    “f) Conclusion – Initial Fintiv Analysis We have considered the circumstances and facts before us in view of the first five Fintiv factors. Because our analysis is fact driven, no single factor is determinative of our conclusion. Considering these five Fintiv factors, we determine that they favor a discretionary denial. 2. Assessment of the Compelling Merits As we have found that the first five Fintiv factors favor discretionary denial, we proceed to assess whether the record shows that Petitioner has presented a compelling unpatentability challenge.” slip op. at 16

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

    “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. Reply 2) and contrary to Patent Owner’s construction, the claim language and the specification do not support limiting available capacity to a single RRU, or similarly, limiting the scope of “load percentage” to a load consumed by a remote radio unit divided by the assigned available capacity for that remote radio unit.6” slip op. at 13

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

    “The question of whether the prior art references are in the same field of endeavor is merely a threshold issue that must be satisfied before an obviousness determination can be made. See K-Tec, Inc. v. Vita-Mix, Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either in the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). In other words, once it is determined that the prior art is analogous to the claimed invention, it is then necessary to show that it would have been obvious for the skilled artisan to select and combine the teachings of the prior art in the manner claimed. Thus, we agree with Patent Owner that the Petition needs to set forth specific reasoning as to why an ordinarily skilled artisan would have been motivated to combine these references even if they are in the same or similar fields. Prelim. Resp. 31. Petitioner fails to do so on this record. The absence of such reasoning is particularly noteworthy here in view of Ma’s numerous teachings which appear to discredit the “passive” method of pulling the composite strand from the extruder as recited in claim 4, which is challenged in each of Grounds 2 and 3. Patent Owner identifies no fewer than eight disclosures within Ma that seemingly disparage the passive “pulling” method and discuss benefits of the active “pushing” method. Prelim. Resp. 16–19 (citing Ex. 1007, 53, 95–96, 98–107, 143–147, 149, 167–168).

Prelim. Resp. 22–23. As Patent Owner correctly observes (id.), Petitioner’s general assertion that “Lipsker discloses that combinations of disclosed embodiments and features are possible and proper” (Pet. 20) does not constitute a reasoned explanation regarding why the skilled artisan would have combined Lipsker’s precoating and non-precoating actuator embodiments to arrive at the claimed subject matter. Moreover, Dr. Rosen’s declaration testimony on this point is entitled to little to no weight as it merely parrots the Petition.

    “Ma distinguishes between these two methods, noting that with the “active” method, “the forming quality of a previous layer does not influence the forming of the current layer,” while with the “passive” method, “the quality of a previous layer has a profound effect on the forming quality of the current layer.” Ex. 1007, 53. Ma sets forth other problems with using the “passive” method. See, e.g., id. at 95–96, 98–107, 143, 145–147, 149. For example, Ma teaches that during deposition using the “passive” method, “it is possible to make a big error, especially when the nozzle makes a big-angle turn” (id. at 98), and that “[a] toolpath error could be generated if an anchoring point is not formed properly” when using the “passive” method (id. at 143). Ma also discloses that forming speed is an issue with the “passive” method, (id. at 146), but discloses “[o]ne of the advantages [of the ‘active’ method] is that the forming speed is not limited by the solidification condition of the towpreg during the forming process” (id. at 168). 2. Analysis Claim 1 recites, inter alia, “moving the nozzle away from the anchor during discharging to pull the path of the composite material out of the nozzle.” Ex. 1001, 10:61–63. Petitioner contends that Ma teaches this limitation because “Ma discloses that ‘when the object moves relative to the nozzle during the forming process, the towpreg is pulled out by the object instead of being pushed out by nozzle pressure” and “the anchor points are used to pull the towpreg (‘the path of the composite material’) out of the nozzle during discharging.” Pet. 33 (citing Ex. 1007, 38, 72)(emphasis omitted). controlled layer manufacturing: an “active” method that pushes the composite material from an extruder’s orifice, and a self-anchoring or “passive” method, wherein the composite material is pulled out by the object. Ex. 1007, 7–8, 52–54. Here, Petitioner relies on Ma’s disclosures relating to the passive method. Petitioner, however, fails to provide a persuasive explanation as to why a POSITA would have selected Ma’s passive pulling method over Ma’s active pushing method for further development or improvement. Petitioner’s failure to do so is particularly noteworthy here, because Ma includes numerous teachings against the passive method of pulling the composite material through the nozzle. Indeed, Patent Owner identifies no fewer than eight disclosures within Ma that seemingly disparage the passive pulling method and discuss the benefits of the active pushing method. Prelim. Resp. 7–10 (citing Ex. 1007, 53, 95– 96, 98–107, 143–147, 149, 167–168). We also agree with Patent Owner that Petitioner has not sufficiently explained why the ordinarily skilled artisan would have combined Ma’s active and passive methods, much less with a reasonable expectation of successfully arriving at the subject matter of claim 1. Id. at 11–14. In the absence of any explanation from Petitioner, we are not persuaded that a POSITA would have ignored Ma’s teachings against the passive pulling method and selected Ma’s pulling method over Ma’s active pushing method for further development and improvement. Accordingly, Petitioner has not demonstrated a reasonable likelihood that claim 1 would have been obvious over Ma.” slip op. at 8

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

(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.

So you don't just slap it together without worrying about what connects to what. On the other hand, the putting together of the -- in Bertin, he describes the putting together of these chips and how that can be done in detail.

They’re all done by the process that he gives an example of.
