RulingsInstitution decision- PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Decided for petitioner
“based on Petitioner’s first stipulation filed on December 18, 2024.15 Prelim. Resp. 13–15. Patent Owner does not address Petitioner’s updated second stipulation filed on April 8, 2025. This updated second stipulation mitigates any concerns of duplicative efforts between the district court and the Board, as well as concerns of any potentially conflicting decisions. See Sand at 12. We therefore find that this factor weighs against exercising discretion to deny institution. See id., n.5. 5. Whether Petitioner and the Defendant in the Parallel Proceeding are the Same Party Whereas Petitioner does not address factor 5, Patent Owner argues that the parties to this proceeding are both in the related district court litigation. Pet. 98–99; Prelim. Resp. 15. While it is common in IPR proceedings for the petitioner and patent owner to also be parties in a related district court proceeding, this factor weighs slightly in favor of discretionary denial.

“c) Conclusion Regarding Claim 1 Based on the current record, we determine that there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 1 is unpatentable as obvious over the combination of Mazumder and Mori. Accordingly, we institute inter partes review with respect to all claims and all grounds asserted in the Petition. 5. Claims 3, 5–7, 9, 10, and 19–22 Because Petitioner demonstrates a reasonable likelihood of success in proving that at least one claim of the ’324 patent is unpatentable, we institute on all grounds and all claims raised in the Petition. See 37 C.F.R. § 42.108(a). Therefore, at this stage of the proceeding, it is not necessary for us to provide an assessment of every challenge raised by Petitioner, especially, as in this case, when Patent Owner does not separately argue those claims. See Prelim. Resp. 28–46. Those challenges, in our view, are best left for trial after full development of the record.” slip op. at 27

“Mazumder because “the presentation of both image types would have beneficially aided the remote user to more easily visually compare the actual image and virtual image to quickly identify any defects or problems with the fabrication process.” Pet. 23–24 (citing Ex. 1003 ¶ 113). Patent Owner argues that “it is hindsight to use ‘the invention to define the problem the invention solves.’” Prelim. Resp. 43 (quoting Mintz v. Dietz & Watson, Inc., 679 F.3d 1372, 1377 (Fed. Cir. 2012); citing AT&T Services Inc. et. al. v. Innovative Sonic Ltd., IPR2024-001143 (PTAB Feb. 11, 2025)). According to Patent Owner, because neither Mazumder nor Mori teaches visual comparison of image types, the idea to improve the Mazumder-Mori combination by simultaneously displaying different image types and thus permitting visual comparison must be driven by hindsight. Id. at 44–45. But Petitioner cites evidence other than the ’324 patent to support the person of ordinary skill in the art having a desire to visually compare the different images presented in the Mazumder-Mori combination. Pet. 23–24 (citing Ex. 1003 ¶ 113). Specifically, Dr. Wolfe testifies that “the presentation of the actual images captured by the camera and the virtual images simultaneously within the user interface would have beneficially aided the remote user to more easily visually compare the actual image and virtual image to quickly identify any defects or problems with the fabrication process” and that a person of ordinary skill in the art would have recognized this. Ex. 1003 ¶ 113. Thus, Petitioner has shown sufficiently for the purpose of the present decision that Mori teaches or suggests the disputed limitation of claim 1.

Petitioner further states that “a person with less formal education but more experience, or more formal education but less experience, could have also met the relevant standard for a POSITA.” Id. Patent Owner submits a similar definition (see Prelim. Resp. 13–14), but states that a POSITA “would understand that . . . the subject of the patent is a software-based solution to broadcasting multimedia streams, and the skillset and expertise in hardware-based systems would not make one knowledgeable about software-based systems.” Prelim.

Rather, claim 1 only requires that the request is received from the content provider. Ex. 1001, 14:51–54.

“In this case, Mr. McAlexander meets both Petitioner’s and Patent Owner’s proposed level of skill in the art. As a result, we are persuaded Mr. McAlexander has the requisite skill and relevant expertise to offer testimony in this matter. For example, Mr. McAlexander has a Bachelor’s Degree in Electrical Engineering and far more than 2 years of experience in the electrical engineering field. Ex. 1027, 3–6, 7. In addition, Mr. McAlexander has provided expert consulting services in a wide range of technology areas involving the process and design of electro-mechanical consumer products. Ex. 1003 ¶ 5.

“B. Discretionary Denial Based on Hulu The Hulu decision held that “[b]ecause the patent claims already stand invalid, it is unnecessary to institute another proceeding to review them for patentability under other grounds.” Hulu at 2. The decision reasoned that “[i]n the event the Federal Circuit reverses the district court’s decision, Petitioner may raise such invalidity arguments in the district court on remand.” Hulu at 3 (remanding the panel’s institution decisions and denying institution). The Hulu rationale is grounded in the statutory estoppel provisions of 35 U.S.C. § 315(e) that apply only to a “final written decision;” statutory estoppel does not prevent a petitioner from raising the same invalidity grounds in district court if the petition is denied. See Intuitive Surgical, Inc. v. Ethicon LLC, 25 F.4th 1035, 1041 (Fed. Cir. 2022) decision.”). Even if inter partes review is instituted but later terminated with respect to a petitioner, e.g., after settlement, no statutory estoppel attaches to the petitioner, a real party in interest, or privy. See 35 U.S.C. § 317(a) (“If the inter partes review is terminated with respect to a petitioner under this section, no estoppel under section 315(e) shall attach to the petitioner, or to the real party in interest or privy of the petitioner, on the basis of that petitioner’s institution of that inter partes review.”). Thus, discretionary denial would not eclipse Petitioner’s ability to assert invalidity of the Challenged Claims in the District Court litigation. The Petition explains that the District Court granted a Motion to Dismiss and found all of the Challenged Claims to be patent ineligible under 35 U.S.C § 101. 130 Pet. 2 (citing Ex. 1025, 10, 14; DKR Consulting LLC v.

In the Show Cause Paper, Petitioner confirms the scope of the District Court Judgment as applying to all of the challenged claims of the ’678 and ’237 patents. See Show Cause Paper at 6 (“All challenged claims are subject to the district court’s Order and Judgment.”). All of the Challenged Claims in this proceeding having been found invalid, we see no reason to institute inter partes review.

“B. Discretionary Denial Based on Hulu The Hulu decision held that “[b]ecause the patent claims already stand invalid, it is unnecessary to institute another proceeding to review them for patentability under other grounds.” Hulu at 2. The decision reasoned that “[i]n the event the Federal Circuit reverses the district court’s decision, Petitioner may raise such invalidity arguments in the district court on remand.” Hulu at 3 (remanding the panel’s institution decisions and denying institution). The Hulu rationale is grounded in the statutory estoppel provisions of 35 U.S.C. § 315(e) that apply only to a “final written decision;” statutory estoppel does not prevent a petitioner from raising the same invalidity grounds in district court if the petition is denied. See Intuitive Surgical, Inc. v. Ethicon LLC, 25 F.4th 1035, 1041 (Fed. Cir. 2022) (“estoppel is triggered when an IPR proceeding results in a final written decision.”). Even if inter partes review is instituted but later terminated with respect to a petitioner, e.g., after settlement, no statutory estoppel attaches to the petitioner, a real party in interest, or privy. See 35 U.S.C. § 317(a) (“If the inter partes review is terminated with respect to a petitioner under this section, no estoppel under section 315(e) shall attach to the petitioner, or to the real party in interest or privy of the petitioner, on the basis of that petitioner’s institution of that inter partes review.”). Thus, discretionary denial would not eclipse Petitioner’s ability to assert invalidity of the Challenged Claims in the District Court litigation.” slip op. at 8

The Board held claims 1–48 not shown unpatentable on any of six § 103 grounds because the asserted references did not teach the required housing aperture and the proposed combinations lacked adequate support.
RulingsFinal written decision- Skill levelDecided for patent owner
“time it was made, we consider the level of ordinary skill in the pertinent art at the time of invention. Graham, 383 U.S. at 17. Petitioner does not provide its own definition of the level of ordinary skill in the art. Instead, Petitioner asserts: In previous litigation involving the ’881 patent – the parent patent to the ’864 patent (Fuma International LLC v. R.J. Reynolds Vapor Company, Case No. 1:19-cv-260 (M.D.N.C. 2019)) with an identical specification – Patent Owner’s predecessor-in-interest asserted that a person of ordinary skill in the art (“POSITA”) at the time of the purported invention would have had a mechanical or electrical engineering degree, industrial design degree, or a similar technical degree, or equivalent work experience, and 5 to 10 years of experience in electromechanical devices. Ex. 1007, ¶¶14-17. Pet. 11–12; see also Ex. 1007 ¶ 16 (Mr. Sturges testifying that he meets “that qualification” without affirmatively providing a definition for a POSITA). Before institution, Patent Owner stated it did not challenge this definition (Prelim. Resp. 9), and we adopted Petitioner’s proposed definition in our Decision granting institution. During trial, Patent Owner also adopted this definition. PO Resp. 10–11. Upon a complete record, we see no reason to change and we maintain the agreed upon definition of a POSITA.” slip op. at 12
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“Patent Owner argues, and Petitioner does not dispute, that an aperture is a “hole” or an “opening.” See, e.g., id. at 21; see generally Reply. Patent Owner asserts that, in the proper context, the plain and ordinary meaning of a housing having an aperture is that the aperture is a hole, or an opening, on the housing structure itself. Id. at 21–22. We agree. In order for an object to have an “aperture” or an “opening,” the aperture or opening must be on the structure itself and not on a separate object that is located in the structure. This construction is in accord with the Specification of the ’864 patent, which refers to apertures in context of the structure on which they are located. See, e.g., Ex. 1001, 6:12–18 (referring to a first end comprising a first aperture), 7:11–12, 7:65–67 (stating that the wall of an airflow passageway may have apertures).” slip op. at 18
- Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalTerm construed patent owner constructionDecided for patent owner
“large obstructions that force the air flow to near the peripheral surface of the housing, render the passageway non-central. During prosecution of the ’864 patent, the Examiner rejected certain claims (i.e., dependent claims 49, 63, and 75) over Han. To overcome this rejection, the applicant argued that Han cannot meet the limitation “wherein the airflow passageway extends centrally and axially from the first aperture to the second aperture.” Ex. 1002, 273. The applicant explained that Han does not meet this limitation because Han’s shell (b) does not include a central airflow passageway and instead places the perforated component for liquid storage (9) in the middle of shell (b), thereby forcing the airflow around the peripheral surface of the perforated component for liquid storage (9). Id. at 273–274. The examiner relied on this argument in determining that the applicant had overcome an earlier rejection. Id. at 195. Thus, some obstructions of a passageway render the passageway non-central; in particular those obstructions that force air to flow near the peripheral surface of the housing are large enough to render the passageway non-central.” slip op. at 22
- Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableMotivation not foundNot shown unpatentable
“lacks motivation and is plagued by improper hindsight.” Sur-reply 15–17. On the record developed during trial, we agree with Patent Owner that Petitioner has not shown by a preponderance of the evidence that a person of ordinary skill in the art would have had a reason to combine the teachings of Xia with those of Wang to arrive at the claimed limitations. Relying on the testimony of Patent Owner’s declarant Dr. Singhose, Petitioner argues that a person of ordinary skill in the art “would have known a central straight path has less airflow resistance than a circuitous one.” Reply 22 (citing Ex. 1035, 127:15–128:9). But the same witness also testified that higher airflow resistance might be desirable and explained that providing more resistance to airflow might result in improved mixing. Ex. 1035, 21:21–22:12, 127:20–24, 170:10–14. In addition, Dr. Singhose testifies that the complicated design of the airflow passageway in Xia “serves important functions,” including “allow[ing] large droplets to be reabsorbed by the liquid-guiding mechanism,” allowing “excessive liquid in the airflow [to] condense,” and “prevent[ing] the chemical liquid from being sucked into the mouth.” Ex. 2022 ¶ 190 (citing Ex. 1004, 11, 13–14, 16). Although Petitioner’s declarant Dr. Sturges testifies that a straight airflow passageway “would provide improved, smoother air flow,” he does not provide any evidence supporting the view that the air flow would be improved. Ex. 1007 ¶ 144. We credit the testimony of Dr. Singhose that using a straight passageway in Xia would have been detrimental rather than beneficial. Ex. 2022 ¶ 190. slip op. at 40
