“II. ANALYSIS A. Level of Ordinary Skill in the Art Relying on the Schubert Declaration, Petitioner proposes that a person of ordinary skill in the art “would have had a bachelor’s degree in electrical engineering, physics, materials science, or a related discipline, and 6 years of 1 The Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112–29, 125 Stat. 284 (Sept. 16, 2011), includes amendments to Section 103 that became effective on March 16, 2013. Because the challenged claims issued from an application filed before March 16, 2013, we apply pre-AIA law. See Pet. 2; Ex. 1001, codes (22), (30). 2 US 2009/0021955 A1, published January 22, 2009 (Ex. 1004, codes (10), (43)) (“Kuang”). Petitioner contends that Kuang is prior art to the ’546 patent at least under pre-AIA 35 U.S.C. § 102(b). Pet. 2. 3 US 2012/0050606 A1, published March 1, 2012 (Ex. 1005, codes (10), (43)) (“Debevec”). Petitioner asserts that “[b]ecause Debevec was filed prior to the priority date of the ’546 patent, it qualifies as prior art at least under pre-AIA 35 U.S.C. § 102(e).” Pet. 2. 4 US 6,774,584 B2, issued August 10, 2004 (Ex. 1008, codes (10), (45)) (“Lys”). Petitioner contends that Lys is prior art to the ’546 patent at least under pre-AIA 35 U.S.C. § 102(b). Pet. 2–3. 5 JP2006-228529, published August 31, 2006 (Ex. 1006, code (43)) (“Hiroyuki”). We refer herein to the certified English translation filed as Exhibit 1007. Petitioner contends that Hiroyuki is prior art to the ’546 patent at least under pre-AIA 35 U.S.C. § 102(b). Pet. 2. practical experience in designing or fabricating LED lighting systems, including controlling and driving LEDs,” or “[a]lternatively . . . would have had a master’s degree and four years of experience, or a Ph.D. degree and two years of experience.” Pet. 5 (citing Ex. 1003 ¶ 31). Patent Owner applies Petitioner’s asserted level of ordinary skill in the art. PO Resp. 7–8. For the purposes of this Decision, we adopt the assessment offered by Petitioner as it is consistent with the ’546 patent and the prior art before us. See Okajima v.

“The “context” is typically evaluated by reviewing the intrinsic record. See e.g., Regeneron, 130 F.4th at 1380–84. Here, as discussed above, the ’546 patent has multiple disclosures where a curtain lamp has a single light-emitting diode in one light-emitting diode string. See Ex. 1001, 1:33–36, 6:15–20, 6:27–40, 8:25–45. In particular, the ’546 patent similarly discloses a first curtain lamp with one LED in one light string, as well as a second curtain lamp, which provides further support for Petitioner’s proposed interpretation. Id. at 8:25–45. Although Patent Owner argues that Figures 7 and 8 disclose multiple LEDs and light strings in curtain lamps, other embodiments and claims explicitly indicate single components in a “curtain lamp.” “[T]here is a strong presumption against a claim construction that excludes a disclosed embodiment.” See In re Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1324 (Fed. Cir. 2011). Given that certain embodiments and claim 8 disclose a curtain lamp with one light string with one LED, we decline to interpret the claim to prohibit Petitioner’s interpretation. Additionally, we do not find that Petitioner’s claim interpretation renders the claim terms nonsensical or illogical. See Becton, 616 F.3d at 1255. Patent Owner asserts otherwise, arguing that Petitioner’s interpretation is based upon a “nonsensical” or “absurd[]” argument, there is no reason to have both a master and slave control unit to operate a single LED, and the interpretation renders most of the components superfluous. See PO Sur-reply 12; PO Resp. Supp. Br. 5. As discussed above, however, although the ’546 patent does not appear to provide any explanation for why there are master and slave control units to operate a single LED, the patent nevertheless discloses that in embodiments. This situation is also distinguishable from Becton, where “unequivocal language” of the claim recited “spring means ‘connected to’ the hinged arm,” such that interpreting the spring means and the hinged arm as the same structure would have rendered the claim nonsensical. Becton, 616 F.3d at 1254–55. Becton further found that interpreting the spring means and hinged arm as the same structure would be inconsistent with descriptions of the elements in the specification. Id. Here, in contrast, the ’546 patent Specification is replete with disclosures of a curtain lamp having one light string with one LED, and claim 8 is directed to the same. Accordingly, we adopt Petitioner’s interpretation of these claim elements.” slip op. at 36

“Although Patent Owner argues that Petitioner’s arguments in the Reply on “light strings” and “curtain lamp” as they relate to a single LED are improper, we do not agree. As Patent Owner acknowledges, the Petition and Dr. Schubert’s original declaration stated that a “curtain lamp” is “commonly understood to be one or more light strings.” See PO Sur-reply 12; see also Pet. 8; Ex. 1003 ¶ 37. Patent Owner did not contest Petitioner’s interpretation in its Response. See PO Resp. 15. Patent Owner did, however, argue that Kuang did not teach or suggest “light strings” in any form and therefore did not teach a “curtain lamp” under Petitioner’s definition of the same. PO Resp. 15–17. A petitioner reply may respond to arguments raised in a patent owner’s response under 35 U.S.C. § 42.23(b), and here Petitioner’s argument that a light string may have a single LED is properly presented in its Reply in response to Patent Owner’s arguments. Further, Patent Owner was not only aware that Petitioner had taken the position that a “curtain lamp” could be a single “light string,” but Patent Owner also did not dispute Petitioner’s interpretation.8 Our view, therefore, is that Petitioner’s argument that a curtain lamp may be a single LED is proper because it is corollary to Petitioner’s reply arguments on light strings. That is, Petitioner’s assertion follows from the reply arguments on light strings and the unopposed interpretation of curtain lamp as a single light string. Additionally, to the extent there could be any prejudice to Patent Owner by these light string and curtain lamp arguments, Patent Owner has had opportunities to address them by supplemental briefing.” slip op. at 32

RulingsRemand decision- RemandOther
“Reviewing Patent Owner’s arguments and Petitioner’s assertions, we remain persuaded that one of ordinary skill in the art would have applied the previous power level, i.e., the power level prior to the interruption, and also an offset according to the process illustrated in Agin’s Figure 2. Agin makes clear that its processes in Figure 2 are run “[i]f transmission is not resumed after a transmission interruption” and “[i]f transmission is resumed after a transmission interruption.” Ex. 1004 5:44–50. Figure 2 of Agin is used to make a determination of what the power level would be after an interruption, and that process should be followed, for the first transmission, as well as subsequent transmissions. Agin does not address a separate procedure for the initial transmission after an interruption because the process in Agin’s Figure 2 is generally applicable to all interruptions.

“As to the claim requirement that the direct memory access device concurrently write the packet buffer memory and the protocol stack layer memory, Petitioner asserts that neither Cornett nor Paatela explicitly describes the timing of packet writing. Pet. 42. Petitioner asserts, however, that Nelson discloses writing a packet header separately and in parallel with writing the entire packet. Id. (citing Ex. 1006, 6:66–7:4; Ex. 1003 ¶ 89). Indeed, Nelson explains that the parallel storage action “avoid[s] having to read the frames out of the [larger frame] buffer” when reading a header, which eliminates the need for a separate reading step and “allows the routing decision to be made before the [frame] buffer becomes available.” Ex. 1006, 2:1–22 (containing the quoted language), 7:1–4 (describing “parallel . . . storage”). Petitioner asserts that it would have been obvious to write the packet header at the same time as writing the entire packet in Cornett, because Cornett, Paatela, and Nelson are concerned with speed, and writing in parallel would increase speed (vs. writing serially). Id. at 43–44 (citing Ex. 1003 ¶ 90); see also id. at 26 (similar argument). Reviewing Petitioner’s position with respect to independent claim 13, we determine that Petitioner has addressed each limitation in sufficient detail and with adequate citations to the record. Petitioner has also provided sufficient reasons for combining the teachings of Cornett, Paatela, and Nelson with a reasonable expectation of success. Reviewing the record before us, we determine that Petitioner has established a reasonable likelihood of success in showing that claim 13 would have been obvious in view of Cornett, Paatela, and Nelson.” slip op. at 11
