International Patents: How Does the PCT Work?

There is no single worldwide patent: protection is granted through national or regional systems. A Patent Cooperation Treaty application provides a coordinated international filing route, not a global patent grant.

What does a PCT application accomplish?

It creates an international application process that includes a search and written opinion. National or regional offices ultimately decide whether to grant protection under their laws.

How does an earlier filing affect timing?

For utility inventions, a PCT filing claiming priority is generally due within 12 months of the first filing. Disclosure history, valid priority claims and applicable rules need careful review.

When do national filings become necessary?

National-phase entry is commonly due around 30 months from the earliest claimed priority, with jurisdiction-specific variations. Confirm each office's deadline, translation requirements and local representation rules.

Choose markets based on customers, manufacturing, competitors and enforcement practicality. Budget for translations, local counsel and ongoing prosecution rather than just the initial international filing.
