How was Diversity Arrays (DArT) technology developed?
The Diversity Arrays or DArT technology was developed in CAMBIA laboratories, then funded by revenues from licensing the E.coli gusA gene for plant research. As with the GUS technology, CAMBIA committed to making the DArT technology widely available to all who will agree to maintain open access to the capability to use and improve it, regardless of ability to pay. Diversity Arrays were developed and patent claims were structured in order to provide a work-around to some of the many barriers to wide use of other types of genomic marker technology. Some of these barriers include high costs per marker and multiple patent rights owned by licensors who charge high fees or who do not make licenses available. The DArT technology, in contrast, has been made available through open source provisions in agreements available to everyone who agrees to share. Since publication, most of the patent applications have been abandoned in order to make all the data and uses available within the public doma
