Cosa ha detto la corte suprema canadese (sentenza) ?
"The court heard the question of whether intentionally growing genetically modified plants constitutes "use" of the patented invention of genetically modified plant cells. By a 5-4 majority, the court ruled that it does."
"Canada has a sui generis system of protection for plants. The Plant Breeders’ Rights Act, S.C. 1990, c. 20,represents a nuanced statutory regime that takes into consideration the rights of both the developers of new plant varieties and users. There is nothing in the Plant Breeders’ Rights Act that would exclude genetically modified new plant varieties, such as Roundup Ready Canola, from its purview."
