“For these reasons, we do not find persuasive the testimony of Patent Owner’s expert, Dr. Dobs, that: By describing adjustments of dosing protocols to achieve at least a 10% reduction from baseline, and describing this use of tildacerfont as just one embodiment of the claimed use of the entire well-known, well-characterized, and discrete class, the specification reasonably conveyed to a POSA that the invention extended to the particularly claimed use of the entire recited class. Ex. 2014 ¶ 87. On the contrary, far from being a “well-known, well-characterized, and discrete class” the prior art teaches a heterogeneous assembly of different classes of small molecule CRF1 receptor antagonists (Type I, Type II, and “atypical”) displaying a very considerable variety of structures, both in terms of the core pharmacophore (e.g., monocyclic, bicyclic, tricyclic, phenolic, cyclohexyl amide, etc.) as well as in the various side groups. Moreover, the challenged claims recite only “a CRF1 receptor antagonist or a pharmaceutically acceptable salt thereof,” the scope of which also encompasses the much larger (and, according to Williams) much more effective large-molecule (peptide) CRF1 receptor antagonists, about which the Specification is entirely silent.

“We agree with Jeisys. Mehta is not substantially the same as Mehta ’705. What Mehta ’705 omits, but Mehta includes, is an embodiment comprising “graphical user interface 320” and “tissue characteristic indicator 350” that allows a user to monitor the needle’s “location” in the tissue so as to decide when the needle is placed at a “desired depth.” Ex. 1006, 32:46– 13 US 8,540,705 B2, issued Sep. 24, 2013 (Ex. 1011). 14 Advanced Bionics, LLC v.

At best, Mehta ’705 discloses a “display screen” for displaying a “variety of information to the physician . . . such as treatment delivery settings, electrode impedance, electrode temperature, tissue temperature, treatment duration, power delivered, energy delivered, etc.” Ex. 1011 (Mehta ’705), 29:44–58, Figs. 10A, 10B. But, notably lacking from Mehta ’705 is any disclosure of determining the “depth” and “location” of the needle’s placement in the tissue, let alone means for doing so, which Mehta discusses at length and upon which Jeisys relies to meet the “desired distance” limitation. See Ex. 1006, 32:46–33:61; Pet. 27–28. Because Mehta includes disclosure relevant to the disputed “desired distance” limitation that is absent from Mehta ’705, Serendia fails to satisfy the first part of the Advanced Bionics framework.

- Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Instituted
“We disagree with Serendia’s analysis of Mehta. As Jeisys correctly explains, Mehta discloses the “desired distance” limitation even assuming Serendia’s construction of that limitation, i.e., that the needles are extendable to a depth selected by the user. See Pet. 33. Indeed, although Mehta may not use the term “desired distance” expressly, it comes about as close as one would expect from an anticipatory disclosure. For example, as Jeisys notes, Mehta discloses an embodiment that includes “depth markings” on the needles (i.e., probes) that allow the user to determine a desired depth of the needles— The electrodes of the probe array can also include any number of visually distinguishing features (e.g., depth markings, colors, shades, etc.) that enable a physician to observe proper placement. . . . This ensures that the probe is not driven too far into tissue. Alternatively, the probe can be marked with one or more features that allow the physician to determine the depth of insertion of the probe. Id. (citing Ex. 1004, 13:37–45 (emphases added)). Notably, as Jeisys also explains, Mehta discloses another embodiment, depicted in Figures 10A–F, having a graphical user interface 320 (“GUI”) that displays the actual and target depths of needles so as to avoid placement of the needles in an undesired region. See id. at 32–34 (citing Ex. 1004, 10:38–39, 12:5–8, 32:63–33:43; Ex. 1003 ¶¶ 101–104). The GUI, as described, “can provide information for a physician (or other medical staff) to monitor various treatment parameters as well as other information regarding the placement of the array 108 or probes 104 when inserted in the tissue” and “maintain visual contact with the treatment device and tissue being treated.” Ex. 1004, 11:1–13. To do so, the GUI incorporates a “tissue characteristic indicator (whether visual, virtual, audible, or other feedback)” that allows the user to monitor the needle’s actual location in the tissue and advance the needle a desired distance for providing treatment— FIG. 10B illustrates a tissue characteristic indicator showing a virtual depiction 350 of the depth or location of the probe array. . . . [T]he virtual depth/location depiction 350 can illustrate an actual placement of the probe array 340. . . . [T]he system can be configured to show (or the system can have an option to show) additional probe array information. For example, the virtual depth/location depiction 350 can also show a desired probe location (e.g., array 342 can represent the desired depth of placement for providing a treatment). . . . As shown by FIG. 10B, providing the virtual depth/location depiction 350 allows the physician to not only identify whether the array is located within the desired tissue layer but also allows the physician to observe the angle of the electrode array in tissue. . . . Therefore, the physician would be informed that further advancement of the probes is necessary to place the probes within the second layer 326 (which corresponds to the dermal layer).

For instance, in Ford, the Director explained that “[u]nder existing Office policy and precedent, the Board does not recognize a ‘significant relationship’ between parties [i.e., serial petitioners] having different accused products that merely engage in court-ordered pretrial coordination.” Ford, at 9 (emphasis added). And, in Videndum, the Director further explained that where “the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors.” See Videndum, Paper 12, 6–7. Thus, per Ford and Videndum, we will not discretionarily deny a later petition in view of an earlier petition where the earlier and later petitioners are neither the same party nor have a significant relationship. After reviewing the record, we find that no significant relationship exists with Cartessa to justify application of the General Plastic/Valve framework. Contrary to Serendia’s assertions about the joint invalidity defense of Jeisys and Cartessa in the parallel ITC proceeding (see Prelim. Resp. 9–10), the relevant facts and circumstances here are akin to those in Ford. More specifically, like the “court-ordered” coordination of the petitioners in Ford, the collaboration of Jeisys and Cartessa as co-respondents in the ITC proceeding was mandated by the rules of the ITC proceeding, and, thus, does not alone create the type of “significant relationship” contemplated by Valve. See Pet. Reply 2–3 (citing Ford, at 3; Exs. 1028, 1029); see also Prime Time Toys LLC v. Spin Master, Inc., IPR 2023-01339, Paper 12, at 19–20 (Vidal July 9, 2024) (“Prime Time Toys”) (“The parties’ collaboration as co-respondents in the ITC investigation does not by itself support a finding of a “significant relationship.”). As such, Jeisys’s knowledge of the prior art asserted in the ITC proceeding and its collaboration with Cartessa on a joint invalidity defense does not create a significant relationship where such knowledge and collaboration arises from the rules of the ITC proceeding itself.” slip op. at 8

“We need not formally construe the “desired distance” limitation in order to resolve whether institution is appropriate. That is because, on the current record, the asserted prior art satisfies the “desired distance” limitation regardless of which parties’ proposed construction we adopt. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). Nonetheless, the parties are free to further explore the appropriate construction of “desired distance” at trial, in particular, whether the language of the claims limits the scope of claims 13 and 14 to “extendable” needles, and whether construing the “desired distance” limitation as being based on a user’s selection improperly reads a preferred embodiment into the claims.” slip op. at 12

“We disagree with Serendia’s analysis of Mehta. As Jeisys correctly explains, Mehta discloses the “desired distance” limitation even assuming Serendia’s construction of that limitation, i.e., that the needles are extendable to a depth selected by the user. See Pet. 26–27. Indeed, although Mehta may not use the term “desired distance” expressly, it comes about as close as one would expect from an anticipatory disclosure. For example, as Jeisys notes, Mehta discloses an embodiment that includes “depth markings” on the needles (i.e., probes) that allow the user to determine a desired depth of the needles— The electrodes of the probe array can also include any number of visually distinguishing features (e.g., depth markings, colors, shades, etc.) that enable a physician to observe proper placement. . . . This ensures that the probe is not driven too far into tissue. Alternatively, the probe can be marked with one or more features that allow the physician to determine the depth of insertion of the probe.” slip op. at 14

“First, the Federal Circuit “has not hesitated to hold preambles limiting when they state an intended purpose for methods of using a compound.” Eli Lilly & Co. v. Teva Pharms. Int’l GmbH, 8 F.4th 1331, 1342 (Fed. Cir. 2021). And where, as here, the claims are directed to methods of using a compound for a specific purpose (i.e., treating a macular degeneration), and the method comprises a single step of administering that compound in an 30 effective amount, the Federal Circuit “[has] generally construed statements of intended purpose in such method claims as limiting.” Id. at 1340. Moreover, “[w]hen limitations in the body of the claim rely upon and derive antecedent basis from the preamble, then the preamble may act as a necessary component of the claimed invention.” Eaton Corp. v. Rockwell Int’l Corp., 323 F.3d 1332, 1339 (Fed. Cir. 2003); see also Eli Lilly & Co., 8 F.4th at 1341. In this case, claim 28 recites “[a] method of treating a macular degeneration, comprising administering an effective amount of a substituted C20-D1-3-retionoid to a patient in need thereof.” The preamble of “treating a macular degeneration” is necessary to understand the patients to whom the substituted C20-D1-3-retionoid should be administered; thus, it limits the claim. See Eli Lilly & Co., 8 F.4th at 1341–42 (citing Jansen v. Rexall Sundown, Inc., 342 F.3d 1329, 1332–33 (Fed. Cir. 2003)); Rapoport v. Dement, 254 F.3d 1053, 1059 (Fed. Cir. 2001) (holding the preamble to be limiting in a claim directed to “[a] method for treatment of sleep apneas comprising administration of a therapeutically effective amount of a [recited] compound . . . to a patient in need of such treatment,” because otherwise “the phrase ‘to a patient in need of such treatment’ would not have a proper antecedent basis”). Thus, we construe the preamble of claim 28 as limiting and give patentable weight to the phrase “method of treating a macular degeneration.” To the extent either party disagrees with our construction, the parties are welcome to further address this issue at trial.” slip op. at 30

“The Petition points to Mata’s express suggestion of “‘[p]harmacologic inhibition of one or more steps in the A2E synthetic pathway’ as ‘an effective treatment strategy for other macular degenerations associated with lipofuscin accumulation.’” Pet. 31 (quoting Ex. 1010, 7159) (alteration in original). The Petition, again relying on Dr. Guengerich’s testimony, further explains Mata taught that deprotonation at C-20 of retinal — involving cleavage of a carbon-hydrogen bond — was “a pre-requisite for undesirable A2E formation,” and that a skilled artisan “would have recognized that this deprotonation likely was a rate-limiting step in A2E formation” such that slowing the deprotonation “would slow A2E formation,” i.e., lower the production of a toxic reaction product. Id. at 41 (citing Ex. 1002 ¶¶ 259– 260). Moreover, although the evidence of record may suggest that, at least as of 1999, “there are no drugs on the market that contain deuterium in the molecule,” Ex. 1046, 85, left col., Petitioner has also provided evidence, for instance in the form of Dr. Calman’s testimony, that “there was significant interest in making deuterated versions of known therapeutics in order to slow rates of undesirable reactions.” Ex. 1004 ¶ 96; see also Pet. 15 (stating that “it was known before 2007 to . . . use deuterium to slow undesirable reaction”) (citing Ex. 1002 ¶ 123; Ex. 1004 ¶¶ 96–102). 18 Kushner et al., Pharmacological Uses and Perspectives of Heavy Water and Deuterated Compounds, 77 CANADIAN J. PHYSIOLOGY & PHARMACOLOGY 79 (1999) (Ex. 1046, “Kushner”). 37 Finally, we note that claim 1, at least, is not directed to a method of treating any particular disease, but only a method of retarding the accumulation of particular compounds (i.e., lipofuscin pigments). We are persuaded, at least at this stage of the proceeding and based on the present record, that Petitioner has shown sufficiently that a skilled artisan would have had a reason to use C20-deuterated vitamin-A in the manner suggested in the Petition, with a reasonable expectation of success, based on alleged similarities between the use of deuterated compounds in the claimed method and use of such compounds to, e.g., lower production of toxic metabolites.” slip op. at 37

“Although Patent Owner’s definition of a POSA includes an additional four to six years of experience, we do not discern a substantive difference between the parties’ respective definitions for purposes of our analysis. Both definitions provide for a highly skilled POSA with experience in formulating drugs, and our Decision would be unchanged whether we applied Petitioner’s definition or Patent Owner’s. Nevertheless, on this record, we adopt Patent Owner’s definition as it is consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Because Petitioner’s construction—with Patent Owner’s addition—is consistent with the Specification, we apply that construction of “enteric capsule” in this proceeding. See Ex. 1001, 39:22–26. We also note that Patent Owner appears to construe the claim phrase “the compound of Formula (III) is (Z)-endoxifen” to be limited to the free base form of (Z)-endoxifen. See, e.g., Prelim. Resp. 2 (“The ’334 patent claims enteric coated capsule formulations containing at least 90% (Z)- endoxifen free base, methods of delivering such formulations to a patient resulting in specific pharmacokinetic parameters, and methods of treating hormone-dependent breast and reproductive tract disorders.”) (emphasis added). The Specification, however, expressly states “‘a compound’, such as compounds of . . .

“Level of Ordinary Skill in the Art In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995). Furthermore, the prior art itself can reflect the appropriate level of ordinary skill in the art. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Here, Petitioner asserts that an ordinarily skilled artisan “would typically have an advanced degree, such as a Ph.D., with research experience in genomics, molecular biology, bioinformatics, or a related field, or could have less education but significant professional experience in one or more of these fields.” Pet. 8–9 (citing Ex. 1002 ¶ 38).

“1. “Sequence Reads” Petitioner argues that, for purposes of this Decision, no claim term needs specific construction beyond its plain and ordinary meaning. Pet. 10–11. Petitioner, however, seeks to provide context for understanding the scope of the term “sequence reads.” Specifically, Petitioner contends that “sequence reads” are produced by sequencing at least some of the tagged strands, whereas “consensus sequences” are generated by collapsing sequence reads.

“We disagree with Patent Owner’s proposed construction of the terms “paired sequence reads” and “unpaired sequence reads.” Even though the ’951 patent Specification discloses grouping sequence reads “sharing a unique set of SMI tags” into paired families,4 “[t]he written description part of the specification itself does not delimit the right to exclude. That is the function and purpose of claims.” Phillips, 415 F.3d at 1312 (“[T]he claims of a patent define the invention to which the patentee is entitled the right to exclude.”). Here, claim 1 explicitly defines the terms “paired sequence reads” and “unpaired sequence reads.” Indeed, in the context of paired versus unpaired sequence reads, claim 1 specifies that the complementarity is related to the “original parent polynucleotide molecule,” and not the duplex tags. For example, claim 1 recites that “each unpaired read represents a first tagged strand having no second differently tagged complementary strand derived from an original parent polynucleotide molecule represented among said sequence reads in said set of sequence reads.” Ex. 1001, 37:50–55 (emphasis added).

“Claim 1 defines the terms “paired sequence reads” and “unpaired sequence reads” based on the complementarity of the target sequence strands derived from the “original parent polynucleotide molecule.” Ex. 1001, 37:46–55. As explained above, we reject Patent Owner’s contention that a sequence read is considered unpaired solely based on the complementarity of the SMI tags. See supra Section II.C.2. Due to the “errors introduced during sample preparation and sequencing” (Ex. 1029 ¶ 5), there are four outcomes when determining the complementarity of the sequence reads of two strands of SMI-linked target sequence: (1) the first SMI tag and the first strand target sequence are complementary to the second SMI tag and the second strand target sequence, respectively; (2) the first SMI tag is complementary to the second SMI tag but the first strand target sequence is not complementary to the second strand target sequence; (3) the first SMI tag is not complementary to the second SMI tag but the first strand target sequence is complementary to the second strand target sequence; and (4) the first SMI tag is not complementary to the second SMI tag, and the first strand target sequence is not complementary to the second strand target sequence. It is undisputed that Schmitt groups sequence reads into paired families based on the SMI tags, and Schmitt only considers sequences in which “information from both DNA strands was in perfect agreement.” Ex. 1029 ¶¶ 14, 96; PO Resp. 18. Thus, among the four outcomes, only scenario (1), in which both the SMI tags and the target sequences are complementary, represents a “paired sequence read,” which claim 1 defines as corresponding to “sequence reads generated from a first tagged strand and a second differently tagged complementary strand derived from an original parent polynucleotide molecule.” Ex. 1001, 37:46–50.
