  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner

    “Claim 1 explicitly recites “partially,” not “fully” or “completely.” On its face, “partially” appears to have its plain and ordinary meaning, i.e., not completely. The use of “partially” in the subject limitation shows or at least strongly suggests that the claimed invention contemplates at least some frequency gap to remain between the first channel and the second channel. In addition, as argued persuasively by Patent Owner, this interpretation is further supported by claim 1’s requirement of “transmitting data subcarriers occupying the first channel, the second channel, and the frequency gap in parallel to a receiver”: [T]he “transmitting” step in claim 1 requires that the frequency gap be included in the transmitted signal. Inclusion of the frequency gap in the transmitted signal necessarily requires that the frequency gap be only partially filled -- but not fully filled -- with added data subcarriers at the time of transmission, because if the frequency gap were fully filled it would no longer exist at the time of signal transmission. Prelim. Resp. 23. Petitioner offers no explanation for how the language of claim 1 itself would allow for “partially” to encompass “completely.”” slip op. at 15

Accordingly, Petitioner has not shown sufficiently for purposes of institution that Bruner anticipates independent claim 24.

This is consistent with the Specification, which explains: Users and software applications do not always refer to hosts or other resources by their numerical IP address. Instead of using numbers, they use ASCII strings called domain names. The Internet uses a Domain Name System (DNS) to convert a domain name to an IP address. Ex. 1001, 1:45–50.

Patent Owner further contends that “[t]he use of a domain name to define the virtual network in the ‘785 Patent’s claims provides more than an identifier of the virtual network or even a plain language identification of an IP address – it signifies a hierarchical structure for the virtual network that enables [certain functions].” Prelim.

Rather than explaining the “why,” the Petition’s motivation argument focuses on the purported capabilities of the resulting combination and implying, but not explicitly stating, that the combination results in the claimed subject matter; this indicates impermissible hindsight.

Cir. 2017) (“Without any explanation as to how or why the references would be combined to arrive at the claimed invention, we are left with only hindsight bias that KSR warns against.”); see KSR, 550 U.S. at 421 (2007) (“A factfinder should be aware, of course, of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning.”). “Any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning, but so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure, such a reconstruction is proper.” In re McLaughlin, 443 F.2d 1392, 1313–14 (CCPA 1971). In this case, Petitioner does not show sufficiently how or why an alleged desire to “increase efficiency, redundancy, and scalability of Lawson’s routing network” would have led the ordinarily skilled artisan specifically to the subject Mapping Limitation, but for using claim 1 as a roadmap. Indeed, as Patent Owner persuasively argues: The Petition fails to tie these generic design goals to the specific functionality that the Petition seeks to cherry-pick from Choquier and import into Lawson. Put another way, the Petition does not explain what about Choquier’s scalability, load balancing and redundancy techniques would have motivated [the skilled artisan] to have configured Lawson’s servers to “determine which server groups (node types) should receive an event update based on this server groups to event producer mapping.” Prelim. Resp. 26–27. Petitioner never identifies how Lawson’s registries of servers/consumers become the claimed gateway-kept category→node-type mapping (EX1005, 10:63–67; 12:36–43). Nor does Petitioner show that Choquier’s service map—not keyed by message category and used for CPU-based server selection—somehow supplies the missing category→node-type routing rule that controls update-message traffic through routing nodes (EX1007, 11:2–22; 12:33–36; 12:56–61). To the contrary, Choquier’s update path increases processing by replicating each update to every server in the service group (EX1007, 21:27–50), which is the opposite of the claim’s mapping-based control that limits which nodes must process a given update. Id. at 30–31. We find this context shows that Petitioner’s reasons for combining Lawson and Choquier (and Tsutsumitake) to achieve the subject Mapping Limitation lack rational underpinning, and that Petitioner’s proposed combination of teachings is based on impermissible hindsight.” slip op. at 27

    “of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197. Accordingly, we determine there is insufficient evidence to support Petitioner’s conclusory statements that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed.” slip op. at 23

    “least in part on a second message including at least one command in a second format.’” Pet. 4 (citing Ex. 1104, 168–173). The cited portion of the prosecution history shows that the applicant distinguished its claims from the prior art based on different first and second formats. The applicant argued in particular, Applicant submits that [the prior art] is completely silent with regard to “receiving, from the remote server device, a first message that includes at least one command in a first format, wherein the first message is received based at least in part on a second message including at least one command in a second format having been sent from the associated remote computing device.” In fact, [the prior art] never describes commands in different formats. . . . Ex. 1104, 170. Based on the applicant’s argument in this regard, we find that the prosecution history limits the scope of claim 1 to different first and second formats. In other words, the applicant’s argument during prosecution distinguishing its claims from the prior art based on different first and second formats overcomes the presumption based on claim differentiation that claim 1 encompasses first and second formats that are the same. See Fenner Invs., Ltd. v. Cellco P’Ship, 778 F.3d 1320, 1327 (Fed. Cir. 2015) (“Although claim differentiation is a useful analytic tool, it cannot . . . relieve any claim of limitations imposed by the prosecution history.”).

    “argument and evidence. As discussed above in the claim construction section, the recited first and second formats are limited to different formats. See supra Part IV.A. To satisfy this aspect of limitation 1D under its theory, Petitioner needs to show that in Danciu the format of the control information sent from the remote control to the server is different from the format of the control information sent from the server to the controlled device. The cited disclosures in Danciu, however, do not teach or suggest that these formats are different. Nor does Petitioner explain adequately how Danciu’s disclosures teach or suggest the two formats are different. We recognize that the control information in Danciu may be “processed” or “repackaged,” as Petitioner asserts, but it is not clear that the control information is processed or repackaged such that the format of the control information sent from the remote control to the server and the format of the control information sent from the server to the controlled device are different. Petitioner does not rely on Mahajan to teach or suggest the recited first and second formats but relies on Mahajan instead as providing “implementation details for transmission of commands for controlling a client.” Pet. 27. Petitioner contends that its proposed combination of Danciu and Mahajan would have provided a system where “Danciu’s remote control would translate commands associated with a first type of media playing application to a generic format, transmit them to the controlled device, which would translate them to a command associated with a second type of media playing application for execution.” Id. at 31. In other words, the controlled device would receive the generic commands sent from the remote control and then translate the generic commands. It is not clear how the proposed combination in this way teaches or suggests the format of a command sent from the remote control to a server is different from the format of a command sent from the server to the controlled device.” slip op. at 17

    “Aldrey and Mahajan meets limitation 1D under Petitioner’s second theory. Petitioner only alleges that it would have been obvious to an ordinarily skilled artisan that Mahajan’s RTS Media Abstraction Module could operate at a server like Aldrey’s service provider network 103. Pet. 65. The Federal Circuit has explained that “obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). Petitioner does not adequately explain why an ordinarily skilled artisan would have considered locating Mahajan’s abstraction module at a server, even if the abstraction module could operate at the server. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[T]here must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”). We note Petitioner further argues that combining Mahajan and Aldrey would have provided a system where “Aldrey’s end terminal would translate commands associated with a first type of media playing application to a command associated with a second type of media playing application on a STB.” Pet. 66–67; see also id. at 66 (“Mahajan’s server-command teachings could be implemented on Aldrey’s end terminal remote control.”). Arguing that Aldrey’s end terminal would translate commands seems inconsistent with Petitioner’s earlier argument for locating Mahajan’s abstraction module (which translates commands) at Aldrey’s network service provider. See id. at 65–67. Moreover, it is not readily apparent how command translation by Aldrey’s end terminal––rather than Aldrey’s network service provider–– teaches or suggests the format of a command sent from the end terminal to the network service provider is different from the format of a command sent from the network service provider to the STB. Petitioner does not close these logical gaps.” slip op. at 23

Yet, even if Petitioner were to argue that this limitation would have been obvious to an ordinarily skilled artisan in view of Zaid, we would disagree because Petitioner has failed to show how the unlocking step would have been obvious in view of a reservation.
