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) 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 20160093828 A1) (Kim, hereafter) in view of Li et al. (US 11581507 B2)( Li, hereafter).
Regarding claims 1, Kim discloses (Figure 2 and corresponding text)a display panel (100), comprising: a light-emitting device (120); and an encapsulating member (130) disposed on the light-emitting device (120) for encapsulating the light-emitting device (120), the encapsulating member comprising a first inorganic encapsulating layer (130), the first inorganic encapsulating layer (130)comprising at least a first inorganic encapsulating sub-layer(131), a second inorganic encapsulating sub-layer(132), and a third inorganic encapsulating(133) sub-layer that are sequentially stacked (π48) in a direction away from the light-emitting device (120); a refractive index of the first inorganic encapsulating sub-layer is n1, a refractive index of the second inorganic encapsulating sub-layer is n2, and a refractive index of the third inorganic encapsulating sub-layer is n3, wherein n2<n3<n1 (π59) and n1−n2>0.4 (π54). Kim fails to explicitly disclose wherein thickness of the third inorganic encapsulating sub-layer is greater than a thickness of the first inorganic encapsulating sub-layer and a thickness of the second inorganic encapsulating sub-layer;
Li discloses (Figures 2 and 3) wherein a thickness of the third inorganic encapsulating sub-layer (1203)(500 to 60nm) layer is greater than a thickness of the first inorganic encapsulating sub-layer (1201) (200 to 300nm) and a thickness of the second inorganic encapsulating sub-layer (1202) (360-400 nm) (Column 5, lines 1-20).
Therefore it would have been obvious to one of ordinary skill before the effective filing date to modify wherein a thickness of the third inorganic encapsulating sub-layer is greater than a thickness of the first inorganic encapsulating sub-layer and a thickness of the second inorganic encapsulating sub-layer the motivation being a controlled thickness leads to compactness of the device without sacrificing luminous efficiency.
Regarding claims 2, Kim discloses wherein n1>1.9. (π16),
Regarding claims 3 and 4, Kim as modified by Li fails to explicitly disclose wherein n3>1.7 (claim 3); wherein n2<1.5 (claim 4).
It would have been obvious to one of ordinary skills in the art before the effective filing date to further modify the display device of Kim wherein n3>1.7 or wherein n2<1.5, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art. In re Aller, 105 USPQ 233.
