Trademark Disputes: Unfair Competition and Prejudicial Questions in Philippine Law

The Supreme Court's 2016 decision in Caterpillar, Inc. v. Samson clarifies two important areas of Philippine litigation: when a civil case can suspend a criminal prosecution for unfair competition, and how courts review the Department of Justice's findings on probable cause. The ruling provides practical guidance for businesses involved in trademark disputes and their counsel.

The Dispute at a Glance

Caterpillar, Inc., a foreign manufacturer of footwear and clothing, accused Manolo P. Samson of unfair competition for selling products bearing marks similar to Caterpillar's core trademarks. Samson, however, held a 1997 registration for the "CATERPILLAR" trademark with the Intellectual Property Office.

The case spawned two separate legal fronts. First, Samson sought to suspend his criminal prosecution for unfair competition, arguing that a pending civil case for trademark cancellation raised a prejudicial question. Second, Caterpillar challenged the DOJ's finding of no probable cause to charge Samson with unfair competition.

The Prejudicial Question Issue

A prejudicial question arises when a civil case involves an issue so intimately connected with a criminal case that its resolution determines the accused's guilt or innocence. Under Section 7, Rule 111 of the Rules of Court, the civil action must have been instituted first, and its resolution must determine whether the criminal action may proceed.

Samson argued that the civil case for trademark cancellation—which would determine who lawfully owned the "CATERPILLAR" mark—should decide whether his criminal prosecution could continue.

The Supreme Court disagreed. The key distinction lies in the nature of the two actions. A trademark cancellation case determines the validity of registration. Unfair competition, however, does not depend on registration. The Court explained that unfair competition is committed when a person gives goods the general appearance of another's goods to deceive the public or defraud a competitor. The test is whether the act passes off one's goods as another's—registration is irrelevant. The exact statutory provision defining this offense is not available in the ASG law library, but the principle is well-established in the Court's ruling.

Independent Civil Actions Under Article 33

The Court also emphasized that the civil case was an independent civil action under Article 33 of the Civil Code. That provision allows an injured party to bring a civil action for damages in cases of fraud, entirely separate from any criminal prosecution. Since unfair competition involves fraud, the civil case could proceed independently. An independent civil action cannot serve as a prejudicial question to suspend criminal proceedings.

Reviewing Prosecutorial Findings on Probable Cause

The second issue concerned Caterpillar's challenge to the DOJ's dismissal of its criminal complaints. The investigating prosecutor found no probable cause, reasoning that Samson had registered the mark in 1997, had used it since 1992, and had established goodwill. The Secretary of Justice affirmed this finding.

Caterpillar appealed to the Court of Appeals via a petition for review under Rule 43 of the Rules of Court. The Court held this was the wrong remedy. The Secretary of Justice, when reviewing probable cause findings, performs an executive function—not a quasi-judicial one. The proper remedy is a special civil action for certiorari under Rule 65, which requires a showing of grave abuse of discretion.

The Court reiterated that the determination of probable cause lies exclusively with the Executive Branch through the public prosecutor and the Secretary of Justice. Courts will not interfere unless there is a clear showing of grave abuse of discretion—an arbitrary, capricious, or whimsical exercise of judgment amounting to lack of jurisdiction. Caterpillar failed to make such a showing.

Practical Takeaways

• Registration matters, but not for unfair competition. A valid trademark registration does not automatically shield a seller from an unfair competition claim if the seller's acts deceive the public.
• Know the correct remedy. To challenge a DOJ finding on probable cause, file a petition for certiorari under Rule 65 alleging grave abuse of discretion—not a Rule 43 appeal.
• Independent civil actions proceed alongside criminal cases. Where fraud is involved, a civil suit for damages can run concurrently with a criminal prosecution; it does not create a prejudicial question.
• Prosecutors have wide discretion. Courts generally defer to the DOJ's probable cause determinations, so litigants must present compelling evidence of grave abuse to obtain judicial review.
