“We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses element [1.2] because the evidence cited does not disclose a “first computer system being configured to provide remote control of the first pump or first valve” (i.e., a fluid-handling device). Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but Petitioner has not identified any disclosure of the capability to remotely control fluid-handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, Kahn’s disclosures that Petitioner relies on for allegedly teaching remote control are deficient. We discuss each.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“target value” is part of a command that is sent from a computing device to a server and then to a controller. The controller then receives a measurement of the fluid by a sensor and determines whether the measurement satisfies the “target value.” If the measurement does not satisfy the “target value,” further operations are undertaken. The recited operation sequence makes clear that the plain and ordinary meaning of “target value” is not as Dr. Wooley opines because the particular operating condition that a device is in at a particular time is represented by the measurement taken by the sensor, 11 Some claim language less relevant to construing “target value” was omitted for ease of reference. which the controller then uses to determine whether the measurement satisfies the “target value.” Additionally, claim 1 recites that the “target value” is sent as part of a command to the controller. The “target value” is not sent to the controller from the sensor, as might be expected if the plain and ordinary meaning of “target value” were as Dr. Wooley opines. Petitioner and Dr. Wooley’s construction would also result in “target value” meaning effectively the same thing as the measurement of the fluid by the sensor, a concept that is separately recited in claim 1 and to which the “target value” is compared. The Specification of the ’680 patent does not support Petitioner’s understanding of the plain and ordinary meaning of “target value.” Although the Specification does not recite “target value,” it recites “target state,” and describes “target state” sufficiently to understand the plain and ordinary meaning of “target” as used in “target value” and “target state.” In particular, the ’680 patent explains that “[i]n some embodiments, the process 104 includes receiving, via a network interface, from a remote user device, (e.g., via a command-center server) a command to change a state of a fluid-handling device to a target state.” Ex. 1001, 11:48–51. This portion reflects that the command is seeking to change a state of a fluid-handling device to a target state. In other words, the “target value” or “target state” is not generally “the particular operating condition that a device is in at a particular time”; rather, it is a value or state that the fluid-handling device is desired to be in, as Patent Owner and Dr. Durham explain. Additionally, just as claim 1 recites a directional component for the “target value” to be sent to the controller in a command, so too does the Specification describe a “target state” as being sent in a command from a remote user device. Thus, the Specification clearly supports the plain and ordinary meaning proposed by Patent Owner and Dr. Durham and not the plain and ordinary meaning proposed by Petitioner and Dr. Wooley. slip op. at 14

“time-stamped process data, report exception therein to the remote host, and extract and transmit time-stamped process data to the remote host.” Ex. 1005, Abst. (emphases added). Almadi explains that its remote field systems must include a plurality of controller units “to issue commands to, and gather and process data from a plurality of field devices, including remote systems and instruments, . . . [and] a database server for the storage of process data retrieved from the remote subsystems and instruments.” Id. at 2:22–30 (emphases added). Based on these disclosures, we agree with Patent Owner that Petitioner has not established that Almadi discloses element [1.4]. Specifically, the teachings from Almadi identified by Petitioner refer to process data, which is data retrieved from the remote subsystems/field devices. Thus, we understand that Almadi’s teaching—of using an Ethernet switch to transmit “process data”—describes transmitting data from the remote subsystems/field devices. See Ex. 1005, 3:13–17, cited in Pet. 15. But claim 1 and particularly element [1.4], recites “sending, with the server, the target value to the network address [which identifies a controller of the fluid-handling device13] via the network,” which is different than sending process data from the field devices to the remote host or database server for storage.” slip op. at 19

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.

“However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981.

“We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1. See, e.g., 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if — (3) the petition identifies, in writing and with particularity, . . . the evidence that supports the ground for the challenge to each claim . . . .”). First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89. But, as noted above, Jin does not disclose an element referred to as a “pilot parameter” and it is not clear what element Dr. Min intended to identify in Jin.8” slip op. at 18

“II. LEGAL STANDARD Pursuant to 37 C.F.R. § 42.71(d): A party dissatisfied with a decision may file a single request for rehearing without prior authorization from the Board. The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. When reconsidering a decision on institution, we review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion exists where a “decision [i]s based on an erroneous conclusion of law or clearly erroneous factual findings, or . . . a clear error of judgment.” PPG Indus. Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1567 (Fed. Cir. 1988).

“Owner’s argument persuasive because Perkins discloses embodiments with “mutations at I182 among a group of 20 other possible locations for modifications,” 13 of which are mutations of specific amino acids that “can be changed to any of the 19 other natural amino acids.” Id. Perkins discloses further that modifications at each of those 20 possible sites can be combined such that “one, two, or more” of the mutations can be made together in other embodiments (Ex. 1006, 17–18), or in other words, “each species [is] combinable to create a vast number of species.” Dec. 35. In addition to the locations of modifications expressly listed in Perkins, Perkins adds yet another option in which “the mutated VSV-G envelope protein is as described in Nikolic et al.” (Ex. 1006, 18), which “describes the crystal structures of VSV G bound to its native LDL-R receptor” that RCSB PDB depicts in entries 5OY9 and 5OYL (Dec. 18). We also considered Dr. Rose’s testimony about the crystal structures depicted in RCSB PDB, namely that a person of ordinary skill in the art would have been motivated to modify Perkins based on the VSV-G crystal structures in the RCSB PDB. Perkins taught that mutations to VSV-G “inhibit binding of VSV-G to the low-density lipoprotein receptor (‘LDL-R’), while preserving the VSV-G protein’s fusogenic function,” and expressly disclosed making a mutation at I182. (See, e.g., Ex. 1005 at 19:29-20:2, 20:29-21:14, 21:16-27; Ex. 1006 at 16.) The VSV-G crystal structures in the RCSB PDB taught that I182 is nearby negatively charged amino acids on the LDL-R. Thus, a person of ordinary skill in the art would have been motivated to incorporate a mutation which negated an interaction with the negatively charged residues in the LDL-R. (Ex. 1005 at 19:29–20:2; Ex. 1006 at 16.) Dec. 37. discussed above, “Perkins provides a list of many mutations and combination[s] thereof, but provides no direction as to which of the many possible choices is likely to be successful.” Id. at 37–38. Thus, we were not persuaded that choosing an embodiment with a mutation at I182 from Perkins’s other listed embodiments with 20 possible locations for modifications, combinations of modifications at 20 possible locations, and the mutations described in Nikolic and depicted in RCSB PDB is an “easily traversed, small or finite number of alternatives that KSR suggested might support an inference of obviousness.” Id. at 35. In view of these findings, we noted that we did not “find sufficient evidentiary support for a determination that the navigation of RCSB PDB crystal structures to achieve the missing limitation would have been ‘evidently and indisputably within the common knowledge of those skilled in the art.’” Id. at 38.” slip op. at 6

- Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportReference is prior artDecided for patent owner
“Having considered the parties’ positions and evidence of record, summarized above, we agree with Patent Owner that Perkins is prior art to the ’366 patent only to the extent that the subject matter disclosed in Perkins is likewise described in the Perkins Provisional. Accordingly, we do not consider Petitioner’s arguments that rely on subject matter unsupported by the Perkins Provisional. For example, support for Petitioner’s argument that Perkins discloses “mutant VSV-G envelope protein containing only four mutations at N180, I182, T352, and E353” is not found in the Perkins Provisional and is therefore not considered. Pet. 73 (quoted with Petitioner’s emphasis). Thus, insofar as Petitioner is suggesting that Perkins describes a list of mutations that is narrowed to four positions including a mutation at I182, rather than a listing of thirteen potential positions for mutations (and various combinations thereof with hypothetical mutations at a variety positions), we find no such narrower listing in the Perkins Provisional. Compare Ex. 1005, 22:2–5, with Ex. 1006, 17–18.” slip op. at 19

“genus even if the species are not themselves recited.” Bristol–Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1380 (Fed. Cir. 2001); see also, Atofina, 441 F.3d at 999 (“[A] very small genus can be a disclosure of each species within the genus.” (citing In re Petering, 301 F.2d at 682)). In Petering, for example, the prior art disclosed a small genus of only 20 compounds that included the claimed species. In re Petering, 301 F.2d at 682. In its discussion concluding that a small genus may anticipate a species of that genus, the Court of Customs and Patent Appeals explained that “it is not the mere number of compounds in this limited class which is significant here, but rather, the total circumstances involved, including such factors as the limited number of variations for R, only two alternatives for Y and Z, no alternatives for the other ring positions, and a large unchanging parent structural nucleus.” Id. at 681–682. Having considered the parties’ positions and evidence of record, summarized above, we do not find that Perkins discloses a limited class as exemplified in Petering. To begin, while it is undisputed that Perkins discloses a class of mutant VSV-G envelope proteins that encompasses the recited I182E or I182D mutations, it is also undisputed that Perkins does not disclose the I182E or I182D mutations. Prelim. Resp. 22. Furthermore, and by contrast to the limited class of compounds at issue in Petering, Perkins discloses a class of mutant VSV-G envelope proteins defined as proteins containing one or more of 20 possible mutations or alterations, a class that includes at least 254 proteins. Ex. 1006, 17–18; Prelim. Resp. 26–27. Furthermore, as Patent Owner correctly points out, “[t]he Perkins Provisional does not include any disclosure of the specific mutations to be made at any of these locations. That is, the Perkins Provisional does not indicate the other amino acid(s) to be substituted at the listed locations.” Prelim. Resp. 26. Thus, Perkins fails to provide a POSA with a “‘pattern of preferences’ that serves to narrow the genus.” See, e.g., Sanofi-Synthelabo v. Apotex, Inc., 470 F.3d 1368, 1377 (Fed. Cir. 2006) (“there is no such clear ‘pattern of preferences’ [as found in Petering] that serves to narrow the genus in claim 2 to a narrow class that includes clopidogrel bisulfate”).” slip op. at 22
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“Obviousness is a question of law based on underlying findings of fact.” In re Kubin, 561 F.3d 1351, 1355 (Fed. Cir. 2009). A conclusion of obviousness is appropriate where the prior art “contain[s] detailed enabling methodology for practicing the claimed invention, a suggestion to modify the prior art to practice the claimed invention, and evidence suggesting that it would be successful.” In re O’Farrell, 853 F.2d 894, 902 (Fed. Cir. 1988); see also, In re Kubin, 561 F.3d at 1359 (KSR “actually resurrects [the Federal Circuit]’s own wisdom in In re O’Farrell”). However, to render a claim obvious, prior art cannot be “vague” and must collectively, although not explicitly, guide an artisan of ordinary skill towards a particular solution. Bayer Schering Pharma AG v. Barr Labs., Inc., 575 F.3d 1341, 1347 (Fed. Cir. 2009). That is, when a field is “unreduced by direction of the prior art,” and when prior art gives “no indication of which parameters were critical or no direction as to which of many possible choices is likely to be successful,” an invention is not obvious. Bayer Schering, 575 F.3d at 1347 (citing In re O’Farrell, 853 F.2d at 903). Having considered the parties’ positions and evidence of record, summarized above, we are not persuaded that Perkins discloses a finite set or limited class of 19 mutations. Pet. 66. Rather, we agree with Patent Owner that Perkins discloses a large genus of mutant VSV-G polypeptides containing at least 254 species—“Perkins Provisional discloses mutations at I182 among a group of 20 other possible locations for modifications[,] . . . [13] of these 20 positions are specific amino acids that . . . can be changed to any of the 19 other natural amino acids” —each species combinable to create a vast number of species. Prelim. Resp. 32. Perkins does not indicate any preference among the 13 disclosed mutations, does not indicate any preference among the 19 other amino acids, and does not indicate any preference as to which mutations should be combined to successful effect. Ex. 1006, 17–18. Thus, while Perkins discloses that one or more mutations “inhibit the envelope protein’s ability to bind its native target, while preserving the envelope protein’s fusogenic properties,” beyond that, a POSA would have no direction for selecting the route to create the I182E or I182D mutations specified by the challenged claims among the various unpredictable alternatives suggested by Perkins. Ex. 1006 at 16; Ex. 1002 ¶ 193. We do not find this to be the easily traversed, small or finite number of alternatives that KSR suggested might support an inference of obviousness.
