DETAILED ACTION
Response to Arguments
1. Applicant's arguments filed April 13, 2026 have been fully considered but they are not persuasive.
Applicant argues that a person of ordinary skill in the art would not have been motivated to combine Dayton and Pierce.
Examiner notes the modification of Dayton in view of Pierce is to provide a container having a conical sidewall, like that well know of paper drinking cups. Pierce teaches it is known to match the draft angle of the closure wall with that of the container side wall (see para. [0008]). While Examiner acknowledges Applicant’s argument that their angle is based on achieving a high-friction seal specifically with high-fiber based materials, the MPEP is clear that obviousness can be found for differing reasons. See MPEP 2114(IV): “Rationale Different From Applicant’s Is Permissible.” That Applicant’s goal is to increase friction for use with a specific type of paper does not preclude a finding of obviousness where a person of ordinary skill in the art would match the draft angle of the closure and container when modifying Datyon to provide a conical, cup-like body like that of Pierce. Moreover, regarding the result-effective variable, the analysis is made within this differing context of providing a cup, and arriving at an optimal sidewall angle, e.g. for gripping by a user, not for configuring the frictional force between paper components, as is Applicant’s purpose.
Claim Rejections - 35 USC § 103
2. 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.
3. Claims 1-3, 7, and 21 are rejected under 35 U.S.C. 103 as being unpatentable over US 2010/0084361 (Dayton) in view of US 2007/0181591 (Pierce).
Regarding claim 1, Dayton teaches a closure element (120) adapted for use with a cup (104) having a top opening (unlabeled; clearly seen in Figure 1A defined by the rim of the container, and mentioned at least in para. [0013] as “an opening of the paper container”) with a first area A1 in a cross-sectional plane perpendicular to an axis A (A1 is defined by the opening diameter of container 104),
said closure element and cup adapted to form a container (100; see Figure 1B and para. [0077]) when combined, said container extending along said axis A (a vertical axis of symmetry is not shown, but is inherently present) and configured to hold a beverage or granular substance (see para. [0077] describing the container being for the storage and transport of “water, beverages, and the like”),
said closure element comprising:
a sealing portion (unlabeled; read as the surface where 102 points in Figure 1A) with a second area A2 in a cross-sectional plane perpendicular to said axis A (defined by the container diameter), wherein the second area A2 is essentially equal to said first area A1 (the areas are essentially the same in that they comprise substantially the same diameter as seen in Figure 1A);
an annular sealing wall (108) extending around said sealing portion (see 108 depending from a periphery of 102 in Figure 1A), wherein said annular sealing wall is tilted with an angle alpha (a) in relation to said axis A and intended to be in contact with an inside surface of an annular inner wall of said cup to seal said container (not taught); and
said closure element further comprises a spout (112) configured to deliver said beverage or granular substance to a user (connected to the opening at 120 in Figure 1A);
wherein said closure element is configured to be pressed into said cup so that said annular sealing wall engages said inside surface of said annular inner wall of said cup to form a tight seal between said closure element and said cup (108 taught to be inserted into the container 104 to mate with a similar feature 110; para. [0077] teaches the connection could comprise a friction fit),
wherein said angle alpha is between 2-8 degrees (not taught),
wherein said closure element is made of molded paper pulp, comprising cellulose-based paper material or fiber-based paper material (102 taught to be formed of paper pulp in para. [0077]).
Dayton as applied above fails to teach that the annular sealing wall is tilted with an angle alpha (a) in relation to said axis A and intended to be in contact with an inside surface of an annular inner wall of said cup to seal said container; … wherein said angle alpha is between 2-8 degrees.
Examiner notes Dayton teaches in para. [0077] that the lower section “may be conical” in an embodiment.
Pierce, analogous to paper containers, teaches it is known to form a container in a conical shape (noting the draft angle of the wall in para. [0008]) and forming the annular sealing wall of the lid with a matching angle resulting in a larger sealing area (para. [0008]; Figures 4 and 5).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the container of Dayton, forming it in a conical shape as taught therein, and modifying the closure element annular sealing wall, forming it to have a matching conical angle as taught by Pierce, motivated by the benefit of increasing the sealing surface area, having a predictable outcome absent a teaching of an unexpected result. See KSR International Co. v. Teleflex Inc. et al. No. 04-1350, 550 U.S. 2007 at 13, lines 22-25 which states, “When a work is available in one field of endeavor, design incentives ...can prompt variations of it, either in the same field or a different one. Furthermore, see id. at 13, lines 27-31 which states “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious”.
It would have been further obvious to form the size of the angle of the of the sealing wall and container wall to matching angles between 2-8 degrees, motivated by design choice, having a predictable outcome absent a teaching of an unexpected result. It has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Further, a change in size, absent a teaching of an unexpected result, is within ordinary skill in the art. See MPEP 2144.04(IV)(A):
In re Rose, 220 F.2d 459, 105 USPQ 237 (CCPA 1955) (Claims directed to a lumber package “of appreciable size and weight requiring handling by a lift truck” where held unpatentable over prior art lumber packages which could be lifted by hand because limitations relating to the size of the package were not sufficient to patentably distinguish over the prior art.); In re Rinehart, 531 F.2d 1048, 189 USPQ 143 (CCPA 1976) (“mere scaling up of a prior art process capable of being scaled up, if such were the case, would not establish patentability in a claim to an old process so scaled.” 531 F.2d at 1053, 189 USPQ at 148.).

Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device.
Regarding claim 2, further comprising a removable and attachable lid element (Dayton 114) arranged to cover said spout (see Dayton para. [0077]), and said lid element and spout are adapted to seal the container when the lid element is arranged to cover said spout, such that spilling from the container is essentially prevented (see fully sealed container in Dayton Figure 1B).
Regarding claim 3, said spout comprises a first set of threads extending around said spout (112 is taught to be threaded in Dayton para. [0077] and shown as such in Figure 1A), and wherein said lid element comprises a second set of threads and wherein said lid element is configured to be screwed onto said spout (114 is taught to be a “screw cap assembly” and has mating threads in Dayton para. [0077]).
Regarding claim 7, Dayton teaches a container (Dayton 104) configured to hold a beverage or granular substance (see Dayton para. [0077] describing the container being for the storage and transport of “water, beverages, and the like”) and extending along an axis A (unlabeled but inherently present vertical axis of symmetry), the container comprising:
a first cup (104) made of cellulose-based paper material or fiber-based paper material (102 taught to be formed of paper pulp Dayton in para. [0077]), said cup comprising an opening with a first area A1 in a cross-sectional plane perpendicular to an axis A (see unlabeled opening defined by the container rim in Figure 1A), wherein said cup comprises an inner annular wall tilted at said an angle alpha (a) in relation to said axis A (Dayton teaches the container can be conical in para. [0077]), and a closure element according to any previous claim (see the rejection of claim 1 above).
Regarding claim 21, at least an inside surface of the closure device comprises an impermeable coating layer (see “waterproof and biodegradable coating” in Dayton para. [0010]).

Regarding claim 6, Dayton in view of Pierce as applied above fails to teach that said lid element comprises a spike configured to be used to pierce a permeable surface of said spout in order to allow a user to reach said beverage or granular substance.
Lehmkuhl, analogous to spouts sealed by a cap, teaches it is known to provide a foil seal (90) to be pierced by a spike in order to dispense the container contents (col. 2, line 65 through col. 3, line 7).

Chung, analogous to molded paper containers, teaches forming the container of a slurry comprising a strength additive (inorganic salt; para. [0065]) in the range of 1.5%-4% (preferably 1.5%-5%, most preferably about 4%; see para. [0065]).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the container of Dayton in view of Pierce, forming the container of paper pulp slurry comprising a strength additive in the range of 1.5%-4% as taught by Chung, motivated by the use of a sufficiently strong paper molding material, having a predictable outcome absent a teaching of an unexpected result. See KSR International Co. v. Teleflex Inc. et al. No. 04-1350, 550 U.S. 2007 at 13, lines 22-25 which states, “When a work is available in one field of endeavor, design incentives ...can prompt variations of it, either in the same field or a different one. Furthermore, see id. at 13, lines 27-31 which states “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious”.
