terested, be ordered to be granted by the Board of Trade in respect of a patented invention, where, by reason of the default of the patentee in granting licences on reasonable terms, one or other of the following circumstances occur. These are—(1) that the patent is not being worked in the United Kingdom, (2) that the reasonable requirements of the public with respect to the invention cannot be supplied, or (3) that any person is prevented from working or using to the best advantage an invention of which he is possessed (t). The order may be for the grant of licences on such terms as to the amount of royalties, security for payment or otherwise, as the Board having regard to the nature of the invention, and the circumstances of the case, may deem just, and any such order may be enforced by mandamus (t). These provisions do not apply to patents granted before the commencement of the

act, or on applications then pending (u). Secretary for Inventions of any improvement in instruments or munitions of War may

The registers under the old practice are to be deemed parts of Registration the same book as the Register of Patents under the new act (>). practice. The practice of registration, however, is considerably altered. Formerly (a), entry was made of documents themselves. Now, entries are to be made of the names and addresses of grantees of patents, and notifications [only] of assignments and of transmissions of patents, of licences under patents, and of amendments, extensions and revocations of patents, and such other matters affecting the validity or proprietorship of patents as may from time to time be prescribed (6). The register is primâ facie evidence of any matter by the act directed or authorized to be inserted (6). No notice of any trust, expressed, implied or constructive, can be entered on the register or receivable by the comptroller (c). Further, the

person for the time being registered as proprietor of any patent shall, subject to any rights appearing from the register to be vested in any other person, have power absolutely to assign, grant licences as to, or otherwise deal with the same, and to give effectual receipts for any consideration for such assignment, licence or dealing, but equities may be enforced as in respect of any other personal property (d).

therefore, as such cannot be registered. Licences, or agreements under seal having the effect of licences, can, perhaps, be registered, although they were executed before the patent was sealed, as the limited patent rights obtained before the sealing will form part of those granted by the patent itself, and the prescribed form of a patent (s) does not restrict the date at which the consent, licence or agreement may be given by the patentee.

As to agreements between co-applicants or co-patentees stating the terms on which they, working separately, shall respectively use the patent rights, it is presumed that they are fit subjects for registration, on the ground that they amount to licences between the parties (g). It is presumed that no instrument executed before

9 the actual date of the sealing of a patent, and purporting to be an assignment thereof, or of some share or interest therein, will amount to an assignment of a legal estate or interest, so as to admit of registration. This seems to result from the circumstance that the purported assignment would be inconsistent with the terms of the patent, and that no legal grant can be made of property of which the grantor has neither an actual nor a potential ownership at the time of grant (1). It does not seem that any other documents executed before a patent is sealed can be registered, except the licences and agreements above mentioned, and the legal assurances

of any such instruments (i). Rectification By sect. 90 of the new act (j), provisions are made for the rectiof the register fication of the register and the expungement or varying of any by expunge

(9) It has been stated at the Patent Office that after the grant has been duly recorded documents executed before the sealing of the patent, and even during the period of provisional protection, which give any legal rights or estate in a patent, may be notified on the register. Mr. Lawson intimates (p. 30) that it was, and presumably would be, the practice not to register documents affecting provisional specifications only. This opinion does not, perhaps, apply to licences and agreements above mentioned, which are intended to extend beyond the period of provisional protection.

fit. No case appears to be reported in connection with this section. As these provisions are practically of the same nature as those under the Act of 1852 (k) in the above respect, it may be well to take notice of some of the legal decisions under the old law relating to the latter provisions. In Re Green's Patent (?), a patentee in 1853 assigned the patent to persons who did not at first register the assignment. A new assignment of the patent was made in 1855 to the father of the patentee for valuable consideration, who thereupon registered his assignment before the first assignees registered theirs. On the application of the latter, the first entry was ordered to be expunged (m). In Re Morey's Patent the facts were nearly similar, except that the first assignment was only of a moiety of the patent, and it was held that a subsequent assignee from the patentee had constructive notice, on account of the recital in his deed of assignment, of the prior interest, although it was therein described merely as a licence. The entry of the second assignment was not ordered to be expunged, but the court directed that a statement should be entered on the register that the licence referred to was actually the assignment in question, and refused to direct a statement to be entered to the effect that the second assignee had had notice of the first assignment, as the notice was only constructive. Where a deed is good and bona fide, it would seem that no entry could be made on the register qualifying its effect, or giving it a construction (n). According to this rule, it was held

a that the entry of a deed of assignment of his half share by one co-patentee, who thereby also purported to release his assignee from all claims by himself and the other co-patentee, should, on the application of the latter, be expunged, as the deed could not be altered (o).

(m) In the report of that case it does not appear that the second assignee had any notice, express or constructive, of the prior assignment; but, in Re Morey's Patent, 25 Beav. 583, the decision in Re Green's Patent was treated as having been based on the fact of fraud, to which the second assignee was privy.
