Office Action

§112
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 . 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. Information Disclosure Statement The information disclosure statement (IDS) submitted on 07/07/2025 has been considered by the examiner. Oath/Declaration Oath/Declaration as file 07/12/2024 is noted by the Examiner. Claim Objections Claims 2-10 and 14-16 are objected to because of the following informalities: Dependent Claims 2-10 disclose the preamble “The contacting member as claimed in claim…” while Independent Claim 1 discloses the preamble “A contacting member of a contact probe for a probe system for performing a functionality test to a device under test…”. In order to maintain consistency, please change the preamble of Dependent Claims 2-10 so that they match the preamble of Independent Claim 1. Dependent Claims 14-16 disclose the preamble “The method as claimed in claim…” while Independent Claim 13 discloses the preamble “A method of manufacturing a contacting member for a contact probe for performing a functionality test to a device under test…”. In order to maintain consistency, please change the preamble of Dependent Claims 14-16 so that they match the preamble of Independent Claim 13. Appropriate correction is required.

The following is an examiner’s statement of reasons for allowance: Regarding claim 1, the prior art does not teach or suggest, in combination with the rest of the limitations of claims 1, “…wherein the contacting member comprises a top side and a bottom side; when the contacting member performs the functionality test to the device under test, the bottom side of the contacting member faces toward the device under test; the bottom side of the contacting member comprises a lower surface located at the body, a tip bottom surface located at the contact tip, and a tip transition surface located at the tip transition section; the contact end is located on a front side of the tip bottom surface; a rear side of the tip bottom surface and the lower surface have a height difference therebetween; the tip transition surface extends from the lower surface to the rear side of the tip bottom surface in a way of gradually changing in height.” Claims 2-12 and 17-20 are also allowed as they further limit allowed claim 1. Regarding claim 13, the prior art does not teach or suggest, in combination with the rest of the limitations of claims 13, “…and at least one transition surface located at the at least one transition region, the second surface being higher than the first surface, the transition surface extending upwardly from the first surface to the second surface in a way of gradually changing in height; and defining a plurality of said contacting members by removing partial material of the substrate, the step of defining the contacting members comprising defining a contact tip of each of the contacting members in the relatively thicker region of the substrate, defining a body of each of the contacting members in the relatively thinner region of the substrate, and performing a cutting process to the substrate in correspondence with a contour of the contacting members.” Claims 14-16 are also allowed as they further limit allowed claim 13. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Hayden et al. US 2008/0042673 - A direct current and a modulation signal are simultaneously applied to contact pads on a device under test, such as a laser diode, with a probe that reduces signal distortion and power dissipation by transmitting a modulated signal through an impedance matching resistor and transmitting of a direct current over a second signal path that avoids the impedance matching resistor. Crippa et al. US 2017/0122980 - A contact probe for a testing head of an apparatus for testing electronic devices is described comprising a body extending between a contact tip and a contact head, that contact probe comprising at least one first section and one second section made of at least two different materials and joined together in correspondence of a soldering line. Crippa et al. US 2024/0044940 - A contact probe is disclosed having a first contact end portion adapted to abut onto a contact pad of a device under test, a second contact end portion adapted to abut onto a contact pad of a PCB board of a testing apparatus, and a rod-shaped probe body extended between the first and second contact end portions according to a longitudinal direction.
