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 .
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 1-8 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 the limitation the rotary bearing in line 7 of the claim. It is unclear if the rotary bearing of line 7 that forms the axis of ration of the bearing bore and pin are the same as or different from the rotary bearing in line 4 which defines the connection between the connection plate and the load application plates. As best understood from the specification and drawings, the “rotary bearing[s]” are different structures indicated by reference numeral 27 (bearings between the connection and load application plate, perpendicular to the travel axis) and 147/149 (bearing that is parallel to the travel axis). For purposes of examination and for consistency with the disclosure, the rotary bearings in lines 4 and line 7 are treated as two different bearings.
Claim 5 recites the limitation the first bearing plate in line 2 of the claim.  There is insufficient antecedent basis for this limitation in the claim.
The remainder of the claims are indefinite as a result of their dependency from claim 1.
Claim Rejections - 35 USC § 103
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) 1-3, 5, and 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent No. 5,896,708 to Doi et al. (“Doi”).
Regarding claim 1, Doi in Fig. 5 discloses a console for retractable roofs and facades comprising a load application plate (Ra), a connection plate (56), and a mechanical interface (52, 53, 55), wherein the connection plate (56) is connected to the load application plate (Ra) by means of a rotary bearing (57), wherein the mechanical interface comprises at least one first bearing plate (52) with a bearing bore (where 53 is inserted)) and at least one second bearing plate (55) arranged on the connection plate (56) with a bearing bore (where 53 is inserted) and a bearing pin (53), wherein an axis of rotation of the rotary bearing formed by the bearing bores and the bearing pin (53) runs parallel to a direction of travel (X-direction extending out of the page) of the console.  Doi does not disclose two load application plates (Ra). It has been held that a mere duplication of parts, such as the duplication of the load application plates, has no patentable significance unless a new and unexpected result is produced. A duplication of parts is generally recognized as being within the level of ordinary skill in the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1955). Duplicating the plates (Ra) would allow for longer spans.
Regarding claim 2, Doi discloses that the rotary bearings between the connection plate (56) and a load application plate (Ra) comprise a bearing pin (pin through 57) and a recess interacting with the bearing pin (pin through 57), and in that the axes of rotation of the rotary bearings formed thereby run orthogonally to a direction of travel (X-direction) of the console.
Regarding claim 3, Doi discloses that the connection plate (56) has a reinforcement (upstanding central flange of 56 through which pin 54 is inserted) on its upper side, and in that the at least one second bearing plate (139) is connected to the reinforcement (135).
Regarding claim 5, Doi discloses that a first bearing plate (52) at its end opposite the bearing bore (through which 53 is inserted) is connected to a support (1a) or a flange plate.
Regarding claim 7, Doi discloses that the load application plate (Ra) is part of a linear guide, and in that the linear guide comprises one or more carriages (58) and a guide rail (Rg).
Allowable Subject Matter
Claims 3, 6, and 8 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
None of the prior art alone or in obvious combination discloses applicant’s invention as recited in claims 3, 6, and 8. The closest prior art to Doi discloses the bearing bore above, not beneath the connection plate, the connection plate does not surround the load application plate which is spaced from the connection plate, and does not disclose the load application plate connected to carriage of a guide. Moreover cited art DE102020122733.7 is commonly owned and published after the effective filing date of the instant application and therefore does not constitute as prior art.
Conclusion


NEXT OFFICE ACTION: 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 .
Claim Rejections - 35 USC § 103
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) 1-3, 5, and 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent No. 5,896,708 to Doi et al. (“Doi”).
Regarding claim 1, Doi in Fig. 5 discloses a support for movable roofs and facades comprising a load introduction plate (Ra), a connection plate (56), and a mechanical interface (52, 53, 55), wherein the connection plate (56) is rotatably connected to the load-introduction plate (Ra) by means of a respective first rotary bearing (57), wherein the mechanical interface comprises at least one first bearing plate (52) with a bearing bore (where 53 is inserted), at least one second bearing plate (55) having a bearing bore (where 53 is inserted), the second bearing plate (55) being disposed on the connection plate (56), and a bearing pin (53), wherein an axis of rotation of the second rotary bearing formed by the bearing bores and the bearing pin (53) runs parallel to a direction of travel (X-direction extending out of the page) of the support.
Doi does not disclose two load-introduction plates (Ra). It has been held that a mere duplication of parts, such as the duplication of the load-introduction plates, has no patentable significance unless a new and unexpected result is produced. A duplication of parts is generally recognized as being within the level of ordinary skill in the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1955). Duplicating the plates (Ra) would allow for longer spans.
Regarding claim 2, Doi discloses that the rotary bearings between the connection plate (56) and a load -introduction plate (Ra) comprise a bearing pin (pin through 57) and a recess interacting with the bearing pin (pin through 57), and in that the axes of rotation of the rotary bearings formed thereby run orthogonally to a direction of travel (X-direction) of the support.
Regarding claim 3, Doi discloses that the connection plate (56) has a reinforcement (upstanding central flange of 56 through which pin 54 is inserted) on its upper side, and in that the at least one second bearing plate (139) is connected to the reinforcement (135).
Regarding claim 5, Doi discloses that a first bearing plate (52) at its end opposite the bearing bore (through which 53 is inserted) is connected to a support (1a) or a flange plate.
Regarding claim 7, Doi discloses that the load -introduction plate (Ra) is part of a linear guide, and in that the linear guide comprises one or more carriages (58) and a guide rail (Rg).
Allowable Subject Matter
Claims 3, 6, and 8 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
None of the prior art alone or in obvious combination discloses applicant’s invention as recited in claims 3, 6, and 8. The closest prior art to Doi discloses the bearing bore above, not beneath the connection plate, the connection plate does not surround the load -introduction plate which is spaced from the connection plate, and does not disclose the load -introduction plate connected to carriage of a guide. Moreover cited art DE102020122733.7 is commonly owned and published after the effective filing date of the instant application and therefore does not constitute as prior art.
Response to Arguments
Applicant's arguments filed 6/21/2024 have been fully considered but they are not persuasive.
Applicant's arguments fail to comply with 37 CFR 1.111(b) because they amount to a general allegation that the claims define a patentable invention without specifically pointing out how the language of the claims patentably distinguishes them from the references.
Applicant's arguments do not comply with 37 CFR 1.111(c) because they do not clearly point out the patentable novelty which he or she thinks the claims present in view of the state of the art disclosed by the references cited or the objections made. Further, they do not show how the amendments avoid such references or objections.
Mere finding of novelty or inventive step by the International searching authority is not necessarily determinative in applications coming before the Office. The examiner continues to assert that the claims are not allowable over the cited references, as explained in detailed in the 35 U.S.C. 103 rejection above. One reason being is that the examiner interpreted Doi differently with other structures of Doi anticipating or rendering obvious the claimed structure. Moreover, the language of the claims as currently written do not require three rotary bearings with each of the two load-introduction plates requiring a bearing as cited by the International Search Authority as the reason for the finding of inventive step. While the claim requires two load-introduction plates, the claim does not appear to require for each of the two load-introduction plates to have a first rotary bearing.
Conclusion
THIS ACTION IS MADE FINAL.  Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.  In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action.  In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
