Office Action

§102 §103
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 . Information Disclosure Statement The references cited on a Form PTO 1449 have been considered. Specification The specification has been checked to the extent necessary to determine the presence of all possible minor errors. However, the applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. 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. Claim(s) 1, 6-7, 9-12, 17-18 and 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Iwasaki (U.S. 2023/0014175 A1). Iwasaki discloses the following claimed limitations: Regarding independent Claim 1, a printer (Title) comprising: at least one thermal printhead (TPH, Abstract) comprising: a plurality of dots, wherein each dot has an associated resistance, wherein the plurality of dots are arranged in a first pattern, and wherein the first pattern includes a first end and a second end; and a processor and a non-transitory memory (31, 32, 35, §§0026-0028 and Fig. 3) comprising a computer program code, the non-transitory memory and the computer program code configured to, with the processor, cause the printer to: determine a resistance value for each dot of the plurality of dots (Abstract); compare the resistance value associated with at least one dot associated with the first end and at least one dot associated with the second end with a predefined threshold resistance value (§§0057-0066 and Figs. 8-9); identify at least one dot having a high resistance value based at least on the comparison (§§0057-0066 and Figs. 8-9); and identify a type of TPH of the at least one TPH based at least on the at least one dot identified (freshly replaced or previously installed, §§0057-0066 and Figs. 8-9). Regarding Claim 6, wherein the predefined threshold resistance value associated with the plurality of dots is stored in the non-transitory memory (§0038). Regarding Claim 7, wherein the non-transitory memory and the computer program code are configured to, with the processor, cause the printer to read the resistance value of each of the plurality of dots during a booting phase of the printer (§0038-§0039). Regarding Claim 9, wherein the plurality of dots define a range between 0-N dots (§0039). Regarding Claim 10, wherein the type of TPH of the at least one TPH identified is one of a plurality of TPH series (freshly replaced or previously installed, Abstract). Regarding Claim 11, wherein the first pattern of the plurality of dots corresponds to a resistance pattern of the plurality of dots, wherein the resistance pattern defines the type of TPH of the at least one TPH (freshly replaced or previously installed, §§0057-0066 and Figs. 8-9). Regarding independent Claim 12, a method (Title) comprising: determining a resistance value for each dot of a plurality of dots of at least one thermal printhead (TPH, Abstract), wherein the plurality of dots are arranged in a first pattern, and wherein the first pattern includes a first end and a second end; comparing the resistance value associated with at least one dot associated with the first end and at least one dot associated with the second end with a predefined threshold resistance value (§§0057-0066 and Figs. 8-9); identifying at least one dot having a high resistance value based at least on the comparison (§§0057-0066 and Figs. 8-9); and identifying a type of TPH of the at least one TPH, based at least on the at least one dot identified (freshly replaced or previously installed, §§0057-0066 and Figs. 8-9). Regarding Claim 17, storing the predefined threshold resistance value associated with the plurality of dots (§0038). Regarding Claim 18, reading the resistance value of each of the plurality of dots during a booting phase of a printer (§0038-§0039). Regarding Claim 20, 20. The method of claim 12, wherein the type of TPH of the at least one TPH identified one of a plurality of TPH series (freshly replaced or previously installed, §§0057-0066 and Figs. 8-9). 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) 8 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Iwasaki (U.S. 2023/0014175 A1). Iwasaki discloses the following claimed limitations: Regarding Claim 8, all limitations of Claim 1, from which this Claim depends; wherein the resistance value of each dot defines a range of TPH resistance specification ohms +/- certain manufacturing tolerance (§0034). Regarding Claim 19, all limitations of Claim 12, from which this Claim depends; wherein the resistance value of each dot defines a range of TPH resistance specification ohms +/- certain manufacturing tolerance (§0034). Iwasaki does not disclose the following claimed limitations: Regarding Claim 8, the range of TPH resistance specification being 900 ohms +/- 7%. However, Iwasaki does disclose similar ranges (Figs. 8-9), making Claim 8 obvious over prior art. See MPEP 2144.05 I. Regarding Claim 19, the range of TPH resistance specification being 900 ohms +/- 7%. However, Iwasaki does disclose similar ranges (Figs. 8-9), making Claim 8 obvious over prior art. See MPEP 2144.05 I. Claim(s) 2-4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Iwasaki (U.S. 2023/0014175 A1) as applied to Claim 1, in view of Erhardt (U.S. 2007/0081842 A1). Iwasaki discloses the following claimed limitations: Regarding Claims 2-4, all limitations of Claim 1, from which these Claims depend; Regarding Claim 3, wherein the at least one TPH further comprising a plurality of heaters, wherein each of the plurality of heaters is associated with one dot of the plurality of dots (§0023). Iwasaki does not disclose the following claimed limitations: Regarding Claim 2, wherein the non-transitory memory and the computer program code are configured to, with the processor, cause the printer to determine a thermal management technique based at least on the type of TPH of the at least one TPH identified. Regarding Claim 4, wherein the non-transitory memory and the computer program code are configured to, with the processor, cause the printer to adjust a thermal output of the plurality of heaters based at least on the determined thermal management technique. Erhardt discloses the following claimed limitations: Regarding Claim 2, wherein the non-transitory memory and the computer program code are configured to, with the processor, cause the printer to determine a thermal management technique based at least on the type of TPH of the at least one TPH identified (§§0049-0051). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to apply the teachings of Erhardt to the printer of Iwasaki to enable printing on various substrates. Regarding Claim 4, wherein the non-transitory memory and the computer program code are configured to, with the processor, cause the printer to adjust a thermal output of the plurality of heaters based at least on the determined thermal management technique (§§0004, 0007-0008, 0049-0051, 0067). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to apply the teachings of Erhardt to the printer of Iwasaki to enable printing on various substrates.
