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. Claims 6 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Ungurean (US 2006/0165486) in view of Hilton (US 3377931). Regarding claims 6 and 14, Ungurean fails to discloses or fairly the bottom slot portion is disposed in the bottom hook proximal portion; and wherein the locking bar is a rectangular locking bar disposed above the top hook distal portion and the bottom hook distal portion. However, Hilton discloses fairly the airfield matting system having an end to end connection comprising the bottom slot portion is disposed in the bottom hook proximal portion; and wherein the locking bar is a rectangular locking bar disposed above the top hook distal portion and the bottom hook distal portion (the lower connecting means 44b, 44c, 44d and the locking bar 46 disposed above lower connecting means, see Fig.3, col.3, line 38 - col.4, line 24 ) . Therefore, it would have been obvious to one of ordinary skill in the art before effective filing date to modify Ungurean’s connecting system as taught by Hilton in order to improve the interlocking function for stronger connection between the panels. Claims 8, 16 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Ungurean (US 2006/0165486) Regarding claims 8 and 16, Although Ungurean fails to specifically disclose the locking bar slot is an inclined slot which is inclined at an angle of about 10°- 30° relative to horizontal, downward on a side of the top hook distal portion and upward on a side of the bottom hook distal portion, it would have been obvious to one of ordinary skill in the art before effective filing date to modify Ungurean’s connecting system with providing the locking slot with 10-30 degree angle relative to horizontal in order to improve the interlocking function for stronger connection between the panels. Regarding claim 20, Ungurean discloses the top hook comprises a J-shaped top hook having a generally vertical orientation as a generally upright top hook having a top hook distal portion oriented generally vertically upward; wherein the bottom hook comprises a J-shaped bottom hook having a generally vertical orientation as a generally inverted vertical bottom hook having a bottom hook distal portion oriented generally vertically downward; and wherein the top hook distal portion and the bottom hook distal portion are disposed adjacent to one another (see Fig. 7, Para [0041] & [0054]). Although Ungurean fails to specifically disclose the locking bar slot is an inclined slot which is inclined at an angle of about 10°- 30° relative to horizontal, downward on a side of the top hook distal portion and upward on a side of the bottom hook distal portion, it would have been obvious to one of ordinary skill in the art before effective filing date to modify Ungurean’s connecting system with providing the locking slot with 10-30 degree angle relative to horizontal in order to improve the interlocking function for stronger connection between the panels. Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Ungurean (US 2006/0165486) in view of Perry (US 3572224). Regarding claim 17, Ungurean fails to disclose or fairly suggest the first end connector includes a first end connector insert configured to slide in between ribs of the first end of the rectangular mat core; wherein the second end connector includes a second end connector insert configured to slide in between ribs of the second end of the rectangular mat core. However, Perry discloses a load supporting plank system having a connecting system comprising a first end connector insert/side element 12/right side, 16 configured to slide in between ribs of the first end of the rectangular mat core; wherein a second end connector/side element 12/left side, 17 includes a second end connector insert configured to slide in between ribs of the second end of the rectangular mat core (adjoining these side elements into the panel/ honeycomb structure 40 as inserts with using epoxy material 41, see Figs 1-2, col.4, lines 25-47). Therefore, it would have been obvious to one of ordinary skill in the art before effective filing date to modify Ungurean’s end connecting system as taught by Perry in order to easily change the end connector parts with various interlocking features as to the design. Relevant Prior art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
