DETAILED ACTION
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 4-7, 9-13 and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application No. 2013/0236626 (BRACKENRIDGE).

As to claims 1 and 20, BRACKENRIDGE teaches mixing vegetable oil [0016]; starch n-octenyl succinic anhydride modified starch; methylcellulose [0015], [0021], water [0019], vegetable protein [0010] and binder in the form of a starch, such as waxy maize starch. In the Examples, the vegetable fat is added in amounts of 15-35% [0019]. This overlaps the claimed range. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990) (The prior art taught carbon monoxide concentrations of "about 1-5%" while the claim was limited to "more than 5%." The court held that "about 1-5%" allowed for concentrations slightly above 5% thus the ranges overlapped.); In re Geisler, 116 F.3d 1465, 1469-71, 43 USPQ2d 1362, 1365-66 (Fed. Cir. 1997). Moreover, it would have been obvious to one of ordinary skill in the art to select any portions of the disclosed ranges including the instantly claimed ranges from the ranges disclosed in the prior art references, particularly in view of the fact that; "The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set percentage ranges is the optimum combination of percentages" In re Peterson 65 USPQ2d 1379 (CAFC 2003). Also In re Malagari, 182 USPQ 549,533 (CCPA 1974) and MPEP 2144.05.
In the Veggy Burger example [0021], [0022], BRACKENRIDGE teaches adding soy flour with water, then adding wheat gluten (i.e., a protein), fat mimetic, the soy flour mixture and methylcellulose to a mixer. Additional water and dry ingredients can be also be added in a next step. However, it would have been obvious to vary when the ingredients are added to maximize mixing. The specification also does not provide any evidence that the order in which the ingredients are added. A number of examples are provided beginning on page 15 but none of the examples show that the manner in which the ingredients are mixed are critical. See also, Ex parte Rubin, 128 USPQ 440 (Bd. App. 1959) (Prior art reference disclosing a process of making a laminated sheet wherein a base sheet is first coated with a metallic film and thereafter impregnated with a thermosetting material was held to render prima facie obvious claims directed to a process of making a laminated sheet by reversing the order of the prior art process steps.). See also In re Burhans, 154 F.2d 690, 69 USPQ 330 (CCPA 1946) (selection of any order of performing process steps is prima facie obvious in the absence of new or unexpected results); In re Gibson, 39 F.2d 975, 5 USPQ 230 (CCPA 1930) (Selection of any order of mixing ingredients is prima facie obvious.).

In [0012], it is taught that corn and tapioca starch can be added. That starch can be modified [0014]. The modified starch exhibits an increase in stability against heat, acids, or freezing, improved texture, increase or decrease viscosity, increase or decrease gelatinization times, and increase or decrease solubility. It would have been obvious to modify the starches as it is taught that the modified starches increase stability and other properties of the product.

As to claims 10 and 11, BRACKENBRIDGE teaches that starches [0014] can be added to increase the stability, texture and viscosity of products. In [0015], hydrocolloids such as methylcellulose are added to vary the viscosity. It would have been obvious to vary the amount of starches and hydrocolloids relative to the oil based on the desired stability, texture and viscosity of the product. Moreover, Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (Claimed process which was performed at a temperature between 40°C and 80°C and an acid concentration between 25% and 70% was held to be prima facie obvious over a reference process which differed from the claims only in that the reference process was performed at a temperature of 100°C and an acid concentration of 10%.); see also Peterson, 315 F.3d at 1330, 65 USPQ2d at 1382 ("The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set of percentage ranges is the optimum combination of percentages."); In re Hoeschele, 406 F.2d 1403, 160 USPQ 809 (CCPA 1969) (Claimed elastomeric polyurethanes which fell within the broad scope of the references were held to be unpatentable thereover because, among other reasons, there was no evidence of the criticality of the claimed ranges of molecular weight or molar proportions.). For more recent cases applying this principle, see Merck & Co. Inc. v. Biocraft Lab. Inc., 874 F.2d 804, 10 USPQ2d 1843 (Fed. Cir.), cert. denied, 493 U.S. 975 (1989); In re Kulling, 897 F.2d 1147, 14 USPQ2d 1056 (Fed. Cir. 1990); and In re Geisler, 116 F.3d 1465, 43 USPQ2d 1362 (Fed. Cir. 1997); Smith v. Nichols, 88 U.S. 112, 118-19 (1874) (a change in form, proportions, or degree "will not sustain a patent"); In re Williams, 36 F.2d 436, 438 (CCPA 1929) ("It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions."). See also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007) (identifying "the need for caution in granting a patent based on the combination of elements found in the prior art.").

The waxy maize starch can be added [0013] and can be modified to increase stabilization [0014]. It would have been obvious to use a stabilized and waxy maize starch cross-linked for greater stabilization, as BRACKENRIDGE teaches one skilled in the art to provide a stabilized, modified starch.
Claims 2 and 3 are rejected under 35 U.S.C. 103 as being unpatentable over BRACKENRIDGE as applied to claim 1 above, and further in view of United States Patent Application Publication No. 2020029590 (NURMI).

The Veggy Burger [0021]-[0022] can be cooked [0022]. Modified starch is added to provide a starch with increase stability against heat, acids, or freezing, improved texture, increase or decrease viscosity, increase or decrease gelatinization times, and increase or decrease solubility, among others. [0014]. However, BRACKENRIDGE is silent as to freezing and reheating the product.
NURMI teaches consumers want a meat analogue product that can be frozen before cooking and remain heat stable [025] and [0136]. The product can be microwaved, fried, grilled or cooked and the product does not melt when fried on a hot fry-pan or a grill or when heated with microwaves [0025] and [0136].
It would have been obvious to one skilled in the art to freeze and reheat the product before consumption given NURMI teaches consumers want a meat analogue product that can be frozen before cooking and remain heat stable [025] and [0136].
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over BRACKENRIDGE as applied to claim 1 above, and further in view of United States Patent Application Publication No. 2011/0151097 (TUASON)

BRACKENRIDGE teaches the use of modified starches [0014] but silent as hydroxypropyl distarch phosphate modified starch.
TUASON teaches that hydroxypropyl distarch phosphate is a preferred starch [0029] for increasing the stability of food products [0029]. Thus, it would have been obvious to one skilled to add hydroxypropyl distarch phosphate modified starch to BRACKENRIDGE, as it is taught that the starch increases the stability of food products.
Claims 14-15 are rejected under 35 U.S.C. 103 as being unpatentable over BRACKENRIDGE as applied to claim 1 above, and further in view of WO2021078708 (VAN LEEUWEN).

As to claims 14-15, BRACKENRDIGE teaches the addition of protein [0010] but silent as to adding textured protein itself.
VAN LEEWUN teaches at pg. 22, lines 20-25 that texturized vegetable protein adds to the cohesiveness and eating quality of vegetable protein products. The texturized plant protein can be soy or pea )pg. 22, lines 4-10.
It would have been obvious for one skilled in the art to add texturized vegetable protein to the product of BRACKENRIDGE to enhance the cohesiveness and eating quality of the resulting product.
