DETAILED OFFICE 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 .
Drawings
The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the “cam” and cam “follower” in claim 16 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Figure(s) 12-14C, 15A should be designated by a legend such as --Prior Art-- because only that which is old is illustrated, as seen in Figure(s) 1-3C and 4 in Zheng et al. (WO 2019156852 A2). See MPEP § 608.02(g). Corrected drawings in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c)) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Objections
Claim(s) 1 is/are objected to because of the following informalities:
In claim 6, line 1, “the fluid delivery operation” should be corrected to “the fluid movement operation” to match language used in the previous claim(s).
In claim 9, line 3, “the portion within a fluid movement operation” should be changed to “the portion of a fluid movement operation” to match the language used in the previous claim(s).
In claim 15, line 4, “the for controlling fluid volume in the chamber” should be corrected to “the controlling fluid volume in the chamber”.
In claim 15, line 8, “a portion of a fluid movement operation” should be corrected to “the portion of the fluid movement operation” because this term was introduced in previous claims.
In claim 16, line 3, “a fluid movement operation” and “a cam” should be corrected to “the fluid movement operation” and “the cam” because these terms were previously introduced.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim 11 is/are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112
(preAIA ), second paragraph, as being indefinite for failing to particularly point out and
distinctly claim the subject matter which the inventor or a joint inventor (or for
applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 11 introduces the term “the pusher” in line 3. Claim 11 is dependent on claim 9, however claim 9 does not recite a “pusher” and therefore there is insufficient antecedent basis for this limitation in the claim. Applicant is therefore suggested to amend claim 11 to overcome rejection.
Claim Rejections - 35 USC § 102
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 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 –

Regarding claim 10, Zheng as modified disclosed all limitations of claim 9. Zheng also discloses wherein the pump is a syringe-type pump (reciprocating plunger-type pump [0048]) having a barrel as the chamber (chamber 38 in Fig. 3A) and the interface comprises a plunger (pump plunger 30 in Fig. 3A), the drive mechanism being operable to selectively drive the plunger to dispense fluid from the barrel (as the piston 30 is rotated by the DC motor and gearbox assembly, the piston 30 translates through the sleeve 24, guided by travel of the pin 28 on the piston through a helical slot 26 in the sleeve 24. Once the piston 30 translates fully through the sleeve 24 and completes its aspiration stage or dispensing stage of fluid [0058]), and the processing device is configured to generate the unloaded measured data during a dispensing fluid movement operation by temporarily retracting the plunger in the barrel a nominal amount (processing device configured to analyze pump measurements comprising the pump measurement for each of a plurality of the at least one of the aspirate stroke and the dispense stroke [0007]).
Regarding claim 13, Zheng disclosed all limitations of claim 9. Zheng further disclosed wherein the pump is a syringe-type pump (reciprocating plunger-type pump [0048]) having a barrel as the chamber (chamber 38 in Fig. 3A) and a plunger (pump plunger 30 in Fig. 3A), the interface comprises a pusher coupled to the drive mechanism, the drive mechanism being operable to selectively drive the pusher to abut the plunger to dispense fluid from the barrel (pump actuator 66 can be a DC motor and gearbox assembly or other pump driving mechanism for controlling the plunger [0051]), and the processing device is configured to generate the unloaded measured data during a dispensing fluid movement operation by temporarily retracting the pusher in the barrel (a pump measurement device configured to generate pump measurement related to at least one of each aspirate stroke performed by the pump; processing device configured to analyze pump measurements comprising the pump measurement for each of a plurality of the at least one of the aspirate stroke and the dispense stroke [0007]).

This ensures that piston 30 fully rotates within the sleeve until the coupling pin reaches the end of the helical groove 26 [0050]).
Claim Rejections - 35 USC § 103
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) 3, 5, 8, 11, 12 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zheng et al. (WO2019156852A2, herein Zheng), and further in view of Yodfat et al. (EP 2026862 B1, herein Yodfat)
Regarding claim 3, Zheng as modified disclosed all limitations of claim 1. However, Zheng failed to explicitly disclose wherein the processing device is further configured, during a subsequent fluid movement operation by the pump to
generate unloaded measured data during a portion of the subsequent fluid movement operation wherein the pump does not move fluid,
generate loaded measured data while the pump is moving fluid during the subsequent fluid movement operation,
the measured data being indicative of fluid movement in the pump, and normalize the loaded measured data to the unloaded measured data.
However, Yodfat teaches a processor may be configured to be coupled to the system 1100 and interpret such change of collection location as downstream occlusion, normal pulsating delivery of fluid through the tube 1110, leakage in the tube 1110, or any other condition occurring in the system 1100 that causes change of location [0038]. Interpreting such changes necessarily requires generating measured data representative of fluid movement and processing the data in a standardized or normalized manner to allow meaningful comparison between normal and abnormal operating conditions.
Therefore, it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the invention to modify the fluid delivery device of Zheng with Yodfat to include processing device to monitor and interpret fluid movement conditions. Incorporating such a known data-processing technique amounts to the use of a known technique to improve similar device in a predictable manner (see MPEP 2143.I.C)
Regarding claim 5, Zheng as modified disclosed all limitations of claim 1. However, Zheng failed to explicitly disclose wherein the processing device is further configured to normalize the loaded measured data to the unloaded measured data for each fluid movement operation of the fluid delivery device, or least for a selected subset of fluid movement operations of the fluid delivery device.
However, Yodfat teaches a processor may be configured to be coupled to the system 1100 and interpret such change of collection location as downstream occlusion, normal pulsating delivery of fluid through the tube 1110, leakage in the tube 1110, or any other condition occurring in the system 1100 that causes change of location [0038]. Interpreting such changes necessarily requires processing data representative of fluid movement in a standardized or normalized manner to allow meaningful comparison between normal and abnormal operating conditions.
Therefore, it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the invention to modify the fluid delivery device of Zheng with Yodfat to include processing device to monitor and interpret fluid movement conditions. Incorporating such a known data-processing technique amounts to the use of a known technique to improve similar device in a predictable manner (see MPEP 2143.I.C).
Regarding claim 8, Zheng as modified disclosed all limitations of claim 1. Zheng further disclosed wherein the pump is a syringe-type pump (reciprocating plunger-type pump [0048]) having a barrel as the chamber (chamber 38 in Fig. 3A) and a plunger (pump plunger 30 in Fig. 3A) and the drive mechanism is operable to selectively drive the plunger to dispense fluid from the barrel (as the piston 30 is rotated by the DC motor and gearbox assembly, the piston 30 translates through the sleeve 24, guided by travel of the pin 28 on the piston through a helical slot 26 in the sleeve 24. Once the piston 30 translates fully through the sleeve 24 and completes its aspiration stage or dispensing stage of fluid [0058]), but fails to explicitly disclose the processing device is configured to generate the unloaded measured data before the measured data indicates that fluid pressure or flow rate has begun to increase from driving the plunger by the drive mechanism during the fluid movement operation.
However, Yodfat teaches that the processor can be configured to interpret change of pressure in the fluid delivery tube 810 as either downstream occlusion, leakage in the tube, normal pulsating delivery of the fluid, or any other condition in the tube [0033]. Interpreting changes in pressure necessarily requires continuous monitoring and generation of measured data both before and during pressure changes in order to establish a baseline and detect deviations from normal operation.
Therefore, it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the invention to modify the fluid delivery device of Zheng with Yodfat to include processing device to monitor fluid pressure during operation of the plunger. Applying a known pressure-monitoring and interpretation technique to a similar represents the use of a known technique to improve a similar device in a predictable manner (see MPEP 2143.I.C)
Regarding claim 11, Zheng as modified disclosed all limitations of claim 9. Zheng further disclosed wherein the pump is a syringe-type pump (reciprocating plunger-type pump [0048]) having a barrel as the chamber (chamber 38 in Fig. 3A) and the interface comprises a plunger (pump plunger 30 in Fig. 3A), the drive mechanism being operable to selectively drive the plunger to dispense fluid from the barrel (as the piston 30 is rotated by the DC motor and gearbox assembly, the piston 30 translates through the sleeve 24, guided by travel of the pin 28 on the piston through a helical slot 26 in the sleeve 24. Once the piston 30 translates fully through the sleeve 24 and completes its aspiration stage or dispensing stage of fluid [0058]), but fails to explicitly disclose the processing device is configured to generate the unloaded measured data prior to gathering of loaded measured data by incrementing through a known number of dispense cycles in which the pusher has not yet hit the plunger.
However, Yodfat teaches that the processor can be configured to interpret change of pressure in the fluid delivery tube 810 as either downstream occlusion, leakage in the tube, normal pulsating delivery of the fluid, or any other condition in the tube [0033]. Interpreting pressure changes necessarily requires generating pressure-related data corresponding to fluid delivery events over time, including data associated with repeated dispensing cycles.
Therefore, it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the invention to modify the fluid delivery device of Zheng with Yodfat to include the processing device, because incorporating known data-processing functionality to generate data associated with fluid dispensing is a predictable use of a known technique (see MPEP 2143.I.C).
Regarding claim 12, Zheng as modified disclosed all limitations of claim. Zheng further disclosed wherein the pump is a syringe-type pump (reciprocating plunger-type pump [0048]) having a barrel as the chamber (chamber 38 in Fig. 3A) and the interface comprises a plunger (pump plunger 30 in Fig. 3A), the drive mechanism being operable to selectively drive the plunger to dispense fluid from the barrel (as the piston 30 is rotated by the DC motor and gearbox assembly, the piston 30 translates through the sleeve 24, guided by travel of the pin 28 on the piston through a helical slot 26 in the sleeve 24. Once the piston 30 translates fully through the sleeve 24 and completes its aspiration stage or dispensing stage of fluid [0058]), but fails to explicitly disclose the processing device is configured to generate the unloaded measured data during an aspirating fluid movement operation by manual or externally controlled filling of the barrel via an inlet port to the barrel, and to generate the loaded measured data during the aspirating fluid movement operation by controlling the pump to temporarily retract the plunger within the barrel.
However, Zheng teaches the microcontroller 58 can be provided with an integrated or separate memory device having computer software instructions to actuate, for example, rotation of the sleeve 24 in a selected direction, translational or axial movement of a piston 30 in the sleeve 24 for an aspirate or dispense stroke [0051]. Thus, Zheng teaches active control of plunger movement by a processing device.
Furthermore, Yodfat teaches a processor may be configured to be coupled to the system 1100 and interpret such change of collection location as downstream occlusion, normal pulsating delivery of fluid through the tube 1110, leakage in the tube 1110, or any other condition occurring in the system 1100 that causes change of location [0038]. Interpreting such changes necessarily requires processing data representative of fluid movement in a standardized or normalized manner to allow meaningful comparison between normal and abnormal operating conditions.
Therefore, it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the invention, to modify the fluid delivery device of Zheng to incorporate the data generation and interpretation techniques of Yodfat using the microcontroller of Zheng to both control fluid delivery and generate data about fluid’s behavior. Combining known control capability with known data-processing functionality represents the use of prior art elements according to their established functions, yielding predictable results (see MPEP 2143.I.C)
Regarding claim 17, Zheng disclosed all limitations of claim 1. Zheng further disclosed wherein the pump (reciprocating plunger-type pump [0048]) has a reservoir as the chamber (chamber 38 in Fig. 3A), a plunger (pump plunger 30 in Fig. 3A) and a drive mechanism operable to selectively drive the plunger to dispense fluid from the reservoir (as the piston 30 is rotated by the DC motor and gearbox assembly, the piston 30 translates through the sleeve 24, guided by travel of the pin 28 on the piston through a helical slot 26 in the sleeve 24. Once the piston 30 translates fully through the sleeve 24 and completes its aspiration stage or dispensing stage of fluid [0058]).
However Zheng failed to explicitly disclose and the processing device is configured with baseline data related to a designated waveform of the measured data during fluid movement operations, the waveform having a dead portion therein corresponding to when fluid pressure or rate from driving the plunger by the drive mechanism has not yet begun to increase, the processing device being configured to analyze the measured data using the baseline data to determine when to generate the unloaded measured data during a fluid dispense operation.
Zheng teaches that data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof [0081], which would enable one of ordinary skill in the art to store or transmit fluid delivery data in a conventional manner.
Furthermore, Yodfat teaches a processor may be configured to be coupled to the system 1100 and interpret such change of collection location as downstream occlusion, normal pulsating delivery of fluid through the tube 1110, leakage in the tube 1110, or any other condition occurring in the system 1100 that causes change of location [0038]. Interpreting such changes necessarily requires processing data representative of fluid movement to distinguish normal operation from abnormal events and provide feedback about status of fluid delivery.
Therefore, it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the claimed invention, to modify the fluid delivery device of Zheng with Yodfat to include the processing device is configured with baseline data related to a designated waveform of the measured data during fluid movement operations, the waveform having a dead portion therein corresponding to when fluid pressure or rate from driving the plunger by the drive mechanism has not yet begun to increase, the processing device being configured to analyze the measured data using the baseline data to determine when to generate the unloaded measured data during a fluid dispense operation, because comparing current system operation to an expected reference is a routine and predictable technique for assessing fluid delivery performance (see MPEP 2143.I.C. )
Claim(s) 16 is/are rejected under 35 U.S.C. 103 as being unpatentable
over Zheng et al. (WO2019156852A2, herein Zheng) and further in view of Bazargan et al. (US20140058349A1, herein Bazargan) and Yodfat et al. (EP 2026862 B1, herein Yodfat)
Regarding claim 16, Zheng as modified disclosed all limitations of claim 9. Zheng however fails to explicitly disclose wherein the interface comprises a cam coupled to the drive mechanism, and the processing device is configured to generate the unloaded measured data during a fluid movement operation when a cam follower connected to an actuator for the drive mechanism traverses at least part of a flat portion of the cam resulting in no fluid movement during the fluid movement operation.
However, Bazargan teaches that the gear assembly 236 includes various additional gears and potentially other drive train components (e.g., screws, cams and etc) [0046]. Substituting a cam to a mechanically coupled gear assembly, and incorporating known-data processing functionality to similar device constitutes a routine design choice ((See MPEP 2144.VI.C)
Furthermore, Yodfat teaches a processor may be configured to be coupled to the system 1100 and interpret such change of collection location as downstream occlusion, normal pulsating delivery of fluid through the tube 1110, leakage in the tube 1110, or any other condition occurring in the system 1100 that causes change of location [0038]. Interpreting such changes necessarily requires processing data representative of fluid movement in a standardized or normalized manner to allow meaningful comparison between normal and abnormal operating conditions.
Therefore it would have been obvious to one of ordinary skill in the art, prior to the effective filing date of the invention, to modify the fluid delivery device of Zheng with Bazargan and Yodfat to include a cam coupled to the drive mechanism, and the processing device is configured to generate the unloaded measured data during a fluid movement operation when a cam follower connected to an actuator for the drive mechanism traverses at least part of a flat portion of the cam resulting in no fluid movement during the fluid movement operation, because combining known mechanical drive components and known data-processing techniques represents the use of prior art elements according to their established functions, yielding predictable results (See MPEP (see MPEP 2143.I.C).
