Office Action

§102
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 . Response to Amendment This office action is responsive to the amendment filed 22 December 2025. As directed by the amendment: claims 1-15 remain cancelled and claims 16-35 are pending. Response to Arguments Applicant's arguments filed 22 December 2025 have been fully considered but they are not persuasive. Applicant argues on pages 7-9, that the part 118 in Kühn is not a dose dispensing part, however, as previously pointed out in the Non-Final Rejection on 26 September 2025, the part 118 is part of the dose dispensing mechanism of the device as it is integral to the device actually dispensing the amount of medication that is required. The device mechanism includes the parts 116 and 118 for proper function and the dispensing process is listed in multiple paragraphs of Kühn and specifically cited in the action in paragraphs 0023 and 0024. The dispensing and setting mechanism of the device are both connected and the device 100 of Kühn is an injection device which uses multiple parts to perform said injection. Additionally, applicant argues that “the part” of the dose dispensing mechanism needs to be aligned with a window. As previously stated, 118 is the “the part” and 116 is aligned with 118. Claim Rejections - 35 USC § 102 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) 16-35 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kühn (EP 3016699).

Regarding claim 17, Kühn discloses wherein the optical sensor arrangement comprises a sensor array configured to capture an image of the part (¶[0029], where the second sensor 200 is one of multiple sensors configured to gather data on the device). Regarding claim 18, Kühn discloses wherein the sensor array is a one-dimensional array (Fig. 4, where the primary and secondary sensors are arranged in a one-dimensional format) Regarding claim 19, Kühn discloses wherein the accessory is configured to cause the sensor array to capture a first image of the part that moves in response to movement of the dose setting mechanism after it has been detected that an injection has been completed (¶[0034]-[0035]) Regarding claim 20, Kühn discloses wherein the accessory is further configured to cause the sensor array to capture a second image of the part that moves in response to movement of the dose setting mechanism prior to an injection having started (¶[0027]-[0029] & [0033]-[0035]). Regarding claim 21, Kühn discloses wherein the accessory is configured to use both the first and second images to calculate a displacement of the part (¶[0034]-[0035], where the information gathered between the two images determines the amount of insulin delivered between the first and second images by reading characters on the mechanism). Regarding claim 22, Kühn discloses wherein the accessory is configured to calculate the displacement of the part by detecting locations of edges in the first and second images and by comparing the positions of the edges between the first and second images (¶[0034]-[0035], where the OCR sensor reads characters or images and compares the difference between them to determine the dose dialed). Regarding claim 23, Kühn discloses wherein the accessory comprises a communication module and is configured to use the communication module to communicate images acquired by the optical sensor arrangement to an external device for processing (¶[0031] & [0046]). Regarding claim 24, Kühn discloses wherein the communications module is a wireless communications module (¶[0046]). Regarding claim 25, wherein the part is a last dose nut threaded to a drive member of the dose setting mechanism, the last dose nut being arranged to advance along the drive member through a threaded engagement and in response to operation of the dose setting mechanism (¶[0039]-[0041]). Regarding claim 26, Kühn discloses wherein the injection device includes a receiving portion for receiving the attachment portion, and wherein the receiving portion is not covered by a cap of the injection device when the cap is operatively installed (Fig. 1 & Fig. 3, where the cap 212 only covers the discharging end of the device and module 200 is attached to 214 at a proximal end of the device away from the cap). Regarding claim 27, Kühn discloses an accessory (Fig. 2, 200) for an injection device, the accessory comprising: an attachment portion configured to attach the accessory to the injection device comprising a dose setting mechanism for dialing a dose and a dose dispensing mechanism configured to inject the dose and including a part that is configured to move in response to the movement of the dose setting mechanism (¶[0023]-[0024],[0027], where 118 is a part that moves in response to a dose setting mechanism and the dose dispensing process includes the parts 116 and 118 for the device to properly dispense the required dose when the device is ready to be used and button 120 is pressed); and a body that houses an optical sensor arrangement (¶[0029] & [0034]), wherein the attachment portion is configured to align the optical sensor arrangement to a window in the injection device, the window being aligned with the part to determine a dose dialed by the dose setting mechanism (¶[0034], 116, 118, where the window shows the dosage and the optical sensor detects movement internally).
