  • Strike new argumentNew argument consideredDenied

    “III. MOTIONS Motion to Strike (Paper 50) Petitioner filed a motion to strike portions of Patent Owner’s Sur- Reply. Paper 50. Patent Owner opposes the motion. Paper 53. Petitioner contends Patent Owner raised new argument about Exhibit 1014 (a paper authored by Dr. Patterson), which was submitted with the filing of the Petition but only cited by Patent Owner for the first time in its Sur-Reply. Paper 50, 1–3; PO Sur-Reply 14 (citing Ex. 1014). According to Petitioner, Patent Owner presents new argument about the reversibility of certain crosslinks caused by formaldehyde, cites new experimental data (in Ex. 1014, Fig. 2.1), and argues such matters would have been known before any possible priority date of the ’277 patent. Paper 50, 1–3. Moreover, Petitioner argues, the untimeliness of Patent Owner’s arguments about Exhibit 1014 prevented the exhibit’s author, Dr. Patterson, from addressing them to provide explanation or context. Id. at 2–3. For the reasons given below, we deny Petitioner’s motion to strike. First, we find that Patent Owner’s arguments on Exhibit 1014 are, on balance, responsive to issues raised by Petitioner in its Reply. It is true that Petitioner submitted Exhibit 1014 with its Petition and that Patent Owner did not cite it until its Sur-Reply. However, the points raised by Patent Owner about Exhibit 1014 respond to certain of Petitioner’s arguments raised for the first time in its Reply. For example, Petitioner argued a POSA would not have been concerned about formaldehyde’s use (such as cross-linking disclosed in Heinmoller that Patent Owner cited in its Response) and that those concerns arose only after the supposed priority date of the ’277 patent. 88 Pet. Reply 8–9. Patent Owner’s citation of Exhibit 1014 is responsive on such points (e.g., it discusses cross-linking with formaldehyde’s use), it published in 2000 and is thus earlier than some references Petitioner argued were too late to evidence a POSA’s knowledge, and, lastly, it was authored by Dr. Patterson and arguably called into question the credibility of rebuttal opinions he offered about the state of a POSA’s knowledge on such issues. Second, Exhibit 1014 does not, ultimately, help Patent Owner as we do not rely on the portions of Exhibit 1014 cited by Patent Owner or Patent Owner’s argument about them. As discussed in our analysis, if cross-linking (as reported in Heinmoller or, for that matter, Exhibit 1014) was a perceived problem, Dr. Patterson provides a credible explanation how it could be and likely was addressed by Pertl.54 Supra Section II(G)(3) (citing Ex. 1047).” slip op. at 88

    “Claim 39 describes a device used to treat a subject by creating an electromagnetic field to “tune” the brain and affect mood, focus, and cognition of human subjects. Ex. 1001, 62:62–63:34. Briefly, claim 39 recites a device that creates an electromagnetic field using an electromagnet. A first processor “tunes” the brain by firing the magnetic field. The first or a second processor moves one of the recited frequency characteristics in the brain to a preselected different frequency. The term “moves” in claim 39 describes a function of the first or second processor, which provides the means by which the brain frequency is shifted. See MasterMine Software, Inc. v. Microsoft Corp., 874 F.3d 1307, 1312–1315 (reviewing cases applying and distinguishing reasoning in IPXL Holdings, 430 F.3d at 1383– 84. Unlike IPXL Holdings, there is no confusion here as to when infringement of this claim would occur; infringement occurs when one makes, uses, offers to sell, or sells the claimed apparatus, which is capable of use for treatment. For this reason, we find that the recitation “wherein the first processor or a second processor moves” in claim 39 does not recite a method step, but rather describes the function of the recited structure – the first or second processor – that is capable of performing the recited (a) through (e) steps. MasterMine, 874 F.3d at 1315–16 (“the claims at issue here merely claim that the system ‘possess[es] the recited structure [which is] capable of performing the recited functions.’”) (alterations in original). As a result, we agree with Patent Owner that the recitation “wherein the first processor or a second processor moves” is limiting.7 For purposes of resolving whether to institute trial, we adopt and apply the interpretations stated in the district court’s claim construction order, Ex. 2001.” slip op. at 11

    “(1) Alleged express disclosure The evidence of record does not support that Klimesch expressly discloses the intrinsic frequency limitation. Although Klimsech discloses treating subjects with rTMS at a frequency one Hz above the intrinsic frequency (IAF + 1 HZ), it does not disclose whether the treatment moves the intrinsic frequency. See generally, Ex. 1005. Petitioner asserts that stimulation at IAF + 1 Hz “triggered increased EEG output in the EEG band of that stimulation frequency (IAF to IAF + 2 Hz) directly corresponding to enhanced alpha power in that EEG band.” Pet. 27. Enhancing EEG power is, however, distinct from moving frequency. See, e.g., Ex. 2002, Fig. 1A (spectral analysis plotting frequency on the x-axis and power on the y-axis). Thus, even if we were to credit Petitioner’s assertion that stimulation at IAF + 1 Hz “increased EEG output” and “enhanced alpha power,” such assertion does not support that Klimesch expressly discloses moving the frequency at which peak alpha power is observed. Petitioner also directs us to Klimesch’s disclosure that rTMS at IAF + 1 Hz resulted in “a significant increase in lower-2 and upper alpha desynchronization (ERD) during mental rotation.” Ex. 1005, 1132 (cited at Pet. 27–28). But ERD is also distinct from frequency. See, e.g., Ex. 2002, Fig. 1A (spectral analysis showing ERD as the difference in alpha power when subjects are performing a task as compared to when subjects are in a state of alert wakefulness). Thus, an increase in ERD does not support that Klimesch discloses changing the frequency at which peak alpha power is observed. As Petitioner does not direct us to any other disclosure in Klimesch that supports moving the intrinsic frequency, Petitioner is unlikely to prevail in establishing that Klimesch expressly discloses the intrinsic frequency limitation.12” slip op. at 18

In summary, given that it not accompanied by supporting evidence, does not provide any technical reasoning, and is not specific to Klimesch, we give little weight to Dr. Silvetz’s testimony in determining whether Petitioner has established a reasonable likelihood that Klimesch inherently discloses the intrinsic frequency limitation. We do not determine here that Dr. Silvetz’s testimony is incorrect, only that it is insufficiently supported by evidence and technical reasoning to be accorded substantial weight.” slip op. at 18

    “presents is whether a claimed agent that inhibits cell lysis may be a chelator used as an anticoagulant. The Specification and prosecution history make clear that at least one anticoagulant chelator—EDTA—is excluded from satisfying the claimed agent as recited in claim 1. As discussed above, the Specification describes an example where a sample processed in a tube with only EDTA is described as processing a sample in the “absence” of an agent that inhibits cell lysis. Ex. 1001, 89:35–57 (describing, in contrast, the EDTA + formalin sample as showing an example in the “presence of inhibitors of cell lysis”). If EDTA alone could be read as meeting the “agent” limitation, that example would make no sense. Petitioner provides no persuasive argument otherwise. The prosecution history buttresses the exclusion of the anticoagulant chelator EDTA from being the claimed “agent.” For example, during prosecution of the related ’277 patent, the Examiner at one point expressly 20 identified the EDTA in the tubes of a prior art reference as satisfying the agent term, prompting applicant’s argument that the Office was “incorrect” in doing so, and further distinguishing EDTA as merely “a well-known chelator of calcium and magnesium” that is added to blood “as an anticoagulant due to its ability to chelate calcium.” Ex. 2064, 1196 (arguing “EDTA is clearly referred to as a chelator in Applicant’s specification, not as a cell lysis inhibitor”); supra Section I(E); Ex. 1001, 32:61–64 (listing EDTA and EGTA as chelators). This, in turn, convinced the Examiner to withdraw the finding that EDTA was an “agent” as claimed and move on to art that disclosed formaldehyde as meeting that claim term. Ex. 2064, 1024 (Examiner interview summary noting that “applicant pointed out [that] EDTA could not be defined as a cell lysis inhibitor but rather was simply an anticoagulant”). This colloquy during prosecution evidences a clear and unmistakable disavowal of EDTA as being the claimed “agent.” Having determined that Patent Owner disavowed EDTA as the claimed “agent,” we next consider whether the disavowal extends more broadly to other anticoagulant chelators and, specifically, to ACD. On this record, we find that it does as explained below. In distinguishing EDTA from being the “agent,” Patent Owner relied not on properties that are unique to EDTA, but on the fact that it was a “well-known chelator” used as an anticoagulant in this technical field. Ex. 2064, 1196. Given Patent Owner’s clear intent to exclude EDTA from the scope of the claimed “agent” on the basis that it was simply an anticoagulant chelator, we find that a POSA would also have understood other anticoagulant chelators as subject to Patent Owner’s disavowal.” slip op. at 20

    “Dr. Van Ness’s proposed POSA level is too broad. Under that proposal, an individual with, for example, an undergraduate degree in microbiology and three years’ work experience studying the habitats of bacteria might qualify as a POSA. It is not clear that such a person would have sufficient, relevant experience in the detection of chromosomal abnormalities, especially through non-invasive methods for detecting fetal 10 genetic abnormalities in maternal samples, as described in the ’720 patent. See, e.g., Ex. 1001, 1:22–5:44 (Field of Invention and Background Art). Petitioner’s proposal of the POSA level is more precise because it requires familiarity with techniques for detecting cell-free DNA in biological samples, which is relevant to the prior art and the claimed technology.

    “Owner relied not on properties unique to EDTA, but on the fact that it was a “well-known chelator” and anticoagulant: [T]he assertion by the Office that EDTA is a cell lysis inhibitor is simply incorrect. . . EDTA is not an “agent that inhibits cell lysis.” Rather, EDTA is a well-known chelator of calcium and magnesium. EDTA is routinely added to blood during the blood collection process as an anticoagulant due to its ability to chelate calcium. Ex. 2064, 1196. Given Patent Owner’s clear intent to exclude EDTA from the scope of the claimed “agent” on the basis that it was a chelator and an anticoagulant, we find that a POSA would have understood other chelators and anticoagulants to also be excluded from the scope of the claimed agent. Consistent with this understanding, during subsequent prosecution of the application that issued as the ’720 patent, Patent Owner argued that the Holodniy reference, which disclosed a method of detecting free nucleic acid in which blood was collected in tubes containing ACD, “fail[ed] to teach or suggest a method for detecting free nucleic acid comprising, inter alia, isolating free nucleic acid from a non-cellular fraction of a sample, wherein an agent that impedes cell lysis has been added.” Ex. 1003, 1428 (emphasis added). On the salient point here, the Examiner agreed, concluding that “Holodniy et al. teach a method of detecting free nucleic acid which comprises all of the limitations of Claim 1, except these authors do not teach that their samples comprise an agent that impedes cell lysis.” Id. at 1344 (emphasis added); see also id. at 1156 (finding that Adams et al., a reference that also collects blood in tubes containing ACD, taught “all of the limitations recited in Claim 1 except these authors do not teach adding an agent that impedes cell lysis to the sample.”). And Patent Owner argues 15 persuasively, without dispute from Petitioner, that ACD is the “only” addition to the collection tubes besides the blood sample itself. Sur-reply 4 (citing Ex. 1016, 2; Ex. 2023, 20:52–54).

    “function to prevent cell lysis, “by: (1) interacting with and stabilizing the cell membrane; (2) maintaining osmolarity so that the cells do not rupture; and (3) providing a nutrient source.” Reply 3 (citing Ex. 1002 ¶¶ 22–23; 2001 ¶ 169; Ex. 1059 ¶ 5; Ex. 1054, 125:3–127:12; 1057, 3–4, and Ex. 1056, 7– 13, 15–19, 24).

While this evidence could have been included in the Petition, it is responsive to arguments raised in Patent Owner’s response. See PO Resp. 18–22. In any event, consideration of this evidence simply explains how and why dextrose has the capacity to impede cell lysis, and we have already found that the ’720 patent provides 25 evidence that dextrose has this capacity. Under the circumstances, it was therefore reasonable for Petitioner, in the Petition, to rely on such disclosures of the patent itself. Further, consideration of how and why dextrose impedes cell lysis largely benefits Patent Owner, by providing reasons why dextrose might not inhibit cell lysis under the specific circumstance present in Lee.” slip op. at 25

    “interact with and stabilize the cell membrane. Reply 3 (citing Ex. 1002 ¶¶ 22–23). In the cited testimony, Dr. Edwards states, “it was known that carbohydrates have a role in membrane stabilization” and that dextrose “is a membrane stabilizer.” Ex. 1002 ¶¶ 22–23. This is consistent with the teaching in the ’720 patent that glucose is “[a]n agent that stabilizes cell membranes.” See e.g., Ex. 1001, 6:49–56. The evidence thus supports that dextrose can help to stabilize cell membranes. However, this evidence is tempered by evidence supporting that the “impact of carbohydrates on biological membranes is extremely complex” and that it is “extremely difficult to predict how solutes such as carbohydrates will affect biological membranes.” Ex. 2231, 60:18–61:2, 83:14–18 (Dr. Edwards testimony). This is because “there’s a finite but long – long list of variables that will impact the – the mechanism by which carbohydrate interacts with the cell membrane.” Id. at 66:20–67:7; see also id. at 66:1–15 (identifying temperature, concentration and pressure as variables that play a role in how carbohydrates interact with biological membranes); id. at 68:1–17 (identifying prior and simultaneous exposure to other substances as variables that play a role in how carbohydrates interact with biological membranes). 26 Petitioner also provides evidence that dextrose helps prevent cell lysis by “maintaining osmolarity so that cells do not rupture.” Reply 3 (citing Ex. 2001 ¶ 169; Ex. 1056, 7–13, 24; Ex. 1059 ¶ 5). We agree that the cited evidence supports that dextrose has the ability to prevent cell rupture by maintaining isotonicity. In particular, Rapoport found that erythrocytes in an acid-citrate glucose solution underwent osmotic hemolysis at a slower rate than erythrocytes in a simple citrate solution. Ex. 1056, 613. However, Patent Owner introduces evidence, which we credit, that the failure to maintain isotonicity does not necessarily cause cell lysis. Ex. 2299, 237:4– 16 (Dr. Edward’s testimony). For example, cells placed in a hypertonic solution may “shrink or kind of shrivel” rather than burst, and cells placed in a hypotonic solution may swell, but will not necessarily lyse.

    “We are sympathetic to Patent Owner’s argument that a POSA would have had at least some experience with the optical systems used in optical analyzers. All of the claims recite an “optical analyzer” and the Specification is replete with references to optical analyzers and their operation. See, e.g., Ex. 1001, Abstr., 1:14–15, 2:3–4, 2:18–29, 3:38–57, 9:55–10:59 (claims reciting an “optical analyzer”). Moreover, Patent Owner cites other evidence that also suggests a POSA would have such experience. See Prelim. Resp. 12–13. However, on the current record, we are not convinced that the ordinary level of skill in the art would necessarily require the amount of specific experience (i.e., two years working and/or designing optical systems in optical analyzers) that Patent Owner urges. Petitioner’s declarant, Dr. Fang, testifies that two years of experience “in the field of optical imaging, with a specific focus on laser optics” would suffice. See Ex. 1002 ¶ 9. Thus, while it seems likely that a POSA would have at least some experience specific to optical analyzers, we see no reason why additional experience with laser optics more generally could not provide the balance of the two years of experience noted in the parties’ definitions. In any event, we need not resolve this issue here because we would reach the same outcome under either parties’ POSA definition.” slip op. at 8

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

    “Whether to treat a preamble as a limitation is a determination ‘resolved only on review of the entirety of the patent to gain an understanding of what the inventors actually invented and intended to encompass by the claim.”’ In re Cruciferous Sprout Litig., 301 F.3d 1343, 1347 (Fed. Cir. 2002) (citation omitted). “In general, a preamble limits the claimed invention if it recites essential structure or steps, or if it is necessary to give live meaning and vitality to the claim.” Id. (citation and quotations omitted). This may be ascertained by review of the entirety of the patent to determine whether the preamble “discloses a fundamental characteristic of the claimed invention” as opposed to merely “stat[ing] a purpose or intended use.” Poly-Am., L.P. v. GSE Lining Tech., Inc., 383 F.3d 1303, 1310 (Fed. Cir. 2004). As Patent Owner points out, the ’197 patent is replete with references describing the invention as an optical analyzer. See Prelim. Resp. 24–25 (bullet pointing quotes from the Specification). The Specification begins by explaining that optical or “[p]article analyzers . . . are well known analytical tools that enable the characterization of particles on the basis of optical parameters such as light scatter and fluorescence.” Ex. 1001, 1:16–19. The Specification explains that “[t]he present invention” provides both “illumination optics for use in an optical analyzer” and “an optical analyzer incorporating the illumination optics of the present invention.” Ex. 1001, 2:3–4, 2:18–19. Claims 1–13, each of which recites an “optical analyzer” comprising a set of optical elements, are specifically directed to the latter. Id. at 9:55–10:59. The Specification further demonstrates that the preamble term is limiting by explaining that “the invention addresses a concern specific to” optical analyzers. See Deere & Co. v. Bush Hog, LLC, 703 F.3d 1349 1358 (Fed. Cir. 2012) (finding that the specification “demonstrates that the preamble phrase ‘rotary cutter deck’ is a limitation” because it “explains that the invention addresses a concern specific to rotary cutters”). The Specification explains that in a flow cytometer, i.e., an exemplary type of optical analyzer, “the excitation light from a laser . . . is focused onto a focal spot to illuminate the core stream (the fluid stream containing the particles to be analyzed).” Ex. 1001, 1:39–42. According to the Specification, “[a]ccurate focusing of the excitation light beam on the core stream is important,” “[o]ptimal performance is compromised if the focused light beam is not properly adjusted on the core stream,” and because the particles being analyzed are only a “few microns in size, the precision of the light beam adjustment also needs to be in the micron range.” Id. at 1:42–51; see also id. at 3:38–49 (explaining that “fine control over the focus spot” is useful in optical analyzers). The present invention addresses these concerns by providing an optical analyzer “adapted to focus an illumination beam onto a sample analysis region,” configured to obtain a “high degree of precision over the adjustment of the focal spot using less expensive lens adjusting mechanisms,” and comprising “detection optics for measuring the light emitted from the analysis region.” See id. at 2:18–23, 7:3–8. We also agree with Patent Owner that the recitation of an “optical analyzer” in the preamble informs the meaning of the phrase “a focusing lens . . . adapted to focus the light beam onto a focal spot within a sample analysis region” in the claim body. The term “sample analysis region” refers to a structural feature of the claimed “optical analyzer,” i.e., the area configured to contain the sample to be analyzed. This is confirmed by the Specification, which explains that in addition to illumination optics “[t]he optical analyzer will further comprise detection optics for measuring the light emitted from the analysis region. In a preferred embodiment, the optical analyzer is a flow cytometer, and the sample analysis region is a sample detection region in a fluid stream containing particles to be optically analyzed.” Ex. 1001, 2:21–26. In this regard, the preamble informs the meaning of “sample analysis region” by indicating that the recited “sample analysis region” is configured such that it can contain a sample and that light emitted from that region can be measured by the analyzer. See Deere, 703 F.3d at 1358 (explaining that “rotary cutter deck” in the claim preamble “informs the meaning of the ‘torsional stiffness’ limitation––the claimed structure must possess sufficient stiffness to withstand the torsional loads imposed by the operation of a rotary cutter”). By the same measure, holding that the “sample analysis region” need not be so configured would undermine the benefits the Specification indicates the recited illumination optics achieve. See Ex. 1001, 1:39–55, 2:30–48, 7:3–7 (explaining that “accurate focusing” is important because the sample to be analyzed may be very small and that the present invention obtains “precise positioning control” using less expensive components). The fact that the preamble informs the meaning of a term in the claim body, distinguishes it from “nonlimiting preamble terms” that “merely state a name or a use” by demonstrating that the optical analyzer recited in the preamble of the presently challenged claims is a “fundamental characteristic of the claimed invention.” Deere, 703 F.3d at 1358 (quoting Poly-Am., 383 F.3d at 1310).9 slip op. at 13

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

    “To interpret “stable,” we begin with how the term is used in independent claims 7 and 19. Both terms recite “stable” in relation to the pharmaceutical formulation as a whole by reciting “wherein the formulation is stable.” Ex. 1001, 189:62–190:27. From this, we conclude that the ordinary artisan, as defined above to have a relevant advanced degree and at least two years of experience in development or manufacture of therapeutic protein formulations, would have understood that the components of a “stable” formulation would maintain their integrity and desired function following preparation, including when stored as described. This meaning is supported by the following language in the specification pertaining to the disclosed pharmaceutical compositions: Pharmaceutical compositions according to the present invention are described in further details hereinbelow. In one aspect, the pharmaceutical compositions disclosed herein are physico-chemically stable and maintain the integrity of an antibody comprised in said pharmaceutical composition, for example when stored for 8 weeks at 40° C. as shown hereinbelow. Ex. 1001, 84:20–26. We also note, as Petitioner argued, that the prosecution history supports that the formulation components needed to remain functional during storage, and that Patent Owner cited to formulation integrity after a storage period of 8 weeks at 40° C as evidence of such integrity. Ex. 1004, 7380. As disclosed in the ’265 patent, Examples 9 and 12 measure function and identity of the components following storage to confirm formulation stability.” slip op. at 11

    “burden of showing that claim 7 or 14 lacks written description support in the priority application, which Petitioner has conceded provides the same support as the ’265 patent specification. In this regard, we agree that the reasoning in Fresenius likewise applies: there is no legal requirement that a patent specification must include test results or working examples demonstrating stability for every possible composition that is covered by the claims. Fresenius at 13, citing Ariad Pharms., 598 F.3d at 1352 (stating that “the written description requirement does not demand either examples or an actual reduction to practice”). Formulations 2 and 3, disclosed in the ’265 patent specification, which Petitioner acknowledges falls within the scope of claims 7 and 14 (Pet. 26–27 (citing Ex. 1002 ¶¶ 134, 135)), were shown to be stable for 8 weeks in a syringe. Moreover, the ordinary artisan was provided with guidance in making such formulations from the teachings of the specification and has additional knowledge from the art. See Ex. 1001, 85:32–94:35. Claims 7 and 14 identify specific structures (risankizumab) and required excipients within a defined pH range, which are stable as confirmed by testing results presented in the specification. Prelim. Resp. 33; Ex. 1001, 94:14–36. On this record, we conclude that the evidence presented does not establish that it is more likely than not that an ordinarily skilled artisan would not have reasonably believed that the inventors of the ’265 patent possessed the claimed subject matter, each limitation of which is demonstrated as supported in the specification. As we have interpreted the claim term “wherein the formulation is stable” to mean “wherein the formulation maintains the functional integrity of the antibody and other components, for example when stored for 8 weeks at 40° C,” the specification supports maintenance of functional integrity as shown by the stability of Formulations 2 and 3, including when stored for a period of time. For this reason, we find that Petitioner has not shown that the ordinary artisan would not have understood the inventors of the ’265 patent possessed the subject matter of claims 7 and 14 as of the filing date of the priority application.” slip op. at 23

    “We acknowledge that in the Fresenius case, the extensive testing disclosed in that specification supported the ordinary artisan’s ability to formulate stable compounds using such guidance, and that the specification here discloses less testing. See, e.g., Sur-Reply. 8–9. Nevertheless, it is Petitioner’s burden on this issue, and we are not persuaded that the concerns raised by Dr. Klibanov provide sufficient evidence of actual instability to justify institution on this record. See, e.g., Atlas Powder Co. v. E.I. du Pont De Nemours & Co., 750 F.2d 1569, 1577 (Fed.

In particular, we are persuaded that, on this record, Petitioner’s lack of evidence of instability of any formulation falling within the limitations of claim 14 indicates that Petitioner has not established sufficiently, for purposes of trial institution, that it is more likely than not that an ordinarily skilled artisan would not have been able to practice the full scope of claim 14 invention based on the teachings of the specification.” slip op. at 28
