Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
Claims 2, 4, 12, 14, are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 2 and 12 recite the limitation “wherein the second pixel comprises the first light-emitting device, the first light-recording device”. It is unclear what this limitation means because the first pixel already comprises the first light-emitting device and first light-recording device (see claims 1 and 11). Therefore, the claim has an indefinite scope. For the purpose of examination, this limitation will be read as: “wherein the second pixel comprises another first light-emitting device, another first light-recording device”
Claims 4 and 14 recite the limitation “wherein the second light-emitting device comprises the first light-emitting unit”. It is unclear what this limitation means because the first light-emitting device already comprises the first-light emitting unit (see claims 4 and 14). Therefore, the claim has an indefinite scope. For the purpose of examination, this limitation will be read as: “wherein the second light-emitting device comprises another first light-emitting unit”
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
