It is to be noted that neither the sublease nor the bill of sale give the plaintiff any rights with respect to the use of the trade name “The Royal” or “Royal Ready-to-Wear.” The only reference to “Royal” is that used for descriptive reference to the defendant and the defendant’s store name to establish the location of the premises in the lease. The plaintiff acquired no right to the use of the name from either the bill of sale or the sublease. It is not disputed that the defendant has a property right in the name which is valuable and upon which he has spent considerable money in its development and registration. R. L., c. 186, s. 10; R. L., c. 207-A, as inserted by Laws 1949, c. 219. Although the defendant permitted and encouraged the use of the trade name for the purposes of advertising and sales, this did not convert a revocable license into an irrevocable grant or raise an estoppel against the defendant. Conway Bank v. Pease, 76 N. H. 319.
The record shows that much confusion in the public mind and in the mind of creditors has resulted from joint use of the trade name, “The Royal” and “Royal Ready-to-Wear.” This has affected credit ratings, good will and business reputation. The defendant could properly revoke the permission to use the trade name which he originally allowed. Batchelder v. Hibbard, 58 N. H. 269. The plaintiff did not buy the trade name and is not entitled to continue to use it to the damage of the defendant and to the confusion of the public. Nardini &c. Co. v. Sterling Co., 93 N. H. 364; Purcell v. Summers, 145 F. (2d) 979; Restatement, Torts, ss. 717, 730.
The decree is affirmed in all respects except as it relates to use of trade names wherein the defendant is entitled to a decree in his favor.
Decree affirmed in part and reversed in part.
All concurred except Duncan, J., who was in doubt as to part I.
