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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 32 and 33 are rejected under 35 U.S.C. 103 as being unpatentable over Keller in view of Krulevitch at al. (US Pub No. 20120004637 A1, herein, Krulevitch). Regarding claim 32, Keller discloses the injection device as set forth above, however, Keller does not expressly disclose wherein fastener comprises a body with a transparent window. Krulevitch teaches a fastener (202 – Fig.3) comprising a body with a transparent window (218 – Fig.3). It would be obvious to one in the ordinary skill in the art, before the effective filing date of the applicant’s claimed invention to modify the fastener of Keller to comprise a body with a transparent window as taught by Krulevitch since Krulevitch teaches that the window allows the user to view the dosage amount, allowing the user to verify the intended dose before administration (Krulevitch, Para [0063]). Regarding claim 33, Keller discloses the injection device as set forth above, however, Keller does not expressly disclose wherein the drive mechanism comprises a number sleeve at least partially arranged inside the housing and wherein a portion of the number sleeve is visible through the transparent window of the fastener. Krulevitch teaches a drive mechanism (216 – Fig.2) comprising a number sleeve (220 – Fig.1) at least partially arranged inside a housing and wherein a portion of the number sleeve is visible through the transparent window of the fastener (“The dosage display can output the amount of fluid dispensed on a display screen such as a printed display” - Para [0032]). It would be obvious to one in the ordinary skill in the art, before the effective filing date of the applicant’s claimed invention to modify the drive mechanism of Keller to comprise a number sleeve that is visible through the transparent window of the fastener as taught by Krulevitch since Krulevitch teaches that window and number sleeve allows the user to view the dosage amount, allowing the user to verify the intended dose before administration (Krulevitch, Para [0063]). Claims 36 and 37 are rejected under 35 U.S.C. 103 as being unpatentable over Keller in view of Cirillo et al. (US Patent No. 10773032 B2). Regarding claim 36, Keller discloses the supplementary device as set forth above, however, Keller does not expressly disclose wherein the supplementary device comprises a secondary fastener configured to clasp at least partially around an outside surface of the housing of the injection device. Cirillo teaches a supplementary device (1 – Fig.1) comprises a secondary fastener (15 – Fig.5) configured to clasp at least partially around an outside surface of a housing (Shown at 2 – Fig.5) of an injection device (2 – Fig.5, Fig.5). It would be obvious to one in the ordinary skill in the art, before the effective filing date of the applicant’s claimed invention to modify the supplementary device of Keller to comprise a secondary fastener as taught by Cirillo so that the monitoring device of the invention is automatically correctly located and positioned on the injection pen (Cirillo, Col.6, lines 17-18). Regarding claim 37, Keller discloses the supplementary device as set forth above, however, Keller does not expressly disclose the device further comprising: a logic circuit; a signal generator connected to the logic circuit; and at least one of a switch and a detector connected to the logic circuit and operable to detect a correct assembly of the supplementary device to the housing of the injection device wherein the logic circuit is operable to generate at least one of an audible, visual or tactile signal via the signal generator in response to a detection of a correct assembly of the supplementary device to the housing of the injection device. Cirillo teaches a logic circuit (41 - Fig.14); a signal generator (13 – Fig.22) connected to the logic circuit; and at least one of a switch (40 – Fig.22) and a detector (44 – Fig.22) connected to the logic circuit and operable to detect a correct assembly of the supplementary device to the housing of the injection device (“signify to the user that the monitoring device is correctly mounted and positioned on the injection pen” – Col.7, lines 33-35) wherein the logic circuit is operable to generate at least one of an audible, visual or tactile signal via the signal generator in response to a detection of a correct assembly of the supplementary device to the housing of the injection device (“ensure that the monitoring device is correctly mounted on the injection pen “ – Col.9, lines 22-33, “are in communication with the processor which is in turn communicable with an external device interface” – Col.9, lines 31-32). It would be obvious to one in the ordinary skill in the art, before the effective filing date of the applicant’s claimed invention to modify the supplementary device of Keller to comprise a logic circuit, a signal generator, at least one switch, a detector, and wherein the logic circuit generates a signal in response to a detection of a correct assembly of the supplementary device as taught by Cirillo since these features provide confirmation of proper attachment, reduce user assembly errors, and ensure the device is in an operational state before use.
