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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection.  Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.  Applicant's submission filed on 09/11/2024 has been entered.
Response to Arguments
Applicant’s arguments, see pages 1-3, filed 09/11/2024, with respect to Claims 1 and 8 have been fully considered and are persuasive.  The rejection of Claims 1-10 and 14 has been withdrawn.
Applicant's arguments filed 09/11/2024 with respect to Claim 15 have been fully considered but they are not persuasive. Regarding independent Claims 1 and 8, Examiner agrees that the amended limitations in view of the claim limitations relating to the relationship between the first and second tray, the mating surfaces and top skin (Claim 1), and relating to the relationship between the flanges, mating surfaces and top skin (Claim 8) are not disclosed by Huber (‘462) in view of Huber (‘984). However, regarding Claim 15, Examiner would like to make reference to Columns 2-3, lines 64-7 of Huber (984) wherein it is disclosed that there can be an almost infinite number of configurations of the ball-mat contours and openings due to the building-block system by connecting the side profiles with corner pieces, which could easily be formed to extend throughout four sides of a cargo compartment. Further, it would have been an obvious matter of design choice to make the different portions of the ball mat of whatever form or shape was desired or expedient. A change in form or shape is generally recognized as being within the level of ordinary skill in the art, absent any showing of unexpected results. In re Dailey et al., 149 USPQ 47. Therefore, it would have been a mere matter of design choice to make the ball mat the size and shape as claimed, which would inherently teach the feature of the plurality of trays covered from the first longitudinal end to the fourth longitudinal end, as Figure 7 of Huber (‘984) shows that the cover plate (11) covers all elements of the ball mat besides the rotatable balls that will sit in the holders (13).
Regarding Claims 16 and 18-24, Applicant does not provide any arguments based upon the claims respective rejections other than to state these claims are believed to be allowable due to Amended Claims 1, 8 and 15.
For the foregoing reasons, the claims stand rejected.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 15, 16, 18 and 21-24 are rejected under 35 U.S.C. 103 as being unpatentable over Huber (United States Patent US 7,556,462 B2) in view of Huber (United States Patent 6,125,984 A) .
Claims 19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Huber (United States Patent US 7,556,462 B2) in view of Huber (United States Patent 6,125,984 A) in further view of Schoen (United States Patent Application US 2017/0313423 A1).

Marked up Figure 2: Huber ‘462
Regarding Claim 15, Huber (US 7,556,462) discloses a cargo handling system (Column 1, lines 17-18: “cargo deck for a cargo hold”), comprising: a plurality of trays (Figure 1: Profiles 10, 10-1, 10-2, 10-3); a top skin (Figure 1: Ball Mats 21 and Ball elements 53) disposed on and mated to a top surface of each of the plurality of trays (Figure 1: Trays are covered by Ball Mats 21 and Ball elements 53); a ball transfer unit (BTU) coupled, and disposed partially within, the top skin (Figure 3: Ball transfers composed within Ball Elements 53), the BTU comprising: a retaining fixture including a flange and a housing (Figure 3: Flange (Shown by circle surrounding ball rollers) and housing of Ball rollers composed within Ball Elements 53 and Ball Mats 21), the flange mated to the top skin (Figure 3: Flange (Circle surrounding Ball rollers on Ball elements 53) has its bottom surface mated to the top surface of Ball elements 53); and a spherical ball disposed partially within the housing (Figure 3: Ball rollers of Ball elements 53 disposed partially within housing), wherein: the plurality of trays are contiguously covered over an entirety of the plurality of trays, and each of the plurality of trays is disposed entirely below the top skin (Figure 1: Shows the top skin composed over a plurality of trays (10, 10-1, 10-2, 10-3) to create the conveying area of the workpieces (area by door region 55), and is covered over the entirety of the trays in the conveying section).
However, Huber (‘462) does not disclose a cargo compartment extending from a first longitudinal end at an aft end of a cargo deck of the cargo compartment through an aft section to a second longitudinal end proximate an aft end of a cargo door, longitudinally from the second longitudinal end proximate the aft end of the cargo door to a third longitudinal end proximate a forward end of the cargo door, and longitudinally from the third longitudinal end through a forward section forward to a fourth longitudinal end proximate a forward end of the cargo deck; and wherein the plurality of trays are continuously covered from the first longitudinal end to the fourth longitudinal end.
Huber (US 6,125,984) teaches a similar cargo handling system (Column 1, lines 4-6: “a ball mat for the loading deck of an aircraft, to support cargo and assist the movement thereof.”) comprising a cargo compartment extending from a first longitudinal end at an aft end of a cargo deck of the cargo compartment through an aft section to a second longitudinal end proximate an aft end of a cargo door, longitudinally from the second longitudinal end proximate the aft end of the cargo door to a third longitudinal end proximate a forward end of the cargo door, and longitudinally from the third longitudinal end through a forward section forward to a fourth longitudinal end proximate a forward end of the cargo deck(Column 1, lines 4-6: “The invention relates to a ball mat for the loading deck of an aircraft, to support cargo and assist the movement thereof.”, wherein the loading deck comprises four longitudinal sides inherently and further wherein Columns 2-3, lines 64-7: “In FIG. 1 an embodiment of a ball mat is viewed in perspective diagonally from above. The ball mat comprises a cover plate 11 and, parallel thereto, a floor plate 12 (cf. FIG. 2). At its sides the ball mat is bounded by side profiles 19, 20, 21, 22. The side profiles 19, 20, 21, 22 are joined to one another by corresponding outer corner pieces 53, 54, 55 and 56, which can be inserted into the side profiles. By the use of this technique, with appropriate modification of cover plate 11 and floor plate 12 there are almost infinitely many possible configurations of the ball-mat contours and openings (building-block system).”); and wherein the plurality of trays are continuously covered from the first longitudinal end to the fourth longitudinal end (Figure 1: Shows the cover 11 covering the entirely of the ball mat).
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 Huber (US 7,556,462 B2) to incorporate the cargo compartment as taught by Huber (US 6,125,984 A). The motivation for the modification would have been to make the ball mat more resistant, stiffer without adding weight, splash proof/ water-repellent and to overall allow loads on the mat to be more uniformly distributed by allowing the loads imposed on the ball elements to be borne simultaneously by the cover plate (Column 1, lines 18-27 and lines 44-47).
Regarding Claim 16, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 15, as seen above. Huber (‘462) further discloses wherein the housing of the retaining fixture is disposed at least partially within a first tray in the plurality of trays (Figure 3: Shows housing of Ball rollers of Ball Elements 53 partially disposed in profile 10).
Regarding Claim 18, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 15, as seen above. Huber (‘462) further discloses the retaining fixture (Figure 3: Shows housing of Ball rollers of Ball Elements 53 disposed in Profile 10). Huber (‘984) further discloses wherein the retaining fixture is configured to be press fit into the top skin (Figure 7: Shows the fitting configured to press fit into cover 11, wherein Column 3, lines 43-47: “The holder 13 for the ball element 15, which is indicated only schematically in FIG. 2, stands on the floor plate 12 by way of devices including an annular projection 29 or a circumferential collar.”).
Regarding Claim 19, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 15, as seen above.
However, Huber (‘462) in view of Huber (‘984) does not disclose wherein the plurality of trays are made of a composite material.
Schoen teaches a similar cargo handling system (Figure 1: System 10) wherein the plurality of trays are made of a composite material (¶0008, lines 2-4: “This floor may comprise all suitable materials that withstand the gravitational forces of the loads, such as metal, plastic or composite materials”).
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 Huber (‘462) in view of Huber (‘984) to incorporate the composite material as taught by Schoen. The motivation for the modification would have been to allow the system to withstand the gravitational forces of the loads (¶0008, lines 2-4), which can allow for economical operation and as efficient loading and unloading of loads as possible (¶0006, lines 1-3).
Regarding Claim 20, Huber (‘462) in view of Huber (‘984) in further view of Schoen discloses the cargo handling system of Claim 19, as seen above. Schoen further discloses wherein the top skin comprises a metal top surface (¶0013, lines 1-5: “The guideway may, in general, comprise the same materials as the cargo compartment floor, and, in particular, materials that allow a, preferably, low-loss movement of the transport vehicle along the guideway, such as metal, plastic or composite materials.”) and a composite structure disposed below the metal top surface (¶0008, lines 2-4: “This floor may comprise all suitable materials that withstand the gravitational forces of the loads, such as metal, plastic or composite materials”, wherein the top and bottom structures can be comprised of any of these items).
Regarding Claim 21, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 15, as seen above. Huber (‘462) further discloses wherein the top skin is configured to form a contiguous flat floor (Figure 1: Shows ball elements 53 and ball mats 21 coupled to the first and second top mating surfaces of each tray (10, 10-1, 10-2, 10-3) to create a contiguous sheet of top skin) through a cargo compartment (Figure 1: Cargo deck 50).
Regarding Claim 22, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 15, as seen above. Huber (‘462) further discloses wherein flange is disposed entirely above the top skin (Figure 3: Flange (Shown by circle surrounding ball rollers), wherein the circle surrounding the ball rollers is above the top skin).
Regarding Claim 23, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 15, as seen above. Huber (‘462) further discloses further comprising a plurality of the BTU, wherein each of the plurality of the BTU are disposed throughout the entranceway section (Figure 3: Ball transfers composed within Ball Elements 53, wherein Figure 1 shows the Bal transfers disposed over door region 55 which is the entrance to the cargo deck).
Regarding Claim 24, Huber (‘462) in view of Huber (‘984) discloses the cargo handling system of Claim 23, as seen above. Huber (‘984) further discloses further comprising a plurality of roller assemblies disposed throughout the forward section and the aft section of the cargo compartment (Figure 7: Shows the ball elements 15 disposed in holders 13, which are disposed throughout entire cargo floor).
Allowable Subject Matter
Claims 1-10 and 14 are allowed.
The following is an examiner’s statement of reasons for allowance: Regarding Claims 1-10 and 14, there is no prior art alone or in combination that teaches a cargo handling system that included the combination of recited imitations in Claims 1 and 8. The art alone or in combination did not teach wherein a cargo handling system comprised a cargo compartment, extending from four longitudinal ends; wherein a first tray extends longitudinally from a first to fourth longitudinal end, and a second tray extending longitudinally from a first to fourth longitudinal end, and wherein a top skin is disposed on and mated to the first and second top mating surface of the first and second tray (Claim 1), and wherein the trays are continuously covered from the first to the fourth longitudinal end, a top skin is disposed on and mated to a first and second top mating surfaces created from a base, sidewalls and flanges of each of the plurality of trays, wherein the flange includes a bottom surface mated to a top surface of the top skin and press fit into the top skin (Claim 8). The closest prior arts of record Huber (United States Patent US 7,556,462 B2) and Huber (United States Patent 6,125,984 A) teach a similar cargo handling system comprising a plurality of trays, a top skin disposed on the trays, and a roller assembly, but fails to teach the relationship between the structure of the cargo compartment and the first and second tray, the mating surfaces and top skin (Claim 1), and the relationship between the structure of the cargo compartment and the flanges, mating surfaces and top skin (Claim 8). Additionally, no other references, or reasonable combination thereof, could be found which disclose or suggest these features in combination with other limitations in the claims.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
United States Patent US 7,472,867 B2 (Huber, Thomas): This patent has been deemed
pertinent due to its similarities between Claims 1-20. Huber teaches a similar cargo handling
system comprising a plurality of trays, a top surface, mounting points and a roller assembly,
as seen in Figure 5.
Unites States Patent Application US 2015/0367941 A1 (Harden, Felix): This patent application has been deemed pertinent due to its similarities between Claims 1-20. Harden teaches a similar system for moving loads comprising a cargo hold floor, guide rails, roller assemblies, and a top surface as seen in Figures 1 and 4.

APPLICANT REBUTTAL: REMARKS

Claim 15 and 23 are amended and no new claims are added. Applicant requests reconsideration of the present application in light of the foregoing amendments and following remarks.
Allowed Claims
Applicant thanks the Examiner for her indication that claims 1-10 and 14 are allowed.
Re
jection under 35 U.S.C. 103
The Examiner rejects claims 15, 16, 18, and 21-24 under 35 U.S.C. 103 as being
unpatentable over U.S. Patent No. 7,556,462 (Huberl) in view of U.S. Patent No. 6,125,984 (Huber2). Applicant respectfully disagrees; however, Applicant amends claim 15 solely to expedite prosecution. Applicant amends independent claim 15 to recite "a plurality of trays eac
of
the plurality of
trays extending longitudinally from the first longitudinal end to the fourth longitudinal end, each of
the plurality of
trays including a first flange defining a first top mating surface and a second flange defining a second top mating surface"
and "a topskin disposed on and mated to [[a]]
the first
top
mating
surface
and the second top mating surface
of each of the plurality of trays." Applicant asserts that Huber1 and Huber2 fail to disclose, contemplate, or render obvious at least these limitations in addition to the other elements of claim 15. Accordingly, Applicant asserts that the rejection should be withdrawn and all pending claims are in condition for allowance.
