Trademark Confusion: Protecting Prior Use and Registration Rights

The Supreme Court recently reaffirmed that a trademark belongs to the one who first used and registered it, and that a later applicant cannot claim ownership of a confusingly similar mark. In Berris Agricultural Co., Inc. v. Norvy Abyadang (G.R. No. 183404, October 13, 2010), the Court protected the rights of a prior user and registrant against a subsequent applicant whose mark bore a dominant common feature. The ruling is a clear guide for businesses on how to secure and defend their marks under the Intellectual Property Code.

The Dispute

Berris Agricultural Co., Inc. (Berris) marketed a fungicide under the mark "D-10 80 WP," which it had used since June 20, 2002. It filed a trademark application on November 29, 2002, and obtained a certificate of registration on July 8, 2004.

In January 2004, Norvy Abyadang filed an application with the Intellectual Property Office (IPO) for the mark "NS D-10 PLUS," also for a fungicide with the same active ingredient, 80% Mancozeb. Berris opposed the application, arguing that "NS D-10 PLUS" was confusingly similar to its registered mark.

The IPO Bureau of Legal Affairs sustained the opposition and rejected Abyadang's application. The IPO Director General affirmed. However, the Court of Appeals reversed, ruling that the marks were not confusingly similar and that Berris had failed to prove ownership. The appellate court even ordered the cancellation of Berris's registration.

The Issue

The central question was whether Abyadang's mark "NS D-10 PLUS" was confusingly similar to Berris's "D-10 80 WP," and whether Berris had validly established ownership of its mark through prior use and registration.

The Ruling

The Supreme Court ruled in favor of Berris. The Court held that ownership of a trademark is acquired through registration and actual use. Under Section 122 of the Intellectual Property Code (Republic Act No. 8293), rights in a mark are acquired through valid registration with the IPO. A certificate of registration is prima facie evidence of the registrant's ownership and exclusive right to use the mark.

The Court found that Berris proved it had used the mark since June 20, 2002, even before filing its application. Its notarized Declaration of Actual Use (DAU), submitted to the IPO, stated this fact and was supported by sales invoices and official receipts. The Court gave full faith to this notarized document, noting that the burden to overcome its presumption of authenticity lies on the party contesting it.

Abyadang argued that Berris could not have legally sold its product in 2002 because it registered the product with the Fertilizer and Pesticide Authority (FPA) only in 2004. The Court dismissed this, stating that any violation of FPA rules is a separate matter from the IPO's jurisdiction over trademarks. Even a violation would not negate the evidence that Berris used the mark earlier.

Confusing Similarity

The Court applied two established tests for determining confusing similarity:

• The Dominancy Test, which focuses on the dominant features of the competing marks. Both marks share the component "D-10," which appears prominently on both packages. The Court found that "D-10" is the dominant feature of Berris's mark, and its presence in Abyadang's mark creates a likelihood of confusion.
• The Holistic or Totality Test, which considers the entire marks, including labels and packaging. Both products use the same type of foil packaging, identical color schemes (red, green, and white), and the same phrase "BROAD SPECTRUM FUNGICIDE."

Given these striking similarities, the Court concluded that buyers, mainly farmers, could be misled into thinking that "NS D-10 PLUS" was an upgraded formulation of "D-10 80 WP." The Court also noted that administrative agencies like the IPO, due to their expertise, are generally given great respect in their findings of fact.

Practical Takeaways

• Prior use matters. A trademark belongs to the one who first used it in trade or commerce, not merely to the one who first conceived or advertised it. Keep records of sales invoices, receipts, and customer orders as proof of actual use.
• Registration strengthens your position. While use creates rights, registration with the IPO provides prima facie evidence of ownership and exclusive use. File promptly and comply with the Declaration of Actual Use requirement within three years.
• A notarized DAU is powerful evidence. A notarized document filed with the IPO carries a presumption of regularity and authenticity. Contesting it requires clear, strong, and convincing evidence.
• Separate regulatory issues do not defeat trademark rights. Failure to register a product with another agency, such as the FPA, is a distinct matter and does not automatically invalidate evidence of trademark use.
• Common dominant features can create confusion. Even if marks differ in other respects, a shared dominant component—especially one placed at the beginning of the mark—can lead to a finding of confusing similarity, particularly for identical goods.
