Therefore, in view of Barton, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the housing of Bian by adding a second housing portion and adding a second light strip coupled to the second housing portion, in order to adjust the light illumination range. Claim 14: Bian teaches a light assembly configured to be coupled to a vehicle hood, the light assembly comprising: a housing (101, fig. 1I); a first hood mount (103, fig. 1A) extending from the housing and a second hood mount (105, fig. 1A) extending from the housing, the first hood mount (103) and the second hood mount (105) each including an arm (102, 104, fig. 1A), and a grip (103, 105, fig. 1A) coupled to a distal end of the arm (see fig. 1A) and configured to engage the vehicle hood (hooked on the underside of the hood, see para [0044]); a battery pack receiver (108, fig. 1A) coupled to the housing, the battery pack receiver (108) configured to removably receive a rechargeable battery pack (removable battery pack, see para [0054]); and a light source (106, 120, fig. 1A) coupled to the housing (101) and configured to generate light. However, Bian fails to teach the housing having a first housing portion and a second housing portion slidable relative to the first housing portion to change an overall length of the housing, the first hood mount extending from the first housing portion and the second hood mount extending from the second housing portion. Barton teaches a housing (5, 10, fig. 1) having a first housing portion (5, fig. 1) and a second housing portion (10, fig. 1) slidable relative to the first housing portion to change an overall length of the housing (see abstract). Therefore, in view of Barton, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the housing of Bian where the housing includes a first housing portion and a second housing portion slidable relative to the first housing portion to change an overall length of the housing where the first hood mount extending from the first housing portion and the second hood mount extending from the second housing portion, in order to adjust the light illumination range. Claim 15: Bian teaches the housing (101, fig. 1A) includes a rail (rail of 113, fig. 1I). However, Bian fails to teach the rail coupled to the first housing portion and received by the second housing portion, and wherein the second housing portion is slidable along the rail. Barton teaches a rail (15, fig. 1) coupled to the first housing portion (5, fig. 1) and received by the second housing portion (10, fig. 1), and wherein the second housing portion (10) is slidable along the rail (15) (see Col. 3 lines 44-47). Therefore, in view of Barton, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the housing of Bian where the housing includes a first housing portion and a second housing portion slidable relative to the first housing portion to change an overall length of the housing where the rail is coupled to the first housing portion and received by the second housing portion, and wherein the second housing portion is slidable along the rail, in order to adjust the light illumination range. Claim 16: Bian teaches the light source includes a first light strip (106, fig. 1A) coupled to the first housing portion (101) and However, Bian fails to teach a second light strip coupled to the second housing portion. Barton teaches a light source (1, fig. 1) includes a first light strip (left 1) coupled to the first housing portion (5, fig. 1) and a second light strip (right 1, fig. 1) coupled to the second housing portion (10, fig. 1). Therefore, in view of Barton, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the housing of Bian by adding a second housing portion and adding a second light strip coupled to the second housing portion, in order to adjust the light illumination range. Claim(s) 11 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bian (US 2018/0231193) in view of Gu et al. (US 2011/0141737) (hereinafter Gu). Claim 11: Bian fails to teach the second light housing portion is pivotable relative to the first light housing portion about a third pivot axis and a fourth pivot axis that is perpendicular to the third pivot axis. Gu teaches a second light housing portion (10, fig. 1) is pivotable relative to the first light housing portion (12, 13, fig. 1) about a third pivot axis (vertical axis of 60, fig. 3) and a fourth pivot axis (horizontal axis of 50, fig. 3) that is perpendicular to the third pivot axis. Therefore, in view of Gu, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the second light housing of Bian by making the second light housing portion pivotable relative to the first light housing portion about a third pivot axis and a fourth pivot axis that is perpendicular to the third pivot axis, in order to add another degree of range of motion. Claim 20: Bian teaches wherein the light housing (101) includes a first light housing portion (101) coupled to the battery pack receiver (108) and a second light housing portion (top portion of 120, fig. 2B) pivotally coupled to the first light housing portion (see fig. 2B), wherein the light source (120) is supported in the second light housing portion (see fig. 2B). However, Gu fails to teach the second light housing portion is pivotable relative the first light housing portion about a third axis and a fourth axis that is perpendicular to the third axis. Gu teaches a second light housing portion (10, fig. 1) is pivotable relative to the first light housing portion (12, 13, fig. 1) about a third pivot axis (vertical axis of 60, fig. 3) and a fourth pivot axis (horizontal axis of 50, fig. 3) that is perpendicular to the third pivot axis. Therefore, in view of Gu, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the second light housing of Bian by making the second light housing portion pivotable relative to the first light housing portion about a third pivot axis and a fourth pivot axis that is perpendicular to the third pivot axis, in order to add another degree of range of motion.
