“that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. In this case, we must determine whether one of ordinary skill in the art would recognize that Hangzhou’s disclosure of driving its auto-guided trolleys 200 under shelves 100 would improve the operation of Raizer’s system in the same way. For us to resolve this question in Petitioner’s favor, Petitioner must provide “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” Id. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed.

“For the following reasons, we determine that the portions of the prosecution history of the ’650 patent relied on by Patent Owner do not “prov[e] the existence of a ‘clear and unmistakable’ disclaimer that would have been evident to one skilled in the art.” Trivascular, 812 F.3d at 1063– 64.14 Patent Owner argues that the prosecution history redefined the term forward “by disclaiming workstations that are mounted on top of or over the height adjustment mechanism.” PO Resp. 29. Claims 3 and 4 recite “a work platform including a work surface and compartments for containing items” not a “workstation.” It is unclear what Patent Owner is referring to as the “workstation,” i.e., the recited “work platform,” the recited “work surface,” or the combination of “work platform,” “work surface,” and the recited “compartments.” Patent Owner injects further ambiguity by rephrasing the disclaimer, as “Applicant explicitly disclaimed carts having work stations mounted entirely to the top of the height adjustment mechanism (e.g., carts like Clark and Reeder).” Id. at 30 (emphasis added). Regardless of these 14 Because of our determination that the requirements for a clear and unmistakable disclaimer are not met by the cited portions of the prosecution history of the ’650 patent, we need not and do not reach the question of relevance of the statements in the prosecution of the ’650 patent to the claims of the ’668 patent. ambiguities, Patent Owner misinterprets the statements in the prosecution history. The applicant’s primary argument was that an ordinarily skilled artisan would not have incorporated moveable work surfaces above the “compartment” of Clark. Ex. 1033, 137–38.

As noted above, the underlying premise of Patent Owner’s proposed construction is that the language “disposed in” is broad enough to encompass compartments not “entirely in” or “contained in” the recited portion of the work platform. We start our analysis with the claim language. Claim 1 recites “wherein the work platform includes a portion projecting, relative to the height adjustment mechanism, in a forward direction . . . the compartment is disposed in the portion of the work platform projecting in the forward direction.” Ex. 1001, 14:39–43. By reciting “a portion projecting, relative to the height adjustment mechanism,” the claim language implies that the entire work platform is not required to project in the forward direction. We also note that nothing in claim 1 requires any particular size of the compartment. The only recitation in the claim regarding location of the compartment is that it “is disposed in the portion of the work platform projecting in the forward direction,” but that language on its face does not require or suggest that the compartments are “entirely in” or only “contained in” the recited portion of the work platform. In other words, nothing in the claims expressly restricts the compartments from being disposed in the “portion” recited as well as another portion of the work platform that does not project in the forward direction.

“The District Court’s Claim Construction Order (Ex. 2032) issued after our Institution Decision (Paper 11).

“We agree with Petitioner’s contention that “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” See Reply 2. The ’054 patent states In certain embodiments, the device contains a high density Flash memory with a low density DRAM, wherein the DRAM is used as a data buffer for read/write operation. The Flash serves as the main memory. Ex. 1001, 11:3–6 (emphases added). This is the only mention of “main memory” in the ’054 patent. That the Flash memory serves as “main memory” in “certain embodiments” implies that there may be other embodiments in which this is not the case. Accordingly, we agree with Petitioner that the term “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” We agree with Patent Owner that the “memory module” includes structure to connect with a “host system” including its memory controller. See, e.g., Ex. 1001, code (57), 12:52–59. The claims do not mention a “memory controller,” but they do mention that the “memory module” has an “interface” to connect with a “host system.” Ex. 1001, 38:20–25 (claim 1), 39:63–65 (claim 16), 41:6–8 (claim 24). That the “memory module” has structure for connecting to the host system’s memory controller may thus be implied from the claims. We agree with Petitioner that the District Court’s determination was that the preambles (presumably of claims 1, 4, 6, 11, 16 and 25) are limiting. Ex. 2032, 35. To the extent that the District Court’s determination construed “memory module” to include structure necessary to connect to a memory controller, our construction of “memory module” is consistent.” slip op. at 16

The prior art may reflect an appropriate level of skill. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001). Petitioner asserts a person of ordinary skill in the art “would have had an advanced degree in electrical or computer engineering, or a related field, and two years working or studying in the field of design or development of memory systems, or a bachelor’s degree in such engineering disciplines and at least three years working in the field.” Pet. 7–8 (citing Ex. 1003 ¶ 61). Petitioner contends that additional training can substitute for educational or research experience, and vice versa. Id. at 8. Petitioner asserts that such a hypothetical person would have been familiar with the JEDEC industry standards, and knowledgeable about the design and operation of standardized DRAM and SDRAM memory devices and memory modules and how they interacted with a memory controller and other parts of a computer system, including standard communication busses and protocols, such as PCI and SMBus busses and protocols. Id. Petitioner further contends that such “a hypothetical person would also have been familiar with the structure and operation of circuitry used to access and control computer memories, including sophisticated circuits such as ASICs, FPGAs, and CPLDs, and more low-level circuits such as tri-state buffers.” Id. Petitioner further asserts that such “a hypothetical person would further have been familiar with voltage supply requirements of such structures (e.g., memory modules, memory devices, memory controller, and associated access and control circuitry), including voltage conversion and voltage regulation circuitry.” Id. Patent Owner indicates “[f]or the purposes of this [Response], Patent Owner is applying the level of ordinary skill in the art proposed by Petitioner.” Resp. 2. The evidence that Petitioner presents mostly applies to the educational level and experience of workers in the field, but also touches upon other factors as well, including problems and solutions in the prior art and complexity of the technology. See Pet. 7–8. We find Petitioner’s proposal is consistent with the level of skill in the art reflected by the ’054 patent and the prior art of record, and, therefore, we adopt Petitioner’s proposed level of ordinary skill in the art, with the exception of the open-ended language “at least,” which introduces ambiguity and may encompass skill levels beyond ordinary.” slip op. at 11
- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner
“The District Court’s Claim Construction Order (Ex. 2032) issued after our Institution Decision (Paper 11). Although Petitioner argued in the District Court litigation that the claim preambles were not limiting, Petitioner does not appear to maintain that argument here following the District Court’s determination that the preambles are limiting. Ex. 2032, 35. Since the term is recited in both the preambles and bodies of these claims, there is evidence that the inventors of the ’054 patent intended the term to limit the claim, as the District Court determined. See Catalina Mktg. Int’l., Inc. v. Coolsavings,com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (citing Bell Commc’ns Rsch., Inc. v. Vitalink Communications Corp., 55 F.3d 615, 620 (Fed.

“We agree with Patent Owner that the “memory module” includes structure to connect with a “host system” including its memory controller. See, e.g., Ex. 1001, code (57), 12:52–59. The claims do not mention a “memory controller,” but they do mention that the “memory module” has an “interface” to connect with a “host system.” Ex. 1001, 38:20–25 (claim 1), 39:63–65 (claim 16), 41:6–8 (claim 24). That the “memory module” has structure for connecting to the host system’s memory controller may thus be implied from the claims. We agree with Petitioner that the District Court’s determination was that the preambles (presumably of claims 1, 4, 6, 11, 16 and 25) are limiting. Ex. 2032, 35. To the extent that the District Court’s determination construed “memory module” to include structure necessary to connect to a memory controller, our construction of “memory module” is consistent.” slip op. at 17
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“conversion for double-rank DIMMs can be accommodated with a form factor design of approximately about one square inch (both sides of the printed circuit board).” Ex. 1023 ¶ 13. Thus, Harris indicates that the VRM circuitry to generate two regulated voltages can fit within this space. Patent Owner argues that Petitioner’s evidence shows that each ADP1821 converter package would be about 0.193 by 0.236 inches. Sur-Reply 12 (citing Ex. 1078, 20–23). This means three ADP1821 converters would occupy about 40% of the available space. Patent Owner does not demonstrate that the remaining 60% of available space would have been insufficient to accommodate the additional components required for three voltage converters. Id. at 12–13. In any case, we do not view Harris’s disclosure of “approximately about one square inch” to limit the applicability of its teachings to a person of ordinary skill in the art. In the same paragraph, Harris states that the form factor “may be suitably modified.” Ex. 1023 ¶ 13. Patent Owner further argues that “independent voltage sources for different voltages would require specific control circuitry to delay and more precisely control each voltage source’s ramping rate, adding complexity and cost without commensurate benefits.” Sur-Reply 14 (citing Ex. 2061 ¶ 90). However, Dr. Wolfe states that it is simpler to use multiple regulators for multiple voltages since a single regulator that generates multiple voltages is more complicated than multiple regulators. Ex. 2060, 53:16–54:14, 89:1–21, cited in Reply 14. Dr. Wolfe further indicates that buck converters can be in some applications “extremely small.” Ex. 2060, 89:11–15. Dr. Wolfe further testifies that multiple smaller converters may be less costly than a larger single converter because of component costs, separated spaces available for converters on circuit board, and other “ordinary engineering factors.” Id. at 45:21–46:10. Although Patent Owner may be correct that individual control of multiple voltage regulators would have required additional control circuitry, this does not meaningfully undermine the benefits that Petitioner mentions including permitting power sequencing, independent control of voltages, improved efficiency without generating excess heat or requiring cooling devices, and saving power. Pet. 29–30 (citing id. at 14–19; Ex. 1028, 17–20; Ex. 1026, 2–3, 9; Ex. 1028, 30–32; Ex. 1040, 1, 23–24 (Figs. 22–25); Ex. 1041, 1, 13; Ex. 1048, 3; Ex. 1058, 5; Ex. 1059, 5:23–30; Ex. 1062, 11, 13; Ex. 1064 ¶ 101; Ex. 1003 ¶¶ 240, 255). Dr. Wolfe testified that, in at least some circumstances, multiple converters may be less complicated, less costly, and take up less space. Ex. 2060, 45:21–46:10, 89:11–15. Patent Owner’s argument that a single converter generating multiple voltages would be better in some circumstances does not negate that Petitioner’s proposed use of multiple converters for multiple voltages would have been preferred in other circumstances that a person of ordinary skill in the art would have recognized. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (“Our caselaw is clear. It’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.’” quoting PAR Pharm., Inc. v. TWI Pharms., Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)). Thus, Patent Owner’s argument does not undermine Petitioner’s showing of a motivation to combine Harris and the FBDIMM Standards.” slip op. at 25

“not implicitly define the phrase “analyzes the data to determine the patient’s breathing patterns,” as proposed, because Patent Owner has failed to show any sufficient evidence that the ’009 patent clearly expresses an intent to redefine the phrase or define the phrase in terms other than its plain and ordinary meaning. In other words, implied lexicography does not apply here.
