How are inventor details handled in international patent applications?

The handling of inventor details in international patent applications depends on the requirements of the designated states:

• If the inventor is not the applicant, information about the inventor must be provided in the Request if required by the national law of at least one designated state.
• Most countries require inventor information for the national phase.
• When the inventor is not the applicant, the “inventor only” check-box should be marked, and the inventor’s name and address should be indicated in Box No. III of the application form.

The MPEP states: Where the inventor is not the applicant, indications concerning the inventor must nevertheless be made in the Request where the national law of at least one of the designated States requires that the name of the inventor be furnished at the time of filing a national application ( PCT Rule 4.1(a)(iv) ).
