He quotes Justice Heath, who said—
“That which is the subject of a Patent ought to be vendible; otherwise it cannot be a new manufacture.”
So Tyndal—
“That it is a manufacture can admit of no doubt: it is a vendible article, produced by the art and hand of man.”
Mark from the words of Justice Buller, on the same occasion, the sentiment which was permitted to prevail and neutralise the statute:—
“Few men possess greater ingenuity, or have greater merit. If their (Boulton and Watt’s) Patent can be sustained in point of law, no man ought to envy them the profit and advantages arising from it. Even if it cannot be supported, no man ought to envy them the profit,” &c.
We come to C. J. Eyre:—
“According to the letter of the statute, the words ... fall very short ... but most certainly the exposition of the statute, so far as usage will expound it, has gone very much beyond the letter. ‘A deliberate surrender,’ comments Mr. Coryton, ‘of judicial power in favour of an accumulation of popular errors.’... Later judges, following in the same course, have striven rather to regulate the inconsistencies they found, than to address themselves to the cause and thus prevent the possibility of their recurrence. Writers on this subject have on this head followed in the course indicated by the Bench.”
A practical commentary, and a confirmation of Mr. Coryton’s views, are furnished by the fact that the number of Patents granted in the six reigns preceding that of Geo. III. was only 540 in 85 years, or less than 6½ a-year; whereas now a greater number is granted daily.
