“The respective proposed levels of qualifications for a person of ordinary skill in the art are similar, with Patent Owner proposing two years of experience compared to Petitioner proposing significant experience with remotely controlling fluid-handling devices, like SCADA systems. Patent Owner also proposes more extensive experience in lieu of educational experience. While we find Petitioner’s proposed qualifications to be acceptable, we adopt Patent Owner’s proposed qualifications for the purposes of this Decision because they offer a wider range of qualifications that nonetheless comport with the level of skill necessary to understand and implement the teachings of the ’871 patent and the asserted prior art. Our analysis and findings herein, however, do not turn on any differences in the qualifications adopted.” slip op. at 8

We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient. See Ex. 1005, 10:62–67, 14:35– 15:2, 15:62–16:32; see also Pet. 12–14, 16–18. Kahn discloses that “the communication unit 112B can include on-site alerts such as optical (indicator lights), audible alerts (e.g., alarm sounds), tactile (e.g., vibration of the unit) or can be interfaced to an appropriate control valve for simply shutting off the supply of fluid upon the detection of emergency events, for instance.” Ex. 1005, 10:62–67. Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively. Rather, the disclosure indicates that the communication unit 112B includes on-site alerts and that the local (non-remote) communication unit 112B can be interfaced with the control valve.” slip op. at 18

“Upon review of the prior art of record and the parties’ arguments, we adopt Patent Owner’s definition of the person of ordinary skill in the art for purposes of this Decision as it appears consistent with the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art). Petitioner’s proposed definition appears overly restrictive, as it requires a graduate degree in a narrow field of engineering or equivalent experience. We find that a bachelor’s degree with the accompanying experience proposed by Patent Owner more closely aligns with the prior art of record and the ’659 patent. We note, however, there is some overlap in the proposed levels of ordinary skill in the art because Patent Owner’s proposal includes “at least” a bachelor’s degree, which would encompass Petitioner’s master’s degree as well.

“We disagree with Patent Owner’s claim construction. By using the word “or,” the plain and ordinary meaning of “prone, kneeling, or standing” is that only one must be satisfied to meet the claim. See, e.g., SkinMedica, Inc. v. Histogen Inc., 727 F.3d 1187, 1199 (Fed. Cir. 2013) (“The disjunctive ‘or’ plainly designates that a series describes alternatives.”). Furthermore, and although claims are read in light of the specification, limitations in a specification are not read into a claim. In re van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993). Even if the Specification describes embodiments in which the user can begin in a prone position and then transition to a kneeling or standing position, as Patent Owner points out (see Prelim. Resp. 20), the claim does not recite the term “transitioning,” and we do not read the terms “each of” or “substantially flat surface” into this claim limitation. For example, the claim does not recite a “substantially flat” top surface and Patent Owner’s attempt to infer this structure into the claim is not supported under the law. See id. at 29–30.

“1. “wherein a user can be disposed on the top surface of the flotation device in a prone, kneeling, or standing position” With respect to the claim term “wherein a user can be disposed on the top surface of the flotation device in a prone, kneeling, or standing position,” Patent Owner points to passages of the Specification, arguing that all three positions are possible. Prelim. Resp. 19–21 (citing Ex. 1001, Abstr., 4:13–17, 4:33–40; Ex. 2006 ¶ 18). We do not agree with Patent’s Owner proposed construction because even if the Specification discloses that all three positions are possible, that is not what the plain language of the claim requires. Claim 1 recites “or,” which means that a user can be disposed on the top surface of the flotation device in any one of the three positions. See, e.g., SkinMedica, Inc. v. Histogen Inc., 727 F.3d 1187, 1199 (Fed. Cir. 2013) (“The disjunctive ‘or’ plainly designates that a series describes alternatives.”). Patent Owner does not identify any definition or disclaimer that would modify this plain meaning. See Thorner v. Sony Computer Entm’t Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012). Thus, we agree with Petitioner and apply the plain and ordinary meaning of the phrase “wherein a user can be disposed on the top surface of the flotation device in a prone, kneeling, or standing position,” to construe “prone, kneeling, or standing” as alternatives, and the prior art need only show one to satisfy this aspect of the claim.” slip op. at 13

“Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art). We nevertheless note that we would reach the same ultimate conclusion that claims 1, 3, 5, 9, 12, 13, and 15 (but not claims 20 and 21) have been shown to be unpatentable by a preponderance of the evidence were we to adopt Patent Owner’s proposal.

- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner
“We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass.

“On this record, we are sufficiently persuaded by Petitioner’s argument that a person of ordinary skill in the art would have combined the teachings of Perego and JESD79-2. As Petitioner correctly points out (Pet. 32), Perego discloses using DDR2 memory devices. Ex. 1071, 10:56–59 (“Other memory devices may be implemented on module 400, for example, Double Data Rate 2 (DDR2) DRAM devices and Synchronous DRAM (SDRAM) devices.”). On this record, we find this teaching to use DDR2 sufficiently supports Petitioner’s rationale to combine Perego with JESD79-2, which is the JEDEC DDR2 SDRAM Specification. Ex. 1064, 1 (cover page); see also Prelim. Resp. 44 (parenthetical noting that “JESD79-2 is a specification for individual DDR2 SDRAMs”). As to Patent Owner’s argument that Rambus memories lack a chip select network (Prelim. Resp. 25–26), the reference on which Patent Owner relies discloses that chip select information is still used in the particular Rambus devices described. See Ex. 1069, 11 (“[I]n the Rambus bus organization, all addresses, commands, data, and chip-select information are sent on the same bus lines.”), 12 (“[T]he example system uses a total of nine (9) lines to carry all necessary information, including addresses, commands, chip-select information, and data.”).

Claim 1 recites “at least one first memory integrated circuit in the first rank and at least one second memory integrated circuit in the second rank.” This language is met if there is one memory integrated circuit in each rank because “at least one” includes just one. On this record, we disagree with Patent Owner’s argument that this claim language “do[es] not define the term ‘rank’” but, rather, “provide[s] context that a claimed ‘buffer’ can be, but need not be, coupled to multiple memory devices in the rank.” See Prelim.

Resp. 44. We disagree. Petitioner presents detailed testimony from Dr. Wolfe explaining how Perego’s registered data transfers would have introduced delay. In particular, Dr. Wolfe, citing Perego’s disclosures of data latches and an internal clock to generate synchronizing clock signals (Ex. 1071, 12:65–13:5, 17:61–63, Fig. C), provides the following testimony: A Skilled Artisan would have understood from these disclosures that Perego’s latching of the data signals and the use of internal synchronizing clock signals adds a predetermined amount of time delay for each data transfer through the buffer because the output of the latch needs to be in synchronization with an internal clock. A Skilled Artisan would have understood that such registering of the data signals would require the addition of a fixed time delay, such as one clock cycle, for each registered data transfer through the circuitry with respect to the actual operational CAS latency of each of the plurality of memory integrated circuits. Ex. 1003 ¶ 360. Dr. Wolfe further explains how Perego’s “latching delays in the buffer device of Perego increase the overall CAS latency of the memory module compared to the CAS latency of the memory devices.” Ex. 1003 ¶ 362 (citing Ex. 1071, 12:65–13:5, 18:65–19:3, Figs. 5B, 5C). On this record, we find Petitioner’s evidence sufficiently persuasive to show that Perego teaches that “data transfers through the circuitry are registered for an amount of time delay such that the overall CAS latency of the memory module is greater than an actual operational CAS latency of each of the memory devices,” as recited in claim 1.

“we consider whether that construction was intended to encompass varying durations during the creating step or the displaying step. In its opinion, the Microsoft court observed that the defendants in that case argued that “before created,” and that “the ‘duration information’ is a parameter that the user can then interact with in order to vary the display of each resource.” Ex. 1014, 22. Patent Owner, the court continued, argued that “all that is required is for the user to maintain control over the actual presentation of the resource during the ‘displaying’ step, and that no duration information need be provided during the ‘creating a show structure of nodes’ step.” Id. at 22–23. The Microsoft court “agree[d] with [Patent Owner] that the user should be able to vary the duration of the content during show structure playback. This is the ‘interactive’ component of the claim.” Id. at 23; see also Prelim. Resp. 29 (arguing that this reasoning supports Patent Owner’s position that “the claim language expressly requires that the end user be able to ‘vary said duration’ for how long resource content currently ‘is being displayed’ to the user in ‘accordance with said show structure’ to which the resource belongs”). Here, the Microsoft court expressly states that the duration is varied during show structure playback, which is a clear reference to claim 1’s step of “displaying a content corresponding to each of said resources automatically in accordance with said show structure.” The Microsoft court “also finds that some duration information must be provided when the show structure of nodes is created,” that “‘parameter’ is a helpful concept for construction,” and that “the ‘duration information’ may be understood to be synonymous with a ‘parameter,’ as that timing information is the variable that will specify how long a particular content will be displayed.” Ex. 1014, 23. Thus, the Microsoft court construed claim 1 to require providing a variable duration parameter in the creating” slip op. at 13

“As noted above, the Microsoft court construed “interactively variable duration information” to mean “a parameter specifying how long a content is to be displayed by default before a subsequent content is displayed, where the viewer of the content can change the parameter.” Ex. 1014, 22. The construction itself suggests that the duration information is varied during display, because it is in the context of resources being displayed sequentially and “the viewer of the content can change the parameter.” As to Escobar, Petitioner contends that “[w]hen playing decision lists/timelines in the authoring tool using Button 174 (invoking subroutine E), the user is the viewer of the content.” Pet. 49 (citing Ex. 1004, 6:40–45). Thus, Petitioner appears to contend that, during the process of creating a show structure, the creator is a viewer if the creator can view the edited content corresponding to a node as the show structure is being created. Here, Petitioner would satisfy the “viewer” aspect of the Microsoft court’s construction by pointing to a creator viewing a piece of the show structure during the creating step, although Escobar does not teach that the creator can vary the duration of content while viewing it or that durations can be varied while a show structure (as opposed to a node being created) is being displayed in the displaying step, as discussed in more detail below.” slip op. at 13
