This was an action to foreclose a mechanic’s lien. Plaintiffs and •respondents agreed to install in the building of 'the defendant and ap
No judgment shall be entered herein until plaintiff shall furnish-to the defendant Arundel Realty Company a certificate from the-Automatic Pleating Company of license to said defendant to use-the Paul vacuum system for circulating steam in said building.
Prom an order denying defendant’s motion for a new trial this appeal was taken.
The trial court held, as appears in its findings of fact and conclusions of law, that the plaintiffs had procured a license.
“The license is an implied one, but it is as effective as any express, license couid be. * * * The rule applicable here is that the purchaser of a patented article from the patentee, or other person authorized to sell, ordinarily acquires by his purchase an unrestricted right to-use the patented article. * * * A license may be inferred by the acquiescence by the patentee in the use of the patented article. 22 Am. & Eng. Enc. of Law, 432, 433.” He concluded “that the defendant has an indisputable right to use the plant and system as installed free from any interference from the owner of the patent or any other person.”
The contractor will run all the necessary air piping for equipping the entire building with the Paul vacuum system for circulating steam at or below the atmospheric pressure, and furnish license to use the system.
We agree with the defendant that this requires a written license or ■certificate of license to use this system; that the clause “furnish license to use the system” was not equivalent to an agreement that the parties would so conduct themselves as to work an estoppel upon the owner of the heating system, and thereby secure in effect a license, and to protect the defendant against an infringement suit or any interference. We think, however, that the trial court was right in regarding this as largely a matter of form. The defendant was entitled to that certificate, 'however, and his right in this regard was protected by the requirement ■of its production as a condition precedent to the entry of the judgment. When this formal defect is supplied, the contract will have been substantially performed. The case accordingly falls within the familiar rule entitling a building contractor to a mechanic’s lien upon the substantial performance of his contract, and despite some slight omission ■or defects which were not so essential as to defeat his claim, or, as it is sometimes said, do not go to the root of the subject-matter of the contract, but are easily susceptible of remedy.
