Such efforts are not required in situations of national emergency or other circumstances of extreme urgency or in cases of public non-commercial use.

⁴ The licence is primarily granted for supplying the domestic market. Article 40d remains reserved.

⁵ The proprietor of the patent has the right to appropriate remuneration. In assessing the remuneration, the circumstances of the individual case and the economic value of the licence are taken into account. In the case of a licence under Article 40d, the remuneration is determined by taking into account the economic value of the licence in the importing country, its level of development and the urgency in public health and humanitarian terms. The Federal Council shall specify the method of calculation.

⁶ The court shall decide on the grant and revocation of licences, on their scope and duration as well as on the remuneration payable. In particular, it shall revoke an entitled person's licence on request if the circumstances that led to its being granted no longer apply and it is not expected that they will arise again. Appropriate protection of the legal interests of the entitled person remains reserved. Where a licence is granted under Article 40d, legal remedies have no suspensive effect.
