“Owner’s interpretation of “carrier” as meaning “one or more components for supporting ROSA components such as an AWG.” Dec. 9 (quoting Pet. 11). For our analysis of Petitioner’s challenges, we referred to this interpretation of “carrier” as Petitioner’s second alternative construction. Id. We also noted that Petitioner appeared to dispute Patent Owner’s interpretation when it argued that “carrier” should mean “a ceramic or silicon substrate.” Id. (quoting Pet. 10). We referred to this interpretation of “carrier” as the first alternative construction. Id. Rather than resolve this apparent dispute about the meaning of “carrier,” we found that both of Petitioner’s anticipation challenges failed under both interpretations of “carrier.” Id. at 10–26.

Petitioner fails to reconcile how its assertions that the first and second ferromagnetic layers, which are mapped to the totality of layers of 115 and 175, meet the limitation that the first and second ferromagnetic layers are each “entirely crystallized” when Petitioner relies only a thin layer, that is, a portion, of the 115 and 175 layers for the teaching that the respective layers are entirely crystallized.

Any final decision shall be based on the full trial record, including any response timely filed by Patent Owner. Any arguments not raised by Patent Owner in a timely filed response may be forfeited. For the reasons stated below, we determine that Petitioner has established a reasonable likelihood that it would prevail with respect to at least one claim.

Patent Owner specifically argues that 11 Patent Owner also argues that Petitioner does not establish that Haddad138 anticipates claim 2. Prelim. Resp. 5–7. We do not address the anticipation challenge at this time. “Petitioner does not offer any showing on any motivation to modify Figure 9 of Haddad138 to change the configuration from a FSI to BSI architecture.” Id. at 8. On this record, Patent Owner’s argument does not undermine Petitioner’s persuasive showing. As Petitioner argues (Pet. 29), Haddad138 teaches that its “present disclosure” (which would include the Figure 9 disclosure) can be adapted for a front side illumination (FSI) or back side illumination (BSI) configuration. Ex. 1012 ¶ 48. The express teaching of Haddad138 provides motivation to modify Figure 9 of Haddad138. Patent Owner also argues that Petitioner “offers no showing that a POSITA would be able to modify the embodiment of Figure 9 to be back side illuminated with a reasonable expectation of success.” Prelim. Resp. 9. Patent Owner’s argument again does not undermine Petitioner’s persuasive showing. Petitioner cites Haddad138 expressly teaching a FSI or BSI configuration. Pet. 29 (citing Ex. 1012 ¶ 48). Haddad138’s teaching is sufficient, on this record, to establish a reasonable likelihood of Petitioner establishing a reasonable expectation of success at trial.

“discretionary denial under § 325(d).

- Skill levelSkill level board ownOther
“the art.7 On consideration of the record, specifically the patent and cited prior art, we find Petitioner’s proposed educational levels and subject matter (bachelor’s degree in electrical or mechanical engineering) more appropriate. Specifically, Patent Owner’s reference to a degree in computer science does not appear relevant to the claimed electro-mechanical device. We find Patent Owner’s proposed hands-on experience more persuasive as Petitioner’s definition is too vague (“generally familiar”) to assist our determination. On this record and for the purposes of institution, we find that a person of ordinary skill in the art relevant to the challenged claims, as of the earliest claimed priority date, would have a bachelor’s degree (or equivalent) in electrical engineering or mechanical engineering, and would have two years of experience in designing and/or implementing hardware components for computers, servers, and/or other electronic devices. We further determine that more experience could compensate for the absence of a bachelor’s degree. The level of skill is reflected by the testimony of the parties’ declarants and the prior art of record.” slip op. at 15
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner
“We determine that the plain meaning of claim 1 supports Patent Owner’s interpretation. Claim 1 recites a body, provided with a fan in center of the body, an illumination area on at least two sides of the fan at top of the body, a power socket and a first connector on one side of the body, and a second connector on another side of the body . . . such that when the power socket on the one side of the body is supplied with power, the fan and the illumination area of the body are respectively driven into rotation and illumination . . . Ex. 1001, 4:5–9 (emphasis added). Claim 1 expressly recites three body locations: “the top of the body,” “one side of the body,” and “another side of the body.” Id. “A power socket and a first connector” are listed together in the same clause “on one side of the body.” Id. The plain language of the claim further supports that “one side of the body” includes both power socket and first connector, as the limitation is repeated later in the claim: “the power socket on the one side of the body.” See id. at 4:12 (emphasis added). The location of the second connector is defined in relation to the one side with the first connector. See id. at 4:5–9. Accordingly, the plain meaning of claim 1 defines three sides of the claimed body, a top of the body (with an illumination area on two sides of the fan), one side of the body with a power socket and a first connector, and another side of the body with a second connector. See id. For purposes of this Decision, we determine that no other claim terms require express construction. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“We agree that Petitioner’s obviousness rationale appears to be based on the challenged patent’s disclosure—at least in part. See Pet. 46–47 (citing Ex. 1001, 1:25–50), 61 (citing Ex. 1001, 2:34–40).

Mahon’s corresponding testimony relies on the same parts of the challenged patent, adding little additional technical reasoning or support from the prior art of 8 Petitioner cites “Section 5.8a.1.3.”, but the quoted passage appears in Section 5.8.1.3. Pet. 60 (emphasis added). challenged patent itself raises the possibility that Petitioner has succumbed to impermissible hindsight bias. See Zoltek Corp. v. United States, 815 F.3d 1302, 1313 (Fed.

VGO Commc’ns, Inc., 751 F.3d 1327, 1351 (Fed. Cir. 2014) (“It appears that [the expert] relied on the . . . patent itself as her roadmap for putting what she referred to as pieces of a ‘jigsaw puzzle’ together.”). Even so, the preliminary record also indicates that it may be inherent in an NB-IoT system that “DCI indicating an SC-MCCH change notification must be transmitted in a different subframe from the DCI indicating a resource for the updated SC-MCCH information.” Pet. 61.

- Novelty / Anticipation (§102) › Prior-art status of a reference › Patents / published applications (effective date, provisional support)Reference is prior artDecided for patent owner
“We see no basis for using China Standard Time here. “The time and date of receipt of an application filed via EFS-Web is the local time and date in USPTO headquarters in Alexandria, Virginia.” Manual of Patent Examining Procedure (MPEP) § 502.05 I.C.2 (9th ed. Rev. 07.2015, Nov. 2015) (emphasis added).7 The MPEP provides an example of how an application filed from the Pacific Time Zone would receive the filing date as of the USPTO’s local time: For example, if an applicant in California officially files a patent application with the USPTO through EFS-Web by clicking on the SUBMIT button at 10 p.m. Pacific Time in California on May 1, that application would be officially received by the USPTO at 1 a.m., local time (i.e., Eastern Daylight Time) on May 2. Accordingly, the application would receive a filing date of May 2. Id. Thus, we disagree with Patent Owner’s argument that Fujishiro is not prior art for this reason. Prelim. Resp. 28–29.” slip op. at 18
