5. In case such letters patent shall be obtained, the said A. B. shall, if required by the said C. D. and E. F., or either of them, during weeks from the date of the assignment of the said letters patent, personally teach, instruct, inspect, and assist all the workmen, servants, and others who shall be named for that purpose by the said C.

(9) The statutes 5 & 6 Will. 4, c. 83; 6 & 7 Vict. c. 38; and 7 Extension of & 8 Vict. c. 69, empower the Crown, on the advice of the Judicial patents. Committee of the Privy Council, to extend the term of patent privileges for not more than fourteen years beyond the first fourteen ; but an extension will be granted only upon the petitioner establishing first the merit of the invention, secondly, that the parties interested have done all in their power to bring it into public use and turn it to advantage, and thirdly, that from circumstances beyond their control they have been unable to obtain adequate remuneration: Re Markwick's Patent, 13 Moore's P. C. 310: and the assignee of a patent applying for an extension does not, except under the special circumstance of his having materially assisted the inventor or enabled the patent to become of public utility, stand in the same favourable position as the inventor: Re Norton's Patent, 1 N. R. 557.

(h) Formerly the remedy of the patentee in case his patent were infringed, was dilatory and expensive, involving the double procedure of an action at law for the damages sustained from the invasion, and a suit in equity for an injunction to restrain the illegal use of the invention, and an account of the profits already made by the infringer from such use: Coryton, p. 263. But the Patent Law Amendment Act, 1852 (15 & 16 Vict. c. 83, s. 42), and the Common Law Procedure Acts of 1852 and 1854 (15 & 16 Vict. c. 99, s. 6; 17

8. Nothing herein contained shall prevent the said A. B. from using the said invention in any way he shall to be precluded think proper, in any place to which the letters patent to be obtained as aforesaid shall not extend.

10. A. B. not

from using the invention in foreign coun tries.

11. A. B. not to

be a partner with C. D. and E. F.

9. Nothing herein contained shall extend to constitute a partnership between the said A. B. and the said C. D. and E. F., or either of them, or give the said A. B., his executors or administrators, any right whatever to interfere with the affairs or business of the said C. D. and E. F., or either of them, further or otherwise than by requiring from time to time proper accounts of the returns and profits derived from the use of the said invention; and if the said A. B., his executors or administrators, shall do, or attempt to do, or cause to be done, anything in the character of a co-partner or co-partners (i) of the

Community of profits constitutes partner. ship.

& 18 Vict. c. 125, s. 46), empowering the Courts of Common Law to order the inspection of documents and machinery, and an account of profits, and to grant injunctions as well as to award damages, and Sir Hugh Cairns' Act (21 & 22 Vict. c. 27), introducing trial by jury into the practice of the Court of Chancery, have greatly simplified the remedies of a patentee.

(i) In framing agreements of the nature of that in the text, it is usually necessary to stipulate expressly, that no partnership shall be created between the parties; for the capitalists who are to work the patent seldom intend to admit the inventor into partnership with them or to allow him to interfere with the management of the business, and yet they do not choose to yield him any other remuneration than a share in the net profits to be derived from the use of the invention. But, in the absence of an express stipulation, an agreement to share the net profits of an undertaking, although one party alone is to bear the losses, constitutes a partnership in it: Lindley on Partnership, bk. i. c. i.; Ex parte Langdale, 18 Ves. 301; Gilpin v. Enderbey, 5 B. & Ald. 954; Bond v. Pittard, 3 M. & W. 357; and there may be a partnership in a patent: Lovell v. Hicks, 2 Y. & C. 472; Ridgway v. Philip, 1 C. M. & R. 415; Stocker v. Brocklebank, 3 M. & G. 250. Hence, when the inventor is to be paid by a share of the net profits, the capitalist should be protected against the interference of the patentee by express stipulation, that the agreement shall not constitute a partnership. On this point such a clause as that in

said C. D. and E. F., or either of them, or their or either of their executors or administrators, or shall interfere with their or either of their affairs or business (otherwise than as aforesaid), or with respect to the said letters patent and invention, or anything relating thereto, then and in any such case the said A. B. shall lose all right to receive any part of the profits of the said invention, and the whole of the profits to be derived from the said invention,



partners inter se may yet be liable as partners to third parties.

the text will be sufficient, so far as concerns the relative positions of the parties as between themselves: Stocker v. Brocklebank, supra, without affecting the right of third parties to treat them and to deal with them as partners: Waugh v. Carver, 2 H. Bl. 325; Gilpin v. Enderbey, Bond v. Pittard, ubi supra. The general result of the Persons not authorities seems to be, that persons who share the profits of a concern are primâ facie liable as partners to third persons, but that they may repel the presumption of partnership by showing that the legal relation of partnership inter se does not exist: Collyer's Law of Partnership, p. 63; and persons who have absolute knowledge that a party is not to be liable for loss sustained in a partnership cannot make him liable as a partner: Alderson v. Clay, 1 Camp. 404; Minnet v. Whiney, 5 Bro. P. C. 489; but see Brown v. Leonard, 2 Chit. 120.

It may be observed, that a partnership is not constituted by an agreement to share the gross profits of a concern: Dry v. Boswell, 1 Camp. 330; nor by one person being the mere servant or agent of another, and receiving a share of the profits in lieu of wages: Lindley's Law of Partnership, bk. i. c. i. ; nor by a person receiving interest on money lent or an annuity not varying with the profits: Grace v. Smith, 2 W. Bl. 99; Elgie v. Webster, 5 M. & W. 518; nor the receipt of a per-centage upon the gross amount of sales to customers recommended by the party: Pott v. Eyton, 3 C. B. 32; but the receipt of an annuity determinable on the ceasing of the trade or varying with the profits makes the annuitant a partner: Bloxam v. Pell, 2 W. Bl. 999; Er parte Wheeler, Buck., 48. Of course, an agreement that an inventor shall receive a fixed sum for each article made according to his patent, or a sum varying with the market price of the article, will not constitute him a partner. It is, however, difficult to enter into an agreement of this kind before the nature of the invention is disclosed. An agreement between the licensees of a patent and the inventor for securing the services of the inventor as manager at a per-centage on the profits will be found fully set out in Stocker v. Brocklebank, 3 M. & G. 250.

What circumstances do not constitute partnership.

B., his executors or administrators, and all interest in the said invention, and in the said letters patent, shall thenceforth belong to the said C. D. and E.
