      “The level of skill is uncontested. Patent Owner adopts the level of skill identified by Petitioner as: [at] the time of the alleged invention in 2018, a POSITA[2] would have had a B.S. degree in mechanical or petroleum engineering or a similar technical discipline, with at least five years of experience in oil or gas well drilling, completion, and/or subsurface production operations or in technical support of such operations including at least some experience in unconsolidated formations utilizing sand control methods and means.

      “on embodiments of Yeh with concentric sand screens having nine shunt tubes (six transport tubes and three packing tubes) (Yeh Figures 4A–B) and eccentric sand screens with four shunt tubes (two transport tubes and two packing tubes) (Yeh Figures 8A, 8C). See Pet. 32–37, 39, 41–43. Yet, Petitioner’s reasoning as to why “a higher-pressure shunt tube assembly necessitated greater wall thickness” rests on an unspoken one to one comparison between the shunt tubes of the different systems. See id.; see also Ex. 1003 ¶¶ 291–297 (Petitioner’s declarant comparing possible transport tubes of different pressure regions without considering or addressing any difference in the number of transport tubes). However, the embodiments relied on by Petitioner have different numbers of shunt tubes, and thus the greater wall thickness does not appear to be “necessitated” in the way inferred by Petitioner. Further, Petitioner’s analysis would seem to be most appropriate when comparing two concentric sand screens for different pressure regions, or two eccentric sand screens for different pressure regions. relies on Yeh’s teachings related to a horizontal well bore of 5000 feet for the “concentric screen → crossover tool → eccentric screen” arrangement, as well as, for why the concentric screen needs to be rated for a high pressure. Pet. 32–37, 39, 41–43. Petitioner also refers to these features for why one of skill in the art would combine the teachings of Yeh and Yeh2. Id. at 32. However, on cross-examination, Petitioner’s declarant agreed that it is concentric sand screens having a 6x3 shunt tube design that would provide the noted benefits of being rated for a higher pressure and being more robust (as relied on in the Petition), as compared to eccentric sand screens. Ex. 2013, 42:20–43:8; Sur-reply 4–5. This also exposes another issue with Petitioner’s arguments. Though Petitioner identifies that one of skill in the art would be aware that material choice, wall thickness, and pipe diameter all impact burst pressure of a pipe (Pet. 42 (citing Ex. 1017, 24 (Equation (14))), the Petition essentially ignores the fact that the claims do not require a single pipe in isolation. The claims require two shunt tube assemblies, each surrounding a base pipe within a wellbore. It is uncontested that a wellbore provides a confined space for such a system and thus any change in wall thickness of one pipe can result in a significant impact in the function of the other pipes. We find the testimony of Petitioner’s declarant (see, e.g., Ex. 1003 ¶¶ 290–297) unpersuasive when discussing wall thickness because it focusses on basic considerations of a standalone pipe, without sufficient consideration of the claimed completion assembly with its required pipe and tube structure. PO Resp. 20–26.” slip op. at 17

      “In response to Patent Owner’s argument concerning Yeh’s embodiments relied on in the Petition, Petitioner argues for the first time that Patent Owner’s declarant “conceded, Yeh discloses that both concentric and 47:19–48:21). Petitioner does not provide a citation to Yeh or a citation to where the Petition relies on the same number of shunt tubes between concentric and eccentric screens. The deposition cited by Petitioner discusses Yeh at column 16, lines 26 through 35. However, the Petition does not cite or rely on these teachings of Yeh. Thus, we decline to consider this late argument.4 See 35 U.S.C. § 312(a)(3) (requiring the petition to identify “with particularity . . . the grounds on which the challenge to each claim is based, and the evidence that supports the grounds”); 37 C.F.R. § 42.104(b)(5).” slip op. at 18

      “Thus, we agree with Petitioner that the combination of Yeh and Yeh2 teaches determining the shunt tube system operating pressures associated with the distal end of the production zone, but also more generally, determining the operating pressures along the entire production zone. With this knowledge of the system operating pressures, Petitioner argues that one of skill in the art would have selected eccentric screens for the distal end of the production zone “at any point at which the slurry pressure dropped below the pressure capacity of the eccentric screen shunt tubes.” Pet. 66 (citing Ex. 1005, 30:16–20; Ex. 1003 ¶ 388). In other words, knowing that the pressure decreases as you approach the toe, Yeh’s low-pressure rated eccentric screens could be used from some point prior to and covering the toe. determined pressure.” PO Resp. 37–38. We disagree. As discussed above, the record supports Petitioner’s position that one of skill in the art would have “understood the need to determine the shunt tube system operating pressure throughout the horizontal wellbore.” Ex. 1003 ¶ 383; see also Pet. 64–65. We find convincing Petitioner’s argument that one of skill with this understanding of the system pressures would select a shunt tube system rated to not only address the distal end, but also to address the needs of the adjacent region, so long as the pressure rating supported such a selection. See Pet. 65–67; Ex. 1003 ¶¶ 385–388.” slip op. at 22

      “arguments, we agree with Patent Owner’s proposed construction that requires the server to conduct a compatibility check. We start with the express claim language. Claim 10 recites: determining, by the server, applicable settings for the selected vehicle, the applicable settings being settings that are preferred to be set as identified from the user profile and are compatible with settings that are settable in the selected vehicle. Ex. 1001, 33:10–14 (emphases added). The express claim language requires that the server determine applicable settings. Those applicable settings, determined by the server, must also be compatible with vehicle settings. As such, the plain and ordinary meaning of the claim language expressly requires that the server make a determination of applicable settings that are defined as being compatible with vehicle settings.” slip op. at 14

      “Petitioner contends that a person of ordinary skill in the art (“POSITA”) at the time of the invention of the ’268 patent “would have had at least a Bachelor’s degree in electrical engineering, computer science, or closely related field, with at least two-to-four-years-experience in cloud services for settings customization, or a Master’s degree in electrical engineering, computer science, or equivalent.” Pet. 12 (citing Ex. 1009 ¶ 82).

      “However, contrary to Dr. Almeroth’s testimony and Petitioner’s position, Xiao’s server already does not attempt to command vehicles to do things they cannot do. Xiao teaches that server 118 generates commands for command codes that exist and are settable in the vehicle. Ex. 1010 ¶¶ 102– 103. As such, if there is no corresponding automobile setting, then Xiao’s server would not list those command codes for retrieval and would not send a command based on that retrieved command code to control the automobile systems to achieve the operator’s desired settings because that command code is not in the database. Our understanding of Xiao is further supported by Dr. Almeroth’s testimony: By listing them in the table of automobile command code information 606, Xiao shows that there are particular settings compatible with particular automobiles and particular desired settings. Thus, Xiao demonstrates the necessarily present characteristic that certain settings (e.g., commands) are compatible with certain automobiles. Ex. 1009 ¶ 96 (emphases added). We note that Dr. Malek further explains “the nonsensical result achieved by the combination would be that Xiao’s server, at best, in response to the command request issued by the operator, could ‘look up’ a command code to apply a vehicle-specific setting to that automobile 112, only to find that there is ‘none.’” We agree with Dr. Malek that there is a “None” command code in Xiao’s database when Xiao’s database already stores settings that are known to be settable in a specific vehicle per the operator’s preferences. Ex. 2011 ¶ 135. Thus, based on the complete record, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Xiao in combination with Hayashi render claim 10 obvious.” slip op. at 79

Petitioner and Dr. Almeroth both acknowledge that Xiao discloses operators on the same account. Pet. 40–41; Ex. 1009 ¶ 170. But Petitioner and Dr. Almeroth do not explain sufficiently how Xiao discloses these operators have sub-user accounts. Petitioner further contends Xiao discloses plurality of accounts. Pet. Reply 18–19 (citing Ex. 1024, 33:1–44:10, 45:22–46:2); Ex. 1010 ¶ 65.

      “the structure and function of the 2006 904 Operating Manual’s product holder and Lindee’s grippers are similar in that they serve to grip food product and guide it to the slicing station. See, e.g., Ex. 1005, 23; Ex. 1006, 18:20–35, Fig. 7A. The two devices differ in their actuation—the 2006 904 Operating Manual uses a ball screw spindle actuator to drive the product holder along the feed path, whereas Lindee uses a timing belt 334 to drive its grippers 151 along the feed path. Ex. 1005, 273–274; Ex. 1006, 18:33–34, Fig. 7A. However, Petitioner presented evidence that “unlike ball screws, belt drives do not require periodic lubrication with grease or exhibit backlash when they change direction.” Ex. 1003 ¶ 160. In addition, Petitioner demonstrates that a POSA at the time would have understood that conveyor belts like Lindee’s can be easily cleaned. Ex. 1051 ¶¶ 50–54. Petitioner further asserted that conveyor belts are easy to maintain at low cost. Id. citing ¶¶ 55–58. We agree with Petitioner that, at least for some scenarios, including those that Petitioner specifies, a POSA would have seen that there were advantages to using Lindee’s timing belt rather than the 2006 904 Operating Manual’s ball-screw to drive food article grippers.

    • BurdenDecided for petitioner

      “We decline to dismiss or terminate this proceeding on this basis. Patent Owner has not provided us any controlling authority that prevents a petitioner from advancing one construction in the District Court Litigation as an infringement defendant and a different construction as a Petitioner before the Board. Further, we note that 37 C.F.R. § 42.100(b) provides that the Board shall use the same claim construction standard as the courts, not that the Board shall use the same construction. The Board does, however, “consider[]” prior claim constructions by a district court. See 37 C.F.R. § 42.100(b). In any event, the related District Court Litigation here has been stayed; there is no court construction before us, only the parties’ proposals. Sur-sur-sur-reply 5; see Tr. 67:22–68:4 (“JUDGE IPPOLITO: And the related district court proceeding, by my recollection, has been stayed without the claim construction hearing; is that correct? MR. FRANKLIN: That’s correct. It was stayed without a claim construction hearing, without a claim construction order, without a tentative claim construction order, and for that matter, without the briefing on claim construction having been completed.”). Thus, to the extent that Patent Owner contends there is danger of inconsistent results, that danger is mitigated by the stay.” slip op. at 15

      “problems encountered in the art, the prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field. Custom Accessories, Inc. v. Jeffrey-Allan Indus. Inc., 807 F.2d 955, 962 (Fed. Cir. 1986); Orthopedic Equip. Co. v. United States, 702 F.2d 1005, 1011 (Fed. Cir. 1983). Petitioner contends that a person of ordinary skill in that art “would have had a bachelor’s degree in mechanical engineering or an equivalent field, plus at least two years of experience working in the field of mechanical design and product testing.” Pet. 7 (citing Ex. 1007 ¶¶ 34–36). Patent Owner does not dispute this level of skill. See generally PO Resp. For purposes of this Decision, we adopt Petitioner’s proposal as reasonable and consistent with the prior art. See Okajima v.

      “We begin with the claim language. Patent Owner’s proposed construction proffers language that is not expressly recited in the claim. In particular, claim 1 does not recite a “spring.” Ex. 1001, 10:34–56. Nor does a “spring” appear in the other limitations of any claims. Thus, the express claim language does not require more than spring action. Our reading of claim 1 is consistent with the ’413 patent’s Specification that describes the operation of a spring action force clamping member, but does not describe a clamping member with a spring that specifically provides the spring force. In other words, while we agree that the spring action clamping member is recited as providing “spring action,” we are, however, not persuaded that this limitation requires a “spring.” As noted in the Specification, Figures 2 and 3 of the ’413 patent teach that an outwardly directed spring force may be created by U-shaped sections 58 of the spring action clamping member. Ex. 1001, 5:44–47. The ’413 patent further discloses that “[t]he degree of outwardly directed spring force may be varied by varying the bend radius of the U-shaped sections 58.” Id. at 5:47–49. As such, the outwardly directed spring action force is disclosed in these sections as being generated by U-shaped sections of the spring action clamping member interconnecting with walls 60 shown in Figure 2. Id. at 5:44–47. The Specification does not disclose a specific type of spring structure, nor does it define the U-shaped sections of the spring action clamping member interconnecting with walls 60 as a “spring.”” slip op. at 21

      “(3) Discussion Based on the complete record, we are persuaded by Petitioner that Sprague ’905 teaches these limitations. To start, as discussed in our claim construction above, we have not adopted Patent Owner’s proposed construction that requires a “spring action clamping member” to include a “spring.” See supra Sect. II.E. Rather, we have construed the plain and ordinary meaning of “spring action clamping member” to be that the “spring action clamping member provides a spring action force.” In this way, we are not persuaded that claim 1 requires a “spring” that requires material and physical dimensions according to Patent Owner’s proposed definition. See Ex. 2022 ¶ 27. This is particularly so when the express claim term is broader, requiring only a spring action force, and the Specification of the ’413 patent does not support Patent Owner’s narrower construction. With this construction in mind, we find Sprague ’905 teaches these contested limitations. In particular, Sprague ’905 discloses that the tightening of screw 206 forces clamp member 204 to move in the driven direction of arrow A shown in Figure 12. Ex. 1003, 6:50–51. Sprague ’905 teaches this forced movement brings clamp member 204 into contact with housing 202 at inclined surfaces that cause arms 208, 210 to move toward each other and “provide clamping force.” Id. at 6:51–57. Moreover, Sprague ’905 further discloses that the rail system is “easier to assemble and disassemble” and “facilitates easy field maintenance and replacement.” Id. at 2:39–42, 2:45–46. We find that this disclosure is consistent with the notion that screw 206 can be untightened to release clamp member 204 and move arms 208, 210 away from each other.” slip op. at 39

      “Petitioner states that all claim terms should be accorded their plain and ordinary meanings (Pet. 11), but the parties address the meanings of “switch/switch element” and “bi-directional” in subsequent briefing, among other terms. PO Resp. 28–39; Reply 1–4; Sur-Reply 3–5. The parties’ dispute regarding these claim terms does not affect our analysis below, and we, thus, determine that it is unnecessary to expressly interpret any claim terms for the purposes of this Decision.

      “1. Reasons to Combine Ting and Pani Petitioner contends both Ting and Pani are directed to FPGAs, have a common inventor, and have a common assignee. Pet. 128 (citing Ex. 1002 ¶ 228). Further Petitioner contends “Pani even indicates that it is meant to be combined with the disclosures of Ting” because Pani’s specification twice refers to Ting as examples of compatible disclosures. Pet. 128 (citing Ex. 1006, 5:17–20, 8:31–35; Ex. 1002 ¶ 228). According to Petitioner, Ting disclos[ing[ improvements over a conventional bus system because Pani’s programmable connections between multiple cells without permanent wiring increases the versatility of a programmable logic device.” Pet. 129 (citing Ex. 1006, 2:19–33, 5:6–20; Ex. 1006 ¶ 230). Further, Petitioner states that “[i]t would have been obvious to a POSITA to take the configuration disclosed by Ting, and apply the slight variation disclosed by Pani, in order to create an FPGA that could perform different logic functions.” Pet. 129 (citing Ex. 1002 ¶ 231). Based on the evidence of record, including the testimony of Dr. Sechen, we determine Petitioner has articulated adequate reasons for combining the teachings of Ting and Pani. In particular, we agree with Petitioner that the references describe complimentary technology and that Pani provides an express suggestion to combine its teachings with Ting’s teachings.” slip op. at 16

    • Skill levelDecided for petitioner

      “III. LEVEL OF ORDINARY SKILL IN THE ART In determining the level of skill in the art, we consider the “type of problems encountered in the art, the prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field.” Custom Accessories, Inc. v. Jeffrey-Allan Indus. Inc., 807 F.2d 955, 962 (Fed. Cir. 1986); Orthopedic Equip. Co. v. United States, 702 F.2d 1005, 1011 (Fed. Cir. 1983). Petitioner contends that a person of ordinary skill in the art at the time of the invention of the ’619 patent would have had the following education and experience: at least (1) a master’s degree in electrical engineering, computer science, or a related degree, and at least 3-5 years of experience in computer architecture and cache memory design; or (2) a bachelor’s degree in electrical engineering, computer science, or a related degree, and at least 5-6 years of experience in computer architecture and cache memory design. Pet. 5 (citing Ex. 1002 ¶ 27). Patent Owner does not dispute this level of skill. See generally PO Resp. Based on the final record before us, including the prior art of record, we adopt Petitioner’s proposal, which is also supported by Dr. Sechen’s testimony. See Ex. 1002 ¶ 28.” slip op. at 8

      “A. “instruction cache” Each of claims 1, 21, and 29, specifically require a method or system for instruction error correction that uses “an instruction cache.” In its Petition, Petitioner does not specifically advocate for an interpretation of “instruction cache.” In our Institution Decision, we noted the importance of the meaning of the term because “Patent Owner challenges two of the prior art references (Haswell and Itou) as not disclosing an instruction cache, as claimed, arguing instead that each reference uses a main storage memory or similar.” Dec. on Inst. 21–22. In the Institution Decision, we preliminarily found that the instruction cache is a memory for the storage of instructions that are accessed and executed by the processor. Id. (citing Ex. 1001, 1:62– 64, code (57)). We also noted that lack of argument and evidence at that phase of the proceeding. Id. The parties responded by including additional argument, testimony, and evidence in the final record, which we now consider. Patent Owner argues that an “instruction cache” is distinct from main memory. PO Resp. 31–32. Patent Owner first relies on the cross-examination testimony of Dr. Sechen (Exhibit 2005), Petitioner’s expert. Id. Dr. Sechen testified during questioning that the main memory is not an instruction cache in that “it wouldn’t satisfy the normal definition of an instruction cache, which has certain features.” Id. (quoting Ex. 2005, 61:20– 62:7, 98:3–101:10). Patent Owner further argues that Dr. Sechen “also explained that the retrieval of data from an instruction cache is faster than from main memory due in part to its proximity to the processor.” Id. at 32 (quoting Ex. 2005, 166:8–18). Patent Owner further relies on the description of an “instruction cache” found in the Specification of the ’619 patent, that “[t]he instruction cache 103 is a memory for the storage of instructions 109 that are accessed and executed by the processor 106.” Id. (quoting Ex. 1001, 1:62–64). Patent Owner also relies on the testimony of its own expert, Dr. Przybylski, who testifies that “the retrieval of data from a cache is faster (and thus takes fewer instruction cycles) than retrieval from main memory,” and “[b]ecause an instruction cache only holds a subset of the contents of main memory at any given time, a cache requires tags, a tag storage, and hit/miss logic in order to autonomously determine whether the fetch of an instruction can be satisfied from the cache.” Ex. 2003 ¶¶ 65, 66; Ex. 1001, 3:19–21.” slip op. at 9

      “B. “means for detecting an error” Independent claim 29 recites “means for detecting an error in each of the instructions concurrently with the fetching of a respective one of the instructions.” Ex. 1001, 12:51–53. Petitioner contends, and we agree, that “[t]his element is interpreted under pre-AIA 35 U.S.C. §112, ¶6 because it claims ‘means for’ and then recites the function of ‘detecting an error in each of the instructions concurrently with the fetching of a respective one of the instructions.’” Pet. 38. Petitioner identifies the corresponding structure as the error correction circuitry 129. Id. (citing Ex. 1001, 7:53–55 (“error detection of the same instruction 109 is performed by the error correction circuitry 129 (FIG. 1)”). Patent Owner does not challenge this interpretation. We find Petitioner’s showing persuasive as to the interpretation of the “means for detecting an error” limitation. C. “means for generating a corrected instruction” Claim 30 recites “means for generating a corrected instruction if the error is detected in the instruction, the corrected instruction being a corrected version of the instruction.” Ex. 1001, 12:55–56. Petitioner contends, and we agree, that this element “is interpreted under pre-AIA 35 U.S.C. §112, ¶6 because it claims ‘means for’ and then recites the function of “generating a corrected instruction if the error is detected in the instruction, the corrected instruction being a corrected version of the instruction.” Pet. 40–41. Petitioner identifies the corresponding structure as the error correction logic 143 or circuit 129. Pet. 41. Petitioner relies on the ’619 patent’s disclosure of “when an error is detected ‘in either the instruction 109 or the error correction code 113, then the error correction logic 143 proceeds to generate a corrected version of the instruction 109 and its associated error correction code 113.’” Id. (citing Ex. 1001, 6:7–11; Ex. 1002 ¶ 134). Additionally, Petitioner notes that “the ’619 patent discloses that the error correction circuitry 129 (e.g., collectively) generates a corrected version of the instruction 109 and its corresponding error correction code 113. Pet. 41–42 (citing Ex. 1001, 10:1– 3; Ex. 1002 ¶ 134) (footnote omitted). Thus, according to Petitioner, “a [person of ordinary skill in the art] POSITA would understand that either the error correction logic 1292 or the error correction logic 143, which belongs to the error correction logic 129, generates the corrected instruction.” Pet. 42 (citing Ex. 1002 ¶ 134). Patent Owner does not challenge this interpretation. We find Petitioner’s showing persuasive as to the interpretation of the” slip op. at 20

Accordingly, Petitioner has shown by a preponderance of the evidence that Haswell discloses “error correction” as required by the preamble of claim 1.” slip op. at 28
