Office Action

§112
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 . DETAILED ACTION This office action is in regards to application # 18/636,672 that was filed on 04/16/2024. Claims 1-11 are currently pending and are under examination. 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-11 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. Claim 1 recites “…a first detector that irradiates the inlet with the light having the predetermined wavelength…” in line 15-16 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130A (the first detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed first detector. It is not clear how the first detector is able to irradiates the inlet with the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 1 recites “…a second detector that irradiates the outlet with the light having the predetermined wavelength…” in line 18-19 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130B (the second detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed second detector. It is not clear how the second detector is able to irradiates the outlet with the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 4 recites “…the first detector comprises a first detection head that emits the light having the predetermined wavelength…” in line 2-3 of the claim. It is not clear how a detector head can irradiates a light. As the name of the structure 31A (the first detector head) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed first detector head. It is not clear how the first detector head that emits the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 4 recites “…the second detector comprises a second detection head that emits the light having the predetermined wavelength…” in line 4-5 of the claim. It is not clear how a detector head can irradiates a light. As the name of the structure 31B (the second detector head) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed second detector head. It is not clear how the second detector head that emits the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 5 recites “…a first detector that irradiates the inlet with the light having the first wavelength as the predetermined wavelength…” in line 6-7 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130A (the first detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed first detector. It is not clear how the first detector is able to irradiates the inlet with the light having the first wavelength as the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 6 recites “…a first detector that irradiates the inlet with the light having the predetermined wavelength…” in line 15-16 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130A (the first detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed first detector. It is not clear how the first detector is able to irradiates the inlet with the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 6 recites “…a second detector that irradiates the outlet with the light having the predetermined wavelength…” in line 18-19 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130B (the second detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed second detector. It is not clear how the second detector is able to irradiates the outlet with the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 9 recites “…a first detector that irradiates the inlet with the light having the predetermined wavelength…” in line 16-17 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130A (the first detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed first detector. It is not clear how the first detector is able to irradiates the inlet with the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. Claim 9 recites “…a second detector that irradiates the outlet with the light having the predetermined wavelength…” in line 20-21 of the claim. It is not clear how a detector can irradiates a light. As the name of the structure 130B (the second detector) in Fig. 5 indicates it is configured to detect a light reflected from the target. There is no light emitting structure indicated on structure shown in the figures or described in the specification on the claimed second detector. It is not clear how the second detector is able to irradiates the outlet with the light having the predetermined wavelength as claimed. Appropriate correction/clarification required. All the dependent claims are rejected under the same rational as the rejection of their respective parent claim to their sole dependency from the rejected claims.
