Office Action

§103 §112
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 . INFORMATION DISCLOSURE STATEMENT The information disclosure statement (IDS) submitted on 20 December 2023 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the IDS has been considered by the Examiner herein. CLAIM STATUS Claims 1-23 were originally filed. Claims 1-23 are currently pending and have been examined herein. INITIAL REMARKS Applicant is reminded that in order to be entitled to reconsideration or further examination, the Applicant or patent owner must reply to the Office action. The reply by the Applicant or patent owner must be reduced to a writing which distinctly and specifically points out the supposed errors in the examiner' s action and must reply to every ground of objection and rejection in the prior Office action. The reply must present arguments pointing out the specific distinctions believed to render the claims, including any newly presented claims, patentable over any applied references. If the reply is with respect to an application, a request may be made that objections or requirements as to form not necessary to further consideration of the claims, be held in abeyance until allowable subject matter is indicated. The Applicant's or patent owner's reply must appear throughout to be a bona fide attempt to advance the application or the reexamination proceeding to final action. A general allegation that the claims define a patentable invention without specifically pointing out how the language of the claims patentably distinguishes them from the references does not comply with the requirements of this section. Should the Applicant believe that a telephone conference would expedite the prosecution of the instant application, Applicant is invited to call the Examiner. 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 21 is rejected under 35 U.S.C. § 112(b) or 35 U.S.C. § 112 (pre-AIA ), 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. Re claim 21, Applicant recites a first instance of the limitation, “the respective sensor installed…”. However, Applicant lacks antecedent basis for this limitation, thereby rendering it indefinite. More specifically, claim 1, from which claim 21 directly depends, does not require a sensor to be installed in the measuring chamber. It only requires an “opening configured to enable” such installation. 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. Claims 1-7, 11-19, and 21-23 are rejected under 35 U.S.C. § 103 as being unpatentable over Jugert et al, US20200173974 (“JUGERT”) in view of Leuthold et al., WO2019243063A1 (“LEUTHOLD”). Re claim 1, JUGERT discloses a modular measuring cell for analytical technology in bioprocess analysis comprising two or more successively arranged and interconnected individual modules [0030], wherein the individual modules are each: configured as a flow-through measuring cell for a fluid including an inflow opening and an outflow opening, which are assigned to a first and a second outer surface of the individual module, respectively [0030]; include a flow channel having a measuring chamber between the inflow and outflow openings [0030]; include first connecting elements with an axisymmetrical arrangement on the first and second outer surfaces [Fig.2 and associated text]; and include at least one further opening configured to enable installation of a sensor in the measuring chamber, the sensor configured to measure chemical and/or physical properties of the fluid flowing through the measuring cell [0030] JUGERT fails to explicitly disclose wherein a uniform adapter is arranged between two successive individual modules, which adapter includes a fluid-connecting passage opening and is configured to connect the flow channels of the successive individual modules to form a main line channel, wherein the adapter includes first and second opposing outer surfaces, which include second connecting elements having an axisymmetrical arrangement, wherein the first and second connecting elements are complementary to each other, and wherein each individual module is configured to be connected with respect to an adjacent individual module by a predetermined number of orientations about an axis of symmetry However, LEUTHOLD, in the same or similar field of endeavor, teaches a modular measuring cell system [Abstract], wherein a uniform adapter is arranged between two successive individual modules, which adapter includes a fluid-connecting passage opening and is configured to connect flow channels of the successive individual modules to form a main line channel [Fig.2c and associated text], wherein the adapter includes first and second opposing outer surfaces, which include second connecting elements having an axisymmetrical arrangement, wherein the first and second connecting elements are complementary to each other [Fig.2c and associated text], and wherein each individual module is configured to be connected with respect to an adjacent individual module by a predetermined number of orientations about an axis of symmetry [Fig.2c and associated text] Furthermore, it would have been obvious to one of ordinary skill in the art, at the time of filing of the instant invention, to modify the modular cell system of JUGERT to include to include the particular adapter element of LEUTHOLD. One would have been motivated to do so in order to enable a simpler and more compact biopharmaceutical processing system (see LEUTHOLD [Description, Para.3]. Further still, the Supreme Court in KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007) provided that combining prior art elements according to known methods to yield predictable results may render a claimed invention obvious over such combination. Here, LEUTHOLD merely teaches that it is well-known to use a uniform adapter to connect modular measuring cells for use in bioprocess analysis. Since both JUGERT and LEUTHOLD disclose similar modular measuring cell systems, one of ordinary skill in the art would recognize that the combination of elements here has previously been executed according to known methods, thereby evidencing that such combination would yield predictable results. Re claim 2, JUGERT/LEUTHOLD renders obvious the modular measuring cell of claim 1, as discussed above. JUGERT fails to explicitly disclose wherein: the first outer surface of an individual module at an inflow-side end of the main line channel is configured to be connected to a first port; the second outer surface of an individual module at an outflow-side end of the main line channel is configured to be connected to a second port, each connection in at least a liquid-tight or gas-tight manner; wherein the first and second ports each include: a first port element or a second port element, which is of the same or different configuration; and a uniform base element including a base surface which faces an outer surface of one of the individual modules and includes third connecting elements with an axially symmetric arrangement; and wherein the first connecting elements of each individual module and the third connecting elements of the base surface are complementary to each other However, LEUTHOLD, in the same or similar field of endeavor, teaches a modular measuring cell system [Abstract] wherein: the first outer surface of an individual module at an inflow-side end of the main line channel is configured to be connected to a first port [Fig.2c and associated text]; the second outer surface of an individual module at an outflow-side end of the main line channel is configured to be connected to a second port, each connection in at least a liquid-tight or gas-tight manner [Fig.2c and associated text]; wherein the first and second ports each include: a first port element or a second port element, which is of the same or different configuration [Fig.2c and associated text]; and a uniform base element including a base surface which faces an outer surface of one of the individual modules and includes third connecting elements with an axially symmetric arrangement [Fig.2c and associated text]; and wherein the first connecting elements of each individual module and the third connecting elements of the base surface are complementary to each other [Fig.2c and associated text] Furthermore, it would have been obvious to one of ordinary skill in the art, at the time of filing of the instant invention, to modify the modular cell system of JUGERT to include to include the particular surface elements of LEUTHOLD. One would have been motivated to do so in order to enable a simpler and more compact biopharmaceutical processing system (see LEUTHOLD [Description, Para.3]. Further still, the Supreme Court in KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007) provided that combining prior art elements according to known methods to yield predictable results may render a claimed invention obvious over such combination. Here, LEUTHOLD merely teaches that it is well-known to use this particular configuration for use in a modular bioprocess analysis system. Since both JUGERT and LEUTHOLD disclose similar modular measuring cell systems, one of ordinary skill in the art would recognize that the combination of elements here has previously been executed according to known methods, thereby evidencing that such combination would yield predictable results. Re claim 3, JUGERT/LEUTHOLD renders obvious the modular measuring cell of claim 2, as discussed above. JUGERT fails to explicitly disclose wherein the connection between two individual modules connected via the adapter and/or between an individual module and a first or second port element is non-detachable and form-fitting However, LEUTHOLD, in the same or similar field of endeavor, teaches a modular measuring cell system [Abstract] wherein, the connection between two individual modules connected via the adapter and/or between an individual module and a first or second port element is non-detachable and form-fitting [Fig.2c and associated text]; Furthermore, it would have been obvious to one of ordinary skill in the art, at the time of filing of the instant invention, to modify the modular cell system of JUGERT to include to include the particular adapter element of LEUTHOLD. One would have been motivated to do so in order to enable a simpler and more compact biopharmaceutical processing system (see LEUTHOLD [Description, Para.3]. Further still, the Supreme Court in KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007) provided that combining prior art elements according to known methods to yield predictable results may render a claimed invention obvious over such combination. Here, LEUTHOLD merely teaches that it is well-known to use this particular configuration for use in a modular bioprocess analysis system. Since both JUGERT and LEUTHOLD disclose similar modular measuring cell systems, one of ordinary skill in the art would recognize that the combination of elements here has previously been executed according to known methods, thereby evidencing that such combination would yield predictable results. Re claim 4, JUGERT/LEUTHOLD renders obvious the modular measuring cell of claim 2, as discussed above. JUGERT fails to explicitly disclose wherein each individual module is connected to the adapter and/or the first or second port element via at least one of: a form-fitting axial latching about a longitudinal axis of the measuring cell, which is enabled by one or more latching elements; a fixation enabled by the first connecting elements with the second or third connecting elements; and an adhesive bond or a material connection by laser welding However, LEUTHOLD, in the same or similar field of endeavor, teaches a modular measuring cell system [Abstract] wherein, each individual module is connected to the adapter and/or the first or second port element via at least one of: a form-fitting axial latching about a longitudinal axis of the measuring cell, which is enabled by one or more latching elements; a fixation enabled by the first connecting elements with the second or third connecting elements; and an adhesive bond or a material connection by laser welding [Fig.2c and associated text]; Furthermore, it would have been obvious to one of ordinary skill in the art, at the time of filing of the instant invention, to modify the modular cell system of JUGERT to include to include the particular adapter element of LEUTHOLD. One would have been motivated to do so in order to enable a simpler and more compact biopharmaceutical processing system (see LEUTHOLD [Description, Para.3].

Re claim 10, JUGERT/LEUTHOLD/OFFICIAL NOTICE renders obvious the modular measuring cell of claim 9, as discussed above. JUGERT further discloses wherein an overall form of each individual module, including the first and second outer surfaces, is configured in a cube-like or cuboid-like shape [Fig.2 and associated text] Re claim 20, JUGERT/LEUTHOLD renders obvious the modular measuring cell of claim 1, as discussed above. JUGERT/LEUTHOLD fails to explicitly disclose wherein the individual modules, the adapter, and first and second ports connectable to the individual modules are configured for single use and are composed predominantly or substantially entirely of plastic, wherein the plastic is a radiation-resistant and/or hot steam-sterilizable plastic, or wherein the plastic is a biocompatible, radiation-resistant, and/or hot steam-sterilizable plastic However, the Examiner takes OFFICIAL NOTICE that configuring a modular measuring cell system for single-use using these particular materials is old and well-known; Furthermore, it would have been obvious to one of ordinary skill in the art, at the time of filing of the instant invention, to modify the modular cell system of JUGERT/LEUTHOLD to include to include this particular structure. One would have been motivated to do so in order to enable a simpler and more compact biopharmaceutical processing system (see LEUTHOLD [Description, Para.3]. Further still, the Supreme Court in KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007) provided that combining prior art elements according to known methods to yield predictable results may render a claimed invention obvious over such combination. Here, the Examiner’s assertion merely teaches that it is well-known to use this particular structure for use in a modular bioprocess analysis system. Since both JUGERT/LEUTHOLD disclose similar modular measuring cell systems and the Examiner’s assertion is well-known to be used in these systems, one of ordinary skill in the art would recognize that the combination of elements here has previously been executed according to known methods, thereby evidencing that such combination would yield predictable results. RELEVANT PRIOR ART The Examiner would like to make Applicant aware of prior art references, not relied upon in this action, but pertinent to Applicant’s disclosure. They are as follows: US20190025239, Robl et al. – modular measuring system CN110650797A, Lin et al. – modular chemical reaction system CONCLUSION Any inquiry concerning this communication or earlier communications from the examiner should be directed to THOMAS M HAMMOND III whose telephone number is 571-272-2215.
