Important Note: While Filipinos have made significant contributions in various fields, recognizing them as inventors is sometimes debated due to factors like lack of formal patent applications or insufficient documentation.
This list is not exhaustive, and there are many other Filipino inventors who have made important contributions to science and technology. However, these individuals represent some of the most notable figures who have brought innovation and progress to the Philippines and the world.
