    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “F.3d at 1279–80, we begin our analysis with the Specification of the ’711 Patent. The Specification indicates when a UAV (such as the recited “reference aerial vehicle”) navigates autonomously, it flies without manual control, and can, for example, track and fly to a target using information captured onboard the vehicle itself. See Ex. 1001, 3:24–28 (“[I]t may not be desirable to manually control the interceptor aerial vehicle to follow the target UAV. In some embodiments, the interceptor aerial vehicle is able to autonomously track and fly to the target UAV using machine vision based on images captured by a camera of the interceptor aerial vehicle.”). The Specification also indicates that “autonomous” means more than just “automatic flight,” and clarifies that autonomous navigation occurs when a UAV that previously received a target location from an external source subsequently turns and flies itself towards the received location. See, e.g., id. at 4:15–17 (disclosing that the detected location of a target may be provided to an interceptor “to allow it to automatically and autonomously fly toward the direction of the detected location”); 15:64–16:3 (automatic and autonomous navigation occurs when an interceptor’s navigation component and/or flight controller receive the location of a target, and adjust the interceptor “to turn and fly towards the received location . . . based on the received location”); 16:49–60 (“For example, a flight direction and/or speed of an interceptor aerial vehicle are automatically and autonomously adjusted based on a location and size of the target within the captured image. . . . This allows the flight path of the interceptor aerial vehicle to be dynamically adjusted to track and follow a moving target.”).” slip op. at 11

      “have had reason to combine Beard and Laufer in the manner proposed by Petitioner, the combination would not satisfy the Autonomous Navigation limitation required by claim 12 because Laufer’s autopilot commands are generated by and transmitted from a remote command center (i.e., Laufer’s central controller 115). PO Resp. 15–16. In its Reply, Petitioner does not dispute that Laufer’s autopilot commands are generated by Laufer’s central controller 115, which is remote from the aircraft being controlled. See Reply 13–17. Petitioner asserts, however, that the combination still satisfies the Autonomous Navigation limitation because these autopilot commands are generated without human input. See id. Based on the complete trial record, Patent Owner’s arguments are persuasive. See PO Resp. 15–16; PO Sur-reply 42, 1–6; Ex. 2025 ¶¶ 84–87. The flight of Beard’s UAV 100 under the control of Laufer’s autopilot commands does not satisfy the Autonomous Navigation limitation of claim 12, as we have construed that limitation, because Laufer’s autopilot commands are generated at a location that is remote from UAV 100 (Laufer’s central controller 115.) See, e.g., Ex. 1010 ¶ 40 (“Central controller 115 uses autopilot command module 440 to generate autopilot aircraft commands”), ¶¶ 26, 30 (clarifying that central controller 115 and the controlled interceptor aircraft are separate devices that may communicate through a “wireless connection”), Fig. 4 (depicting “aircraft control commands 475” being generated externally from the depicted “Interceptor Aircraft”); see also Ex. 2025 ¶¶ 95–95. Petitioner never disputes that, in the proposed combination, Laufer’s central controller 115 would remain external to Beard’s UAV 100. See Reply 13–17. Instead, Petitioner relies on its proposed construction of the Autonomous Navigation limitation, which would have encompassed such an arrangement. See id. Our construction of the Autonomous Navigation limitation, which did not adopt Petitioner’s claim construction position, is dispositive of Petitioner’s argument. We thus determine that Petitioner has not shown by a preponderance of the evidence that claim 12 would have been obvious over Beard and Laufer.” slip op. at 15

    • PTAB / AIA Trials › Motions to amend / substitute claimsMotion to amend granted in partGranted in part

      “the legal requirements set forth in 35 U.S.C. § 316(d) and 37 C.F.R. § 42.121. Lectrosonics, Paper 15 at 4, 7–8. For the reasons that follow, we determine that Patent Owner has satisfied this burden. 1. Proposal of a Reasonable Number of Substitute Claims A motion to amend must “propose a reasonable number of substitute claims.” 35 U.S.C. § 316(d)(1)(B); see also 37 C.F.R. § 42.121(a)(3) (“A motion to amend may cancel a challenged claim or propose a reasonable number of substitute claims.”). “There is a rebuttable presumption that a reasonable number of substitute claims per challenged claim is one (1) substitute claim.” Lectrosonics, IPR2018-01129, Paper 15 at 4; see also 37 C.F.R. § 42.121(a)(3). Patent Owner has shown it proposes a reasonable number of substitute claims by proposing a single substitute claim for each of challenged claims 1–4, 8–11, and 13–20. MTA 1–2, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 2. Amendments Respond to a Ground of Unpatentability “A motion to amend may be denied where … [t]he amendment does not respond to a ground of unpatentability involved in the trial.” 37 C.F.R. § 42.121(a)(2)(i). Patent Owner has responded to the grounds of unpatentability involved in this proceeding by amending the claims in response to the Petition’s asserted prior art. See MTA 2, 25, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 3. No Enlargement of the Scope of the Claims An amendment may not seek to enlarge the scope of the claims of the patent. 35 U.S.C. § 316(d)(3); 37 C.F.R. §§ 42.121(b)(1)–(b)(2). Patent Owner asserts that the amendments in the Motion do not enlarge the scope of the claims of the patent because each proposed substitute claim “retains all of the limitations of the corresponding challenged claim, and each proposed independent substitute claim adds further limitations.” See MTA 2, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 4. No Introduction of New Matter An amendment may not introduce new matter. 35 U.S.C. § 316(d)(3);” slip op. at 22

    • 112 supportDecided for patent owner

      “Having considered the evidence and argument cited by both parties, we determine there is sufficient written description support for the disputed portions of limitations [37.e1], [37.e3,] and [37.e4]. The ’452 application discloses selecting between groups of processing schemes (e.g., algorithms) depending on a confidence level, where the groups are, for example: high cost, high robustness algorithms; medium cost, medium robustness algorithms; and low cost, low robustness algorithms. See Ex. 2019 ¶¶ 146–147. These schemes or algorithms may be neural networks. See, e.g., id. ¶ 50 (including neural network as a type of algorithm); see also id. ¶¶ 109–110); see generally MTA Opp 1 (not disputing that schemes may be neural networks). Specifically, the ’452 application describes “algorithms that process video frames of one or more video data streams,” and “produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Id. ¶ 141. The ’452 application also discloses the concept of switching between neural networks based on confidence levels. In particular, the ’452 application discloses that a “process cycles through the processing schemes to produce a detection of an object,” for example, where “if the confidence number is higher than an activation number, an action is performed to stop or change a running group (i) and select or switch to group (ii).” Id. ¶ 146. More particularly, “a processing scheme from the group of (i) High cost (low refresh rate), high robustness algorithm[s] can select a cheaper processing scheme from the group of (ii) Medium cost, medium robustness algorithms.” Id. The ’452 application additionally discloses that schemes or algorithms (e.g., neural networks) are applied to individual video frames, and that the confidence levels that determine which neural network will be applied in the future are also derived from individual video frames. For example, as discussed above, the ’452 application describes that “[t]he processing schemes produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Ex. 2019 ¶ 141 (emphases added). The ’452 application also describes selecting and applying an individual neural network, rather than only selecting and applying a group of processing schemes. For example, as highlighted above, the ’452 application describes that “a processing scheme from the” “High” group “can select a cheaper processing scheme from the” “Medium” group. Id. ¶ 146 (emphases added). In our view, these disclosures, read together, would reasonably convey to one skilled in the art that the inventor had possession of the disputed subject matter described above. See Ariad, 598 F.3d at 1351.” slip op. at 24

      “Petitioner asserts that [t]he person of ordinary skill in the art (POSA) would have been an M.D. and/or Pharm. D who would have completed training in medical oncology, particularly in the field of gastrointestinal (GI) cancers, or a Ph.D. in clinical pharmacology, pharmaceutical sciences, pharmaceutics, and/or drug delivery, also particularly in the field of GI cancers, or their equivalents, along with at least 1-2 years of post-doctoral experience. Pet. 26 (citing Ex. 1002 ¶¶ 44–46). Patent Owner states that, for purposes of this proceeding, it does not dispute Petitioner’s proposed definition of a POSA. PO Resp. 8. Based on the entirety of the trial record, we adopt Petitioner’s proposed definition of a POSA’s skill level because it is consistent with the skill level reflected in the disclosures of the ’552 patent and prior art. 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).” slip op. at 9

      “We decline to discount Dr. Oberstein’s opinion based on the alleged conflict of interest and bias. Dr. Oberstein testified that the consulting fees he receives from Patent Owner reflect a small fraction of his income. Ex. 1210, 402:21–403:9. We also agree with Patent Owner that an oncologist prescribing an FDA-approved regimen does not evince bias. See Sur-reply 23; see also Ex. 1206, 49 (showing NALIRIFOX is a category 1, NCCN-preferred first-line therapy for metastatic pancreatic cancer), 69 (explaining category 1 is based upon high-level evidence). Petitioner also contends that Dr. Oberstein “offers conclusory opinions,” “fails to properly apply the law, continues to look at each reference in isolation, refuses to acknowledge logical suggestions in the art, and imports new limitations into the claims.” Reply 3–4. We evaluate each piece of evidence, including Dr. Oberstein’s opinion, as it relates to our substantive patentability analysis, and accord it proper weight.” slip op. at 9

      “In the DI, the Board stated that the ordinary understanding of a claim reciting a “method of treating metastatic adenocarcinoma of the pancreas” that comprises “administering an antineoplastic therapy to the patient” in order “to treat the metastatic adenocarcinoma of the pancreas” is that the “treatment” would have more than a de minimis therapeutic benefit or efficacy for the patient being treated. DI 14. We, however, rejected the notion that the claims “would require some particular degree of clinical efficacy” because “the level of clinical efficacy is not a claim limitation.” Id.” slip op. at 12

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Not reached

      “The parties, however, disagree over whether each recited dose must be the starting dose. Petitioner argues that “claim 1 requires that the method of treatment is a first-line therapy, but does not require that the claimed doses be used as a starting dose.” Paper 51, 1. In contrast, Patent Owner argues that “[t]he specification describes that the recited dose of each drug is a ‘starting’ or ‘initial’ dose.” Paper 50, 2 (citing Ex. 1001, 13:38–45, 30:5–7). For purposes of this Decision, we do not need to resolve this dispute. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (stating that claim terms need only be construed to the extent necessary to resolve the controversy). As explained below, we agree with Petitioner that, even if claim 1 recites the starting dose for each drug, Petitioner has shown, by a preponderance of the evidence, that the prior art teaches each dose and a POSA would have had a reason to start with the recited doses. See infra Section II.G.3; Paper 51, 3 n.2. Because we find that the prior art teaches or suggests the claimed subject matter even under Patent Owner’s proposed narrower claim interpretation, we need not further construe the disputed claim language.” slip op. at 16

      “Petitioner contends that a person of ordinary skill in the art “at, and before, the earliest claimed priority date of the ’158 patent . . . would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field and 2–3 years of experience in digital imaging systems,” adding that “[l]ess experience may be sufficient with additional education, and likewise, less education may be sufficient with additional work experience.” Pet. 6–7 (citing Ex. 1003 ¶¶ 16–18). Patent Owner does not offer a competing definition or dispute Petitioner's articulation. Based on the entire record, we adopt Petitioner’s characterization of the level of skill for one of ordinary skill in the art because that characterization, we find, is consistent with the ’158 patent and the asserted prior art.” slip op. at 9

      “We determine that the claims require a per-channel determination of integration time—that is, an integration time arrived at for each sensor or channel individually—and cannot be satisfied by a single global value merely applied uniformly across the sensors. We do not, however, read the independent claims to require that the per-channel integration times differ from one another.” slip op. at 11

    • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner

      “We adopt the definition clearly and unambiguously set forth in the specification, which was likewise adopted by the Court in the related litigation. See Pet. 7–8, 55; Pet. Reply 1–2 (district court construing the term to mean “the time the image sensor collects and integrates signal from the scene”). The specification states that the integrated photo-charge “is directly related to the time the image sensor collects and integrates signal from the scene,” and that “[t]his is known as integration time.” Ex. 1001, 4:4–7. Accordingly, the ’158 patent demonstrates that the inventors indisputably acted as a lexicographer for the term “integration time.”” slip op. at 13

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownOther

      “We construe “during a frame” to mean the period during which data for a single frame of an image is captured. The limitation is satisfied where the per-channel integration time is effectuated during the frame; it does not require that the integration time be re-determined mid-frame, nor does it require actuation of a “charge integration switch.” The specification’s only use of the phrase confirms this reading: “each camera channel is controlled during a frame under an independent integration time.” Ex. 1001, 3:45–50. Consistent with that usage, the specification describes selecting an integration time for each channel and then integrating the photo-signal “within a single frame of data,” and describes placing the charge-integration switch in a state to allow charge to accumulate for the selected period and then transferring the accumulated charge upon completion of the integration period. Id. at 4:51–54, 11:3–18. We decline Patent Owner’s proposal to require in-frame actuation of a charge-integration switch, for the same reason we decline to import that structure into “integration time.” We also decline to read the phrase to require mid-frame re-determination of the integration time, because the patent’s own embodiment selects an integration time and then integrates charge during the frame under that selected time. Ex. 1001, 4:51–54, 11:3– 18. So construed, “during a frame” is not redundant of the independentclaim limitation: it adds that the per-channel control occurs within a single frame (intrascene), as distinct from adjustment from one frame to the next (interscene).” slip op. at 15

      “We do not agree with Petitioner that the fact pattern before us is analogous to Rembrandt. The rationale to combine the teachings of Inoue and Smith provided in the Petition focuses on replacing incandescent bulbs with LEDs, and includes the generic statement that “[t]he numerous record-supported advantages, set forth in Smith provide a clear motivation for use of the teachings of Smith as applied to Inoue, so as to enjoy the advantages set forth in Smith.” Pet. 47. The testimony in Dr. Schubert’s Declaration at pages 99–100 cited in support of Petitioner’s Reply arguments was not cited or otherwise referenced in the Petition. See Pet. 46–55. We find that the Petitioner’s Reply is not responsive to the Institution Decision and is improper because it presents a new rationale to combine the teachings of Inoue and Smith that was not expressed in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Petitioner could have presented its rationale to make out a prima facie case of unpatentability in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Accordingly, we do not consider Petitioner’s new rationale to combine the teachings of Inoue and Smith presented for the first time in the Reply. Based on the entire record, but not including Petitioner’s new rationale and newly cited support to Smith and Dr. Schubert’s testimony (Exs. 1013, 1017) presented for the first time in the Reply, we are not persuaded that Petitioner sets forth in the Petition sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the circuit of Inoue to include a light source or LED light source with a twinkling or flashing effect in view of Smith’s teachings. See Pet. 46–47, 49–50, 51–53, 55.

      “We observe that, aside from Declaration testimony of Mr. Altamura and accompanying exhibits, Patent Owner does not offer any additional evidence to establish reduction to practice. An inventor’s testimonial assertion of inventive facts requires corroboration by independent evidence. Brown v. Barbacid, 276 F.3d 1327, 1335 (Fed. Cir. 2002). The purpose of the corroboration requirement is to prevent fraud, by providing independent confirmation of the inventor’s testimony. Kridl v. McCormick, 105 F.3d 1446, 1450 (Fed. Cir. 1997). Without the requirement of independent corroboration, there would be a great temptation to commit perjury and the adverse party would be effectively precluded from a successful rebuttal. Price v. Symsek, 988 F.2d 1187, 1194–95 (Fed. Cir. 1993). A rule of reason applies to determining whether the inventor’s testimony has been corroborated. See id. at 1195. “The rule of reason, however, does not dispense with the requirement for some evidence of independent corroboration.” Coleman v. Dines, 754 F.2d 353, 360 (Fed. Cir. 1985). Accordingly, based on the entire record, we find that Mr. Altamura’s Declaration testimony is uncorroborated. Yu is prior art to the ’252 Patent because Patent Owner is unable to establish actual reduction to practice earlier than the July 31, 2006, filing date of Yu.” slip op. at 51

      “Level of Ordinary Skill in the Art Citing testimony from Dr. Houh, Petitioner contends a person of ordinary skill in the art “would have had at least a B.S. degree in computer science or electrical engineering (or comparable degree) and two years of experience in networking or streaming media, or a M.S. in computer science or electrical engineering (or comparable degree).” Pet. 12 (citing Ex. 1003 ¶ 45). Patent Owner does not address the level of ordinary skill in the art in its post-institution papers. We adopt Petitioner’s definition of the level of ordinary skill in the art. On the present record, we are satisfied that this definition of the level of skill is consistent with the teachings of the ’234 patent and the asserted prior art.” slip op. at 11

      “On this record, we determine that the recitation “to achieve continuous presentation” is limiting and requires an amount of continuous (uninterrupted) playback/presentation after an upshift or downshift. The specification describes agent controller 702 determining whether to upshift based on a trigger threshold Θup, which itself is based on various factors including a current read ahead margin and a minimum safety margin. See Ex. 1001, 17:44–58. If agent controller 702 can sustain upshift quality, then it will upshift and request higher quality streams. See id. at 17:58–61. Conversely, when an upshift is not possible, agent controller 702 determines whether to downshift based a different threshold Θdown, which itself is based on the same sort of factors. See id. at 18:4–7. When the stream quality is not adequate, it downshifts. See id. at 18:7–14. These disclosures are similar to the language of claim 12, which recites “repeatedly generating a factor indicative of a current ability to receive the digital content at a rate sufficient for presenting the digital content as the digital content is received, . . . wherein the factor relates to a performance of the network” and “making the successive determinations whether to change the requested bit rate based on the factor to achieve continuous presentation of the digital content using the individually-requestable portions of the highest bit rate one of the copies determined receivable at that time.” Ex. 1001, 20:5–16 (emphasis added). That is, claim 12 refers to “achiev[ing] continuous presentation” based on what is “sufficient for presenting the digital content,” trading quality to ensure continuous playback.” slip op. at 14

      “server comprises at least two servers and wherein at least one streamlet is requested from a first of the at least one server and at least one other streamlet is requested from a second server of the at least one server other than the first server.” Ex. 1001, 19:7–12. Petitioner references its mapping of the “at least one server” in claim 1 to Leaning’s server 1. Pet. 20 (citing Ex. 1004, 2:15–16, 2:18–22, 2:31–32, 5:8–14, Fig. 1), 23 (citing Ex. 1004, 6:13–26, 9:3–7, 16:6–12), 37; see supra §§ II.D.2.b–c. Petitioner contends that, “[t]o the extent Leaning does not disclose at least two servers wherein one sub-file (streamlet) is requested from a first server and another sub-file (streamlet) is requested from a second server such an arrangement would have been obvious in view of the knowledge of a [an ordinarily skilled artisan].” Id. at 37. Citing the common nature of such an arrangement, Petitioner contends that an ordinarily skilled artisan would have been motivated to provide multiple web servers containing the same sets of sub-files for streams in order to have redundancy in the system and allow for clients to establish connections with multiple servers and request a first sub-file from a first web server and, if the connection between the first web server becomes congested or the first web server otherwise fails or becomes unavailable, request a subsequent sub-file from the second web server. Id. at 37–38 (citing Ex. 1003 ¶ 85; Ex. 1012, 108,5 Fig. 4-11). Patent Owner does not dispute Petitioner’s analysis for claim 3. We are persuaded that it would have been obvious to implement Leaning’s server 1 as two servers that store different streamlets based on Dr. Houh’s uncontested testimony about system redundancy. See Ex. 1003 ¶ 85. His testimony is backed by a contemporaneous reference about HTTP that shows requests for different objects from different servers over parallel TCP connections. See, e.g., Ex. 1012, 108–09, Fig. 4-11. Thus, we determine that Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 3 would have been obvious over Leaning.” slip op. at 34

      “As a general rule, unless the steps of a method claim actually recite an order, the steps are not ordinarily construed to require one.” Mformation Techs., Inc. v. Rsch. in Motion Ltd., 764 F.3d 1392, 1398 (Fed. Cir. 2014) (citation modified). “However, a claim requires an ordering of steps when the claim language, as a matter of logic or grammar, requires that the steps be performed in the order written, or the specification directly or implicitly requires an order of steps.” Id. (cleaned up). “[O]rdinarily in process claims steps taken concurrently are the equivalent of steps taken successively.” In re White, 39 F.2d 974, 975 (CCPA 1930); see also Cybersettle, 243 F. App’x. at 609 (finding “the step of calculating the differences between demands and offers can occur concurrently with the [next enumerated step of] receipt of multiple demands and offers” and “the testing step of ‘determining whether any of the differences fall within the predetermined settlement range’ may occur concurrently with the receipt and comparison of the bids” (citation modified)). This is especially true here, given that the recitations at issue are functional language in an apparatus (system) claim. We further agree with Petitioner that the ’328 patent discloses such concurrent performance of these steps: Either concurrent with or subsequent to the identification of road signs 30 and generation of asset management database 24, the computer processor 22 evaluates that portion 32 of each video frame or image that depicts a road sign 30 to determine a set of color values 40, 42 for each of a plurality of colors on the road sign 32. A retroreflectivity value is generated for each color portion 34, 36 on each frame of the tagged videostream 20 containing the road sign 30 that represents a different color value 40, 42. Ex. 1001, 5:52–60. Thus, the ’328 patent discloses concurrently detecting objects of interest (road signs) and determining whether the object of interest has a particular color value. slip op. at 13

      “Petitioner is correct to the extent that it need not show that “the features of [Schofield] may be bodily incorporated into the structure of [Gallagher],” but Petitioner must prove that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention.” Allied Erecting, 825 F.3d at 1381. For claim 9, Petitioner proposes to modify Gallagher’s system to use “Schofield’s determination of a light source’s location within a field of view” in Gallagher’s system. Pet. 23. Thus, Petitioner’s combination does not require the combination of Gallagher’s and Schofield’s sensors into a single system, and Patent Owner’s “sensor fusion” argument is inapposite. See Tr. 48:8–49:6 (Patent Owner’s counsel confirming that the problem of “sensor fusion” stems from combining disparate sensors in a single system). As noted above, Schofield teaches considering the relative location of the light source in determining whether the light source is from headlights or taillights (that is, an object of interest). See Ex. 1006, 9:26–35. We are persuaded that an ordinarily skilled artisan would be motivated to use this teaching in Gallagher’s device to help distinguish between road markers that are arranged side-by-side and have a reasonable expectation of success in doing so. See Ex. 1005 ¶ 40; Ex. 1003 ¶¶ 77 (“[An ordinarily skilled artisan] would have seen Schofield’s determination of a light source’s location within the field of view as advantageous because it would have allowed Gallagher’s computer to associate the measured reflectance level with the appropriate road marker.”), 79 (“[I]mplementing this determination would have required [an ordinarily skilled artisan] to implement only conventional techniques of image processing (identifying a location of a particular pixel within an array), which was well known by [an ordinarily skilled artisan], to predictably yield the result of the location within a field of view indicating an intensity value associated with a road marker. Given that Schofield and Gallagher disclose similar types of arrays, this combination would have merely required the use of Schofield’s known technique to improve Gallagher’s similar device in the same way.”).” slip op. at 30

      “Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan.

      “Thomason are in the same field of endeavor. Thomason describes a camera and method for correctly orientating pictures from the camera. See, e.g., Ex. 1004 ¶¶ 1, 2 29–40, Figs. 3a–3b. In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36).

The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason.
