“Based on Petitioner’s arguments and evidence, we are persuaded that Petitioner has shown sufficiently for purposes of this Decision that Zhang teaches the recited “digitizing” step of element 1C. For example, Zhang teaches that its ADC 220 “converts the down-converted multi-channel analog RF signal to a multi-channel digital RF signal.” Ex. 1013 ¶ 27 (cited by Pet. 22). Zhang explains that “many modifications, variations, alternatives, and equivalents . . . are intended to be within the scope of [its] invention,” and gives the example that “the RF channels need not be contiguous.” Id. ¶ 48 (cited by Pet. 22). We agree with Petitioner that Zhang’s example teaches or suggests that the RF channels may be contiguous. Zhang further describes “demultiplex[ing] the multi-channel digital RF signal into separate digital RF channels C1 to Cn,” which “contain content channels that are selected or used by a subscriber.” Id. ¶ 28 (cited by Pet. 22). Zhang describes filtering the RF channels so that “only the target RF channel passes.” Id. ¶ 32 (cited by Pet. 23). In addition, Zhang describes “select[ing] one or more of the RF channels D1 to Dm from one or more of the digital RF channels C1 to Cn,” where “only the selected channels are later demodulated unlike the systems using RF tuners which demodulate all of the RF channels.” Id. ¶ 28.” slip op. at 15

In particular, Patent Owner argues the Petition asserts “at a minimum 40 separate grounds (grounds ‘A’ through ‘NN’), involving eight separate references, challenging claims 1– 20” and “[t]his ‘voluminous and excessive’ number of grounds is an independently sufficient reason to deny institution.” Id. (citing Adaptics, 18). Petitioner challenges claims 1–20. Pet. 9. Fourteen claims, specifically claims 1–7, 10, 12, 14, 15, and 18–20, are challenged on the basis of four grounds, specifically Grounds A–D. Id.

In view of the above, as well as the complexity of the technology and detailed nature of certain of Petitioner’s arguments, we decline to exercise discretion and deny institution on the basis of the number of grounds asserted.” slip op. at 42

“bandwidth, we agree with Patent Owner that this contention is unsubstantiated. Although there is sufficient evidence that Grube’s common bit-loading scheme improves upon and benefits infrastructures utilizing telephone lines, Petitioner provides no basis, or minimal at best, to bridge those advantages obtained in the context of Grube’s system to Carhart’s BCN. The evidence Petitioner cites from Grube and Dr. Williams (Ex. 1010, 2:48–3:17, 3:34–42, 4:18–26, 6:54–67, 7:13–8:14, 14:33–46, 34:45– 52, 57:29–38, Fig. 8; Ex. 1004 ¶¶ 92–111) either describes how Grube’s bitloading scheme works in an infrastructure utilizing telephone lines or it represents that the bit-loading scheme is able to satisfy the need for a one-tomany and/or many-to-one communication system within an infrastructure that utilizes existing telephone wires. Dr. Williams’s testimony provides little, if any, persuasive information to bridge the gap between how Grube’s bit-loading scheme’s usefulness within a telephone line infrastructure translates to a skilled artisan into adding similar value within a BCN infrastructure; instead, Dr. Williams largely mirrors the naked assertions Petitioner makes and cites to the same evidence without further substantive reasoning. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Likewise, no underlying support or reasoning from either Petitioner or Dr. Williams is provided to substantiate the claim that “Grube represents a suitable, known technique for orchestrating digital communication between a central unit and multiple remote units in networks like Carhart’s” (Pet. 16). Grube suggest that its technique eliminates high data rate transmission path requirements to expand the usefulness and areas in which communications systems may be established. Ex. 1010, 57:29–38. Petitioner offers no basis for us to determine Grube’s technique for eliminating high data rate transmission path requirements would have been a known technique by skilled artisans for orchestrating digital communication between nodes within a network like Carhart’s that necessarily depend on the high data rate transmission paths that a BCN provides. Left unfulfilled is any clear explanation for why or how Grube’s bit- loading scheme would have actually improved or benefited Carhart’s system, which Petitioner admits already teaches a network with a centralized computer that uses existing coaxial cables to communicate with remote stations (Pet. 10). For example, Petitioner does not identify a single known shortcoming with Carhart’s one-to-many and/or many-to-one communication system infrastructure that a skilled artisan would recognize may be overcome with Grube’s bit-loading scheme. To the contrary, as Patent Owner notes, rather than needing a technique Grube teaches to address the lack of “adequate bandwidth” provided by telephone wires (Ex. 1010, 2:1–3), Carhart teaches that its BCN provides excess unused bandwidth (Ex. 1009, 8:36–38). Nor does Petitioner explain why or how a skilled artisan would have viewed Grube’s bit-loading scheme to be superior to the schemes Carhart utilizes to form a multi-casting infrastructure. Moreover, Petitioner’s admission Carhart teaches that teaches a BCN with a centralized computer that communicates with remote stations, further weakens Petitioner’s position because it shows Carhart’s infrastructure already accomplishes the same goal that Petition proposes a skilled artisan would have sought to achieve through the proposed modification.

“The last point we make about Petitioner’s reasoning is that it lacks any substantive support for why a skilled artisan would have chosen to configure Carhart’s node to have the functionality Grube describes for its primary site. Here again, Petitioner simply concludes that a skilled artisan would have found it obvious to have Carhart’s nodes act as Grube’s primary site without any evidence that such a correlation was known by skilled artisans or any analysis regarding the roles Carhart’s nodes and Grube’s primary site play within their respective infrastructures that would have led to that choice. Pet. 20–21. We are mindful that “[c]are must be taken to avoid hindsight reconstruction by using ‘the patent in suit as a guide through the maze of prior art references, combining the right references in the right way so as to achieve the result of the claims in suit.’” Grain Processing Corp. v. American–Maize Prods. Co., 840 F.2d 902, 907 (Fed.Cir.1988) (quoting Orthopedic Equip. Co. v. United States, 702 F.2d 1005, 1012 (Fed. Cir. 1983)). Petitioner’s failure to provide any clear explanation backed by supporting evidence for why a skilled artisan would have selected Carhart’s nodes to modify and perform as the primary site when implementing Grube’s bit-loading scheme suggests Petitioner improperly relied on hindsight reasoning to piece together elements to arrive at the claimed invention. For the above reasons, we are not persuaded that Petitioner has shown with sufficient particularity why it would have been obvious to modify a node in Carhart, in view of Grube, to transmit a probe signal to the other respective nodes and determine a common bit-loading modulation scheme from the various bit-loading modulation schemes determined and provided by each of the other respective nodes that received a probe signal. And as a result, we find Petitioner has not demonstrated a reasonable likelihood of proving that one of ordinary skill in the art would have been motivated to combine Carhart and Grube as proposed. This failing undermines Petitioner’s showing as to independent claims 1–3 for all grounds.” slip op. at 28
