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

    “reconsider the issue of our construction of “bleach powder.” The parties agree that the specification of the ’954 patent does not contain an express definition of “bleach powder,” so we are required to give the term its “ordinary and customary meaning, as would be understood by one of ordinary skill in the art in the context of the entire disclosure.” Translogic, 504 F.3d at 1257; see Pet. 27–28 (arguing that, “[a]bsent any . . . clear intent, the BRI must be consistent with the interpretation that those skilled in the art would reach,” then offering no particular construction of “bleach powder”); Prelim. Resp. 29–30 (“A person of ordinary skill in the art would have understood that bleach powder combines persulfates with alkalinizing compounds . . . in a fine dry particulate form.” (citing only sources outside the ’954 patent)). In arguments that we may consider, the parties draw our attention to six sources of evidence about the ordinary understanding in the art of “bleach powder.” Req. 2–5 (citing Ex. 1039, 48:9–49:9); Prelim. Resp. 29– 30 (citing Ex. 1002, 15:45–65; Ex. 1011, 17; Ex. 2005, 6; Ex. 2007, 3; Ex. 2012 ¶¶ 34–36). There is evidence that supports Patent Owner’s view that the ordinary meaning of “bleach powder” is a powder that contains an alkalizing agent in addition to persulfates, as opposed to merely a persulfate powder. A textbook called “Hair Preparations” by Thomas Clausen and others states that, at least in paste bleaches, “a bleach powder” is used that “consists of a peroxodisulfate, an alkalinizing agent,” and other ingredients. Ex. 1011, 17. In the context of cream and gel bleaches, this reference teaches that “[p]eroxosulfate . . . can be added as a bleaching powder” but is silent about whether the “bleaching powder” contains any additional ingredients. Id. In a book chapter on “Hair Coloring” by Keith C. Brown, a “bleach booster” powder is discussed that “is usually a mixture of ammonium and potassium persulfates” and that has “metasilicates mixed in with the persulfates” to provide “[a]lkaline pH.” Ex. 2005, 6. Against this evidence is the testimony of Dr. Borish that “powder lighteners” or “bleach powders” include “persulfate salts.” Ex. 1039, 48:9–49:9. But Dr. Borish does not state affirmatively that the persulfate salt is all that is required for a powder to be a bleach powder, only that a persulfate salt is a necessary component of a bleach powder. Id. Accordingly, his testimony does not outweigh the evidence that, to a person of ordinary skill in the art, a bleach powder contains both a persulfate salt and an alkalizing agent. We are not persuaded, therefore, that we abused our discretion by construing “bleach powder” to require both of those components.” slip op. at 6

Following the summary of those prior art teachings, Dr. Thirman asserts “[t]hus, the alleged unexpected properties would have been expected” (Ex. 1002 ¶ 110), but provides no further evidentiary support for the proposition that the results obtained by treating relapsed and/or refractory MCL with lenalidomide would have been expected. Again, during prosecution, the Examiner maintained that the combined prior art (Zeldis, Damaj, Wilson, and Kaufmann) would have given one of ordinary skill in the art a reason to use lenalidomide to treat patients with relapsed and/or refractory mantle cell lymphoma, but concluded that the evidence of obviousness was outweighed by Applicant’s evidence of unexpected results—namely, a 28% overall response rate in patients with relapsed and/or refractory mantle cell lymphoma. Although Drach—given its particular focus on treating mantle cell lymphoma—is stronger evidence than Damaj, Wilson, and Kaufmann that one of ordinary skill in the art would have had a reason to treat MCL patients with lenalidomide, Drach is no more informative as to expected results than the references the Examiner relied on in making out a prima facie case of obviousness, i.e., Damaj, Wilson, and Kaufmann. Essentially, Petitioner and Dr. Thirman disagree with the Examiner’s conclusion that, on balance, the subject matter of the challenged claims would not have been obvious, in light of the level of response in patients 25 with relapsed and/or refractory MCL (as described in Dr. Zhang’s Declaration and the underlying Goy reference), despite one of ordinary skill in the art having had a reason to administer lenalidomide to treat MCL.” slip op. at 25

    “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.

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.

    “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.

    “Although the statements above encompass “mixtures” of HPMC and PEO among a myriad of other possibilities for the gelling agent, we find no basis to conclude that the inventors of the ’376 patent were in possession of the specifically claimed formulation from such a broad disclosure.11 The 10 The April 25th draft application is heavily redacted and we thus cannot discern what other materials were specifically contemplated as “thickening agents” by that time. See Ex. 2091, 5. However, given the nature and amount of the redactions and Patent Owner’s assertion that the draft application ultimately led to the filing of the ’534 provisional with the broad disclosure set forth above, we find it reasonable to conclude that additional materials were included in the draft application. 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. Ctr. v. Eli Lilly & Co., 849 F.3d 1049, 1057 (Fed. Cir. 2017) (“To satisfy the written description requirement, the disclosure in each application must ‘reasonably convey[ ]’ to those skilled in the art that as of the claimed priority date the inventor was in possession of the later claimed subject matter.”) (citing Vas-Cath Inc. v. 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.

Patent Owner agrees with Petitioner’s proposed level of skill in the art. PO Resp. 27. We, therefore, apply that skill level in our analysis, with the understanding that the level of skill of art in this proceeding is also reflected in the prior art of record. See Okajima v.

    “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.” Id. at 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 10cp 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 9

Cir. 1994) (citing Lawlor v. National Screen Serv. Corp., 349 U.S. 322, 326 (1955)). The Federal Circuit has articulated a four-factor test in determining whether collateral estoppel attaches: “(1) the identity of the issues in a prior proceeding; (2) the issues were actually litigated; (3) the determination of the issues was necessary to the resulting judgment; and (4) the party defending against preclusion had a full and fair opportunity to litigate the issues.” Levi Strauss & Co. v.

  • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateDecided for petitioner

    “Although the statements above encompass “mixtures” of HPMC and PEO among a myriad of other possibilities for the gelling agent, we find no basis to conclude that the inventors of the ’376 patent were in possession of the specifically claimed formulation from such a broad disclosure.10 The 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 9 The April 25th draft application is heavily redacted and we thus cannot discern what other materials were specifically contemplated as “thickening” agents by that time. See Ex. 2091, 5. Given the nature and amount of the redactions and Patent Owner’s assertion that the draft application ultimately led to the filing of the ’534 provisional with the broad disclosure set forth above, we find it reasonable to conclude that additional materials were included in the draft application. 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. 10 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 Ex. 1001, 6:46–62. We, however, do not address the issue of written description support for any of the subsequently filed applications. 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. Ctr. v. Eli Lilly & Co., 849 F.3d 1049, 1057 (Fed. Cir. 2017) (“To satisfy the written description requirement, the disclosure in each application must ‘reasonably convey[ ]’ to those skilled in the art that as of the claimed priority date the inventor was in possession of the later claimed subject matter.”) (citing Vas-Cath Inc. v. 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 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.

    “Regarding the interpretation of O’Donnell’s Synacthen test, we do not agree with Patent Owner that the results “lack any significance.” See PO Resp. 20. We are persuaded that one of ordinary skill in the art would understand the results of this test to be an indicator that something was amiss with the O’Donnell Study C patients’ cortisol levels following administration of abiraterone acetate. Results of the Synacthen test led O’Donnell to conclude that further studies were needed to determine whether glucocorticoid replacement would be necessary. Ex. 1003, 2323. We understand Patent Owner’s position that the “Synacthen test results in O’Donnell do not give a complete picture of a patient’s glucocorticoid production.” PO Resp. 21. We, however, do not perceive that a complete picture of a patient’s glucocorticoid production is required for one of ordinary skill in the art to be motivated to explore whether glucocorticoid replacement therapy was necessary. Petitioner’s experts opine that O’Donnell’s results for the Study C patients were “unquestionably abnormal” and implied that abiraterone acetate could result in chronic cortisol deficiency “for which glucocorticoid replacement therapy could be required.” Reply 6– 7 (citing Ex. 1093, 22, 68; Ex. 1023, 1245). We credit this testimony as supporting Petitioner’s argument that one of ordinary skill in the art, upon reviewing O’Donnell’s Synacthen test results and statement regarding impact on adrenal reserve, would not conclude that they lack any significance; rather, they would conclude that they are significant enough to merit further investigation of administration of abiraterone acetate with glucocorticoids.” slip op. at 19

See, e.g., Tr. 14:20–15:5; Ex. 1003, 2318, Figure 1; Ex. 1188, 168:22–169:23. Both O’Donnell and Barrie refer to ketoconazole in their discussions of abiraterone acetate, indicating that teachings regarding ketoconazole administration were a starting point for exploration of abiraterone acetate administration. Ex. 1003, 2318; Ex. 1005, Table 1. For example, O’Donnell, after evaluating ketoconazole as an agent, turns to an evaluation of abiraterone acetate as a more selective CYP17 inhibitor, i.e., as an improvement on ketoconazole. Ex. 1003, 2318. After presenting the results from its studies, O’Donnell discusses that, in the clinical use of ketoconazole, “it is common practice to administer supplementary hydrocortisone” and that, therefore, “further studies with abiraterone acetate will be required to ascertain if concomitant therapy with glucocorticoid is required on a continuous basis, at times of physiological stress, if patients become symptomatic or indeed at all.” Id. at 2323. This statement represents the proposition that one of ordinary skill in the art would use the example of ketoconazole’s clinical use to take the next investigative steps with abiraterone acetate. We have not been presented with evidence that dissuades us from taking this statement at face value. Patent Owner’s expert testified that ketoconazole, as “an inhibitor of steroid biosynthesis that had been used at that point,” was a basis for comparison: “When you write scientific papers, you always like to make comparisons with what is known and explain why your results are different or the same or what the caveats are. And I think that’s setting up . . . to understand what comes next, why they did this experiment.” Ex. 1188, 169:15–23. Thus, we are persuaded that one of ordinary skill in the art would understand that both ketoconazole and abiraterone are CYP17 inhibitors, albeit with different mechanisms. With this knowledge, and given the teachings of the prior art on administration of ketoconazole and administration of abiraterone acetate, we find that one of ordinary skill in the art would look to the administration of ketoconazole for guidance on how to administer abiraterone acetate.” slip op. at 17

    “Regarding Patent Owner’s comparison of abiraterone acetate monotherapy with abiraterone acetate/dexamethasone therapy, we agree with Petitioner that “to the extent that [Patent Owner] tries to draw any conclusion between studies that involve a combination with dexamethasone, we respectfully submit that there’s no nexus there” in that “[d]examethasone is not what’s claimed and there’s no nexus to the claims.” Tr. 19:17–20, 20:2– 3. Although dexamethasone and prednisone are both glucocorticoids, Patent Owner does not point us to satisfactory evidence as to why the ordinary artisan would consider dexamethasone and prednisone to be interchangeable for the purpose of comparing results. Cf. Ex. 2038 ¶ 240 (stating that a person of ordinary skill would “understand the dexamethasone extension study results to be due to a class effect of glucocorticoids” without further citation). Because the claims cover prednisone, and not any other glucocorticoid, the results of the combination of dexamethasone with abiraterone acetate are of limited use, as we are not informed of the similarities or differences of the mechanism of action of those glucocorticoids or how the mechanism leads to the asserted unexpected results. Moreover, to the extent the table purportedly compares the abiraterone acetate monotherapy to abiraterone acetate administered with prednisone, the table compares the abiraterone acetate monotherapy administered in clinical trial COU-AA-001 with the abiraterone acetate administered with prednisone in clinical trial COU-AA-002, without explaining or accounting for the differences between the two trials. Tr. 20:10–19. We determine that there is insufficient evidence that the alleged unpredictable and unexpected results of abiraterone acetate and prednisone are objective indicia of nonobviousness of the challenged claims. Patent Owner does not sufficiently tie the allegedly unpredictable and unexpected result to the administration of abiraterone acetate and prednisone as claimed.

Thus, we are persuaded that one of ordinary skill in the art would understand that both ketoconazole and abiraterone are CYP17 inhibitors, albeit with different mechanisms. With this knowledge, and given the teachings of the prior art on administration of ketoconazole and administration of abiraterone acetate, we find that one of ordinary skill in the art would look to the administration of ketoconazole for guidance on how to administer abiraterone acetate.” slip op. at 18
