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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 2/18/2026 has been entered.
Response to Arguments
Applicant's arguments filed 2/18/2026 have been fully considered but they are not persuasive. Applicants continue to urge that Adams et al. do not teach or suggest the claimed average surface extension ratio in the range of 1.5 to 3. In response, Applicant’s arguments are not found persuasive because the claimed property can be calculated from the same parameters as claimed and taught by Adams et al. Beginning on page 18,ln30, Adams et al. teach that their dimensions are in each of the x, y, and z planes and because one of ordinary skill understands the surface area of any 3D object is the area of each face of the 3D object added together, and since Adams is teaching the same lengths, widths, and heights as is required in the dependent claims, PHOSITA would reasonably arrive at the claimed extension surface area ratio of claim 1. It is the Examiner’s position that one of ordinary skill can arrive at the claimed ratio with the extension amounts taught by Adams et al. pages 18,ln.29 to page 19,ln.24 to achieve a more flexible effective washing pod.
Further supporting Examiner’s position is that Adams et al. teach a multicompartment unit dose watersoluble article having 0.1 to 3 mm sealing width between the 3 compartments. See page 6, ln.10-12 which meets the required average sealing width of instant claim 6.
Adams et al. teach each compartment has a maximum depth of from 5 to 40 mm. See page 6,ln.15 and page 7,ln.1-2.
Adams et al. teach the largest height of the compartments range from 5-40mm which encompasses the ratio of claim 9. See page 14,ln.10.
And Adams et al. teach limitation to the largest dimension on page 14, ln.5-20 teaching height, width and length of the capsule within the claimed range of 10-60 mm encompassing the instant claim 10 and thus, arguments that the claimed extension ratio is not taught is not found persuasive because one of ordinary skill is reasonably apprised to arrive at the same calculation of extension surface ratio, with the prior art teaching the same parameters for length, width and height.
Accordingly, the rejection is maintained below.
Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claim(s) 1-14 are rejected under 35 U.S.C. 103 as obvious Adams et al. (EP 19200470) pdf attached.
Adams et al. (EP 19200470) also has US Pub No: 2022/0325210 A1, however, the EP document is referenced below for the prior art date.
With respect to claim 1, Adams et al. teach a unit dose dishwasher capsule for treatment of dishes, the capsule comprising three compartments (see figure 1 and 2B) that are sealed with the same or different products from granular, liquids gels or powders and the capsules are made of polyvinyl alcohol water soluble films. See page 14,ln.6 encompassing claim 1 language to containing a substrate treatment composition. Also see page 1, lines 5-15 describing multi - compartment water - soluble detergent capsules are typically made with water - soluble film, for example polyvinyl alcohol. The preferred capsule manufacturing process involves thermoforming the film. Thermoforming is a process in which a first sheet of film is subjected to a moulding process to form recesses in the film. The process involves heating the film to soften it, and then applying vacuum to hold the film in the moulds. The recesses are then filled.
Claim 1 limitation to the capsule is formed from two sheets of water-soluble film, the two sheets of film being sealed together forming a sealing web lying on a sealing plane, the sealing web comprising a peripheral sealing skirt, inter-compartment sealing webs between compartments thereby separating the compartments from one another and a central sealing web is read upon by Adams et al. teaching the capsules are completed by overlaying a second sheet over the filled recesses and sealing it to the first sheet of film around the edges of the recesses to form a flat sealing web. See page 1,ln.5-16. Each of the three compartments is formed as described on page 4,ln.1-10, teaching sealing a second sheet of film to the first sheet of film across the formed recesses to produce a capsule having three compartments separated from each other by a continuous internal sealing web; See also the Figure 2E, items 22, 25 encompassin the peripheral sealing skirt, and items 22 and 23 encompassing language to an intercompartment sealing web.
Adams et al. do not explicitly teach wherein the compartments have an average surface extention ratio in the range of 1.5 to 3, the surface extension ratio is a surface area of the film above the sealing plane to a surface area of a footprint of the three compartments located in the sealing plane as required by claim 1.
Adams et al. is considered to be analogous to the claimed invention as being in the same field of a unit dose having 3 compartments formed from a watersoluble film.
It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to arrive at the claimed surface extension ratio in the range of 1.5 to 3 as required in claim 1 because Adams et al. teach a PVA water soluble capsule having length, width, and height dimensions within the claimed ranges and ratios and further teach extension values wherein each compartment extends above and below the sealing plane to form a flexible capsule that takes up less volume in a package. It is the Examiner’s position that one of ordinary skill can arrive at the claimed ratio with the extension amounts taught by Adams et al. pages 18,ln.29 to page 19,ln.24 to achieve a more flexible effective washing pod. One of ordinary skill is motivated to optimize the parameters as claimed because Adams et al. teach the claimed surface extension amounts yields a flexible and effective cleaning capsule and teach any variations are discretionary.
With respect to the general shape and footprints, limitations to the compartments being arranged radially, planar symmetry, width, volume, height, etc, of claims 2-4, is met by the art teaching discretion in the shape of the compartments. See page 17,ln.4 teaching various polygonal shapes composed of curved or straight lines or combinations thereof. See also page 23,ln.5-10 guiding one of ordinary skill to modifications. Regarding the identical shape of the footprint of the compartments required by claim 5, Adams et al. teach the identical shape is achieved by use of a semi - circular mould cross - section for the compartment. These circular moulds also encompass the radial arrangement of claim 2. The relaxation of the formed capsule once it has been removed from the mould can change the compartment, for example, change a semi - ovaloid cross - section to be nearer to a fully ovaloid cross - section which remains substantially uniform because the relaxation is substantially uniform. The compartments can be generally polygonal in plane view. These shapes (whether identical or varying) are achieved by use of various mould cross - sections for each compartment. See page 5,ln.20-page 6.
Adams et al. teach multicompartment unit dose watersoluble article have width sufficient to ensure sealing between the 3 compartments, from 0.1 to 3 mm. See page 6, ln.10-12 meeting the range of claim 6.
Claims 4 and 7 are met Adams et al. teaching preferably, the third compartment is larger than each of the first and second compartments and each compartment has a maximum depth of from 5 to 40 mm , more preferred from 8 to 30 mm , most preferred from 9 to 20 mm. See page 6,ln.15 and page 7,ln.1-2.
Adams et al. teach the height of the compartments range from 5-40mm which encompasses the ratio of claim 9. See page 14,ln.10.
Claim 10 limitation to the largest dimension is taught on page 14, ln.5-20 teaching height, width and length of the capsule within the claimed range of 10-60 mm.
Regarding the volume of claims 11-13, page 20,ln.5-30 teach an embodiment wherein each compartment is configured to hold more than another compartment and an embodiment where 2 compartments hold a substantially equal amount. The volume of the third compartment 13 is such that the weight of the powder compound is at least 7 grams, preferable 10 grams. Each liquid compound weighs substantially at least 1.5 grams , preferable 2.7 grams .By having the liquid compound a medium weight , that is , a weight above approximately 2 grams which difference in volumes encompasses the claim 13 ratio of 0.1 to 2.5 times.
Regarding the method of claim 14, see pages 3-4 describing the thermoforming process including the a ) placing a first sheet of water - soluble polyvinyl alcohol film over a mould comprising cavities;
( b ) heating and applying vacuum to the film to mould the film into the cavities and hold it in place to form corresponding recesses in the film;
( c ) filling the different parts of a detergent composition, each of which may have a different colour / opacity (as well as different treatment function) into the recesses, the parts together forming a full detergent composition;
( d ) sealing a second sheet of film to the first sheet of film across the formed recesses to produce a capsule having three compartments separated from each other by a continuous internal sealing web;
( e ) cutting between the capsules so that a series of capsules with three compartments are formed , each capsule containing a part of a detergent composition in three compartments (e.g. , one larger - sized compartment and two relatively medium - sized compartments).
Limitation to the compartments having surface extension ratio in the range of 1.6 to 3 as required in claim 1 and 14 is met by Adams et al. teaching their multicompartment unit dose watersoluble article wherein each compartment extends above (page 19,ln.5) and below the sealing plane (page 19,ln.10-15) to form a compact and stable separation of the interior of compartments and results in a flexible capsule that takes up less volume in a package. See page 20,ln.30-page 21,ln.2. See also pages 18,ln.29 to page 19,ln.24. Adams et al. teach that each Adams et al. teach each of the first compartment 11 , the second compartment 12 , and the third compartment 13 extends above the sealing plane such that the part of each compartment that is furthermost from the sealing plane, in a direction perpendicular to the sealing plane is referred to herein as the first distance ( d1 ), the second distance ( d2 ), and the third distance ( d3 ), respectively; wherein d1 is less than or equal to 20 mm , is less than or equal to 12 mm , or is less than or equal to 8 mm ; d2 is less than or equal to 20 mm , is less than or equal to 12 mm , or is less than or equal to 8 mm ; and d3 is is less than or equal to 40 mm , is less than or equal to 30 mm , is less than or equal to 20 mm , or is less than or equal to 12 mm. Each of the three compartments 11, 12, 13 extends below the sealing plane such that the part of each compartment that is furthermost from the sealing plane, in a direction perpendicular to the sealing plane is referred to herein as the fourth distance (d4), wherein d4 is 5-9 mm. (See page 19, ln.5-15).
