1. If a Party requires, as a condition for authorising the marketing of pharmaceutical products that utilise new chemical entities (referred to as “authorisation” in this Article) the submission of undisclosed test or other data necessary to determine whether the use of those products is safe and effective, the Party shall protect such data against disclosure, if the origination of such data involves considerable effort, except where the disclosure is necessary to protect the public or unless steps are taken to ensure that the data are protected against unfair commercial use.  

2. Each Party shall provide that for data subject to paragraph 1 that are submitted to the Party after the date of entry into force of this Agreement:  
     (a) no person other than the person who submitted them may, without the latter’s permission, rely on such data in support of an application for an authorisation during a period of not less than six years from the date on which the Party granted authorisation to the person that produced the data for authorisation; and  
     (b) a Party shall not grant an authorisation to any person who relies on such data during a period of not less than eight years from the date on which the Party granted the authorisation to the person that produced the data for the authorisation, unless the person that produced these data provides permission.

Subject to this paragraph, there shall be no limitation on either Party to implement abbreviated authorisation procedures for such products on the basis of bioequivalence and bioavailability studies.
