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 2-3, 17 are rejected under 35 U.S.C. 103 as being unpatentable over He in view of Song et al (US 20200264660; “Song” hereinafter). Regarding claim 2, He teaches the limitations of claim 1, but does not explicitly disclose: wherein the guide assembly includes a friction reducing structure for reducing friction generated by a relative movement of the rail receiving part with respect to the rail structure, and wherein the friction reducing structure includes at least one ball located between the rail receiving part and the rail structure. However, Song discloses: a rollable display device (100, fig. 1), comprising a first housing (101, fig. 3) and a second housing (102, fig. 3), sliding relative to each other (fig. 3), and a guide assembly (231, 232, fig. 17), the guide assembly comprising a rail receiving part (232, fig. 17) and a rail structure (231, fig. 17), wherein the guide assembly includes a friction reducing structure (2324) for reducing friction generated by a relative movement of the rail receiving part with respect to the rail structure (¶[0171]), and wherein the friction reducing structure includes at least one ball (“a member having a small friction force or a ball bearing”, ¶[0171], fig. 17) located between the rail receiving part and the rail structure (fig. 17). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to include Song’s friction reducing structure in He’s electronic device, in order to reduce friction between the first housing and the second housing, through a simple slide structure, so that conversion between a rolled state and an unrolled state is easily performed (¶[0024]). Regarding claim 3, He in view of Song discloses the limitations of claim 2, and Song further discloses: wherein the friction reducing structure includes a cage structure (2311, fig. 17) receiving the at least one ball (¶[0171]). Regarding claim 17, He teaches the limitations of claim 16, but does not explicitly disclose: wherein the guide assembly includes a friction reducing structure for reducing friction generated by a relative movement of the rail receiving part with respect to the rail structure, and wherein the friction reducing structure includes at least one ball and a cage structure receiving the at least one ball and disposed between the guide member and the rail structure. However, Song discloses: a rollable display device (100, fig. 1), comprising a first housing (101, fig. 3) and a second housing (102, fig. 3), sliding relative to each other (fig. 3), and a guide assembly (231, 232, fig. 17), the guide assembly comprising a rail receiving part (232, fig. 17) and a rail structure (231, fig. 17), wherein the guide assembly includes a friction reducing structure (2324) for reducing friction generated by a relative movement of the rail receiving part with respect to the rail structure (¶[0171]), and wherein the friction reducing structure includes at least one ball (“a member having a small friction force or a ball bearing”, ¶[0171], fig. 17) and a cage (2311, fig. 17) structure receiving the at least one ball (¶[0171]) disposed between the guide member and the rail structure (fig. 17). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to include Song’s friction reducing structure in He’s electronic device, in order to reduce friction between the first housing and the second housing, through a simple slide structure, so that conversion between a rolled state and an unrolled state is easily performed (¶[0024]). Claims 11 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over He in view of Kim et al (US 20240267444; “Kim” hereinafter). Regarding claim 11, He teaches the limitations of claim 1, but does not explicitly disclose: further comprising: a circuit board disposed on the first housing and connected to an antenna, wherein the second housing is electrically connected to the first housing and the circuit board through the guide assembly. However, Kim teaches: a circuit board (181 and 184, figs. 8B, ¶[0400]) disposed on a first housing (101, ¶[0349]) and connected to an antenna (¶[0310], [0349]), wherein a second housing (102) is electrically connected to the first housing and the circuit board (“a spring contact part 1060 may be formed on the front portion of the front metal part 102 to electrically connect the slide metal part 101 and the front metal part 102 in a spring contact manner”, ¶[0382], [0400]) through a guide assembly (1013b, 1014, 1015, figs. [0355]-[0356]). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to apply Kim’s teaching into He’s electronic device, such that a circuit board disposed on the first housing and connected to an antenna, wherein the second housing is electrically connected to the first housing and the circuit board through the guide assembly in order to reduce a difference in lengths of ground paths according to the relative movement so as to decrease a change in antenna performance of the plurality of antennas according to the relative movement, thereby overcoming an antenna design space limitation and securing antenna performance of a predetermined level or higher (¶[0017], [0034]). Regarding claim 19, He teaches the limitations of claim 16, but does not explicitly disclose: further comprising: wherein the electronic device further comprises a circuit board disposed on the first housing and connected to an antenna, and wherein the second housing is configured to be electrically connected to the first housing and the circuit board through the guide assembly. However, Kim teaches: wherein an electronic device (100, fig. 1) further comprises a circuit board (181 and 184, figs. 8B, ¶[0400]) disposed on a first housing (101, ¶[0349]) and connected to an antenna (¶[0310], [0349]), wherein a second housing (102) is electrically connected to the first housing and the circuit board (“a spring contact part 1060 may be formed on the front portion of the front metal part 102 to electrically connect the slide metal part 101 and the front metal part 102 in a spring contact manner”, ¶[0382], [0400]) through a guide assembly (1013b, 1014, 1015, figs. [0355]-[0356]). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to apply Kim’s teaching into He’s electronic device, such that a circuit board disposed on the first housing and connected to an antenna, wherein the second housing is electrically connected to the first housing and the circuit board through the guide assembly in order to reduce a difference in lengths of ground paths according to the relative movement so as to decrease a change in antenna performance of the plurality of antennas according to the relative movement, thereby overcoming an antenna design space limitation and securing antenna performance of a predetermined level or higher (¶[0017], [0034]). Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over He in view of Song et al (US 20210405703; “Song2” hereinafter). Regarding claim 15, He discloses the limitations of claim 1, and further teaches: a motor and transmission configured as a driving portion to drive the support structure to move (¶[0031], [0134]) He does not explicitly teach: a driving structure disposed in the housing and configured to move the second housing with respect to the first housing, wherein the driving structure includes: a motor configured to generate a driving force for a slide movement of the housing, a gear connected to the motor, and a rack configured to be engaged with the gear. However, Song2 teaches: a driving structure (500, fig. 4) disposed in a first housing (200a, fig. 4) and configured to move the second housing (200b, fig. 4) with respect to the first housing (¶[0346]), wherein the driving structure includes: a motor (510, fig. 4) configured to generate a driving force for a slide movement of the second housing (200b, fig. 4) with respect to the first housing (¶[0357]), a gear (520, fig. 4) connected to the motor (¶[0347]), and a rack (550, fig. 4) configured to be engaged with the gear (¶[0355]). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to replace He’s driving portion, with Song2’s driving structure into He’s first housing of the electronic device, in order to transmit power to the second housing, such that the second housing moves relative to the first housing (¶[0346]). 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 Song2. A person of ordinary skill in the art would have conceived the idea of creating such configuration. Therefore, the claimed subject matter would have been no more than a predictable combination of known techniques according to their respective purposes within routine skill and creativity (MPEP 2143). Allowable Subject Matter Claims 4, 6-8, 18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Regarding claim 4, the prior art of record taken alone or in combination, fails to teach or fairly suggest, in combination with other limitations recited in claims 1-3, a combination of limitations that: wherein the rail receiving part includes a second slit formed in the second surface and receiving at least a portion of the rail structure, wherein the rail structure includes a third end portion and a fourth end portion opposite to the third end portion, wherein the guide assembly includes a first rail cover connected to the third end portion and a second rail cover connected to the fourth end portion, and wherein the second rail cover is configured to reduce escape of the friction reducing structure from the second slit. None of the reference art of record discloses or renders obvious such a combination. Regarding claim 6, the prior art of record taken alone or in combination, fails to teach or fairly suggest, in combination with other limitations recited in claims 1 and 5, a combination of limitations that: wherein the first housing includes a frame connected to the rail receiving part and a first cover member connected to the first block cover and surrounding at least a portion of the frame and the rail receiving part. None of the reference art of record discloses or renders obvious such a combination. Claims 7-8 are objected to by virtue of dependency to claim 6. Regarding claim 18, the prior art of record taken alone or in combination, fails to teach or fairly suggest, in combination with other limitations recited in claim 16, a combination of limitations that: wherein the rail receiving part includes a first end portion and a second end portion opposite to the first end portion, wherein the guide assembly includes a first block cover connected to the first end portion and a second block cover connected to the second end portion and configured to reduce escape of the rail structure from the rail receiving part, and wherein the first housing includes a frame connected to the guide member and a first cover member connected to the first block cover and surrounding the frame and at least a portion of the guide member. None of the reference art of record discloses or renders obvious such a combination. Conclusion The prior art made of record and not relied upon is: US 11917777 A1 Electronic Device. This invention relates generally to a flexible display screen; a support plate, fixedly arranged corresponding to at least part of the flexible display screen; and an adjusting mechanism, for driving the support plate to support the flexible display screen in a first state and driving the support plate to support the flexible display screen in a second state.
