G.R. No. L-4234 May 21, 1952
ABBOT LABORATORIES, petitioner, vs. HON. CELEDONIO AGRAVA, Director of Patents, respondent.

FACTS

Petitioner Abbot Laboratories, a Philippine corporation, appealed the decision of the Director of Patents disallowing Patent Application Serial No. 77 for an invention relating to a medical preparation known as “Tridione.” The application was submitted in June 1948 by Abbot Laboratories of Illinois, U.S.A., claiming priority rights under Section 76 of Republic Act No. 165 (Philippine Patent Law) based on three earlier U.S. patent applications filed by the inventor. The Director of Patents denied the request for priority on the ground that it was filed after the deadline of February 28, 1948. Petitioner contended the correct deadline was July 1, 1948, as stated in Section 76. The Director’s position was based on an executive agreement, through exchanged diplomatic notes between the U.S. Secretary of State and the Philippine Ambassador, which set the reciprocal deadline for priority rights for citizens of both countries at February 29, 1948. Petitioner argued that the Executive Branch had no power to abridge the statutory period fixed by law.

ISSUE

Whether the Director of Patents correctly denied the request for priority rights by applying the deadline of February 29, 1948, as established through diplomatic notes, instead of the July 1, 1948 deadline stated in Section 76 of the Patent Law.

RULING

The Supreme Court affirmed the decision of the Director of Patents. The Court held that the exchanged diplomatic notes did not amend or abridge Section 76 but constituted a proper interpretation and application of its reciprocity provision. Section 76 is a reciprocity measure, granting priority rights to foreigners only if their countries extend substantially reciprocal privileges to Philippine citizens. The notes established that, under U.S. law (the Boykin Act), Filipinos could only claim such priority rights until February 29, 1948. Therefore, as of June 1948 when the petitioner filed its application, Filipinos no longer enjoyed reciprocal privileges in the U.S. Consequently, an American applicant could not invoke Section 76 at that time. The Court found no alteration of the statutory limit; the Director merely correctly applied the principle of reciprocity. The July 1, 1948 date in the law is the ultimate expiry date, but priority rights are contingent upon the existence of reciprocal privileges at the time of application. Since the petitioner’s priority claim failed, the Court deemed it unnecessary to resolve a subordinate issue regarding the invention’s patentability or a procedural question on the petitioner’s personality to appeal.
