Claims Claims 1, 6, 31, 34, 36 and 38 are pending. WITHDRAWN OBJECTIONS All objections of record in the Office Action mailed 11/18/2025 have been withdrawn due to Applicant’s amendments in the Paper filed 6/22/2026. WITHDRAWN REJECTIONS All rejections of record in the Office Action mailed 11/18/2025 have been withdrawn due to Applicant’s amendments in the Paper filed 6/22/2026. NEW OBJECTIONS The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Official Correspondence. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: The phrases “the amount of oleic acid … monoacylglyceride” in claim 1, lines 6-11, “about 5% … triacylglyceride form” in claim 34, line 13 “the amount of oleic acid … monoacylglyceride” in claim 34, lines 6-10, “about 5% … triacylglyceride form” in claim 34, line 12 and “about 5% diacylglyceride form in claim 38, lines 2-3 are not described in the text of the Specification. Applicant is advised to consider amending the text of the Specification to incorporate this language while being careful not to add new matter. Claim Objections Claim 1 is objected to because of the following informalities: the term “esterfied” in line 10 is a typo and should state “esterified”. Appropriate correction is required. Claim 1 is objected to because of the following informalities: the term “esterfied” in line 13 is a typo and should state “esterified”. Appropriate correction is required. Claim 34 is objected to because of the following informalities: the term “esterfied” in line 10 is a typo and should state “esterified”. Appropriate correction is required. Claim 34 is objected to because of the following informalities: the term “esterfied” in line 12 is a typo and should state “esterified”. Appropriate correction is required.

The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The phrase “about 30% or more of the fatty acid content is esterfied in monoacylglyceride form” in claim 1, lines 10-11 is new matter. Fatty acids, like oleic acid, are NOT esters. PNG media_image1.png 148 606 media_image1.png Greyscale A monoacylglyceride (or monoglyceride) is an ester, not an acid. PNG media_image2.png 136 682 media_image2.png Greyscale Paragraph [00106] of the Specification refers to “MAG content” and not “fatty acid content”. PNG media_image3.png 58 636 media_image3.png Greyscale Paragraph [00106] may provide support for MAG content but not fatty acid content. The phrase “about 5% or less of the fatty acid content is esterfied in triacylglyceride form” in claim 1, line 13 is new matter. Fatty acids, like oleic acid, are NOT esters. PNG media_image1.png 148 606 media_image1.png Greyscale A triacylglyceride (or triglyceride) is an ester, not an acid. PNG media_image4.png 470 326 media_image4.png Greyscale Paragraph [0015] of the Specification refers to “TAG content” and not “fatty acid content”. PNG media_image5.png 244 634 media_image5.png Greyscale Paragraph [0015] may provide support for TAG content but not fatty acid content. The phrase “about 50% or more of the fatty acid content is esterfied in monoacylglyceride form” in claim 34, lines 10-11 is new matter. Fatty acids, like oleic acid, are NOT esters. PNG media_image1.png 148 606 media_image1.png Greyscale A monoacylglyceride (or monoglyceride) is an ester, not an acid.

PNG media_image5.png 244 634 media_image5.png Greyscale Paragraph [0015] may provide support for TAG content but not fatty acid content. Claim Rejections - 35 USC § 112 Claims 1, 6, 31 and 34, 36 and 38 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 “30%” in claim 1, line 10 is vague and indefinite as it is unclear whether the % is by weight, volume, mole or something else. The phrase “30%” in claim 1, line 10 is vague and indefinite as it is unclear whether the % includes the terminal “H” in the acid (like with oleic acid) or is the terminal “H” not included like with MAGS.

The phrase “5%” in claim 1, line 13 is vague and indefinite as it is unclear whether the % is by weight, volume, mole or something else. The phrase “5%” in claim 1, line 13 is vague and indefinite as it is unclear whether the % includes the terminal “H” in the acid (like with oleic acid) or is the terminal “H” not included like with TAGS. PNG media_image1.png 148 606 media_image1.png Greyscale PNG media_image4.png 470 326 media_image4.png Greyscale The phrase “tocopherols naturally present in the processed oil” in Claim 1, lines 19-20 is vague and indefinite it is unclear how tocopherols can be naturally present in “processed oil” as the processed oil is not canola seeds. Canola seeds naturally contain tocopherols, however, processed oil is a product made by humans and not natural. PNG media_image8.png 224 236 media_image8.png Greyscale The phrase “tocopherols naturally present in the processed oil” in Claim 1, lines 19-20 is vague and indefinite it is unclear how one can determine whether the tocopherols are naturally present or added as the tocopherols are identical no matter the source. The phrase “1% to about 2%” in claim 34, lines 8-9 is vague and indefinite as it is unclear whether the % is by weight, volume, mole or something else. The phrase “50%” in claim 34, line 10 is vague and indefinite as it is unclear whether the % is by weight, volume, mole or something else. The phrase “50%” in claim 34, line 10 is vague and indefinite as it is unclear whether the % includes the terminal “H” in the acid (like with oleic acid) or is the terminal “H” not included like with MAGS.

ANSWERS TO APPLICANT’S ARGUMENTS The limitations of the amended/new claims are discussed above. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
