“The Board has recently clarified that “[s]imply noting that the petitioner is adopting a patent owner’s claim construction proposals from district court . . . is not a sufficient reason for advancing different positions in the two forums.” Revvo Techs., Inc. v. Cerebrum Sensor Techs, Inc., IPR2025-00632, Paper 20, 5 (PTAB Nov. 3, 2025) (precedential). In Revvo, as in this case, the petitioner did not propose its own constructions for claim terms in the Petition, but instead accepted the patent owner’s proposed constructions from the related district court litigation. Id. at 2. Although the petitioner had proposed different constructions for the claim terms in district court, it did not explain why it was taking a different position before the Board. Id. The Board’s trial rules “do not necessarily prohibit petitioners from taking inconsistent claim construction positions before the Board and a explain why alternative positions are warranted.” Revvo, Paper 20, 3–4 (quoting Cambridge Mobile Telematics, Inc. v. Sfara, Inc., IPR2024-00952, Paper 12 at 8–9 (PTAB Dec. 13, 2024) (informative)). Petitioner has not sufficiently done so here. Moreover, the fact that Petitioner cannot raise its indefiniteness challenge in an inter partes review is not a sufficient reason to allow Petitioner to take inconsistent claim construction positions before the Board and the district court. Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025- 00340, Paper 18, 3 (Nov. 5, 2025) (informative). As explained in the Board’s Tesla decision: Petitioner’s statement that it cannot raise indefiniteness challenges in an inter partes review is not a sufficient explanation. Indeed, the statement amounts to an assertion that a petitioner should be permitted to raise inconsistent invalidity challenges in the two forums. Petitioner’s explanation may have risen to a sufficient level, for example, if Petitioner had shown that, notwithstanding the alleged indefiniteness of the claim term, an ordinarily skilled artisan would understand that the asserted art satisfies the claim limitation (such as if the limitation prescribed a range and only the outer bounds of the range were unclear). Instead, Petitioner argued indefiniteness in the district court and then adopted Patent Owner’s plain and ordinary meaning construction from the district court litigation in its Petition.

“support a construction that is similar to Petitioner’s construction of a “network path” as “a link between two machines.” See Pet. 17. That is, limitation 1(a) recites “selecting a reachable resource having a network path to access the reachable resource, wherein the reachable resource is a cloud object . . . having access to an external network which is external to the cloud computing environment,” and limitation 1(b) recites “actively inspecting the network path to determine if the network path of the reachable resource is accessible from the external network.” This plain language shows that a network path is simply a connection (link) between an external network object and a resource in a cloud (or cloud object). The specification provides an example of accessing “port 22”: “Active inspection allows to [sic] generate instructions directed at the reachable resource over a network path, which when received by the reachable resource cause the reachable resource to send a response.” Ex. 1001, 5:40–45. The specification also states that “a network path may include sequential representations of possible data/control flows between two or more objects in a graph.” Ex. 1001, 12:49–52; accord Ex. 1001, 12:60–62 (describing “a path show[ing] a connection between security objects and/or computing objects that communicate over a network”), 12:42–44 (“A network path is a connection of two or more security objects accessible from an external or internal network, and/or an external or internal object.”). In other words, the specification indicates that a transmitting testing object may be an object external to the cloud connected via a network path to another object (a cloud resource for testing). The “network path” may also include resources/objects (represented as graph vertices) on the path. See id. at 12:51–59 (“A path may be a vertexonly path, describing a sequence of vertex-to-vertex ‘hops,’ an edge-only path, describing only the edges included in the sequence without description of the associated vertices, or a combined edge-vertex path, describing both edges and vertexes included in the sequence.” (emphasis added)). Accordingly, for purposes of institution, we construe a “network path” as “a connection between an external object and a cloud resource, wherein the connection itself include objects and/or cloud resources.”” slip op. at 9

“proposed combination of Leaning and Gamble teaches all limitations of claims 2 and 9. I find that the added analysis for these claims based on Gamble overcomes the deficiencies in the other ground, including those of the base claim from which they depend. I also differ from my colleagues in how I view secondary considerations of nonobviousness. I find that the developed record of this case does not support that multiple TCP connections or multiple, parallel/simultaneous TCP connections are critical, unclaimed features of the ’772 patent. Indeed, Petitioner does not argue as much, and all challenged claims at least recite multiple TCP connections. Notwithstanding, I would reach the same conclusion as my colleagues that Patent Owner is not entitled to a presumption of nexus. I am persuaded by Petitioner’s argument (Pet. Reply 21–22) that Patent Owner cannot credibly maintain that it is entitled to a presumption of nexus to the same products— the MOVE Media Player and “Sling TV”—across nine patents and 120 claims having different scope while citing to substantially the same alleged evidence of secondary considerations. The MOVE Media Player and “Sling TV” cannot be coextensive with the challenged claims here under these circumstances. In addition, Patent Owner’s own cited evidence suggests that MOVE’s plug-in is a “key” feature of its technology, particularly to ensure “fluidity of playback” (PO Resp. 51–52 (quoting Ex. 2048) (emphasis omitted)), but the claims do not recite a plug-in. This also undermines Patent Owner’s assertions of coextensiveness for claims that all recite “continuous playback.” Otherwise, I agree with my colleagues’ finding that Patent Owner has not adduced significant evidence of direct nexus. Accordingly, I join in my colleagues’ finding that Patent Owner has failed to establish a nexus between the asserted evidence of secondary considerations and the challenged claims. I also agree that Patent Owner’s evidence of secondary considerations is entitled to insignificant weight, or little to no weight, and that it does not outweigh Petitioner’s persuasive obviousness showing under the other Graham factors.

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

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).

Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks.

We, thus, have authority, acting on the designation of the Director, to determine whether to institute an inter partes review under 35 U.S.C. § 314(a). See 37 C.F.R § 42.4(a) (2024) (“The Board institutes the trial on behalf of the Director.”). Under 35 U.S.C. § 314(a), an inter partes review may not be instituted unless the information presented in the Petition shows “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Considering the Petition, the Preliminary Response, and all supporting evidence, we conclude that the information presented in the Petition establishes a reasonable likelihood that Petitioner would prevail in its challenge of at least one claim of the ’621 patent as unpatentable. Pursuant to 35 U.S.C. § 314, we hereby institute an inter partes review of all challenged claims of the ’621 patent on the grounds stated in the Petition.” slip op. at 2
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner, supported by Dr. Bajaj’s testimony (Ex. 1003 ¶¶ 24–27) submits that a person of ordinary skill in the art “would have been someone knowledgeable of and familiar with computer cluster systems and cluster computing techniques” in June 2006. Pet. 12. According to Petitioner, a person of ordinary skill in the art would have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent training, and approximately two years of experience working in the field of cluster computing or parallel processing and would be knowledgeable regarding high-level scientific computing languages. Additional work experience can substitute for specific educational background, and vice versa. Id. (citing Ex. 1003 ¶¶ 24–27). Patent Owner does not address Petitioner’s proposed level of ordinary skill in the art. See generally Prelim. Resp. For the purposes of this Decision, we adopt Petitioner’s undisputed level of ordinary skill in the art because it appears consistent with the problems address in the ’621 patent and the cited prior art.

- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner
“6. Printed Publication Status of Petitioner’s Asserted Prior Art The Federal Circuit instructs that “[t]o qualify as a printed publication, a reference ‘must have been sufficiently accessible to the public interested in the art.’” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1348 (Fed. Cir. 2016) (citing In re Cronyn, 890 F. 3d 1158, 1160 (Fed. Cir. 1989)). “A reference will be considered publicly accessible if it was ‘disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art exercising reasonable diligence, can locate it.” Id. (citing Kyocera Wireless Corp. v. Int’l Trade Comm’n, 545 F. 3d 1340, 1350 (Fed. Cir. 2008)). Further, the question of whether a document qualifies as a “printed publication” for the purposes of 35 U.S.C. § 102 “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to a member of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018) (citing In re Klopfenstein, 380 F.3d 1345, 1350 (Fed. Cir. 2004)). At this stage of the proceeding, Petitioner “must identify, with particularity, evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent and therefore that there is a reasonable likelihood that it qualifies as a printed publication.” Hulu, LLC v. Sound View Innovations, LLC, IPR2018- 01039, Paper 29, 13 (PTAB Dec. 20, 2019) (precedential). The reasonable likelihood standard “is lower than the ‘preponderance’ standard to prevail in in a final written decision.” Id.” slip op. at 16

“We have authority to determine whether to institute a post-grant review under 35 U.S.C. § 324. Institution of a post-grant review is authorized by statute when “the information presented in the petition . . . would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a). Applying that standard on behalf of the Director (37 C.F.R. § 42.4(a)) and in consideration of the Petition and the cited evidence of record, we determine that the information presented shows that it is more likely than not that Petitioner would prevail in establishing unpatentability of claims 1–3 and 5– 15 of the ’773 patent, and therefore, we grant post-grant review for the reasons articulated below.” slip op. at 2

“Petitioner’s proposal is sufficiently comprehensive to encompass the level of skill reflected in prior art relevant to the ’773 patent. It is reasonably clear that, in indicating that a POSA would have an advanced degree (like a Pet. 7. We have adjusted the claims challenged to only those that remain in effect following Patent Owner’s disclaimer. See Ex. 2003. 3 US 7,767,429 B2, issued Aug. 3, 2010 (the “’429 patent”; Ex. 1005). 4 Chao et al., Structure of Human Hyaluronidase-1, a Hyaluronan Hydrolyzing Enzyme Involved in Tumor Growth and Angiogenesis, 46 Biochemistry 6911–6920 (2007) (Ex. 1006). Ph.D.) and years of experience in analysis of protein structure, Petitioner is asserting that knowledge of proteins generally is sufficient to understand the types of problems encountered in the art and the prior art solutions to those problems, and the ordinary artisan need not have expertise specifically in hyaluronidases. See Pet. 16–17. Petitioner requires that the POSA would be able to apply key scientific concepts (e.g., biochemistry, recombinant biology, sequence analysis and protein modeling) to enzymes such as hyaluronidases. See id. At this stage of the proceeding and on the record before us now, we apply Petitioner’s proposed POSA level, which appears consistent with the level of skill shown in the prior art references of record. See Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007).” slip op. at 8
- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for petitioner
“refers to a PH20 polypeptide that contains at least one amino acid modification, such as at least one amino acid replacement as described herein, in its sequence of amino acids compared to a reference unmodified PH20 polypeptide. A modified PH20 polypeptide can have up to 150 amino acid replacements, so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity. Typically, a modified PH20 polypeptide contains 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 amino acid replacements. It is understood that a modified PH20 polypeptide also can include any one or more other modifications, in addition to at least one amino acid replacement as described herein. Id. at 47:8–22 (emphasis added). On this record, however, we find that the definition of “modified PH20 polypeptide” permits amino acid replacements in the PH20 polypeptide but only “so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Ex. 1001, 47:13–15. Indeed, while some of the language in the above paragraph is permissive in nature, i.e.., describing the number of amino acid replacements a modified PH20 polypeptide “can have” or “[t]ypically . . . contains” or the other modifications the polypeptide “can include,” the phrase “so long as” is not. See Ex. 1001, 47:8–22. This distinction demonstrates that hyaluronidase activity is not an optional feature of a non-limiting example, but a requirement of the “modified PH20 polypeptide” defined and claimed in the ’773 patent. See Alynylam Pharms., Inc. v. Moderna, Inc., 138 F.4th 1326, 1333 (Fed. Cir. 2025) (explaining that the “contrast” between “non-limiting terms” and more definitive statements may indicate that the latter is definitional).” slip op. at 13
