Abstract From the Canadian patent

The invention provides universal chloroplast integration and expression vectors which are competent to stably transform and integrate genes of interest into chloroplast genome of multiple species of plants. Transformed plants and their progeny are provided. Monocotyledonous and dicotyledonous plants are transformed which have never been transformed heretofore. Plants transformed with a synthetic gene express valuable biodegradable protein-based polymers (PBPs). Transformed plants produce high value molecules.

Why it's free to use

  • Filed August 5, 1998 and granted December 6, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 5, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 5, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
