2016 Mercantile Law, Q3

ABC Appliances Corporation (ABC) is a domestic corporation engaged in the production and sale of televisions and other appliances. YYY Engineers, a Taiwanese company, is the manufacturer of televisions and other appliances from whom ABC actually purchases appliances. From 2000, when ABC started doing business with YYY, it has been using the mark “TTubes” in the Philippines for the television units that were bought from YYY. In 2015, YYY filed a trademark application for “TTubes.” Later, ABC also filed its application. Both claim the right over the trademark “TTubes” for television products. YYY relies on the principle of “first to file” while ABC involves the “doctrine of prior use.”
[a] Does the fact that YYY filed its application ahead of ABC mean that YYY has the prior right over the trademark? Explain briefly. (2.5%)
[b] Does the prior registration also mean a conclusive assumption that YYY Engineers is in fact the owner of the trademark “TTubes?” Briefly explain your answer. (2.5%)

1. First to File
Under Section 122 of the Intellectual Property Code of the Philippines (Republic Act Number 8293), rights in a mark are acquired through registration validly done in accordance with the provisions of the law. While the Philippines adopts the first-to-file system, prior filing or registration does not automatically confer trademark ownership if the application was filed in bad faith. A foreign entity or distributor that applies for registration of a mark with prior knowledge of another's established commercial use in the Philippines acts in bad faith, rendering its application or registration void and incapable of vesting superior trademark rights.

2. Rebuttable Ownership Presumption
Under Section 138 of Republic Act Number 8293, a certificate of registration of a mark serves as prima facie evidence of the registrant's ownership of the mark, the validity of the registration, and the registrant's exclusive right to use the mark. However, this statutory presumption of ownership is merely rebuttable and not conclusive. It can be overcome by clear evidence showing prior adoption, continuous commercial use, or bad faith on the part of the applicant. Registration obtained fraudulently or in bad faith confers no property rights and may be canceled upon proper petition.

3. Bad Faith Exception
Under Philippine trademark jurisprudence and Section 151 of the Intellectual Property Code, registration of a trademark in bad faith is a recognized ground for opposition or cancellation. Bad faith exists when an applicant registers a mark knowing that another person has prior commercial adoption and goodwill attached to the same or confusingly similar mark. An exclusive distributor or commercial buyer cannot register in its own name a foreign manufacturer's trademark without authorization, nor can a foreign manufacturer register a mark to usurp the goodwill established by a local user in bad faith.
