Letters of Registration.

Section 20. For any invention patented elsewhere no Letters Patent can bo issued; but Letters of Registration will be granted on compliance with Regulations Nos. 13 and 14, and on payment of £10. Such Letters of Registration will be kept in the Patent Office, and will have the same effect in the colony as Letters Patent, but will continue only as long as the original Letters Patent. (A certified copy will be supplied on payment of nine shillings.)
