Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a method for producing a transgenic plant in which a transforming agent such as a recombinant Agrobacterium or an isolated DNA molecule capable of conferring a desired phenotypic trait is injected into plant tissues using aneedleless injection device. A preferred embodiment of the method provides the precise delivery of the transforming agent to floral tissues of a plant, allowing the direct insertion of the DNA of the transforming agent into germline cells of the plant that develop into seeds. This embodiment provides a more efficient method of transformation and subsequent regeneration of a transgenic plant.

Why it's free to use
- Filed October 19, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 19, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 19, 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.
