Motivation to Combine After summarizing its proposed combination, Petitioner provides a number of reasons for combining the references. Pet. 9–17. Petitioner breaks its motivation to combine arguments into three separate categories that we address below. See id. at 13–17. Patent Owner raises a number of arguments in support of its contention that “a POSITA would not have been motivated to combine the references to replace a measured value of one parameter with the measured value of another parameter,” which we address in the context of Petitioner’s arguments below. See PO Resp. 44–57. Many of Patent Owner’s arguments rely on Patent Owner’s proposed claim constructions for “replaced” and “measured value,” which we do not adopt for the reasons discussed above. For example, the first sentence in Patent Owner’s argument contends that “Naghavi, Hochstedler and Burnes do not disclose using the same screen area to display two currently measured parameters,” but we do not read the claims as requiring the display of “two currently measured parameters” consistent with Patent Owner’s construction for “measured values.” See id. at 44 (citing Ex. 2042 ¶ 125). Such arguments lack weight given that we have rejected their premise, and although Patent Owner’s arguments are suffused with references to its claim constructions, we attempt to identify where Patent Owner does not rely on those constructions in our analysis below.” slip op. at 47

Patent Owner therefore asserts a POSA would have understood the claimed “frequency modulated ECG acoustic signal” is a signal that is transmitted as a sound wave through the ambient environment, [and excludes] signals transmitted by electronic or wireless radio means, because claim 1 requires the acoustic signal to be “received from a built-in microphone of the smartphone.” PO Resp. 9; Ex. 2003 ¶ 26.

    “that Vyshedskiy’s disclosure of a list of preferred carrier frequencies represents a permissible “obvious to try” situation. In KSR, the Supreme Court stated that a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103. KSR, 550 U.S. at 421. And simply because the prior art “discloses a multitude of effective combinations does not render any particular formulation less obvious.” Merck & Co. v.

The instant facts represent a situation where, at the time of invention in 2010, it would have been obvious to try the known carrier frequencies of Vyshedskiy for modulation of the acoustic ECG signal of Albert in the claimed frequency range of 6 kHz to 20 kHz because these carrier frequencies would have been obvious alternatives to try to address Vyshedskiy’s disclosed design need for simultaneous measurement of heart sound auscultation and ECG heart cycle.

    “We decline to adopt Patent Owner’s construction because it improperly reads into claim 5 a requirement that the specification and claim language do not support. The specification passages relied on by Patent Owner do not expressly state that a vehicle independent state must be determined while the device is inside a vehicle, and contrary to Patent Owner’s argument, they also do not necessarily imply that. For example, the descriptions of “vehicle independent movement” and “vehicle independent event” in the specification (see Ex. 1001, 1:16, 42) refer to “phone falling to the ground.” “Falling to the ground” implies that the phone may be outside a vehicle, not inside. Further, the specification’s reference to detecting a vehicle dependent state “while also” recognizing a vehicle independent event does not necessarily imply that the vehicle dependent state and vehicle independent event are being detected simultaneously, as Patent Owner argues. In the language of claim 5, a “vehicle independent state” is recited in the determining step (step c), and the requirement that the portable device is located “inside a vehicle” relates to creation of an operation indicator, as part of the detecting step (step b). Patent Owner does not dispute this, and agrees that a portable device “not in the vehicle” can satisfy the determining step (step c). Tr. 73:5–8. Patent Owner, however, argues step c’s recitation that a “vehicle independent state” is based on step b’s “predetermined criteria” creates a link between “vehicle independent state” and step b, and thus an “express requirement” in step c that the device is located inside the vehicle. See Tr. 73:8–26, 76:1–3. We decline to read this requirement into the claim language. Although the claim language states that determining a “vehicle independent state” is based on “predetermined criteria,” and step b describes comparing “predetermined criteria” to an “operation indicator” that is created when the device is inside a vehicle, it does not limit the step of determining a vehicle independent state to a time when the portable device is inside a vehicle. Accordingly, we construe “vehicle independent state” to mean a state triggered when the portable device is moved independently of the movement of the vehicle.” slip op. at 23

    “We have again reviewed the record and the parties’ arguments, and again decline to import into the claim a requirement that the bio oil must be pre-treated. As we discussed in our institution decision, nothing in the ’185 patent indicates that the definition of bio oil is so limited. And we note that certain dependent claims of the ’185 patent, for example claim 21, specifically recite a pre-treatment step, leading to the conclusion that the bio oils of the independent claims are not limited to only pretreated bio oils. Neste’s new evidence introduced during trial is extrinsic to the patent, based on the testimony of Dr. Klein regarding the criticality of the iron content range. See PO Resp. 3 (citing Ex. 2029 ¶¶ 35–36, 38). In any event, we fail to see how the criticality of the claimed range mandates that the bio oil be pretreated prior to undergoing the claimed process. While Dr. Klein testifies that it is “clear from the ‘185 patent [that] a bio oil feed must be pretreated to render it suitable for commercial hydrotreatment” (Ex. 2029 ¶ 35), the portion of the patent he cites for this proposition states only that “bio-based feedstock (glyceride oil) to be used as feed material for hydrotreatment reaction can be purified to iron content of less than 1 to 0.2 w-ppm.” Ex. 1001, 4:50–55 (emphasis added). But this statement does not address the use of a bio oil that already contains an iron content within the claimed range, which therefore would not need purification. Indeed, the ’185 patent discusses “experiments with palm oil having very low level of impurities.” Ex. 1001, 4:45–46. Based on the foregoing, we maintain our view that the claim term requires no construction beyond its express language. The bio oil to be used in the method of claim 1 may be pretreated to achieve the claimed iron content, but pretreatment is not required by the claim.” slip op. at 11

    “The intrinsic record of the ’185 patent contains no indication that bio oil intermediate was a new term coined to signify a specific class of bio oils, as Neste contends. The written description contains a section devoted to providing specific definitions for terminology, including “bio oil,” “glyceride oil,” and “hydrotreatment.” Ex. 1001, 3:28–4:7. There is no mention of a bio oil intermediate, which would be expected if the inventors had intended to coin a new term. The only use of “intermediate” in the entire written description is as follows: “disclosed is a glyceride oil intermediate, which intermediate consists of glyceride oil from at least one renewable source and the iron content of said glyceride oil is less than 1 w-ppm.” Id. at 4:64–67. The sentence preceding that one states only that the “purification result can be obtained (depending on used feedstock) using pretreatment methods.” Id. at 4:61–62 (emphasis added). As can be seen, there is no mention in this passage that the “glyceride oil intermediate” must be pretreated, and no indication it is a novel term coined by the inventors. In any event, Neste has not given us reason to depart from the general presumption that a claim preamble is not limiting. The body of claim 6 recites a structurally complete invention, defining the bio oil intermediate according to its iron content. There is no reason to rely on the preamble of the claim for any structure, or for antecedent basis for any claim term. Therefore, we conclude that the preamble does not “breathe life and meaning” into the claim, but rather recites an intended use for the structurally complete invention recited in the body of the claim. As such, we decline to adopt Neste’s modified construction of the claim term, and maintain our prior construction of claim 6’s preamble.” slip op. at 14

    “Upon evaluation of the record as a whole, we believe Neste has the better argument, and conclude that the iron content of the bio oil in claim 1 should be determined when the feed is introduced to the catalyst bed. This interpretation is, most importantly, reflected in the structure of the claim. Claim 1 contains a single process step, of “subjecting a bio oil . . . to a hydrotreatment process.” Immediately following this process step is a wherein clause that requires the iron content of “said bio oil” to be within a certain range. The necessary implication of this claim structure is that “said bio oil” is referring to the substance that is being subjected to the hydrotreatment process, meaning the iron content that is relevant to the claim is the iron content at the time of hydrotreatment with a catalyst. The claim, as a comprising claim, does not exclude the presence of other treatment steps such as purification or dilution, but the structure of the claim does imply that these additional steps should be performed prior to determining whether the iron content of the feed is within the claimed range.” slip op. at 20

    “The claims at issue are apparatus claims rather than process claims. Accordingly, no specific means of achieving the interference fit is required. We construe “interference fit” as a structural limitation specifying the relationship of the bevel and frame. Even if construed as a product-by-process limitation (with the process being the insertion of a lens within a frame of lesser size), “determination of patentability is based on the product itself.” In re Thorpe, 777 F.2d 695, 697 (Fed. Cir. 1985). Patent Owner frames its proposed construction in terms of the process by which the fit comes about, but says little about the structural characteristics of the interference fit upon assembly. The Specification teaches that pressure upon the lens would lead to compression of the vertex. Ex. 1001, 4:40–55. That the vertex is in a compressed state is separately required in all claims by the “in compression” limitation. Id. at 8:54, 9:24. In view of the foregoing and in light of the parties’ arguments following institution, we modify our preliminary construction to recognize that an interference fit in this context implicates associated compressive forces. We, therefore, construe “interference fit” to mean “a relationship of the bevel of the lens and the receiving channel bottom of the eyeglass frame where such parts are in contact so as to exert frictional and compressive forces that secure the lens in place.”” slip op. at 17

    “Petitioner sets forth a rationale to combine the teachings of Gottschald and Schaeffer. Id. at 20. Petitioner argues that the teachings of Gottschald are applicable to the prescription lenses of Schaeffer as follows: POSITA would have been motivated by these teachings to use the method and device of Gottschald, with no change in its function, to edge the prescription plastic lens blank described by Schaeffer “so that the spectacle lens edge machining directly delivers a spectacle lens which is suitable for the selected spectacle frame, which has been ground to shape and which is provided with a bevel” (Gottschald, p. 6), and thereby to obtain the expected result of a “prescription plastic lens for use in an eyeglass frame” as recited in claim 1. Id. at 20. Patent Owner does not challenge the adequacy of Petitioner’s rationale with specificity. See PO Resp. 48–54. Rather, Patent Owner argues that Petitioner relies on “mere conclusory statements” throughout the Petition. Id. at 49. Such a generalized argument has little force. Having reviewed the evidence as a whole, we find that a person of ordinary skill in the art would have had reason to combine the teachings of Gottschald (regarding lens edging) and Schaeffer (regarding prescription lenses) in the manner Petitioner proposes.” slip op. at 28

    “structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” Catalina Mkt’g Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quoting Pitney Bowes, Inc. v. Hewlett–Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999)). For example, a preamble may be limiting when the disputed preamble phrase provides antecedent basis for a claim term in the body of a claim, the specification underscores that the additional structure recited in the preamble is important, or when the patentee clearly relied upon the preamble during prosecution to distinguish the claimed invention from the prior art. Id. at 808–09. “Conversely, a preamble is not limiting ‘where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention,’” id. at 808, or where the patentee uses the preamble to give “a descriptive name to the set of limitations in the body of the claim,” IMS Tech., Inc. v. Haas Automation, Inc., 206 F.3d 1422, 1434 (Fed. Cir. 2000) (“The phrase ‘control apparatus’ in the preamble merely gives a descriptive name to the set of limitations in the body of the claim that completely set forth the invention.”). The term “device” is not recited in the body of any claim of the ’019 patent,4 the body of claim 1 recites a structurally complete invention, and the preamble phrase “device for collecting and assaying a sample of biological fluid” specifies the intended use of the invention. Thus, we find the claims of the ’019 patent do not support construing “device” as a limitation. See Catalina Mkt’g, 289 F.3d at 808–09.” slip op. at 8

    “device” set forth above requires a single, unitary structure rather than a collection of separate structures that could be used during the test. See id. at 18 (concluding without analysis that the dictionary definition requires a “single, unitary structure”). Indeed, despite the ubiquitous use of the term “device” in patents generally, we are directed to no case in which the term “device,” by itself, was found to require a single, unitary structure. See Manual of Patent Examining Procedure, Section 2106, I (identifying “devices” as one of the four categories of statutory subject matter); Saffran v. Johnson & Johnson, 712 F.3d 549, 565 (Fed. Cir. 2013) (O’Malley concurring in part) (confirming that, in general, the term “device” is generic). Thus, we are not persuaded that the ordinary meaning of the term “device” requires a “single, unitary structure.” See Ex. 1023 ¶ 66 (Dr. Bohannon testifying that the word device, like the words “apparatus” or “system,” is merely a generic term that does not have a specialized meaning in the art and does not require a single, unitary structure). slip op. at 12

    “We do not find this argument persuasive. As noted above, we do not construe claim 1 to contain a method step of adding fluid to the container. We construe the first wherein clause of claim 1(c), instead, to require a structure that is capable of allowing liquid to enter the container when the flow control channel is properly disposed therein and is capable of directing this liquid to the sample loading zone of the assay test strip without the liquid having to migrate through an intermediate structure, such as a wicking material. We are persuaded—and Patent Owner does not dispute—that the apparatus of MacKay, as disclosed in Figures 8A–C, has a structure that is capable of achieving both functions. See, e.g., Tr. 26:10–30:20. First, given the open nature of the container, it is evident that liquid may be added to the container when the flow control channel is disposed within the container, and Patent Owner does not assert otherwise. See, e.g., id. Second, even if the fluid present in Figures 8A–C is considered, there is no intermediate structure in the container of MacKay that would prevent additional assay sample fluid from entering the container and being immediately directed to the sample loading zone of the assay test strips.6 Based on the foregoing, we find that MacKay discloses every limitation of claims 1 and 2 of the ’019 patent. Accordingly, Petitioner has demonstrated by a preponderance of the evidence that claim 2 is anticipated by MacKay.” slip op. at 21

    “To remove Dindi as a prior art reference, the record must establish either: (1) a conception and reduction to practice before the filing date of Dindi; or (2) a conception before the filing date of the Dindi patent combined with diligence and reduction to practice after that date. See Taurus IP, LLC v. DaimlerChrysler Corp., 726 F.3d 1306, 1323 (Fed. Cir. 2013).

REG Synthetic Fuels, 841 F.3d at 963. It is undisputed that Dindi was filed on June 13, 2008, and that Mr. Abhari filed on December 4, 2008 the application that issued as the ’804 patent. Dindi is not prior art—and, therefore, Neste’s ground of unpatentability fails—if either: (1) Mr. Abhari actually reduced to practice the invention of claims 2 and 5 between April 29 and June 13, 2008, or (2) Mr. Abhari exercised reasonably continuous diligence between June 13 and December 4, 2008, when the invention was constructively reduced to practice by filing of a patent application.
