“We are persuaded by Patent Owner’s argument that claim 1 is not obvious over Avellan because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 21–23. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. PO Sur-reply 20. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

“Petitioner contends: A person of ordinary skill in the art (“POSA”) at the time of the alleged invention of the ’223 patent would have had a university degree in chemistry and additional expertise or a second university degree in the field of electrical engineering, particularly optoelectronics, or alternatively a university degree in electrical engineering and additional expertise or a second university degree in the field of chemistry. The person of ordinary skill in the art has spent several years studying the structure and function of organic optoelectronic components, in particular OLEDs, and has detailed knowledge of the chemical structure of light-emitting organic layers and the transport of charge carriers to these layers.

Under that standard, claim terms generally are given their plain and ordinary meaning as would have been understood by the ordinarily skilled artisan at the time of the invention and within the context of the entire patent disclosure. See Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). We construe claim terms only as relevant to the parties’ contentions and only to the extent necessary to resolve the issues in dispute. See Vivid Techs., Inc. v. Am.

“Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22. Petitioner also argues that an ordinarily skilled artisan would have recognized “that vaporizing materials together would best achieve Ma’s objective of assessing the current density using different Liq doping percentages.” Reply 22 (citing Ex. 1007, 811; Ex. 1020 ¶ 51). Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id. For the above reasons, we determine that Petitioner demonstrates by a preponderance of the evidence that Ma discloses joint vaporization as required by the challenged claims.” slip op. at 15

Claim 10 recites: determining, by the server, applicable settings for the selected vehicle, the applicable settings being settings that are preferred to be set as identified from the user profile and are compatible with settings that are settable in the selected vehicle. Ex. 1001, 33:10–14 (emphases added). The express claim language requires that the server determine applicable settings.

“However, contrary to Dr. Almeroth’s testimony and Petitioner’s position, Xiao’s server already does not attempt to command vehicles to do things they cannot do. Xiao teaches that server 118 generates commands for command codes that exist and are settable in the vehicle. Ex. 1010 ¶¶ 102– 103. As such, if there is no corresponding automobile setting, then Xiao’s server would not list those command codes for retrieval and would not send a command based on that retrieved command code to control the automobile systems to achieve the operator’s desired settings because that command code is not in the database. Our understanding of Xiao is further supported by Dr. Almeroth’s testimony: By listing them in the table of automobile command code information 606, Xiao shows that there are particular settings compatible with particular automobiles and particular desired settings. Thus, Xiao demonstrates the necessarily present characteristic that certain settings (e.g., commands) are compatible with certain automobiles. Ex. 1009 ¶ 96 (emphases added). We note that Dr. Malek further explains “the nonsensical result achieved by the combination would be that Xiao’s server, at best, in response to the command request issued by the operator, could ‘look up’ a command code to apply a vehicle-specific setting to that automobile 112, only to find that there is ‘none.’” We agree with Dr. Malek that there is a “None” command code in Xiao’s database when Xiao’s database already stores settings that are known to be settable in a specific vehicle per the operator’s preferences. Ex. 2011 ¶ 135. Thus, based on the complete record, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Xiao in combination with Hayashi render claim 10 obvious.” slip op. at 79

Dec. 44 (addressing substantially similar argument presented in preliminary response); see also Ex. 1001, 13:32–44 (claim 29). During trial, Patent Owner neither responds to this analysis nor points to a claim limitation that allegedly includes this requirement. Instead, Patent Owner points to the Specification, but this also fails to support Patent Owner’s contention. Although claims are read in view of the Specification (Phillips, 415 F.3d at 1315), they are not limited to the embodiments disclosed in it (id. at 1323). Patent Owner identifies (and we perceive) no passage in the Specification that could be read as redefining this claim phrase or disavowing part of its scope. See Thorner v. Sony Computer Ent. Am. LLC, 669 F.3d 1362, 1365, 1367 (Fed. Cir. 2012). In fact, the passages cited by Patent Owner are directed to the handling of a single flow, and none expressly indicates that an identical method must be used for each flow processed. See Ex. 1001, 6:25–31, 7:51–52, 8:12–17. Thus, we determine that the Specification does not justify importing the limitation proposed by Patent Owner into the claims. Accordingly, having reviewed the intrinsic record, we disagree with Patent Owner’s contention that claims 9 and 29 require computing a badness factor for each flow or all flows; rather, this claim limitation may be satisfied by computing a badness factor for a single flow.” slip op. at 11

“Having considered the parties’ arguments and evidence, we are persuaded that Copeland discloses this limitation. Copeland analyzes a flow’s statistics (including start time, end time, number of bytes, and number of packets) “to determine if the flow appears to be legitimate traffic or possible suspicious activity” and computes a concern index for the flow if it appears suspicious. E.g., Ex. 1007, 3:31–35, 7:38–67, 16:36–17:5. We find that Copeland’s concern index qualifies as a “badness factor for the flow . . . [that] provides an indication of whether the flow is exhibiting undesirable behavior,” as required by claim 9. E.g., Ex. 1007, 3:31–40, 4:30–33, Fig. 1 (identifying “‘bad’ flow(s)”). As Dr. Jeffay explains, an ordinary artisan would have understood that suspicious activity (such as a probe or network attack) is undesirable behavior. Ex. 1003 ¶¶ 211–212. We also find that Copeland teaches computing a concern index “based at least partially upon the set of behavioral statistics” because, for example, it uses the number of packets to compute the concern index. Ex. 1007, 7:64–67, Fig. 6 (setting concern index to number of packets); see also Ex. 1003 ¶ 213.” slip op. at 22

“Q. So Richardson contemplates a flow of control where the shunt calibration flag was not set, correct? A. That is reasonable. He shows an option -- an option of a “no” result from Step 406. Ex. 1047, 110:14–18. Dr. Wood also agrees that when the shunt calibration flag is not set and the procedure advances to Step 420, the contact relay in Richardson is still open: Q. Now, if the shunt calibration flag is not set and we go to Step 420, the starter contact relay in Richardson is still open, correct? A. That is my understanding. Id. at 77:10–13. Dr. Wood further agrees that when the shunt calibration flag is not set and the procedure advances to Step 214, where reverse polarity connection is tested, the starter contact relay is still open: Q. Okay. Then if we continue to Step 214 in this example, where the shunt calibration flag was not set, when we’re testing for the condition reverse jumper cable voltage, the starter contact relay is still open, right? A. That appears to be the case.” slip op. at 65

“Referring to FIG. 3, Klang states: “[t[he reverse polarity sensor 48, connected in a like manner across the battery terminals 20, 22, senses negative voltage indicating that the battery leads are connected backwards.” Ex. 1007, 6:20–23. Klang’s reverse polarity sensor provides an output signal (sensed negative voltage) indicating whether the battery has a proper polarity connection. Klang states: “[i]f the start button has not been pressed, at step 144, the OCV [battery open circuit voltage] is compared to a low negative voltage to determine whether the conducting cables 18 are properly connected to the battery 16. If the OCV is less than -0.5V, the method proceeds at step 146 to notify the operator that the leads are reversed.” Ex. 1007, 8:55– 60.” slip op. at 26
