    “Patent Owner contends that claim construction is necessary for the “seed-applied substance” term because Petitioner allegedly ignores the teaching of the specification in evaluating the term. Prelim. Resp. 12. Patent Owner points to the specification, which defines a “seed-applied substance” as “includ[ing] any composition applied to seeds prior to the seeds being planted (e.g., when the seed comes in contact with the soil in a field).” Id. at 13 (quoting Ex. 1001, 7:45-48). Patent Owner contends that the term means “a substance that is applied directly to the seed before the seed comes into contact with the soil in a field.” Id. (citing Ex. 2001, ¶ 55). According to Patent Owner, Petitioner erroneously uses a definition that “allows the ‘seedapplied substance’ to be applied to the seed (and soil) as the seed lay planted in the soil.’” Id. For the purpose of addressing Petitioner’s grounds, we use the definition of “seed-applied substance” provided in the ’027 patent, i.e., “any composition applied to seeds prior to the seeds being planted (e.g., when the seed comes in contact with the soil in a field).” Vitronics Corp. v.

    “On the current record, we do not find that the disclosure of the ’011 provisional application is sufficient to provide written description support for the limitation of “substantially prevent[ing] forward flow.” The ’253 13 patent defines forward flow as “an amount of liquid in the lumen . . . that exits the distal end . . . in the distal direction” and “is defined as greater than 6 microliters of fluid.” Ex. 1001, 38:18–22. While Patent Owner points to disclosure from the ’011 provisional application which describes “a minimal amount of momentum transfer from the fluid column to the stuck clot to unstick the clot sufficiently” and “[t]he exiting movement of fluid [being] limited to a specific volume and/or pressure and is automatically and precisely controlled” to prevent the “possibility of overshooting,” it would not necessarily be apparent to one of ordinary skill in the art that such disclosure is referring to no greater than 6 microliters of fluid.

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Patents / published applications (effective date, provisional support)Reference is prior artDecided for petitioner

    “Next, we note that Patent Owner does not appear to contest that Teigen gets priority back to the December 12, 2018, filing date of the ’708 provisional application. See e.g., Prelim. Resp. 25. As discussed above, because we find on the current record that the ’253 patent is only entitled to a priority date of July 18, 2019, Teigen is 35 U.S.C. §§ 102(a)(2) and (d)(2) art to the ’253 patent regardless of whether it can receive priority to the ’804 provisional application. However, we discuss the priority date of Teigen here in order to provide guidance to the parties. The ’804 provisional application discloses pulsated aspiration in which, at times, the valve to the vacuum pump is closed and the valve to the saline injection unit is open in order to more efficiently digest a clot that is 25 large or otherwise difficult to aspirate. Ex. 1008 ¶¶ 65, 69. According to the ’804 provisional, “[s]aline pulsated aspirations provide a ‘dynamic’ aspiration force” because “[i]nstead of aspirating clots with a static (constant) vacuum force, pulsated aspiration introduces an acceleration component to the mass transfer force which can help break up larger clots so that they can better fit in the catheter lumen.” Id. ¶ 64. We agree with Patent Owner that the ’804 provisional does not specifically mention “positive pressure.” We also understand, based on the current record, that a positive pressure could result at the distal end of the catheter when the vacuum pump is turned off and the saline injection unit is open to create an influx of saline into the catheter. However, we acknowledge Patent Owner and Dr. Finol’s contentions that such positive pressure is not necessarily inherent because catheters are somewhat compliant and there are many factors that influence the magnitude of a pressure pulse caused by introducing saline into the catheter. We also acknowledge their argument that such an ambient saline flow may not inherently produce a positive pressure sufficient to overcome the mean arterial pressure. These issues will be better resolved on a complete trial record. But, for the reasons stated above and based on the present record, we treat Teigen as prior art for purposes of this Decision.” slip op. at 25

    “We agree with Patent Owner’s proposed construction, as it is most consistent with the intrinsic evidence. The claim language makes clear that “Polymorph A” is “characterized by” the specific peaks set forth in the claims. Ex. 1101, claims 1, 8, 16. Thus, regardless of the alleged conventional definition of a “polymorph,” urged by Petitioner, the inventors are entitled to act as their own lexicographers to define “Polymorph A” according to the recited peaks on the XRPD diffractogram. See Honeywell Int’l, Inc. v. Universal Avionics Sys. Corp., 493 F.3d 1358, 1361 (Fed. Cir. 2007) (“When a patentee defines a claim term, the patentee’s definition governs, even if it is contrary to the conventional meaning of the term.”). That the Specification consistently refers to “Polymorph A” as a proper noun and describes Polymorph A as “characterized by” the recited peaks in an XRPD diffractogram further highlights the inventors’ clear intent to act as their own lexicographer. See, e.g., Ex. 1101, 4:4–5:36; Merck & Co. v. Teva Pharms. USA, 395 F.3d 1364, 1370 (Fed.

During prosecution of the parent ’257 patent application, the examiner rejected original claim 1 as indefinite because it did not define “Polymorph A,” and required one to “refer to the specification to determine what is Polymorph A.” Ex. 2133, 7. Patent Owner then amended the claims to define Polymorph A by adding the specific XRPD peaks recited in claim 1. Ex. 2134, 2; see also id. at 6.

    “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

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. Accordingly, because we find that the ’376 patent is not entitled to a” slip op. at 22
