      “Accordingly, based on this preliminary record, we find Patent Owner’s assessment of “internet web browsing software development, web connectivity software development, or networking software development” to be overly narrow in view of the asserted prior art that describes in large measure requesting and receiving web pages from web servers. Thus, we find that Petitioner’s assessment of “software development and/or web-based software” more appropriate for purposes of institution on this limited record. We also agree with Petitioner that additional education could have substituted for professional experience, and significant work experience could have substituted for formal education. For the purpose of this decision, for these reasons, we find that a person of ordinary skill in the art would have had (1) at least a bachelor’s a similar field, and (2) at least two years of work experience in software development and/or web-based software. We apply that level of ordinary skill in this decision. Our decision, however, would not change, however, if we had applied Patent Owner’s proposed level of ordinary skill.” slip op. at 11

      “Accordingly, there is evidence to consider in making a determination whether Dr. Lieberman possesses the requisite ordinary level of skill. We, however, need not make such a determination for purposes of this decision because it has not been necessary for us to rely on Dr. Lieberman’s declaration in this decision. “No rule requires a Petition to be accompanied by any declaration, let alone one from an expert guiding the Board as to how it should read prior art.” Belden Inc. v. Berk–Tek LLC, 805 F.3d 1064, 1079 (Fed. Cir. 2015). “[E]xpert testimony is not required when the references and the invention are easily understandable.” Id. (quoting Wyers v.

Here, the invention and prior art are presented in high-level functional terms and are easily understandable, as we indicated previously in Section II.A and as shown by our discussion of the invention and prior art throughout this decision. To determine that the Petition met the institution threshold of showing “a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition,” we have not relied on Dr. Lieberman’s declaration testimony.

      “In this case, Patent Owner’s assertion that its proposed construction is “consistent with the specification” fails to articulate or apply the proper standard. For example, any interpretation whose scope is equal to or narrower than a proper construction would logically be consistent with that proper construction. Thus, Patent Owner could only establish that its proposed interpretation is equal to or narrower in scope than the proper interpretation. Comparing the claims to prior art using a claim construction potentially narrower than what is claimed would not be a fruitful exercise because the claim could read on the prior art but not on the unduly narrow interpretation. Cf. Brown v. 3M, 265 F.3d 1349, 1351 (Fed. Cir. 2001) (holding that a broad claim is anticipated by any narrow disclosure falling within the broad claim). Patent Owner’s assertion that its proposed construction is consistent with examples in the specification is also not persuasive, and no more persuasive than its prior implication that its proposed construction is not inconsistent with the specification. i4i Ltd. P’ship v. Microsoft Corp., 598 F.3d 831, 843–44 (Fed. Cir. 2010) (“[A] claim is not limited to the embodiments described in the specification unless the patentee has demonstrated a clear intention to limit the claim’s scope with words or expressions of manifest exclusion or restriction.” (internal quotation omitted)). Similar to the situation in i4i, Patent Owner here has failed to explain how the claim is clearly limited to the examples in the specification. Instead, we construe “information of object” to be an identification of the object to be studied in the ultrasound examination, based on its plain language in the context of the claimed ultrasound device. We are not apprised of any language, on this record, in the ’157 patent or prosecution history that otherwise constrains what types of “object” would be inspected by the claimed device. For example, there is no indication that the machine is less capable than other ultrasound machines in a way that limits its use to examinations of certain things in a body such as a liver or a heart, but not simpler things in a body such as blood vessels or more complex things such as a fetus. Accordingly, we see no reason to constrain “object” to something other than those things in a body that a person of ordinary skill in the art would investigate during an ultrasound examination.” slip op. at 7

Patent Owner does not offer any claim constructions, but does challenge Petitioner’s choice not to offer any claim constructions, and suggests that we should deny the Petition on that basis. Prelim.

First, we note that the parties have not offered competing claim constructions, such that there is no specific claim construction issue between the parties at this time. Second, we note that we consider Petitioner’s interpretation of the claims sufficiently clear based on their application of the claims on the art.

      “Turning to the claim language, limitation vii recites “reconfiguring each remote radio unit by: determining a load percentage for each remote radio unit.” Claim 1 simply does not specify how to determine the load percentage for each remote radio unit and “load percentage” is a broad term. Stated differently, claim 1 does not specify the numerator or denominator to be used in determining the load percentage, but the parties agree that the numerator is the amount of load used in an RRU, as indicated above. On this preliminary record, Petitioner’s interpretation of “available capacity” as including “a single radio, a group of radios or the entire DAS system, [able to] be determined using throughput, number of connections, number of users, number of carriers, or power,” is sufficient for purposes of institution. See Pet. Reply 3 (citing Ex. 1005, 4:24–27; 5:13–15; 6:1–4; Ex. 1003 ¶¶ 104–06). On this preliminary record, as Petitioner argues (Pet.

Patent Owner asserts that [a] person of ordinary skill in the art (“POSITA”) around December 5, 2001 (the earliest effective filing date of the ’226 Patent) would have had a Bachelor’s degree in Electrical Engineering or a related field, and either (1) two or more years of industry experience; and/or (2) an advanced degree in Electrical Engineering or related field. PO Resp. 10 (citing Ex. 2006 ¶ 25). As we did in the Decision on Institution, we adopt Petitioner’s proposed level of ordinary skill in the art, which comports with the teachings of the ’226 patent and the asserted prior art. See Dec. on Inst. 21. Patent Owner’s proposed level overlaps substantially with Petitioner’s proposed level. Even if we adopted Patent Owner’s proposed level, the outcome would remain the same.

      “Both of these limitations listed above recite “means” and further recite a function, thus creating a presumption that 35 U.S.C. § 112, ¶ 6 applies. See 35 U.S.C. § 112, ¶ 6 (“An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.”); see also Williamson v.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

      “Patent Owner, in focusing on this portion of the ’226 patent disclosure, does not adequately explain why buffer cells and configuration memory cells must be included in the proper construction of “wide configuration data port,” and seeks to import a functional description of the use of a wide configuration data port (“that allows parallel updating of logic cells in a programmable array through use of buffer cells”) into the claim construction. PO Resp. 15–17; PO Sur-reply 2–4. While the discussion in the ’226 patent describes an example of a wide configuration data port used in a specific way that aligns with Patent Owner’s proposal (Ex. 1001, 4:45– 59), other examples of the use of a wide configuration data port are included (id. at 4:59–65), and therefore we do not agree that one of ordinary skill would understand this use to be part of the construction of the term. We agree with Petitioner that the proper construction of the term does not require buffer cells. See Pet. Reply 4–6. Rather, we note that the specification of the ’226 patent contrasts loading of data to an FPGA in a byte serial fashion through a narrow port, which “results in [] long reconfiguration times,” with the use of a wide configuration data port, and therefore we determine that one of ordinary skill would understand the wide configuration data port, in contrast to the byte serial “relatively narrow” port, to include parallel connections between cells in the dies. See Ex. 1001, 4:3– 9. This additionally is consistent with certain arguments by Patent Owner, for example in the Patent Owner’s Response, which opens with a discussion of the “innovative” processor’s arrangement of die-area contacts, such as through-silicon vias, “into a wide configuration data port” and we find that description more consistent with the proper construction of this term. PO Resp. 1–2; see also PO Sur-reply 2–3 (“Arbor’s experts have been consistent that the word ‘wide’ in this term requires a sufficient number, and appropriate arrangement, of connections between the memory die and the programmable array to permit parallel updating of the array.”)” slip op. at 15

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Decided for petitioner

      “While corresponding structure need not include all things necessary to enable the claimed invention to work, it must include all structure that actually performs the recited function.” Default Proof Credit Card Sys. Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1298 (Fed. Cir. 2005). Conversely, structural features that do not actually perform the recited function do not constitute corresponding structure and thus do not serve as claim limitations. Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308–09, (Fed. Cir. 1998); see B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed. Cir. 1997) (“[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.”). Patent Owner’s arguments regarding buffer cells connected with memory configuration cells using die-area interconnections requires that the buffer cells be located on a different die than the memory configuration cells, but the ’226 patent discloses only that “[t]he buffer cells 88 are preferably a portion of the memory die 66” and not that they always are on the memory die, and also that the significantly increased number of connections to the cache memory die may allow the cache memory die to replace configuration bit storage on the FPGA die. Ex. 1001, 4:50–54, 4:59–63. Thus, we decline to require in the corresponding structure that buffer cells or configuration memory are included on any die element. Rather, we find that what is disclosed as actually performing the recited function of “reconfiguring the programmable array within one clock cycle” is “a wide configuration data port and contact points formed throughout the area of the first integrated circuit die element and another integrated circuit die element.” The support for this is found in the ’226 patent’s comparison of the long reconfiguration times through a narrow port (Ex. 1001, 4:3–9) with the time to reconfigure through a wide configuration data port with a significantly increased number of connections (id. at 4:45– 65), and the implementation of this in a module that has multiple dies “which have a number of corresponding contact points, or holes, 70 formed throughout the area of the [die] package” (id. at 4:9–20). The use of a wide configuration data port, as per our construction, implicates two die elements. This was reflected in our preliminary claim construction, for which the corresponding structure described “contact points distributed through the first integrated circuit die element and the third integrated circuit die element.” Dec. on Inst. 29. As the function is “reconfiguring the programmable array within one clock cycle,” one of the die elements is the first integrated circuit die element, which includes the programmable array. slip op. at 19

      “articulated reasoning to support a conclusion of obviousness. PO Resp. 2–3, 23–39; PO Sur-reply 10–14. (i) Alleged Misrepresentation of Chiricescu First, Patent Owner contends that “Petitioner misrepresents Chiricescu to allege motivation to combine Zavracky and Chiricescu.” PO Resp. 24–25 (Section VI.A.3(a)). Patent Owner specifically asserts that Chiricescu does not employ Zavracky’s principles, does not utilize Zavracky’s principles to improve reconfiguration time, and “does not employ Zavracky’s die-area vertical interconnections to connect a memory die to an FPGA, and no die-area vertical is involved whatsoever in reconfiguring Chiricescu’s FPGA.” PO Resp. 24 (citing Pet. 18–19, Ex. 1004, 232 (Exhibit page 1), 234 (Exhibit page 3); Ex. 2011 ¶ 6117). The record does not support this line of argument. Chiricescu’s Abstract indicates the paper describes “[t]he architecture of a 3-dimensional FPGA for reconfigurable computing machines” and “is based on a novel 3-D circuit technology developed at Northeastern University.” Ex. 1004, 232 (Abstract); see Pet.
