Specific Patent Information

Patent Number

Title, Independent Claims and Summary of Claims

Assignee

US 5376543

  • Earliest priority - 21 December 1987
  • Filed - 7 December 1992
  • Granted - 27 December 1994
  • Expired - 29 January 2003

Title - Agrobacterium mediated transformation of germinating plant seeds

Claim 1

A non-tissue culture process for producing a transgenic soybean plant, which process comprises:

A) germinating a seed of a Glycine max plant for about 24 to 48 hours;
B) inoculating the meristematic or mesocotyl cells produced by the germinating seed of step (A), prior to differentiation of said cells, with an armed or disarmed Agrobacterium strain containing an Agrobacterium-derived vector, said vector containing a transferable gene; and
C) allowing the cells to differentiate into a mature plant.

Granted US 5376543 has expired due to non-payment of maintenance fees as reported by USPTO.

Production of a transgenic soybean plant through a non-tissue culture process. Meristematic or mesocotyl cells are inoculated with an armed or disarmed Agrobacterium vector having a gene of interest. The cells differentiate into a mature plant.


University of Toledo

AU 648951 B2

  • Earliest priority - 21 December 1987
  • Filed - 27 April 1993
  • Granted - 5 May 1994
  • Expired - 18 July 2002

Title - Agrobacterium mediated transformation of germinating plant seeds

Claim 1

A non-tissue culture process for producing a transgenic plant, which process comprises:

A) germinating a seed of a Glycine max plant for about 24 to 48 hours;
B) inoculating the meristematic or mesocotyl cells produced by the germinating seed of step (A), prior to differentiation of said cells, with an armed or disarmed Agrobacterium strain containing an Agrobacterium-derived vector, said vector containing a transferable gene; and
C) allowing the cells to differentiate into a mature plant.

Granted AU 648951 recites the same process of producing a transgenic soybean plant in claim 1 as that of US 5376543 (see above).

EP 397687 B1

  • Earliest priority - 21 December 1987
  • Filed - 16 December 1988
  • Granted - 11 May 1994
  • Expected expiry - 16 December 2008

Title - Agrobacterium mediated transformation of germinating plant seeds

Claim 1

A non-tissue culture process for producing a transgenic plant, which comprises:

A) germinating a seed of a Phaseolus vulgaris or a Glycine max plant for 24 to 48 hours;
B) inoculating the meristematic or mesocotyl cells produced during germination, prior to differentiation of the seed, with a virulent or non-virulent Agrobacterium strain containing a transferable gene in an Agrobacterium -derived vector; and
C) allowing the cells to differentiate into a mature plant.

Granted EP 397687 is a national phase entry of WO 1989/05859.

Designated contracting States at the time of grant are: Austria (patent lapsed as reported by INPADOC), Belgium (patent lapsed as reported by INPADOC), Switzerland (patent lapsed as reported by INPADOC), Germany (patent lapsed as reported by INPADOC), France (patent lapsed as reported by INPADOC), United Kingdom (patent lapsed as reported by INPADOC), Italy, Liechtenstein, Luxembourg, Netherlands (patent lapsed as reported by INPADOC), Sweden (patent lapsed as reported by INPADOC).

The method for producing a transgenic soybean plant is the same as the one disclosed in the related United States and Australian patents (above mentioned), but transformation of beans (Phaseolus vulgaris) is also included in the claims (see section on beans).

Remarks

  1. National phase entry of WO 1989/05859 in Japan (JP H04/501201) is deemed to be withdrawn.
  2. Other national phase entries of WO 1989/05859 include Denmark (DK 126690) and Kuwait (KR 154872).
