Section 131. Priority Right. -
131.1.
An application for registration of a mark filed in the Philippines by a person referred to in Section 3, and who previously duly filed an application for registration of the same mark in one of those countries, shall be considered as filed as of the day the application was first filed in the foreign country.
131.2.
No registration of a mark in the Philippines by a person described in this section shall be granted until such mark has been registered in the country of origin of the applicant.
131.3.
Nothing in this section shall entitle the owner of a registration granted under this section to sue for acts committed prior to the date on which his mark was registered in this country: Provided, That, notwithstanding the foregoing, the owner of a well-known mark as defined in Section 123.1(e) of this Act, that is not registered in the Philippines, may, against an identical or confusingly similar mark, oppose its registration, or petition the cancellation of its registration or sue for unfair competition, without prejudice to availing himself of other remedies provided for under the law.
131.4.
In like manner and subject to the same conditions and requirements, the right provided in this section may be based upon a subsequent regularly filed application in the same foreign country: Provided, That any foreign application filed prior to such subsequent application has been withdrawn, abandoned, or otherwise disposed of, without having been laid open to public inspection and without leaving any rights outstanding, and has not served, nor thereafter shall serve, as a basis for claiming a right of priority.
