“We find persuasive Dr. Wolfe’s supporting testimony that a POSITA would have understood the terms “PDK” and “RDC” to have “definite structure.” Ex. 1013 ¶¶ 35–56. In particular, we find persuasive Dr. Wolfe’s testimony that the term “PDK,” for example, “encompasses at least ‘a collection of circuit components that includes an antenna, a transceiver, and a controller and memory for storing information particular to a user.’” Id. ¶ 35. Dr. Wolfe’s testimony is consistent with the Specification of the ’188 patent. See Ex. 1001, 5:42–6:7, 3:48–62.

“We find that a rigid requirement as to the subject of a POSITA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record. See, e.g., Ex. 1067, 20:23–21:2 (Dr. Schaefer testifying that the fact the “name of [his] Ph.D. is immunology . . . does not change the fact that the core of [his] thesis training was really in molecular biology”), 22:3–15 (explaining that “the fact that the production of proteins recombinantly is mostly species agnostic”); Ex. 1069, 45:20–47:17 (Dr. Morris testifying that whether a person is a POSITA depends on the person’s “experience, [ ] publications,” and work done for the Ph.D. rather than the name of the Ph.D. program).

Accordingly, based on the entirety of the trial record, we find a POSITA with respect to the claims of the ’109 patent would have had a two years of experience with cloning genes, expressing cloned genes as proteins, and/or characterizing such cloned genes and proteins, with more education being able to substitute for experience, and vice versa. A POSITA may also have collaborated with others, including those with specific experience in utilizing or assessing horseshoe crab Factor C for endotoxin detection and quantitation.” slip op. at 9

“In this case, to show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23–24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). In our Institution Decision, we stated: Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)).

“Although the evidence before us shows that, in 2013, a POSITA knew how to recombinantly express genes in expression systems such as CHO or HEK-293 cell lines, the evidence shows that this was true only for genes whose genetic sequences were known or readily available.

“At the outset, we agree with Patent Owner that the Specification purports to define “major peaks” in the following sentence: “The ‘major peaks’ herein refer to peaks higher than the average of the peaks in the result.” Ex. 1001, 13:28–29. We determine that this language satisfies at least two of the criteria set forth in Alnylam. Specifically, the sentence at “refers to” to explain what qualifies as major peaks. That is not the end of the inquiry, however, as we find there is still some ambiguity as to whether the patentee intended to define “major peaks” so as to require so-called “minor peaks” in the claimed invention. See Bell Atlantic, 262 F.3d at 1268 (“[T]he intrinsic evidence must ‘clearly set forth’ or ‘clearly redefine’ a claim term so as to put one reasonably skilled in the art on notice that the patentee intended to so redefine the claim term.”). Importantly, the Specification does not treat the existence of minor peaks as prerequisites for the existence of major peaks. Indeed, the Specification does not discuss “minor peaks” at all. See generally Ex. 1001. Likewise, none of the claims of the ’227 patent, whether challenged or unchallenged, recites “minor peaks” or any additional peaks beyond the disputed “major peaks.” Id. at 23:30–24:42. Nor does the Specification include an example of FFT analysis results in which the average of the peaks therein is calculated and those higher than the average are identified as major peaks.8” slip op. at 9

“Petitioner has the better position. Huang2 teaches crosslinking and provides a reason for doing so (stability). In particular, Huang2 states: “To better mimic skin ECM, electrospun collagen fibers have been fabricated, however, the rapid degradation and poor mechanical properties determine that either crosslinking or combination with other materials is necessary to obtain a stable scaffold.” Ex. 1005, 1791 (emphasis added). It is true that, in describing work actually carried out, Huang2 states that blending with PCL was performed and does not mention crosslinking. See id. at 1792 (“Nanofibrous matrices of PCL and Collagen at a weight ratio of 3:1 were fabricated using electrospinning as previously described.”). However, the prior art – here, Huang2 – is not limited to that which it describes having created. See In re Mills, 470 F.2d 649, 651 (C.C.P.A. 1972) (“a reference is not limited to the disclosure of specific working examples”); see also In re Lemelson, 397 F.2d 1006, 1009 (CCPA 1968) (“The use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain.”); In re Fritch, 972 F.2d 1260, 1264 (Fed. Cir. 1992) (“It is well settled that a prior art reference is relevant for all that it teaches to those of ordinary skill in the art.”). Huang2 teaches two stabilization methods when using collagen in scaffolds. Huang2 states that one or the other “is necessary to obtain a stable scaffold” (when using collagen), but it does not preclude or teach away from using Patent Owner-cited testimony of Dr. Mikos is not as definitive as Patent Owner suggests; Dr. Mikos’s testimony is that a person of ordinary skill in the art “typically would not have done both.” Ex. 2015 ¶64 (emphasis added). The bottom line is that Huang2 teaches the person of ordinary skill in the art two ways to stabilize scaffolds/matrices comprised of collagen, provides a reason for doing so (stability), and does not teach away from using both. We are persuaded that a “scaffold comprising crosslinked fibers comprising collagen” would have been obvious in view of the cited teachings of Huang2.” slip op. at 33

“We are not persuaded by Appellant’s citations to either reference. As discussed above, Petitioner’s Ground 1 is premised on a person of ordinary skill in the art altering the native flat sheet structure of Huang2 by rolling it into a jelly-roll structure as taught by Kuo. See Pet. 41 (Beginning its claim 2 arguments with the following: “Claim 1 is obvious for the reasons expressed above in § X.A., supra, which are incorporated herein.”); see also Pet. Reply 17 (“[B]ased on the explicit teaching of Kuo, a POSA would have been motivated to take the electrospun flat scaffold made by the techniques of Huang2, seed it with the desired cells, and roll it to treat a tendon and ligament.” (emphasis added)). Indeed, the paragraphs of Kuo that Petitioner cites for disclosing “scaffold sheets,” explicitly describe rolling them into jelly-roll like structures. See Ex. 1018 ¶7 (stating that “the sheet is spirally contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct”), ¶22 (describing a method comprising “forming a tissue construct by contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct” and implanting it in a patient). Petitioner fails to argue that that “one or more elongated sheets” recited in claim 2 would encompass the rolled structure of its proposed modification. Nor does Petitioner articulate a claim construction argument that could support such an argument. Petitioner has failed to prove, by a preponderance of the evidence, that claim 2 would have been obvious over Huang2 and Kuo.” slip op. at 42

“device. The ’972 patent expressly defines endpoints broadly “as data sources or sinks.” Ex. 1001, 7:64–67. And the ’972 patent admits that Beel’s Figure 11 discloses the same endpoints depicted in the ’972 patent’s own Figure 4. Id. at 4:28–33, 16:44–67.

As additional support not separately emphasized by the parties in this connection, we note Dr. Almeroth’s technical explanation that, for data to pass from a functional device to a peripheral device, “both the functional device and the peripheral device must have ‘endpoints’”—a data source and a data sink—reasoning consistent with the ’972 patent’s definition.

“First, we agree with Patent Owner that, under the ordinary meaning of the claim language, the endpoint is an endpoint of the peripheral device, and that it must be “a data source or a data sink which is able to store or emit data, of the functional device exposed or made available on the first peripheral device.” Ex. 1001, 23:11–17. The limitation thus identifies a structure—an endpoint, residing on the peripheral device, that is a source or sink and that corresponds to (is “of”) the functional device—through which the communication recited in subsequent element (g) is carried out. By its terms, it imposes no requirement as to the direction in which data flows; it requires only that the endpoint be a data “source” or a data “sink” that is able to “store or emit” data. The operative transmit-and-receive communication “from the functional device to the processing device via the . . . endpoint” is recited in subsequent element (g), which we take up separately below. The disputed question under this limitation is therefore the structural one: whether Beel discloses, on the peripheral device, an endpoint that is “of the functional device.” Because the inquiry is structural and non-directional, we are not persuaded that the audio-out orientation of Beel’s described embodiment, on which Patent Owner relies, is dispositive of this limitation. device. The ’972 patent expressly defines endpoints broadly “as data sources or sinks.” Ex. 1001, 7:64–67. And the ’972 patent admits that Beel’s Figure 11 discloses the same endpoints depicted in the ’972 patent’s own Figure 4. Id. at 4:28–33, 16:44–67. Beel’s Figure 11 and accompanying description disclose a “[m]ass storage device 12,” a “USB audio device 14,” and a “USB HID device 13” on the peripheral device. Ex. 1005, Fig. 11, ¶¶ 320–323. Patent Owner’s own declarant conceded that a mass storage device is “a type of endpoint” (Ex. 1034, 43:19–21), and that “audio devices are endpoints” (id. at 57:5–61:4). We give reduced weight to Patent Owner’s contrary position to the extent it rests on the premise that a reference cannot disclose an endpoint unless it uses the word “endpoint” (Ex. 2030 ¶ 94; Ex. 1034, 43:19–44:16, 72:18–73:12); a premise that is inconsistent with the ’972 patent’s own broad definition and with the ’972 patent’s admission regarding Beel’s Figure 11. As additional support not separately emphasized by the parties in this connection, we note Dr. Almeroth’s technical explanation that, for data to pass from a functional device to a peripheral device, “both the functional device and the peripheral device must have ‘endpoints’”—a data source and a data sink—reasoning consistent with the ’972 patent’s definition. Ex. 1002 ¶ 125. Third, we find that the endpoint Beel discloses is a data source or a data sink that is “able to store or emit data, of the functional device.” We begin with the words of the limitation. The endpoint need only be “able to store or emit data”—language of capability, not a requirement that particular data actually traverse the endpoint in operation, and still less in a particular direction. And the endpoint is defined by the character of the data it handles: it is “a data source or a data sink,” which the ’972 patent instructs An audio endpoint, so understood, is characterized as an audio source or sink; its structure is not tied to any single instance of an audio device. On that understanding, Beel’s disclosure establishes the required capability directly. Beel discloses that “audio data is captured through a virtual sound card interface added as a logical device over the physical interface provided in the peripheral device,” Ex. 1005 ¶ 43, that the peripheral device “acts as a composite device comprising for instance a (virtual) audio speaker device,” id. ¶ 317, and that “audio data is captured at this interface . . . internally in the peripheral device 32” and streamed over the communications network, id. ¶ 319. Beel thus shows the endpoint on the peripheral device actually storing and emitting audio—and, correspondingly, video—data, which is the very type of data produced and consumed by the audio/visual functional devices connected to the base unit, including the microphones, cameras, speakers, and displays. Id. ¶ 120. An endpoint shown to store or emit audio and video data is necessarily one that is “able to store or emit” such data; the capability the limitation requires is thus established by Beel’s disclosure.” slip op. at 26

“1. Motivation to Combine Becerra and Couckuyt Petitioner argues that a person of ordinary skill in the art would have been motivated to combine the teachings of Becerra and Couckuyt because such a person would have recognized that Couckuyt discloses useful techniques of assigning data to Becerra’s charts, including assigning data to each axis. Pet. 34 (citing Ex. 1005 ¶¶ 19, 52, Fig. 5; Ex. 1003 ¶ 224). Petitioner contends that Couckuyt discloses associating data from a “spreadsheet document” with a chart, such as a “bar graph.” Id. at 35 (citing Ex. 1006, 6:1–37; Figs. 3a, 3c). below. Petitioner’s annotations to Figure 4 identify “Drop Zones” in red and “Data Fields” in Blue. Id. at 36. Petitioner contends Couckuyt discloses a “drag-and-drop user interface (DDUI) . . . associated with a data source, such as the two-dimensional data source 300,” and Figure 4 illustrates the DDUI permitting “value data fields and the characteristic data fields . . . to be dragged and dropped into drop zones.” Id. at 35–36 (citing Ex. 1006, 7:10–13). Petitioner contends that a “primary benefit of the charting DDUI is that the user can quickly change the data that is being presented in the chart,” and using Couckuyt’s techniques, a user can “quickly change the data” and see the desired effects. Id. at 36 (citing Ex. 1006, 1:18–19; Ex. 1003 ¶ 228). Petitioner contends that when Becerra’s control panel includes multiple charts, Couckuyt’s techniques would allow dragging-anddropping data from a data source to multiple charts, and would simplify the process of assigning data to multiple control panel components. Id. at 36–37 skill in the art would have also had a reasonable expectation of success combining Becerra with Couckuyt because the combination would amount to nothing more than incorporating Couckuyt’s well-known drag-and-drop techniques into Becerra’s system. Id. at 37 (citing Ex. 1003 ¶¶ 229–231). Patent Owner responds that Couckuyt focuses on selecting a data icon that corresponds to dragging and dropping data fields, not dragging and dropping data, while Becerra teaches that selecting various data ranges from the spreadsheet is desirable.

“Patent Owner’s arguments are unpersuasive. We are not persuaded that these differences between Kaplan, Ahmed, and Deforche are dispositive. To the contrary, we find the differences establish why a POSITA would have further modified Kaplan and Ahmed with the teachings of Deforche. Deforche expressly teaches that a disadvantage of wireless modems is that they require installation of an appropriate driver before applications running on the computer device can use the functionality of the wireless modem to connect to wireless networks. Ex. 1030 ¶¶ 2–3. Deforche solves this problem by using the processing device’s pre-installed drivers, which can be for a human interface device, to set up a modem/host communication interface for communication. Id. ¶¶ 4, 9. Because “[d]ata traffic from the computer device towards the wireless communication network and vice versa is routed over this modem/host communication interface and uses the generic communication protocol provided by the preinstalled generic driver,” Deforche states this “has the advantage that the need for a specific driver for the communication between the wireless modem device and the computer device can avoided” and “the advantage that a user can use the wireless modem device on a computer device on which he has no administrator rights, i.e. a computer specific driver for the wireless modem device.” Id. ¶ 9. “The motivation-to-combine analysis is a flexible one. Any need or problem known in the field of endeavor at the time of and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1379 (Fed. Cir. 2023) (internal quotations omitted). As the Federal Circuit held, “[t]here is a motivation to combine when a known technique has been used to improve one device, and a [skilled artisan] would recognize that it would improve similar devices in the same way.” Intel Corp., 61 F.4th at 1380. Here, Deforche establishes that utilizing an operating system’s preinstalled generic driver to provide a generic protocol communications between the processing device and a peripheral device was known for improving wireless modems because it does not require administrator rights and a specific driver to be installed to enable communications between the wireless modem device and the processing device.” slip op. at 20

“PO Resp. 30 (citing Ex. 2006 ¶ 58). Patent Owner’s proposal is too narrow in two respects. First, it mandates certain education and experience in RF neurotomy specifically. This is too narrow as the description of the scope of the invention set forth in the ’782 patent as described above is not limited to RF neurotomy. Second, it requires the POSA to be both a physician who performs thermal ablation (RF neurotomy specifically) and an engineer with training and experience “in the design and development of devices and methods” for performing the same. Id. This is too narrow because it excludes physicians and other advanced degree holders who research and design devices and methods for performing thermal ablation but do not actually operate on patients.
