    “Synthes USA, LLC v. Spinal Kinetics, Inc., 734 F.3d 1332, 1344 (Fed. Cir. 2013). And, although there are no bright-line rules for the amount of disclosure needed in an unpredictable art, that amount “necessarily changes with each invention” and “changes with progress in the field.” Ariad, 598 F.3d at 1351. Here, we find that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. Thus, we conclude that the ’525 application requires a more-detailed disclosure than would be required in a predictable field to adequately demonstrate possession of a heat-transfer composition consisting essentially of HFO-1234yf and PAG for use in AAC. (iii) Disclosure in the ’525 Application With these background findings in mind, we now turn to the four corners of the ’525 application—and we find that the ’525 application does not contain the detailed disclosure needed in this case to reasonably convey possession of a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for use in AAC.” slip op. at 37

Thus, we find that Patent Owner does not contest that a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for AAC was in public commercial use before the March 26, 2014, filing date of the ’017 patent. Accordingly, we find that Petitioner’s evidence, together with Patent Owner’s concessions, demonstrates by a preponderance of evidence that the claimed subject matter of the ’017 patent was in commercial use before its March 26, 2014, effective filing date. See Ex. 1002 ¶¶ 399–409. In particular, as to claims 1, 3–10, 12, 13, and 15–20, we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant AAC composition of the Ford Transit Custom Bus, the Mazda CX 5 (2.0i and 2.2D), and the Opel Mocca used HFO-1234yf and a PAG lubricant as early as 2012. Ex. 1002 ¶ 399 (citing Ex. 101324, 2, 38, 55, 70). We also credit Dr. Brown’s 24 Behr Hella Services, Refrigerant and Oil Filling Quantities Passenger Cars & Commercial Vehicles 2014–15.

Id. at 2–3. Petitioner and Dr. Brown direct us to the Sevice Guide’s entries calculations, which show that the Ford Transit Custom Bus had an AAC refrigerant-lubricant composition of 26.7% of PAG lubricant and 73.3% of HFO-1234yf (Ex. 1002 ¶ 401 (citing Ex. 1013, 38)); the Mazda CX 5 2.0i had 16.7% PAG lubricant and 83.3% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 55)); the Mazda CX 5 2.2D had a 17.5% PAG lubricant and 82.5% HFO-1234yf (id.); and the Opal Mocca had 11.6% PAG lubricant and 88.4% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 70)). As to dependent claims 2, 11, and 14, which all require that the lubricant is present “in an amount from about 30% to about 50% weight,” we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant composition of the Ford Transit Custom Bus recited lubricant amount. Ex. 1002 ¶ 403. In particular, we agree with Dr. Brown that, because the lubricant accounts for 26.7% of the AAC refrigerant-lubricant composition in the Ford Transit Custom Bus, the lubricant makes up “about 30%” of the refrigerant-lubricant composition as claimed.

    “We agree with Petitioner that the ’525 application’s statement that the compounds are “adaptable for use” weighs against a finding of adequate written description. First, “adaptable for use” is vague, as Dr. Bivens acknowledges. See Ex. 1177, 151:15 (testifying that “adaptable for use can have a wide range of meaning”). Second, the ’525 application gives no direction on how a skilled artisan would need to adapt any particular composition for use in AAC, or even if any “adaptation” was necessary. We find that such a teaching is important in this case to show that the inventors had possession of the claimed invention, given our findings above that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. For completeness, we again reject Patent Owner’s argument that “[t]o show the inventors possessed claim 1 requires no more” than the statement in the written description that “‘the compositions of the present invention are believed to be adaptable . . . with or without system modification.’” PGR12 Resp. 27–28 (quoting Ex. 1001, 7:4–8). Regardless of the exact wording of claim 1, the inventors “still [had to have] describe[d] some way of performing the claimed methods.” Ariad, 598 F.3d at 1355.

    “with regard to claim 17. Nonetheless, we are not persuaded by Petitioner’s contentions. Rather, we find that the ’239 patent contains a sufficient written description of an oral dosage form containing “at least 10% zoledronic acid.” The specification describes a full panoply of zoledronic acid concentrations. Liquid compositions may contain “about 10% (w/v) to about 15% (w/v), about 15% (w/v) to about 20% (w/v), about 20% (w/v) to about 30% (w/v), about 30% (w/v) to about 40% (w/v), or about 40% (w/v) to about 50% (w/v) of zoledronic acid.” Ex. 1003, 10:25–28. Solid dosage forms may contain “at least about 10% (w/w), at least about 20% (w/w) . . .” up to “at least about 80% [w/w]” zoledronic acid. Id. at 10:30–32. Solid dosage forms also are described as containing zoledronic acid in ranges beginning from “about 10% (w/w) to about 30% (w/w), about 10% (w/w) to about 20% (w/w) . . .” all the way up to a range of “about 80% (w/w) to about 90% (w/w).” Id. at 10:32–39. The breadth of zoledronic acid concentration ranges disclosed is more comprehensive than, and therefore distinguishable from, the more limited concentration ranges disclosed in Wertheim (claimed range of “at least 35%” not supported by disclosure of 25% to 60% range disclosed in priority application). In short, we determine that a person of ordinary skill in the art – a medical doctor with experience treating CRPS – would have recognized that the “inventor invented what is claimed” and did not overreach in claiming “at least 10% zoledronic acid” in an orally administered dosage form for treating CRPS.

VeriSign, Inc., 545 F.3d 1359, 1371 (2008). Moreover, “anticipation is not proven by ‘multiple, distinct teachings that the artisan might somehow combine to achieve the claimed invention.’” Microsoft Corp. v. Biscotti, Inc., 878 F.3d 1052, 1069 (Fed.

In this case, we agree with Patent Owner that Petitioner is improperly using claim 1 as a roadmap to cherry pick teachings of the Klecker reference to arrive at compounds encompassed by the genus of that claim. For example, we acknowledge that Klecker teaches that a fluorine may be placed below the ring at the 2' position of the sugar ring. Ex. 1005, 19:25‒26. Petitioner does not point us to any teaching of Klecker, however, that teaches a compound that has both a methyl group and a fluorine at the 2' position of the sugar ring, regardless of whether the fluorine is in the up position or the down position. That is, although the broad genus of compounds disclosed by Klecker encompasses such compounds, Petitioner does not point us to any teaching, other than the broad disclosure of the genus, wherein “W, X, Y, [and] Z” may be “H, hydroxy, halogen, alkyl (C1- C6), alkoxy (C1-C6)a label containing moiety or a label” (Ex. 1005, 15:3‒5), that would direct the ordinary artisan to choose X and W such that one of X and W is methyl and the other is fluorine, much less pointing to support of X as fluorine and W as methyl.” slip op. at 11

  • Expert testimonyPetitioner expert discountedDecided for patent owner

    “Petitioner relies on the Declaration of Dr. Fortunak in asserting that because Klecker teaches the X position may be substituted with fluorine and teaches that W can be an alkyl (C1 – C6), the ordinary artisan would understand from “general knowledge and common sense that methyl is a preferred lower alkyl in that group.” Pet. 34 (citing Ex. 1002 ¶ 92). Dr. Fortunak, however, merely repeats the statement in the Petition without citing any evidentiary support. See Ex. 1002 ¶ 92; see also id. ¶¶ 93‒95 (discussing choosing other substituents in the structure of Klecker). Conclusory statements by an expert “that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” 37 C.F.R. § 42.65(a). Furthermore, Petitioner’s conclusory statements (Pet. 34‒35) that because C is the first substituent identified for J, and H and OH are the first two substituents identified for Y and Z and, thus, the ordinary artisan would immediately envisage a compound where J is C, Y is H, and Z is OH, do not sufficiently persuade us that the ordinary artisan would immediately envisage their implementation to arrive at compounds that fall within the genus of claim 1.” slip op. at 12

    “To the extent that Petitioner (Pet. 51‒52) is invoking inherency in arguing that the express teaching of Sommadossi that R7 may be chloro, 6 Britton et al., U.S. Patent 5,420,266, issued May 30, 1995 (Ex. 1011). bromo and iodo, is also an express teaching that R7 may be fluoro, we disagree that the use of fluoro as the R7 group is inherent in the teachings of Sommadossi. “Inherency . . . 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.” MEHL/Biophile Int’l Corp. v. Milgraum, 192 F.3d 1362, 1365 (Fed. Cir. 1999), quoting In re Oelrich, 666 F.2d 578, 581 (CCPA 1981). Even though the ordinary artisan may have understood that fluoro is also a halogen and may be substituted for chloro, bromo, or iodo, the fact remains that Sommadossi taught the use of, inter alia, chloro, bromo, or iodo at the R7 position, specifically, rather than a halogen element, generally. Ex. 1006, 13:24‒27. Petitioner’s argument (Pet. 52) that “Sommadossi taught that R6 could be ‘chloro, bromo, fluoro, [or] iodo,’” is actually counter to Petitioner’s assertions. That is, that statement demonstrates that Sommadossi knew that “fluoro” could be included in the list of halogens. Moreover, Sommadossi defined the term “halo” as “chloro, bromo, iodo, and fluoro.” Ex. 1006, 52:31. Thus, to avoid inadvertently excluding a halogen, Sommadossi could have used the term “halo” in listing the possible substituents for the R7 group, but chose not to do so. Accordingly, we determine that Petitioner has not sufficiently established that Sommadossi anticipates the compounds of claim 1. Because, as discussed above in our analysis of the anticipation ground over Klecker, all of the claims require the compound of that claim, or a particular compound that falls within the genus of claim 1, Petitioner has also not sufficiently demonstrated that any of the challenged claims are anticipated by Sommadossi. Accordingly, we decline to institute trial as to any of the challenged claims on the basis that the claim is anticipated by Sommadossi.” slip op. at 17

    “A. The Level of Ordinary Skill in the Art Petitioner argues that a person of ordinary skill in the art at the time of the invention would have had a B.S. or M.S. in biochemistry, polymer chemistry, medicinal chemistry, pharmaceutical chemistry, or a related field with “several years” of practical experience. Alternatively, according to Petitioner, the ordinary artisan would have had less practical experience but a Ph.D. in one of those fields, or an M.D. in dermatology, plastic surgery, or a specialty related to the clinical use of dermal fillers. Pet. 10 (citing Ex. 1041 ¶¶ 12–13). Patent Owner does not contest that argument in the Preliminary Response. For purposes of this decision, we accept Petitioner’s definition, which, on this record, is consistent with the level of skill reflected in the asserted prior art references. See Okajima v.

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

    “Second, a term in a patent preamble is limiting when it “breathes life and meaning into the patent claims.” In re Wertheim, 541 F.2d 257, 269 (CCPA 1976). “Whether to treat a preamble as a limitation is a determination ‘resolved only on review of the entire” patent disclosure “to gain an understanding of what the inventors actually invented and intended to encompass by the claim.’” Catalina Mktg. Int’l. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quoting Corning Glass Works v. Sumitomo Electric U.S.A., Inc., 868 F.2d 1251, 1257 (Fed. Cir. 1989)). Our review of the ’475 patent persuades us that the inventors “actually invented and intended to encompass by” claim 1 a stable composition as defined in the specification. Catalina Mktg. Int’l., 289 F.2d at 808. The inventors disclosed and claimed a “stable” composition containing both HA and lidocaine that overcame the “relative inferior stability properties” of prior art compositions. Ex. 1001, 2:6–32. In that regard, the specification repeatedly refers to the ability of the claimed compositions to remain stable after high-temperature sterilization procedures (such as autoclaving) or shelf-storage storage for prolonged lengths of time. See, e.g., id. at 2:42–49 (contrasting the “enhanced stability” of the claimed compositions “relative to conventional HA-based compositions including” “lidocaine” “when subjected to sterilization techniques such as autoclaving” or “when stored for long periods of time at ambient temperature”);” slip op. at 10

  • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed petitioner constructionDecided for petitioner

    “One final point pertaining to the “stable” limitation requires discussion. The specification makes clear that stability, in the context of the ’475 patent, relates to the “shelf life” of the composition “when stored for a lengthy period of time” prior to injection into a patient, for example, “for a period of time of at least 6 months to a year or more.” Id. at 6:51–53, 13:51; see id. at 2:26–27 (objective of invention is to provide “HA-based injectable compositions which incorporate lidocaine” that are not “prone to” degradation “when placed in storage for any significant amount of time”), 4:42–43, 5:33–38 (composition has “enhanced stability” “when stored at ambient temperature for an extended period of time”), 8:4–5 (the composition of the invention will “remain stable when stored for long periods of time at room temperature”). Accordingly, we determine that the preamble term “stable” (Ex. 1001, 16:40) “breathes life and meaning into” claim 1 and, therefore, is limiting. In re Wertheim, 541 F.2d at 269. We adopt for purposes of this decision the following definition of “stable,” which is advanced by Petitioner: soft tissue filler that is free of viable microorganisms as determined by a sterility test recognized by a regulatory authority, the filler can be sterilized by any method known in the art, and is resistant to degradation such that the composition maintains one or more of the following aspects: transparent appearance, pH, extrusion force and/or rheological characteristics, hyaluronic acid (HA) concentration, sterility, osmolarity, and lidocaine concentration, after being effectively sterilized by autoclaving and subsequently stored at a temperature of at least about 25° C for at least about two months. Pet. 11. That construction is not opposed by Patent Owner at this stage of the proceeding (Prelim. Resp. 3–4) and is substantially consistent with an express definition set forth in the specification. Ex. 1001, 5:17–20.” slip op. at 12

    “We find Petitioner’s proposed construction to be more persuasive based on the ’376 patent specification. In particular, the specification defines “unsuitable for injection” “to mean that one would have substantial difficulty injecting the dosage form (e.g., due to pain upon administration or difficulty pushing the dosage form through a syringe) due to the viscosity imparted on the dosage form, thereby reducing the potential for abuse of the opioid analgesic from the dosage form.” Ex. 1001, 3:15–20. Additionally, in an example concerning the formation of a gel at different concentrations, the specification characterizes certain solutions as “THICK (10 cP to 60 cP): Although a syringe can be filled with this solution, it was hard to do.” Id. at 32:8–24, Table 3. Thus, the specification teaches that a viscosity of at least 10 cP is difficult to pull into a syringe or administer parenterally (via injection). Patent Owner does not address these teachings of the specification. We, therefore, determine that the broadest reasonable interpretation of “unsuitable for parenteral administration” and “unsuitable to pull into an insulin syringe” encompasses a gelling agent that imparts a viscosity of at least 10 cP.” slip op. at 10

Abercrombie & Fitch Trading Co., 719 F.3d 1367, 1371 (Fed. Cir. 2013). Collateral estoppel can attach in proceedings before the Office for identical issues that were addressed with respect to a different patent during prior district court litigation.

All four factors for collateral estoppel are met here. With regard to the first factor, the issue of Joshi’s status as prior art is identical for both proceedings. The ’376 patent is part of the same chain of continuity as the ’888 patent, and both patents share the same specification and claim priority to the same non-provisional application filed August 6, 2002 and provisional application filed August 6, 2001.

See Ex. 2091, 5.

Moreover, the draft application was forwarded as part of an email from Patent Owner’s attorney, which “[e]nclosed the latest draft of the tamper resistant application.” Ex. 2091. As such, there is no evidence to suggest that the list of thickening agents included as part of the draft application originated from the inventors as opposed to patent counsel. 11 We recognize that the same broad disclosure with a “laundry list” of possible gelling agents is found in the specification of the ’376 patent. See Federal Circuit has held that such “laundry list” disclosures are insufficient to satisfy the written description requirement when there is no further guidance (“blazemarks”) provided about which species or combination of species included as part of the list may be selected to arrive at the claimed invention. See Fujikawa v. Wattanasin, 93 F.3d 1559, 1571 (Fed. Cir. 1996). Not having specifically named or mentioned the combination in any manner, “one is left to select[] from the myriads of possibilities encompassed by the broad disclosure, with no guide indicating or directing that this particular selection should be made rather than any of the many others which could also be made.” In re Ruschig, 379 F.2d 990, 995 (CCPA 1967); see also Los Angeles Biomedical Research Inst. at Harbor-UCLA Med.

Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991)). Other evidence of record further supports our conclusion that the inventors of the ’376 patent had not conceived of or reduced to practice the claimed formulation prior to Joshi’s August 30, 2001 filing date. In his Declaration, inventor Benjamin Oshlack attests that Patent Owner’s laboratory scientists focused on “testing the syringeability of various concentration solutions of pectin, sodium alginate, and sodium acrylate, as well as combinations of pectin and sodium alginate” between January 4 and Ex. 1001, 6:46–62. We, however, do not address the issue of written description support for any of the subsequently filed applications. 17, 2001. Ex. 2081 ¶ 22. Additionally, Mr. Oshlack attests that the scientists had evaluated “xanthan gum, carrageenan, and locust bean gum (and combinations thereof) as gelling agents, between April 5 and 12, 2001.” Id. ¶ 23. None of the laboratory notebook excerpts proffered by Patent Owner mention a combination of HPMC and PEO as gelling agents to be used in an oxycodone formulation. Exs. 2087–2090. Consistent with the testing actually done, the working examples set forth in the ’534 provisional (as well as in the ’376 patent) focus on xantham gum, pectin, microcrystalline cellulose, and hydroxyethlcellulose as the gelling agents. See Ex. 1026, 44– 49 (Examples 1–5). We find, therefore, that the inventors did not particularly consider either PEO or HPMC, let alone both PEO and HPMC in combination, when evaluating possible gelling agents for an abuse-deterrent formulation of oxycodone. Accordingly, because we find that the ’376 patent is not entitled to a filing date earlier than August 6, 2002, we further determine that Joshi qualifies as § 102(e) prior art as of that date. Having determined that Joshi qualifies as prior art, we turn to the merits of Petitioner’s patentability challenges.” slip op. at 21

The mere fact that a certain thing may result from a given set of circumstances is not sufficient.” MEHL/Biophile Int’l. Corp. v. Milgraum, 192 F.3d 1362, 1365 (Fed. Cir. 1999).” Dec. 14. However, we remain persuaded at this stage of the proceeding on the current factual record based on Hoffbrand 1998 and the Mehta Declaration, that Petitioner established a “reasonable likelihood” that Hoffbrand 1998 necessarily disclosed treatment of patients with “an iron overload condition of the heart” with a therapeutically effective amount of deferiprone. See Dec. 16–20; 35 U.S.C. § 314(a). Patent Owner does not identify a definition of the phrase “iron overload condition of the heart” in the ’328 patent Specification that distinguishes the claimed patient population from Hoffbrand’s disclosure of “10 patients [that] had a liver iron content above 15.0 mg/g dry weight, ie, falling within the range that has been associated with cardiac disease.” Ex. 1007, 297. The reasonable understanding of Hoffbrand’s teaching of this association between liver iron content and cardiac disease is that all ten patients with the elevated iron levels also necessarily fell into the spectrum of having “an iron overload condition of the heart.” Indeed, Patent Owner’s Declarants do not rebut Hoffbrand’s teaching that liver iron content above 15.0 mg/g identifies patients with cardiac disease, and, therefore, with “an iron overload condition of the heart.” Dr. Coates simply notes that Hoffbrand 1998 reports five treated “patients suffered fatal complications. . . . Four of the five reported fatalities resulted from congestive heart failure.” Ex. 2001 ¶ 37. Cf. Pennell Decl. Ex. 2003 ¶ 37. That statement supports the position that Hoffbrand 1998 treated patients who inherently had an ultimately fatal “iron overload condition of the heart” with 75 mg of deferiprone, acknowledged by claim 15 of the ’328 patent as a therapeutically effective amount. Ex. 1007, 295; Ex. 1001, 28:33–37. We recognize that Dr. Pennell stated that “a patient with a liver iron content above 15 mg/g dry weight is at risk of developing cardiac disease not that such liver iron content definitely establishes cardiac disease.” Ex. 2003 ¶¶ 50–51, citing Exhibits 2007, 2015, and 2016. The Exhibits cited by Dr. Pennell do not identify evidence showing a single patient with a liver iron content that exceeds 15.0 mg/g but failed to display an “iron overload condition of the heart.” See Ex. 2003 ¶ 51. Exhibit 2007 states “while whole liver iron levels >15 mg/g dry weight . . . have been shown to predict patients at highest risk of cardiac death, it is not known how these variables relate to cardiac iron deposition.” Ex. 2007, 1. No specific patient data is provided in Exhibit 2007 comparing liver iron levels of particular patients with “iron overload.” See id. Similarly, Exhibits 2015 and 2016 also do not identify any patients with elevated liver iron content >15 mg/g dry weight with normal cardiac iron levels. Therefore, the evidence currently of record in Hoffbrand 1998,” slip op. at 3

    “Regarding the second argument, Dr. Mehta relied upon specific facts within the Olivieri Abstract 1995 itself to support the conclusion that “lower TRT values indicate cardiac disease due to iron overload. Ex. 1010 (Olivieri Abstract 1995).” Ex. 1002 ¶ 75. In particular, Olivieri Abstract 1995 states “MRI demonstrates changes consistent with reduction in cardiac iron in L1 [deferiprone]-treated pts, in who baseline T2 relaxation time (TRT of 23.9±6.4 msec (normal >32) has increased to 32.4±9.3msec.” Ex. 1010. Olivieri Abstract 1995’s identification of the value of “32” as normal for TRT levels with lower values such as “23.9±6.4” as associated with elevated cardiac iron levels that require treatment with deferiprone, provides factual support for Dr. Mehta’s conclusion that patients with these lower TRT values inherently have “an iron overload condition of the heart.” See Ex. 1002 ¶ 75.” slip op. at 6
