Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 10 is rejected under 35 U.S.C. 103 as being unpatentable over Mohammed. Regarding Claim 10. The device of claim 9, Mohammed (Fig.1C) discloses further comprising an electrode layer (155) between the first doped semiconductor layer (p-layer 298) and the insulating layer (112/116) and in contact with the first doped semiconductor layer (p-layer 298), wherein the electrode layer is substantially transparent. Mohammed (Fig.1C) does not particularly disclose wherein the electrode layer is substantially transparent. Mohammed ([0034]) discloses that there is another electrode (170) on top of the device which is transparent and it discloses that this transparent electrode enhances the current spreading and therefore better light emission. Therefore, it would have been obvious in the art before the effective filing of the application to have the electrode as a transparent electrode to enhance the current spreading and therefore better light emission. Claim(s) 3-6 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Mohammed in view of Schiaffino et al. (US 2008/0096297; hereinafter Schiaffino). Regarding Claim 3. The device of claim 1, Mohammed (Fig.1C) discloses wherein the plurality of edge contacts (160/170) are along one side but it does not particularly disclose wherein the edge contacts are partially along two sides adjacent the one side of the second doped semiconductor layer.

Therefore, it would have been obvious in the art before the effective filing of the application to have edge contacts along all sides continuously resulting in good lateral spreading of current in electrical contacts and improved device characteristics. Regarding Claim 4. The device of claim 3, Schiaffino (Fig.1, Fig.3) discloses wherein the plurality of edge contacts (108/110/122/124; Fig.1; [0049]) are along one side and completely along two sides adjacent the one side of the second doped semiconductor layer (106; Fig.2).

Therefore, it would have been obvious in the art before the effective filing of the application to have edge contacts along all sides continuously resulting in good lateral spreading of current in electrical contacts and improved device characteristics. Regarding Claim 6. The device of claim 1, Mohammed (Fig.1C) discloses wherein the plurality of edge contacts (160/170) are along one side but it does not particularly disclose wherein the edge contacts are along a second opposing side of the second doped semiconductor layer.

Therefore, it would have been obvious in the art before the effective filing of the application to have edge contacts along all sides continuously resulting in good lateral spreading of current in electrical contacts and improved device characteristics. Regarding Claim 19. The device of claim 17, Mohammed (Fig.1C) discloses wherein the plurality of edge contacts (160/170) are along one side but it does not particularly disclose wherein the edge contacts are partially along two sides adjacent the one side of the second doped semiconductor layer. Schiaffino (Fig.1, Fig.3) in a related art discloses a light emitting device having edge contacts (108/110/122/124; Fig.1; [0049]) along one side and partially along two sides adjacent the one side of the second doped semiconductor layer (it shows along other sides too). Therefore, it would have been obvious in the art before the effective filing of the application to have edge contacts along all sides continuously resulting in good lateral spreading of current in electrical contacts and improved device characteristics. Regarding Claim 20.
