I am afraid that it is not possible to copy the chip, just like that.
http://www.factorypro.com/images/chip_1%20only_orig.JPG As you can see it is mounted on a PCB, with some components beneath, and I have also read elsewhere that it is not possible to copy the chip.
Of cause FactoryPro have made the chip, so that it is not possible to copy. Otherwise they had not sold as many...
