    “target value” is part of a command that is sent from a computing device to a server and then to a controller. The controller then receives a measurement of the fluid by a sensor and determines whether the measurement satisfies the “target value.” If the measurement does not satisfy the “target value,” further operations are undertaken. The recited operation sequence makes clear that the plain and ordinary meaning of “target value” is not as Dr. Wooley opines because the particular operating condition that a device is in at a particular time is represented by the measurement taken by the sensor, 11 Some claim language less relevant to construing “target value” was omitted for ease of reference. which the controller then uses to determine whether the measurement satisfies the “target value.” Additionally, claim 1 recites that the “target value” is sent as part of a command to the controller. The “target value” is not sent to the controller from the sensor, as might be expected if the plain and ordinary meaning of “target value” were as Dr. Wooley opines. Petitioner and Dr. Wooley’s construction would also result in “target value” meaning effectively the same thing as the measurement of the fluid by the sensor, a concept that is separately recited in claim 1 and to which the “target value” is compared. The Specification of the ’680 patent does not support Petitioner’s understanding of the plain and ordinary meaning of “target value.” Although the Specification does not recite “target value,” it recites “target state,” and describes “target state” sufficiently to understand the plain and ordinary meaning of “target” as used in “target value” and “target state.” In particular, the ’680 patent explains that “[i]n some embodiments, the process 104 includes receiving, via a network interface, from a remote user device, (e.g., via a command-center server) a command to change a state of a fluid-handling device to a target state.” Ex. 1001, 11:48–51. This portion reflects that the command is seeking to change a state of a fluid-handling device to a target state. In other words, the “target value” or “target state” is not generally “the particular operating condition that a device is in at a particular time”; rather, it is a value or state that the fluid-handling device is desired to be in, as Patent Owner and Dr. Durham explain. Additionally, just as claim 1 recites a directional component for the “target value” to be sent to the controller in a command, so too does the Specification describe a “target state” as being sent in a command from a remote user device. Thus, the Specification clearly supports the plain and ordinary meaning proposed by Patent Owner and Dr. Durham and not the plain and ordinary meaning proposed by Petitioner and Dr. Wooley. slip op. at 14

Almadi explains that its remote field systems must include a plurality of controller units “to issue commands to, and gather and process data from a plurality of field devices, including remote systems and instruments, . . .

Based on these disclosures, we agree with Patent Owner that Petitioner has not established that Almadi discloses element [1.4]. Specifically, the teachings from Almadi identified by Petitioner refer to process data, which is data retrieved from the remote subsystems/field devices. Thus, we understand that Almadi’s teaching—of using an Ethernet switch to transmit “process data”—describes transmitting data from the remote subsystems/field devices. See Ex. 1005, 3:13–17, cited in Pet. 15. But claim 1 and particularly element [1.4], recites “sending, with the server, the target value to the network address [which identifies a controller of the fluid-handling device13] via the network,” which is different than sending process data from the field devices to the remote host or database server for storage.” slip op. at 19

Based on this express definition, the current record does not support the interpretation proffered by Patent Owner and Dr. Triggs-Raine that the “term ‘modified PH20 polypeptide,’. . . has a purely structural meaning in the context of the specification.” Prelim Resp. 21 (citing Ex. 2055 ¶ 68). Patent Owner and its declarant rely on a truncated version of the definition above that omits the text after the first period because, in their view, that text “is not part of the express definition of ‘modified PH20 polypeptide’” and “merely describes an upper limit for the number of modifications possibly allowing a modified PH20 polypeptide to exhibit enzymatic activity.” Ex. 2055 ¶¶ 67, 77–78 (emphasis in original). On this record, we disagree. We find that this text is part of the definition of “modified PH20 polypeptide” because it continues to detail specific elements required of that term, i.e., a requirement that modifications in the PH20 polypeptide are permitted “so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Ex. 1001, 48:47–49 (emphasis added); see Ex. 2055 ¶ 67 (acknowledging that a “patent’s definition controls,” but referring, without adequate explanation, to the second sentence of the definition paragraph as “a non-limiting example”). Indeed, while some of the language in the definitional paragraph is permissive in nature, i.e.., describing the number of amino acid replacements a modified PH20 polypeptide “can have” or “[t]ypically . . . contains” or the other modifications the polypeptide “can include,” the phrase “so long as” is not. See Ex. 1001, 48:41–56. This distinction demonstrates that hyaluronidase activity is not an optional feature of a non-limiting example as Patent Owner posits, but a requirement of the “modified PH20 polypeptide” defined and claimed in the ’652 patent. See Alynylam Pharms., Inc. v. Moderna, Inc., 138 F.4th 1326, 1333 (Fed.

    “Thus, the ’520 patent evidences that even when only a single mutation is made in the PH20 polypeptide, that single mutation is more likely than not to alter the structure in such a way as to inactivate the hyaluronidase activity found in the native PH20 polypeptide. On this record, Dr. Hecht persuasively demonstrates that when the full scope of claim 1 is addressed, which includes not just single mutations in the PH20 polypeptide, but also multiple mutations, there is no expectation of structural homogeneity, stating that “[i]ntroducing multiple amino acid changes simultaneously . . . could prevent the folding of sequences into secondary structures and structural motifs and can destabilize those structures if they do form.” Ex. 1003 ¶ 59. Dr. Hecht notes that claim 1 allows “21-42 changes, with each additional change (except at position 324) being to 1 of 19 other amino acids. But the up to 21-42 changes also can be at any of between 430 and 465 (or, in the case of the broadest claims, 474) different positions depending on which unmodified PH20 sequence is used.” Id. ¶ 120. Dr. Park calculates that “95% sequence identity to PH201-465 means that the protein can have 23 total changes,” and that where one of those changes is one of five choices at position 324 as required by claim 1, the number of possible PH20 polypeptides with twenty-two additional changes is “extremely large by all accounts, ranging from 1059 to 10112.” See” slip op. at 27

    “In addressing the level of ordinary skill in the art, Petitioner contends that a person of ordinary skill in the art (“POSA” or “POSITA”) would have had at least a Ph.D. in biochemistry, molecular biology, or a related field and between one and four years of post-doctoral experience in the field of gene therapy. Alternatively, a POSA would have had at least a Master’s or Bachelor’s Degree in biochemistry, molecular biology, or a related field, with a corresponding number of additional years of experience in the field of gene therapy. Pet. 12 (citing Ex. 1005 ¶¶ 111–115). Patent Owner states that it does not challenge Petitioner’s definition. PO Resp. 10. On this complete record, we accept Petitioner’s proposed definition, as it appears consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’274 Patent.

    “According to the import of the complete recitation of paragraph 250 of the ’772 Publication set forth above that Petitioner relies upon for the motivation to improve efficient gene transfer in liver, AAV8 already fulfills this need. See Tr. 28:15–18. We do not read the ’772 Publication as calling for a search for a more efficient variant to improve efficient gene transfer in liver. We credit Dr. Samulski’s testimony that supports this view of the teachings of the ’772 Publication. Dr. Samulski testifies: Additionally, when the inventors compared AAV8’s expression in the liver against new serotypes AAVrh2, AAVrh10, AAVrh13, and AAVrh21, they found that AAV8 remained superior: EX1007, ¶ 253. Notably, AAV8 was shown to have over fifty percent (50%) greater expression in liver than AAVrh10. As I discuss more below, a skilled artisan in 2005 would not have expected a single amino acid substitution to significantly alter tropism in order to target to a different tissue. Thus, in my opinion, in 2005, a skilled artisan with the goal of targeting the liver would have selected the best known vector for delivery to liver at that time—AAV8. Ex. 2027 ¶ 42. We also agree with Dr. Samulski’s opinion that a POSA would have selected the best vector for liver, AAV8, instead of modifying another vector to increase tropism to liver. Dr. Samulski testifies: In my opinion, a skilled artisan in 2005 would not have looked solely to modify a vector to try to improve tropism to a particular tissue. As discussed throughout this declaration, changing tropism is difficult to predict, and a skilled artisan would not have had a reasonable expectation that changes could be made to improve or alter tropism. A skilled artisan would also have been concerned that changes, even small ones, could negatively impact other properties of the capsid protein. Therefore, rather than seek to modify a vector, a skilled artisan” slip op. at 29

    “The ’772 Publication, however, does not indicate as Petitioner asserts that a new variant is necessary to improve the efficiency of gene transfer to liver; the ’772 Publication indicates that AAV8 fulfills that need. See Ex. 1007 ¶ 250. In the paragraph that Petitioner relies upon for the alleged need to improve the efficiency of gene transfer to the liver, the ’772 Publication states in full: The tropism of each new vector is favorable for in vivo applications. AAV2/7 vectors appear to transduce skeletal muscle as efficiently as AAV2/1, which is the serotype that confers the highest level of transduction in skeletal muscle of the primate AAVs tested to date. Importantly, AAV2/8 provides a substantial advantage over the other serotypes in terms of efficiency of gene transfer to liver that until now has been relatively disappointing in terms of the numbers of hapatocytes stably transduced. AAV2/8 consistently achieved a 10 to 100-fold improvement in gene transfer efficiency as compared to the other vectors. The basis for the improved efficiency of AAV2/8 is unclear, although it presumably is due to uptake via a different receptor that is more active on the basolateral surface of hepatocytes. This improved efficiency will be quite useful in the development of liver-directed gene transfer where the number of transduced cells is critical, such as in urea cycle disorders and familial hypercholesterolemia.

    “Based on the record before us, including the types of problems and solutions described in the ’077 patent and the cited prior art, we find a POSA would have had (1) a Doctor of Medicine (M.D.) or at least a bachelor of science degree in biomedical engineering or a related discipline, (2) at least three years of experience in the clinical use, design, development, and/or testing of medical devices that deliver energy to tissue, and 3) knowledge and experience in treating nasal conditions, or access to a person with that knowledge and experience. Less work experience may be compensated by a higher level of education, and vice versa. 11 Patent Owner suggests a POSA’s ability to “learn about” the nasal anatomy invokes the wrong standard because a POSA “must have the necessary background at the time of the invention.” PO Sur-reply 27. We agree in part with Patent Owner; the hypothetical POSA is presumed to possess the requisite skill at the time of the invention. Nevertheless, as it concerns an engineer with extensive experience designing and developing RF ablation devices (like Dr. Martin), we see no basis to conclude that such person may not become familiar with the features of the nose through review of the literature and/or consultation with clinicians. Ex. 1098 ¶ 44 (testifying a person with device design experience could learn about the relevant nasal anatomy and apply their skill to problems or solutions for that area by reviewing the relevant literature). Moreover, that Dr. Martin may not have had personal experience designing devices for the nose prior to 2006 does not mean that he cannot testify from a POSA’s perspective. Osseo Imaging, LLC v. Planmeca USA, Inc., 116 F.4th 1335, 1341 (Fed. Cir. 2024) (“An expert need not have acquired the skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art” because “an expert can acquire the necessary skill level later and develop an understanding of what a [POSA] knew at the time of the invention”) (emphasis omitted). Petitioner that the ’077 patent discloses delivering neurotoxins to any target, and not just the nose, the claims of the ’077 patent are directed to methods of treating a nasal condition by delivering energy to the nasal cavity. Pet. Reply 32. Thus, to fill a gap between Petitioner’s POSA definition and the scope of the challenged claims, we add to Petitioner’s definition the requirement for knowledge and experience in treating nasal conditions, or access to a person with that knowledge and experience. We additionally add that a POSA’s educational background may include a bachelor of science degree in biomedical engineering or related discipline to reflect the nature of the field of invention. Nonetheless, we also note that our analysis and conclusions herein would not change even under Petitioner’s proposed skill level for a POSA. We do not agree with Patent Owner that prior experience designing or developing nasal medical devices is required for a POSA. PO Resp. 19–20. A definition inclusive of the clinical use, design, development, and/or testing of nasal medical devices that deliver energy to tissue is consistent with the skill level reflected in the disclosures of the ’077 patent and prior art. Consequently, we disagree with Patent Owner that Dr. Bu-Saba fails to qualify as a POSA because he lacks experience specific to designing medical devices. PO Resp. 19 n.4. We also disagree that Dr. Martin’s testimony should be discounted for a lack of first-hand experience designing RF ablation devices specific for the nose (which experience Patent Owner’s engineer expert also lacks).
