    “Also, to the extent Masaba relies on extrinsic expert testimony, we note that Masaba’s expert cites absolutely no support for his understanding of the claims, much less explains why we should adopt his understanding over the plain and ordinary meaning of “conveying aggregate” and “moving aggregate.” See Ex. 2004 ¶ 34. Absent supporting citations, such extrinsic testimony is entitled to little, if any, weight. As such, we reject the notion that Waldner’s discharge chute member 242 is not a conveyor “for conveying aggregate” or “for moving aggregate,” as required by claim elements 1[h] and 1[i].” slip op. at 21

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “We disagree that Dr. Durham does not possess the necessary level of skill in the art to qualify as an expert in this case. Looking at the specification of the ’689 patent and the prior art of record, we think Masaba sets the bar too high. We acknowledge that one of ordinary skill in the art should have some education and/or experience in the mechanical art of conveying aggregate materials, but we do not think opining on the ’689 patent and asserted prior art necessarily requires that person to have the amount of education and experience that Masaba advocates. The ’689 patent relates generally to an “aggregate transferring system for receiving aggregate from a vehicle and elevating the aggregate to a higher vertical level for deposit into, for example, a silo.” Ex. 1001, 1:15– 18. And, as described in the ’689 patent and discussed later, the transferring system is an assembly of known types of conveyors, such as a belly-dump truck conveyor, a bucket elevator, and an articulated belt conveyor, for transferring the aggregate horizontally and vertically from a belly-dump truck to the discharge point, such as a silo. Without doubt, Dr. Durham has enough education and experience to reliably opine on the combination of known parts.” slip op. at 8

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction needed

    “We reject this argument for several reasons. First, nowhere does the plain language of the claims specify how the aggregate is conveyed or moved from the conveyor extension assembly’s inlet to its outlet, be it passively by means of gravity or actively by means of a conveyor belt. Instead, the claims simply use those verbs according to their plain and ordinary meaning, which is “to transfer or deliver” or “to cause to go or pass” from one place to another. See Ex. 3001, 253 (defining “convey”), 760 (defining “move”).10 Second, the specification of the ’689 patent similarly uses these terms in a plain and ordinary sense, without ever attributing to them some sort of special meaning. See, e.g., Ex. 1001, 4:9–12 (“The apparatus 10 is suitable for performing the transfer of aggregate from 10 We reference the original pagination of the dictionary in which these definitions appear. one location to another, such as, for example, from a vehicle carrying the aggregate to a silo 1 for storing the aggregate.”). The ’689 patent specification also makes clear that active conveyance of the aggregate is an option and not a requirement of the claimed invention, stating that the conveyor extension assembly “may further include a conveyor belt 150.” Ex. 1001, 10:60–66 (emphasis added). Limiting claim elements 1[h] and 1[i] to a device “for actively conveying” or “for actively moving aggregate” would improperly import limitations from the specification into the claims. Thus, based on the intrinsic evidence, we determine that claim elements 1h and 1k are properly construed to encompass passive and/or active movement of the aggregate via the conveyor extension assembly.” slip op. at 20

See id. at 24–25. Only in disputing Solaris’s Ground 3 does Masaba advocate that the claim term “trailer structure” should be construed under § 112(f), and then only in conjunction with dependent claims 3 and 21. See PO Resp. 58. As such, we address Masaba’s proposed construction in our analysis of Ground 3. We now turn to Solaris’s grounds of unpatentability.” slip op. at 12

    “on embodiments of Yeh with concentric sand screens having nine shunt tubes (six transport tubes and three packing tubes) (Yeh Figures 4A–B) and eccentric sand screens with four shunt tubes (two transport tubes and two packing tubes) (Yeh Figures 8A, 8C). See Pet. 32–37, 39, 41–43. Yet, Petitioner’s reasoning as to why “a higher-pressure shunt tube assembly necessitated greater wall thickness” rests on an unspoken one to one comparison between the shunt tubes of the different systems. See id.; see also Ex. 1003 ¶¶ 291–297 (Petitioner’s declarant comparing possible transport tubes of different pressure regions without considering or addressing any difference in the number of transport tubes). However, the embodiments relied on by Petitioner have different numbers of shunt tubes, and thus the greater wall thickness does not appear to be “necessitated” in the way inferred by Petitioner. Further, Petitioner’s analysis would seem to be most appropriate when comparing two concentric sand screens for different pressure regions, or two eccentric sand screens for different pressure regions. relies on Yeh’s teachings related to a horizontal well bore of 5000 feet for the “concentric screen → crossover tool → eccentric screen” arrangement, as well as, for why the concentric screen needs to be rated for a high pressure. Pet. 32–37, 39, 41–43. Petitioner also refers to these features for why one of skill in the art would combine the teachings of Yeh and Yeh2. Id. at 32. However, on cross-examination, Petitioner’s declarant agreed that it is concentric sand screens having a 6x3 shunt tube design that would provide the noted benefits of being rated for a higher pressure and being more robust (as relied on in the Petition), as compared to eccentric sand screens. Ex. 2013, 42:20–43:8; Sur-reply 4–5. This also exposes another issue with Petitioner’s arguments. Though Petitioner identifies that one of skill in the art would be aware that material choice, wall thickness, and pipe diameter all impact burst pressure of a pipe (Pet. 42 (citing Ex. 1017, 24 (Equation (14))), the Petition essentially ignores the fact that the claims do not require a single pipe in isolation. The claims require two shunt tube assemblies, each surrounding a base pipe within a wellbore. It is uncontested that a wellbore provides a confined space for such a system and thus any change in wall thickness of one pipe can result in a significant impact in the function of the other pipes. We find the testimony of Petitioner’s declarant (see, e.g., Ex. 1003 ¶¶ 290–297) unpersuasive when discussing wall thickness because it focusses on basic considerations of a standalone pipe, without sufficient consideration of the claimed completion assembly with its required pipe and tube structure.

    “Thus, we agree with Petitioner that the combination of Yeh and Yeh2 teaches determining the shunt tube system operating pressures associated with the distal end of the production zone, but also more generally, determining the operating pressures along the entire production zone. With this knowledge of the system operating pressures, Petitioner argues that one of skill in the art would have selected eccentric screens for the distal end of the production zone “at any point at which the slurry pressure dropped below the pressure capacity of the eccentric screen shunt tubes.” Pet. 66 (citing Ex. 1005, 30:16–20; Ex. 1003 ¶ 388). In other words, knowing that the pressure decreases as you approach the toe, Yeh’s low-pressure rated eccentric screens could be used from some point prior to and covering the toe. determined pressure.” PO Resp. 37–38.

We find convincing Petitioner’s argument that one of skill with this understanding of the system pressures would select a shunt tube system rated to not only address the distal end, but also to address the needs of the adjacent region, so long as the pressure rating supported such a selection.

Patent Owner also relies on dependent claim 2, which depends from independent claim 1. PO Resp. 28–29. Dependent claim 2 adds to claim 1 the requirement that the driver be configured to increase and decrease the transmission frequency when a particular signal is received. See Ex. 1001, 28:47–54. Patent Owner asserts that this means that the driver is configured to increase/decrease the “substantially different” frequency, namely a frequency that lies within the near-linear region of a frequency-amplitude graph, and argues that, “[i]n reading claim 2 as a whole, a POSITA would understand that the ’696 Patent is directed to a linear control technique for predictably regulating power transfer.” PO Resp. 28–29 (citing Ex. 2006 ¶ 101).

Reply 17. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . .

Petitioner’s proposed combination is the application, to Onishi’s charging system, of Flowerdew’s general teaching of the technique of using an alignment mechanism in order to optimize the alignment of the inductive coils and to maximize the inductive coupling. See, e.g., Pet. 15 (“[A] POSITA would have been motivated to implement Onishi in a manner that includes an alignment mechanism as suggested by Flowerdew (e.g., a dished recess or other shaped surface feature, a directional logo/marker, or both) so that the primary and secondary coils would be more readily ‘optimized’ for alignment and the inductive ‘coupling is maximized.’”). Flowerdew teaches, for example, that, with the use of a dished charging surface, the secondary unit “tends to align in one axis” and “[t]his alignment is such that the coupling between a solenoid receive coil in secondary unit 304 and the charging coils of charger 302 is maximized.” Ex. 1005, 11:25–52.

To the extent Patent Owner’s proposed construction specifies elements to be excluded, we find no support for these exclusions, and in fact, find opposite language in the specification of the ’384 patent: while Patent Owner proposes that a detail view must not include “information that is associated with a series,” the specification describes a detail view as provided in the case where “a series with only a single episode” has been selected.

As discussed, the claims recite that a detail view is provided “if [a] selection . . . is for one of a movie or single show” and that the detail view “presents information about a selected item of the VOD content” and a that a digest view is provided “if the selection in the collection view is for a series” and that digest view “provides a listing of two or more episodes associated with a series.” See, e.g., Ex. 1001, 57:23–27, 57:31–37. Thus, by the language of the claims themselves, the provision of “either a detail view or a digest view” relates to the received third selection and is based on what that selection was. The “either . . . or” in the claim thus relates directly to the third selection and not to the resulting views. This is consistent with Dr. Surati’s testimony. See Ex. 2002 ¶ 67 (The claims “present[] the third selection as a binary choice: either the third selection is a series (in which case the digest view is presented), or the third selection is a movie or single show (in which case the detail view is presented).” While Patent Owner insists that the language and logic of the claim “excludes providing a view that can be both a detail view and a digest view,” (PO Resp. 21) we determine that this proposed negative limitation finds no support through the Therefore, we decline to adopt the proposed claim construction that further limits the plain language of the claims.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “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. In claim 1, a biological sample from the patient must be tested to determine if the cancer is MSI-H and, if so, the patient is treated with a therapeutically effective amount of pembrolizumab. For this reason, if the prior art teaches the limitations of 1) testing a biological sample obtained from a patient having cancer to determine that the patient’s cancer is microsatellite instability high or mismatch repair deficient, and 2) treating the patient with a therapeutically effective amount of pembrolizumab if the patient’s cancer is determined to be microsatellite instability high or DNA mismatch repair deficient, the art anticipates claim 1.

Contrary to Patent Owner’s argument that it could not file a patent application without results from the MSI-H clinical study, we note that the inventors filed a provisional patent application on November 13, 2014, which, although also filed more than a year after the publication of the MSI-H clinical study, disclosed no clinical results or data.

PO Resp. 11–14. We are not persuaded that either the size of the genus in the MSI Study Record or whether one of ordinary skill in the art would have been able to envisage every species within it is dispositive of whether the MSI Study Record anticipates claim 1, where one of ordinary skill in the art would have known that specific cancers recited in claim 1 would be included in the MSI Study Record.

Claim 1 does not require that the patient have each and every one of the sixteen listed cancers to anticipate the claim.

Similarly, during his deposition, Dr. Goldberg also agreed that endometrial, gastric, and small-bowel cancers would come to mind when he saw a reference to MSI-high non-colorectal cancer.
