Grave difficulties, however, seem to me to attend any attempt to apply s. 110A (2) to the case of a grant to a natural person and a corporation as co-owners, and I am of opinion that it cannot be so applied. It is clear that the sub-section does not expressly provide for the devolution of the interest of a corporate co-owner which has been dissolved. The concluding words seem to me plainly to refer only to the death of a natural person: a corporation does not "die", nor can it have "personal representatives". These concluding words, indeed, seem to indicate that the case of a corporate co-owner is excluded altogether from the contemplation of the section. It is said, however, that the case has been already covered by the general provision that "they shall be treated, for the purpose of the devolution of the legal interest therein, as joint tenants." But these words can have no meaning except by reference to the common law, and it seems to be established that at common law there could be no such thing as a joint tenancy between two corporations aggregate or between a corporation aggregate and a natural person. A grant to two corporations or to a corporation and a natural person could at common law create nothing but a tenancy in common. So far as land is concerned, the reasons for this (though technical) seem clear enough, and I think I must take it, in the light of the decision of Mathew J. in Law Guarantee & Trust Society Ltd. v Governor and Company of Bank of England [1] that the same rule applies where personalty is concerned. Since there can at common law be no such thing as a joint tenancy between a corporation and a natural person, the conception of a jus accrescendi, for the purposes of which the dissolution of a corporation has the same effect as the death of a natural person, is entirely foreign to the common law, and it seems to me impossible to regard the words "shall for the purposes of devolution be treated as joint tenants" as saying or implying that, where a corporation is a co-owner, its dissolution shall have the same effect, with respect to devolution, as the death of a natural "joint" owner. The true position, as I see it, is that the grant to the corporation and the natural person is a grant to them as tenants in common, and the application of the provision in question is really, in effect, excluded by the words "unless otherwise specified in the patent". That the case of a corporate co-owner should be overlooked is perhaps not altogether surprising. The sub-section is taken verbatim from s. 37 of the English Act of 1907, and at that time in England a corporation could apply for a patent only in limited and exceptional classes of case. An assignee of an invention could not apply as such, and a corporation could not, it was held, be a "true and first inventor", because it had no corporate mind with which it could conceive an invention. It would not at that time be unnatural, I think, for the draftsman in England to be thinking only of "true and first inventors."
