In the composition described above compound A-1 fails to read on Chemical Formula 1 because compound A-1 of Shin, fails to include deuterium.
However, Fennimore teaches deuterated materials can be less susceptible to degradation by holes, electrons, or excitons. Have a greater processing tolerance, and can potentially improve device lifetime compared to their non-deuterated analogs (Fennimore, page 5, paragraph 098). Fennimore also teaches deuterated materials may be 10% to 100% deuterated (Fennimore, page 5, paragraph 097).
Therefore, it would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to deuterate compound A-1 of Shin such that it reads on Chemical Formula 1 of instant claim 1 and thereby reading on instant claim 14, to provide a compound useful as a host in the emission layer of the device of Shin, and less susceptible to degradation by holes, electron, or excitons, have a greater processing tolerance, and can potentially improve device lifetime, as taught by Fennimore.

Therefore, it would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to substitute second host compound B-99 in modified device Example 7 for compound C-4, as shown in device Example 9 of Shin, to arrive at the claimed composition of instant claim 16, because Shin teaches compound C-4 may suitably be selected as a second host in the light emitting layer of an organic optoelectronic device. The substitution would have been one preferred element for another and one of ordinary skill in the pertinent art would reasonably expect the predictable result that compound C-4 would be useful as a second host in the light emitting layer of modified device Example 7 and possess the benefits taught by Shin. See MPEP 2143.I.(B).
Modified device Example 7 as described above regarding claim 14, reads on instant claim 17 wherein the organic optoelectronic device comprises an anode and a cathode facing each other, and at least one organic layer between the anode and the cathode, wherein the at least one organic layer includes the compound for an organic optoelectronic device as claimed in instant claim 1.

Per claim 19, modified device Example 7 as described above regarding claim 14 reads on the organic optoelectronic device required by instant claim 19. However, Shin fails to teach a specific display device comprising the modified device Example 7.
Shin teaches that an embodiment of the invention provides a display device including an organic optoelectronic device (Shin, page 3).
Therefore, it would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to include modified device Example 7 in a display device, because one of ordinary skill in the art would have expected the elements of Shin in view of Fennimore to maintain their respective properties or functions after they have been combined, and this would have been combining prior art elements according to known methods to yield predictable results. See MPEP 2143.I.(A).
Modified device Example 7 as described above regarding claim 14, reads on instant claim 20 wherein the organic optoelectronic device comprises an anode and a cathode facing each other, and at least one organic layer between the anode and the cathode, wherein the at least one organic layer includes the composition for an organic optoelectronic device as claimed in instant claim 14.
Modified device Example 7 as described above regarding claim 20, reads on instant claim 21 wherein the at least one organic layer includes a light emitting layer, and the light emitting layer includes the composition for an organic optoelectronic device as claimed in instant claim 14.
Per claim 22, modified device Example 7 as described above regarding claim 14 reads on the organic optoelectronic device required by instant claim 22. However, Shin fails to teach a specific display device comprising the modified device Example 7.
Shin teaches that an embodiment of the invention provides a display device including an organic optoelectronic device (Shin, page 3).
Therefore, it would have been obvious to one of ordinary skill in the pertinent art before the effective filing date of the claimed invention to include modified device Example 7 in a display device, because one of ordinary skill in the art would have expected the elements of Shin in view of Fennimore to maintain their respective properties or functions after they have been combined, and this would have been combining prior art elements according to known methods to yield predictable results. See MPEP 2143.I.(A).
