“understanding that the claim term “from bottom to top” refers to the vertical arrangement of word lines in the memory portions from bottom to top and not from source end to drain end, as asserted by Petitioner. Inst. Dec. 17. In other words, the claim terms describing the first and second portions having word lines “from top to bottom” refer to the relative vertical location of the word lines within the memory portions and not to location of the word lines relative to the source or drain. Our construction is based on the plain and ordinary meaning of the express language of the independent claims, which states that the second memory portion is formed either above or below the first memory portion. The forming of one memory portion above or below another portion establishes a top and bottom in relation to those portions. For example, claim 5 is directed to a “program method of memory” that requires a second portion formed above the first portion. A second memory portion that is formed above a first memory portion is on top relative to the first portion. Similarly, claims 1 and 1 and 11, which recite a memory having a second portion formed below a first portion, establish that the second portion is on the bottom relative to the first portion. Thus, the claim language itself establishes the vertical locations of the memory portions relative to each other (e.g., a second memory portion that is above the first portion is on top, relative to the first portion). It follows that claim terms referring to the top and bottom of word lines within the memory portions also refer to relative vertical locations of the word lines within the memory portions.

“Here, in our opinion, Patent Owner has shown that the Specification describes the potential destinations of a vehicle as limited to physically fixed, non-transient objects or features. PO Resp. 18–21. As an initial matter the ’805 patent is titled “Docking Assistant” and explains its purpose for guiding a “vehicle to a stop at a specific location.” Ex. 1001, codes (53), (57), Abstract. We acknowledge that claim 1 does not expressly recite that “at least one potential destination” is a fixed destination or location. See id. at 7:61– 63 (Claim 1 requiring “extracting from the acquired image data positional parameters of at least one potential destination relative to the motor vehicle;”). Yet, in the context of the relatively brief specification, there is no explanation, example, or embodiment which reasonably extends the meaning of “destination” or “potential destination” beyond a fixed location. The ’805 patent describes in the Abstract that [m]any day-to-day driving situations require that an operator of a motor vehicle guide the motor vehicle along a specific course and bring the vehicle to a stop at a specific location, for example in a parking bay or at a loading platform. Id. at code (57) Abstract. The Abstract explains in the next sentence that “[t]o assist a vehicle operator in such situations, a method and a suitable device for implementing this method, include detecting the potential target objects in the image data of an image sensor and identifying the potential target objects as potential destinations in a multi-stage exclusionary method.” Id. (emphasis added). Nowhere in this initial description of the invention, nor anywhere else that Petitioner points to, is there is expansion of the “specific location” or “potential destination” beyond a docking station or parking bay. Of course, the claim is not limited to these examples, as it would be inappropriate to read in such limitations from the Specification. See Acceleration Bay, LLC v. Activision Blizzard Inc., 908 F.3d 765, 771 (Fed. Cir. 2018) (“Acceleration again attempts to import structural limitations into claims lacking those limitations. . . .

“Patent Owner’s declarant, Dr. Majumder, testifies to the contrary that “[r]ead as an engineer, the ‘805 patent’s present invention is framed around guiding a vehicle to fixed, physical destinations (exemplified by docking stations and similar structures) without fiducials or special markings.” Ex. 2010 ¶ 81. Considering Broggi, Dr. Majumder testifies further that “[a] moving object, such as a preceding car, is not a valid destination under the ‘805 Patent, because it is not a stationary location at which the host vehicle can be guided to stop. To treat such a vehicle as a ‘potential destination’ would lead to collision, not guidance.” Id. ¶ 86. As discussed in our claim construction, given a plain reading of claim 1 in light of the Specification, our understanding of the ’805 patent is consistent with Dr. Majumder’s testimony. We agree that Broggi is directed expressly to the platooning of moving vehicles, and not physically fixed destinations as the proper claim construction requires. Because Broggi does not disclose the use of physically fixed “potential destinations” as required, e.g., in limitations [1.2]–[1.3], and neither Huttenlocher nor Brady are relied upon to overcome this deficiency, Petitioner has not met its burden of persuasion to show by a preponderance of the evidence that claim 1 would have been obvious over Broggi in view of Huttenlocher and Brady.” slip op. at 27

Kim’s Figures 17A–22B do not further address the underlying staircase structure that was detailed in the descriptions of the Figures 4–15 embodiments. Thus, it would similarly be a “reasonable inference” that aspects of the stack structure would be understood to apply to the same stack in the embodiments of Figures 17A–22B, which rely upon, in unaltered form, the earlier-described elements of the stack. stack on bottom, they “replace” and “exclude” any prior description of a gate-stack-on-top.

However, as admitted by Patent Owner, all of Kim’s Figures show only a gate-stack-on-bottom structure. Tr. 41:6–7 (“For the first embodiment, it is true that figures show the gate stack on bottom.”). The fact that Kim’s Figures 17A–22B, which add etch-stop and barrier layers to the gate stack, are shown only as gate stack on bottom is merely consistent with the uniform use of gate-stack-on-bottom in Kim’s Figures, which show the layer-by-layer construction of its device. Like Figures 4–15, Figures 17A–22B exemplify rather than limit the description of the previously described memory stack, and do not exclude the gate-stack-onbottom description of the memory stack. Kim can be used for all it realistically teaches, including descriptions in its disclosure that are not represented by specific Figures. See In re Chapman, 357 F.2d 418, 424 (C.C.P.A. 1966) (stating that a reference “is not limited to the disclosures in its specific illustrative examples.”).

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
