(1) The human body, at the various stages of its formation and development, including germ cells, and the simple discovery of one of its elements, including the sequence or partial sequence of a gene, cannot constitute patentable inventions.
(2) An element isolated from the human body or otherwise produced by means of a technical process, including the sequence or partial sequence of a gene, may constitute a patentable invention even if the structure of that element is identical to the structure of a natural element.
(3) The industrial application of a sequence or partial sequence of a gene must be disclosed in the application specifying the function performed by the sequence or partial sequence.
(4) If the invention concerns a sequence or partial sequence of a gene whose structure corresponds to that of a natural sequence or partial sequence of a human gene, the patent claim is to include its use for which industrial application is disclosed pursuant to subsection (3).
