For design patent applications, the foreign filing deadline is 6 months from the priority date.
For utility patent applications, the foreign filing deadline is 1 year from the priority date. A PCT application extends the foreign filing deadline by an additional 18 months for a total of 30 months from the priority date. Of course, any patent protection for non-PCT countries must be filed within 12 months of the priority date. Here’s a timeline of foreign filing deadlines for utility patent applications.
