Open the CIPO recordAbstract From the Canadian patent
DNA constructs comprise a DNA sequence homologous to some or all of the gene, encoded by the clone pTOM36. The constructs may further comprise a transcriptional initiation region operative in plants for transcribing this DNA sequence, optionally in the antisense direction to produce mRNA complementary to the pTOM36 gene. Transformed, plant cells and plants may be derived from such constructs: fruit from the plants (such as tomatoes) are expected to have modified ripening properties.

Why it's free to use
- Filed October 17, 1990 and granted January 30, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 17, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 17, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
