Allowable Subject Matter
Claim 21 is 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.
Response to Arguments
Applicant's arguments filed 16th May 2024 have been fully considered but they are not persuasive.
In response to applicant's argument regarding combination of Stanley ‘832 and Behzadpour ‘060 in claims 1, 6, 13, 16 and 18-19, the test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references.  Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.  See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981). Stanley ‘832 teaches coupling strut to a rib of a wing of an aircraft and Behzadpour ‘060 teaches coupling the outer wing front spar and the outer wing rear spar (214) via splice plates. Since coupling is being done on a wing portion of an aircraft in both Stanley ‘832 and Behzadpour ‘060 it would have been obvious to use splice plates of Behzadpour ‘060 to couple strut to a rib of a wing in Stanley ‘832. Also the coupling system couples on top and bottom portion of the wing and couples rear portions of the strut to front portions of the rib.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action.  Accordingly, THIS ACTION IS MADE FINAL.  See MPEP § 706.07(a).  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 date of this final action.
