In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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 of this title, 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 20 is rejected under 35 U.S.C. 103 as being unpatentable over Yokote (US 20080198338 A1) in view of Li (CN 113376934 A).
Regarding claim 20, Yokote teaches control method of a projector (Fig. 1-11B), the method comprising: selecting a plurality of driving modes by a user ([0042]); driving a driving device (204, 303, 114) for moving a housing (101) based on a driving mode selected by the user among the plurality of driving modes (Fig. 4A and 4B); moving the housing (101) to a front surface of the projector (Fig. 1-11B) by the driving device (204, 303, 114); and projecting an image to a direction of a upper surface or a direction of a rear surface of the projector (Fig. 1-11B) in the front surface of the projector (Fig. 1-11B) by an optical engine (103, 105) provided on the housing (101; Fig. 4A and 4B) through a projection surface, wherein the plurality of driving modes comprises: a first mode (Fig. 2A, 2B, 4A, 7A, 7B) in which a lens of the optical engine (103, 105) is exposed to an outside of a main body (200) and the housing (101) of the projector (Fig. 1-11B) is moved to a direction of the front surface of the main body (200) by a first distance; and a second mode (Fig. 3A, 3B, 4B, 8A, 8B) in which the housing (101) of the projector (Fig. 1-11B) is moved to the direction of the front surface of the main body (200) by a second distance that is longer than the first distance.
Yokote does not explicitly teach the method further comprises: driving the driving device to move the housing completely inside of the main body of the projector and seal an inside of the main body with the optical engine and the projection surface inside of the main body of the projector.
Li teaches the method further comprises: driving the driving device (2) to move the housing (9) completely inside of the main body (1, 10, 11, 12, 100) of the projector (Fig. 2 and 8) and seal an inside of the main body (1, 10, 11, 12, 100) with the optical engine (3) and the projection surface (52) inside of the main body of the projector (Fig. 2-8).
It would have been obvious to a person of ordinary skills in the art at the time of the invention to combine Yokote with Li; because it improves the portability of the projection system when the system is not in operation.
Claims 1, 3-9 and 17-19 are rejected under 35 U.S.C. 103 as being unpatentable over Yokote in view of Perkins (US 20060072080 A1) and in further view of Li.
Regarding claim 1, Yokote teaches a projector (Fig. 1-11B) comprising: a main body (200); an optical engine (103, 105) configured to project an image; a housing (101) on which the optical engine (103, 105) is provided, the housing (101) being movable to an inside area of the main body (200) or to a front surface of the main body (200); a driving device (204, 303, 114) configured to move the housing (101; [0041], [0042], [0055]), wherein the optical engine (103, 105) further configured to project the image to at least one direction in the front surface of the main body (200) through a projection surface (106; Fig. 4A-4B).
Yokote does not explicitly teach a processor configured to control the driving device (204, 303, 114) based on an operation mode of the projector (Fig. 1-11B).
Perkins teaches processor (62, 64) configured to control the driving device (50) based on an operation mode of the projector ([0034]-[0035]).
It would have been obvious to a person of ordinary skills in the art at the time of the invention to combine Yokote with Perkins; because it allows automating the movement of the drive mechanism as suggested by Yokote ([0041], [0042]).
Neither Yokote nor Perkins specifically teaches the housing configured to be moved completely into the inside area of the main body and seal the inside area of the main body of the projector with the optical engine and the projection surface sealed inside of the main body of the projector.
Li teaches the housing (9) configured to be moved completely into the inside area of the main body (1, 10, 11, 12, 100) of the projector (Fig. 2 and 8) and seal the inside area of the main body (1, 10, 11, 12, 100) with the optical engine (3) and the projection surface (52) sealed inside of the main body of the projector (Fig. 2-8).
It would have been obvious to a person of ordinary skills in the art at the time of the invention to combine Yokote and Perkins with Li; because it improves the portability of the projection system when the system is not in operation.
Regarding claim 3, Yokote further teaches the at least one direction corresponds to a direction of an upper surface of the main body (200) or to a direction of a rear surface of the main body (200; Fig. 4A-4B).

Regarding claim 5, the combination of Yokote, Perkins, and Li consequently results in the processor (62, 64 of Perkins) further configured to adjust a layout of the image based on a location of the optical engine (103, 105 of Yokote), the location of the optical engine (103, 105; [0060]-[0061] of Yokote) being controlled by the processor (62, 64 of Perkins).
Regarding claim 6, the combination of Yokote, Perkins, and Li consequently results in the processor (62, 64 of Perkins) further configured to control the driving device (204, 303, 114 of Yokote) to locate the optical engine (103, 105 of Yokote) in a location corresponding to a screen ratio of the image ([0030], [0041], [0042] of Yokote).
Regarding claim 7, the combination of Yokote, Perkins, and Li consequently results in the processor (62, 64 of Perkins) further configured to control the driving device (204, 303, 114 of Yokote) to located the optical engine (103, 105 of Yokote) in a location designated by a user ([0030], [0041], [0042] of Yokote).
Regarding claim 8, Yokote further teaches the main body (200) further comprises a main groove (203) configured to guide the housing (101) being movable to the front surface of the main body (200), wherein a horizontal width of the front surface of the housing (101) is substantially identical or identical to a horizontal width of the main groove (203; Fig. 1A-3B).
The combination of Yokote, Perkins, and Li consequently results in, based on the housing (9 of Li) being placed in the inside area of the main body (1, 10, 11, 12, 100 of Li), a front surface of the housing (9 of Li) is formed in an identical shape to the front surface of the main body (1, 10, 11, 12, 100 of Li), and the front surface of the main body (1, 10, 11, 12, 100 of Li) and the front surface of the housing (9 of Li) are connected so as to seal the inside area of the main body (1, 10, 11, 12, 100 of Li; Fig. 2-8).
Regarding claim 9, the combination of Yokote, Perkins and Li consequently results in based on the housing (9 of Li) being sealed in the inside area of the main body (1, 10, 11, 12, 100 of Li) and a vertical length of the front surface of the housing (9 of Li) is substantially identical or identical to a vertical length of the front surface of the main body (1, 10, 11, 12, 100; Fig. 2 and 8 of Li).
Regarding claim 17, Yokote further teaches the main body (200) comprises a groove (203) configured to guide the housing (101) to move linearly, wherein the housing (101) further comprises a guide rail (107) formed along a longitudinal direction of the housing (101) on a lower surface of the housing (101).
Yokote does not teach explicitly the main body (200) comprises a guide rail and the housing (101) further comprises a groove.
Having the main body (200) comprising a guide rail and the housing (101) further comprising a groove amounts to rearrangement of parts that does not change the principle of operation in any way.
Rearrangement of parts without changing the operation of the reference device is prima facie. In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950).
Regarding claim 18, Yokote further teaches main body (200) further comprises a first groove (203) formed on a side surface of main body (200), and wherein the driving device (204, 303, 114) comprises: a first motor (204) placed in the first groove (203) and configured to drive the housing (101; [0041], [0042], [0055]); a first gear (301) connected to a driving axis of the first motor (204); and a first rack gear (108) engaged with the first gear (301), the first rack gear (108) being formed along a moving direction of the housing (101).
