How is the burden of proof handled for process patents?
If a product is identical to one made by a patented process, it is presumed to be made by that process. This presumption applies if the product is new or if there is a high likelihood the process was used. The defendant must then prove their process was actually different from the patented one. This rule on the burden of proof is in Section 78 Intellectual Property Code of the Philippines. “SEC. 78. Process Patents; Burden of Proof. – If the subject matter of a patent is a process for obtaining a product, any identical product shall be presumed to have been obtained through the use of the patented process…” January 3, 2026About Nicolas and De Vega Law Offices
