The applicant must pay the examination fee before the start of the substantive examination upon request by the IPI and within the deadline set by the IPI.

• Novelty grace period

The disclosure of the invention does not disprove its novelty and is not considered part of the state of the art if the disclosure has been made within six months prior to the filing or priority date under one of the following circumstances:
- an evident abuse in relation to the applicant or his legal predecessor;
- the fact that the applicant or his legal predecessor has displayed the invention at an official or officially recognised international exhibition falling within the terms of the Convention on International Exhibitions of November 22, 1928, and he has declared the fact at the time of filing and has produced sufficient supporting evidence in due time.

• Grant, validity term and maintenance fees

When the examination procedure is successfully completed, the IPI shall register the patent in the Swiss Patent Register. After registration, the IPI shall publish a patent specification for a patent granted. The date of publication is the date of the grant. No grant and publication fees are required. The annual fees should be paid for each patent application or granted patent from the fourth year after the filing date. Patents are valid for 20 years from the filing date in Switzerland. Annuities should be paid annually on the last day of the month in which the patent application was filed. Patents in Switzerland may be renewed within six months after the due date by paying the surcharge.
