Claim 13 O’Donnell discloses the array of claim 1, further comprises a support substrate having thermal conduction pathways configured to provide thermal conduction between the array and an object (paragraph [0205], conductive paths). Claim 14 O’Donnell discloses an array, comprising: a support substrate having thermal conduction pathways configured to provide thermal conduction between the array and an object (system 260); a plurality of enclosures (enclosures 262); a plurality of phase change materials each disposed in a corresponding enclosure of the plurality of enclosures (paragraph [0199]), wherein each of the plurality of enclosures includes a phase change material having a phase transition temperature that is different than remaining phase transition temperatures of remaining phase change materials of the plurality of phase change materials (paragraph [0198-0199]); a plurality of magnetic particles disposed in the plurality of enclosures (paragraph [0198], particles 14 are magnetic); and a sensor substrate having a plurality of sensors electrically coupled with the sensor substrate (system 260), where each of the plurality of sensors is configured to measure a corresponding set of magnetic particles in a corresponding enclosure (paragraphs [0197-0199]) and detect: a first magnetic response associated with the corresponding set of magnetic particles in a first location within the corresponding enclosure (paragraph [0198], first sensitivity), and a second magnetic response associated with the corresponding set of magnetic particles in a second location within the corresponding enclosure (paragraph [0198], second sensitivity), wherein the first location and the second location are different (Fig. 26, different compartments). Claim 15 O’Donnell discloses the array of claim 14, further comprises a magnet configured to attract or repel the plurality of magnetic particles (paragraph [0205], magnetic structure used). Claim 16 O’Donnell discloses the array of claim 14, further comprises one or more of heating elements or cooling elements (paragraph [0140], heating element included). Claim 17 O’Donnell discloses the array of claim 14, further comprises a passivation layer covering the plurality of enclosures (paragraph [0140], passivation included). Claim 18 O’Donnell discloses the array of claim 14, w herein the plurality of sensors are disposed at the bottom of the plurality of enclosures (paragraph [0099], top or bottom film forming). Claim 19 O’Donnell discloses the array of claim 1, wherein each of the plurality of sensors include a giant magnetoresistance (GMR) element (paragraph [0174]). Claim 20 O’Donnell discloses a temperature tracking system, comprising: a plurality of arrays removably attached to a plurality of objects (paragraph [0003]), each array of the plurality of arrays includes: a support substrate having thermal conduction pathways configured to provide thermal conduction between the array and a corresponding object of the plurality of objects (system 260); a plurality of enclosures (enclosures 262); a plurality of phase change materials each disposed in a corresponding enclosure of the plurality of enclosures (paragraph [0199]), wherein each of the plurality of enclosures includes a phase change material having a phase transition temperature that is different than remaining phase transition temperatures of remaining phase change materials of the plurality of phase change materials (paragraph [0198-0199]); a plurality of magnetic particles disposed in the plurality of enclosures (paragraph [0198], particles 14 are magnetic); and a sensor substrate having a plurality of sensors electrically coupled with the sensor substrate (system 260), where each of the plurality of sensors is configured to measure a corresponding set of magnetic particles in a corresponding enclosure (paragraphs [0197-0199]) and detect: a first magnetic response associated with the corresponding set of magnetic particles in a first location within the corresponding enclosure (paragraph [0198], first sensitivity), and a second magnetic response associated with the corresponding set of magnetic particles in a second location within the corresponding enclosure (paragraph [0198], second sensitivity), wherein the first location and the second location are different (Fig. 26, different compartments); a magnet configured to attract or repel the plurality of magnetic particles (paragraph [0205], magnetic structure used); and a controller configured to determine a temperature or a temperature range reached by each of the plurality of objects based on measurements by each corresponding plurality of sensors (paragraph [0234]). 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 12 is rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Pub. 2023/0349987 (“O’Donnell”) in view of U.S. Patent Pub. 2015/0133827 (“Seo”). Claim 12 O’Donnell discloses the array of claim 1. O’Donnell does not appear to explicitly disclose further comprises adhesive pads configured to removably attach the array to an object. Seo discloses incorporated removably attached adhesive pads (paragraph [0036]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have incorporated further comprises adhesive pads configured to removably attach the array to an object as disclosed by Seo, into the device of O’Donnell, for the purpose of providing secure contact between measurement and apparatus (Seo, paragraph [0036]).
