Chung Te v. Director of Patents
REITERATIONFacts
The Antecedents: Petitioner Chung Te and respondent Ng Kian Giab both applied for the registration of the trademark "Marca Piña" and its representation. Chung Te claimed use since January 8, 1951, on undershirts, T-shirts, and baby dresses, while Ng Kian Giab claimed use since December 6, 1955, on undershirts. An interference was declared due to the confusing similarity of the trademarks. Procedural History: The Director of Patents declared that neither party satisfactorily adduced definite proof of their asserted dates of first use. Relying on the rule that in such cases, the date of first use is confined to the filing date, the Director granted the application of the senior party, Ng Kian Giab, and rejected Chung Te's application. Chung Te's motion for reconsideration was denied, leading to the present appeal. The Appeal: Chung Te appealed to the Supreme Court, averring that the Director of Patents erred in not giving due weight to his documentary evidence proving use since 1951, in not finding that Ng Kian Giab admitted use only in 1955, in disregarding Chung Te's prior abandoned application, and in declaring Ng Kian Giab the prior user without substantial evidence.
Issue(s)
Whether the Director of Patents erred in disregarding the evidence presented by both parties and relying solely on filing dates to determine priority of use. Whether petitioner Chung Te established prior adoption and use of the trademark "Marca Piña" over respondent Ng Kian Giab.
Ruling
The Supreme Court reversed the decision of the Director of Patents. It found that petitioner Chung Te had established prior use and adoption of the trademark "Marca Piña" and ordered its registration in his name. The resolution enjoining petitioner to comply with the appealed decision was set aside.
Ratio Decidendi
On the issue of disregarding evidence and relying on filing dates: The Court found that the Director of Patents erred in disregarding all evidence presented by both parties. While the rule that filing dates shall be confined to the application date applies when neither party satisfactorily proves their asserted date of first use, the Court noted that the testimonial and documentary evidence presented by Chung Te tended to show use as early as February 1952. Furthermore, Chung Te's previously abandoned application (Application No. 5544, filed March 31, 1957) could be considered cogent evidence of his assertion of use as of its filing date, especially when the Director relied solely on filing dates. The Court found the evidence for both parties was not entirely unreliable, contrary to the Director's conclusion. On whether petitioner Chung Te established prior adoption and use: The Court was convinced that petitioner Chung Te had established prior use and adoption of the trademark "Marca Piña." The Court meticulously detailed Chung Te's evidence, including testimony from Jose Lim regarding the groundwork in January 1951, Julieta Francisco's testimony about sewing labels since 1951, membership in the Philippine Chinese Underwear Manufacturers Association in November 1951, business permits and tax payments in early 1952, registration as a private merchant in February 1952, and substantial purchases of labels and boxes from 1952 onwards. The Court also noted sales receipts from February 1, 1952, supported by customer testimony. In contrast, the Court found respondent Ng Kian Giab's testimonial evidence insufficient to prove use prior to 1955, noting inconsistencies and the burden of proof required when attempting to carry back the date of first use beyond what was initially stated in the application. The documentary evidence for Ng Kian Giab, such as business tax receipts and applications for business name registration, clearly indicated his use began in late 1955.
Main Doctrine
The Court reiterated that in trademark registration cases, priority of adoption and use is the decisive factor. The party claiming earlier use bears the burden of proving it with clear and convincing evidence. The decision emphasizes the superior weight of documentary evidence, such as business permits, tax receipts, and purchase orders for labels, in establishing claims of priority, especially when contrasted with testimonial evidence that may be inconsistent or self-serving. The ruling also clarifies that an abandoned application, while not determinative of priority in an interference proceeding, can still serve as evidence of the applicant's assertion of use as of its filing date when other evidence is disregarded.
