OFFICE ACTION:
Notice of Pre-AIA  or AIA  Status
This is a first office action on the merits for application serail number 18/220,251 filed 7/10/23.  This action is in response to the preliminary amendment filed 7/24/23.  Claims 9-17 are pending.  Claims 1-8 have been canceled. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on 2/08/23. It is noted, however, that applicant has not filed a certified copy of the Chinese application as required by 37 CFR 1.55.
The replacement drawing sheets filed 7/24/23 have been approved for entry but are objected to for the reasons below.
The drawings are objected to because:
the view numbers must be larger than all of the reference numbers (#& CFR 1.84(u)(2)); and
As the substitute specification filed 7/24/23 has not yet been entered (See below) the drawings are replete with reference numbers not found in the specification (receipt of a no new matter statement will allow entry of the substitute specification).
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.
The drawings are objected to under 37 CFR 1.83(a).  The drawings must show every feature of the invention specified in the claims.  Therefore, the connection between the second ends of the elastic rod mechanisms and the tarpaulin [cl. 1] must be shown or the feature(s) canceled from the claim(s).  No new matter should be entered.
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.
The substitute specification filed 7/24/23 has NOT been entered because it does not conform to 37 CFR 1.125(b) and (c) because: it was not accompanied by a no new matter statement as required by 37 CFR 1.125(b).  The no new matter statement in the remarks filed 7/24/23 fails to address the substitute specification.
The disclosure is objected to because of the following informalities: the specification filed 7/10/23:
uses refence number 3 for both the tarpaulin and elastic rod mechanism;
Uses reference number 1 and 2 for the tent frame assembly;
Uses refence number 2 for both the tent frame assembly and the ceiling assembly; and
Fails to clearly distinguish between the lateral folding arm mechanism and the fold arm mechanisms annularly distributed about a periphery of the central lock mechanism.
Appropriate correction is required.  Each of the above objections appear to be overcome by the substitute specification filed 7/24/23 which will be entered upon receipt of the required no new matter statement (“The substitution specification filed 7/24/23 contains no new matter”).
Claim 10 is objected to because of the following informalities: line 1 ends with an erroneous “the” (“the each” should just read as “each”).  Appropriate correction is required.
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 9 and 14-17 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. 2003/0183266 to Suh in view of U.S. Patent 2,518,167 to Mintz.
Suh provides a foldable canopy tent comprising a rectangular tent frame  assembly 1, legs 10 connected by lateral “arm assemblies” 20 and a roof or “ceiling” assembly mounted on the tent frame assembly comprised of  plurality (four) of  pole members 46 considered to meet the limitation of “foldable arm mechanisms” distributed around a central joint assembly 8 or “lock mechanism” and a plurality (four) of supplement poles 56 or “elastic rod mechanisms” annularly distributed about assembly 8.  The poles 56 are pivotally or “rotatably connected at their first ends to assembly 8 and their second or free ends hold the tent cloth/canopy (not shown) considered to meet the limitation of a “tarpaulin” in tension [0057].
Suh fails to provide that the second ends of the poles 56 are connected to the tarpaulin.
Mintz teaches that at the time of the effective filing date of the invention it was know that a canopy 11 of foldable tent may be connected to the ceiling frame members with loops 40.
It would have been obvious at the time of the effective filing date of the invention to one having ordinary skill in the art that the cover of Suh could have been connected to the pole members 46 and 56 with loops as taught by Mintz to provide known a means of securing the covering thereto.
Moreover, all the claimed elements are known in the prior art and one skilled in the art would have combined the elements at the time of the effective filing date of the invention as claimed by known methods with a reasonable expectation of success with no change to their respective functions, and the combination would have yielded predictable results to one having ordinary skill in the art of connecting a cover or ”tarpaulin” to the underlying support frame.
Claims 10-13 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.
The following is a statement of reasons for the indication of allowable subject matter: a vertex elastic rod and supporting elastic rod fixed to upper and lower discs respectively is not taught or adequately suggested in the prior art of record.
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.  Note in particular:
Poles 25 of US 2020/0157838 to Yuan et al.
Link units 121 of U.S. 2015/0308147 to Lee which extend between arm assemblies 109 from a central lock to lateral arms.
US 2015/0247339 to Lee.
U.S. Patent 8,590,553 to Lovely, U.S. Patent 4,558,713 to Hagler et al. and US 2008/0066795 to Sy-Facunda each provide intermediate rod assemblies extending from a central hub to lateral arms.
Straps 46 of US 2010/0275959 to Lane et al.
Canopy attachment means in Fig. 5 of U.S. Patent 4,941,500 to Emard.

APPLICANT REBUTTAL: Remarks
The Present Invention and the Pending Claims
Claims 10-17 are currently pending. Reconsideration and allowance of the pending claims is respectfully requested.
Summary of the Office Action
Allowable Subject Matter
Claims 10-13 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.
Priority
Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on 2/08/23. It is noted, however, that applicant has not filed a certified copy of the Chinese application as required by 37 CFR 1.55.
Objection to the drawings
The drawings are objected to because: a. the view numbers must be larger than all of the reference numbers (#& CFR
(u)({2)); and
b. As the substitute specification filed 7/24/23 has not yet been entered (See below) the drawings are replete with reference numbers not found in the specification (receipt of a no new matter statement will allow entry of the substitute specification). 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.
The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the connection between the second ends of the elastic rod mechanisms and the tarpaulin (cl. 1] must be shown or the feature(s) canceled from the claim(s). No new matter should be entered.
Objection to the specification
The substitute specification filed 7/24/23 has NOT been entered because it does not conform to 37 CFR 1.125(b) and (c) because: it was not accompanied by a no new matter statement as required by 37 CFR 1.125(b}. The no new matter statement in the remarks filed 7/24/23 fails to address the substitute specification.
The disclosure is objected to because of the following informalities: the specification filed 7/10/23:
c. uses refence number 3 for both the tarpaulin and elastic rod mechanism; d. Uses reference number 1 and 2 for the tent frame assembly; e. Uses refence number 2 for both the tent frame assembly and the ceiling assembly; and f. Fails to clearly distinguish between the lateral folding arm mechanism and the fold arm mechanisms annularly distributed about a periphery of the central lock mechanism. Appropriate correction is required. Each of the above objections appear to be overcome by the substitute specification filed 7/24/23 which will be entered upon receipt of the required no new matter statement ("The substitution specification filed 7/24/23 contains no new matter').
Claim Objections
Claim 10 is objected to because of the following informalities: line 1 ends with an erroneous "the" ("the each" should just read as "each"). Appropriate correction is required.
Claim Rejections - 35 USC Q 103
Claims 9 and 14-17 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. 2003/0183266 to Suh in view of U.S. Patent 2,518,167 to Mintz.
Amendments to the claims
Claims 10, 14, 15, and 17 are currently amended; claims 11-13, and 16 remain as previously presented; claims 1-8 were previously canceled; claim 9 is now canceled. Applicant respectfully submits that the claim amendments do not add new subject matter.
The office action states: "Claims 10-13 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."
Applicant appreciates identification of claims 10-13 as allowable by the examiner, subject to rewriting the claims in independent form including all of the limitations of the base claim and any intervening claims. As suggested in the office action, applicant has amended the claim 10 by including all the limitations of its base claim 9 in claim 10. Therefore, applicant respectfully requests allowance of amended claim 10.
Amended claims 11-17 are dependent on allowable amended claim 10. Therefore, applicant respectfully requests allowance of amended claims 11-17.
The office action further states: "Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on 6/24/2022. It is noted, however, that applicant has not filed a certified copy of the Chinese application as required by 37 CFR 1.55."
In response to the above objection, applicant has filed a certified copy of the Chinese application as required by 37 CFR 1.55. Therefore, applicant respectfully requests that the above objection be reconsidered and withdrawn.
The office action further states: "The drawings are objected to because: a. the view numbers must be larger than all of the reference numbers (#& CFR
(u)({2)); and
b. As the substitute specification filed 7/24/23 has not yet been entered (See below) the drawings are replete with reference numbers not found in the specification (receipt of a no new matter statement will allow entry of the substitute specification).
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. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the connection between the second ends of the elastic rod mechanisms and the tarpaulin (cl. 1] must be shown or the feature(s) canceled from the claim(s). No new matter should be entered."
In response to the above objection, applicant is herewith submitting replacement drawings as specified in the office action. Therefore, applicant respectfully requests that the above objection to the drawings be reconsidered and withdrawn.
The office action further states: "The substitute specification filed 7/24/23 has NOT been entered because it does not conform to 37 CFR 1.125(b) and (c) because: it was not accompanied by a no new matter statement as required by 37 CFR 1.125(b}. The no new matter statement in the remarks filed 7/24/23 fails to address the substitute specification.
The disclosure is objected to because of the following informalities: the specification
filed 7/10/23:
c. uses refence number 3 for both the tarpaulin and elastic rod mechanism; d. Uses reference number 1 and 2 for the tent frame assembly;
e. Uses refence number 2 for both the tent frame assembly and the ceiling assembly; and
f. Fails to clearly distinguish between the lateral folding arm mechanism and the fold arm mechanisms annularly distributed about a periphery of the central lock mechanism.
Appropriate correction is required. Each of the above objections appear to be overcome by the substitute specification filed 7/24/23 which will be entered upon receipt of the required no new matter statement ("The substitution specification filed 7/24/23 contains no new matter')."
In response to the above objection, applicant has submitted a proper statement of no new subject matter as specified in the office action. Furthermore, applicant has re- submitted the substitute specification that overcomes the part number duplication referenced above. Therefore, applicant respectfully requests that the above objection to the disclosure be reconsidered and withdrawn. Furthermore, applicant respectfully requests that the substitute specification and replacement drawings be reconsidered and entered into the records.
The office action further states: "Claim 10 is objected to because of the following informalities: line 1 ends with an erroneous "the" ("the each" should just read as "each"). Appropriate correction is required."
In response to the above objection, applicant has amended the claims as suggested in the office action. Therefore, applicant respectfully requests that the above objection to the claims be reconsidered and withdrawn.
The office action further states: "Claims 9 and 14-17 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. 2003/0183266 to Suh in view of U.S. Patent 2,518,167 to Mintz."
In response to the above rejection, applicant has canceled claim 9. Therefore, the rejection of claim 9 is moot. Furthermore, applicant has amended claims 14-17, and made claims 14-17 dependent on allowable amended claim 10. Therefore, applicant respectfully requests that the rejection of claims 14-17 under 35 U.S. C. 103 be reconsidered and withdrawn.
Conclusion

NEXT OFFICE ACTION: Notice of Pre-AIA  or AIA  Status
This office action is in response to the amendment filed 5/06/25.  Claims 10-17 are pending. Claims 1-9 have been canceled. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
The substitute specification filed 5/06/25 has been entered.
The replacement drawing sheets are approved.
Claims 10-17 are allowed.
The arguments filed 5/06/25 never specifically address where the connection between the second ends of the elastic rod mechanisms and the tarpaulin are show. However, the objection is section 5 of the office action mailed 4/14/25 is withdrawn as one skilled in the art would recognize a connection to the tarp at the second ends from Fig. 1.
Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on 2/08/23. It is noted, however, that applicant has not filed a certified copy of the Chinese application as required by 37 CFR 1.55.  The arguments filed 5/06/25 indicate that the copy has been filed but it still has not been received.
