Office Action

§103
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 . Election/Restrictions Claims 5-6 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 12/17/2025. Claim Rejections - 35 USC § 103 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 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. Claims 1-4 are rejected under 35 U.S.C. 103 as being unpatentable over Tseunetomo (US 20190248698). Regarding claims 1-2, Tseunetomo discloses a method for manufacturing a glass sheet having a first main surface, a second main surface, and a through hole penetrating between the first main surface and the second main surface ¶[0231], the method comprising: a modifying step of modifying a preset formation part by irradiation of laser light yielding modified portions ¶ [0233], Tseunetomo discloses an etching step of etching the glass sheet by immersing the glass sheet in an etchant ¶ [0255]-[0258], ¶ [0261] ultrasonic waves of stirring wet etching removes the modified portions and forms through holes, or blind holes. Tseunetomo does not specifically break up the overall disclosure of the etching into “a first etching step of etching the glass sheet in which the preset formation part does not penetrate; and a second etching step of etching the glass sheet in which the preset formation part penetrates, after the first etching step” however Tseunetomo discloses the etching is performed to turn the modified portions into through holes and etching time and temperature are controlled as well as stirring to control the etching rate ¶ [0258] and [0261] respectively. KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007) Supreme court stated when a work is available in one field of endeavor, design incentives and other market forces can prompt variations of it. Tseunetomo discloses how the etching rate can be increased by raising the temperature, stronger etchant, or stirring the etchant relative to the glass. It is obvious to one of ordinary skill in the art to increase the etching rate throughout the etching process to make the etching process efficient while achieving the desired diameter through hole. Increasing the etching rate once the hole penetrates is mere optimization of the etching parameters disclosed by Tseunetomo absent any unexpected results. Regarding claims 3-4, Tseunetomo discloses the etching is performed to turn the modified portions into through holes and etching time and temperature are controlled as well as stirring to control the etching rate ¶ [0258] and [0261] respectively. KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007) Supreme court stated when a work is available in one field of endeavor, design incentives and other market forces of efficiency can prompt variations of it. Tseunetomo discloses how the etching rate can be increased by stirring the etchant relative to the glass. It is obvious to one of ordinary skill in the art to increase the etching rate throughout the etching process to make the etching process efficient while achieving the desired diameter through hole. Increasing the etching rate once the hole penetrates appears to be mere optimization of the etching parameters discussed by Tseunetomo absent any unexpected results. In reference to claim 4, MPEP 2144.04 states In re Gazda, 219 F.2d 449, 104 USPQ 400 (CCPA 1955) mere reversal of movement is obvious to a skilled artisan, Therefore it would be obvious to one of ordinary skill in the art to stir the etchant releative to the glass by moving the etchant or moving the glass immersed in the etchant. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Komochi (JP 2011037707) as cited in the machine translation provided herein discloses a method comprising a modifying step of modifying a preset formation part by irradiation of laser light yielding an altered part (See step i described on at least Pages 2 and 7 ¶8) and an etching step of etching the glass sheet by immersing the glass sheet in an etchant (Step ii and at least Pages 2 and 7 ¶8) JP 2008194915 increase etch rate formation of through hole Any inquiry concerning this communication or earlier communications from the examiner should be directed to JODI COHEN FRANKLIN whose telephone number is (571)270-3966.
