DEFINITION

Classification: 117/35

With a significant technique for (a) preliminary preparation or growth starting or (b) product handling or growth ending (e.g., arrangement of or crystallography of seed):

(under subclass 13) Subject matter in which a significant technique (i.e., a technique more than merely recited or provided for) is specified for: preparing the precursor* materials or the apparatus; handling the product (e.g., severing product from seed holder, manipulatively removing from furnace); initiating growth; or terminating growth (e.g., accelerated pulling motion).
