“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.

“Regarding the dependent claims that Petitioner challenges only on obviousness grounds (claims 3, 8, 13, 18), Patent Owner must show a nexus between the claimed methods and the evidence of non-obviousness. See Henny Penny Corp. v. Frymaster LLC, 938 F.3d 1324, 1332 (Fed. Cir. 2019) (“to be accorded substantial weight in the obviousness analysis, the evidence of secondary considerations must have a ‘nexus’ to the claims, i.e., there must be ‘a legally and factually sufficient connection’ between the evidence and the patented invention. . . . Ultimately, ‘[t]he patentee bears the burden of showing that a nexus exists.’” (quoting Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988), WMS Gaming, Inc. v. Int'l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999)). Patent Owner does not direct us to evidence of a nexus to limitations recited in the dependent claims, for example to claims 3 and 13, which recite testing a biological sample that is a bodily fluid, claims 8 and 18, which recite testing that comprises assessing one or more markers selected from the group consisting of BAT-25, BAT-26, MONO-27, NR-21 and NR-24. Even if there is a nexus to the Patent Owner’s evidence of secondary considerations, the evidence addresses the methods of independent claims 1 and 11, not the limitations of the claims Petitioner challenges as being obvious. PO Resp. 55–83. Patent Owner directs us only to evidence regarding treating patients determined to have certain MSI-H cancers with pembrolizumab, which we determine to be anticipated by the MSR. Id. at 58. When evidence of a “secondary consideration is exclusively related to a single feature that is in the prior art,” our reviewing court has held the evidence is of no relevance to the obviousness inquiry. See Yita LLC v. MacNeil IP LLC, 69 F.4th 1356, 1363–65 (Fed. Cir. 2023), cert. denied, 144 S. Ct. 499 (2023) (distinguishing WBIP, LLC v. Kohler Co., 829 F.3d 1317, 1330–31 (Fed. Cir. 2016)); see also Ethicon Endo-Surgery, Inc. v. Covidien LP, 812 F.3d 1023, 1034 (Fed. Cir. 2016) (“[I]f the feature that creates the commercial success was known in the prior art, the success is not pertinent.”). In Yita, the prior art taught close-conformance of a floor tray with the walls of a vehicle foot well, which one of ordinary skill in the art would have had reason to use in combination with other prior-art teachings to arrive at the claimed invention. See Yita, 69 F.4th at 1359–61. The court held that because the asserted evidence of secondary consideration related exclusively to close-conformity, the evidence was not persuasive of non-obviousness, even though the claimed floor tray was coextensive with the product that produced the evidence. See id. at 1364–65 (“The coextensiveness inquiry bears only on the presumption of nexus; it does not decide the overall nexus question.”). Because Patent Owner directs us only to evidence that the methods recited in claims 1 and 11 produced evidence of secondary considerations, we are not persuaded that this evidence is persuasive of the non-obviousness of the specific methods recited in the dependent claims. For example, Patent Owner fails to direct us to evidence that a method of treating MSI-H colorectal cancer in a patient “wherein the biological sample is a body fluid from the patient,” as recited in claim 3, or “wherein the at least one marker comprises BAT-25, BAT-26, MONO-27, NR-21 or NR-24,” as recited in claim 8, demonstrated unexpected results or commercial success. Accordingly, having considered the evidence of record as a whole, we determine that Petitioner has demonstrated by a preponderance of the evidence that the methods of claims 3, 8, 13, and 18 would have been obvious. We are not persuaded to the contrary by Patent Owner’s arguments or evidence of second secondary considerations.” slip op. at 47

“Petitioner and Patent Owner characterize one of ordinary skill in the art differently. To Petitioner, the ordinarily skilled artisan would be a medical doctor, or a professional in a related field, with experience treating cancer or access to those with experience in clinical studies of therapeutics and to a pathologist with this experience. (See Pet. 11 (citing Ex. 1003 ¶ 19).) 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. (See PO Resp. 5–6 (citing Ex. 2072 ¶¶ 31–32, 91–99).) Petitioner emphasizes medical and treatment aspects in its characterization of an ordinarily skilled artisan, whereas Patent Owner emphasizes research aspects. The ’491 patent claims a method of treating a human patient with cancer having certain characteristics using pembrolizumab and the main prior art reference cited by Petitioner discloses testing pembrolizumab to treat human patients. (See Ex. 1001, 25:36–52, 26:24–41, Ex. 1005; see Decision 8–9.) Accordingly, the relevant field of Patent Owner’s claims is treating human patients, as well as testing existing compounds. In light of the extent of the relevant field, we determine that the level of skill in the art relevant to the claims of the ’491 patent is not limited to knowledge of and experience with conducting research relating to oncology or developing and conducting clinical trials, but includes knowledge of and experience with treating cancer patients with immunotherapy compounds, identifying the conditions these patients may have, and understanding the literature regarding clinical trials for such colorectal cancers and the associated conditions and immunotherapy.

“Dr. Lonberg, Patent Owner’s witness, does not dispute any of Dr. Neugut’s or Dr. Oberstein’s testimony, but asserts only that Dr. Neugut’s testimony relies only on what was generally done, not on what is expressly disclosed in the MSR. (See Ex. 2072 ¶¶ 105–107.) On cross-examination, Dr. Lonberg agreed with Dr. Oberstein that patients who had received prior cancer therapy were not excluded from the study described in the MSR. (See Ex. 1245, 57:5–58:2, 40:5–14, 49:2–12.) Thus, after considering the evidence cited by each party, we find Dr. Neugut’s and Dr. Oberstein’s testimony to be the most directly relevant and persuasive about what one of ordinary skill in the art would have understood from the MSR itself. We are also persuaded by the lack of a specific contradiction regarding the understanding of one of ordinarily skill in the art by Dr. Lonberg. Even if some patients who had been previously treated with specific drugs were excluded from the study described in the MSR, we are persuaded that one of ordinary skill in the art would have understood the MSR as including other patients who have been treated with a prior cancer therapy drug. We are persuaded that Petitioner has met its burden of proving whether a skilled artisan would reasonably understand or infer that the limitations of claims 13, 28, 32, and 36 were disclosed in the MSR.

“Patent Owner argues that the “in response to” limitation of claim 1 describes administering the claimed treatment only to patients determined to have an MSI-H tumor. (See PO Resp. 6.) But neither claim 1 nor claim 16 includes a limitation excluding the treatment of any patient, such as specifically excluding treatment of any patient who has a tumor that is not MSI-H or dMMR. Neither claim 1 nor claim 16 recites any language differentiating between patients or identifying a patient population to be excluded from treatment. Instead, claims 1 and 16 provide that if the colorectal cancer patient is tested and the cancer is determined to be MSI-H or dMMR, the patient is treated with a therapeutically effective amount of pembrolizumab. We note that the methods of claims 1 and 16 use the open-ended transitional phrase “comprising” that is generally interpreted to not exclude additional, unrecited elements. See Invitrogen Corp. v. Biocrest Mfg., L.P., 327 F.3d 1364, 1368 (Fed. Cir. 2003) (“The transition ‘comprising’ in a method claim indicates that the claim is open-ended and allows for additional steps.”); Genentech, Inc. v.

The use of the open-ended transitional phrase “comprising” in claims 1 and 16 further suggests to us that any additional steps taken in conjunction with expressly recited method steps, such as the treatment of patients who are not MSI-H or dMMR, are not excluded from the scope of the claim.” slip op. at 13

Although Patent Owner argues that a missing element cannot be filled by what an ordinarily skilled artisan would have envisioned, Petitioner’s argument is based on what one of ordinary skill in the art would have understood from what the MSR expressly teaches. (See Pet. 20 (“Indeed, prior art concerning the MSI-H Study indicates that the physicians understood postings on clinicaltrials.gov indicated that patients had ‘metastatic tumors.’ (EX1049, 444; see also EX1050, S4; EX1003, ¶62.)”).) Unlike the facts of Nidec, where a missing signal could have been envisioned but was not present, we are persuaded by the evidence Petitioner presents that those of ordinary skill in the art understood the MSR express disclosure to include patients with unresectable or metastatic tumors because references referring to the study underlying the MSR discuss the inclusion of patients with metastatic tumors in the study. Even if Dr. Neugut’s reasoning that the reference to “measurable” disease in the MSR would have indicated patients having metastatic cancer is flawed, we are persuaded by Petitioner’s evidence of publications referring to the MSR as a study of metastatic colorectal cancer, and we are further persuaded that one of ordinary skill in the art would have understood the MSR to disclose treating patients having metastatic colorectal cancer with pembrolizumab. (See Ex. 1049, 444, Ex. 1050, S4.) Patent Owner does not address this evidence. Instead, Patent Owner acknowledges that “the MSR discloses treating cancer patients that could be within the claimed subset,” but argues that the MSR does not inherently anticipate results later obtained by treating only patients within the claimed subset. (See Pet. Sur- Reply 5–6.) We are persuaded, though, that Petitioner’s challenge is based on what one of ordinary skill in the art would have understood from the MSR (that patients who had an unresectable or metastatic tumor were selected), not on what is inherent to the disclosure of the MSR. We are persuaded that one of ordinary skill in the art at the time would have understood the MSR to teach selecting a patient “who has an unresectable or metastatic,” as required in claim 1. c) Element 1.2: “microsatellite instability-high (MSI-H) or mismatch slip op. at 14

“Patent Owner argues further that the MSR discloses an experimental use that does not qualify as prior art. (See PO Resp. 16–23.) Patent Owner argues that an inventor can be granted latitude to experiment in the public eye until her invention is ready for patenting. (See id. at 16 (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 Eng'g Corp. v. Bartell Indus., Inc., 299 F.3d 1336, 1353 (Fed. Cir. 2002). (See PO Resp. 17–23.) 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. (See PO Resp. 18–20.) 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. (See id. at 19–20.) 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 21.) In City of Elizabeth, the Supreme Court was concerned that “[i]t is 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.

“(Ex. 1001, 26:19–28.) In Grounds 3 and 5, Petitioner argues, relying on Dr. Neugut’s testimony, that Chapelle teaches standard methods of testing whether a tumor is MSI-H, including determining whether the patient’s tumor exhibits instability in a microsatellite marker, such as BAT-25 or BAT-26. (See Pet. 42 (citing Ex. 1007, 3380, 3383; Ex. 1003 ¶ 107).) For example, Chapelle states that “‘a standard test’ using a ‘[p]anel consisting of … BAT26, BAT25’ has ‘stood the test of time.’” (Ex. 1007 at 3382.) Dr. Neugut testifies that one of ordinary skill in the art would have been motivated to treat a patient with an unresectable or metastatic MSI-H dMMR tumor, wherein the tumor exhibits instability in the BAT-25 and BAT-26 microsatellite marker, and would have expected success in doing so, in light of the teachings of Chapelle.

“Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” is too narrow. Although Patent Owner points to various parts of the ’518 patent as supporting its restrictive proposal, other parts of the patent are not so limited. For example, the patent’s technical field and summary are not limited to coaxial cable, and the patent discusses twisted pair wiring and satellite communications as media that can be used. See, e.g., Ex. 1001, 1:27–29, 3:33–35, 3:49–50, 3:67–4:3, 5:61–6:3, 8:20–23, 9:28–33. Accordingly, we adopt the following level of ordinary skill in the art for use in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to four years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find that this skill level is consistent with the problems and solutions identified in the ’518 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

“We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed.

“We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra.

“We do not agree with Petitioner’s obvious to try theory because Petitioner does not show that the “few finite options” were known in the prior art. However, we nevertheless agree with Petitioner that it would have been obvious for the cable modem engine to have been configured to enable upgrades to its software in a manner that is independent of upgrades to the software of the data networking engine. This is primarily because this limitation appears to require little more than that a software update could change the cable modem functionality (e.g., the PacketCable or DOCSIS functionality) without changing the data networking engine functionality (e.g., the CableHome functionality). See Ex. 1001, 3:49–62. Gaspar, for example, shows that one of ordinary skill would recognize that the evolution of standards in this field requires controller upgrades, and a software update addressing only a change in the PacketCable standard (because only that standard had changed, for example) would be an upgrade to the cable modem software that would be independent of any upgrades to data networking engine software.
