Section 8 - The application shall contain a description of the invention, together with drawings where necessary, and a precise statement of the subject matter for which patent protection is sought (one or more claims). The fact that the invention relates to a chemical compound shall not mean that a specific use must be disclosed in the claim. The description shall be sufficiently clear to enable a person skilled in the art, with the guidance thereof, to carry out the invention. An invention relating to a biological material or involving the use of biological material when being carried out shall be regarded, in the cases referred to in section 8a, as disclosed with sufficient clarity only if the requirements set out in that section are also satisfied. (30.6.2000/650)
Section 8 a - Where an invention concerns biological material or the carrying out thereof involves the use of a biological material which neither is available to the public nor can be described in the application documents in such a manner as to enable a person skilled in the art to carry out the invention, a sample of the biological material shall be deposited no later than on the date the application was filed. The biological material shall be continuously on deposit thereafter so that any person entitled under this Act to a sample of the deposited material may have the sample furnished in Finland. The Government shall decree where deposits may be made.
If a deposited biological material ceases to be viable or if samples of the material cannot be furnished for other reasons, it may be replaced by a new deposit of the same biological material, as decreed by the Government. Once this has been done, the new deposit shall be deemed to have been made on the date of the previous deposit.

Section 52 - The court shall declare a patent invalid, in a relevant action:
