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.
Claim 1 is rejected under 35 U.S.C. 103 as being unpatentable over Ma et al., and further in view of Alexander et al. DE 10023554 A1 . DE 10023554 A1 is a published patent hereinafter to be referred to as the Alexander patent.
Regarding claim 1, Ma discloses a method for determining conformity of a rolling roll, the method being a method for determining conformity, in a rolling mill including one or two or more stands, of a rolling roll to be evaluated, the method comprising a rolling load data acquisition step of acquiring rolling load operation data of the stand having the roll to be evaluated; a circumferential speed data acquisition step of acquiring circumferential speed operation data of the roll to be evaluated; and a vibration analysis step of analyzing a vibration behavior of the stand using the rolling load operation data of the stand having the roll to be evaluated acquired in the rolling load data acquisition step (Ma Para [0001]: a method using a neural network prediction for high speed cold rolling mill frame vibration conditions in the rolling process; Para [0007]: data collection and processing: mill the vibration data of the same time period in the predicted production process, rolling force, rolling speed). Ma fails to disclose a rolling mill having a plurality of rolling rolls; a surface shape estimation step of estimating a surface shape of the roll to be evaluated during rolling of a metal strip, the surface shape of the roll to be evaluated comprising amplitude information associated with a pitch of polygonal irregularities formed on a surface of the roll to be evaluated, the surface shape of the roll to be evaluated being estimated using an analysis result of the vibration behavior of the stand having the roll to be evaluated by the vibration analysis step and the circumferential speed operation data of the roll to be evaluated acquired in the circumferential speed data acquisition step; and a conformity determination step of determining the conformity of the roll to be evaluated based on the surface shape of the roll to be evaluated estimated by the surface shape estimation step.
Alexander teaches a method for monitoring a rolling mill plant, in particular for detecting damage on its roll surfaces. The rolling mill including a plurality of rolling rolls (30,34,36,42; FIG.1), and a surface shape estimation step of estimating a surface shape of the roll to be evaluated during rolling of a metal strip (Alexander Para [0001] and [0003]), the surface shape of the roll to be evaluated comprising amplitude information associated with a pitch of irregularities formed on a surface of the roll to be evaluated, the surface shape of the roll to be evaluated being estimated using an analysis result of the vibration behavior of the stand having the roll to be evaluated by the vibration analysis step and the circumferential speed operation data of the roll to be evaluated acquired in the circumferential speed data acquisition step (Alexander Para [0019]: Measurement parameters, in particular accelerations, velocities or distances, are recorded using a suitable sensor. A particularly suitable sensor is a vibration sensor that can record acceleration, velocity and/or displacement signals.); and a conformity determination step of determining the conformity of the roll to be evaluated based on the surface shape of the roll to be evaluated estimated by the surface shape estimation step (Alexander Para [0023]: Such a characteristic value can, for example, consist of a specific combination of weighted amplitudes at certain frequencies that is identifying for a specific type of damage or that recognizes a usage condition of the roller within permissible parameters.).
Alexander does not teach polygonal irregularities formed on a surface of a roll to be evaluated; however, Alexander does teach a defect or damage to the surface of the roll to include a flattening of the roller or a localized area on the roller (Alexander Para [0006]) or a local increase in height on a roller (Alexander Para [0007]). It is known within the art that polygonal wear refers to uneven wear along a circumference of rotating components, such as rolling mill work rolls, forming a polygon-like profile rather than a smooth circle.
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the method for determining conformity of a rolling roll disclosed in Ma, to include a surface shape estimation step of estimating a surface shape of a roll during rolling of a metal strip, the surface shape of the roll to be evaluated comprising amplitude information, and a conformity determination step of determining the conformity of the roll to be evaluated, as taught by Alexander, given the cruciality of the rollers surface in producing a metal strip (See Alexander Para [0005]: In such a production process, the rollers and especially their surfaces are therefore crucial for the quality of the produced strips.).

Regarding claim 2, Ma in view of Alexander discloses the method for determining conformity of a roll, comprising a rolling load acquisition step, a circumferential speed data acquisition step, a vibration analysis step, a surface shape estimation step, and a conformity determination step (See claim 1 rejection above). However, Ma in view of Alexander fails to disclose an initial surface shape acquisition step of acquiring an initial surface shape of the roll to be evaluated before the roll to be evaluated is incorporated into any of the stands having the roll to be evaluated, wherein the surface shape estimation step estimates the surface shape of the roll to be evaluated using the initial surface shape of the roll to be evaluated acquired in the initial surface shape acquisition step.
Saito teaches an initial surface shape acquisition step of acquiring an initial surface shape of the roll to be evaluated before the roll to be evaluated is incorporated into any of the stands having the roll to be evaluated, wherein the surface shape estimation step estimates the surface shape of the roll to be evaluated using the initial surface shape of the roll to be evaluated acquired in the initial surface shape acquisition step (Saito Description Page 6, 3rd Paragraph: the present invention predicts the profile of a rolling roll by using a prediction model, and calculates the predicted roll profile; In the rolling method, the profile of the rolling roll is actually measured during the passing of the rolled material, and the profile deviation between the measured roll profile and the initial profile or the profile deviation between the predicted roll profile).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the method for determining conformity of a rolling roll disclosed by Ma in view of Alexander, to include an initial surface shape acquisition step of acquiring an initial surface shape of the roll to be evaluated, as taught by Saito, to predict the outcome result of the rolled metal strip (See Saito Para [0017]: the present invention also predicts the profile of a roll by using a predictive model, and uses the predicted roll profile and the deformation of the rolling mill and the rolled material to predict the rolled sheet.).
Regarding claim 7, Ma in view of Alexander and Saito discloses the method for determining conformity of a rolling roll, comprising an initial surface shape acquisition step, a rolling load acquisition step, a circumferential speed data acquisition step, a vibration analysis step, , a surface shape estimation step, wherein the initial surface shape of the roll to be evaluated acquired in the initial surface shape acquisition step is used to estimate the surface shape of the roll to be evaluated during the rolling of the metal strip, and a conformity determination step (See claim 2 rejection above), wherein the surface shape of the roll to be evaluated is amplitude information associated with a pitch of irregularities formed on a surface of the roll to be evaluated (Alexander Para [0023]: Such a characteristic value can, for example, consist of a specific combination of weighted amplitudes at certain frequencies that is identifying for a specific type of damage or that recognizes a usage condition of the roller within permissible parameters.).
