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 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 –
(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) 1-5, 9-12, and 14-16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Frederickson et al (US 20080293157 A1; hereinafter “Fredrickson”; already of record on IDS filed 8/31/2021).
Regarding claim 1, Fredrickson teaches an apparatus for the implementation of in vitro biocompatibility tests (Fredrickson; Abstract), said apparatus comprising:
at least one sample being disposed on a surface of a base plate or in which the at least one sample forms a surface or a surface region of the base plate (Fredrickson; Fig. 3; para [47]; The base 122 includes an upper face 124 (FIG. 3) to which the frame 156 is coupled…The frame 156 defines a recessed portion 159 having a counter surface 158 that is configured to receive multiple specimens 134; the examiner interprets the base plate to include both the frame and the base 122) and a receiving element having at least one through-hole having ends with a first and second openings placed on the at least one sample such that the first opening of the through-hole (Fredrickson; Fig. 3; para [48]; the gasket 140 disposed on the frame 156 over the specimens 134. The gasket 140 defines multiple openings 162; examiner interprets the through holes to the first opening as the end that is directed/faced towards the base/frame, and the second opening as the end that is directed/faced towards cover/top) is disposed pointing in a direction of the base plate (Fredrickson; Fig. 3, 6; examiner notes that the opening is over the base plate), and the at least one through-hole being disposed pointing on the at least one sample (Fredrickson; Fig. 6; para [48]; the gasket 140 disposed on the frame 156 over the specimens 134),
the at least one through-hole having a hollow space above the sample forming a cavity (Fredrickson; Fig. 6; examiner notes that the space in the through-hole is hollow thus holding the sample as seen in Fig. 6), and
the receiving element being formed solely from or with an elastically deformable material (Fredrickson; Fig. 1; para [44]; the gasket 40 can each be formed with various materials, preferably materials that can be sterilized for repeated use, such as silicone rubber; examiner notes that the gasket 40 shown in Fig. 1, is the general principles of the invention and later discussed as gasket 140);
a cover element (Fredrickson; Fig. 3; para [46]; top plate 128) being placed and fixed directly on the receiving element such that pressure force acts on the receiving element which creates a partial deformation of the receiving element and produces a fluid-impermeable closure of the first opening (Fredrickson; Fig. 4, 5, 6; para [48, 49]; the gasket 140 provides a sealing fit between the top plate 128 and the specimens 134… A nut 154 can be threaded on to each pin 152 to couple the top plate 128 to the base 122, sandwiching the gasket 140 and the specimens 134 there between; examiner notes that the receiving element is partially deformed upon screwing of the nut because material of the gasket is silicone rubber), and
on the base plate and on the cover element, closure elements being formed with which, when brought into engagement, a form fit connection of the base plate and the cover element, and the pressure force exertion on the receiving element are provided (Fredrickson; Fig. 3, 5, 7; para [35, 48, 49]; the test apparatus 20 can include a gasket 40 to provide a sealing fit between the top plate 28…the gasket 140 defines multiple openings 162 that align with, and correspond to, apertures 150 of the top plate 128 when the top plate 128 is coupled to the base 122…the top plate 128 is removably coupled to the base 122 includes a set of pins 152…the coupling mechanism by which the top plate 128 is removably coupled to the base 122 includes a set of pins 152; The examiner notes that the top plate is screwed onto the base through the pins, thus a force is exerted on the receiving element when the plate is secured),
the closure elements including an edge on an end-side of the cover element and a lower edge of the base plate (Frederickson; Fig. 3). The Examiner interprets the closure elements as the set of pins which couple to the nut. Thus, the nut comprises an edge on the end side of the cover element and the pins have an edge connected to the base plate.
Regarding claim 2, Fredrickson teaches the apparatus according to claim 1, wherein the elastically deformable receiving element is formed from a biocompatible and/or sterilisable material (Fredrickson; Fig. 1; para [44]; the gasket 40 can each be formed with various materials, preferably materials that can be sterilized for repeated use, such as silicone rubber).
Regarding claim 3, Fredrickson teaches the apparatus according to claim 1, wherein the receiving element is formed from or with the elastically deformable material has a Shore hardness in the range of 30 to 50 (Fredrickson; Fig. 1; para [44]; the gasket 40 can each be formed with various materials, preferably materials that can be sterilized for repeated use, such as silicone rubber). While Fredrickson does not address a Shore hardness in the range of 30 to 50, it has been determined that where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In the current case, the receiving element can consist for example of silicone. Absent persuasive evidence that the receiving element of the instant claims and the gasket made of silicone rubber of Fredrickson are different, the prior art is considered to have the same properties with respect to Shore hardness in the range of 30 to 50 as that is claimed. MPEP § 2112.01 (I-IV).
Regarding claim 4, Fredrickson teaches the apparatus according claim 1, wherein the at least one sample is fixed in a form-fit area on the surface of the base plate (Fredrickson; Fig. 6; para [47]; the frame 156 with specimens 134 disposed within the recessed portion 159).
Regarding claim 5, Fredrickson teaches the apparatus according claim 1, wherein at least one opening located in the cover element (Fredrickson; Fig. 3; para [46]; the top plate 128 includes an upper face 130, a lower face 132, and defines multiple apertures 150 extending from the upper face 130 to the lower face 132) connecting at least partially to the second opening of a respective through-hole of the receiving element which second opening is disposed in a direction of the cover element (Fredrickson; Fig. 3, 6; para [48]; The gasket 140 defines multiple openings 162 that align with, and correspond to, apertures 150 of the top plate 128). As previously noted, the examiner interprets the side which contact/face the top plate as the second opening of the through hole, thus partially connecting the receiving element and the cover element.
Regarding claim 9, Fredrickson teaches the apparatus according claim 1, wherein corresponding to cavities in cell culture research (Fredrickson; para [61]; the sample material can be, for example, a biological material, a non-biological material, a fluid, a dye, a cell), the cover element and the receiving element adapted thereto are modularly exchangeable (Fredrickson; para [35]; the gasket 40 can be removably disposed between the frame 56 and the top plate 28). Examiner notes that the cover element and receiving element are capable of being adapted modularly as both structures may be removed or provided without the other.
Regarding claim 10, Fredrickson teaches the apparatus according claim 1, wherein the at least one sample is inserted in a receiving space configured in the base plate (Fredrickson; Fig. 3; para [47]; the frame 156 defines a recessed portion 159 having a counter surface 158 that is configured to receive multiple specimens 134), and after placing the receiving element with the first opening of one or more through-holes on the sample, the respective sample does not contact an inner wall of an adjacent through-hole of the receiving element (Fredrickson; Fig. 6; para [48]; When the top plate 128 is coupled to the base 122, multiple wells 164 are defined by the apertures 150 of the top plate 128 and each of the specimens 134. Thus, each specimen 134 is associated with multiple different apertures 150. The gasket 140 provides a sealing fit between the top plate 128 and the specimens 134, providing a seal at a bottom portion of the wells 164).
Regarding claim 11, Fredrickson teaches the apparatus according claim 1, wherein a plurality of the through-holes are configured or disposed in assigned groups (Fredrickson; Fig. 6). The through-hole can be grouped based on the row/column of the top plate.
Regarding claim 12, Fredrickson teaches the apparatus according claim 1, wherein the receiving element is retained in a form-fit with the base plate or the cover element (Fredrickson; Fig. 2, 5, 6; para [48]; the gasket 140 provides a sealing fit between the top plate 128 and the specimens 134).
Regarding claim 14, Fredrickson teaches the apparatus according claim 1, wherein on the base plate, at least one opening is present for guiding objects in and out (Fredrickson; para [43]; a recessed portion similar to the frame 56 such that the specimens 34 can be placed within the reader tray 46…transporting the specimens 34 from, for example, the test apparatus 20 to a spectrophotometer or other device for further evaluation).
Regarding claim 15, Fredrickson teaches the apparatus according claim 1, wherein the cover element and/or a closing cover which allow a gas exchange with an ambient atmosphere are present on the cover element or on a closing cover (Fredrickson; Fig. 6; para [46]; The top plate 128 includes an upper face 130, a lower face 132, and defines multiple apertures 150). The system is an open system comprising apertures on the top plate which allows for gases from the ambient atmosphere to be present/exchanged.
Regarding claim 16, Fredrickson teaches the apparatus according claim 1, wherein a plurality of different samples are disposed on a surface of a base plate or various sample respectively form a surface or a surface region on the base plate (Fredrickson; Fig. 6; para [50]; one or more test or sample materials 142 can be disposed within one or more of the wells 164 to test the effects of the sample material(s) 142 on the specimen(s) 134). Regarding claim 16, these limitations are directed to the intended use of the apparatus and/or the manner of operating the apparatus, all the structural limitations of the claim has been disclosed by Fredrickson and the apparatus of Fredrickson is capable of “various sample respectively form a surface or a surface region of the base plate”. As such, it is deemed that the claimed apparatus is not differentiated from the apparatus of Fredrickson (see MPEP §2114).
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 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Fredrickson in view of Mainquist et al (US 20040141887 A1; hereinafter “Mainquist”; already of record).
Regarding claim 13, Fredrickson teaches the apparatus according claim 1, with the closing element.
Fredrickson does not teach further comprising a closing cover is located on the cover element, the closing cover allowing a gas exchange with an environment, for a defined prescribable positioning or orientation on a surface of the closing cover or the cover element, with at least one construction element being present for a form-fit orientation.
However, Mainquist teaches an analogous art of an apparatus for fluidily separating substrate surface (Mainquist; Abstract) comprising a closing cover (Mainquist; Fig. 1B, 9A; para [99]; sealing member 126) is located on the cover element (Mainquist; Fig. 1B; para [71]; sealing member 126 is mated with, e.g., separating member 102, and when substrates 108 are supported by supporting member 106) the closing cover allowing a gas exchange with an environment, (Mainquist; Fig. 9A; para [99]; sealing member 126 includes recessed grooves 130; The system is an open system comprising grooves on the sealing member 126 which allows for gases from the ambient atmosphere to be present/exchanged), for a defined prescribable positioning or orientation on a surface of the closing cover or the cover element (Mainquist; Fig. 9A; para [101]; sealing member 126 of FIG. 9A includes alignment features 154 that align sealing member 126 with, e.g., separating member 102), with at least one construction element being present for a form-fit orientation (Mainquist; para [99]; an apparatus of the invention further includes at least one sealing component (e.g., a gasket or the like) disposed between sealing and separating members). It would have been obvious to one of ordinary skill in the art by the effective filing date to have modified the apparatus of Fredrickson to comprise the closing cover as taught by Mainquist, because Mainquist teaches that the sealing member seals the apparatus (Mainquist; para [71]) and minimizes evaporation and the risk of contamination during processes or storage (Mainquist; para [102]).
Response to Arguments
Applicant’s arguments filed, 6/24/2026, have been fully considered. The arguments are not found to be persuasive, and the non-persuasive arguments are addressed below.
In the Applicant’s arguments, on page 7-9, the Applicant argues Frederickson fails to teach the limitation “the closure elements including an edge on an end-side of the cover element and a lower edge of the base plate”. The Examiner interprets the closure elements as the set of pins which couple to the nut. Thus, the nut comprises an edge on the end side of the cover element and the pins have an edge connected to the base plate as depicted in Fig. 3. Further, Applicant’s arguments regarding the closure elements of Frederickson not being part of the base or cover is not persuasive. The closure elements as recited in the claims is interpreted to be separate structures and is not limited to a structure integrated with the base or cover element.
In the Applicant’s arguments, on page 10-11, the arguments regarding the dependent claim 13 merely refer back to the teachings of the references not meeting independent claim 1. However, the arguments regarding claim 1 are addressed above.
