How should foreign priority claims be formatted in patent applications?

Foreign priority claims in patent applications should be formatted according to specific guidelines outlined in MPEP 214.04. The claim should include:

  • The application number of the foreign application
  • The country or intellectual property authority where the application was filed
  • The day, month, and year of filing

The MPEP states: ‘When the claim to priority concerns an application filed in a foreign country, the claim must identify the foreign country or intellectual property authority where the application was filed.’ This ensures proper identification and processing of the priority claim.
