    “Petitioner’s proposed construction of this limitation is supported by the specification of the ’582 patent. The ’582 patent discloses replacing a single sector coverage area with sub-sector coverage areas, at least one of which is an asymmetrical coverage area. Ex. 1001, 3:16–18. The ’582 patent discloses that the use of asymmetrical coverage areas permits the total coverage area to closely approximate the symmetrical sector coverage area being replaced, without creating excessively large sub-sector handover zones or introducing sever degradation in network performance. Id. at 3:18–24. The ’582 patent discloses creating the asymmetrical coverage areas by replacing an existing antenna with an antenna that has substantially the same coverage area, but divides the coverage area into a plurality of separate asymmetrical beams or sub-sectors. Id. at 4:32–38. As disclosed by the ’582 patent, the replacement antenna produces a plurality of separate beams, each defining a new sub-sector with only a small overlapping area between them and which together provide substantially identical coverage to the sector supported by the original antenna, to upgrade the single sector to a plurality of sub-sectors without significantly affecting neighboring sites. Id. at 4:51–57. The replacement antenna introduces asymmetry into the generated beam pattern. Id. at 4:58–60. The introduction of asymmetrical beams by the replacement antenna allows close approximation of the coverage area of the conventional sector antenna being replaced. Id. at 5:61–64. For purposes of this Decision, we adopt Petitioner’s proposed construction of “a plurality of sub-sector coverage areas extending therefrom, at least one of which is asymmetrical,” as a plurality of replacement sub-sector beams, at least one of which has an asymmetrical shape, where asymmetry includes deliberate or inherent asymmetry as the broadest reasonable construction consistent with the specification.” slip op. at 8

    “49 (Fed. Cir. 2005). There, the district court invalidated claims of the patent in suit on summary judgment based on the measured dimensions of a prior art patent figure. Id. at 1148. The Federal Circuit reversed, warning “that arguments based on drawings not explicitly made to scale in issued patents are unavailing.” Id. at 1149. Petitioner here does not identify any portion of Yea disclosing that Figures 4 and 8 are drawn accurately enough to determine an asymmetrical nature of the radiation patterns. Petitioner also fails to cite to any disclosure in Yea that identifies or describes an asymmetrical nature of the radiation patterns. Furthermore, Petitioner also has not explained why the shapes shown in the linear scale drawings of Figure 4 would show similar shapes when converted to a logarithmic scale. Additionally, Petitioner does not explain why the carrier to interference ratio shown in Figure 8 can be used to accurately measure antenna radiation beam patterns. We find Petitioner does not sufficiently establish that the plots shown in Figures 4 and 8 of Yea can be used to determine whether the antenna radiation beam pattern is asymmetrical. On the record before us, we determine the Petition and supporting evidence does not adequately establish a reasonable likelihood that Petitioner would prevail in showing that Yea anticipates independent claims 1, 13, and 20. b.

Under Rule 37 C.F.R. § 42.108, any genuine issues of material fact created by the testimonial evidence should be viewed in light most favorable to the petitioner solely for purposes of deciding whether to institute an inter partes review. Even reviewing the testimony of Mr. Collins in the light most favorable to Petitioner, we determine Petitioner has established only that asymmetrical beams may be used in a planar array antenna, but not that a person of ordinary skill in the art would have understood steered beams of a planar array antenna are necessarily asymmetrical. Mr. Collins cites to Litva (Ex. 1009) and Wästberg (Ex. 1018) in stating that prior art steered beams of a planar array antenna can be asymmetrical beams. Ex. 1024 ¶ 179. We credit Patent Owner’s arguments and the testimony of Mr. Cosgrove to determine Petitioner does not sufficiently establish the likelihood that a person of ordinary skill in the art would have understood that steered beams of a planar array antenna are necessarily asymmetrical. Further, Petitioner fails to set forth a sufficient rationale for why a person of ordinary skill in the art would use the asymmetrical beams of the prior art with the disclosure of Yea. Pet. 39–40.

    “(1) a related inter partes review (Pet. 8), and (2) a related matter before the U.S. District Court for the Central District of California (id. at 6–8). Regarding the related inter partes review, the Board previously construed the term “alert command” as raw alert data that is used to generate an alert signal, and the term “alert signal” as a signal that provides a visual or audio alert to a driver. Volkswagen Grp. of Am., Inc. v. Signal IP, Inc., Case IPR2015-00968, slip op. at 6–7 (PTAB Aug. 25, 2015), Paper 6. In order to reach our decision below, we need only construe the terms “alert command” and “alert signal.” We, therefore, decline to specifically construe any other claim terms at this time. We agree with Petitioner’s construction of the terms “alert command” and “alert signal,” consistent with our prior construction in IPR2015-00968. (See id. for our prior construction of the terms.) Thus, we construe the term “alert command” as raw alert data that is used to generate an alert signal, and the term “alert signal” as a signal that provides a visual or audio alert to a driver. Id. As explained below, even using Petitioner’s construction of these terms, Petitioner’s challenge fails to establish a reasonable likelihood that Petitioner would prevail in establishing unpatentability.” slip op. at 6

    “Petitioner asserts that it would have been obvious “to modify Pakett’s system such that it determines whether the ‘alert signal,’ as opposed to the ‘alert command,’ was active for a ‘threshold time’ as the claim requires.” Pet. 47. Petitioner asserts that this could be accomplished by activating a warning (alert signal) as soon as Pakett recognizes that an obstacle is present, and then applying the processing method previously applied to the persistence period instead to determine whether to sustain the warning. Id. at 47–48 (citing Ex. 1010 ¶¶ 101–04). Petitioner asserts that “one of ordinary skill in the art would consider Pakett’s delay of a warning until after the end of the persistence period to be nothing more than an optional redundancy,” and, thus, that this modification would have been obvious as “nothing more than a routine, obvious design choice.” Id. at 48 (citing Ex. 1010 ¶ 104). We disagree with Petitioner that the cited portions of Pakett’s teaching to delay the warning until after the persistence period is “nothing more than an optional redundancy,” at least because the cited portions of Packett do not indicate, either explicitly or implicitly, the 17 function of waiting for the persistence period before sending a warning to the driver indicators as optional or redundant. See id. Pakett clearly states that during the persistence period, “no warnings are sent to the driver indicators.” Ex. 1002, 6:50–51 (emphasis added). Pakett explains that waiting through the persistence period before sending warnings to the driver indicators prevents the system from incorrectly identifying stationary obstacles that were identified by the square wave generator 29 as valid obstacles in the blind spot. Id. at 7:56–63. Pakett thus explains that waiting through the persistence period before sending warnings to the driver indicators filters out false positives of objects in the blind spot of the vehicle.

    “The corresponding structure need not be explicitly identified but must disclose to a person of ordinary skill in the art what structure is identified in the specification. See Atmel Corp. v. Info. Storage Devices, Inc., 198 F.3d 1374, 1380 (Fed. Cir. 1999). It is unclear from the Specification whether the CPU, shown in Figure 2 as part of access control element 120, is the “higher-level processor” (Ex. 1001, 5:21–25), or some other processor running IOS (Ex. 1001, 1:33–37). It is also unclear which part of the access control element 120 is composed of “circuits adapted to particular process steps and data structures” (id. at 3:36–39). Here, the patent is at best unclear whether the claimed function is implemented in software executed on a general purpose CPU or in hardware as a collection of circuits. See Blackboard, Inc. v. Desire2Learn Inc., 574 F.3d 1371, 1385 (Fed. Cir. 2009) (“That ordinarily skilled artisans could carry out the recited function in a variety of ways is precisely why claims written in ‘means-plus-function’ form must disclose the particular structure that is used to perform the recited function.”). We also find that it is equally unclear whether the following means- plus-function limitations in claim 46, which appear to involve access control element 120, are implemented in hardware or in software structure (or some combination of both): “means for matching matchable information, said matchable information being responsive to said packet label, with said set of access control patterns in parallel”; “means for making a routing decision in response to said access result”; and “means for receiving a packet label responsible to a packet, said packet label being sufficient to perform access control processing for said packet.” Because the Specification of the challenged patent lacks sufficient disclosure of structure under 35 U.S.C. § 112, sixth paragraph, the scope of independent claim 46, and claims 47–52, 54, 56, and 59–62 that depend therefrom cannot be determined without speculation and, consequently, the differences between the claimed invention and the prior art cannot be ascertained.

    “Patent Owner argues, “Feldmeier’s packet forwarding is not the same as determining forwarding permissions (e.g., whether a packet is restricted from being transmitted from a selected source device to a selected destination device.)” Prelim. Resp. 31–32. Patent Owner further argues Feldmeier does not process a packet based on a forwarding permission. Id. We agree. Petitioner purports to show that “matching one or more characteristics of said packet with one or more access control specifiers,” recited in claim 63, results in “permission” to forward a packet. Petitioner states that “the information obtained from the CAM lookup governs the decision of whether to route or discard the packet.” Pet. 40 citing (Ex. 1003 ¶ 106). We note that Feldmeier discloses that “[a]ddress filtering is a process similar to address translation, except that rather than retrieving the data associated with an address, the process simply determines whether the address exists in a table of addresses.” Ex. 1005, 1:19–22. Feldmeier further discloses that “[t]he term address translation, as used herein, includes both address translation and address filtering operations.” Id. at 1:22–24. Also, as cited by Petitioner (Pet. 40), “Demultiplexer 1430 routes the packet . . . to either output packet queue 1450 or to discard line 1460 depending on the signal received from network address lookup 1440.” Ex. 1005, 13:24– 27. Finally, “[n]etwork address lookup 1440 is an apparatus for performing hierarchical address translations according to an embodiment of the invention.” Id. at 13:19–22. These passages suggest that a translation that yields no match (filtering) results in the packet being sent to the discard line. In contrast, the Specification supports that a successful match leading to a forwarding permission is contemplated by the claims. Ex. 1001, 7:1–12, 27–39 (determining an input or output permission by, among other things, “determining all of the successful matches”). Based on the above passages, Petitioner has not shown evidence that an affirmative match in Feldmeier results in a permission of packet forwarding, as required by claim 63. For the reasons stated above, we determine Petitioner has not shown sufficiently that Feldmeier discloses all of the limitations of independent claim 63.

    “We note that Feldmeier discloses that “[a]ddress filtering is a process similar to address translation, except that rather than retrieving the data associated with an address, the process simply determines whether the address exists in a table of addresses.” Ex. 1005, 1:19–22. Feldmeier further discloses that “[t]he term address translation, as used herein, includes both address translation and address filtering operations.” Id. at 1:22–24. Also, as cited by Petitioner, “Demultiplexer 1430 routes the packet . . . to either output packet queue 1450 or to discard line 1460 depending on the signal received from network address lookup 1440.” Id. at 13:24–27. Finally, “[n]etwork address lookup 1440 is an apparatus for performing hierarchical address translation[s] according to an embodiment of the invention.” Id. at 13:19–22. These passages suggest that a translation that yields no match (filtering) results in the packet being sent to the discard line. In contrast, the Specification supports that a successful match leading to a forwarding permission is contemplated by the claims. Ex. 1001, 7:1–12, 27–39 (determining an input [or output] permission by, among other things, “determining all of the successful matches”); see also Prelim.

    “In a computer network for transmitting information, messages can be restricted from being transmitted from selected source devices to selected destination devices. In known computer networks, this form of restriction is known as “access control” and is performed by routers, which route messages (in the form of individual packets of information) from source devices to destination devices. Ex. 1001, 1:4–10. Patent Owner also cites certain dictionary definitions. Id. at 10–11. Patent Owner states that “modifying” transmission is “nowhere in the record.” Id. Nonetheless, Patent Owner does not explain why the embodiment cited by the Petitioner above is not relevant to construing the claims. Because the embodiment cited by Petitioner suggests that access control may be used to change the destination address of a packet, we apply a broader definition than proposed by Patent Owner. We find the broadest reasonable construction of “access control” to include restrictions or modifications on the intended destination address to which a packet is to be transmitted.” slip op. at 8

    “As to the term “access control,” Petitioner asserts that “[a] person of skill in the art would have understood ‘access control’ to encompass restrictions or modifications of the transmission of a packet.” Pet. 5. Petitioner relies on the following passage from the Specification: [T]he invention can be used to augment or override routing decisions otherwise made by the router, using the access control element 120. In addition to specifying the packet 130 is to be dropped or forwarded to the higher-level processor, the access control element 120 can alter the output interface, which was selected by the routing element 110, to another selected output interface. The invention can thus be used to implement QOS (quality of service), and other administrative policies. Ex. 1001, 6:9–18. Patent Owner asserts “the plain and ordinary meaning of ‘access control’ is ‘restriction of packets from being transmitted from selected source devices to selected destination devices.’” Prelim.

    “‘discarding’ packets does not concern access control,” that Hendel’s “packets are only filtered or discarded as part of the packet forwarding process when there is a problem with the packet,” and thus, “Hendel refers to such filtering or discarding occurring when packets are ‘ill-formed’ or have ‘no appropriate destination[s]’ or ‘unsupported’ headers.” Prelim Resp. 21–22 (citing Ex. 1007, 8:39–40, 10:51–52, 13:9–11). We agree. Although we did not adopt Patent Owner’s proposed construction of the claim term “access result,” Patent Owner nevertheless makes a salient argument. We find Petitioner has not shown that the filtering decision is done “in response to [] at least one selected match” as required by claim 1. The Specification supports that a successful match leading to an access result is contemplated by the claims. Ex. 1001, 7:1–12, 27–39 (determining an input [or output] permission by, among other things, “determining all of the successful matches”); see also Prelim. Resp. 21 (“the ‘matching entry,’ at most, provides a destination for Hendel’s system to forward the packet . . . [but,] where a destination is found, the packet is forwarded; there is no disclosure to generate any access result to possibly restrict access to the destination.”).

    “Petitioner has not shown that Hendel’s filtering decision is determined based on “matching one or more characteristics of said packet with one or more access control specifiers.” Petitioner simply states that the packet is “filtered.” Petitioner’s Declarant relies on the following text from Hendel: “In a preferred embodiment, the merge logic 66 directs the input port 50i to take one of the following actions on a packet: filter the packet; forward the packet at layer 2; forward the packet at layer 2; forward the packet as a layer 3 flow; process the packet as a layer 3 route; and forward the packet as multicast router.”) Ex. 1003 ¶ 132 (citing Ex. 1007, 13:4–8.) This citation does not specify, however, that a characteristic of the packet was matched to anything in order to make the filtering decision, only that the decision was the result of “merge logic.” Petitioner’s Declarant also relies on the following text from Hendel: “After the forwarding logic 52 has determined what to do with the packet, it passes that information to the input port 50i. If the input port 50i does not filter the packet, then it [takes actions to forward the packet].” Ex. 1003 ¶ 132 (citing Ex. 1007, 9:21–25.) However, this statement does not even say that forwarding logic tells input port 50i to filter the packet, and certainly does not explain how forwarding logic 52 would make a filtering decision. Finally, Petitioner’s declarant relies on Hendel’s discussion of sending the packet to a firewall for further processing if no match occurs (Ex. 1003 ¶ 132 (citing Ex. 1007, 9:21–25)), but the claim does not recite what happens if there is not a match. The specification confirms that a successful match is contemplated by the claims. Ex. 1001, 7:1–12, 27–39 (determining an input [or output] permission by “determining all of the successful matches”). Neither Petitioner, nor Petitioner’s Declarant, has tied the matching in Hendel to a decision whether or not to forward a packet.

    “The corresponding structure need not be explicitly identified but must disclose to a person of ordinary skill in the art what structure is identified in the specification. See Atmel Corp. v. Info. Storage Devices, Inc., 198 F.3d 1374, 1380 (Fed. Cir. 1999). It is unclear from the Specification whether the CPU, shown in Figure 2 as part of access control element 120, is the “higher-level processor” which is described at Ex. 1001, 5:21–25, or some other processor running IOS described at Ex. 1001, 1:33–37. It is also unclear which part of the access control element 120 is composed of “circuits adapted to particular process steps and data structures” as described at 3:36–39. Here, the patent is at best unclear whether the claimed function is implemented in software executed on a general purpose CPU or in hardware as a collection of circuits. See Blackboard, Inc. v. Desire2Learn Inc., 574 F.3d 1371, 1385 (Fed. Cir. 2009) (“That ordinarily skilled artisans could carry out the recited function in a variety of ways is precisely why claims written in ‘means-plus-function’ form must disclose the particular structure that is used to perform the recited function.”). We also find that it is equally unclear whether the following means- plus-function limitations in claim 46, which appear to involve access control element 120, are implemented in hardware or in software structure (or some combination of both): means for matching matchable information, said matchable information being responsive to said packet label, with said set of access control patterns in parallel; means for making a routing decision in response to said access result; means for permitting or denying access for said packet; and means for receiving a packet label responsible to a packet, said packet label being sufficient to perform access control processing for said packet. Because the Specification of the challenged patent lacks sufficient disclosure of structure under 35 U.S.C. § 112, sixth paragraph, the scope of independent claim 46, and claims 47–52, 54, 56, and 59–62 that depend therefrom, cannot be determined without speculation and, consequently, the differences between the claimed invention and the prior art cannot be ascertained.
