be paid to the Commissioner in respect of the several instruments described in Schedule "H" to this Proclamation the fees in that Schedule mentioned, and there shall likewise be paid in respect of any other matters under this Proclamation such fees as may from time to time be prescribed by the Commissioner with the consent of the Governor.

(3) The Court shall, on such reference being made by the Governor, appoint a day for hearing such application, and, at least two months before the day appointed for such hearing, the applicant shall publish, in manner prescribed by the Court, a notice of the contents of his application as nearly as possible in the form prescribed in Schedule "G."

(6) The Court, in its report, shall take into consideration the nature and the merits of the invention and the value thereof to the public, the profit derived therefrom by the patentee, and the further circumstances of the case. The report shall further state whether,

in the opinion of the Court, it is advisable to grant an extension, and, if so, for how long and under what conditions or restrictions. The Court shall further direct by whom the costs of the case between the parties shall be borne, and an order as to the costs made or granted by the Court may be legally enforced.

32. The Governor shall have the right, after considering the application for an extension and the report of the said Court thereon, to grant an extension of the term of the patent under such conditions and restrictions, and for such a length of time (in no case longer than fourteen years), as he may think desirable. The extension of the term of the patent shall date from the day of the expiration of the original term thereof.

33. (1) There shall be kept at the Patent Office a register called "The Register of Patents," wherein shall be entered the dates of applications for patents, the names and addresses of grantees of patents, notifications of assignments and transfers, and of transmission of patents, of licences under patents, and of amendments, exten

sions, and revocations of patents, and such other matters affecting the validity or proprietorship of patents as may from time to time be prescribed, provided that there shall not be entered in the register, or be receivable by the Commissioner, any notice of any trust express, implied or constructive.

35. Any person who makes, or causes to be made, a false entry in a register kept in terms of this Proclamation, or produces or tenders, or causes to be produced or tendered in evidence, any such false entry or false copy or extract, knowing the same to be false, shall be punished with imprisonment, with or without hard labour, for a period not exceeding five years.

36. (1) The Court may, on application by any person who complains of an unjustifiable entry or unjustifiable omission of an entry, or of any other particulars in such register, make such order for the striking out, insertion, or amendment of such entry as the Court shall deem necessary. The Court may also dismiss the application,

and make an order as to costs in either case.
