“In our Institution Decision, we adopted Petitioner’s definition of a person of ordinary skill in the art (“POSITA”) as it was undisputed at the time and consistent with the evidence of record. Inst. Dec. 7–8. Based on our consideration of the full record, we maintain our determination that a POSITA at the time the application for the ’802 patent was filed “would have had at least an undergraduate degree in pharmacy, chemistry, biochemistry, biomedical engineering or a closely related field, such that the POSITA generally understand[s] pharmaceutical formulation.” Pet. 12. Additionally, we agree with Petitioner that “[a] POSITA would be familiar with the chemical ingredients in the [’802] Patent, biocidic agents, and cationic agents, have knowledge of airborne particles including viruses and bacteria, and understand electrostatic fields, electrostatic attraction and repulsion, adhesion and cohesion.” Id.

“of independent claims 1, 2, and 8 as limiting. Inst. Dec. 7–8. The parties do not dispute our construction of the preambles of claims 1, 2, and 8 as limiting. See generally PO Resp.; Pet. Reply 2–4. After consideration of the full trial record, we maintain our construction of the preamble of claims 1, 2, and 8 as limiting for the reasons set forth in our Institution Decision. Id. Briefly, the preamble of independent claims 1, 2, and 8 limits the challenged claims as both the preamble and the body are used to define the subject matter claimed. See Allen Engineering Corp., v. Bartell Industries, Inc., 299 F.3d 1336, 1346 (Fed. Cir. 2002). In particular, the preamble is “necessary to give life, meaning and vitality” to the claim, see id., because it provides the only description in the claim for the application site of the formulation, i.e., “to skin or tissue of nasal passages,” and how the formulation is applied, i.e., “in a thin film.”” slip op. at 8
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownDecided for petitioner
“After consideration of the full trial record, we maintain our construction. From our perspective, the claims themselves support this construction as the claims expand upon the term “electrostatically inhibiting” with specific means for achieving such inhibition. Specifically, claims 1 and 2 recite electrostatically attracting the particulate matter, holding the matter in place, and inactivating the matter. Additionally, the Specification supports our construction as it describes the use of “an electrostatic field such that oppositely charged airborne particulates (including microorganisms) in the vicinity of the surface are electrostatically trapped, held thereto and one or more of the microorganisms so captured is neutralized, killed, inactivated, and rendered harmless.” Ex. 1001, 3:36–40; PO Resp. 10 n.6.” slip op. at 9
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for petitioner
“We adopt the parties’ construction of “adequate impermeability” that has been accepted in the related district court litigation: “Adequate impermeability” refers to the “thin film holding harmful particles in place and inhibiting them from penetrating the thin film and contacting the skin or tissue of an individual’s nasal passages. This is done by varying the concentration of ingredients . . .[,] thereby adjusting the adhesion and cohesion of the thin film.” Pet. Reply 3 (quoting Ex. 1010, 17). Furthermore, as stated in our Institution Decision, along with that term, the claim language explains that the thin film is meant to stick to the skin or tissue and to hold the particulate matter in place. Inst. Dec. 9–10. The claim language also explains that the cohesion of the formulation is adjusted to provide adequate impermeability to the thin film. Thus, it is reasonable to consider the recited impermeability is a function of the cohesive properties of the thin film, and that such impermeability refers to a property of the thin film, i.e., inhibiting the penetration or passage of matter through it onto the skin or tissue at the application site.” slip op. at 10

Fintiv, Inc., IPR2020-00019, Paper 11 (PTAB Mar. 20, 2020) (precedential), the Board set forth six non-exclusive factors for determining “whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” Id. at 6. These factors are as follows: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits.

“The Director set forth in the Interim Procedure that “the PTAB will not discretionarily deny institution of an IPR or PGR in view of parallel district court litigation where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.” Interim Procedure, 7, 9.

“III. WHETHER REHEARING IS WARRANTED Petitioner argues that we misconstrued the claims “as requiring one to add tags in a way that can provide a distinction based on a ‘polynucleotide sequence.’” Req. 6 (quoting Dec. 14 (Petitioner’s emphasis)). Petitioner is correct. More specifically, we implicitly construed the claim language reciting “a second tag sequence distinguishing said sample polynucleotide from other sample polynucleotides from said cell,” as requiring said “distinguishing” to be based on the sequences of the sample polynucleotides. See, e.g., Dec. 14 (“[E]ach strand of cDNA that is tagged in Linnarsson is tagged regardless of the polynucleotide sequence of the cDNA or its corresponding mRNA. Thus, Linnarsson’s tags do not distinguish between ‘sample polynucleotides,’ whether cDNA or mRNA, of different sequences.”). Based on that misunderstanding, we erroneously determined that the proposed modification could not achieve the claim language, stating the following: Petitioner’s proposal appears to defeat satisfaction of another portion of claim 1, namely a “second tag sequence distinguishing said sample polynucleotide from other sample polynucleotides from said cell.” Ex. 1001, 30:62–64. For if the second tag is “added to the CDS or TSO after extension,” as opposed to the sample polynucleotide, as Petitioner argues (Pet. 39 (emphasis added)), it would appear that the second tag would be incapable of distinguishing any sample polynucleotide from other sample polynucleotides. Rather, the second tag would be ligated to each and every extension product bearing a CDS or TSO without regard to the sequence of any sample polynucleotide. Dec. 16. We now reconsider whether to institute.” slip op. at 2

Advanced Bionics Part Two Patent Owner argues that the Petition “fails to show any error in the Examiner’s application during prosecution of the prior art teachings Petitioner now purports to invoke from . . . McCloskey.” Prelim Resp. 23; see also id. at 24–25 (“Revisiting the same art and arguments already overcome during prosecution is a waste of the Board’s limited resources and would unfairly burden PO.”). However, Petitioner argued that “the Examiner committed major error in Examination by erroneously stating that the prior art fails to teach a dual tagging approach when, in fact, this approach is plainly taught in both McCloskey and McCloskey II.” Pet. 67. The record supports Petitioner’s position, and we agree that the error was material to patentability. See Ex. 1005, 131 (Notice of Allowance).

Cir. 2023)). As Sanofi- Aventis holds, a petitioner bears the burden of persuasion to establish that an asserted prior art reference is analogous art to the claimed invention. See Sanofi-Aventis, 66 F.4th at 1377 (“We agree with [the patent owner] that [the petitioner] did not carry its burden to argue that de Gennes is analogous to the [challenged] patent.”); id.

However, the Petition should not be denied for failing to state explicitly that the cited prior art references are analogous art to the ’013 patent. Rather, as Sanofi-Aventis further held: “A petitioner is not required to anticipate and raise analogous art arguments in its petition; instead a petitioner can use its reply to ‘respond to arguments raised in the corresponding opposition, patent owner preliminary response, patent owner response, or decision on institution.’” Sanofi-Aventis, 66 F.4th at 1379 (quoting 37 C.F.R. § 42.23).
