Office Action

§103
FINAL REJECTION 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 . Response to Arguments Applicant’s arguments with respect to claim(s) 1-7, 9, 10-16, 21, and 22 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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. Claim(s) 1-3, 21, and 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Beardslee et al. U.S. Patent Application Publication 2023/0003689 in view of Rivas et al. U.S. Patent Application Publication 2017/0134002 and further in view of Qasaimeh et al. U.S. Patent Application Publication 2022/0146549. With respect to claims 1-3, 21, and 22, Beardslee teaches a sensor comprising a resonator structure (MEMS resonator having an semicircular annulus 110 and cantilever stem 120, paragraph 61, figure 1); and a polymeric 3D printed coating disposed on a surface of at least a portion of the sensor (The resonator is coated with sensing polymer, paragraphs 62, 65, 66, 70. Beardslee further teaches wherein the resonator structure comprises a semicircular annulus and a cantilever (MEMS resonator having an semicircular annulus 110 and cantilever stem 120, paragraph 61, figure 1), wherein the polymeric printed coating is disposed on at least a portion of an top or outer surface of the semicircular annulus (figure 1), and exposing the sensing system to an environment containing one or more analytes (paragraphs 66); and measuring a frequency change of the sensor in response to absorption of the one or more analytes by the polymeric 3D printed coating (paragraph 67, figure 4). Beardslee fails to teach forming a polymer 3D printed structure by two-photon polymerization on the cantilever-based resonator head region and wherein the polymeric 3D printed coating comprises a three-dimensional scaffold structure. Rivas teaches methods for biological and chemical sensing, and methods for forming MEMS resonator devices and fluidic devices (abstract) having an active region 30 of the resonator device 10, a top side electrode 58 embodying a patterned enhanced surface area (interpreted as three dimensional scaffold structure) element with multiple upwardly extending protrusions 60 separated by grooves or recesses 62, with the upwardly extending protrusions 60 and grooves or recesses 62 arranged over an active area 30 (paragraph 87, figure 5A). Qasaimeh teaches a 3D microscopy probe system where the 3D probes are manufactured using commercial two-photon polymerization (TPP) 3D printer (paragraphs 56-59). Accordingly, it would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the sensing film of Beardslee with the a patterned enhanced surface area that is a three dimensional structure as taught by Rivas in order to improved sensor performance by enabling capture of an increased amount of analyte (paragraph 89, Rivas) and further modify the polymer sensing film forming of Beardslee with the method of forming a 3D sensing polymer as taught by Qasaimeh in order to produce innovative 3D probe tip materials, geometries, integrated elements, and designs that cannot be obtained by the traditionally used Si probe microfabrication techniques (paragraph 59). Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Beardslee et al. U.S. Patent Application Publication 2023/0003689 in view of Rivas et al.
