    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “The problem we find with this position is that the Petitioner is reading claim elements into the description of these references. Patent Owner points out that the profiles are not being adjusted, but rather being selected from twenty-four previously stored profiles. Resp. 30–31. While the ear module operational profile changes, we observe that this is because it is using a different profile, which was just uploaded from the control unit. The act of moving the finger around on the screen to us perhaps appears to change the profile, when it is in fact moving through a set of preexisting profiles and uploading them to the hearing aid instead, changing operation of the hearing aid itself but not adjusting the profile itself. Michael states: This permits the user to select a hearing profile by simply moving visual indicator 924 over main region 922 while listening to a sound stream broadcast by ear 35 module 10; the sound stream being heard by the user reflects the hearing profile corresponding to the current position of the visual indicator 924 in real-time.

      “Upon review of the parties’ respective definitions of a person of ordinary skill in the art, we adopt Petitioner’s definition as a person with either: (1) a Ph.D. in the field of chemistry, polymer chemistry, chemical engineering, materials science and/or a related field and having at least one year of educational or work experience in the synthesis and development of biocompatible polymer materials; (2) a bachelor’s degree in in [sic] the field of chemistry, polymer chemistry, chemical engineering, materials science and/or a related field and at least two years of work experience in the synthesis and development of biocompatible polymer materials; or (3) any education and experience equivalent to (1) or (2). Pet. 22 (citing Ex. 1003 ¶ 49). We find that Patent Owner’s definition of the ordinarily skilled artisan, i.e., a person having “a Ph.D. degree, or equivalent education, in polymer chemistry, or a bachelor of science degree in chemistry or a closely related field and several years of experience in the development and manufacture of polymer materials for use as tissue sealants,” PO Resp. 15–16 (citing Ex. 2006 ¶ 27), does not differ materially from Petitioner’s definition.

      “1. “visualization agent” In its Petition, Petitioner proposed interpretations of certain claim terms. Pet. 18–22. The Board determined in its Institution Decision, however, that only the term “visualization agent” required express interpretation. Inst. Dec. 8 (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). The Board set forth the broadest reasonable interpretation of “visualization agent” as “an agent that reflects or emits light at a wavelength detectable to a human eye so that a human eye may visualize the hydrogel coating.” Id. at 9. Neither party challenges that interpretation. See, e.g., Third Tr. 6:15–17. We have reassessed that determination in light of the arguments and evidence adduced at trial, and maintain that determination based on the full record.” slip op. at 11

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

      “In general, a preamble limits the invention if it recites essential structure or steps, or if it is necessary to give life, meaning, and vitality to the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quotation omitted). “Conversely, a preamble is not limiting where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Id. Here, we determine that the preamble phrase “suitable to coat a tissue of a patient” is not merely a statement of purpose, but instead represents the “essence or a fundamental characteristic of the claimed invention.” Vizio, Inc. v. Int’l Trade Com’n, 605 F.3d 1330, 1340 (Fed. Cir. 2010). In Vizio, the Federal Circuit held that a preamble reciting “for decoding” certain data “is properly construed as a claim limitation” because the apparatus and method claims reciting that preamble “would have little meaning without the intended objective of decoding.” Id. at 1341. Similarly here, we determine that the method step of claim 1—namely, mixing reactive nucleophilic precursor species, electrophilic precursor species, and a visualization agent—would have little meaning without the intended objective of forming a hydrogel coating on the tissue of a patient. Put differently, there would be no reason to perform the method step of claim 1 but for forming a hydrogel coating on the patient’s tissue. See Ex. 1001, 39:56–40:2 (claim 1) (providing that the reactive precursors crosslink after contact with the tissue to form a hydrogel in the form of a coating). Thus, we determine that “suitable to coat a tissue of a patient” is limiting in this case because it gives “life and meaning” to method claim 1. We further find that the arguments and evidence in this case show that skilled artisans would reasonably interpret “suitable to coat a tissue of a patient” as encompassing a biocompatibility requirement. Although Petitioner correctly notes that “[n]one of challenged claims recite the term ‘biocompatible,” Petitioner acknowledges that skilled artisans understand “that hydrogels are, by their nature as water-swelled materials, known to be biocompatible.” Pet. Suppl. Br. 4–5. Petitioner’s expert, Dr. Lowman, declared that “biocompatibility is presumed as a fundamental aspect of the claimed and disclosed inventions.” Ex. 2018 ¶ 40. And in his deposition, Dr. Lowman testified that skilled artisans would understand “biocompatible” to mean that the hydrogel composition is “suitable for use and tolerated by a patient.” Ex. 2019, 13:2–11 (emphasis added). Thus, we agree with Patent Owner that “suitable to coat a tissue of a patient” reasonably encompasses a biocompatibility requirement for the hydrogel composition. slip op. at 12

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “3. Motivation to combine the prior art references and reasonable expectation of success Even “[i]f all elements of the claims are found in a combination of prior art references,” “the factfinder should further consider whether a person of ordinary skill in the art would [have been] motivated to combine those references, and whether in making that combination, a person of ordinary skill would have [had] a reasonable expectation of success.” Merck & Cie v. Gnosis S.P.A., 808 F.3d 829, 833 (Fed. Cir. 2015). The “motivation to combine” and “reasonable expectation of success” factors are subsidiary requirements for obviousness subsumed within the Graham factors. Pfizer, Inc. v.

      “We are not persuaded that the Board abused its discretion by declining to expressly interpret “nasal spray” and “suitable for nasal administration” in the Institution Decision. As the Board explained in the Institution Decision, Petitioner showed sufficiently for the purpose of institution that the prior art teaches pharmaceutical compositions in the form of nasal sprays.

      “In the Institution Decision, the Board determined that “no claim term requires express interpretation for purposes of this Decision.” Instit. Dec. 7. In its Rehearing Request, Patent Owner argues that the Board “misapprehended or overlooked the importance of construing the terms ‘nasal spray’ and ‘suitable for nasal administration’” found in all the challenged claims. Reh’g Req. 2. In particular, Patent Owner asserts that those terms mean “pharmaceutical formulations that are tolerable to patients, homogeneous, and can be suitably deposited onto the nasal mucosa.” Id. (citing Paper 7, Preliminary Response (“Prelim. Resp.”), 9). Patent Owner alleges that, had the Board construed “nasal spray” and “suitable for nasal administration,” then the Board would have denied the obviousness grounds because “none of the combinations of cited art teach a person of ordinary skill in the art how to make the claimed fixed-dose combination ‘nasal spray’ or formulation ‘suitable for nasal administration’ with a reasonable expectation of success.” Id. at 2–3 (citing Prelim.

      “a “conventional method” that is used for calculating nitrogen needs for a field. Ex. 1001, 1:39–40. Hauwiller’s system is open to a variety of recommendation equations, as Patent Owner’s declarant agrees. See Ex. 1005, 8:36–48, 9:18–21, 9:34–38, 13:30–35, 13:39–45; Ex. 1020, 8:11–16. This openness supports the obviousness of employing within Hauwiller’s system a conventional equation (or certain aspects of a conventional equation) such as the one set forth in the Background of the ’620 patent. Furthermore, while the conventional equation includes several variables, a basic teaching of the equation is that in calculating the fertilizer recommendation, the amount of nitrogen already present should be subtracted from the nitrogen needed to realize the yield goal. See Ex. 1001, 1:39–50. Dr. Johannsen’s testimony that “subtraction of existing nutrients from the nutrient amount was a conventional thing to do particularly because it helps reduce leaching due to over fertilization” is consistent with this understanding of the conventional equation. See Ex. 1008 ¶ 71. We also recognize that the ’620 patent describes the equation as being a conventional approach for calculating nitrogen needs “for a field” rather than for a specific site within the field. Ex. 1001, 1:39–40. But Hauwiller recognizes that “[d]esired yield potential varies depending upon the soil characteristics by location” and, for that reason, describes the desirability of constructing “a yield goal map for creating an application map based upon site specific yield goals.” Ex. 1005, 9:32–41 (emphasis added). Thus, Hauwiller teaches the advantages and desirability of a site-specific approach. We agree with Petitioner that the “subtracting” step would have been accomplished by applying the teachings of the equation in the Background of the ’620 patent to the site-specific approach of Hauwiller. The evidence supports Petitioner’s contentions summarized above, and we agree with Petitioner that all of the features of claims 1 and 20 are disclosed in Hauwiller and the prior art described in the Background of the ’620 patent, and that there is adequate reason to combine the teachings of the prior art. We have considered Patent Owner’s arguments to the contrary, but we do not find them persuasive for the reasons discussed below.” slip op. at 14

      “We have considered Patent Owner’s and Dr. Heiniger’s opposing views. We observe that Dr. Heiniger does not explain adequately the basis of his opinion that, despite the teachings of the prior art, a person of ordinary skill in the art would have “thought that yield data from previous years would not work for that purpose” because a skilled artisan would have viewed yield data as “fundamentally different” from a measure of biomass. See Ex. 2033 ¶ 167. We also do not discern that either Patent Owner or Dr. Heiniger adequately considers that, in view of the teachings of the prior art, one of ordinary skill in the art would have known that “leaf area index” is a known measure of biomass. See Ex. 1001, 1:63–65. In that regard, they do not explain why a skilled artisan would not understand readily that leaf area index constitutes the type of field history data and previous crop information that Hauwiller contemplates as useful in developing a map for a given field. Accordingly, on the record before us, we conclude that Petition has shown where all the features of claims 2 and 21 are found in the prior art, and that there is articulated reasoning why a person of ordinary skill in the art would have combined the teachings of Hauwiller and the Background of the ’620 patent.

Therefore, for the reasons set forth above, we also determine that Petitioner has not shown, by a preponderance of the evidence, that claims 11, 12, and 17, and dependent claim 18, would have been obvious over the combination of Radwanski, Rowan, and Murch. D. Secondary Considerations of Non-obviousness Patent Owner contends that secondary considerations of non- obviousness, including unexpected results, long-felt but unsolved need, and commercial success of the patented product “compel a determination of nonobviousness.” PO Resp. 49; see id. at 49–59. As discussed above, we find that Petitioner has not established that claims 1–22 of the ’639 patent would have been obvious over the combination of Radwanski, Rowan, and Murch. Thus, we need not address Patent Owner’s evidence regarding secondary considerations of non-obviousness.” slip op. at 17

    • Strike new argumentNew argument disregardedDecided for patent owner

      “In our judgment, Petitioner’s arguments and evidence in the Reply are outside the scope of a proper reply because they do more than merely address Patent Owner’s argument that Petitioner did not establish that fabrics made by the combination inherently would have the claimed TPP value; rather, they attempt to provide new evidence that was not set forth clearly in the Petition as to why the fabric resulting from the combination of Radwanski, Rowan, and Murch necessarily would have the claimed TPP values. Because Petitioner waited until the Reply to serve this evidence on Patent Owner, Patent Owner was denied the opportunity to file responsive evidence. Consideration by the Board of the arguments in the Reply and evidence presented in the Horrocks Declaration in support thereof would be unfair to Patent Owner. Petitioner could have presented this argument and evidence with the Petition, and has not contended or offered any evidence to show otherwise. Because Petitioner belatedly presented these new arguments and evidence to make its case that the TPP value is dictated by the structure of the fabric, we decline to consider the portions of the Reply and the Horrocks Declaration on this issue. See Office Trial Practice Guide, 77 Fed. Reg. at 48,767. Patent Owner had a chance to, and in fact did, cross-examine Dr. Horrocks, but had no further briefing opportunity to challenge Petitioner’s evidence. Although Patent Owner did file observations regarding the cross-examination of Dr. Horrocks, such observations are not designed for submitting substantive arguments. See id. at 48,768 (“An observation (or response) is not an opportunity to raise new issues, re-argue issues, or pursue objections.”). Considering the new arguments and evidence at this late stage would not serve the interests of justice. We have, however, reviewed and considered the arguments in the Petition and evidence therein, and are in agreement with Patent Owner that Petitioner has not provided adequate explanation or evidence to support its contention that the claimed TPP values are inherent in the prior art.” slip op. at 14

      “Whenever a ground based on obviousness is involved, the preferred manner of setting out differences is to state “the subject matter of claim x differs from the reference in that (1) …, (2) …., and (n) ….” Vague statements or hints of differences not only burdens the Board, but puts a patent owner at somewhat of a disadvantage with having to guess what any differences a petitioner believes may exit. Reluctance on the part of counsel to “admit” to and identify a difference is hard to understand, given the fact that a difference does not mean the subject matter claimed is non-obvious. Dann v. Johnston, 425 U.S. 219, 230 (1976) (mere existence of differences between the prior art and an invention does not establish the invention’s non-obviousness).4 Campbell appears to differ from the subject matter of claim 1 of the ʼ758 patent in that Campbell does not describe an in situ regeneration.” slip op. at 40

      “4. Discussion While Campbell does not describe in situ regeneration, and assuming arguendo that claim 1 of the ʼ758 patent requires in situ regeneration, in situ regeneration is a well-known technique described by Saito and Stiles. An in situ regeneration in Campbell makes sense because it eliminates a need to discard spent catalyst and permits one skilled in the art to reuse catalytic material. The reuse of catalytic material would have been recognized as significant due to the expense of platinum. Ex. 1056, page 13:20–23. Patent Owner maintains that the catalytic material of Saito and Stiles “is very different from that of the ʼ758 patent.” Paper 29, 4 Petitioner’s failure to clearly identify differences is not consistent with 37 C.F.R. § 42.104(b)(4) and 42.104(b)(5), as well as 35 U.S.C. § 312(a)(3), which require identifying the grounds “with particularity.” The Petition must specify where each element of a challenged claim is found in the prior art patents or printed publications. 37 C.F.R. § 42.104(b)(2). page 29. “There is nothing in either Saito or Stiles to suggest . . . that the regeneration methods of these two references might be succesfully used for regenerating the catalyst/absorber of Campbell.” Id. at page 30.” slip op. at 41

However, in this case, we are unable to credit much, if any, weight, to Patent Owner’s evidence of long-felt need and commercial success. For long-felt need and commercial success to be convincing, there must be a “nexus” between (1) the long-felt need/commercial success and (2) the claimed subject matter. In re Fielder, 471 F.2d 640, 646 (CCPA 1973). Patent Owner’s evidence is bottomed on Patent Owner’s experience with what is referred to as a “SCONOx catalytic absorption system.” Ex. 2006A ¶ 4 (direct Declaration testimony of Thomas Girdlestone). Patent Owner characterizes the claimed method as embodying a SCONOx system. Paper 29, page 37:3–4. According to Mr. Girdlestone, the effectiveness of reducing NOx in a SCONOx system was tested at a turbine facility run at EmeraChem’s then-affiliate Sunlaw Energy in California. Ex. 2006A, ¶ 5.

      “found sulfuric acid described as an alternative for ammonium sulfate. But, then one has to ask: “Where has Petitioner set out to prove that a Gogek Example 3 composition with sulfuric acid used in place of ammonium sulfate meets the limitations of claim 32 as it depends from claim 1?” The relevant testimony is that of Dr. Frederick J. Hirsekorn. Ex. 1005, ¶ 84: Gogek renders the . . . [sulfuric acid] limitation of . . . Claim 32 . . . obvious at least because it discloses that the chemical adjunct may comprise sulfuric acid. Ex. 1003, 1:72–2:4. At the time of the . . . invention of the ’827 Patent, it would have been obvious to a person of ordinary skill in the art to add a small amount of the sulfuric acid as taught in Gogek to the specific formulation of Example 3 of Gogek in order to acid catalyze the inversion of the sucrose in the molasses to produce additional reducing sugars (e.g., dextrose) available for consumption during curing. Producing additional reducing sugar reactants in situ would help ensure that all of the ammonium cations react with the carbonyl group of a reducing sugar, and allow the reaction to run to completion through the consumption of all reactants. Completing the reaction would also improve the quality of the binder. Therefore, one of ordinary skill in the art would have been motivated to use the sulfuric acid expressly disclosed in Gogek with the ammonium sulfate used in the formulation from Example 3 of Gogek in order to achieve these well-known benefits. Agreeing arguendo with Dr. Hirsekorn’s observations, those observations at best prove that one would have found it obvious to use sulfuric acid along with, or possibly in place of, the ammonium sulfate described in Gogek Example 3. But, those observations in no way purport to prove that use of ammonium sulfate with a small amount of sulfuric acid would produce a block having the characteristics of the material of claim 32 as it depends from claim 1. We believe our concern, and that of Patent Owner, is more than theoretical. Gogek indicates a preference for using ammonium sulfate. Ex. 1003, col. 1:72. As is often the case in patent specifications, Gogek does not say why ammonium sulfate is preferred. It is not unreasonable to assume that Gogek had some reason for making the statement. Once Example 3 is replicated with a change that would not be the preferred embodiment, it is not unreasonable to assume that a non-preferred embodiment may have properties differing from those of a block made in accordance with Example 3 without sulfuric acid.

      “The testimony in support of obviousness of the subject matter of claim 27 is that of Dr. Hirsekorn. Ex. 1006, ¶ 105: At the time of the purported invention of the ’089 Patent, it would have been obvious to a person of ordinary skill in the art to add a monoammonium phosphate to the binder composition of Example 3 of Gogek in order to reduce the corrosivity of the binder and preserve . . . manufacturing equipment. In the continuous manufacturing process disclosed in Swift, some manufacturing equipment will be in contact with the solution at all times, amplifying the need to include a corrosion inhibitor to extend the life of the manufacturing equipment. Accordingly, in order to prevent corrosion and “decrease the cost of manufacturing bound materials” (Ex. 1003, ¶ [0073]), it would have been obvious to a person of ordinary skill in the art to add a mono-ammonium phosphate as disclosed in Swift to the binder of Example 3 of Gogek to inhibit corrosion.
