  • Skill levelSkill level patent owner adoptedDecided for patent owner

    “We agree with Patent Owner’s proposed definition of a POSITA, to the extent that it aligns with the level of skill portrayed by the ’050 Patent. As discussed above, the ’050 Patent does not does not provide one with any technical direction for making and using a multi-restaurant embodiment that avoids or solves calculation/extraction problems due to disparate client (e.g., restaurant) systems. The ’050 Patent also does not provide one with any technical direction for scaling up and/or transitioning to a cloud-based system. We infer from this that a POSITA would have the education and the experience enabling him/her to effectively and economically handle these tasks without technical direction, despite the problems associated therewith. Put another way, the actual application of these technical endeavors would not be beyond his/her skill. Although Petitioner provides a slightly different expression for the level of ordinary skill in the art (see Pet. 9–10), it substantively agrees with Patent Owner’s proposed level of skill and adopting Petitioner’s precise level of ordinary skill would not change our decision.” slip op. at 9

    “with a restaurant’s timeclock programs, time and attendance systems, and/or payroll processing systems. See Ex. 1004 ¶¶ 69, 108. Webb discloses that, in a restaurant setting, a POS system can be communicatively coupled to a time and attendance server. See Ex. 1006, Abstract, 24:51–60, Figs. 1A, 1B. Thus, Marshall and Webb describe similar and compatible systems in the same field of art—systems for tracking employee and sales information in the hospitality business. And Petitioner provides evidence that it would have been obvious to a POSITA to combine these teachings in the claimed manner. See Ex. 1002 ¶¶ 207–212. Patent Owner argues that Webb “does not cure the deficiencies” of Marshall. PO Resp. 41. However, as discussed above, we disagree with Patent Owner regarding Marshall’s deficiencies. Thus, Webb need not cure these alleged deficiencies in Marshall.10 Patent Owner does not otherwise contest Petitioner’s contention with respect to this asserted ground of unpatentability. Consequently, we conclude that, on the record before us, Petitioner has proven that claims 4–7, 9, and 11–13 would have been would have been obvious over Marshall and Webb. 10 Patent Owner also mentions that there is “simply no motivation to combine Marshall and Webb.” PO Sur-Reply 7; see also PO Resp. 42.

See Pet. Reply 6. Petitioner also points out in its Reply that Patent Owner (and its expert) fail to address Marshall’s disclosure that the server executing the GrataSoft software can be separate (i.e., not co-located) with the POS server executing the Aloha software. Id. at 10. In Patent Owner’s Sur-Reply, these topics remained undiscussed. See PO Sur-Reply 1–6. Both aspects of Petitioner’s contentions support that Marshall’s system does disclose a gratuity management system that is separate and distinct from the client POS servers. Patent Owner argues that there would be problems “associated with calculations of gratuities based on client-specific information extracted from disparate, ad hoc client business systems.” PO Resp. 27–28; Ex. 2006 69–73. Patent Owner also argues that there would be “problems associated with scale-up and transitioning to a cloud-based system, and associated cost and security issue. PO Resp. 27; Ex. 2006 ¶¶ 87–91. However, as discussed above, the ’050 Patent portrays that a POSITA would have the education and experience enabling him/her to effectively handle the conversion of a singlerestaurant system to a multi-restaurant system; and to transition to a safe and secure cloud system in a cost/time effective manner. Thus, these problems would not detract from the obviousness of a multi-restaurant and/or cloud-based version of Marshall’s invention. Patent Owner does not otherwise contest Petitioner’s contention with respect to this asserted ground of unpatentability. Consequently, we conclude that, on the record before us, Petitioner has proven that claims 1–3, 8, and 10 would have been would have been obvious over Marshall.” slip op. at 16

    “known that a spiral flute helps to lift swarf away from the cutting surface. Pet. 67 (citing Ex. 1004 ¶¶ 201–202). The testimony of Petitioner’s expert states that a person of ordinary skill in the art would have known that “the spiral shape of the flute side walls was desirable since it helps to lift chips, or swarf, away from the cutting surface and evacuate it from the hole being cut.” Ex. 1004 ¶ 202. This makes intuitive sense, as a wall perpendicular to the surface would push accumulated chips along, whereas the wedge shape of the spiral will lift them away from the cutting surface. According to Petitioner, a person of ordinary skill in the art would have been motivated to modify Zhou’s flute to arrange the cutting edges such that they, as a whole, have a spiral shape in order to achieve these chip-lifting benefits. Thus, we find that a person of ordinary skill in the art at the time of the invention had a reason to include the known feature of cutting tips that spiraled around the cone portion, in order to achieve the benefit of providing better chip removal.” slip op. at 27

Patent Owner asserts that these are “observations of testing.” Opp. Mot. Excl. 10. We note that this document was produced by Astro, a party with ties to Patent Owner. Notwithstanding, Patent Owner attempts to attribute the statements in this document to another third party (not Astro). We agree with Petitioner that Patent Owner is attempting to use these statements for the truth of the matter asserted. See, e.g., Resp. 50–51 (alleging that the third party “was [] impressed with their performance” and citing to Exhibit 2059 as evidence of “initial testing documents”). Accordingly, Patent Owner is not only attempting to use these documents for the truth of the matter asserted, but Patent Owner is attempting to attribute them to a party different from the party that made the statements. We do not find any exceptions to the hearsay rule to be applicable here. In addition, Exhibit 2059, as offered, is misleading and confusing. We exclude Exhibit 2059. 5. Exhibit 2060 Exhibit 2060 appears to contain a series of slides and notes, as would be used in a presentation. The document appears to be that of a third party. Patent Owner asserts that the content in this exhibit demonstrates the third party’s “strong desire to copy” the claimed invention. See, e.g., Resp. 51, 59. Assuming they are what they are alleged to be, then these are out-of- court statements by a third party being used to prove the truth of the matter asserted—that an employee of the third party thought highly of Patent Owner’s licensed drill bits.

    “3. Objective Indicia of Non-Obviousness Patent Owner asserts that objective indicia of non-obviousness overcomes any prima facie obviousness case. Resp. 44–60; Sur-reply 15– 26. Patent Owner first asserts that there is a nexus between the challenged claims and its alleged objective indicia. Resp. 46–49; Sur-reply 15–19. Patent Owner also alleges that its evidence shows copying (Resp. 49–55; Sur-reply 20–21), industry praise (Resp. 55–56; Sur-reply 21–22), commercial success (Resp. 56–58; Sur-reply 22–26), and satisfaction of a long-felt need (Resp. 58–60). Petitioner disputes these allegations. Reply 18–28. a) Nexus Patent Owner bears the burden of establishing nexus. WMS Gaming Inc. v. Int’l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999). A presumption of nexus is only appropriate if “the patentee shows that the asserted objective evidence is tied to a specific product and that product embodies the claimed features, and is coextensive with them.” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (cleaned up). The coextensiveness requirement is not met simply by showing that “the patent claims broadly cover the product that is the subject of the evidence of secondary considerations.” Id. at 1377. Coextensiveness can be thought of as “the degree of correspondence between a product and a patent claim.” Id. at 1374. “[T]he existence of one or more unclaimed features, standing alone,” does not necessarily defeat coextensiveness. Id. Instead, “the concept of unclaimed features is best viewed as part of a spectrum.” Teva Phrama. Int’l GmbH v. Eli Lilly and Co., 8 F.4th 1349, 1361 (Fed. Cir. 2021). “The presumption analysis requires the fact finder to consider the unclaimed features of the stated products to determine their level of significance and their impact on the correspondence between the claim and the products.” Id. (citing Fox Factory, 944 F.3d at 1375). The nexus analysis should focus on and consider the difference between the prior art and the claimed invention, and the extent to which the objective indicia speaks to these gaps. Campbell Soup Co. v. Gamon Plus, Inc., 10 F.4th 1268, 1278 (Fed. Cir. 2021) (“[T]o establish a nexus, [the patent owner] needed to present evidence that the commercial success and praise of the [product] derived from those ‘unique characteristics.’”) (citing Fox Factory, 944 F.3d at 1373–74). Simply providing evidence tied to features already present in the prior art does not satisfy the inquiry. Id. (“objective indicia must be linked to a [] patent claim’s unique characteristics”); Fox Factory, 944 F.3d at 1378 (stating that for patents claiming combinations of prior art features, a patentee must show that the secondary considerations evidence is “attributable to the claimed combination of [prior art features], as opposed to, for example, prior art features in isolation or unclaimed features”). Patent Owner’s assertions regarding nexus are conclusory and extensively incorporate by reference other documents. See generally Resp. 46–49; Sur-reply 15–19. Patent Owner begins by citing to sixteen claim charts. Resp. 46 (citing Exs. 2074–2089). Patent Owner then alleges that the products it has licensed “are coextensive with the patented invention” because all of them are drill bits. Id. at 47.

Accordingly, we determine that the patentee has not acted as a lexicographer to set forth a definition of “web browsing interaction data” in the written description. c.

In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet. Reply 24; Ex. 1017, 31–34 (final written decision determining obviousness of claims 9, 10, 14, and 16 of the ’473 patent over Wu and Sabat-426); Ex. 1072, 5 (summarizing the final written decision regarding the packetizing limitations), 10–16 (finding no error in the determinations regarding the packetizing limitations).” slip op. at 12

    “would have a bachelor’s degree in electrical engineering (or equivalent field) with 2–3 years of work experience in wireless communications.” Pet. 21 (citing Ex. 1003 ¶¶ 20–22). Patent Owner argues that one of ordinary skill in the art “would have an educational background in electrical engineering and experience in the design of wireless communication systems,” and “[m]ore particularly, a POSA would be a person with a bachelor’s degree in electrical engineering (or a similar technical degree or equivalent work experience) and at least 3 years of experience working with wireless communication systems.” PO Resp. 13. We found in the Decision on Institution that Patent Owner’s definition was generally consistent with Petitioner’s definition, with the exception of requiring 3 years or more (as opposed to 2 to 3 years) of work experience in wireless communication systems and, for the purpose of institution, we adopted Petitioner’s provided definition for the level of skill of a person of ordinary skill in the art as reasonable and consistent with the prior art.

    “a . . . set of radio resources” is not limited to and does not necessarily include configuration information that is required to or used to reconfigure remote radio units. As Petitioner argues, there does not appear to be any indication in the specification and other intrinsic evidence that “digital representation” should be given more than its ordinary meaning, or that an underlying construction of “radio resources” would not be applied to this claim term, which explicitly includes “radio resources.” Pet. Reply 9–10 (citing Ex. 1001, representation” in the specification of the ’499 patent). Our construction is further supported by the language of the claims, which requires that each “set of radio resources” is “for transmission at an antenna of the first remote unit.” Ex. 1001, 14:17–19, 14:22–24, 15:3–5, 15:8–10, 16:6–8, 16:11–13. With respect to the “digital representation” of “set[s] of radio resources,” the specification of the ’499 patent describes that in the downlink (base station to DRU antenna) path for data, RF signals received at the DAU from base station(s), are down-converted, digitized, and further processed resulting in “independently serialized, parallel data streams” that are delivered to DRUs. Ex. 1001, 4:63–5:12. Petitioner contends that this description of delivery of a digitized version of an RF signal to DRUs describes the sending/transmission of a digital representation of the radio. Pet. 9–10. While Patent Owner appears to argue that a “digital representation” of a radio resource would be only an “identifier” of, e.g., an RF carrier (PO Resp. 18), this does not appear to be supported by the specification or the cited testimony of Dr. Chrissan. We do not see a reason to relate “digital representation of . . . a set of radio resources” in the claims to the description in the ’499 patent specification of the remote configuration of DRU parameter settings via the DAU, including detecting or determining radio resources assigned to a DRU and configuring the DRU, turning on and off individual carriers transmitted and received by a DRU. PO Resp. 16–18 (citing Ex. 1001, 4:50–62, 6:31–44, 7:44–50, 12:15–39, 12:58–13:2). No cited portion of the specification describes these signals sent from a DAU to control a DRU as digital representations of a set of radio resources. While Patent Owner cites, in support, Dr. Chrissan’s declaration, Dr. Chrissan does” slip op. at 16
