Securing International Protection for Nanomaterial-Based Medical Devices

In today’s globalized world, innovation isn’t confined to one’s home country. When your medical device is designed for global markets, international patent protection becomes indispensable.

Understanding the Patent Cooperation Treaty (PCT)

The PCT is an international treaty that enables inventors to seek patent protection for their inventions in multiple countries through a single “international” patent application. This provides you with a streamlined process before pursuing patents in specific countries.

  • Advantages:
  • Time-saving as it postpones the need to file separate applications in each country of interest for up to 30 months from the earliest filing date.
  • Offers a preliminary assessment of your invention’s patentability.
  • Considerations:
  • While PCT isn’t a global patent grant, it’s a bridge to national applications in member states. After the PCT process, you’d still need to pursue individual patents in countries of interest.

Navigating Differences in Patent Laws

Different countries have diverse patent laws, especially concerning medical devices and innovations. Some key differences startups should be aware of:

  • Definition of Novelty: Some countries have an absolute novelty requirement, meaning any public disclosure before filing jeopardizes patentability. Others might offer grace periods.
  • Inventive Step or Non-obviousness: The threshold for what constitutes an “inventive step” can vary, influencing patent grants.
  • Compulsory Licensing: Some nations can mandate licensing of patents, especially if it’s in public interest, which can impact medical devices deemed essential.

Engaging Local Patent Counsels

When seeking international patent protection, collaborating with local patent counsels in target countries is beneficial. They can:
