Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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. Claims 1-3, 6-9, 11-15, 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Buechin et al (US 20200121045; “Buechin” hereinafter) in view of Lee et al (US 6392639; “Lee” hereinafter). Regarding claim 1, Buechin teaches: a protective case for an electronic device, comprising: a front cover (102, fig. 7); a rear cover (104, fig. 7) including a first sidewall (see annotated fig. 7 below), a second sidewall (see annotated fig. 7 below) aligned at an angle relative to the first sidewall (fig. 7), wherein the second sidewall is configured to releasably retain the electronic device (¶[0054]), and; a hinge (106, fig. 1), operatively connecting the front cover to the rear cover (¶[0051]), defining a hinge axis (see annotated fig. 1 below), wherein the front cover is movable, relative to the rear cover and about the hinge axis (¶[0051]), between a closed position (fig. 5) and an open position (fig. 4). PNG media_image1.png 367 574 media_image1.png Greyscale PNG media_image2.png 437 634 media_image2.png Greyscale Buechin does not explicitly teach: a storage compartment positioned adjacent to the first sidewall, wherein the storage compartment is configured to detachably store a stylus associated with the electronic device. However, Lee teaches: A cover (60, fig. 3) comprising a first sidewall (66, fig. 3) defining a storage compartment (as disclosed upon examination of figures, 5A and 6A) configured to detachably store a stylus (90) associated with an electronic device (40, fig. 3). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to apply Lee’s teaching and move the first sidewall of Buechin away from the hinge, in order to create a storage compartment positioned between the hinge and the first sidewall, for the advantage of detachably storing a stylus associated with the electronic device. The claim would have been obvious because the particular known technique was recognized as part of the ordinary capabilities of one skilled in the art, as evidenced by Lee. Therefore, the claimed subject matter would have been no more than a predictable combination of a plurality of known techniques according to their respective purposes within routine skill and creativity (§MPEP 2143). Regarding claim 2, Buechin in view of Lee teaches the limitations of claim 1, and the combination further teaches: wherein the storage compartment includes a surface (see annotated fig. 6C from Lee below, and ¶[0055], Buechin) that transitions into the first sidewall. PNG media_image3.png 623 621 media_image3.png Greyscale Regarding claim 3, Buechin in view of Lee teaches the limitations of claim 1, and the combination further teaches: wherein the first sidewall is a partial sidewall that defines a gap between the first sidewall and the second sidewall (see annotated fig. 3 below from Lee).

Regarding claim 7, Buechin in view of Lee teaches the limitations of claim 6, and Buechin further teaches: wherein the first portion defines recesses (628, fig. 6) configured to receive buttons of the electronic device (¶[0057]). Regarding claim 8, Buechin in view of Lee teaches the limitations of claim 1, and Buechin further teaches: wherein the first sidewall, the second sidewall, and the storage compartment are formed as a single molded component (the modified rear cover would meet this limitation, ¶[0055], Buechin). Regarding claim 9, Buechin in view of Lee teaches the limitations of claim 1, and Buechin further teaches: wherein the rear cover includes a curved peripheral edge portion (see annotated fig. 7 below). PNG media_image5.png 358 489 media_image5.png Greyscale Regarding claim 11, Buechin in view of Lee teaches the limitations of claim 1, and Buechin further teaches: wherein the storage compartment is positioned between the hinge and the first sidewall when the front cover is in the open position (via the combination of Lee into Buechin, in claim 1). Regarding claim 12, Buechin in view of Lee teaches the limitations of claim 1, and Buechin further teaches: wherein the hinge at least partially surrounds the storage compartment when the front cover is in the closed position (via the combination of Lee into Buechin, in claim 1, fig. 5, Buechin). Regarding claim 13, Buechin teaches: a system, comprising: an electronic device (624, ¶[0050]); and a protective case (100), the protective case including: a front cover (102, fig. 7); a rear cover (104, fig. 7) including a first sidewall (see annotated fig. 7 above for claim 1), a second sidewall (see annotated fig. 7 above for claim 1) aligned at an angle relative to the first sidewall (fig. 7), wherein the second sidewall is configured to releasably retain the electronic device (¶[0054]), and; a hinge (106, fig. 1), operatively connecting the front cover to the rear cover (¶[0051]), defining a hinge axis (see annotated fig. 1 above for claim 1), wherein the front cover is movable, relative to the rear cover and about the hinge axis (¶[0051]), between a closed position (fig. 5) and an open position (fig. 4). Buechin does not explicitly teach: a storage compartment positioned adjacent to the first sidewall, wherein the storage compartment is configured to detachably store a stylus associated with the electronic device. However, Lee teaches: A cover (60, fig. 3) comprising a first sidewall (66, fig. 3) defining a storage compartment (as disclosed upon examination of figures, 5A and 6A) configured to detachably store a stylus (90) associated with an electronic device (40, fig. 3). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to apply Lee’s teaching and move the first sidewall of Buechin away from the hinge, in order to create a storage compartment positioned between the hinge and the first sidewall, for the advantage of detachably storing a stylus associated with the electronic device. The claim would have been obvious because the particular known technique was recognized as part of the ordinary capabilities of one skilled in the art, as evidenced by Lee. Therefore, the claimed subject matter would have been no more than a predictable combination of a plurality of known techniques according to their respective purposes within routine skill and creativity (§MPEP 2143). Regarding claim 14, Buechin in view of Lee teaches the limitations of claim 13, and the combination further teaches: wherein the storage compartment includes a surface (see annotated fig. 6C from Lee above for claim 2, and ¶[0055], Buechin) that transitions into the first sidewall. Regarding claim 15, Buechin in view of Lee teaches the limitations of claim 13, and the combination further teaches: wherein the first sidewall is a partial sidewall that defines a gap between the first sidewall and the second sidewall (see annotated fig. 3 below from Lee).
