BARBEAU and JOHN S. DEPAOLO1 Appeal 2020-001915 Application 14/217,822 Technology Center 1600 Before DONALD E. ADAMS, ERIC B, GRIMES, and TAWEN CHANG, Administrative Patent Judges. GRIMES, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134(a) involving claims to a method of analyzing carcinogenesis of a tumor, which have been rejected for reciting new matter, indefiniteness, anticipation, and obviousness. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM IN PART. 1 Appellant identifies the real party in interest as Visible Genomics, LLC. Appeal Br. 1. We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appeal 2020-001915 Application 14/217,822 2 STATEMENT OF THE CASE Appellant’s Specification discloses “methods for revealing natural histories of cancers. In certain embodiments, the natural histories are revealed by systematically ‘walking through’ individual tumors, performing extensive sampling and analysis from normal cells external to the cancers, through the precursor lesions ‘peripheral’ to the cancers, and finally within the cancers.” Spec. 6:21 to 7:2. In embodiments of the present invention, upon resection, tumor and surrounding “normal-appearing” tissue may be flash frozen as a tissue block to preserve DNA and RNA. The tissue block may then be sectioned into multiple vertical samples. . . . Alternating sections may be stained with hematoxylin and eosin (H & E) as a guide for microdissection enabling use of observed cellular characteristics of the stained sections to guide selection of areas for dissection. Samples may be ascertained and collected by use of a laser capture microdissector. Id. at 11:20 to 12:4. Claims 1, 15–19, 21, 22, 24, and 25 are on appeal. Claims 1 and 25, reproduced below, are illustrative: 1. A method of analyzing carcinogenesis of a single, individual tumor by performing comparative whole genome sequencing on cell samples derived from a tissue block of a tissue sample, the method comprising: selecting a selected tissue block, the selected tissue block consisting of individual tumor tissue associated with a single, individual tumor, precursor lesion tissue surrounding the individual tumor tissue and associated with the single, individual tumor, and normal tissue surrounding the portion of precursor lesion tissue and associated with the single, individual tumor; removing the selected tissue block; Appeal 2020-001915 Application 14/217,822 3 flash freezing the selected tissue block; progressively sectioning the selected tissue block into a plurality of sections, the plurality of sections containing a series of sections containing the normal tissue, a series of sections containing the precursor lesion tissue, and a series of sections containing the individual tumor tissue associated with the single, individual tumor; staining alternating sections of the plurality of sections, creating alternating stained and unstained sections; characterizing the stained sections as containing one of normal tissue, precursor lesion tissue, and individual tumor tissue; collecting cell samples using laser capture microdissection from unstained sections, using the characterized, stained sections as a guide, wherein the collected cell samples include normal tissue cell samples, precursor lesion tissue cell samples, and individual tumor tissue cell samples; isolating DNA from the normal tissue cell samples; performing whole genome sequencing on DNA isolated from the normal tissue cell samples; establishing a genetic baseline derived from the normal tissue cell samples; isolating DNA from the precursor lesion tissue cell samples and the individual tumor tissue cell samples; performing whole genome sequencing on DNA isolated from the precursor lesion tissue cell samples and the individual tumor tissue cell samples; and comparing DNA sequence information of the precursor lesion tissue cell samples and the individual tumor tissue cell samples to the genetic baseline derived from the normal tissue cell samples; and identifying alterations in the DNA sequence information associated with carcinogenesis based on the comparison of Appeal 2020-001915 Application 14/217,822 4 DNA sequence information derived from the precursor lesion tissue cell samples and the individual tumor tissue cell samples as compared to the genetic baseline. 25. A method for analyzing carcinogenesis in a single, individual tumor comprising: isolating a tissue sample, the tissue sample having a tumor tissue, a precursor lesion tissue surrounding the tumor tissue and associated with the individual tumor, and a normal tissue surrounding the precursor lesion tissue and associated with the individual tumor; selecting and isolating a selected tissue block from the tissue sample, the selected tissue block comprising each of the normal tissue, the precursor lesion tissue, and the tumor tissue; progressively sectioning the tissue block to obtain a plurality of normal tissue sections, precursor lesion tissue sections, and tumor tissue sections; isolating DNA from cell samples taken from at least one section of normal tissue; establishing a genetic baseline derived from the isolated DNA of cell samples taken from the section of normal tissue; isolating DNA from cell samples taken from at least one section of precursor lesion tissue and at least one section of tumor tissue; and performing comparative large scale analysis on the isolated DNA of cell samples taken from each of the normal tissue, the precursor lesion tissue, and the individual tumor tissue, wherein the genetic baseline derived from the isolated DNA of cell samples taken from the section of normal tissue is used as a baseline in the comparative large scale analysis. Appeal 2020-001915 Application 14/217,822 5 The claims stand rejected as follows: Claim 21 under 35 U.S.C. § 112(a) for lack of adequate written description (Final Action2 4); Claims 1, 15, 16, and 25 under 35 U.S.C. § 112(b) as indefinite (Final Action 5); Claim 25 under 35 U.S.C. §§ 102(a)(1) and 102(a)(2) as anticipated by Czerniak3 (Final Action 7); Claims 1, 15, and 16 under 35 U.S.C. § 103 as obvious based on Czerniak, Gui,4 Tabor,5 Richards,6 and Doyle7 (Final Action 9); Claims 17–19 and 21 under 35 U.S.C. § 103 as obvious based on Czerniak, Gui, Tabor, Richards, Doyle, Guo,8 and Ukai9 (Final Action 14– 15); 2 Office Action mailed Jan. 31, 2019. 3 Czerniak et al., US 2003/0165895 A1, pub.

Appeal 2020-001915 Application 14/217,822 6 Claim 22 under 35 U.S.C. § 103 as obvious based on Czerniak, Gui, Doyle, Guo, and Ukai (Final Action 22); and Claim 24 under 35 U.S.C. § 103 as obvious based on Czerniak, Gui, and Doyle (Final Action 27). OPINION 35 U.S.C. §§ 112(a), 112(b) Claim 21 stands rejected under 35 U.S.C. § 112(a) on the basis that the Specification does not support “the alternative use of hematoxylin or eosin as a tissue stain,” and therefore the limitation of performing staining with “either hematoxylin or eosin,” as recited in claim 21, amounts to new matter. Final Action 4. Claims 1, 15, 16, and 25 under 35 U.S.C. § 112(b) on the basis that various limitations recited in these claims are indefinite. Final Action 5–6.10 Appellant acknowledges the rejections under § 112, but states that “[t]he present appeal is directed to . . . the rejections under 35 U.S.C. §§ 102 and 103.” Appeal Br. 2. Because Appellant has waived arguments directed to the rejections under 35 U.S.C. §§ 112(a) and 112(b), we affirm them. See 37 C.F.R. § 41.37(c)(1)(iv) (The Appeal Brief must contain “[t]he arguments of appellant with respect to each ground of rejection.”). See also Hyatt v. Dudas, 551 F.3d 1307, 1314 (Fed. Cir. 2008) (“When the appellant fails to contest a ground of rejection to the Board, . . . the PTO may affirm the 10 The Examiner does not point to any specific limitation of claim 15 as being indefinite, so we assume that it is included in this rejection because it depends from claim 1. Appeal 2020-001915 Application 14/217,822 7 rejection of the group of claims that the examiner rejected on that ground without considering the merits of those rejections.”). 35 U.S.C. §§ 102(a)(1), 102(a)(2) Claim 25 stands rejected as anticipated by Czerniak. The Examiner finds that Czerniak discloses all of the limitations of claim 25, including “isolating a tissue sample . . . (e.g. single cystectomy specimens comprising normal urothelium, precursor intraurothelial conditions and invasive carcinoma . . . ),” “selecting and isolating a selected tissue block from the tissue sample . . . (e.g. an entire bladder mucosa from a bladder cancer patient; e.g. paragraph [0344]; e.g. the bladder was opened longitudinally along the anterior wall and pinned down to a paraffin block . . . ),” and progressively sectioning the tissue block to obtain a plurality of normal tissue sections, precursor lesion tissue sections, and tumor tissue sections (e.g. separating the entire bladder mucosa into 30–60 1x2 cm samples; e.g. paragraphs [0036], [0344]; e.g. single histologic sections were prepared from each of the 1x2 cm tissue samples (i.e. larger sections); e.g. paragraph [0344], wherein slicing one section from a tissue sample produces two sections; see also Figures 27[ ]and 46AB illustrating that sections of normal, precursor and tumor tissue were present). Final Action 7. Appellant argues that Czerniak does not disclose all of the limitations of claim 25. Appeal Br. 12. Appellant argues that “Czerniak discloses ‘whole-organ histologic and genetic mapping.’ . . . The entire lining of the bladder is stripped for analysis and mapping.” Id. at 13. Appellant argues that there is no disclosure of deliberately selecting a selected tissue block that contains the normal, precursor, and tumor tissue Appeal 2020-001915 Application 14/217,822 8 associated with a single tumor. Moreover, there is no disclosure of such a selection to allow for progressive sampling along an uninterrupted continuum of adjacent tissue, through individualized tumor tissue samples, precursor tissue that surrounds this tumor tissue, and normal tissue that in turn surrounds the precursor tissue. Czerniak, accordingly, does not teach or suggest (a) selecting a selected tissue block consisting of tumor, precursor, and normal tissue associated with a single tumor, or (b) progressively sectioning such a tissue block, as recited by the pending claims. Id. at 14. More specifically, Appellant argues that the Examiner cites “Figure 27 as disclosing progressive sectioning along normal, precursor, and tumor tissue. . . . Figure 27 discloses samples derived from three cystectomies. The histologic maps of Czerniak are not based on progressive sampling along a continuum, nor is there any disclosure with reference with Figure 27 regarding such progressive sampling.” Appeal Br. 14. Thus, “[i]n light of the above, Appellant respectfully submits that Czerniak fails to disclose progressive sectioning along normal, precursor, and tumor tissue associated with an individual tumor.” Id. at 16. We agree with Appellant that the Examiner has not persuasively shown that Czerniak anticipates claim 25. “Anticipation requires that all of the claim elements and their limitations are shown in a single prior art reference.” In re Skvorecz, 580 F.3d 1262, 1266 (Fed. Cir. 2009). “[I]t is not enough that the prior art reference discloses part of the claimed invention, which an ordinary artisan might supplement to make the whole, or that it includes multiple, distinct teachings that the artisan might somehow combine to achieve the claimed invention.” Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008). “[U]nless a reference Appeal 2020-001915 Application 14/217,822 9 discloses within the four corners of the document not only all of the limitations claimed but also all of the limitations arranged or combined in the same way as recited in the claim, it cannot be said to prove prior invention of the thing claimed and, thus, cannot anticipate under 35 U.S.C. § 102.” Id. Czerniak discloses “a method of detecting the genetic changes in a subject related to the development and progression of cancers.” Czerniak ¶ 29. Czerniak states that its “methods . . . may be referred to as whole-organ histologic and genetic mapping.” Id. ¶ 36. Czerniak states that “[t]he simple anatomy and appropriate size of the bladder permit histologic and genetic mapping studies of invasive cancer and in situ preneoplastic conditions in the entire mucosa of cystectomy specimens.” Czerniak ¶ 36.11 The Examiner interprets Czerniak’s cystectomy specimen as the “tissue sample” that is isolated in the first step of claim 25. Final Action 7. Regarding the step of “selecting and isolating a selected tissue block from the tissue sample” that is recited as the second step of claim 25, the Examiner points to Czerniak’s disclosure that “[t]he bladder was opened longitudinally along the anterior wall and pinned down to a paraffin block.” Czerniak ¶ 344; see Ans. 7. The bladder that is opened and pinned down in Czerniak’s procedure, however, is the same tissue that the Examiner points to as the tissue sample from which a tissue block must be isolated according to claim 25. The plain meaning of “isolating a selected tissue block from [a] 11 “A cystectomy is a surgery to remove all or part of the bladder: A radical cystectomy removes the entire bladder. . . . A partial cystectomy removes part of the bladder.” UVA Health, www.uvahealth.com/services/urology/ cystectomy (last accessed March 4, 2021). Appeal 2020-001915 Application 14/217,822 10 tissue sample” requires removing part (a “tissue block”) of the tissue from the remainder of the tissue sample. Thus, manipulating the same sample (e.g., by opening a bladder and pinning it down) is not “isolating a selected tissue block from the tissue sample,” as required by claim 25. In addition, claim 25 requires “progressively sectioning the tissue block to obtain a plurality of normal tissue sections, precursor lesion tissue sections, and tumor tissue sections.” With regard to this limitation, the Examiner cites Czerniak’s disclosure that “the entire bladder mucosa was separated into individual 1x2-cm samples and evaluated under a microscope for histologic changes on frozen sections. For microscopic evaluation of urothelium, a single histologic sections [sic] was prepared from each 1x2 cm area.” Czerniak ¶ 344. See Final Action 7: progressively sectioning the tissue block to obtain a plurality of normal tissue sections, precursor lesion tissue sections, and tumor tissue sections (e.g. separating the entire bladder mucosa into 30–60 1x2 cm samples; e.g. paragraphs [0036], [0344]; e.g. single histologic sections were prepared from each of the 1x2 cm tissue samples (i.e. larger sections); e.g. paragraph [0344], wherein slicing one section from a tissue sample produces two sections; see also Figures 27[ ]and 46AB illustrating that sections of normal, precursor and tumor tissue were present); In our view, the Examiner’s interpretation of the claim language—as reading on the cited disclosure—is unreasonably broad, for two reasons. First, as discussed above, the tissue that Czerniak describes as being separated into 1 x 2 cm samples is the entire bladder mucosa. See Czerniak ¶ 344 (“[T]he entire bladder mucosa was separated into individual 1x2-cm samples.”). The entire bladder mucosa is the “tissue sample” recited in claim 25. The separation of that sample into 1 x 2 cm samples therefore does not Appeal 2020-001915 Application 14/217,822 11 meet the claim limitation requiring “progressively sectioning [a] tissue block” that was “isolat[ed] . . . from the tissue sample,” as required by claim 25. The Examiner also appears to interpret claim 25’s “progressive sectioning” as reading on Czerniak’s disclosure that “[f]or microscopic evaluation of urothelium, a single histologic sections [sic] was prepared from each 1x2 cm area.” Czerniak ¶ 344; see Final Action 7 (“slicing one section from a tissue sample produces two sections”). This interpretation is also unreasonably broad. The plain meaning of “progressively sectioning” of a tissue block requires more than cutting a single section from the tissue block; “progressively sectioning” requires dividing the tissue block into multiple, contiguous sections.12 Consistent with the plain meaning of the phrase, Appellant’s Specification states that “[t]he tissue block may then be sectioned into multiple vertical samples having approximately 5–10 μm thickness.” Spec. 11:21–23. See also id. at 6:22 to 7:3 (“[M]ethods for revealing natural histories of cancers . . . by systematically ‘walking through’ individual tumors, performing extensive sampling and analysis. . . . Embodiments of the present invention provide for progressive sampling of tissues and analysis of data obtained from such progressive sampling.”). In summary, the evidence does not support the Examiner’s findings that Czerniak discloses a method that includes “selecting and isolating a selected tissue block from the tissue sample [i.e., cystectomy specimen]” and 12 “progressively: gradually and steadily.” www.macmillandictionary.com/us/ dictionary/american/progressively (last accessed March 4, 2021). Appeal 2020-001915 Application 14/217,822 12 then “progressively sectioning the tissue block to obtain a plurality of normal tissue sections, precursor lesion tissue sections, and tumor tissue sections,” as required by claim 25. The Examiner therefore has not shown that Czerniak “discloses within the four corners of the document not only all of the limitations claimed but also all of the limitations arranged or combined in the same way as recited in the claim.” Net MoneyIN, 545 F.3d at 1371. We reverse the rejection of claim 25 under 35 U.S.C. §§ 102(a)(1) and 102(a)(2) based on Czerniak. 35 U.S.C. § 103 Claims 1, 15–19, 21, 22, and 24 stand rejected under 35 U.S.C. § 103 as follows: Claims 1, 15, and 16 based on Czerniak, Gui, Tabor, Richards, and Doyle (Final Action 9); claims 17–19 and 21 based on Czerniak, Gui, Tabor, Richards, Doyle, Guo, and Ukai (id. at 14–15); claim 22 based on Czerniak, Gui, Doyle, Guo, and Ukai (id. at 22); and claim 24 based on Czerniak, Gui, and Doyle (id. at 27). Independent claim 1, like claim 25, requires “selecting a selected tissue block,” where the tissue block is a “tissue block of a tissue sample” (as recited in the preamble), “removing the selected tissue block,” and “progressively sectioning the selected tissue block into a plurality of sections, the plurality of sections containing a series of sections.” See claim 1. Thus, claim 1 includes the same limitations that were discussed above with regard to claim 25. Independent claim 17 similarly recites “selecting and collecting . . . [a] tissue block” consisting of a “portion” of a tumor and a “portion” of Appeal 2020-001915 Application 14/217,822 13 surrounding tissue from a “tissue” that includes a tumor and surrounding tissue. Claim 17 also recites “progressively sectioning the tissue block into a plurality of sections.” See Appeal Br. 26 (Claims Appendix). Independent claim 22 similarly recites “selecting a selected tissue block” and “removing the selected tissue block.” Claim 22 also recites “progressively sectioning regions of the selected tissue block into a plurality of sections.” See Appeal Br. 27–28 (Claims Appendix). Independent claim 24 recites “isolating a tissue sample,” then “selecting and isolating a selected tissue block from the tissue sample.” Claim 24 also recites “progressively sectioning the tissue block to obtain a plurality of tissue sections.” See Appeal Br. 29 (Claims Appendix). As with the rejection for anticipation, the Examiner interprets “selecting and removing a tissue block” (with respect to claim 1), “selecting and collecting . . . [a] tissue block” (with respect to claim 17), “selecting and removing a selected tissue block” (with respect to claim 22), and “selecting and isolating a selected tissue block” (with respect to claim 24) to read on Czerniak’s disclosure that “the bladder was opened longitudinally along the anterior wall and pinned down to a paraffin block.” Final Action 10, 15, 22, 28. In addition, the Examiner interprets the step—recited in each of claims 1, 17, 22, and 24—of “progressively sectioning” a tissue block to read on Czerniak’s disclosure that “single histologic sections were prepared from each 1 x 2 cm tissue sample . . . wherein slicing one section from a tissue sample produces two sections.” Final Action 10, 15, 22, 28. Appeal 2020-001915 Application 14/217,822 14 Thus, each of the rejections under 35 U.S.C. § 103 relies on the same claim interpretation and the same disclosures in Czerniak that are discussed above with regard to the rejection for anticipation. For the same reasons discussed previously, we conclude that the Examiner’s interpretation of the above-quoted limitations is unreasonably broad, and the cited passages in Czerniak do not meet the claim limitations. The Examiner has not pointed to any disclosure in Gui, Tabor, Richards, Doyle, Guo, or Ukai that would make up for the deficiencies in Czerniak. See Final Action 12–14, 17–19, 24–25, 30. We therefore reverse all of the rejections under 35 U.S.C. § 103. CONCLUSION The rejections under 35 U.S.C. §§ 112(a) and 112(b) are affirmed. The rejection under 35 U.S.C. §§ 102(a)(1) and 102(a)(2), and all of the rejections under 35 U.S.C. § 103, are reversed.
