Office Action

§103 §112
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 Specification The following guidelines illustrate the preferred layout for the specification of a utility application. These guidelines are suggested for the applicant’s use. Arrangement of the Specification As provided in 37 CFR 1.77(b), the specification of a utility application should include the following sections in order. Each of the lettered items should appear in upper case, without underlining or bold type, as a section heading. If no text follows the section heading, the phrase “Not Applicable” should follow the section heading: (a) TITLE OF THE INVENTION. (b) CROSS-REFERENCE TO RELATED APPLICATIONS. (c) STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT. (d) THE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT. (e) INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A READ-ONLY OPTICAL DISC, AS A TEXT FILE OR AN XML FILE VIA THE PATENT ELECTRONIC SYSTEM. (f) STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR OR A JOINT INVENTOR. (g) BACKGROUND OF THE INVENTION. (1) Field of the Invention. (2) Description of Related Art including information disclosed under 37 CFR 1.97 and 1.98. (h) BRIEF SUMMARY OF THE INVENTION. (i) BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S). (j) DETAILED DESCRIPTION OF THE INVENTION. (k) CLAIM OR CLAIMS (commencing on a separate sheet). (l) ABSTRACT OF THE DISCLOSURE (commencing on a separate sheet). (m) SEQUENCE LISTING. (See MPEP § 2422.03 and 37 CFR 1.821 - 1.825). A “Sequence Listing” is required on paper if the application discloses a nucleotide or amino acid sequence as defined in 37 CFR 1.821(a) and if the required “Sequence Listing” is not submitted as an electronic document either on read-only optical disc or as a text file via the patent electronic system. When there are drawings, there shall be a “brief description of the several views of the drawings” (See 37 C.F.R. 1.74.). The section heading “brief description of the several views of the drawings” as set forth in 37 C.F.R. 1.74 is missing. The language is not the same as set forth above. Please correct. The disclosure is objected to because of the following informalities: there is an extra bracket at page 3, line 14. PNG media_image1.png 110 574 media_image1.png Greyscale Appropriate correction is required. The disclosure is objected to because of the following informalities: there is blurry shading and text page 30, line 29. PNG media_image2.png 156 284 media_image2.png Greyscale Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 1-15 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The phrase “%” in claims 1, line 5 is vague and indefinite as it is unclear whether the % is weight or volume %. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 2 recites the broad recitation “60:40 to about 95:5”, and the claim also recites “70:30 to about 80:20” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 3 recites the limitation "the source of plant protein" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the at least one source of plant protein". The abbreviations in claim 3 are vague and indefinite. Please set forth the unabbreviated text in the first instance. Claim 4 recites the limitation "the source of animal protein" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the at least one source of animal protein". The abbreviations SPI and BT in claim 5 are vague and indefinite. Please set forth the unabbreviated text in the first instance. Claim 5 recites the limitation "SPI" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the SPI". Claim 5 recites the limitation "BT" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the BT". The abbreviations SPI and PPC in claim 7 are vague and indefinite. Please set forth the unabbreviated text in the first instance. Claim 7 recites the limitation "SPI" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the SPI". Claim 7 recites the limitation "PPC" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the PPC". The abbreviations SPI, PPC and MPC in claim 8 are vague and indefinite. Please set forth the unabbreviated text in the first instance. Claim 8 recites the limitation "SPI" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the SPI". Claim 8 recites the limitation "PPC" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the PPC". Claim 8 recites the limitation "MPC" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the MPC". Claim 9 recites the limitation "step (b)" in lines 2-3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the step (b)" and in claim 1 refer to “steps …”. Claim 10 recites the limitation "step (b)" in line 2. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the step (b)" and in claim 1 refer to “steps …”. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 11 recites the broad recitation “60 to about 80° C”, and the claim also recites “65 to about 75° C, more preferably about 70° C” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 12 recites the limitation "the vessel contents" in lines 3-4. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider earlier stating "vessel contents". Claim 13 recites the limitation "agitator arms" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the one or more agitator arms". A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 14 recites the broad recitation “50 to about 100× faster”, and the claim also recites “80× faster” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 15 recites the limitation "the temperature, moisture and shear conditions" in line 2. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider earlier stating "temperature, moisture and shear conditions". Claim 15 recites the limitation "step (c)" in line 3. There is insufficient antecedent basis for this limitation in the claim. Applicant is advised to consider stating "the step (c)" and in claim 1 refer to “steps …”. The phrase “the proteins fibers” is vague and indefinite as it is unclear whether this plant protein or animal protein or both. Furthermore, the language does not appear to be grammatically correct as the term “proteins” is not written as being possessive like “proteins’” or “protein’s’”. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 20 recites the broad recitation “greater than about 0.4”, and the claim also recites “about 0.6 to about 0.8” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Clarification and/or correction required. 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. Claim(s) 1, 3-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Klossner et al. (US 6,017,576). Regarding claim 1, Klossner (‘576) teaches a method for producing a texturised hybrid meat analogue, the method comprising: (a) combining at least one source of plant protein and at least one source of animal protein with water to form a protein composition with a moisture content of about 40 to about 70%, (b) injecting high pressure steam into the protein composition in a sealed vessel while applying shear, (c) continuing to apply shear to the protein composition in the sealed vessel for about 5 to about 45 minutes while maintaining the temperature and moisture of the composition, (d) allowing the protein composition to cool, to provide a texturised hybrid meat analogue (See Abs., col. 8, Example 1, FIG-1, claims 1-5.), however, fails to expressly disclose until the protein composition reaches about 120 to about 150° C. Applicant does not set forth any non-obvious unexpected results for the protein composition being at any specific temperature.
