Taiwan: TIPO provides remarks on time limits in invalidation proceedings

Yen-Bin Gu of Saint Island Intellectual Property Group explains how TIPO has reacted to the regulations introduced to counter lengthy invalidation actions

Under the old Patent Act, a supplementary invalidation brief, evidence, a counter-statement, and/or amendment of claims could be filed at any time before Taiwan’s Intellectual Property Office (TIPO) issued a decision.

In order to prevent an invalidation action from dragging on for too long, TIPO has included a rigid timeframe in the new Patent Act that was implemented and enforced since last year. 

After taking stock of the situation brought about by the stringent time-constraint requirement over a year, TIPO has provided some remarks: 

1. The new stipulation that an invalidation petitioner must submit supplementary briefs and/or evidence within three months from the date that the invalidation action is filed, or within one month from the receipt of any notification from TIPO, has been and will be strictly observed. In this context, any supplementary evidential materials that are filed late would not be taken into account except if they are filed at the request of the responsible examiner to clarify the circumstances of the case.

2. Filing amendment of claims in an invalidation action is also restricted. The patentee is only allowed to conduct an amendment before a deadline designated by the examiner for submitting a counter-statement, a supplementary counter-statement or upon receipt of a notification from TIPO that there are lingering doubts to be cleared, or that the amendment filed with the counter-statement has been rejected. No time limit is imposed on the patentee only if the patent at issue is the subject of a merit lawsuit.

3. In the case that a counter-statement against an invalidation action is filed along with an amendment after a designated deadline, the contents of the counter-statement, filed prior to finalisation of the invalidation action, are to be considered. As to the amendment, it will be rejected for not being filed at an appropriate time as specified above. However, since the contents of the counter-statement filed by the patentee are drafted based on the amendment concurrently filed, the examiner will generally notify the patentee that the amendment not timely filed is rejected and the case will be examined based upon the granted claims as published. Upon receipt of such notification, the patentee may re-file the amendment and the examiner will examine it with cross-reference to the contents of the counter-statement as filed.

In view of the time limits prescribed in the Patent Act, either the invalidation petitioner or the patentee is placed under tight time pressure. It would be of much help if practitioners could assist their clients to collect useful evidential materials and develop winning strategies in the first place.
