Office Action

§103
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 01/30/2026 has been entered. Response to Amendment Claims 31-33, 35-43, 45-50 are pending. Claims 42, 43, 45-50 are withdrawn. Claims 31, 42 are currently amended. Claims 1-30, 34, and 44 are canceled. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. The following claim limitations are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: Claim 31, and 39: “connection feature” reads as “a feature (generic placeholder) for connecting (function)…”. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. The connection feature is defined as an upper portion of the sidewall as per paragraph 66 or recess in view of paragraph 62, the drawings and claims. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim(s) 31, 32 35, 36, and 38-41 is/are rejected under 35 U.S.C. 103 as being unpatentable over Duvigneau (US 20070194543) in view of Hoppe (US 20160023349). Regarding claim 31, Duvigneau discloses, A rolling toolbox (Fig. 1-5) comprising: a container including a base (See annotated fig. below), a plurality of sidewalls (See annotated fig. below) at least partially defining an outer wall of an interior compartment (See annotated fig. below), a lid (180) coupled to one of the sidewalls (Fig. 4A, B), and a latch (See annotated fig. below), the lid movable between a closed portion (Fig. 4B) and an open position (Fig. 5), the interior compartment being accessible while the lid is in the open position (Fig. 5), the interior compartment being covered while the lid is in the closed position (Fig. 4B), the lid includes periphery projecting (See annotated fig. below) from a surface of the lid, and configure to engage with the plurality of sidewalls of the containers ( the periphery engages with the sidewall via the latches), wherein the latch selectively engages the periphery to secure the lid in the closed position (latch as annotated engages with periphery to lock and unlock the lid) , further wherein the periphery is dimensioned to engage a complementary feature positioned on the base of another container (the periphery is dimensioned to engage with a base 240 as shown in fig. 4a, 4b, the base 240 is shown to fit perfectly within the periphery of the lid) wherein the lid is and releasably secured to the other container in a stacked relationship, the container including at least a first connection feature (See annotated fig. below), a wheel (166) rotatably coupled to the container and supporting the container for movement on a support surface; and a handle (Fig. 5; 198) coupled to the container to guide movement of the container, the handle being movable between a retracted position and an extended position (Para 66). However, Duvigneau does not disclose, a lid coupled to one of the sidewalls by a hinge, and a latch, wherein the lid is movable about the hinge between a closed portion and an open position. Hoppe discloses, a container comprising a lid coupled to one of the sidewalls by a hinge (Fig. 2; 260), wherein the lid is movable about the hinge between a closed portion and an open position 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 Duvigneau to have a lid coupled to one of the sidewalls by a hinge, and a latch, wherein the lid is movable about the hinge between a closed portion and an open position as taught by Hoppe for the purpose of preventing loss of the lid during usage. The limitation “a first connection feature configured to engage a mating feature of a bin, divider, small parts organizer received within the interior compartment” is considered to be intended use. Examiner asserts that the recitation of intended use or purpose of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use or fulfilling said purpose, then it meets the claim. Herein a first connection feature an upper end of the sidewall is capable of being used as an area that allows for bins with hook to be attached to the container. PNG media_image1.png 500 533 media_image1.png Greyscale Regarding claim 32, Duvigneau discloses, the handle is a telescopic handle (para 17) configured to be telescoped between retracted position and the extended position (para29). Regarding claim 35, and 36 Duvigneau discloses, wherein the first connection feature is positioned on a peripheral edge of at least one of the sidewalls (See annotated fig. above for claim 31), the mating feature is a hook (174 is hook shape). The limitation “wherein the mating feature is a hook configured to selectively engage the first connection feature, and the hook can selectively engage the first connection feature in one of a first orientation and a second orientation.” is considered to be intended use. Examiner asserts that the recitation of intended use or purpose of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use or fulfilling said purpose, then it meets the claim. Herein, a bin with a hook can be attached to the perimeter of the toolbox and thereby is capable of performing the limitation as claimed. Regarding claim 38, Duvigneau discloses, the first connection feature comprises an upper portion of at least one of the plurality of sidewalls (See annotated fig. of claim 31. Regarding claim 39, and 40, Duvigneau discloses a second connection feature (See annotated fig. below). PNG media_image2.png 500 616 media_image2.png Greyscale The limitation “configured to engage a mating feature of an accessory with at least a portion of the accessory positioned outside of the interior compartment, and configured to receive a hook” is considered to be intended use. Examiner asserts that the recitation of intended use or purpose of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use or fulfilling said purpose, then it meets the claim. Herein, the upper sidewall perimeter as annotated is capable of engaging with an accessory with a hook wherein the accessory positioned outside of the interior compartment. Regarding claim 41, Duvigneau as modified discloses, the feature comprising a tab (142). Claim(s) 33 is/are rejected under 35 U.S.C. 103 as being unpatentable over Duvigneau-Hoppe as applied to claim 31 in view of Moore (US 6073944). Regarding claim 33, Duvigneau as modified does not disclose, handle is removable from the container. Moore discloses a container comprising a removable telescopic handle (claim 4). 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 Duvigneau to have the handle removable as taught by Duvigneau as it would allow for a single handle to be used with plurality of container interchangeably and thus reducing manufacturing cost. Claim(s) 37 is/are rejected under 35 U.S.C. 103 as being unpatentable over Duvigneau-Hoppe as applied to claim 31 in view Larson (US 20120318792). Regarding claim 37, Duvigneau as modified does not disclose, an interior surface of the lid includes protrusions. Larson discloses, a container (Fig. 1A, B) comprising a lid 6 wherein an interior surface of the lid includes protrusions (17; Fig. 1B; Para 26). 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 Duvigneau to incorporate an interior surface of the lid includes protrusions as taught by Larson for the purpose of providing stability to the bins/articles placed within the containers. The limitation “configured to substantially engage an upper edge of the bin, divider, or small parts organizer positioned within the interior compartment while the lid is in the closed position.” is considered to be intended use. Examiner asserts that the recitation of intended use or purpose of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use or fulfilling said purpose, then it meets the claim. Herein, the projections are capable of performing the limitation as claimed. Response to Arguments Applicants argument with regards to the limitation “connection feature” being interpreted under 112(f) is not persuasive. Claims 31 and 39 fails to disclose enough structural limitation as claimed and would not be understood by a person of ordinary skill in the art. Once 112(f) invoked, the claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. Applicants argument with regards to newly amended limitations being not disclosed by prior art of Duvigneau is considered but not persuasive since the prior art does disclose, “the lid including a periphery projecting from a surface of the lid and configured to engage with the plurality of sidewalls of the container” the lid 180 engages with the sidewalls through the latches. The latch attach the periphery of the lid to the sidewall which can be seen in fig. 4, 5. Secondly, the limitation “the periphery is dimensioned to engage a complementary feature positioned on the base of another container” is also disclosed by Duvigneau since the base of bag (230) is fitted within the perimeter and depression 240 of the base is attached via sliding latch 246 (Fig. 6). Conclusion All claims are identical to or patentably indistinct from, or have unity of invention with claims in the application prior to the entry of the submission under 37 CFR 1.114 (that is, restriction (including a lack of unity of invention) would not be proper) and all claims could have been finally rejected on the grounds and art of record in the next Office action if they had been entered in the application prior to entry under 37 CFR 1.114. Accordingly, THIS ACTION IS MADE FINAL even though it is a first action after the filing of a request for continued examination and the submission under 37 CFR 1.114. See MPEP § 706.07(b). 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 nonprovisional extension fee (37 CFR 1.17(a)) 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.
