Office Action

§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 . Status of Application Claims 28-38 and 42-53, 56 are pending. Claims 45-48 are withdrawn from consideration. Claims 28-38, 42-44, 49-53, 56 are under consideration. 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 12/29/2025 has been entered. Claim Rejections - 35 USC § 103 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. Claims 28-29, 31-38, 42-44, 49-53, 55 are rejected under 35 U.S.C. 103 as being unpatentable over United States Patent Application Publication No. 2007/0148305 (SHERWOOD). PNG media_image1.png 199 616 media_image1.png Greyscale SHERWOOD teaches a protein/beverage drink [0039]. The drink can be packaged in cans [0096]. The total amount of protein ranges from 0.01 to 15% [0039]. The protein is a caseinate free protein based on whey type proteins [0040]. The whey type protein may include several protein fractions, including, for example, β-lactoglobulin [0007]. It would have been obvious to one skilled in the art to use β-lactoglobulin as the protein. The pH is 2 to 5.5 [0065]. 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. As to the viscosity, it is taught that thickening of the beverage is undesirable [0055]. It would have been obvious to limit the viscosity as a thick drink is discouraged. Moreover, applicant has chosen to use parameters that cannot be measured by the Office, for the purpose of prior art comparison, because the office is not equipped to manufacture prior art products and compare them for patentability. Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977). "When the PTO shows a sound basis for believing that the products of the applicant and the prior art are the same, the applicant has the burden of showing that they are not." In re Spada, 911F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). Therefore, as a prima facia case of obviousness has been properly established, the burden is shifted to the applicant to show that the prior art product is different. PNG media_image2.png 54 602 media_image2.png Greyscale The beverage can be pasteurized [0095]. PNG media_image3.png 64 601 media_image3.png Greyscale As to claim 30, it is taught that the beverage itself can be pasteurized [0095] and can be placed in sterile cans [0027] with sterile ingredients [0065]. It would have been obvious to one skilled in the art to provide a sterile preparation. PNG media_image4.png 76 589 media_image4.png Greyscale PNG media_image5.png 95 599 media_image5.png Greyscale As to claims 31-32, the intrinsic tryptophan is defined as measuring protein nativity (see [0170] - [0171] in the published version of this specification). In particular, the degree of protein nativeness depends on a number of factors including protein concentration, pH, temperature and time of heat treatment. As to the protein fraction and beverage of the present invention, applicant heats the BLG protein at a temperature of 70-82°C (see [0354] published version of this specification). The pH ranges from 3.0 to 4.7 (see [0190] to [0194] of the published version of this specification). As SHERWOOD teaches the same protein concentration (0.01 to 15% [0039]), pH (i.e., 2 to 5.5 [0065]) and temperature (i.e., 140o – 188oF at [0065], it considered that the beverage would the same intrinsic tryptophan fluorescence emission ratio. PNG media_image6.png 67 629 media_image6.png Greyscale PNG media_image7.png 87 594 media_image7.png Greyscale As to claims 33-34, SHERWOOD does not teach denaturing the protein. PNG media_image8.png 54 595 media_image8.png Greyscale The pH is 2 to 5.5 [0065]. This encompasses the claimed range. PNG media_image9.png 144 631 media_image9.png Greyscale PNG media_image10.png 173 635 media_image10.png Greyscale As to claims 36-37, coloring agents can be added [0061]. It would have been obvious to vary the color based on the desired appearance of the beverage. It is noted that the Patent Office does not have the facilities for determining the CIELAB color scale . In this regard, applicant has chosen to use parameters that cannot be measured by the Office, for the purpose of prior art comparison, because the office is not equipped to manufacture prior art products and compare them for patentability. Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977). "When the PTO shows a sound basis for believing that the products of the applicant and the prior art are the same, the applicant has the burden of showing that they are not." In re Spada, 911F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). Therefore, as a prima facia case of obviousness has been properly established, the burden is shifted to the applicant to show that the prior art product is different. PNG media_image11.png 83 612 media_image11.png Greyscale Magnesium can be added [0114]. In claim 27 of SHERWOOD, a magnesium-containing compounds be present in an amounts of 0.1 to 2.0%. However, SHERWOOD also teaches that the magnesium can be added to form specialized products [0114]. It would have been one skilled in the art to vary the amount of magnesium based on the type of specialized product produced. PNG media_image12.png 222 576 media_image12.png Greyscale PNG media_image13.png 61 616 media_image13.png Greyscale PNG media_image14.png 506 651 media_image14.png Greyscale As to claims 42-44 and 49-52, SHERWOOD teaches a protein/beverage drink [0039]. The proteins include whey type proteins, including β-lactoglobulin [0007]. It would have been obvious to one skilled in the art to use β-lactoglobulin as the protein. The drink can be packaged in cans [0096]. The total amount of protein ranges from 0.01 to 15% [0039]. SHERWOOD does not require specific amounts of other of types of proteins. PNG media_image15.png 70 572 media_image15.png Greyscale As to claim 53, SHERWOOD lowering the pH of the aqueous whey protein prior to addition to the beverage composition results in a carbonated protein beverage with superior organoleptic properties, by preventing or at least greatly reducing precipitation and gelling of the protein as it passes through the zone of isoelectric points [0045]. In this regard, it would have been obvious to limit the amount of insoluble material (i.e., keep it at most 15% insoluble matter). PNG media_image16.png 67 640 media_image16.png Greyscale As to the turbidity, the turbidity can range from clear [0055] to turbid formulations [0091]. In [0091], it is also taught that the turbidity can be varied during processing. Thus, it would have been obvious to one skilled in the art to vary the turbidity of the drink based on the desired appearance of the drink. Response to Arguments Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
