ZUNECA PHARMACEUTICAL, AKRAM ARAIN AND/OR VENUS ARAIN, M.D. DBA ZUNECA PHARMACEUTICAL, PETITIONERS, VS. NATRAPHARM, INC., RESPONDENT.

Zuneca Pharmaceutical versus Natrapharm

The Case

This is a petition for review under Rule 45 of the Rules of Court, brought by Zuneca Pharmaceutical and its owners against Natrapharm, Incorporated. Natrapharm manufactures and sells a medicine with the generic name Citicoline, indicated for heart and stroke patients, and markets it under the registered trademark Zynapse. Zuneca, on the other hand, imports and sells an anti-convulsant with the generic name Carbamazepine, indicated for epilepsy, under the brand name Zynaps. The two marks are pronounced exactly alike. Natrapharm sued for trademark infringement and asked for a temporary restraining order and a writ of preliminary injunction. The case matters because it draws the sharp line between a preliminary injunction, which is merely ancillary and provisional, and a permanent injunction, which is a judgment on the merits — and it tells us what happens when a petition questioning the denial of the former is overtaken by a decision on the latter.

Procedural History

Natrapharm filed its complaint for trademark infringement with a prayer for a temporary restraining order and a writ of preliminary injunction before the Regional Trial Court of Quezon City. The trial court denied the temporary restraining order, ruling that even if Natrapharm registered Zynapse with the Intellectual Property Office in 2007, that registration was defeated by Zuneca's prior actual use of Zynaps in 2003. The trial court likewise denied the writ of preliminary injunction, holding that neither party was entitled to injunctive relief at that point, and that Section 159 of the Intellectual Property Code curtails the registrant's rights against a prior user in good faith.

Natrapharm went up to the Court of Appeals by petition for certiorari, with an application for a temporary restraining order and a writ of preliminary injunction. The Court of Appeals initially denied that application, finding no clear and existing right shown, and denied reconsideration. But in its later Decision, the Court of Appeals granted the petition, reversed the trial court, and entered a permanent injunction against Zuneca's use of Zynaps. Zuneca's motion for reconsideration was denied. Hence this petition for review before the Supreme Court. In the meantime, the trial court rendered a decision on the merits of the infringement case, finding Zuneca liable for damages and enjoining the use of Zynaps. Natrapharm then moved to dismiss this petition as moot and academic.

Facts

Natrapharm is an all-Filipino pharmaceutical company. It manufactures and sells Citicoline under the trademark Zynapse, which it registered with the Intellectual Property Office on September 24, 2007, and it obtained from the Bureau of Food and Drugs all the permits and licenses needed to sell the product.

Unknown to Natrapharm, Zuneca had been selling Carbamazepine, an anti-convulsant for epilepsy imported from Lahore, Pakistan, under the brand name Zynaps since 2003 or even as early as 2001. Zynaps is not registered with the Intellectual Property Office, but Zuneca held a Certificate of Product Registration from the Bureau of Food and Drugs issued on April 15, 2003, after it applied on October 2, 2001. Zynaps is pronounced exactly like Zynapse, and both medicines are sold in the same drugstores. Natrapharm warned that Carbamazepine has a serious and disfiguring side effect called Stevens-Johnson Syndrome, so that medicine switching between the two products would place patients in greater danger.

On October 30, 2007, Natrapharm sent a cease-and-desist demand. Zuneca refused, invoking its prior use and its certificate of product registration. Natrapharm then filed its complaint for infringement on November 29, 2007.

Issues

• Whether or not the decision on the merits rendered the issues in this case moot and academic.
• Whether or not the Court of Appeals may order a permanent injunction in deciding a petition for certiorari against the denial of an application for a preliminary injunction issued by the trial court.

Applicable Provisions

Section 1 of Rule 58 of the Rules of Court defines a preliminary injunction:

SECTION 1. Preliminary injunction defined; classes. — A preliminary injunction is an order granted at any stage of an action or proceeding prior to the judgment or final order, requiring a party or a court, agency or a person to refrain from a particular act or acts. It may also require the performance of a particular act or acts, in which case it shall be known as a preliminary mandatory injunction.

This provision fixes the provisional character of the writ that was the sole subject of the petition below.

Section 9 of the same Rule defines when a final injunction is granted:

SEC. 9. When final injunction granted. — If after the trial of the action it appears that the applicant is entitled to have the act or acts complained of permanently enjoined, the court shall grant a final injunction perpetually restraining the party or person enjoined from the commission or continuance of the act or acts or confirming the preliminary mandatory injunction.

This provision ties the permanent injunction to a trial and to a judgment on the merits, which is the pivot of the Court's ruling.

Section 159 of the Intellectual Property Code states the limitations on actions for infringement:

SEC. 159. Limitations to Actions for Infringement. - Notwithstanding any other provision of this Act, the remedies given to the owner of a right infringed under this Act shall be limited as follows: 159.1. Notwithstanding the provision of Section 155 hereof, a registered mark shall have no effect against any person who, in good faith, before the filing date or the priority date, was using the mark for the purposes of his business or enterprise.

This was the provision Zuneca invoked, and on which the trial court relied in denying the injunctive relief.

Ruling

On the first issue, the Court held that the issues had indeed been rendered moot and academic by the trial court's decision on the merits. The case brought to the Court of Appeals involved only the denial of an application for a writ of preliminary injunction, a mere ancillary writ. Since a decision on the merits had already been rendered, and that decision itself included a permanent injunction in its disposition, the proper remedy was an appeal from the decision in the main case, not this petition.

On the second issue, the Court explained the nature of each writ. A writ of preliminary injunction is generally based solely on initial and incomplete evidence. The evidence submitted at the hearing is not conclusive or complete, for only a sampling is needed to give the trial court an idea of the justification for the writ pending the decision on the merits. Its findings are interlocutory, made even before trial is commenced or terminated. By contrast, a permanent injunction forms part of the judgment on the merits and can properly be ordered only on final judgment, after a trial or hearing on the merits. A preliminary injunction, like any interlocutory order, cannot survive the main case of which it is an incident; it loses its force and effect after the decision in the main petition. The Court cited its earlier ruling in Casilan versus Ybañez, where a preliminary writ had already been vacated, being superseded and replaced by the permanent injunction ordered in the decision on the merits, and where the obvious remedy was a timely appeal from the judgment on the merits.

Doctrine

A preliminary injunction is provisional and interlocutory. It is issued before judgment, on incomplete evidence, and it cannot survive the main case of which it is an incident. A permanent injunction, under Section 9 of Rule 58, is a judgment on the merits; it may be granted only after trial, and it supersedes and replaces any preliminary writ. Consequently, once the trial court renders a decision on the merits that includes a permanent injunction, a petition questioning only the denial of a preliminary injunction becomes moot and academic, and the remedy is an appeal from the judgment on the merits. The prior-user defense under Section 159.1 of the Intellectual Property Code is a matter for trial on the merits, not for resolution on a preliminary writ.

Disposition

The petition was denied for being moot and academic, leaving the decision on the merits, with its permanent injunction, as the proper subject of an appeal.

Remember This

Memorize this line: a preliminary injunction is ancillary and dies with the main case, while a permanent injunction is a judgment on the merits that supersedes it. Examiners use this case to test the distinction between preliminary and permanent injunction under Rule 58, and to ask what remedy lies when a decision on the merits overtakes a petition questioning an ancillary writ.
