G.R. No. L-19441; June 30, 1964
SHELL COMPANY OF THE PHILIPPINES, LTD., petitioner, vs. INSULAR PETROLEUM REFINING CO., LTD., and COURT OF APPEALS, respondents.

FACTS

Petitioner Shell Company is a corporation engaged in selling petroleum products, including lubricating oil, with its trademark on its containers. Respondent Insular Petroleum Refining Co., a registered limited partnership, is in the business of collecting and refining used lubricating oil, which it markets at a lower price than new oil. Insular produces two types: a high-grade oil sold in its own specially sealed containers, and a low-grade oil sold in miscellaneous used containers. Insular’s general manager testified that for low-grade oil, they generally use various used drums, including those formerly belonging to other companies like Shell, after obliterating the original markings.
The case centers on a single transaction where Insular’s agent, F. Pecson Lozano, sold one drum of its low-grade “Insoil” oil to Conrado Uichangco, a Shell service station operator. This specific drum still bore the Shell marking, as the obliteration was not done. The evidence showed that Lozano presented Insoil oil as a good, cheaper alternative, and Uichangco, after consulting a Shell manager who requested a sample, ordered one drum. Uichangco explicitly stated he did not want to cheat his customers and subsequently resold the drum to Shell itself, not to the public. The invoice described the goods as “Insoil Motor Oil (straight mineral) SAE 30.”

ISSUE

Whether the act of respondent Insular in selling its low-grade oil in a container bearing petitioner Shell’s trademark, under the circumstances of the single proven transaction, constitutes unfair competition.

RULING

The Supreme Court, affirming the Court of Appeals, ruled that there was no unfair competition. The legal logic is anchored on the absence of the essential element of deceit or passing off one’s goods as those of another. For unfair competition to exist, there must be a fraudulent intent to deceive the public by causing confusion between the products of the defendant and those of the plaintiff.
The Court found that in the isolated transaction, respondent’s agent made no misrepresentation that the oil was Shell oil; he explicitly sold it as “Insoil” oil, as clearly stated on the invoice. The buyer, Uichangco, was fully aware he was purchasing Insoil oil, and the drum was never passed off to the public as Shell oil, as it was ultimately resold to Shell company itself. The acquittal in the related criminal case for violation of Article 189 of the Revised Penal Code, due to lack of deceit, bolstered this finding.
The Court rejected Shell’s argument that the mere use of its container was inherently deceptive. It emphasized that respondent’s general practice was to obliterate markings, and this single instance was an anomaly. More critically, the Court held that any potential deception would occur only if a Shell dealer, like Uichangco, subsequently sold the Insoil oil as Shell oil to consumers—an act for which the dealer, not respondent Insular, would be legally responsible. There was no evidence of connivance between Uichangco and Lozano to perpetrate such fraud. Consequently, without proof of intent to deceive the public, the action for unfair competition cannot prosper.
