De la Paz v. Director of Patents and Petrophil Corporation
REITERATIONFacts
The Antecedents: Respondent Petrophil Corporation filed a petition for cancellation of letters of patent for Invention No. 14132, issued to petitioner Adrian S. de la Paz, on the ground that the invention was not patentable. Procedural History: After petitioner filed an answer and the parties failed to settle, respondent Petrophil adduced its evidence. Petitioner then filed a motion to dismiss, in effect a demurrer to the evidence, alleging insufficient evidence. The Director of Patents denied this motion, and a subsequent motion for reconsideration was also denied. The Petition: Petitioner filed a petition for certiorari, alleging that the Director of Patents committed grave abuse of discretion in denying the motion to dismiss, as there was clearly no cause of action.
Issue(s)
Whether the Director of Patents committed a grave abuse of discretion in denying the motion to dismiss. Whether a motion to dismiss based on lack of cause of action is permissible in patent cancellation proceedings under the Rules of Practice on Patent Cases.
Ruling
The petition is dismissed for lack of merit. The Director of Patents did not commit a grave abuse of discretion.
Ratio Decidendi
On whether the Director of Patents committed a grave abuse of discretion: The Court held that the matter of granting or denying a motion to dismiss is addressed to the sound discretion of the respondent Director of Patents. Unless there is a showing of grave abuse of discretion, the appellate court should not disturb the action of the Director. The petitioner failed to discharge his burden of proving such grave abuse of discretion. The denial was based on procedural rules designed to promote the resolution of cases on their merits after all evidence has been presented. The Director's observation that the case was nearing termination and that matters still needed to be threshed out supported the denial, aligning with the procedural rules. On whether a motion to dismiss based on lack of cause of action is permissible: The Court ruled that under Rule 184-C(d) of the Rules of Practice on Patent Cases, no motion to dismiss on any of the grounds enumerated in the Rules of Court shall be entertained. Instead, such grounds, including lack of cause of action, must be pleaded as affirmative defenses, the resolution of which shall be made in the decision on the merits. Furthermore, Rule 184-G explicitly states that no demurrer to evidence shall be entertained after the presentation of the petitioner's evidence. The petitioner's motion, which was in the nature of a demurrer to the evidence, was therefore impermissible under these specific rules governing patent cases. These rules, promulgated by the Bureau of Patents pursuant to law, control the procedure in that office and prevail over suppletory application of the Rules of Court.
Main Doctrine
A motion to dismiss based on the ground of lack of cause of action, in patent cases, must be pleaded as an affirmative defense and resolved in the decision on the merits, pursuant to the Rules of Practice on Patent Cases, and not entertained as a motion to dismiss or a demurrer to evidence.
