“We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012). The Technical Data Sheets may support a finding that the Xirallic® products they describe existed as of the dates on the documents, but they do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.” slip op. at 20

“witnesses. See Elbit Systems of Am., LLC v. Thales Visionix, Inc., 881 F.3d 1354, 1358 (Fed. Cir. 2018) (citing Trs. of Columbia Univ. v. Illumina, Inc., 620 F. App’x 916, 922 (Fed. Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

“Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

“A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A. Thus, for these additional reasons, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over Saxler, Beach, and Shenoy.” slip op. at 34

“remove the recess in Saxler Figure 1A to arrive at the allegedly enhancement mode transistor of Modified Figure 1A. Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68. Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A. Pet. 25, 40, 45. For example, Petitioner asserts that Saxler’s gate contact may be “recessed or non-recessed” and that when the gate recess shown in Figure 1A is not utilized, Saxler would have the structure of Saxler Modified Figure 1A. Pet. 25 (citing Ex. 1003 ¶ 81; Ex. 1007 ¶ 52, 66); see also Pet. 40, 45 (citing Ex. 1007 ¶ 52). Neither of these paragraphs provide sufficient motivation to a POSITA to remove the gate recess from Saxler Figure 1A. Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein.

Claims 1–5, 7–14, and 16 were not shown unpatentable because the asserted anticipation and obviousness grounds failed to establish the claimed thrust-bearing element and its required location.
RulingsFinal written decision- Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for patent owner
“We determine that the evidence of record overcomes the presumption that § 112, para. 6 does not apply because “thrust-bearing element” does not recite sufficiently definite structure in this case. See, e.g., Pet. 22 (the term is not used here according to its common meaning). First, the word “element” is a “[g]eneric term[]” or “verbal construct[]” often “used in a claim in a manner that is tantamount to using the word ‘means’” because it does not “connote sufficiently definite structure.” Williamson, 792 F.3d at 1350. We find nothing in the ’121 patent or elsewhere in the record suggesting that “element” in the term “thrust-bearing element” should be considered other than a generic placeholder term. Second, although the term “thrust bearing” may connote certain structure, “thrust-bearing element” does not. A “thrust bearing” is “a well-known term of art in engineering and is ‘a bearing which sustains axial loads and prevents axial movement of a loaded shaft.’” Ex. 1003 ¶ 46 (citing Ex. 1017, 2147). “The balls of traditional thrust bearings are positioned inline with the axial force, as thrust bearings are designed specifically to transmit axial load.” Id. Here, however, “thrust-bearing” is hyphenated, and is therefore a phrasal adjective modifying “element” rather than the noun phrase “thrust bearing.”8 Further, there are “substantial differences”” slip op. at 15
- Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Term construed board ownDecided for patent owner
“We largely agree with Petitioner. “[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.” B. Braun Med. Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed.Cir.1997). The Specification of the ’121 patent “clearly links or associates” two components with the function of bearing axial thrust from the sowing disc: shaft 27 with flanging 30, and thrust-bearing plate 31. Ex. 1001, 3:25–35. Thrust-bearing plate 31 is expressly described as “bear[ing] on that surface of the disc which faces seal 24 . . . in order to withstand at least some of the axial load produced by the disc 16 on the seal 24. Ex. 1001, 3:28–31. Rotatably-mounted shaft 27 with flanging 30 is “fixed” to thrust-bearing plate 31 and therefore bears the axial load from the disc via the thrust-bearing plate. Id. at 3:25–28.10 10 Drive element 32 is described as part of thrust-bearing element 26 and permits thrust-bearing element 26 to be driven in rotation with sowing disc 16. Ex. 1001, 3:36–40. It is not described as bearing any axial load, however. Further, it is not necessary for the thrust-bearing element to rotate with the sowing disc for that element to bear axial load from the sowing disc. See id. at 3:58–59 (“Provision is also made for the thrust-bearing element 26 to be made idle and not driven in rotation by the [drive] shaft 20.”). Ultimately, however, whether drive element 32 is properly considered as part of the corresponding structure is not relevant to the outcome of this case. We disagree with Patent Owner that bearings 28 and seat 29 should be considered corresponding structure. The Specification does not associate these structures with any axial load-bearing function. Instead, bearings 28 and seat 29 are described as the means by which, and the location in which, shaft 27 is rotatably mounted. Ex. 1001, 3:25–27. Regardless, whether or not bearings 28 and seat 29 are considered corresponding structure does not affect the outcome of this case. In summary, we construe “thrust-bearing element” as a means-plus- function claim term under 35 U.S.C. § 112, para. 6. Its recited function is to bear thrust, or more specifically to “withstand at least some of the axial load produced by the disc on the seal.” The structure described in the Specification as corresponding to this function is shaft 27 with flanging 30, and thrust-bearing plate 31. We construe the limitation as directed to this structure, and equivalent structures.” slip op. at 21

“The question is not whether the patentee disclaimed coverage over structures in which the thrust-bearing element is not located entirely in the movable portion of the housing. Instead, we must simply ascertain what the patentee meant by “supported rotatably in the movable portion.” To answer this question, we look to the Specification, which “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315. “The construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be, in the end, the correct construction.” Id. at 1316. Here, it is undisputed that in the sole embodiment described by the ’121 patent, the thrust-bearing element is supported by and entirely within the movable portion of the housing. Ex. 1001, Figs. 1, 2; Pet Post-Hearing Resp. 1; PO Post-Hearing Resp. 2. Construing “in the movable portion” to require the thrust-bearing element to be entirely within the movable portion both “stays true to the claim language and most naturally aligns” with the sole disclosed embodiment. Such a construction does not import the word “entirely” from the sole embodiment into the claims because the construction “arises from the claim language itself.” See SharkNinja Operating LLC v. iRobot Corp., 2024 WL 1132219, *2–*3 (Fed. Cir. 2024) (construing “primary brush assembly disposed within the round housing perimeter” to require that the primary brush assembly be “entirely within” the round housing perimeter is not an improper incorporation of “entirely” from embodiments into the claims because the construction “arises from the claim language itself”). Accordingly, having reviewed the complete record and the parties’ pre- and post-hearing briefing, we determine that “supported rotatably in the movable portion” means supported rotatably entirely in the space defined by the movable portion.” slip op. at 25

“b. When “Thrust-Bearing Element” is Construed as a Means-Plus-Function Claim Limitation, there is Insufficient Evidence in the Record to Support a Finding that VenHuizen Discloses a Thrust- Bearing Element that is Supported Rotatably in the Movable Portion As noted above, Petitioner contends that VenHuizen’s shaft 55, retaining hub 56, and handle 58 together constitute the claimed thrust-bearing element “under a proper means-plus-function definition.” Pet. Reply 18–19.12 We do not discern sufficient evidence of record or persuasive technical reasoning from Petitioner to support a finding that these elements together are “supported rotatably in the movable portion” of the housing, as claim 1 requires. Ex. 1001, 4:38–39. We construed this limitation to require the thrust-bearing element to be supported rotatably entirely in the space defined by the movable portion (the space defined by VenHuizen’s second housing member 90). Petitioner does not contend, much less show, that these components are supported rotatably entirely in the movable second housing member 90. On the contrary, of the three components constituting VenHuizen’s thrust-bearing element, all of retaining hub 56 and most of shaft 55 are located in the fixed portion of the housing (first housing member 50), not the movable portion 90. See Ex. 1001, Fig. 6. Only handle 58 is ever located in the movable portion (when the fixed and movable portions are joined together). See id.

“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

“combined Lee and Watanabe to achieve improved integration density. Pet. 71. Petitioner concedes, however, that the benefits of Lee’s design related to 3-D integration and improved integration density would be obtained if Lee’s memory structures are formed using either Lee’s monolithic construction method or Watanabe’s alternative stacking method. Pet. Reply 13–14 (citing Ex. 1041 ¶ 34). Thus, we are not persuaded that improved integration density provides a sufficient rationale for Petitioner’s combination of Lee’s memory device and Watanabe’s stacking method. Petitioner argues that Watanabe’s stacking method “improves the accuracy of the wiring” because the wiring is made “for each planar member.” Pet. 72 (citing Ex. 1005, 6:1–3). Watanabe also states that its disclosed methods provide “a low interconnection wire resistance.” Ex. 1005, 6:20–23. Petitioner does not, however, explain sufficiently how Watanabe’s stacking method would improve Lee’s device. For example, Petitioner does not address whether the alleged wiring benefit already existed in Lee’s monolithic array or explain how this benefit would also apply to Lee’s particular memory array, which differs in construction and elements from Watanabe’s device. This diminishes Petitioner’s benefits-based motivation to combine arguments. In general, a petitioner need not demonstrate that a particular alternate method would improve a prior art device in order to show a motivation to combine. Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023); see Pet. Reply 20 (citing Intel). But here, Petitioner affirmatively invokes improvement of Lee’s device as a reason for the combination, and we must evaluate Petitioner’s contention. Moreover, any relative lack of improvement or benefits must be weighed against any problems the alternative method would introduce. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 795–96 (Fed. Cir. 2021) (noting that simultaneous advantages and disadvantages to a proposed combination must be analyzed to determine whether the disadvantages “outweighed any reason to combine”). Here, as discussed above in more detail with respect to the ground based on Watanabe, the evidence shows that one of ordinary skill in the art would have expected Watanabe’s bonding temperature of 900– 1000° C to damage the electronic devices in an underlying substrate. Ex. 2029 ¶¶ 75–76; Ex. 2028, 123:13–124:7; Ex. 2027, 715. The expected damage to Lee’s device, when balanced against the limited evidence of a benefit to the combination,7 outweighs the reason to combine Lee and Watanabe set forth in the Petition. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious over Lee and Watanabe. 2.

“Ex. 1001, 6:28–38 (emphasis added). However, the language of claim 1 is very clear on the functionality of the “open tip,” expressly reciting that “the open tip cuts bone tissue away from the sacrum or the ilium.” Id. at 13:19– 20. Thus, the claim language itself provides the required functionality of the “open tip,” and we do not agree with Petitioner that additional functionality relating to where bone tissue might go once cut, as discussed in the Specification, should be read into the claims as a limitation. Patent Owner’s newly proposed interpretation is similar to Petitioner’s in that it requests addition of functionality discussed as an example in the Specification, but not recited in the claim’s expressly recited functional language relating to the “open tip.” We disagree with Patent Owner that the concept of dislodged tissue entering a void defined by the open tip is necessary to understanding the claim element. And, once more, Patent Owner reads too much structure from the written description into the claim language as a limitation because it is not apparent that the recited “open tip” language requires that we further clarify that any interior void defined by the open tip is on the interior of the abrading head, and behind the exterior abrading surfaces, or between interior surfaces of a first pair of opposing sides, as proposed by Patent Owner. “[W]hile it is true that claims are to be interpreted in light of the specification . . . , it does not follow that limitations from the specification may be read into the claims. . . .

“A claim limitation is presumed to invoke 35 U.S.C. § 112(f) (or pre- AIA § 112 ¶ 6) if, as here, it explicitly uses the term “means” and includes functional language; this presumption is overcome if the limitation further includes the structure, material, or acts necessary to perform the recited function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc). Here, the word “means” is recited, followed by functional language, and the claim recites no structure associated with the means or function. Moreover, the parties agree that this is a means plus function limitation. See Pet. 19–20; Resp. 9. We find “releasing means” is a means plus function limitation and, based on the plain language of the claim, the recited “releasing means” is a part of the also recited “slide hammer assembly,” as the above-quoted claim language defines. Ex. 1001, 13:10–17.

Patent Owner further argues, and we further agree, that the voltage across output leads 51 and 52 of Schulman is not an input to the external power source separate from the measured current through R9 in Schulman. See APO Sur-reply 11–16 (citing, e.g., Ex. 1003 ¶ 75; Ex. 2002 ¶ 46; Ex. 1005, 6:35–38; Ex. 2010 ¶¶ 4–7). In support of Patent Owner, Dr. Mihran states that “[t]he voltage between nodes 51 and 52 is never provided to the external power source in Schulman.” Ex. 2010 ¶ 4. According to Dr. Mihran, “Schulman discloses that the sole input provided to the external power source that the external power source uses to automatically regulate its power output is the input that derives from the amount of current flowing through the current sampling resistor R9.” Id. ¶ 5 (emphasis omitted) (citing Ex. 1005, 4:45–53, 6:35–38; Ex. 2002 ¶ 46). Dr. Mihran further states as follows: My understanding of Dr. Panescu’s opinion is that he does not contend that the voltage between nodes 51 and 52 is ever sent to the external power source as an input, and instead simply asserts that if “the voltage across leads 51 and 52 exceeds a predetermined amount,” then the current through R9 increases, which in turn “causes the power supplied by the external power source to decrease.” (Ex. 1012 at ¶16.) This does not represent a separate input, however, because the input derived from the current flowing through the current sampling resistor R9 (i.e. the load modulation frequency of telemetry circuit 12, the components of which “form a free-running multivibrator”) is what Dr. Panescu also identifies as satisfying the first input, “a value associated with said current passing through said internal battery.” (Ex. 1012 at ¶14 (“when the current through the internal battery . . . increases above a predetermined target value, the current regulator turns on, increasing the current through current sampling resistor R9.”) operating conditions may influence the value” of the amount of current flowing through current sampling resistor R9, and the current through R9 is the “only value that is communicated to the external power source,” corresponding to a single input that “cannot satisfy both of the two inputs required by claims 3, 6, 9, 12, 15, and 18 of the ’148 patent.” Id. ¶ 6. Dr. Mihran further states as follows: I understand Dr. Panescu’s opinion to be that, because Schulman discloses that the current through R9 is used by the external charger to automatically vary its output, any “value” that influences the amount of current through resistor R9 is a “separate respective input[] used by the external power source as a basis for automatically varying its power output.” ([Ex. 1012 ¶14].) In other words, Dr. Panescu simply identifies a voltage across two points in the circuit that he claims affects the current through R9 and contends that that voltage satisfies one of the two required separate inputs based on its alleged indirect impact on the output of the external charger. This strained interpretation of the claims renders superfluous the two separate inputs to the external power source required by claims 3, 6, 9, 12, 15, and 18 of the ’148 patent: (1) “a value associated with said current passing through said internal battery” and (2) “a signal proportional to said current passing through said internal battery” (claims 3, 9, and 15) and “measured voltage associated with said current passing through said internal battery” (claims 6, 12, and 18). In any circuit, there may be multiple components (e.g., transistors, switches, diodes, etc.) that can influence the current through a particular resistor. For example, in Schulman the current drawn by the stimulation portion of the implant circuit will influence the amount of current through R9. Dr. Panescu’s interpretation that a voltage or current at these components represents a “separate input” in Schulman is incorrect, because the sole input that is telemetered back to the external charger is the input derived from the amount of current flowing through R9.” slip op. at 35

Patent Owner argues that a person of ordinary skill “would have had at least a bachelor’s degree in a relevant field (e.g., electrical, mechanical, or biomedical engineering) with at least two years of experience with the design of components (e.g., circuitry) for implantable medical devices and associated external devices (e.g., a charging unit),” and that “[m]ore education can substitute for practical experience and vice versa.” PO Resp. 5 (citing Ex. 2002 ¶¶ 21, 22). Our analysis here, as in the FWD, does not turn on which of the Parties’ competing definitions of ordinary skill is applied. See FWD 16. Moreover, the appropriate level of ordinary skill is not in dispute on remand. Consistent with the FWD and the Decision on Institution, we apply the level of ordinary skill in the art proposed by Petitioner. See Inst. Dec. 11–12 (stating that “the ’758 patent and the cited prior art references reflect the appropriate level of skill at the time of the claimed invention and that the level of appropriate skill reflected in these references is consistent with the definition of a person of ordinary skill in the art proposed by Petitioner” (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001))); FWD 16.” slip op. at 17

“By contrast, in his Rebuttal Declaration, Dr. Mihran disputes Dr. Panescu’s new description of the operation of Schulman, noting that the current through R9 is not increased as a result of the current regulator R8/Q7 turning on, but that “[i]nstead, it is the increase in current through R9 in excess of the desired 40 mA operating current that causes the current regulator R8/Q7 to turn on, which acts to shunt this excess current through Q7, thereby diverting it away from the battery to maintain the desired operating condition during charging.” Ex. 2010 ¶ 6 n.2 (citing Ex. 1005, 5:2–7, 5:15–38, 9:57–68). We credit the testimony of Dr. Mihran, as supported by the cited portions of Schulman, over the unsupported testimony of Dr. Panescu in regard to how Schulman operates to measure current at R9. See id. However, whether Schulman discloses automatically varying the output power of the external power source based on a measured current, as required by the challenged claims, is not in dispute.

“We find that because it is largely unsupported and conclusory, the opinion of Dr. Panescu in his Supplemental Declaration that “Schulman teaches automatically varying the output power of the external power source based on a value, where the value is the voltage across the output leads 51 In his original declaration, Dr. Panescu made clear that, according to Schulman, the output of the external power source was lowered if the charging current, as measured at sampling resistor R9, “exceeds a maximum capacity,” not because of the voltage across output leads 51 and 52. See Ex. 1003 ¶ 127 (quoting Ex. 1005, 7:25–29). Petitioner does not allege that any measurement of voltage across output leads 51 and 52 in Schulman is conveyed to an external power source to automatically vary its power output. Instead, Petitioner’s argument is premised on the notion that if the voltage across leads 51 and 52 exceeds a predetermined amount, then it will affect the current sampled by resistor R9. We also find persuasive Dr. Mihran’s testimony that Petitioner’s strained interpretation renders the Value Limitation superfluous to the Measured Current Limitation because the voltage across leads 51 and 52 was not shown by Petitioner to be a separate input to the external power source. See Ex. 2010 ¶ 7 (explaining that “there may be multiple components (e.g., transistors, switches, diodes, etc.) that can influence the current through a particular resistor,” and that influencing the current measured at R9 does not constitute a separate input to the external charger from the measured current at R9). To be clear, we need not resolve whether the challenged claims require each separate input be separately conveyed to the external power source. Here, the burden to show anticipation is on Petitioner and Petitioner offers no persuasive evidence or explanation to establish by a preponderance of the evidence that a person of ordinary skill in the art would have understood the voltage across output leads 51 and 52 corresponds to “a value” based upon which the external power source “automatically” varies its power output, as required by the challenged claims. Nor does skill in the art would have understood the voltage across leads 51 and 52 in Schulman to be a separate input from the measured current at R9 when, at most, Petitioner alleges the voltage across leads 51 and 52 may, in certain circumstances, have some effect on the measured current at R9, itself. Thus, Petitioner does not show by a preponderance of the evidence that Schulman discloses to a person of ordinary skill in the art two separate inputs to the external power source, as Petitioner conceded is required by the Value Limitation and the Measured Current Limitation.” slip op. at 35

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“Based on the information above, we conclude that the limitation “a groove that is laterally offset from the chamfered mandrel” requires the groove to be entirely to the side of any part of the mandrel. This construction is consistent with the words of the claim—the claim states that the groove is laterally offset from, or to the side of, the chamfered mandrel, not merely offset from a portion of or the centerline of the mandrel. This construction is also consistent with the one embodiment describing the relationship between the mandrel and groove containing the seal, which depicts the groove entirely to the side of the chamfered mandrel. We do not accept Mr. Jobin’s testimony that laterally offset is determined relative to the centerline of an object. Neither the intrinsic record nor other extrinsic evidence provides support for Mr. Jobin identifying the centerline of an object as the reference point for determining if a point is laterally offset from the object.” slip op. at 31

“We do not agree with Petitioner that Yoakim teaches a groove that is laterally offset from the chamfered mandrel. As we indicated in our claim construction section, we construe the claim term to require the groove to be entirely to the side of any part of the mandrel. We agree with Patent Owner that, as depicted in Yoakim’s Figure 35, the alleged groove is not entirely to the side of any part of the mandrel. See Pet. 69; see also Pet. Reply 19 (showing the alleged groove, in red, including a portion over the chamfered mandrel); PO Resp. 55 (same). Even if Petitioner’s position is that all of the groove must be to the side of the centerline of the mandrel, Petitioner fails to prove that Yoakim teaches such a structure. As seen in Petitioner’s illustration at page 19 of Petitioner’s Reply (reproduced above), a small portion of the groove (which Petition colorizes in red) is to the left of the centerline (shown in green). See Pet. Reply 19.” slip op. at 40
