It is not clear to me whether that is a provisional patent number, or a final number. In the link there is no date of issuing.
What is really unclear to me is how you can patent a loss of function mutation, when you did not discover the mutation. This article, published well before the patent filing date, makes no mention of any of the 3 patent authors.
I really hope this patent application was rejected.
The
sft mutant is
available from the Tomato Genetics Resource Center at UC Davis.
The mutant is listed as a spontaneous mutant.
