Claim Rejections - 35 USC § 112(b)- Indefiniteness
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.
Claims 8, 26, and 33-36 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention.
Claim 8 contains the trademark/trade name “Hoechst” stains. Where a trademark or trade name is used in a claim as a limitation to identify or describe a particular material or product, the claim does not comply with the requirements of 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. See Ex parte Simpson, 218 USPQ 1020 (Bd. App. 1982). The claim scope is uncertain since the trademark or trade name cannot be used properly to identify any particular material or product. A trademark or trade name is used to identify a source of goods, and not the goods themselves. Thus, a trademark or trade name does not identify or describe the goods associated with the trademark or trade name. In the present case, the trademark/trade name is used to identify/describe a genus of fluorescent dye molecules with distinct structures and spectral properties. Accordingly, the identification/description is indefinite.
Claim 26 recites a “closed form shape is elliptic or circular and… has a diameter of between 3 microns and 90 microns.” Ellipses do not have a single diameter, but rather a major and minor axis. It is unclear whether the recited “diameters” are intended to limit one or both of these dimensions (i.e. a] any ellipse having a major axis between 3 microns and 90 microns and a minor axis of any dimension shorter than the major axis length OR b] any ellipse having a minor axis between 3 microns and 90 microns and a major axis of any dimension longer than the minor axis, OR c] any ellipse wherein both of the minor and major axis are between 3 microns and 90 microns in length). Therefore, the metes and bounds of the genus of elliptic closed-form shapes recited by claim 26 are unclear.
Claim 33 recites “a first detectable marker… is indicative of… a cell nucleus, and… using a measured intensity of the first detectable marker… to determine… [an] estimate of a number of cells…”. It is unclear whether this claim language is intended to limit the type of cells that may be detected/quantified by the claimed method because the recited relationship between a measured intensity of a cell nuclear marker (e.g. a nuclear protein such as a histone or DNA such as DAPI staining) does not correlate with cell number for all cell types. For example, a) multinucleate cells such as osteoclasts, skeletal and cardiac muscle cells, syncytiotrophoblast, b) anucleate cells such as mammalian erythrocytes, or c) populations of cells having diverse ploidy status (i.e. tumor cells having diverse aneuploidies or exhibiting micronuclei). It is unclear whether methods comprising determining an estimate of a number of cells based upon the measured intensity of a detectable nuclear marker in a capture region that may comprise multiple cells of diverse lineage or identity or cancer status is intended to encompass embodiments wherein the multiple cells comprise multinucleate, anucleate, or aneuploid cells.
Claim 35 recites “a pattern of abundance of [a] second detectable marker [that is indicative of the presence of a cell membrane]… to validate… the… estimate of the number of cells [based upon the abundance of a first marker that is indicative of the presence of a cell nucleus]”. Neither the claims nor the specification define the claim term “pattern of abundance”. It is unclear whether the claim requires: a) comparing a ratio of the intensities of the first and second detectable markers summed over each of the capture spots (e.g. a ratiometric pattern of total “nuclear” signal to total “cell membrane” signal for a given capture spot, b) a spatial pattern of the second detectable marker relative to the first detectable marker within each of the capture spots (e.g. “rings” of second marker signal surrounding first marker signal), or c) something else.
Claim 36 recites “the method of claim 1, further comprising the display of all or the portion of the first spatial dataset and the corresponding all or the portion of the second dataset co-registered to each other characterizes a biological condition in a subject.” Claim 36 does not appear to positively recite any method steps in addition to those recited by claim 1, which recites a step of “…displaying all or a portion of the first spatial dataset and a corresponding all or a portion of the second spatial dataset co-registered to each other…”. Rather, it appears that the further recitation of “characterizes a biological condition in a subject” constitutes an intended result. Furthermore, the claim does not define how the display of the two datasets characterizes a biological condition in a subject or provide any positively recited method steps to accomplish the recited goal of “characteriz[ing] a biological condition”. Regarding intended results, In Hoffer v. Microsoft Corp., 405 F.3d 1326, 1329, 74 USPQ2d 1481, 1483 (Fed. Cir. 2005), the court held that when a "‘whereby’ clause states a condition that is material to patentability, it cannot be ignored in order to change the substance of the invention." Id. However, the court noted that a "‘whereby clause in a method claim is not given weight when it simply expresses the intended result of a process step positively recited.’" Id. (quoting Minton v. Nat’l Ass’n of Securities Dealers, Inc., 336 F.3d 1373, 1381, 67 USPQ2d 1614, 1620 (Fed. Cir. 2003)). In the present case, the claim language “characterizes a biological condition…” does not state a condition material to patentability or provide any structure or method steps in addition to the “display [of the data]” recited by claim 36 and claim 1, upon which claim 36 depends. It is the position of the examiner that the instant claim language instead raises a question as to the limiting effect of the claim language similar to the non-limiting example “whereby” clauses described in M.P.E.P. 2111.04(I).
Claim 34 is rendered indefinite because it depends from, and thus includes the indefinite limitations of claim 33.
Claim Rejections - 35 USC § 112(d)
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claim 36 is rejected under 35 U.S.C. 112(d) as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends.
In the instant case, as described in the 112(b) rejection above, claim 36 does not positively recite any method steps or structural limitations in addition to those already recited by claim 1, upon which claim 36 depends. Therefore, claim 36 does not further limit the subject matter of the claim upon which it depends.
Applicant may cancel the claim, amend the claim to place the claim in proper dependent form, rewrite the claim in independent form, or present a sufficient showing that the dependent claim complies with the statutory requirements.

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.
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(s) 1-20, 23-26, 29-32, and 36 are rejected under 35 U.S.C. 103 as being unpatentable over Mellen et al., US 2021/0097684 A1 (filed September 30, 2020 and published April 1, 2021) in view of Weisenfeld et al., US 2021/0150707 A1 (filed November 18, 2020 and published May 20, 2021).
Regarding claims 1-20, 25, 26, 29-32, and 36, the teachings of Mellen et al. are described in the rejection under 35 U.S.C. 102(a)(1) and 102(a)(2) in detail above.
Regarding claims 23 and 24, Mellen et al. teach capture spots have a diameter of 100 µm or less and are distributed with a center to center distance of 200 µm or less, and in particular examples, have a diameter of 55 µm and a center to center distance of 100 µm).
Mellen et al. do not teach capture spots having a diameter of 2 µm (i.e. contained within a 2 micron by 2 micron square or capture spots having a center to center distance of between 2 microns and 8 microns (i.e. having a diameter between 2 and 8 microns, assuming capture spots do not overlap).
However, Weisenfeld et al. teach similar methods of spatial analysis of tissue samples comprising preparing a tissue slice on an array of capture spots, imaging the tissue and/or array using fluorescent and/or bright field microscopy for multiple detectable markers, preparing spatially indexed, UMI-containing, next-generation sequencing libraries from nucleic acids released by the tissue onto the array of capture spots, sequencing the libraries, and overlaying the detectable marker signals and the sequencing data for each capture spot (Weisenfeld et al., figure 3A, 3B, and 12)

Weisenfeld et al. further teach that the capture spots on the array can be a variety of sizes including, a diameter no larger than 2 microns (i.e. fitting within a 2 micron by 2 micron square, or having a center to center distance between 2 microns and 8 microns) (Weisenfeld et al., paragraph 0455).
Weisenfeld et al. further teach that resolution of data collected on such arrays of capture spots is dependent upon the diameter, and thus density, of the capture spots, wherein “low resolution arrays” have capture spots with 20 micron diameters or greater (i.e. Weisenfeld et al. describe the arrays taught by Mellen et al. as “low resolution”) and “high resolution arrays” have capture spots with a diameter of about 1 micron to about 10 microns. Weisenfeld additionally suggests “resolution of an array can be improved by constructing an array with smaller capture spots” (Weisenfeld et al., paragraphs 0473-0475).
Therefore, it would have been prima facie obvious prior to the effective filing date of the claimed invention for one of ordinary skill in the art to have modified the methods for analyzing tissue samples taught by Mellen et al. with the teachings and suggestions of Weisenfeld et al. to increase the resolution of the capture array by decreasing the diameter of each individual capture spot to between 1 and 10 microns, wherein smaller diameters correspond to higher expected resolution of analytes (i.e. mRNA expression) on a given biological sample. Therefore, the ordinary artisan would have been motivated to select the smallest practicable diameter capture spots in order to predictably attain the highest possible resolution spatial gene expression data by the methods taught by Mellen et al. and Weisenfeld et al. (i.e. 1 micron diameter capture spots).
Claim(s) 1-20, 25, 26, and 29-36 are rejected under 35 U.S.C. 103 as being unpatentable over Mellen et al., US 2021/0097684 A1 (filed September 30, 2020 and published April 1, 2021) in view of Kjaerulff et al., US 2012/0045757 A1 (published February 23, 2012).
Regarding claims 1-20, 25, 26, 29-32, and 36, the teachings of Mellen et al. are described in the rejection under 35 U.S.C. 102(a)(1) and 102(a)(2) in detail above.
Regarding claims 33 and 34, Mellen et al. teach computationally segmenting probe spots based upon different combinations of fluorescent markers present in the corresponding images, identification of tissue structures, and/or identification of pathology (Mellen et al., paragraph 0115), and that the samples can be stained with a variety of DNA-binding (i.e. indicative of a nucleus) dyes such as DAPI.
Mellen et al. do not teach using a measured intensity of a detectable marker that is indicative of the presence of a nucleus to estimate a number of cells in each capture spot.
However, Kjaerulff et al. teach various methods for automatic detection of fluorescence signals from a sample (Kjaerulff et al., paragraph 0028-0029) comprising staining nuclei with DAPI and viable cells with DACM (N-(7-dimethylamino-4-methyl-3-coumarinyl)-maleimide) (a dye that reacts with thiols found in proteins in living cells (i.e. cells with intact membranes) (Kjaerulff et al., paragraph 0011 and 0015). Kjaerulff et al. further teach that automated methods comprising staining cell nuclei and viable cells having intact membranes provide for rapid detection and quantitation of live cells (Kjaerulff et al., paragraph 0146).
Therefore, it would have been prima facie obvious prior to the effective filing date of the claimed invention for one of ordinary skill in the art to have combined the methods taught by Mellen et al., comprising automated brightfield and fluorescent imaging of tissues (including nuclear stains such as DAPI or Hematoxylin and cytosolic stains such as Eosin and cell-membrane associated stains such as fluorescently-labeled anti-CD3 antibodies) associated with specific capture spots with the methods taught by Kjaerulff et al. comprising automatically detecting and counting intact cells (having nuclei stained with a DNA binding dye and intact membranes) on a substrate.
The ordinary artisan would have been motivated to count the number of cells per capture spot in the method taught by Mellen et al. by the cell-staining methods taught by Kjaerulff et al. because the ordinary artisan would have recognized the benefits of a) normalizing measured mRNA expression values to a concrete count of the number of cells from which the mRNA molecules are derived, b) excluding background counts from capture spots that do not contain a cell (i.e. due to diffusion of mRNA from neighboring spots or contamination), and/or c) determining which capture spots are representative of a single cell type (i.e. a cancer cell) within a mixed population of cells (i.e. a section of a tumor sample).
Regarding claim 35, Kjaerulff et al. teach that DNA-binding dyes such as propidium iodide, ethidium bromide, and DAPI stain DNA in nuclei in intact cells as well as in dead or dying cells (Kjaerulff et al., paragraph 0009).
Therefore, it would have been prima facie obvious prior to the effective filing date of the claimed invention for one of ordinary skill in the art to have combined the methods taught by Mellen et al. for quantitative, spatial assessment of mRNA expression from discrete cells or cell populations associated with a particular capture spot with the methods taught by Kjaerulff et al. for determining whether a particular cell or cells are viable (i.e. stained with a DNA-binding dye such as DAPI and a dye indicator of intact cell membranes such as DACM) (i.e. determining a count of cells per capture spot based on detection of nuclei AND an intact membrane).
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used.

Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 8, and 15 of U.S. Patent No. 11,514,575 B2, (herein referred to as ‘575). Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of ‘575 recite all of the method steps recited by the present claim 1.
Claim 1 of ‘575 recites a method comprising steps using a computer system to: for each capture spot in an array of capture spots, obtaining one or more spatial projections of a biological sample, obtaining one or more two-dimensional images of a tissue section from the biological sample overlaid on a substrate having the array of capture probes, obtaining a corresponding set of discrete attribute values obtained from two-dimensional spatial sequencing of the tissue section, wherein each attribute value is for a different loci (i.e. mRNA molecule counts in each capture spot); obtaining cluster assignments of each capture spot based on the two-dimensional images and the attribute values, and displaying pixel values of all or a portion of the two-dimensional images overlaid with each capture spot (‘575, claim 1). Claim 8 of ‘575, which depends on claim 1, further recites the two-dimensional images comprise bright-field images and immunohistochemistry images taken at different wavelengths (i.e. emission images of detectable immunohistochemistry markers). Finally, claim 15 of ‘575, which depends on claim 1, further recites that each of the “loci” for which “attribute values” are collected, recited by claim 1, are each a respective gene, and that each attribute value is a count of unique molecular indices that also map to a respective gene (i.e. the attribute values assigned to each capture spot are representations of numbers of molecules of a nucleic acid originating from the tissue sample).
Therefore, the claims of ‘575 recite all of the positively recited method steps recited by the present claim 1.
Claim 1 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 and 64 of copending Application No. 16/951,864 (herein referred to as ‘864). Although the claims at issue are not identical, they are not patentably distinct from each other because claims 1 and 64, which depends from claim 1, of ‘864 claims all of the recited method steps of the present claim 1.
Claim 1 of ‘864 recites steps comprising: placing a sample on a substrate comprising fiducial markers and at least 1000 capture spots, obtaining one or more images of the sample, obtaining sequence reads from the capture spots wherein each capture probe a capture spot comprises a unique spatial barcode associated with a particular location on the substrate, and providing a composite representation of the one or more images aligned to the capture spots and a representation of the sequence reads at each position within the one or more images that maps to a capture spot (i.e. spatially displaying the two datasets co-registered by the plurality of spatial barcodes) (‘864, claim 1).
Claim 64 depends from claim 1 and further claims that the one or more images comprises brightfield or fluorescence images.
Therefore, the claims of ‘864 encompass all of the claimed method steps recited by the present claim 1.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
