Reason to reduce contaminant levels We agree with Patent Owner that Petitioner identifies no teaching in the prior art providing any reason to reduce levels of 6,7-dimethoxy-quinoline-4-ol specifically. And while Brown does teach a desire to form “substantially pure” compounds, Brown focuses on “at least about 90 wt.%” of the compound, then lists specifically “about 90, about 91, about 92, about 93, about 94, about 95, about 96, about 97, about 98, about 99 and about 100% wt. %.” Ex. 1003 ¶ 97.

    “to modify Brown’s process with Kubo to eliminate the added step. See, e.g., Id. ¶ 73. But even with that combination, Dr. Dichtel states only that a “POSA would have expected there to be a decrease in the amount of 6,7- dimethoxy-quinoline-4-ol at the end of cabozantinib (L)-malate’s synthesis that was attributable to hydrolytic degradation of the 4- (nitrophenoxy)quinoline intermediate by avoiding its use in the synthesis.” Id. ¶ 78. That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

    “In general, “a preamble is not limiting where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Catalina, 289 F.3d at 808 (quotation marks omitted). But even then, “[w]hether a preamble stating the purpose and context of the invention constitutes a limitation of the claimed process is determined on the facts of each case in light of the overall form of the claim, and the invention as described in the specification and illuminated in the prosecution history.” Applied Materials, Inc. v.

We determine that, read in view of the Specification, the preamble, even though it states an intended purpose, is limiting, because “it is necessary to give life, meaning, and vitality to the claim.” See Catalina, 289 F.3d at 808 (quotation marks omitted). The ’308 patent discloses “an adoptive cellular immunotherapy composition comprising a genetically modified helper T lymphocyte cell [i.e., CD4+ T cell] preparation that augments the genetically modified cytotoxic T lymphocyte cell [i.e., CD8+ T cell] preparation[’]s ability to mediate a cellular immune response.” Ex. 1001, 9:4–8, see also id. at 9:36–42 (disclosing that in some embodiments, an adoptive cellular immunotherapy composition “comprises an antigen-reactive chimeric antigen receptor modified naïve CD4+ T helper cell that augments the CD8+ immune response.”), 9:48–51 (the same).

Under this construction, Petitioner argues, the CD4+ T cells recited in claim 1 can be surface positive for CD62L, for CD45RA, or both. Id. (citing Ex. 1002 ¶ 87).

    “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

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.

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

  • BurdenDecided for patent owner

    “As an initial matter, we find Petitioner has insufficiently addressed the issue of inherent anticipation by Dixon (or any other prior art) and has done so in a merely conclusory manner. There is no dispute that Dixon (as well as the other asserted prior art) discloses angiogenic eye disorder treatment using the same drug (aflibercept), at the same dose (2 mg), administered in the same way (intravitreal injection), and administered at the same dosing regimen (an initial, a secondary, and a tertiary dose), as required by all challenged claims. See generally Pet.; Prelim. Resp. Petitioner relies on these facts, and the results of a phase 2 clinical trial that followed a different dosing protocol (one not claimed) to establish that the results limitations of claims 1, 26, and 29 are inherent to the phase 3 clinical trials (VIEW 1 and 2) with a dosing regimen that is claimed. See Pet. 38–39. Petitioner calls the claimed results limitations mere newly discovered results of a known process. Id. (citing Montgomery, 677 F.3d at 1381). As Patent Owner identifies, it is not so simple. The evidence of the results of the VIEW 1 and 2 trials itself (found in the ’572 patent) shows that some, but not all, patients treated with the claimed dosing regimen achieved “a gain in visual acuity” as recited by claim 1, “a gain in visual acuity” that is “as effective” “as monthly administration of 0.5 mg of ranibizumab” as recited by claim 26, or “maintaining visual acuity” “as effective[ly]” “as monthly administration of 0.5 mg of ranibizumab” as recited by claim 29. See Ex. 1001, 13:5–38 (Table 1). As Patent Owner points out, the ’572 patent’s described studies 1 and 2, when following the claimed dosing regimen (2Q8), were not always effective treatments––achieving mere maintenance (as opposed to improvement or “gains”) of vision 95.1% and 95.6% (respectively) of the time. Id.; see Prelim. Resp. 34–37 (citing Ex. 1001, 13:8–27; Ex. 1014, 4, 6; Ex. 1030, 9; Ex. 2021 ¶¶ 109–111; Ex. 2022). Thus, the evidence shows that, although most would, about 4–5% of patients (or, possibly, an even higher number based on Patent Owner’s cited evidence––Ex. 1030, 9) would not see the gains in visual acuity required by claims 1 and 26 or the maintenance in visual acuity required by claim 29. It is well established that “[i]nherency . . . may not be established by probabilities or possibilities” and “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” In re.

    “Relating to the claim construction, the Federal Circuit found that patent at issue was “clear” that the tissue fibrosis, recited by the claim as arrested or regressed by the otherwise recited treatment, was not the same as and did not necessarily accompany the symptom of erectile disfunction (taught in and the focus of the relied-upon prior art), although the former (fibrosis) may frequently result in the latter (disfunction). Id. at 1059. The Federal Circuit held that the “arresting or regressing” clause was more than a mere statement of intended result, but was a limitation carrying patentable weight because the phrase was drafted as a part of a separate step of the method rather than of the preamble, the “arresting or regressing” language demanded efficacy, and the efficacy was linked to specific treatment minimum duration and dosage. Id. at 1060–61. The patients exhibiting these two issues were not necessarily the same. In part because the Board did not consider the arresting/regressing result limitation in its unpatentability analysis, the Federal Circuit agreed with the patent owner that the Board’s findings were insufficient. Id. at 1064, 1067. The Federal Circuit found that that prior art reference relied upon in the Board’s decision for teaching the claimed treatment, and also relied upon to link the condition of fibrosis with the symptom of erectile dysfunction, did not teach treating a population of patients suffering from erectile dysfunction only because of a fibrosis condition and, even though such patients may have had fibrosis, it was not certain; and further found that other cited prior art did not make certain a link between fibrosis and such dysfunction. Id. at 1065–66. This, the Federal Circuit found, was error. We find in agreement with Patent Owner that the results limitations of the challenged claims are limitations and must be given patentable weight for the same reasons arresting or regressing a tissue fibrosis was a limitation in Los Angeles Biomed. Similarly, here the claims are directed to expressly required results of the administration of aflibercept to patients at 2 mg at an initial dose, in at least one secondary dose 4 weeks later, and in at least one tertiary dose 8 weeks later. Therefore, we find that in claim 1, “wherein the patient achieves a gain in visual acuity within 52 weeks following the initial dose,” is a limitation. Further, in claim 26, “wherein the method is as effective in achieving a gain in visual acuity as monthly administration of 0.5 mg of ranibizumab by intravitreal injection in human subjects with age-related macular degeneration at 52 weeks following the initial dose,” is a limitation. And, in claim 29, “wherein the method is as effective in maintaining visual acuity as monthly administration of 0.5 mg of ranibizumab by intravitreal injection in human subjects with age-related macular degeneration at 52 weeks following the initial dose,” is a limitation.” slip op. at 17

  • Skill levelOther

    “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

    “We agree with Patent Owner that “Interleukin 11 receptor α (IL- 11Rα) antibody” should not be construed to include antibodies that bind to IL-11Rα of non-human species but not to the human version of this protein because such a construction does not comport with the language of claim 1, which is clearly directed to treating a human subject. See Pause Tech. v. TiVo, 419 F.3d 1326, 1331 (Fed. Cir. 2005) (rejecting interpretation of claim element that ignored “other language appearing later in the claim” in stating that ‘“[p]roper claim construction . . . demands interpretation of the entire claim in context, not a single element in isolation.’”) (citing Hockerson– Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed.Cir.1999)). Construing this term to include antibodies that bind solely to non-human IL- 11Rα would be inconsistent with a claim directed to treatment of a human. Accordingly, for purposes of this decision, we construe “Interleukin 11 receptor α (IL-11Rα) antibody” to mean “any natural or synthetic, monoclonal or polyclonal antibody made using any animal system including phage, or fragment or derivative thereof, that binds to human IL-11Rα.”” slip op. at 9
