Patent Registration in the Philippines: A Foreigner’s Guide

In today’s globalized world, innovation knows no borders. Inventors from all over the world might seek patent protection in the Philippines for their creations. This blog post will provide a roadmap for foreign applicants navigating the Philippine patent registration process, offering a holistic view compared to their home countries’ systems.

Understanding Philippine Patent Law

The Philippines follows a first-to-file system, similar to many other countries. This means the inventor who files a patent application first gets priority, even if someone else invented it earlier but still needs to file. The Intellectual Property Office of the Philippines (IPOPHL) is responsible for processing patent applications.

Foreigner vs. Domestic Applicant

The process for foreign applicants is generally similar to that of domestic applicants. However, there are a few key differences:

  • Representation: Foreign applicants are required to appoint a registered patent agent or lawyer in the Philippines to represent them throughout the process.
  • Priority Documents: If claiming priority from a previously filed application in another country, a certified copy of the priority document and its translation must be submitted within three months of filing the Philippine application.

Roadmap to Patent Filing

  1. Invention Disclosure: Carefully document your invention with detailed descriptions, drawings, and prototypes (if possible) to ensure clarity and completeness of the application.
  2. Patentability Search: Conduct a patentability search to assess if your invention meets the requirements for patentability in the Philippines. This includes novelty, inventive steps, and industrial applicability. Consider consulting a patent attorney to guide you through this process.
  3. Application Filing: Prepare and file a patent application with IPOPHL. This includes the application form, specifications, claims, drawings, and any necessary fees.
  4. Examination and Prosecution: IPOPHL will examine your application to ensure it meets all the requirements. You may need to respond to any objections raised by the examiner during this stage. This back-and-forth communication is called prosecution.
  5. Grant or Rejection: If the application meets all the requirements, IPOPHL will grant a patent. However, if it is rejected, you can appeal the decision.

Holistic View Compared to Foreign Systems

  1. Novelty Grace Period: Unlike some countries, the Philippines does not offer a grace period for novelty. This means any public disclosure of your invention before applying can destroy its novelty.
  2. Term of Patent: The term of a patent in the Philippines is 20 years from the filing date.
  3. Patent Cooperation Treaty (PCT): The Philippines is a member of the PCT, which allows you to file a single international application for patent protection in multiple countries, including the Philippines.


Obtaining patent protection in the Philippines can be a valuable step for foreign inventors looking to expand their reach in Southeast Asia. By understanding the key differences between the Philippine system and their home country’s system and by following a well-defined roadmap, foreign applicants can increase their chances of successfully securing a patent in the Philippines. Remember, consulting with a registered patent agent or lawyer familiar with both Philippine and foreign patent law is highly recommended throughout the process.
