Patent Act Article 131: Formalities for Requesting a Trial
When requesting a trial against an examiner's decision of refusal, a trial for patent invalidation, a trial for invalidation of an extension of patent term, or a trial for correction, a written request for trial and the required fees must be submitted.
When making an amendment at the time of requesting a trial against an examiner's decision of refusal, submit a written amendment separately from the written request for trial. You must not include the content of the amendment within the written request for trial. A formal examination of the written request for trial will be conducted, and if there are no issues with the formalities, a duplicate will be served to the respondent.
In a request for a trial for invalidation, as the grounds for the request, you must (i) specifically identify the facts that serve as the basis for invalidating the patent, and (ii) describe the relationship with the evidence for each fact requiring proof. To summarize briefly, it looks something like: 'Claim 1 of Patent No. XXX lacks novelty. The reason is the description in paragraph XXX of Prior Art Document 1. Paragraph XXX of Prior Art Document 1 describes content equivalent to Claim 1 of Patent No. XXX.'
(Example of inappropriate grounds for request)
Patent No. XXX interferes with our business structure, so we request a trial decision to invalidate the patent.
