Petitioner moves for leave to sue the receiver of the Industrial Furnace Corpo *919 ration and. the Industrial Furnace Corporation to' rescind the assignment to such corporation of two patents, executed on September 30, 1930. The Industrial Corporation was organized to manufacture and ■sell electrical furnacés and to develop and manufacture certain processes for the manufacture of what is known as Z-Metal. Originally the corporation was licensed to use certain patents owned by petitioner upon the agreement of the corporation to pay petitioner $2 per hour of rated capacity. This agreement was canceled or modified and the corporation given an option to buy the patents in question for $75,000. Still later, another agreement was made whereby the corporation agreed that the royalty of $2 per hour of rated capacity to the amount of $5,000 as a minimum amount should be paid petitioner till $75,000 had been paid, and thereafter petitioner was to receive a royalty of $2 per kilowatt hour. This final agreement was made September 30, 1930. The minimum royalties were paid until and including the year 1932. No further royalties have been paid save $3,-063.46 paid in 1933. It is claimed that there is now due petitioner $10,686.54. On March 16, 1934, a receiver for the corporation was appointed, and such appointment continues to this time.
It is petitioner’s contention that he is entitled to a rescission of the patent assignment agreement because of the failure of the corporation and the receiver to pay the stipulated royalties. It is the receiver’s contention that, since the assignment contains no forfeiture clause, the agreement cannot be rescinded, and that the case is lacking in equity.
It is my opinion that this motion should be granted for these reasons.
While some discretion rests in the court in deciding motions for leave to sue a receiver, leave to sue cannot arbitrarily be refused, and should be -granted where it is made to appear that a cause of action is stated upon which it can be said there is reasonable probability of recovery. Petitioner must show a.prima facie cause of action and right of recovery. American Loan & Trust Co. v. Central Vermont R. R. Co. (C.C.)
There are numerous authorities in the state and federal courts that, where a patent is sold to be paid for on a royalty basis, a condition is implied that the patent will be worked to earn the stipulated royalties. Brewster v. Lanyon Zinc Co. (C.C.A.)
It seems to me that the case of In re Waterson, Berlin & Snyder Co. et al. (Fain v. Irving Trust Co.),
Hartshorn v. Day,
It appears to me that a prima facie case is made on the proofs before me, and that the motion should be granted.
