    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableNot shown unpatentable

      “We agree with Patent Owner that Petitioner’s contentions in this ground do not cure the issues for limitations 1D and 1E. Petitioner’s contentions in this ground involve combining Khan and Ali’s teachings of identifying a horizon line and lane lines with Choe. For example, Petitioner argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have combined known elements according to known methods to yield predictable results” and that “[i]mplementing these known mathematical models in Choe’s calibration system, according to their known functions, would have yielded predictable results.” Pet. 39. Petitioner further argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have used a known technique (predictive models) to improve similar devices in the same way” and that “[u]sing predictive models for Choe’s lane and horizon prediction would have also applied a known technique (predictive models) to a known device (a manual annotator device) ready for improvement.” Pet. 40. Petitioner’s proposed combination, therefore, still relies on Choe’s teachings of transmitting an overlaid image to an annotator device. We note that Petitioner asserts that, “[o]nce Khan in view of Ali identifies the horizon and lane lines, it overlays the horizon line and/or lane lines on the video, as shown in the screenshots below.” Pet. 41–42. Although Petitioner mentions Khan and Ali’s teachings with respect to video here, Petitioner does not adequately explain how the teaching of an overlaid video would be combined with Choe’s single image annotator teachings. As discussed above, Choe discloses transmitting a single overlaid image to the annotator” slip op. at 23

      “Thus, Petitioner has not provided sufficient evidence and argument to explain how the additional teachings of Khan and Ali teach limitations 1D and 1E in combination with Choe. Petitioner, therefore, has not demonstrated unpatentability of claims 1–5 by a preponderance of the evidence. F. Obviousness over Choe and Workman (Claims 1–4) Petitioner asserts that claims 1–4 would have been obvious over the combined teachings of Choe and Workman. Pet. 47–52; Pet. Reply 26–30. Petitioner asserts that, “if [Patent Owner] alleges that Choe does not explicitly disclose which predictive models it uses or whether it uses predictive models to identify the horizon line, a [person of ordinary skill in the art] would have searched for references that use predictive models and how such models were used,” which “would have led to Workman, which discloses predictive models to identify the horizon line.” Pet. 47. According to Petitioner, “[u]sing Workman’s predictive model to identify the horizon line would also have merely been combining known elements ([convolutional neural networks (CNNs)] and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way.” Pet. 48–49. Thus, Petitioner relies on Workman to teach a predictive model to identify a horizon line. See Pet. 47–49. Choe with respect to limitations 1D and 1E. Indeed, Workman involves horizon line estimation in single images. See Ex. 1011, 10 (§ 5) (“We introduced Horizon Lines in the Wild (HLW), a new dataset for single image horizon line estimation, to address the limitations of existing horizon line detection datasets.”). Petitioner, therefore, has not demonstrated unpatentability of claims 1–4 by a preponderance of the evidence.” slip op. at 24

      “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. Accordingly, we determine that Petitioner has not demonstrated by a preponderance of the evidence that the subject matter of independent claim 9 and dependent claims 3, 5, and 6 would have been obvious over the teachings of Inoue and Smith.” slip op. at 32

      “Based on Petitioner’s citations to Holler, Inoue, and Dr. Schubert’s testimony (Ex. 1013), we are persuaded Petitioner sets forth 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 “use the resistive value as taught by Holler in the circuit of Inoue to control the illumination of the light sources so that the other illumination devices in the serial light string will not go dark or change illumination if one of the LEDs fails or becomes disconnected.” Pet. 27; see KSR, 550 U.S. at 418. Based on the entire record and including the reasons explained above in Section II.D.2. addressing anticipation of claim 1 by Inoue, we determine Petitioner shows by a preponderance of the evidence that the subject matter of claims 1 and 10 would have been obvious over Inoue and Holler.

      “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

      “We do not agree with Patent Owner’s argument because it advocates for the importation of functional limitations from the ’794 Patent Specification into the claims––namely the disclosure that the bypass circuit continues to conduct electricity, and keeps the remaining lights lit, even when one or more individual lighting elements in the series are burned out, missing, or defective. See PO Resp. 7–9. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). An extraneous limitation is “a limitation read into a claim from the specification wholly apart from any need to interpret what the patentee meant by particular words or phrases in the claim.” E.I. du Pont de Nemours, 849 F.2d at 1433. Moreover, the language that Patent Owner wishes to import into the claim from the Specification is functional language that describes the function of the resistor bypass circuit. As explained below in the section addressing the subsequent claim recitation “conducting current at all times across the light sources when current is flowing through the circuit regardless of whether the LED light source are conducting current therethrough,” functional language is evaluated in view of the applied prior art to determine whether it imparts additional structure to distinguish the claimed invention over the prior art. Accordingly, to the extent the preamble recitation is limiting, we need not provide an express construction for “[a] resistor bypass circuit for a series lighting circuit.”” slip op. at 7

Patent Owner does not dispute Petitioner’s proposed definition of a person of ordinary skill in the art for the purpose of institution. See PO Resp. 2.

      “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).

      “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.

      “limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20.

      “We agree with Patent Owner that the phrase “in response to” in claim 1 requires a causal relationship wherein the patient must be tested for MSI-H and, if he or she is determined to be MSI-H or dMMR, then the patient is treated with 10 mg/kg of pembrolizumab every 14 days. In claim 1, a biological sample from the patient must be tested to determine if the cancer is MSI-H and, if so, the patient is treated with a therapeutically effective amount of pembrolizumab. For this reason, if the prior art teaches the limitations of 1) testing a biological sample obtained from a patient having cancer to determine that the patient’s cancer is microsatellite instability high or mismatch repair deficient, and 2) treating the patient with a therapeutically effective amount of pembrolizumab if the patient’s cancer is determined to be microsatellite instability high or DNA mismatch repair deficient, the art anticipates claim 1. We are not persuaded that claim 1 requires or excludes anything else because nothing else is recited in the claim.” slip op. at 10

      “Patent Owner does not direct us to evidence that it attempted to file any patent application before the publication date of the MSI-H clinical study and was denied an earlier filing date. Contrary to Patent Owner’s argument that it could not file a patent application without results from the MSI-H clinical study, we note that the inventors filed a provisional patent application on November 13, 2014, which, although also filed more than a year after the publication of the MSI-H clinical study, disclosed no clinical results or data. Ex. 1001, cover; Ex. 1030, 1. After considering the parties’ arguments, we are not persuaded by Patent Owner’s assertion that the inventors could not have filed an earlier application to at least attempt to secure a priority date before the MSI-H clinical study was publicly available. an earlier filing date. Instead, we are persuaded by Petitioner’s argument that because the MSI-H clinical study was published before the inventors filed an application to protect their patent rights the MSI-H clinical study is prior art for the information it discloses. Accordingly, we proceed to analyze Petitioner’s contentions in Ground 1.” slip op. at 24

PO Resp. 11–14. We are not persuaded that either the size of the genus in the MSI Study Record or whether one of ordinary skill in the art would have been able to envisage every species within it is dispositive of whether the MSI Study Record anticipates claim 1, where one of ordinary skill in the art would have known that specific cancers recited in claim 1 would be included in the MSI Study Record. As Petitioner argues, claim 1 requires that “a patient…selected from the group consisting of [the listed cancers]” be tested and treated. Pet. Reply 10 (emphasis original). Claim 1 does not require that the patient have each and every one of the sixteen listed cancers to anticipate the claim. Rather, claim 1 requires testing a sample from “a patient” with one of the recited types of cancer and treating the patient. See Brown v. 3M, 265 F.3d 1349, 1351 (Fed.

      “In contrast, the testimony of Patent Owner’s witness, Dr. Goldberg, supports Petitioner’s argument of the knowledge in the art at the time, wherein Dr. Goldberg testifies that “[w]hile many clinical oncologists were aware that patients with Lynch Syndrome had a defect in DNA mismatch repair, they associated MSI testing with young onset colorectal and endometrial cancer and patients with a family history of colorectal and/or endometrial cancer.” Ex. 2090 ¶ 79. Similarly, during his deposition, Dr. Goldberg also agreed that endometrial, gastric, and small-bowel cancers would come to mind when he saw a reference to MSI-high non-colorectal cancer. See Ex. 1243, 115:5–116:22 (Q. And so does endometrial cancer come to mind when you see reference to MSI-high non-colorectal cancers? . . . A. Yes. Q.

      “On balance, we find Petitioner’s evidence more persuasive of what one of ordinary skill in the art would have understood from the MSI-H Study Record. We find Dr. Neugut’s and Dr. Oberstein’s testimony, and Dr. Lonberg’s lack of clear testimony to the contrary, persuasive as to this issue. In addition, we are not persuaded by the case law cited by Patent Owner regarding inherent anticipation. See PO Resp. 6–7. Rather, we agree with Petitioner that the correct inquiry is whether the skilled artisan would have understood that all limitations are disclosed in the prior art. See Pet. 34–35; Pet. Reply 12–13. In light of the cited testimony, we are persuaded that Petitioner has met its burden of proving that a skilled artisan would reasonably have understood or inferred that the limitation for a patient having received a prior cancer therapy drug to treat the tumor was disclosed in the MSI-Study Record. Petitioner demonstrates what one of ordinary skill in the art would have understood from the MSI-H Study Record, not what it inherently discloses. Contra PO Resp. 6–9.” slip op. at 22

To Patent Owner, the ordinarily skilled artisan would have had a medical or graduate-level degree, or equivalent work experience, in the fields of immunology, genetics, or a related field and would have experience (i) conducting immunology research relating to oncology, (ii) conducting genetics research relating to oncology, or (iii) developing and conducting clinical trials on novel cancer therapies in those fields.

      “record, we are persuaded that the results recited in claim 1 would follow from the steps taught in the MSR, for the reasons and based on the evidence Petitioner cites above. For these same reasons, we are unpersuaded by Patent Owner’s argument that it was unknown whether the amount of pembrolizumab recited in claim 1 would be effective in producing an improved outcome compared to a reference patient without a tumor that was not MSI-H or dMMR, and Patent Owner does not dispute that the amount of pembrolizumab disclosed in the MSR (10 mg/kg every 14 days; see Ex. 1005, 4) is the same as the amount provided in the ’975 patent as being effective (10 mg/kg every 14 days; Ex. 1001, 8:48–52, 13:50–52). Regardless of the inventors’ intent in publishing the MSR as a Stage II clinical trial on the www.clinicaltrials.gov website, as discussed above, we determine that the MSR teaches selecting a patient with a metastatic MSI-H or dMMR tumor and administering an amount of pembrolizumab that would be effective. See, e.g., Ex. 1005, 4 (Arms and Interventions). The result of drug treatment inherently follows its administration. The MSR does not merely suggest that pembrolizumab may be useful in some unidentified subset of patients or suggest that some unidentified drug may be useful for MSI-H cancer patients. Instead, the MSR discloses selecting a patient with a condition recited in claim 1 and treating with the drug at the amount recited in claim 1. Contra Metabolite Labs. Inc. v. Lab. Corp. of Am. Holdings, 370 F.3d 1354, 1367 (Fed. Cir. 2004) (holding that the prior art did not inherently anticipate where it failed to mention specific vitamin deficiencies, instead merely inviting further experimentation to find associations with metabolic perturbations). requirement, efficacy is inherent in carrying out the claim steps,” referring to a claimed method of treating or preventing stroke, which was held to be anticipated by the publication of a proposed study. 677 F.3d at 1381. Patent Owner attempts to distinguish the size and apparent surety of the study in Montgomery from the MSR. PO Resp. 15. But because we find that the MSR teaches performing the steps recited in claim 1 for the purpose of determining and treating MSI-H cancer, we are persuaded that the MSR inherently discloses the results of selection of patients and administration of the drug treatment recited in those steps. See Bristol-Myers, 246 F.3d at 1376. Whether or not the MSR could have provided results or was sufficient for full regulatory approval does not change that the MSR teaches Patent Owner’s claimed steps. We have no reason to doubt that the disclosure in the MSR of the steps recited in claim 1 produces the efficacy element required in claim 1, whether or not this efficacy was disclosed in the MSR or was known when it was published.

      “use that does not qualify as prior art. PO Resp. 18–25. Patent Owner argues that an inventor can be granted latitude to experiment in the public eye until her invention is ready for patenting. Id. at 18 (citing Pfaff v. Wells Elecs., Inc., 525 U.S. 55, 64 (1998). According to Patent Owner, the experimental use negation applies to the MSR under a 13-factor analysis provided in Allen Engineering Corp. v. Bartell Industries, Inc., 299 F.3d 1336, 1353 (Fed. Cir. 2002). PO Resp. 19–25. For example, Patent Owner argues that to establish that treatment of MSI-H cancers was effective, the inventors had to test treatment in humans, there being no animal models, and had to publish the MSR on the government website under federal law. Id. at 20–22. Patent Owner argues further that the inventors had control over the MSI-H clinical study and that the field of cancer treatment was highly unpredictable, among other facts. Id. at 21. Patent Owner argues that “[a]t the time of the MSR’s posting, the claimed invention was not, nor could it have been, ready for patenting. The clinical study that ultimately collected the data reported in the patent specification and supporting the patent claims had not and could not have commenced before the MSR was posted.” Id. at 23. sometimes said that an inventor acquires an undue advantage over the public by delaying to take out a patent, inasmuch as he thereby preserves the monopoly to himself for a longer period than is allowed by the policy of the law,” but held that “when the delay is occasioned by a bona fide effort to bring his invention to perfection, or to ascertain whether it will answer the purpose intended,” the experiment use exception can preserve the inventor’s rights. City of Elizabeth v. Am. Nicholson Pavement Co., 97 U.S. 126, 137 (1877). Because we are not persuaded that Patent Owner could not have filed an earlier application, we are not persuaded that the experimental use doctrine is properly applied in this case. Given that clinical trial protocols published on the ClinicalTrials.gov website have been successfully asserted as prior art in other cases, we are not persuaded by Patent Owner’s arguments that the MSR is not available as prior art against the challenged claims.
