    “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.

    “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.

    “highlighted when a user selects this content source in some manner. Ex. 1001, 30:27–51. At that juncture, after a user selects the content source and it is highlighted, the content source is then associated with the first content information, “801 – CNXN,” which is displayed on the right panel of Figure 15B. See id. We do not understand the ’040 patent as requiring the display “801 – CNXN” to cause the corresponding highlighting of Live TV 1504A as suggested by Multimedia. The claim language requires the two elements “being associated with”5 one another, but it does not require that one element’s display (first content information) causes the highlighting of the other element (content source). Our view is supported by the only description of highlighting a content source found in the specification of the ’040 patent. In regard to Figure 15B, the specification describes that “global panel 1404 may include one or more sources represented by icons and text, or shortcuts, 1504A-E.” Ex. 1001, 30:27–28. The specification describes how highlighting the source is user directed: Global panel 1404 may additionally indicate a source that is selected or highlight [sic] using indicator 1512; for example, indicator 1512 may comprise a box positioned around Live TV 5 As the Federal Circuit has explained, “the plain meaning of associating relates to a mere commonality.” Apple Inc. v. Motorola, Inc., 757 F.3d 1286, 1306 (Fed. Cir. 2014), overruled by Williamson v. Citrix Online, LLC, 792 F.3d 1339 (Fed. Cir. 2015) (on unrelated grounds). 801 CNXN. Although illustrated as a box, other methods or configurations which provide for icon selection and/or identification may be used. For example, instead of a box, indicator 1512 may comprise adjusting the background of an icon and text, such as 1504A for example, such that the color, shade, or hue is different. Id. at 30:41–49 (emphasis added). Highlighting, as the specification describes, occurs when a user selects a source using indicator 1512 and that source is boxed or differentiated by color or shading. Id. The specification, in relation to Figure 15C, further describes a user moving indicator 1512 to another source such that the “the content or a preview of the content may be displayed in active content area 1408.” Id. at 32:9–17 (“For example, FIG. 15C illustrates an image or video associated with Skyfalls being displayed in content area 1408.”). Thus, the specification is clear that the highlighting function results from user selection of the source and the corresponding association of the first content information with that source flows from that user selection. See also id. at 2:30–31 (describing a purpose of the ’040 patent as “an Intelligent TV with intuitive user interfaces and with seamless user interaction capability”), 32:35–43 (“[t]he user . . . move[s] the focus box”).

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).

Level of Ordinary Skill in the Art Petitioner asserts: A person of ordinary skill in the art (i.e., a skilled artisan, or “POSITA”) at the time of the ‘791 patent’s alleged invention would have: (i) a bachelor’s degree in mechanical engineering, electrical engineering, or physics, or undergraduate training in an equivalent field, and (ii) at least two years of experience in the design and/or implementation of LED panels . . . Additional graduate education could substitute for professional experience, and significant work experience could substitute for formal education. Pet. 17–18 (citing Ex. 1002 ¶¶ 41–44).

    “and further limit either claims 1 or 12. Ex. 1001, 87:63–67, 88:17–18, 88:46–50. We have reviewed the record. Based on the evidence and argument presented, Petitioner has sufficiently shown that Kalua in view of Ordinary Skill teach and suggest each limitation in claims 10, 11, 13, 19, and 20, and has articulated sufficient reasoning, with rational underpinning, that an ordinarily skilled artisan would have combined Kalua with Ordinary Skill in the manner Petitioner proposes.
