      “B. LEVEL OF ORDINARY SKILL IN THE ART In determining the level of ordinary skill in the art, various non- exhaustive factors may be considered, including: “(1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field.” Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, F.2d 693, 696 (Fed. Cir. 1983). Petitioner contends that a person of ordinary skill in the art at the time of the invention (“POSITA,” “PHOSITA,” or “skilled artisan”) “would have the equivalent of an undergraduate degree in computer science, engineering, operations research, or similar discipline, along with one year of experience in computer programming” and that “[t]he more education one has, the less experience needed to attain an ordinary level of skill[, and] . . ., more experience in the field may serve as a substitute for formal education.” Pet. 9 (citing Ex. 1003 ¶ 32).

      “We generally agree with Petitioner that the assumptions and approximations made in the calculations described in the ’397 patent to determine the external surface area of the components of the litter render the computations only a general approximation of the respective surface areas. See Pet. Reply 9–12. We need not, however, reach the issue of whether the 47% surface area limitation requires the use of the multi-step method disclosed in the ’397 patent because Petitioner followed that methodology in its arguments and evidence in its Reply. See Pet. Reply 13. Importantly, Patent Owner agrees that Petitioner followed the approach set forth in the ’397 patent, and argues that we need not construe “external surface area” to resolve any dispute between the parties. See PO Sur-reply 23–24 (arguing that we need not “determine whether ‘total external surface area’ must be determined using the same multi-step approach” in the ’397 patent to resolve the controversy because “the only calculation of external surface area relied on by Petitioner was presented in the Reply and it followed the methodology of the [’]397 Patent”); PO Supp. Sur-reply 2 (same).

      “review of the record, we find that Petitioner fails to articulate an adequate rationale for the combination of Goss and House. The Petition contains only a single sentence addressing the issue, without any citation to record evidence or declaration support. See Pet. 46. In addition, the assertion merely states the conclusion that a “PHOSITA would understand that there is a rational underpinning to combine the teachings of Goss and House as required under patent law because both are related to cat litter having similar characteristics.” Id. This assertion, at most, addresses the fact that Goss and House are in the same field or that they are analogous art, but does not explain why a PHOSITA would have been motivated to combine Goss and House. See id. In addition, the Petition lacks sufficient explanation of how Petitioner proposes to combine Goss and House. See Pet. 46–53. Instead, when Petitioner relies on House in this challenge, it appears to be a back-up argument in the event that we find Goss fails to disclose the limitation. Merely stating that Goss and House both disclose a limitation does not explain which aspects of House Petitioner proposes adding to Goss or what the resulting litter composition would look like. See id. The details of the resulting litter based on the combination of Goss and House matter here because it could impact whether all limitations of a given claim are satisfied by the combination. For example, Petitioner relies exclusively on specific examples from Goss for the 47% surface area limitation, but adding some aspects of House’s litter components to meet other limitations could undermine Petitioner’s reliance on Goss’s specific examples. The failure of the Petition to set forth a specific combination elides these issues. See Pet. 46–51. Petitioner’s Reply arguably addresses some of these concerns by providing a more fulsome motivation section, backed by new expert testimony, and specific litter examples based on Goss and various cellulose filler materials allegedly disclosed by House. See Pet. Reply 24–25 (citing Ex. 1013 ¶ 7); see also PO Sur-reply 18–22 (arguing that Petitioner’s Reply still fails to articulate an adequate motivation to combine). This analysis goes far beyond the limited analysis in the Petition, and Petitioner provides no reason why it could not have been included in the Petition. See Pet. Reply 24–25.

    • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)UnpatentableUnpatentable

      “Patent Owner makes a number of arguments, but we do not find them persuasive enough to undermine Petitioner’s showing based on Ms. Borgese’s analysis. Patent Owner’s primary argument stems from its assertion that the bulk densities vary depending on a number of variables and that Ms. Borgese bases her ranges on documents, the technical data sheets for FS-40 and the ’397 patent for BL(2), that have bulk densities that are not the “same” as the bulk densities for FS-40 and BL(2) in Goss due to the passage of time, differences in where the clay was mined, how the clay was processed, and how the bulk density was measured. See PO Resp. 18– 19, 21–33; PO Sur-reply 2, 5–9. We do not view Petitioner’s challenge as based on the premise that the FS-40 clay referenced in the technical data sheets and Blue Mountain clay in the ’397 patent are the exact same as the FS-40 and BL(2) clays in Goss, but instead the clays and their bulk densities are similar enough that they will fall within the bulk density ranges Petitioner uses in its calculations. See Pet. 21–23, 68; Pet. Reply 6–7, 10. As a result, Patent Owner’s repeated assertions that the clays or their properties are not the “same” or processed “exactly the same” fail to engage 5 Patent Owner suggests that Petitioner fails to meet the inherency standard because Ms. Borgese uses the term “potential” when describing the bulk density range of BL(2). See PO Resp. 32 (citing Ex. 1003 ¶ 117). We do not read Ms. Borgese’s opinion in the same manner. Instead, we read the reference to “the potential bulk density range of BL(2), 35–47 lbs/ft3” as referring to any bulk density within that range, not that there is only the mere potential that the bulk density may fall within that range. See Ex. 1003 ¶ 117. Petitioner’s argument that the bulk densities were at least similar, such that that they fall within the ranges Petitioner uses. See, e.g., PO Resp. 4, 21–24, 30–31; Ex. 2009 ¶¶ 97–98 (Dr. Johnston limiting opinion to whether the clays are the “same”). As an example, when asked about the potential differences in bulk density between Goss’s filing date in 1997 and the 1999 technical data sheet, Ms. Borgese states that “[b]entonite clays have not changed significantly in a period of two years.” Ex. 2008, 24:7–15; see also Ex. 1003 ¶¶ 202–203 (opining that “modest difference in particle-size distribution between FS-40 disclosed in Goss [and] . . . the FS-40 Information Sheet ’99 only minimally impacts the bulk density”). Given Ms. Borgese’s personal experience making animal litters and using bentonites, we view her testimony as credible absent some evidence that any differences in bulk density would fall outside the ranges she uses. Patent Owner provides no such evidence. Nearly all of Patent Owner’s evidence goes to whether the clays and bulk densities would be the exactly the “same” in Goss as in the sources that Ms. Borgese relies on, and do not address how similar the bulk densities would be and do not attempt to establish that there are bulk densities for Goss’s FS- 40 and BL(2) clays that would fall outside the ranges Ms. Borgese uses. In the rare instances where Patent Owner does argue that the bulk densities would not be similar, or would not fall within Dr. Borgese’s ranges, Patent Owner fails to cite any evidence to support the assertion.

Pet. 4–5; PO Resp. 14. That definition presumes “experience in animal litter process development” and “familiarity with the composition and chemistry of various clays used in animal litter (including sodium bentonite).” Pet. 4–5. We find Ms. Borgese’s education and first-hand experience in animal litter process development, including experience with bentonite, sufficient to testify credibly as to the known bulk densities of the bentonite clays at issue in the case. As to Goss’s FS-40 sodium bentonite clay made by Wyo-Ben, Ms. Borgese opines that the range of bulk density for the material in Goss is between 58–64 lb/ft3 based on Wyo-Ben’s own technical data sheets from 1999 and 2002, which “describe the same (or similar) FS-40 (‘sodium bentonite’) composition.” Ex. 1003 ¶¶ 82–83, 106, 117; Pet. 21–22, 35. Then, in an effort “to be conservative in [her] analysis,” Ms. Borgese uses a broader range of 55–65 lb/ft3 for Goss’s FS-40 in her calculations. Ex. 1003 ¶ 117. Even when pushing her assumptions in directions that would result in the lowest possible external surface area percent for sodium bentonite, all of the calculations across the full range of potential bulk densities still meet the 47% surface area limitation. Id. ¶¶ 117–122; Pet. 43–46. Based on our review of the arguments and evidence, we find Ms. Borgese’s testimony as to the range of Goss’s FS-40 bulk density credible and persuasive.” slip op. at 25

See PO Resp. 20; PO Sur-reply 13. While Patent Owner seeks to exclude these documents, it fails to follow our rules applicable to such efforts. Our rules require objections to evidence to be filed within specific timeframes, and a “motion to exclude evidence must be filed to preserve any objection.” 37 C.F.R. § 42.64(c).

Nor did Patent Owner “identify the objections in the record” in support of its “motion.” Id. In addition, Patent Owner fails to cite any authority that permits what amounts to a motion to exclude within the confines of the merits briefing, which forced Petitioner to devote space in its merits brief to opposing the motion to exclude. See id.; Pet. Reply 19–23. Under these circumstances, we deny the motion as procedurally improper. In addition, even if we reached the merits, we would not exclude the documents or Ms. Borgese’s opinions based on them given that she reasonably relied on the technical data sheets as reliable sources of bulk density data provided by Wyo-Ben, the manufacturer of the clays in question.

      “We decline to adopt Patent Owner’s construction because it improperly reads into claim 5 a requirement that the specification and claim language do not support. The specification passages relied on by Patent Owner do not expressly state that a vehicle independent state must be determined while the device is inside a vehicle, and contrary to Patent Owner’s argument, they also do not necessarily imply that. For example, the descriptions of “vehicle independent movement” and “vehicle independent event” in the specification (see Ex. 1001, 1:16, 42) refer to “phone falling to the ground.” “Falling to the ground” implies that the phone may be outside a vehicle, not inside. Further, the specification’s reference to detecting a vehicle dependent state “while also” recognizing a vehicle independent event does not necessarily imply that the vehicle dependent state and vehicle independent event are being detected simultaneously, as Patent Owner argues. In the language of claim 5, a “vehicle independent state” is recited in the determining step (step c), and the requirement that the portable device is located “inside a vehicle” relates to creation of an operation indicator, as part of the detecting step (step b). Patent Owner does not dispute this, and agrees that a portable device “not in the vehicle” can satisfy the determining step (step c). Tr. 73:5–8. Patent Owner, however, argues step c’s recitation that a “vehicle independent state” is based on step b’s “predetermined criteria” creates a link between “vehicle independent state” and step b, and thus an “express requirement” in step c that the device is located inside the vehicle. See Tr. 73:8–26, 76:1–3. We decline to read this requirement into the claim language. Although the claim language states that determining a “vehicle independent state” is based on “predetermined criteria,” and step b describes comparing “predetermined criteria” to an “operation indicator” that is created when the device is inside a vehicle, it does not limit the step of determining a vehicle independent state to a time when the portable device is inside a vehicle. Accordingly, we construe “vehicle independent state” to mean a state triggered when the portable device is moved independently of the movement of the vehicle.” slip op. at 23

      “Petitioner contends that: A person of ordinary skill in the art (“POSITA”) at the time of filing the ‘228 Patent would have been a person having a bachelor's degree in science or engineering, for example in the fields of chemistry, chemical engineering, or biomedical engineering, with undergraduate research experience, coupled with at least three years of industry experience, that linked the fabrication of fibrous polymeric materials to performance requirements for scaffolds for the promotion of proliferation of biological cells and the growth and/or reconstruction of biological tissues. Pet. 11–12 (citing Ex. 1002 ¶¶ 112–116). In response, Patent Owner notes that all challenged claims recite electrospun fibers but that Petitioner’s proposed level of skill “requires (1) no coursework, training or experience with electrospinning and (2) improperly focuses on scaffolds for the promotion of proliferation of biological cells and the growth and/or reconstruction of biological tissues.” PO Resp. 7 (citing Ex. 2001, ¶¶ 38–39). But Patent Owner then concedes that this “difference is immaterial to deciding the issues raised by the Petition.” Id. at 8.” slip op. at 9

      “Upon review, we are unpersuaded that Petitioner has improperly mixed and matched disclosures from Johnson to arrive at an anticipatory reference. Patent Owner is correct that Petitioner primarily relies on Example 1 as evidence for the method by which its scaffold is made. But the disclosure found in paragraph 98 is not a “distinct” teaching of the type described in Net MoneyIN; rather, it is a general description of the structures that may be created by Johnson’s method: “A scaffold may comprise any number of layers, including about 1 layer, about 2 layers, about 3 layers, about 4 layers, about 5 layers, and so on.” Ex. 1009 ¶ 98. Patent Owner has not directed us to anything in the disclosure of Johnson that indicates that this is a “distinct” teaching or embodiment, instead of a general description of the types of scaffolds that Johnson encompasses. We see no reason why the general disclosures regarding Johnson’s scaffolds should be limited to specific embodiments, or precluded from applying to the method of Example 1.” slip op. at 14

      “We are unconvinced by Petitioner’s arguments and evidence. While we recognize that the range of claim 3 is very broad, and it is possible that scaffolds having fiber diameters as set forth in Johnson could have a mean pore size falling within the range, inherency “may not be established by probabilities or possibilities.” Par Pharm., Inc. v. Twi Pharms., Inc., 773 F.3d 1186, 1196 (Fed. Cir. 2014). Nor does Petitioner sufficiently explain why a person of ordinary skill in the art would have understood the process of Example 1 to necessarily result in the claimed mean pore size. We are also persuaded by Patent Owner’s argument that Boland 2005’s disclosure of a fiber diameter similar to Johnson’s that nevertheless falls outside the claimed mean pore size range. We note that Petitioner never addresses Boland 2005 in its Reply. 4. Conclusion as to Anticipation For these reasons, we find that Petitioner has met its burden of showing that claims 1, 2, 4, 5, and 13 are anticipated by Johnson, but has failed to meet its burden as to claim 3.” slip op. at 18

      “Neste argues that REG’s proposed level of skill in the art is “unreasonably high” and instead proffers that “a person of ordinary skill in the field of biofuel engineering and processing as of Feb. 15, 2011 would have had a degree in chemical engineering or chemistry and at least two to three years of experience with processes for manufacturing hydrocarbons from bio renewable feedstocks.” PO Resp. 6–7 (citing Ex. 2029 ¶ 31). Neither party indicates that the outcome of any arguments made in this case would change depending on the level of ordinary skill in the art. We agree with the parties that the ordinarily skilled artisan, in February 2011, would have had at least a degree in chemical engineering or chemistry and would have had several years of experience in processing and refining biofuels. We need not parse the particular amount of education or experience given that neither party asserts this determination would have had any effect on the arguments or analysis in this case. Further, we find that the prior art of record reflects 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).” slip op. at 8

      “We have again reviewed the record and the parties’ arguments, and again decline to import into the claim a requirement that the bio oil must be pre-treated. As we discussed in our institution decision, nothing in the ’185 patent indicates that the definition of bio oil is so limited. And we note that certain dependent claims of the ’185 patent, for example claim 21, specifically recite a pre-treatment step, leading to the conclusion that the bio oils of the independent claims are not limited to only pretreated bio oils. Neste’s new evidence introduced during trial is extrinsic to the patent, based on the testimony of Dr. Klein regarding the criticality of the iron content range. See PO Resp. 3 (citing Ex. 2029 ¶¶ 35–36, 38). In any event, we fail to see how the criticality of the claimed range mandates that the bio oil be pretreated prior to undergoing the claimed process. While Dr. Klein testifies that it is “clear from the ‘185 patent [that] a bio oil feed must be pretreated to render it suitable for commercial hydrotreatment” (Ex. 2029 ¶ 35), the portion of the patent he cites for this proposition states only that “bio-based feedstock (glyceride oil) to be used as feed material for hydrotreatment reaction can be purified to iron content of less than 1 to 0.2 w-ppm.” Ex. 1001, 4:50–55 (emphasis added). But this statement does not address the use of a bio oil that already contains an iron content within the claimed range, which therefore would not need purification. Indeed, the ’185 patent discusses “experiments with palm oil having very low level of impurities.” Ex. 1001, 4:45–46. Based on the foregoing, we maintain our view that the claim term requires no construction beyond its express language. The bio oil to be used in the method of claim 1 may be pretreated to achieve the claimed iron content, but pretreatment is not required by the claim.” slip op. at 11

      “The intrinsic record of the ’185 patent contains no indication that bio oil intermediate was a new term coined to signify a specific class of bio oils, as Neste contends. The written description contains a section devoted to providing specific definitions for terminology, including “bio oil,” “glyceride oil,” and “hydrotreatment.” Ex. 1001, 3:28–4:7. There is no mention of a bio oil intermediate, which would be expected if the inventors had intended to coin a new term. The only use of “intermediate” in the entire written description is as follows: “disclosed is a glyceride oil intermediate, which intermediate consists of glyceride oil from at least one renewable source and the iron content of said glyceride oil is less than 1 w-ppm.” Id. at 4:64–67. The sentence preceding that one states only that the “purification result can be obtained (depending on used feedstock) using pretreatment methods.” Id. at 4:61–62 (emphasis added). As can be seen, there is no mention in this passage that the “glyceride oil intermediate” must be pretreated, and no indication it is a novel term coined by the inventors. In any event, Neste has not given us reason to depart from the general presumption that a claim preamble is not limiting. The body of claim 6 recites a structurally complete invention, defining the bio oil intermediate according to its iron content. There is no reason to rely on the preamble of the claim for any structure, or for antecedent basis for any claim term. Therefore, we conclude that the preamble does not “breathe life and meaning” into the claim, but rather recites an intended use for the structurally complete invention recited in the body of the claim. As such, we decline to adopt Neste’s modified construction of the claim term, and maintain our prior construction of claim 6’s preamble.” slip op. at 14

      “Upon evaluation of the record as a whole, we believe Neste has the better argument, and conclude that the iron content of the bio oil in claim 1 should be determined when the feed is introduced to the catalyst bed. This interpretation is, most importantly, reflected in the structure of the claim. Claim 1 contains a single process step, of “subjecting a bio oil . . . to a hydrotreatment process.” Immediately following this process step is a wherein clause that requires the iron content of “said bio oil” to be within a certain range. The necessary implication of this claim structure is that “said bio oil” is referring to the substance that is being subjected to the hydrotreatment process, meaning the iron content that is relevant to the claim is the iron content at the time of hydrotreatment with a catalyst. The claim, as a comprising claim, does not exclude the presence of other treatment steps such as purification or dilution, but the structure of the claim does imply that these additional steps should be performed prior to determining whether the iron content of the feed is within the claimed range.” slip op. at 20

      “A reference must be considered for everything that it teaches, not simply the described invention or a preferred embodiment.” In re Applied Materials, Inc., 692 F.3d 1289, 1298 (Fed. Cir. 2012). When read in its entirety, Sheesley teaches the claimed limitation. To illustrate this point, we begin by reproducing Sheesley’s Figure 5, below: Figure 5 depicts empty containers being filled with proppant after being placed on a rail car for transport. Although Figure 5 depicts the empty containers placed on a rail car, rather than on a road vehicle, as required by the claim, Sheesley’s disclosure is not limited to rail cars, as Patent Owner contends. Specifically, Sheesley discloses that rail is merely one of many modes of transportation, including trucks. Ex. 1005 ¶ 78 (“Modified cargo containers 270 can be loaded on a ship 272, barge 274, rail 276, or a flatbed truck trailer 278”).
