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

      “In Straight Path, the Federal Circuit held that the claim language “is connected to the computer network” has a facially clear meaning, that “the query transmitted to the server seeks to determine whether the second unit is connected at that time, i.e., connected at the time that the query is sent.” Straight Path, 806 F.3d at 1360.11 The Federal Circuit held that the query asks “whether the device ‘is’ connected, not whether it was connected or whether it is still registered as being connected even if that registration information is no longer accurate.” Id. The Federal Circuit further explained that “[i]t is not a reasonable interpretation of the claim language . . . to say that it is satisfied by a query that asks only for registration information, regardless of its current accuracy.” Id. The Federal Circuit explained, “[w]hen claim language has as plain a meaning on an issue as the language does here, leaving no genuine uncertainties on interpretive questions relevant to the case, it is particularly difficult to conclude that the specification reasonably supports a different meaning. The specification plays a more limited role than in the common situation where claim terms are uncertain in meaning in relevant respects.” Id. at 1361. Accordingly, the Federal Circuit construed the limitation “is connected to the computer network” as “is connected to the computer network at the time the query is transmitted to the server.” Id. at 1363.” slip op. at 11

      “and NetBIOS fail to determine whether a computer or process is connected to the computer network. PO Resp. 35, 49–51. In view of our construction of this claim limitation, we agree with Patent Owner. Microsoft Manual discloses that once a computer is registered with the WINS server (which is a NetBIOS Name Server (NBNS)) as active and on-line, the WINS server maintains a database of names and addresses as active and on-line by (1) releasing names once a computer is shut down properly and (2) requiring a renewal time period in which a computer must reregister. Ex. 1012, 62– 63, 68–69. Microsoft Manual discloses that in response to User Datagram Protocol (UDP) name queries, “a mapping in the database does not ensure that the related device is currently running.” Id. at 68. Microsoft Manual further explains that a “local WINS database should periodically be cleared of released entries and old entries that were registered at another WINS server but did not get removed from this WINS database for some reason.” Id. at 150. In other words, Microsoft Manual discloses that the WINS database may include entries of computers that are not currently connected to the WINS network. Accordingly, a query to as to whether a second process “is connected to the computer network” in Microsoft Manual will not determine whether the second process is connected to the WINS network at the time that the query is transmitted to the server. As discussed above in our claim construction analysis above (see Section I.E.1), a query as to whether a process “is connected to a computer network” or has an “on-line” status asks “whether the device ‘is’ connected, not whether it was connected or whether it is still registered as being connected even if that registration information is no longer accurate. It is not a reasonable interpretation of the claim language . . . to say that it is satisfied by a query that asks only for registration information, regardless of its current accuracy.” Straight Path, 806 F.3d at 1360. Microsoft Manual discloses that the WINS server has information that a process “was” connected to the computer network, and that information may no longer be accurate. See Ex. 1012, 68, 150. As such, we determine that Microsoft Manual does not disclose the claimed “is connected to the computer network,” “on-line status,” or “is accessible,” as construed herein. Similarly, NetBIOS discloses a registration process for resources or nodes to receive a unique name by registering a name. Ex. 1014, 379. During a name query (discovery), a datagram is sent requesting the name and address of another resource. Id. at 396. The NBNS maintains a database of resource names through explicit name deletion, where the node specifies a deletion function and implicit name deletion, which occurs when a node ceases operation. Id. at 379. NetBIOS explains that implicit name deletion “is a frequent occurrence.” Id. Implicit name deletion is managed by assigning nodes a specified lifetime for registered names, where a name is silently released if a node fails to refresh the registered name before the lifetime expires. Id. NetBIOS further discloses a mechanism where the NBNS may correct the information stored after an incorrect response is provided to a requesting node. See id. at 409. However, similar to Microsoft Manual, NetBIOS discloses that the information stored by the NBNS may be incorrect, and, therefore, will not determine whether a second process is connected to the computer network at the time that the query is transmitted to the server. Therefore, NetBIOS also does not disclose the claimed “is connected to the computer network,” “on-line status,” or “is accessible.” Given that the combination of Microsoft Manual and NetBIOS fails to teach or suggest the claims as construed, we need not reach the remaining arguments presented by Petitioner and Patent Owner.” slip op. at 19

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “Petitioner contends that “WINS is an implementation of NetBIOS” and, therefore, Petitioner contends that “one having skill in the art would have known about and been motivated to combine Microsoft Manual with NetBIOS.” Id. at 34 (citing 67 Ex. 1004 ¶¶ 88–89). We are persuaded by Petitioner that the combination is reasonable because Microsoft Manual demonstrates that Microsoft TCP/IP has combined the elements of NetBIOS and Microsoft Manual in the same manner in which Petitioner proposes to combine NetBIOS and Microsoft Manual. See 67 Ex. 1012, 3, 11. Microsoft Manual discloses that Microsoft TCP/IP for Windows NT provides support for application interfaces, including NetBIOS for establishing logical names and sessions on the network. Id. at 11. Microsoft Manual describes that “[w]hen WINS servers are in place on the network, NetBIOS over TCP/IP resolves names on a client computer by communication with the WINS server.” 67 Pet. 34 (quoting 67 Ex. 1012, 62). We are persuaded that Microsoft TCP/IP for Windows NT utilizes NetBIOS features for name resolution, as disclosed by Microsoft Manual, and a person with ordinary skill in the art would have readily combined the disclosures of Microsoft Manual and Microsoft Manual.” slip op. at 25

      “8. Conclusion We have reviewed the Petition and supporting evidence and find that Petitioner has shown by a preponderance of the evidence that claims 1, 2, and 5 of the ʼ469 patent are obvious over Microsoft Manual and NetBIOS, and claim 10 is unpatentable because it depends from a cancelled claim. Accordingly, we determine that Petitioner has demonstrated by a preponderance of the evidence that claims 1, 2, 5, and 10 of the ʼ469 patent are unpatentable.” slip op. at 29

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningDecided for petitioner

      “1. the cleavable linker and the protecting group are cleavable under identical conditions Proposed substitute claim 20 recites, inter alia, “a base that is linked to a detectable label via a cleavable linker,” a “protecting group attached via the 3' oxygen atom” of the nucleotide, and a step of “removing the label and the protecting group of the nucleotide . . . under a single set of chemical cleavage conditions.” Mot. 2 (emphasis added). These limitations are similar to those present in original claim 1, which we construed in our Decision on Institution. Specifically, we construed removal of the label and the protecting group under a single set of conditions “to mean what its plain language indicates: removal of the label and the protecting group under a single set of conditions.” Dec. 6. Neither of the parties contested this construction subsequent to institution, and we discern no reason to modify our initial construction for the purposes of this decision. Proposed claim 20 also requires that the cleavable linker comprise a disulfide linkage, but does not specify the protecting group. Thus, “a single set of chemical cleavage conditions,” under the broadest reasonable interpretation standard, limits the structure of the protecting group to one which can be cleaved under the same conditions as a disulfide linkage, but does not require a specific structure, such as a disulfide linkage.” slip op. at 8

      “Illumina was essentially 100%. This is a significant and unexpected improvement over the disulfide cleavages of Ruby (~86%) and Herman (87%).” Ex. 2004 ¶ 84. There is no testimony, however, that the stated results were due to the claimed nucleotide rather than the reducing agent. While Dr. Romesberg refers to the “disulfide cleavage yield” as being unexpected, he does not testify that this yield was attributable to the claimed nucleotide configuration, rather than the reducing agent which performs the disulfide bond cleavage. Illumina has not distinguished the Vermaas results from the prior art by showing that the nucleotide is responsible for the disulfide yield, rather than it being a property of the disulfide bond and the yield being “the mere recognition” of the bond’s “latent properties,” which “does not render nonobvious an otherwise known invention.” Baxter, 952 F.2d at 392; In re Geisler, 116 F.3d 1465, 1468 (Fed. Cir. 1997). Absent such evidence, Illumina has not shown that the claimed subject matter possesses “unexpected results relative to the prior art.” Galderma Labs., LP v. Tolmar, Inc., 737 F3d 731, 738 (Fed. Cir. 2013). “The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416.” slip op. at 28
