2.   After section four a of the Principal Act, the following section is inserted:—

Extension of Act to New Guinea.

“4b.—(1.)  On and after a date to be fixed by proclamation, this Act shall apply to the Territory of New Guinea as if that Territory were part of the Commonwealth, and no application for a patent under any patent law (other than this Act) applying to that Territory shall be receivable except pursuant to some right previously acquired.

(2.)    For the purposes of the application of this Act to the Territory of New Guinea, any reference in this Act to the Commonwealth or to Australia shall be deemed to include a reference to the Territory of New Guinea.

(b) any application for a patent lodged or made in New Guinea prior to the said date, or any patent granted on any application so lodged or made.”.

3.—(1.)  Section sixty-four of the Principal Act is amended by omitting from sub-section (1.) thereof the word “fourteen” and inserting in its stead the word “sixteen”.

(2.)    Any patent the original term of which had not expired at the date of the commencement of this section shall have effect as if the term mentioned in the patent was sixteen years instead of fourteen years, subject to the condition that any licence existing at that date which has been granted for the term of the patent shall be treated as having been granted for the term as so extended if the licensee so desires.

(3.)    Where any party to a contract with the patentee or any other person, entered into before the nineteenth day of November One thousand nine hundred and seventeen, is subjected to loss or liability by reason of the extension of the term of any patent under the provisions of this section, the Court shall have power to determine in what manner and by which parties such loss or liability shall be borne.

Provided that this sub-section shall not apply if the patentee is a subject of such foreign State as aforesaid, or is a company the business of which is managed or controlled by such subjects or is carried on wholly or mainly for the benefit or on behalf of such subjects, notwithstanding that the company is registered within His Majesty’s Dominions.
