Office Action

§102
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 . Introduction Claims 1-20 are currently pending in this application and are subject to examination herein. Information Disclosure Statement The information disclosure statement (IDS) submitted on 10/12/2025 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-5 and 11-15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Pat. Pub. No. 2018/0368317 to Shultze Selting et al. (hereinafter Schultze) (cited by Applicant in IDS filed on 10/12/2025). Regarding claim 1, Schultze discloses a method for adjusting a header (harvesting head 2) (Abstract; Figs. 1-3; Paras. [0030], [0031], [0034]-[0040]) mounted on an agricultural harvester (Para. [0001]), wherein the header (harvesting head 2) (Abstract; Figs. 1-3; Paras. [0030], [0031], [0034]-[0040]) includes a central section (middle section 4) (Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) and at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]), wherein the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) extends between an inner portion (e.g., portion closest from middle section 4) (see Figs. 1-4) and an outer portion (e.g., portion farthest from middle section 4) (see Figs. 1-4), wherein the inner portion (e.g., portion closest from middle section 4) (see Figs. 1-4) of the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) is pivotally coupled (Figs. 3-4; Claim 1) to the central section (middle section 4) (Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]), wherein a ground engaging device (sensor(s) 10) (Abstract; Figs. 1, 3, 4; Paras. [0031], [0034]-[0036], [0039], [0040]) is mounted on the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) adjacent (see Figs. 1, 4) the outer portion (e.g., portion farthest from middle section 4) (see Figs. 1-4), wherein the ground engaging device (sensor(s) 10) (Abstract; Figs. 1, 3, 4; Paras. [0031], [0034]-[0036], [0039], [0040]) has an adjustable height (see Para. [0031]), the method comprising the steps of: determining a flex position (e.g., position based on bending angle) (Paras. [0016], [0017], [0039], [0040]) of the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) relative to the central section (middle section 4) (Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) ; determining whether the flex position (e.g., position based on bending angle) (Paras. [0016], [0017], [0039], [0040]) of the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) exceeds a first threshold (e.g., whether “limit value” is exceeded) (Paras. [0016], [0017], [0039], [0040]; Claim 1); and if it is determined that the flex position (e.g., position based on bending angle) (Paras. [0016], [0017], [0039], [0040]) of the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) exceeds the first threshold (e.g., whether “limit value” is exceeded) (Paras. [0016], [0017], [0039], [0040]; Claim 1), decreasing the flex position (e.g., position based on bending angle) (Paras. [0016], [0017], [0039], [0040]). Regarding claim 2, Schultze discloses the method of claim 1 (see above). Furthermore, Schultze discloses a method further comprising the steps of: determining a measured height (ground distance 30) (Figs. 3, 4; Paras. [0001], [0006], [0021], [0039], [0040]; Claim 1) of the central section (middle section 4) (Abstract; Figs. 1-4; Paras.

[0030], [0031], [0034]-[0040]); and if it is determined that the flex position (e.g., position based on bending angle) (Paras. [0016], [0017], [0039], [0040]) of the at least one side wing section (side section(s) 6; Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) does not exceed the first threshold (e.g., whether “limit value” is exceeded) (Paras. [0016], [0017], [0039], [0040]; Claim 1), sending the measured height (ground distance 30) (Figs. 3, 4; Paras. [0001], [0006], [0021], [0039], [0040]; Claim 1) of the central section (middle section 4) (Abstract; Figs. 1-4; Paras. [0030], [0032], [0033], [0038]-[0040]) as a central Automatic Header Height Control (AHHC) signal (adjusting signal) (Abstract; Paras. [0001], [0009], [0010], [0018], [0020], [0039]) to the agricultural harvester (Para. [0001]). Regarding claim 3, Schultze discloses the method of claim 2 (see above). Furthermore, Schultze discloses a method wherein the step of decreasing the flex position (e.g., position based on bending angle) (Paras. [0016], [0017], [0039], [0040]) comprises adjusting (Para. [0020]) the central AHHC signal (Para. [0020]) before sending the adjusted central AHHC signal (adjusting signal) (Abstract; Paras. [0001], [0009], [0010], [0018], [0020], [0039]) to the agricultural harvester (adjusting signal) (Abstract; Paras. [0001], [0009], [0010], [0018], [0020], [0039]). Regarding claim 4, Schultze discloses the method of claim 3 (see above). Furthermore, Schultze discloses a method wherein the adjusted central AHHC signal (adjusting signal) (Abstract; Paras. [0001], [0009], [0010], [0018], [0020], [0039]) is based on the flex position (e.g., position based on bending angle) (Paras.
