At the oral hearing, Petitioner stated it had no dispute with Patent Owner’s proposal. Tr. 16:21–17:2. We determine that an express definition of the level of ordinary skill is not required. The level of ordinary skill in the art can be reflected in the cited prior art references. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Here, the specification expressly defines atomic blocks: Defining Atomic ("A") blocks (sometimes called units) – “A” blocks are the netlist blocks that will be physically partitioned to create place and route units (PRUs). "A" blocks may contain only standard cells or they may contain additional levels of hierarchy. For the purpose of partitioning the circuit design into PRUs, the "A" blocks are indivisible. Ex. 1001, 4:8–12.

    “The difference in the opinions of the two experts is that Dr. Sechen believes a person of ordinary skill in the art would have an additional four years of experience, education, or a combination of the two, beyond that proposed by Dr. Alpert. See Ex. 1009 ¶ 7. According to Dr. Alpert, the difference in the proposed levels of ordinary skill in the art is not material to any dispute over claim construction or patentability in this inter partes review. Id. We accord greater weight to Dr. Alpert’s opinion as to the level of ordinary skill in the art because he has experience in both teaching students and working with engineers in the industry, while Dr. Sechen’s experience is primarily in teaching. Compare Ex. 1007 ¶¶ 7, 21 with Ex. 2012 ¶¶ 3, 5. Moreover, based on our review of the ’434 patent and the types of problems and solutions described in the ’434 patent and cited prior art, we agree with Dr. Alpert’s opinion on the level of ordinary skill. Accordingly, we find that a person of ordinary skill in the art at the time of the ’434 patent would have a Bachelor’s degree in electrical engineering, computer engineering, or in a related field and at least one year of work experience relating to memory systems, and would be familiar with the design of memory devices, memory modules, and BIST.” slip op. at 10

    “The above disclosure uses the term “operable independently” to describe the data handlers as being discrete and functioning without being physically or logically connected to each other. Based on our review of the ’434 patent, the specification and claim 27 both use the term “operable independently” in the same manner, i.e., to describe a feature of the data handler that is distinct from its data generation feature. We agree with Petitioner, therefore, that when interpreted in the context of the ’434 patent in its entirety, the claim term “operable independently” “merely means that each data handler can operate without influence or control by any of the other data handlers.” Reply 5. The ’434 patent specification uses the term “operable independently” in accordance with its plain and ordinary meaning, and we find no basis for applying the narrower construction advanced by Patent Owner to any of the challenged claims. Accordingly, we interpret “operable independently” as “operable without influence or control by another.” See Cuozzo, 793 F.3d at 1278–79.” slip op. at 19

    “Based on the above description in Averbuj, we agree with Patent Owner that Averbuj describes memory interfaces (the alleged data handlers) that are configured to produce address and control signals, and that Averbuj describes producing address and control signals in certain circumstances, e.g., when Averbuj’s sequencer (the alleged control module) specifies writing data in a particular pattern that requires transformation to conform to a particular configuration of a memory module. See PO Resp. 33. We also agree with Petitioner, however, that Averbuj’s memory interfaces are further configured to apply to the memory modules the same address and control signals received from, and produced by, the sequencers for testing (see Reply 15), e.g., when the sequencer sends signals that can be applied, without modification or transformation (see Ex. 1003 ¶ 56), directly to a memory module irrespective of its physical configuration. Thus, Petitioner has shown, by a preponderance of the evidence, that Averbuj’s sequencer meets the limitation of “a control module configured to generate address and control signals for testing the memory devices” as recited in challenged independent claims 1, 20, and 29 of the ’434 patent.” slip op. at 41

We agree with Patent Owner that the Reply does more than merely respond to or rebut arguments made in Patent Owner’s Response; rather, it sets forth a theory that was not presented clearly in the Petition. Patent Owner’s position is supported by the fact that Dr. Sechen, whose skill level is at least (and appears to exceed) that of the ordinary artisan, apparently was unable to envision how Huang and Averbuj could be combined. Further, Dr. Alpert’s second declaration includes, at a minimum, opinions as to the understanding of the ordinary artisan with respect to the teachings of Huang and Averbuj that were not presented in his first declaration. In our judgment, consideration by the Board of the above-noted arguments in the Reply and evidence presented in Dr. Alpert’s second declaration in support thereof would be improper under 37 CFR § 42.23 and unfair to Patent Owner. We have, however, reviewed and considered the arguments in the Petition and evidence therein, and are in agreement with Patent Owner that Petitioner has not provided adequate explanation or evidence to support its contention that one of ordinary skill in the art would have had a reasonable expectation of success in combining Huang and Averbuj.

To overcome this presumption, the patentee must “clearly set forth” and “clearly redefine” a claim term away from its ordinary meaning. Id. The disavowal must be “unmistakable” and “unambiguous.” Dealertrack, Inc. v. Huber, 674 F.3d 1315, 1322 (Fed. Cir. 2012). This standard is “exacting.” Thorner v. Sony Computer Entm’t Am.

We do not find that Patent Owner has met this exacting standard, and, in the absence of an express definition for the term “thin-film filter,” we decline to incorporate Patent Owner’s lengthy recitation as the broadest reasonable interpretation of the term “thin-film filter.” In view of the plain and ordinary meaning of the term “thin-film filter” and the disclosure in the ’953 patent Specification, we construe the term “thin-film filter” to mean “a filter comprised of stacked layers for filtering light.”” slip op. at 13

    “Claim 30 further requires “a mask in intimate contact with at least one of said filter surfaces, said mask substantially opaque in at least some spectral region.” For this claim limitation, Petitioner relies upon Nicholson’s disclosure of absorbance layer 12, shown in the annotated Figure 1 above. Pet. 31 (citing Ex. 1005, 3:23–25). Nicholson states that the “absorbance layer 12 [is] formed of highly optical absorbent material such as carbon black.” Ex. 1005, 3:24–25. Petitioner argues that this highly absorbent material, such as carbon black, would be substantially opaque in at least some spectral region. Pet. 31–32 (citing Ex. 1003 ¶ 94). As discussed above, we construe a mask as “a material that blocks the passage of at least selected photons.” We are persuaded that Petitioner sufficiently demonstrates that absorbance layer 12 in Nicholson provides a material that blocks the passage of at least selected photons. In its Response, Patent Owner argues that Nicholson does not anticipate because it fails to teach a thin-film filter with layers having packing factors approaching 100%. PO Resp. 6–7. As we do not adopt Patent Owner’s proposed construction of “thin-film filter” requiring these limitations, Patent Owner’s arguments are moot. In fact, during the oral argument, Patent Owner conceded that, if the Board were to adopt the same construction for “thin-film filter” as set forth in the decision to institute, Nicholson would anticipate claim 30.

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.

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.

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.

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.

In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). Petitioner proposes constructions for the terms “access control,” “associative memory,” “packet label,” “responsive,” and “megapacket.” Pet. 5–9. We determine that the terms “associative memory,” “packet label,” “responsive,” and “megapacket” do not require express construction for purposes of our Decision.” slip op. at 6

    “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. Resp. 10. Patent Owner relies on the following passage from the Specification (id.): 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.” slip op. at 7

    “‘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.”). Neither Petitioner, nor Petitioner’s Declarant, has tied an actual match in Hendel to a decision whether to forward the packet or make some modification to the intended transmission of the packet.” slip op. at 11

    “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.

Pet. Reply 8–10. The hydrocarbon tackifying resins of Table 1 are listed on pages 4 and 5 of the Eastotac Brochure. Ex. 1002, 4–5. At the top of page 4 just above Table 1, under the heading “Applications,” the Eastotac Brochure states “[t]hese resins are especially suited for low-molecular-weight polyethylene-based hot melt adhesives where elevated temperature resistance and high cohesive strength are required.” Ex. 1002, 4 (emphasis added); Pet.

The next page following Table 1 (page 6) discloses exemplary hot melt adhesive compositions in Table 3, each one of which includes an “Eastotac resin” and thermoplastic base polymer in specified composition ranges by weight that overlap with the composition ranges recited in claim 22 of the ’404 patent. Although Patent Owner counts ten different applications for the Eastotac resins of Table 1, the Eastotac Brochure provides specified composition ranges for use of the Eastotac resins in only one application – hot melt adhesives. Ex. 1002. As recently reiterated by the Federal Circuit, “a reference can anticipate a claim even if it ‘d[oes] not expressly spell out’ all the limitations arranged or combined as in the claim, if a person of skill in the art, reading the reference, would ‘at once envisage’ the claimed arrangement or combination.” Kennametal, Inc. v.

PO Resp. 24–26 (citing Ex. 1039, 104:17–20, 106:2–11, 115:2–5). Dr. Hsu testified that, although Table 1 does not list a specific application for the Eastotac resins and Table 3 lists “Eastotac resin” rather than a specific Eastotac resin from Table 1, a fair reading of the Eastotac Brochure indicates “all the ones [resins] in Table 1 can be used in this [Table 3] composition,” including H-142R.

Dr. Hsu further testified that one of ordinary skill would have been “motivated” to use the H-142R resin, listed in Table 1, in the hot melt adhesive compositions of Table 3 when a high peel value and high heat resistance were desired, “because Eastotac® H-142 has the highest Tg of the Eastotac® resins in the Eastotac Brochure.” Ex. 1015 ¶ 54. We find Dr. Hsu’s unrebutted testimony to be persuasive. As in the Kennametal case, we find that one of ordinary skill in the art of polymer science and engineering immediately would have envisaged the use of the H-142R hydrocarbon tackifying resin in combination with either APP or EVA thermoplastic base polymer in the exemplary hot melt adhesive compositions in Table 3 of the Eastotac Brochure.

    “Patent Owner does not provide any evidence that contradicts Dr. Hsu’s testimony. PO Resp. 40–41. We also are not persuaded by Patent Owner’s argument challenging the sufficiency of Petitioner’s evidence in support of a motivation to combine the asserted references. Rule 41 of the Uniform Freight Classification Committee provides good reason for one of skill in the art to make the asserted modification to the compositions disclosed in the Eastotac Brochure or Exxon Reference. The compositions contain hydrocarbon tackifying resins, and the Eastotac Brochure expressly states that the resins listed therein are “especially suited” for hot melt adhesives where “elevated temperature resistance and high cohesive strength are required.” Ex. 1002, 4. The ’404 patent, moreover, acknowledges the known use of higher Tg tackifying resins to increase heat resistance, and the rail freight packaging requirement for maintaining a hot melt adhesive bond up to 74º C. provides a known application and commercial rationale for using a high peel value adhesive, as recited in claim 27. We also find Dr. Hsu’s opinion articulates a specific, persuasive reason, based on the evidence of record, to explain why a person of ordinary skill in the art would have used a high Tg tackifying resin to achieve a hot melt peel value > 70 ºC., with a reasonable expectation of success. For the reasons stated above, we determine that one of ordinary skill in the art would have been motivated by the teachings of Litz to modify the adhesive compositions disclosed in either the Eastotac Brochure or the Exxon Reference to obtain a composition having a peel value of greater than about 70º C., with a reasonable expectation of success. Therefore, we conclude Petitioner has satisfied its burden of proving by a preponderance of the evidence that either the Eastotac Brochure or the Exxon Reference in combination with Litz would have rendered claim 27 of the ’404 patent obvious to a person of ordinary skill in the art under 35 U.S.C. § 103.” slip op. at 24

    “1. Means-plus-function Claiming Independent claim 1 of the ’107 patent includes a series of means-plus- function limitations. 35 U.S.C. § 112 ¶ 6.5 A means-plus-function limitation “shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.” Id. The claim limitations in the ’107 patent are drafted using the accepted “means for” construct followed by a specified function, without further recitation of structure to achieve the recited function. Triton Tech of Texas, LLC v. Nintendo of Am., Inc., 753 F.3d 1375, 1378 (Fed. Cir. 2014); see Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1347 (Fed.

We construe the following claim limitations for purposes of this decision, in accordance with the principles stated above. 2. “display means coupled to said processor for facilitating the entry of such data by a user” The ’107 patent specification links a touch display screen, computer screen, or other electronic screen with the claimed function of “facilitating the entry of 5 Section 4(c) of the Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), re-designated 35 U.S.C. § 112, ¶ 6, as 35 U.S.C. § 112(f). Because the ’107 patent has a filing date before September 16, 2012, the effective date of section 4(c) of the AIA, we refer to the pre-AIA version of § 112, ¶ 6. such data by a user.” Ex. 1001, 2:62–67 (“In the case of a touch display screen, the screen may function both as a display means and an input means. In the case of a keyboard or mouse, the operation thereof would normally be carried out in conjunction with display means 108, and/or a computer screen or other electronic screen.”); Pet. 11. During a game, the electronic screen display prompts the device user (game scorer) to enter sports game event data related to the progress of the game. Id. at 3:7–12. The data being entered, “such data” in the claim language under consideration, has antecedent basis in the “input means . . . for inputting data related to events of said sports game in real time.” Accordingly, we conclude that the broadest reasonable interpretation of the limitation “display means coupled to said processor for facilitating the entry of such data by a user,” consistent with the ’107 patent specification, is “a touch screen, computer screen, or other electronic screen coupled to the processor for facilitating the entry of data related to events of a sports game by a user in real time, and equivalents thereof.”” slip op. at 6

    “2. “display means coupled to said processor for facilitating the entry of such data by a user” The ’107 patent specification links a touch display screen, computer screen, or other electronic screen with the claimed function of “facilitating the entry of 5 Section 4(c) of the Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), re-designated 35 U.S.C. § 112, ¶ 6, as 35 U.S.C. § 112(f). Because the ’107 patent has a filing date before September 16, 2012, the effective date of section 4(c) of the AIA, we refer to the pre-AIA version of § 112, ¶ 6. such data by a user.” Ex. 1001, 2:62–67 (“In the case of a touch display screen, the screen may function both as a display means and an input means. In the case of a keyboard or mouse, the operation thereof would normally be carried out in conjunction with display means 108, and/or a computer screen or other electronic screen.”); Pet. 11. During a game, the electronic screen display prompts the device user (game scorer) to enter sports game event data related to the progress of the game. Id. at 3:7–12. The data being entered, “such data” in the claim language under consideration, has antecedent basis in the “input means . . . for inputting data related to events of said sports game in real time.” Accordingly, we conclude that the broadest reasonable interpretation of the limitation “display means coupled to said processor for facilitating the entry of such data by a user,” consistent with the ’107 patent specification, is “a touch screen, computer screen, or other electronic screen coupled to the processor for facilitating the entry of data related to events of a sports game by a user in real time, and equivalents thereof.”” slip op. at 6

    “c. Claim 1 – “customized by the user to reflect desired data” We are further persuaded that Hameen-Anttila discloses hierarchical menu- based screen displays that may be “customized by the user to reflect desired data,” in accordance with our claim construction. We agree with Petitioner, that the setup menu in Hameen-Anttila (Fig. 4a) allows a user to select desired display menus (e.g., for golf) that will cause other menus not to be displayed (e.g., for hockey, bowling, and baseball) during a user’s input of golf-specific data in real time. Pet. Reply 7–8 (citing Ex. 1002, 5:21–24; Ex. 1014 (Dahbura Dec.) ¶¶ 20–21). As Dr. Dahbura notes, Patent Owner’s expert, Dr. Locke, agrees that choosing not to display a menu screen is a form of user customization. Ex. 1014 ¶ 21 (citing Ex. 1017, 72:19–73:3). We further agree with Petitioner that Patent Owner’s proffered distinction between Hameen-Anttila’s “mere usage” of hierarchical menu-based screen displays and “customizing” such displays is illusory and not consistent with the description of user customization in the ’107 patent. Pet. Reply 8 (citing Ex. 1014 ¶ 22). The individual drop-down arrows in Figure 4b further suggest the ability of a user to change the menu-based screen displays to permit the user to input desired data for the illustrated golf game. Therefore, we determine Hameen- Anttila discloses an action by the user to configure the hierarchical menu-based screen displays to permit desired data to be gathered for one or more sports games. d. Claim 1 – “transferring statistical information based on such inputted data” Patent Owner’s argument asserting Hameen-Anttila does not disclose the transfer of “statistical information based on such inputted data” also is off the mark. As noted above, Hameen-Anttila discloses that sports game event data is input into an electronic scorekeeping device and transmitted via a communications network to a server while the sports game is ongoing. Ex. 1002, 2:40-51, 2:57– 3:13. We are not persuaded by Patent Owner’s argument that the transfer of statistical information “based on” inputted data requires some form of calculation that necessarily excludes inputted data as part of the transferred “statistical information.” PO Resp. 17–19. Patent Owner does not offer a claim construction or request construction of quoted claim phrase at issue, even though Patent Owner’s argument presumes a specific definition of the phrase without explaining why it is consistent with the broadest reasonable interpretation standard. Pet. Reply 2. The language in claim 1 of the ’107 patent recites “a processor,” but it does not recite a calculation function performed by the processor on inputted data. Pet. Reply 11. The claim language also does not exclude inputted data from “statistical information” or limit “statistical information based on such inputted data” only to statistics calculated from the inputted data. Id. The preamble of claim 1, recites “gathering, processing and distributing statistical information.” Ex. 1001, 8:11–12 (emphasis added); see also PO Resp. 19 (citing Ex. 1001, 1:56–60 (“The present invention advantageously provides an electronic scorekeeping device for gathering, calculating and distributing statistical information.”)). Gathering statistical information, when read in light of the ’107 patent specification, refers to inputting sports game event data into the scorekeeping device for transmission to a central database as part of the statistical information transfer. Pet. Reply 11 (citing Ex. 1001, Abstract (“This [inputted] data is transferred in real-time in a system according to the invention via a communications means to a central database.”); Ex. 1014 ¶¶ 25–28). The ’107 patent does not define “statistical information” or “statistical information based on such inputted data.” The ’107 patent also does not exclude inputted data from the description of statistical information. Pet. Reply 12 (citing Ex. 1014 ¶ 27). To the contrary, and consistent with the understanding in the art, the ’107 patent uses the words “data,” “statistics,” “statistical data,” and “statistical information” interchangeably and with significant areas of overlap. Id.; see also id. at 4 (citing Ex. 2002 ¶ 30 (“The terms ‘statistics,’ ‘data,’ and ‘statistical information,’ are widely used in computer systems, but they are often used in very general ways with broad meanings in which their meanings have significant areas of overlap.”)). We further credit Dr. Dahbura’s testimony, that a person of ordinary skill in” slip op. at 18
