RulingsFinal written decision- Skill levelSkill level board ownDecided for petitioner
“As explained in our Institution Decision (Dec. Inst. 6–7), we do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner states a POSITA must have one to two years of postdoctoral research experience and Patent Owner’s definition requires at least five years of “research experience,” Patent Owner’s definition does not indicate a specific time for that research (i.e., it could include research during or after a doctoral program). Neither party addresses or contests the other party’s definition in their post-institution papers. See generally PO Resp.; Pet. Reply; PO Sur-reply. Accordingly, we find the parties’ respective definitions to be equivalent and 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. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). Moreover, we find that Dr. Shaner and Dr. Somers are both qualified to opine from the perspective of a skilled artisan as both are persons of at least ordinary skill in the art, based on either party’s definition. See Ex. 1002 ¶¶ 5–15; Ex. 2036 ¶¶ 5–11, App’x A; see also Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F. 4th 1369, 1376–77 (Fed.

- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed patent owner constructionDecided for patent owner
“Having considered the arguments and evidence presented at trial, we agree with Patent Owner that the inventors acted as their own lexicographer to define “effective amount” and that that definition governs its meaning. Phillips, 415 F.3d 1316 (“[O]ur cases recognize that the specification may reveal a special definition given to a claim term by the patentee that differs from the meaning it would otherwise possess. In such cases, the inventor’s lexicography governs.”). We, therefore, construe the term “effective amount” to mean “the amount of an herbicide required to achieve at least about 65% phytotoxicity of conventional rice (e.g., red rice) in field applications.” As explained further below, however, whether incorporated into the construction of “effective amount” or not, the claim language itself further requires that the “effective amount” encompass a specific range of amounts of herbicide and cause “less than 10%” injury to the mutant rice. See Ex. 1001, claim 1. We determine it is unnecessary to expressly construe any other claim terms for purposes of this Decision. See Wellman, 642 F.3d at 1361.” slip op. at 11
- Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateUnpatentable
“labels is akin to relying on literature that clearly provides, on its face, the missing disclosure, as in Falkner. Id. On the contrary, Patent Owner’s argument makes clear that the herbicide labels, by themselves, are insufficient to describe the claimed range limitation. Specifically, because the label ranges do not align with the claimed ranges, Dr. Somers had to make additional assumptions and inferences to support Patent Owner’s written description argument. For example, to calculate the potential effective amount range of herbicides, Dr. Somers applied several different “rules of thumb,” none of which are disclosed in the Mankin specification. See Ex. 2036 ¶¶ 34, 54. According to Dr. Somers, to determine the effective amount for a plant with an unknown response to an herbicide, a POSITA “would naturally test the lowest label (1X) rate of the herbicide, along with a few rates below (starting at about half-X) and above the 1X rate (up to 4X) of the herbicide, to determine the effective dose for this ‘uncharacterized’ plant.” Id. ¶ 34. Dr. Somers refers to this as a “dose response analysis.” Id. ¶ 53. In other words, to determine what the actual effective amount of herbicides should be, Dr. Somers explains that a POSITA would have to test the plants at these “rule of thumb” amounts to determine the effective range. Id. ¶ 34. Given the additional assumptions and inferences that must be made to the herbicide labels to arrive at the range limitations, we are not persuaded that relying on the extrinsic herbicide labels for written description support is proper in this case. That said, even if we were to allow Patent Owner to rely on the herbicide labels and the “rules of thumb” for determining the effective herbicide dose, Patent Owner admits that the ranges calculated from the herbicide labels are broader than the range limitations of the claims. See PO Resp. 39. As Petitioner notes, however, the Mankin Application does not provide any guidance as to whether the effective amount range of herbicide would include a 0.5x dose, a 2x dose, or the 4x dose, such that a POSITA could immediately discern the claimed range from the herbicide label.17 Pet. Reply 16.” slip op. at 30
- Expert testimonyPatent owner expert discountedDecided for petitioner
“Dr. Somers, however, relies on the label for Fusilade II, which is a different fluazifop-P-butyl herbicide with a different range of 52.98–103.96 g AI/Ha, which—not surprisingly—aligns more closely with the claimed range of at least 56–150 g AI/Ha. Ex. 2036 ¶ 52. We note that Fusilade II does not appear to be one of the listed herbicides in Table 1, whereas Fusilade DX is. Ex. 2034 ¶ 219 (listing “Fusilade, Fusilade 2000, Fusilade DX, ICI-A 00009, ICI-A 00005, SL-236, IH-773B, TF-1169, and Fusion” as examples of synonyms and trade names for fluazifop-P-butyl). Regardless, that the dose range differs for the same herbicide calls into question the credibility of Dr. Somers’s assertion that a person of ordinary skill in the art would have been able to discern the claimed range limitation by simply looking at the EPA-approved herbicide labels (and applying his “rules of thumb”).18, 19” slip op. at 33

“We begin by noting that the challenged claims do not recite that the nutritional supplements are “free of Vitamin A” or “free of all sources of Vitamin A.” Rather, independent claim 1 expressly recites that the supplement is “free of beta-carotene.” See Claim 1. Patent Owner urges us to expand the exclusion of beta-carotene to all forms of Vitamin A. That argument, however, lacks support on the current record. In particular, the support asserted by Patent Owner and its expert, Dr. Dorey, that “nutritional supplements include beta-carotene as Vitamin A equivalent,” see Prelim. Resp. 9–10 (citing Ex. 2001 ¶ 19), establishes little, on its own. Barker does not require the use of beta-carotene as its source of Vitamin A, nor does it limit the source or form of Vitamin A used. Rather, Barker discloses that several “[e]xamples of compounds having vitamin Aactivity or precursors thereof are retinol and esters thereof, such as retinyl palmitate; α- and β-carotene, β-cryptoxanthin, and lycopene.” Ex. 1011, 2:11–13. Thus, Barker discloses a number of exemplary compounds to supply Vitamin A to its nutritional supplement that are not beta-carotene. Accordingly, based on the current record, we disagree with Patent Owner’s argument that the challenged claims exclude all forms of Vitamin A and that Barker, therefore fails to anticipate those claims. Having considered the arguments and evidence at this stage in the proceeding, we are persuaded that Petitioner has shown sufficiently for institution that Barker discloses a nutritional supplement that is “free of beta-carotene.” Therefore, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing in showing that claims 1, 2, 5, and 9–12 are anticipated by Barker.” slip op. at 11

RulingsInstitution decision- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner
“Decision. See Ex. 3001, 12–23. In the -00881 Decision, challenged claim 1 of US 9,254,338 B2 (the “’338 patent”) recited preamble language identical to that recited in claim 1 of the ’681 patent, viz., “a method for treating an angiogenic eye disorder in a patient.” See Ex. 1001 col. 21, ll. 40–41; Ex. 3001, 7. The Board found that this preamble was limiting upon the remainder of the claim. Ex. 3001, 18. Specifically, the Board found that: Here, the claims are directed to methods of administering, i.e., using, a VEGF antagonist for an intended purpose of “treating an angiogenic eye disorder in a patient.” The Specification repeatedly characterizes the method as one for treating angiogenic eye disorders in patients. Apart from the preamble, the independent claims do not elsewhere recite or indicate any other use for the method steps comprising the administration of a VEGF antagonist. Thus, we determine that the preamble sets forth the essence of the invention—treating an angiogenic eye disorder in a patient. Additionally, we find that the preamble provides antecedent basis for claim terms “the patient” recited in the body of each independent claim, and “angiogenic eye disorders” recited in dependent claims 6, 7, 18, and 20. Indeed, without the preamble, it would be unclear to whom the doses of VEGF are administered. Thus, … in view of the evidence of record, namely, the claim language and the written description of the ’338 patent, we find that the preambles of method claims 1 and 14 are limiting insofar as they require “treating an angiogenic eye disorder in a patient.” Id. at 17–18 (citations omitted). We adopt this same reasoning here and find, for the purposes of this Decision, that the preamble of claim 1 reciting “[a] method for treating an angiogenic eye disorder in a patient” is limiting upon the claims.” slip op. at 9

“[W]hen the Specification explains that “[t]he amount of VEGF antagonist administered to the patient in each dose is, in most cases, a therapeutically effective amount,” and discloses that “a therapeutically effective amount can be from about 0.05 mg to about 5 mg,” we find that a POSA would have understood that any dosage amount within that range administered according to the invention may, in some cases, result in a detectable improvement in “one or more symptoms or indicia of an angiogenic eye disorder,” or be one that “inhibits, prevents, lessens or delays the progression of an angiogenic eye disorder,” or it may not. In either event, the VEGF antagonist would have been administered for the purpose of treating the eye disorder. In other words, the method of treating the patient with the eye disorder is performed upon administration of the VEGF antagonist to the patient for the purpose of achieving an improvement or beneficial effect in the eye disorder, regardless whether the dosage amount administered actually achieves that intended result. Id. at 21–22 (citation omitted). Furthermore, the Board found that: Patent Owner’s proposes that the claims require not only achieving a therapeutically effective result, but more specifically, achieving a “high level of efficacy that was noninferior to the standard of care by the time the patent was filed in 2011.” In the Sur-reply, Patent Owner describes a “highly effective treatment for angiogenic eye disorders” as “one that is on par to Lucentis or off-label Avastin and can produce visual acuity gains, not just slow vision losses.” The Specification refers to “a high level of efficacy” in one instance, i.e., in the “Background” section. The Specification does not describe there, or elsewhere that “treating,” in the context of the claims or in the art, requires achieving a “high level of efficacy” or providing results “on par to Lucentis or off-label Avastin.” Id. at 22 (citations omitted). We adopt the same reasoning here, and find that, for the purposes of this Decision, the evidence of record and the Specification support construing the preamble’s recitation of a “method for treating a patient with an angiogenic eye disorder” as meaning administering a compound, i.e., the recited VEGF antagonist, to such patient for the purpose of improving or providing a beneficial effect in their angiogenic eye disorder, but does not require a “high level of efficacy,” as proposed by Patent Owner.

“construction of the claim terms “initial dose,” “secondary dose,” and “tertiary dose.” Petitioner proposes adoption of the definitions expressly set forth in the Specification of the ’681 patent, viz., that the initial dose is the dose “administered at the beginning of the treatment regimen,” and is followed by the secondary doses “secondary doses” are “administered after the initial dose,” and the tertiary doses are “administered after the secondary doses” and may be distinguished from the secondary doses “in terms of frequency of administration.” Ex. 1001 col. 3, ll. 36–44. We do not find persuasive Patent Owner’s argument that the definition of these terms require a high, or otherwise defined, degree of efficacy. As we stated in the -00881 Decision: Based on those express definitions in the Specification, we do not find cause to construe the terms differently. In particular, we do not find that the Specification requires the “tertiary doses” to maintain any efficacy gain achieved after the initial and secondary doses, or that the term suggests any specific level of efficacy. The Specification unequivocally states that “[t]he terms ‘initial dose,’ ‘secondary doses,’ and ‘tertiary doses,’ refer to the temporal sequence of administration of the VEGF antagonist.” Ex. 3001, 25 (emphasis added). We see no need or reason to upend this construction now and, for the purposes of this Decision, we adopt Petitioner’s proposed definition of the claim terms “initial dose,” “secondary doses,” and “tertiary doses” as the express definition provided by the ’681 Specification.” slip op. at 13

Rather, we find more persuasive Dr. Day’s testimony that Gille503 satisfies Element 22[h] because one of ordinary skill in the art would have understood that “comparisons performed by the feedback loop would detect a change in blood pressure either when current sensed blood pressure ceases to equal the target blood pressure, or when current sensed blood pressure begins to equal target blood pressure after previously not equaling the target pressure.” Ex. 1014 ¶ 114; see generally, id. ¶¶ 111–119.

“Patent Owner agrees with Petitioner’s first portion of the definition, specifically, that a person of ordinary skill in the art would have had at least “an undergraduate or graduate degree in genetics, genomics, and/or animal breeding, along with several years of relevant applied research and/or industry work experience in the same fields, including in swine.” PO Resp. 16. Patent Owner, however, objects to the inclusion of the second portion of Petitioner’s definition because it is “improperly injecting a purported knowledge of the claimed invention into the definition of a” person of ordinary skill in the art. Id. at 17 (citing Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355, 1362 (Fed. Cir. 2016); In re Sang Su Lee, 277 F.3d 1338, 1345 (Fed. Cir. 2002)); Sur-reply 2–4. Petitioner responds, that its proposed definition reflects the level of skill in the art as supported by the various cited prior art. Pet. Reply. 5. Having considered the arguments and evidence, we agree with Patent Owner that Petitioner’s definition of one of ordinary skill in the art unnecessarily recites specific knowledge, whereas the art itself demonstrates the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). Accordingly, we agree with Patent Owner and determine that one of ordinary skill in the art is a person having at least “an undergraduate or graduate degree in genetics, genomics, and/or animal breeding, along with several years of relevant applied research and/or industry work experience in the same fields, including in swine” and this definition is reasonably consistent with the ’734 patent and the prior art of record.” slip op. at 7

“Having considered the record as a whole, we determine that Petitioner’s position with respect to the interpretation of “genetic nucleus” is reasonably supported within the record. At oral argument, however, Petitioner acknowledged that omitting the language “wherein certain offspring of the herd are used for breeding within the herd” from the claim construction would not change whether the challenged claims read on the applied references. See Tr. 14:6–16:28. Because the additional language proposed by Petitioner is unnecessary in order to resolve the disputed issues in this case, we do not adopt it here. We, therefore, construe “genetic nucleus” as an animal herd comprising one or more lines and positioned at the top of a multi-level pyramidal hierarchy of herds in a commercial herd breeding structure. 2. Remaining Claim Terms We find that it is unnecessary to expressly construe any remaining claim terms for purposes of this Decision. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed.

“We agree with Patent Owner that in an anticipation challenge under 35 U.S.C. § 102, Petitioner cannot rely upon specific disclosures in Maxwell or Gardner based on the generic reference to these publications cited Dekkers. Merely citing Maxwell or Gardner in association with sorting sperm as discussed in Dekkers is not incorporation by reference with any level of particularity. See PO Resp. 29 (citing Callaway Golf Co. v. Acushnet Co., 576 F.3d 1331, 1346 (Fed. Cir. 2009) (To incorporate matter by reference, “a host document must contain language clearly identifying the subject matter which is incorporated and where it is to be found; a mere reference to another application, or patent, or publication is not an incorporation of anything therein.” (internal quote and citations omitted, emphasis in original)); see also Cook Biotech Inc. v. Acell, Inc., 460 F.3d 1365, 1376 (Fed. Cir. 2006) (“To incorporate material by reference, the host document must identify with detailed particularity what specific material it incorporates and clearly indicate where that material is found in the various documents.”). The disclosure in Dekkers relied on by Petitioner recites: “The technique involves the separation of spermatozoa carrying either X or Y chromosomes (Maxwell et al., 2004; Garner, 2006).” Ex. 1004, 396. We note that Maxwell and Garner are review articles discussing the state of sperm sexting technology generally. See Ex. 1005; Ex. 1006. We agree with Patent Owner that the generic citation to these review articles as set out in Dekkers is not an incorporation by reference of any specific detail from these articles. Unlike the disclosures at issue in Callaway and Cook, Dekkers does not use language such as “reference is made to” (Callaway, 576 F.3d at 1346) or “the disclosure of which is expressly incorporated herein by reference” (Cook, 460 F.3d at 1376) in conjunction with identifying a particular portion of the cited reference that our reviewing court has held to be sufficient to indicate to one of skill in the art that the referenced material is fully incorporated in the host document. Because Dekkers does not incorporate by reference the level of sorting accuracy as required by the claims – at least 80% – the preponderance of evidence of record does not support Petitioner’s position the Dekkers anticipates claims 1–5 of the ’734 patent.” slip op. at 19

“We find that Petitioner has the better position. Here, Patent Owner is identifying the scope of the invention as the commercial tier at the bottom of the pig production pyramid. However, the scope of the claimed invention is directed to the substantially smaller herd sitting at the top of the commercial pig breeding pyramid. As explained in Teva, “[t]he reasonable-expectationof-success analysis must be tied to the scope of the claimed invention. See Allergan, Inc. v. Apotex Inc., 754 F.3d 952, 966 (Fed. Cir. 2014) (“[F]ailure to consider the appropriate scope of the ... claimed invention in evaluating the reasonable expectation of success ... constitutes a legal error ....”); see also Intelligent Bio-Sys., Inc., 821 F.3d at 1367.” Teva, 18 F.4th at 1381. Above, we construed “genetic nucleus” as an animal herd comprising one or more lines and positioned at the top of a multi-level pyramidal hierarchy in a commercial herd breeding structure. See above II.C.1. The herd at the top of the pyramid comprises far fewer animals than the multiplication and production tiers. See Ex. 1097 ¶¶ 65 (“the relatively smaller herd size of the genetic nucleus (e.g., hundreds or thousands as compared to millions at the production level) makes the use of sexed semen far easier than in vastly larger multiplier and production herds”), 84; Ex. 1096, 36:21–37:4; Ex. 2004, 39:6–22 (millions of animals at the production level). Petitioner contends that sperm sorting combined with lowdose insemination would have been practical for the much smaller herds found at the genetic nucleus. Pet. Reply 21. Both Maxwell and Garner reasonably suggest that deep-uterine insemination (DIU) allows for the use of sex sorted boar sperm. See Ex. 1005, 88; Ex. 1006, 952. Patent Owner admits that the use of sex-selected semen in the laboratory environment works. See PO Resp. 39. Even if the genetic nucleus (i.e. nuclear herd) comprises in excess of 100 or even 1000 animals it is not clear why using artificial insemination in conjunction with sex-selection would not work at the level of the genetic nucleus as argued by Patent Owner. See PO Resp. 39 (“sexed semen has not been implemented outside of a research setting”). Absolute predictability is not necessary to reach an obviousness determination; only a reasonable expectation of success is needed. Pharma Stem Therpeutic, Inc. v. ViaCell, Inc., 491 F.3d 1342, 1360 (2007); In re Kubin, 561 F.3d 1351, 1360 (Fed. Cir. 2009); In re O’Farrell, 853 F.2d 894, 903–904 (Fed.

In particular, Dekkers teaches that sorted sperm can be used for artificial insemination. Specifically, acknowledging that “new developments in sperm sexing technology allow for the production of either male or female offspring for sire or dam lines, and this can be very useful for the nucleus and multiplication tiers.” Ex. 1004, 396; Ex. 1002 ¶ 48; see also Ex. 1055, 80 (“The main application by pig producers is for the use of sex-sorting technology in nucleus herds, particularly for producing female lines.”).

“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

“recited in the challenged claims. In sum, considering the record as a whole, we agree with Dr. Wang’s testimony that one of ordinary skill in the art would have found the challenged claims obvious in view of Stafford. Ex. 1003 ¶¶ 348–370. We also do not find persuasive Patent Owner’s argument that a person of ordinary skill in the art reading Stafford would have had serious concerns regarding whether R338L would be expressed. As discussed above, Stafford discloses successful expression of R338A in vitro. As Dr. Wang explains, given that Stafford demonstrated in vitro expression for numerous other variants in the 330–338 helix region of FIX, only R338P showed reduced expression, and unlike leucine, “proline [P] is a known ‘helix breaker.’” Ex. 1004, 14–15; Ex. 1100 ¶¶ 113–116, 225; see also Ex. 1100 ¶¶ 117–121. As such, we agree with Dr. Wang that one of ordinary skill in the art would not have expected difficulties in the expression of R338L. We also find unavailing Patent Owner’s argument that a person of ordinary skill would not have expected in vivo expression of FIX-R338L at levels similar to that of wild-type FIX. To the contrary, Schuettrumpf supports a conclusion that a person of ordinary skill would have expected that gene therapy with FIX-R338A expressed in vivo from liver cells at levels similar to wild-type FIX.

Ex. 2114, 53:13–55:14; Ex. 1100 ¶¶ 113– 16; see also Ex. 1001, 4:45–58 (’180 patent’s teaching that it was expected that conservative amino acid substitutions (e.g. alanine and leucine) “would not change phenotype of the proteins”). We do not find persuasive Patent Owner’s argument that a person of ordinary skill in the art reading Stafford would have had serious concerns regarding whether R338L would be active. To the contrary, we credit Dr. Wang’s testimony that one of ordinary skill in the art would have expected the R338L variant to exhibit higher activity than wild-type Fix based, for example, on Stafford and Schuettrumpf showing that R338A exhibited higher activity in vitro and in vivo, respectively, and the similarities between alanine and leucine. See, e.g., Ex. 1003 ¶¶ 40, 42, 158, 219, 383, Ex. 1100 ¶¶ 101–112; see also Ex. 1094 ¶¶ 41–45, Ex. 1100 ¶¶ 23–36 (Dr. Pederson’s explanation of why one of ordinary skill would have expected replacing arginine 338 with leucine would have a similar effect as replacing it with alanine).

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
