Office Action

§102 §103
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 . Election/Restrictions Applicant’s election without traverse of Species III (claims 1-4, 6-7, 10-11, 13-18, 20) in the reply filed on 3/9/2026 is acknowledged. However, upon further review, claim 4, 20 is directed to non-elected embodiment and is thus hereby WITHDRAWN. Claims 1-3, 6-7, 10-11, 13-18 are examined accordingly. Specification The disclosure is objected to because of the following informalities: No description of only one perforation tab arranged at each of the crests or troughs. Appropriate correction is required. Priority Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) is acknowledged. Applicant has not complied with one or more conditions for receiving the benefit of an earlier filing date under 35 U.S.C. 119(e) as follows: The later-filed application must be an application for a patent for an invention which is also disclosed in the prior application (the parent or original nonprovisional application or provisional application). The disclosure of the invention in the parent application and in the later-filed application must be sufficient to comply with the requirements of 35 U.S.C. 112(a) or the first paragraph of pre-AIA 35 U.S.C. 112, except for the best mode requirement. See Transco Products, Inc. v. Performance Contracting, Inc., 38 F.3d 551, 32 USPQ2d 1077 (Fed. Cir. 1994). The disclosure of the prior-filed application, Application No. 17/116,256, fails to provide adequate support or enablement in the manner provided by 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph for one or more claims of this application. No support in the prior-filed application for only one perforation tab arranged at each of the crests or troughs. It is noted that the original disclosure describes a perforation tab arranged at each of the crests or troughs but does not limit there to be only one perforation tab. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-3, 6-7, 10, 13-16 is/are rejected under 35 U.S.C. 102a1 as being anticipated by US 2018/0072459 to Davey et al. (Davey). Regarding claim 1, Davey discloses a multi-compartment tray (1) comprising first and second compartments (2a, 2b) having first and second terminal edges (8 attached to 7a, 8 attached to 7b), respectively, that extend towards one another in a first plane (A, Fig 21 below), a wave-shaped perforation region (8) having a series of undulating crests (D, Fig 21 below) and troughs (E, Fig 21 below) that extend in series with respective tangents that extend in second (B, Fig 21 below) and third planes (C, Fig 21 below) respectively, and are parallel to and laterally offset from the first plane and from each other, wherein at least some of the undulating crests and troughs comprise a perforation tab (11) formed thereon that connect the first and second compartments, wherein only one perforation tab (11) is arranged at each of the crests or troughs such that the sole attachment between the first and second compartments is achieved through connection of the perforation tabs at the crests and troughs (Fig 11). PNG media_image1.png 757 826 media_image1.png Greyscale Regarding claim 2, Davey further discloses bending the compartments relative to one another can cause them to snap and break the tab forming the connection between compartments since it has the structure as recited. Regarding claim 3, Davey further discloses the compartments (2a, 2b) shaped as a polygon (Fig 1). Regarding claim 6, Davey further discloses at least four sets of undulating crests and troughs (Fig 21). Regarding claim 7, Davey further discloses at least five sets of undulating crests and troughs (Fig 21). Regarding claim 10, Davey further discloses wave-shaped perforation region (8) having a wave thickness greater than tab thickness of each of the tabs (11) since the tabs are located within the perforation region (Fig 21). Regarding claim 13, Davey further discloses the tray composed of polypropylene (€0020). Regarding claim 14, Davey further discloses first and second compartments (2a, 2b) comprising first and second flanges (7a, 7b). Regarding claim 15, Davey further discloses first flange (7a) comprising first terminal edge (8) and second flange comprising second terminal edge (8). Regarding claim 16, Davey further discloses first terminal edge (8) adjacent to second terminal edge (Fig 1). 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. Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Davey in view of US Patent No. 5,938,068 to Atkins et al. (Atkins) or EP 1092344 to Fernholz. Regarding claim 11, Davey teaches the tray of claim 1 but does not teach the wave-shaped perforation substantially sinusoidal. However, Atkins discloses a multi-compartment container (Fig 1) comprising compartments (10, 12) separated by a perforation (16) that is substantially sinusoidal with crests and troughs (col. 2, ll. 10-20). Fernholz also discloses a multi-compartment container (Fig 1) where the compartments (2) are separated by a sinusoidal perforation (8) that facilitate separation of the container so that each compartment can be used as a separate sale unit (¶0014). One of ordinary skill in the art would have found it obvious to make the perforation region (8) of Davey also sinusoidal as suggested by either Atkins or Fernholz in order to facilitate separation of the compartments. Claim(s) 17-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Davey in view of US 2007/0228039 to Tyberghein. Regarding claim 17, Davey teaches the tray of claim 15 but does not explicitly teach first and second terminal edge separated by a gap. However, Tyberghein discloses a multi-compartment tray (10, Fig 1) and in particular discloses the trays having first and second terminal edges separated by a gap (101B, Fig 9). One of ordinary skill in the art would have found it obvious to incorporate gaps between the terminal edges of each compartment as suggested by Tyberghein in order to facilitate separation. Regarding claim 18, the modified Davey further teaches gap (101b, Tyberghein) is notched (Fig 9).
