Allowable Subject Matter
Claims 6, 16, 22-23 and 26 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Claim 15, as well, if amended to be dependent from claim 22, would be objected to.
The following is a statement of reasons for the indication of allowable subject matter: the art is replete with iridium complexes as well as deuteration of these emitter compounds. However, given the specificity of each compound, it would require excessive hindsight to pick-and-choose the elements of each compound from the general disclosure of the closest prior art, Boudreault et al (US 20180097179 A1) and Su et al (US 20180097185 A1) and the references discussed above.
Regarding claim 6 and 26, the closest prior art is represented by the previously discussed references, none of which disclose the substituents of the claims, as well as Xia et al (US 20130299795 A1). Xia discloses ligands with cycloalkyl and deuterated alkyl groups together, but attached at different positions on the ligand, see below. It would require excessive hindsight without motivation to alter the substituent positions of Xia to arrive at the claims.
