CASE DIGEST: Vargas vs. FM Yaptico

ANGEL VARGAS vs F. M. YAPTICO & CO. (Ltd.)

G.R. No. 14101, September 24, 1919

Facts:

Plaintiff Angel Vargas, a farmer, was issued patents by the United States Patent Office for his so-called invention of an improved adjustable plow with the use his own native plow. A certified copy of the patent was filed in the Division of Patents, Copyrights, and Trademarks of the Executive Bureau, Government of the Philippine Islands.

Defendant F. M. Yaptico & Co. (Ltd.), a firm engaged in the foundry business in Iloilo City, was a manufacturer of plow parts. It produced points, shares, shoes, and heel pieces in a considerable amount adapted to replace worn-out parts of the Vargas plow.

Vargas filed a case in the Court of First Instance of Iloilo to enjoin the alleged infringement of his U.S. Patent by the defendant F. M Yaptico & Co. (Ltd.), and to recover the damages suffered by reason of this infringement, to which the court issued the preliminary injunction prayed for.

The defendant denied the allegations and defended that the patent lacked novelty or invention, that there was no priority of ideas or device in the principle and construction of the plow, and that the plow, whose manufacture it was sought to have enjoined by the plaintiff, had already been in public use for more than two years before the application of the plaintiff for his patent.

The trial judge rendered judgment in favor of the defendant, declaring null and without effect the patent in question and dismissing the suit with costs against the plaintiff. Hence, the plaintiff appealed said judgment.

Issues:

1. Whether the patented invention is void for lack of novelty and invention?

2. Whether the patent is invalid considering that the plow had already been in public use for over two years prior to the application for a patent.

Ruling:

1. Yes, the patent if void. The Supreme Court affirmed the trial court’s conclusion that the plow of the plaintiff is not different from the native plow, except in the material, in the form, in the weight and the grade of the result, the said differences giving it neither a new function nor a new result distinct from the function and the result obtained from the native plow. Also, its production does not presuppose the exercise of the inventive faculty but merely of mechanical skill, which does not give a right to a patent of an invention under the provisions of the Patent Law.

2. Yes, the patent is void. Under the provisions of the statute, an inventor's creation must not have been in public use or on sale in the United States (and the Philippine Islands) for more than two years prior to his application.

Further, it was proved that the invention was used in public at Iloilo by others than Vargas, the inventor, more than two years before the application for the patent thus, the patent is invalid.
