“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.

“limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20. We are persuaded by the testimony of Dr. Zeglis, Petitioner’s declarant, that compounds weighing over 1500 Da may share those same behaviors, along with certain identified B moieties disclosed as embodiments.

“Based on the full record, we maintain that it is unnecessary to explicitly construe “athletic positioning” because its meaning is already captured in the claim through the recitation of the relationship between the various slopes of the sole that provide “athletic positioning” of the foot. See Ex. 1001, 44:2–14. The recitations of a “first slope,” “second slope,” “third slope,” and “reference slope” translate into the relative heights proposed in adopt Patent Owner’s proposed construction because it incorporates the specification’s consistent descriptions of “athletic positioning” in terms of relative heights and slopes. For example, one embodiment of an “athletic positioning shape” is where “the heel platform may be 10 to 30 mm higher” than “the toe cup and/or the ball of foot cup.” [Ex. 1001], 13:38–45. Another embodiment discloses “an athletic positioning sole that includes an overall geometric shape” including “the heel of the sole [at] a particular height (e.g., h1, which may be 1’s to 10’s of mm) that slopes at an angle (e.g., Ø1) to the toe on the inside edge of the sole” which “may have a height of zero to a few millimeters.” Id., 17:54–62. PO Resp. 29. However, we find Patent Owner’s contention regarding particular heights and specific angles attempts to import limitations from the Specification into claims. Superguide Corp. v.

Other than asserting that “the requisite nexus exists here” (PO Resp. 71), and citing to the Declaration testimony of Mr. Markison (id.

To the extent Patent Owner references Mr. Markison’s testimony, Mr. Markison’s testimony consists solely of the statement that Patent Owner “sells and markets golf and baseball shoes that embody the claims of the ’786 patent” with reference to an exhibit from district court litigation. See Ex. 2008 ¶ 322 (citing Ex. 2014). We find Patent Owner’s reliance on Mr. Markison’s testimony to be insufficient to establish a rebuttable presumption of nexus.

Nonetheless, Athalonz contends that we should adopt its proposed construction because it incorporates the specification’s consistent descriptions of “athletic positioning” in terms of relative heights and slopes.

“Pet. Reply 6–10. In support, we credit the declaration testimony of Under Armour’s expert that one of ordinary skill in the art “would understand that the shape and orientation of the sole (i.e., the platform on which an athlete stands) in relation to the ground is what determines if the foot is placed in an athletic position when in use” and that “[c]leats serve to provide traction, not athletic positioning.” Id. at 8 (citing Ex. 1022 ¶ 15). We also agree with Under Armour’s expert that one of ordinary skill in the art “would [] understand that because the cleats’ height does not contribute to the athletic positioning shape when in use on soft ground (the surface on which golf is played), it would not be included in the measurement of the claimed first, second, and third heights.” Id. at 8–9 (citing Ex. 1022 ¶ 16). We find the testimony of Under Armour’s expert to be credible and supported by the trial record. For instance, the ’291 patent specification itself distinguishes between the “sole” and “cleats” of the shoe as separate components. Ex. 1001, 1:59–61. Similarly, Kim describes the sole and cleats as distinct components of a shoe, illustrating the industry’s understanding of these terms. Ex. 1022 ¶ 14; see also Ex. 1005 ¶¶ 9, 14, 15, 30, claim 1 (describing that the spikes, in Kim, “protrude” or “extend” from the “outsole” and are located below the outsole’s “lower surface.”). We also note that Athalonz’s inclusion of the height of Kim’s cleats in measuring the claimed “heights” appears to be inconsistent with its own litigation position in the parallel district court action. See Pet. Reply 9–10. In particular, as Under Armour notes, “Athalonz did not include the height of the cleats in the measurement of the claimed heights” in accusing Under Armour’s shoes that have cleats of infringement. Id. (citing Ex. 1025, 51, 55–56, 61–62 (Athalonz’s infringement contentions regarding claim limitations [1.6] and [1.9])). To the extent Athalonz asserts that its “infringement contentions are extrinsic evidence that should be afforded little weight” (PO Sur-Reply 12), we disagree. While Athalonz’s infringement contentions may indeed be extrinsic evidence, we nevertheless find they provide an indication of Athalonz’s understanding and application of the claims. As such, we find that Athalonz’s infringement contentions, together with the plain language of the claims, the specification, and the credible testimony of Under Armour’s expert, fully supports Under Armour’s assertion that one of ordinary skill in the art in the relevant time frame “would understand that the claimed first, second, and third heights would be measured with respect to the bottom of the sole, not with respect to the bottom of the cleats.” Pet.

“We are persuaded by Patent Owner that the term “automatically” in “to automatically disengage the first and second catch structures” means that it is not just the force applied by the user that disengages the first and second catch structures, but also the bias of the mouthpiece that helps to disengage the first and second catch structures. In the first instance, we agree with Patent Owner that the claim itself recites that, upon actuation, the mouthpiece assembly is “release[d]” to “move via its bias from the stowed configuration to the dispensing configuration.” See Ex. 1001, 21:59–64. This meaning is supported by the Specification which states: “In some examples, the mouthpiece assembly is biased toward the dispensing configuration and thus moves automatically under its bias upon release by the user-release mechanism.” Ex. 1001, 1:64–67. We further agree with Patent Owner that the plain and ordinary meaning of “automatic” is that the user operation alone is not responsible for the action. For example, in one dictionary cited by Petitioner, “automatic” is defined as “2: having a self-acting or self-regulating mechanism.” See Ex. 2007, 1.11 The district court construction is consistent therewith. The district court identified two functions, the first of which is the same as that of the ’028 patent, i.e., “Automatically disengaging the first and second catch structures upon actuation of the user release mechanism and thereby releasing the mouthpiece assembly to move via its bias from the stowed configuration to the dispensing configuration.” See Section II.C.1, supra. In discussing that function, the district court states: “While a user may impart force upon user engagement portion 260 to release the mouthpiece, the bias of the mouthpiece towards the dispensing configuration causes the mouthpiece to move automatically, satisfying the requirements of Claim 1.” Ex. 2002, 16.

“Here, it is undisputed that Skechers was neither a party to the earlier lululemon IPR nor had ever before challenged the claims of the ’484 patent. Instead, in an attempt to demonstrate a significant relationship between Skechers and lululemon that might justify application of the General Plastic framework, Nike’s sole argument is that “Skechers created a relationship with lululemon by openly admitting that it used lululemon’s petition as a roadmap” and that “[t]his admitted roadmapping creates an implicit relationship between Skechers and lululemon.” PO Sur-Reply 2. We reject the notion that “roadmapping” alone creates a significant relationship. As noted in Videndum, a second petitioner’s reliance on a first petitioner’s earlier-filed petition, “even ‘as a menu or road map,’ is not sufficient to create a significant relationship that favors denial under the first General Plastic factor.” Videndum, at *2 (emphasis added); see also Ford, at *2 (rejecting patent owner’s argument that Ford’s use of prior Volkswagen and Dell IPRs “as a roadmap for its Petition” was sufficient to create “an ‘implicit’ relationship”). In other words, absent some evidence of a non-mandated7 collaboration between Skechers and lululemon (such as proof of a licensing or other technology-sharing agreement regarding the accused product), Skechers’ use of arguments and evidence similar to those in the earlier lululemon IPR does not create a significant relationship. Nor does it appear that Nike could reasonably establish such a relationship given that Skechers is a direct competitor of lululemon, was sued on an entirely different product than lululemon, and was not sued until after lululemon had already sought inter partes review of the challenged patent.

“In particular, the Board has already performed a detailed analysis of the ’484 patent, including construing the claim terms and applying two of the prior art references—Dua and Hong—that form the primary ground here. As such, the Board is much further along in understanding the challenged claims and the parties’ dispute over their validity than the district court in the parallel litigation. And even if the Final Decision in the lululemon IPR is reversed or remanded on appeal, the Board’s considerable experience with the relevant issues remains. Thus, the fact that the Board has already expended considerable time and resources in deciding the validity of the challenged claims, whereas the district court has not, weighs heavily in favor of institution.10 Indeed, in staying the parallel litigation, the district court expressly recognized the lack of any significant investment by the parties or the court— - “[D]iscovery is still in the early stages.” - “The parties . . . have not yet taken any depositions, any third party discovery, or any expert discovery. . . .

Neither party directs us to evidence of the level of skill in the art beyond what we considered for institution of trial. In the Decision to institute trial, we determined that the level of skill in the art relevant to the claims of the ’393 patent is not limited to knowledge of and experience with conducting research relating to oncology or developing and conducting clinical trials.

We determined that the level of skill also includes knowledge of and experience with treating colorectal cancer patients with immunotherapy compounds, identifying the conditions these patients may have, and understanding the literature regarding clinical trials for such colorectal cancers and the associated conditions and immunotherapy.

“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. We further agree that this relationship is different than the use of the term “after” in claims 7, 20, and 27, wherein patients must be treated with a different cancer therapy, and wherein the cancer must have later progressed for the treatment to be within the scope of these claims. (Ex. 1001, 25:66–7, 26:44–46, 26:63–64.) 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 colorectal cancer to determine that the patient’s colorectal 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 colorectal cancer is determined to be microsatellite instability high or DNA mismatch repair deficient, the art anticipates claim 1.

“For purposes of this decision on institution, we adopt the proffered dictionary definition of “mouthpiece” as “a part (as of an instrument) that goes in the mouth or to which the mouth is applied” (see Ex. 2005), and we construe this as an intended use of this component of the apparatus, because this definition is consistent with the plain and ordinary meaning of the term which is a compound of “mouth” and “piece” and also because this definition is consistent with the Specification. For example, the Specification describes the use of the mouthpiece as follows: “In use, the mouthpiece is adapted to be configured to the dispensing configuration by a user placing the mouthpiece in the user’s mouth and biting upon or otherwise compressing the appropriate portions of sidewalls 92 of the mouthpiece.” Ex. 1001, 8:45–49. We note that, although the Specification refers to bite-actuation of the mouthpiece, for example in the field of the disclosure and certain embodiments (e.g., Ex. 1001, 1:25–27), the independent claims do not require bite-actuation. The Specification identifies the mouthpiece as item 72 (which is depicted, for example, in Figure 25, reproduced supra).
