Office Action

§102 §103 §112
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. Drawings The drawings are objected to because the lead lines from the labels to the components are thin and difficult to read and the pins for 71 and 81 are difficult to see since it is mostly obstructed by the other components around it . Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. In addition to Replacement Sheets containing the corrected drawing figure(s), applicant is required to submit a marked-up copy of each Replacement Sheet including annotations indicating the changes made to the previous version. The marked-up copy must be clearly labeled as “Annotated Sheets” and must be presented in the amendment or remarks section that explains the change(s) to the drawings. See 37 CFR 1.121(d)(1). Failure to timely submit the proposed drawing and marked-up copy will result in the abandonment of the application. 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 appl icant regards as his invention. Claims 1-12 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 1 and 3 recites “penetratingly provided.” The limitation is indefinite because it is unclear how an object is penetrat ingly provided. Is it provided with an absence of material, i.e. a hole or through hole? This form of language is confusing and non-standard. The examiner suggests applicants strike out the term “penetratingly provided.” Claim 3 recites “jointed and communicates.” It is unclear what jointed means in this context. Does it mean that the pipes have joints that connect two different pipe sections, the pipe extends into a different angled direction resulting in a joint, or some other structure? The examiner suggests applicants strike out the term “ jointed .” Claim 7 recites “preset direction.” What constitutes a “preset” direction and if two objects are aligned in a direction does it inherently have a preset direction? The examiner suggests applicants strike out the term “preset.” Claims 2, 4-6, and 8-12 are rejected due to dependency. Claim Rejections - 35 USC § 102 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 ( i.e., changing from AIA to pre-AIA ) 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale , or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

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 ( i.e., changing from AIA to pre-AIA ) 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. Claim(s) 5-6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wuxi as applied to claim 3 above, and further in view of Liu (CN 112975176 A) Claim 5. Wuxi does not disclose t he welding positioning apparatus according to claim 3, wherein the welding positioning apparatus further comprises a position-limit structure disposed on the bottom plate, the position-limit structure being connected between the bottom plate and the main body to restrict the main body to the bottom plate. Liu discloses a laser welding apparatus wherein the head main body and the guide main body (Fig. 1) has a guide bolt fixes the head with the main body (par. 34) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Wuxi to incorporate the teachings of Liu and have the guide bolt. Doing so would have the benefit of fixing the pressing assembly with the mounting plate. Claim 6. Wuxi in view of Liu discloses t he welding positioning apparatus according to claim 5, wherein the position-limit structure is constructed as a first positioning pin protruding from the bottom plate (guiding bolt protrudes from the pressure head body) , and a first groove matching the first positioning pin is disposed on a surface (guide bolt passes through a groove in the guide body, par. 34, Fig. 3) of the main body facing toward the bottom plate . Wuxi in view of Liu does not disclose the bolt passing through the bottom plate into a groove in the pressing head. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Wuxi in view of Liu to have swapped the positions of the guide bolt such that it passes through a groove in the pressing head since it has been held that the mere reversal of parts has no patentably significance unless a new and unexpected result is produced.
