Article 108
Licence due to failure to exploit invention
1 - After the time limits referred to in Article 106(2) have expired, a patentee who, without a good reason or legal basis, does not exploit an invention, directly or under licence, or does not do so in such a way as to meet national needs, may be obliged to grant a licence for its exploitation.
2 - A patentee may also be obliged to grant an exploitation licence for an invention if he ceases to exploit it for three consecutive years without a good reason or legal basis.
3 - Objective technical or legal reasons beyond the patentee's control and irrespective of his situation making the exploitation of the invention impossible or insufficient are considered good reason, but not economic or financial difficulties.
4 - For as long as a compulsory licence remains in force, the patentee may not be obliged to grant another before the previous one is cancelled.
5 - A compulsory licence may be cancelled if the licensee does not exploit the invention in such a way as to meet national needs.
Article 109
Dependent licences
1) If it is not possible to exploit a patented invention, without prejudice to the rights conferred by a previous patent, and the two inventions are used for different industrial purposes, a licence may only be granted if the first invention is essential to the exploitation of the second, and only in the part necessary for said exploitation, and the holder of the first patent is entitled to fair compensation.
2) If inventions protected by dependent patents serve the same industrial purpose and a compulsory licence is to be granted, the previous patentee may also demand a compulsory licence for the previous patent.
3) If an invention concerns a process for preparing a chemical, pharmaceutical or food product protected by a current patent, and whenever this process patent represents notable technical progress in relation to the previous patent, both the holder of the process patent and the holder of the product patent are entitled to demand a compulsory licence for the other holder's patent.
4) If the obtainer of a plant variety cannot obtain or exploit a plant securing right without infringing a prior patent, he may request a compulsory licence for nonexclusive exploitation of the invention protected by the patent, provided that this licence is necessary for the exploitation of the same plant variety, on payment of appropriate remuneration.
5) Whenever a licence of the type provided for in the previous paragraph is granted, the patentee is entitled to a reciprocal licence on reasonable terms to use the protected variety.
6) If the holder of a patent for a biotechnological invention is unable to exploit it without infringing a previous plant variety securing right, he may request a compulsory licence for non-exclusive exploitation of the variety protected by the securing right on payment of an appropriate sum.
7) Whenever a licence of the type provided for in the previous paragraph is granted, the holder of the securing right is entitled to a reciprocal licence on reasonable terms to use the protected invention.
8) Applicants for the licences referred to in paragraphs 4 and 6 must prove that:
a) They approached the patentee or plant securing right holder in vain to obtain a contractual licence;
b) The plant variety or invention represents important technical progress of considerable economic interest in relation to the invention claimed in the patent or to the plant variety being protected.
9 - This article also applies whenever one of the inventions is protected by a patent and the other by a utility model.
Article 110
Public Interest
1) A patentee may, in the public interest, be obliged to grant a licence for the exploitation of his invention.
2 ) There are considered to be reasons of public interest if the start, increase or generalisation of the exploitation of the invention, or an improvement in the conditions of its exploitation, is of vital importance to public health or national defence.
3) There are also considered to be reasons of public interest if failure to exploit or insufficient quality or quantity of exploitation is highly detrimental to the country's economic or technological development.
4) The government shall be responsible for granting a licence in the public interest.
