.Oyster Optics, LLC (“Oyster”) is the owner of U.S. Patent No. 7, 6 20,327 (“the ’327 patent”). The ’327 patent is directed to transceiver cards for sending and receiving data over a fiber optic network. In November of 2016, Oyster sued various fiber optic equipment manufacturers in the United States District Court for the Eastern District of Texas for infri ngement of the ’327 patent. Among the defendants were Alcatel

- Lucent USA, Inc. (“ALU”) and Cisco Systems, Inc. (“Cisco”). 1 On September 4, 2018 , addressing the parties’ cross

- motions for summary judgment, the district court granted partial summary judgme nt in favor of ALU and Cisco. The court did so because it found that a settlement agreement between Oyster and Fujitsu Limited (“Fujitsu”) and Fujitsu Network Communications, Inc. (“FNC”) (“the Oyster/Fujitsu Agreement” or “the Agreement”) had the effect of releasing ALU and Cisco from

I.In November of 2016, Oyster sued FNC for infringement of the ’327 patent. In its suit, Oyster alleged that FNC infringed the patent by “ making
, selling , using, offering for sale, and/or causing to be used” versions of Fujitsu’s 100G/400G LN Modulator and 100 G /400G Integrated Coherent Receiver , among other products

. . . exported or imported, made, have had made, used, distributed, offered to sell, sold, or otherwise disposed of Licensed Products or components of Licensed Products.” Id. at 4

. In Section 4.1 of the Agreement, Oyster grants to “FNC, Fujitsu, and their Affiliates” a forward

. Section 1.3 of the Agreement s tates that “LicensedProducts” means “any products, product lines, services, devices, systems, components, hardware, software and/or software algorithm and/or combination of any one or more of the foregoing, made, sold, imported

The “Licensed Products” definition contains two add itional provisions. They are as follows: For clarity, this definition of Licensed Products does not prevent Oyster from exercising its patent rights in instances where its infringement allegations do not include or refer to a Licensed Product. For furt her clarity, this definition of Licensed Products also does not prevent Oyster from exercisingits patent rights in instances where its infringement allegations do include or refer to a Licensed Product, unless the only reasonable and intended Case: 19-1255 Document: 77-2 Page: 5 Filed: 05/08/2020OYSTER OPTICS , LLC v.

A. In the wake of the Oyster/Fujitsu Agreement, ALU and Cisco moved for partial summary judgment in Oyster’s suit against them .

(2) Fujitsu Optical Components (“Fujitsu Optical”) is an “Affiliate,” as defined in the Agreement, of Fujitsu. (3) ALU and Cisco eac h acquired Fujitsu modulators and receivers directly or indirectly from Fujitsu Optical. Thus, ALU and Cisco are customers of Fujitsu in accordance with the release provision of the Agreement. (4) The Fujitsu Case: 19-1255 Document: 77-2 Page: 6 Filed: 05/08/2020OY STER OPTICS , LLC v.

. The court also stated that, based upon two alternate approaches, it was holding that, under the Oyster/Fujitsu Agreement, ALU and Cisco were released from Oyster’s claims of infringement “as to the Fujitsu and its affiliates’ products.” Id. at 72. The court informed the parties that it would issue a writte n opinion explaining its holdings. Id. at 70, 71. On September 4, 2018, the district court issued the Summary Judgment Decision . The court began its analysis by holding that the release of Section 3.1 applies to Fujitsu, Fujitsu Affiliates, including Fuj itsu Optical, and customersof Fujitsu and its affiliates, where the customers have “exported or imported, made, have had made, used, distributed, offered to sell, sold, or otherwise disposed of Licensed Products or components of Licensed Products.” Summa ry Judgment Decision at 8

. The district court stated, “ [i] t is undisputed that [ALU and Cisco] are customers of Fujitsu’s affiliate Fujitsu Optical.” Id. The district court then turned to the question of whether, as customers of Fujitsu Optical, ALU and Cisco were released from liability for infringement by Section 3.1 of the Oyster/Fujitsu Agreement. Id. In its motion s for summary judgment, Oyster argued that A LU’s and Cisco’s products were not released from infringement by the Case: 19-1255 Document: 77-2 Page: 7 Filed: 05/08/2020OYSTER OPTICS , LLC v. ALCATEL

Agreement because , on their own individually, the Fujitsu modulators and receivers contained in the accused products could not satisfy essential claimed features of the ’327 patent and thus did not “substantially embod[y]” the patent claims . Therefore, Oyster maintained , it could exercise its patent right s under the “ [f]or further clarity” provision of Section 1.3

. Id. at 10 ; see also Appellant’ s Br. 13

– 14

. In Defendants’ Summary Judgment Motion on Release , ALU and Cisco argued that Section 3.1 of the Oyster/Fujitsu Agreement released them from liability forinfringement of the ’327 patent for those products that contain ed Fujitsu modulators and receivers that A LU and Cisco purchased from a Fujitsu Affiliate. ALU and Cisco contended that the “[f]or further clarity” provision did not change the scope of the definition of “Licensed Products” set forth in Section 1.3 of the Agreement. Appellees’ Br. 13; s ee genera lly Defendants’ Summary Judgment Motion on Release

. In separate motions, they also argued that Oyster’s patent rights with respect to the accused products under the ’327 patent were exhausted as a result of Fujitsu Optical’s authorized sales of the modula tors and receivers to ALU and Cisco. Appellees’ Br. 13

. As to whether the “[f]or further clarity” provision of Section 1.3 limited the definition of “Licensed Products” in Section 3.1
, t he district court held that the clause only applies to the Agreement’s license provision in Section 4.1, where the term “Licensed Products” appears, and not to the customer release provision in Section 3.1, where the term also appears. Summary Judgment Decision at 9

– 10

. Referring to the “ [f] or further clarity” provision , the court stated: “[I]t means that the law of patent exhaustion is acknowledged by the Parties [to the Agreement] to apply to the Licensed Products identified within the [Agreement]. The provision is a prospective pre servation [] of rights under the forward

- looking license of Section 4.1 alone, but it has no effect as to the retrospective release of Section [3.1].” Id. at 9 (bracketed revisions added). Case: 19-1255 Document: 77-2 Page: 8 Filed: 05/08/2020OY STER OPTICS , LLC v. ALCATEL

Concluding, the district court found that the Fujitsu modulator s and receivers contained in ALU’s and Cisco’s products qualified as “Licensed Products” within the meaning of Section 1.3 for three reasons. First , the modulators and receivers were at least either “products,” “devices,” “components,” and/or “hardware.” Second , the modulators and receivers were “made, sold, imported, or distributed” by an Affiliate (Fujitsu Optical). And
, t hird , the modulators and receivers were “ sold to, distributed to, or otherwise provided (directly or indirectly) to any customer by FNC, Fujitsu Limited, or their Affiliates.” Id. at 10

. The courtthus held that the Fujitsu modulators and receivers qualified as “Licensed Products” within the meaning of Section 1.3 of the Agreement. Id. at 10

– 11

. Having determined that the Fujitsu m odulators and receivers were “Licensed Products,” the district court ruled, “ a ll of Oyster’s claimsbased upon the Licensed Patents against any accused product containing a Licensed Product or components of Licensed Products have been released under the [Oyster/Fujitsu Agreement], specifically including accused products sold prior to May 22, 2018, that include a Fujitsu [modulator] or [r]eceiver.” Id. at 11

– 12

. Accordingly, the court held that ALU and Cisco were released from Oyster’s claims for infring ement of the ’327 patent for those products containing Fujitsu modulators and receivers that were sold prior to the May 22, 2018 effective date of the Agreement

. B. In the second part of its summary judgment decision, the district court concluded that ther e was an alternative ground for concluding that the Oyster/Fu j itsu Agreementreleased ALU and Cisco from liability under the ’327 patent. Id. at 12

. The court determined that, to the extent its holding with respect to the “ [f] or further clarity” provisio n of Section 1.3 was held on appeal to be incorrect, ALU and Cisco still would be released from liability. Specifically, the court found that, in light of Oyster’s contentions Case: 19-1255 Document: 77-2 Page: 9 Filed: 05/08/2020OYSTER OPTICS , LLC v. ALCATEL

- LUCENT USA , INC

. 10

and representations “ in the prior Fujitsu litigation ,” the Fujitsu products ide ntified in that litigation “embody the essential features of the patented invention,” as required by the “ [f] or further clarity” provision of Section 1.3

. Summary Judgment Decision at 12

– 17

. 5 “Therefore,” the court stated, “in the event that the ‘for fur ther clarity’ provision in Section 1.3 of the [Oyster/Fujitsu Agreement] limits thedefinition of Licensed Products, the Court holds that Section 3.1’s release still applies to the Defendants as to any claim of infringement relating to the ’327 Patent wher e theaccused products contain one of the Accused Instrumentalities of the Fujitsu litigation.” Id. at 17

. The parties sought clarification of what products were encompassed by the Summary Judgment Decision . Oyster interpreted “ Accused Instrumentalities of the Fujitsu litigation ” to mean only those specific model numbers named in infringement contentions referenced in the Summary Judgment Decision

. In other words, according to Oyster, under the court’s alternative ruling, in order to be cov e redby the release of Section 1.3 as a “Licensed Product” a Fujitsu modulator or receiver contained in an accused ALU or Cisco product had to have the same model number as a modulator or receiver listed in the infringement contentions Oyster served on FNC in case No. 2:16

and ‘100G/400G Integrated Coherent Receiver’ prod ucts

. ” Further, ALU and Cisco urged that the model numbers were “exemplary.” In its November 7 th Order , the court held that ALU and Cisco’s interpretation of the relevant part of the Summary Judgment Decision was correct. November 7 th Order at 2.

. II. Oyster makes three main arguments on appeal. First, it con tends that the district court erred when it construedthe “[f]or further clarity” provision to not apply to the release of Section 3.1. Appellant’s Br. 20

– 38

. Second , evenif the “[f]or further clarity” provision does not apply to Section 3.1, Oyster urg es , the plain language of that Section does not provide a release for a customer to buy Fujitsu’s components and then incorporate them into an infringing product. Id. at 38

– 40 ; Reply Br. 4

– 11

. Third , Oyster contends that the district court ’s alternative ruling is incorrect because the Fujitsu modulator s and receiver s do not “substantially embody” the claims of the ’327 patent. This is so, Oyster alleges, because the claims of the ’327 patent are directed to a transceiver card and require components in addition to a modulator and a receiver. Appellant’s Br. at 42

– 46. I n the Fujitsu litigation
, Oyster argues, Oyster consistently accused only Fujitsu’s transceiver card and module of direct infringement, not the Fujitsu modulato r s and receiver s , which Oyster states it accused only of indirect infringement

. Id. at 46

– 54. Oyster further argues that the court’s alternative ruling is incorrect because Oyster’s statements in the prior Fujitsu litigation pertained only to specific mo dels of Fujitsu modulators and receivers and “many of ALU’s and Cisco’s products [currently] accused of infringement utilize Fujitsu modulators and/or receiverswith model numbers that do not appear in the lists in Oyster’s contentions [in the prior Fujits u litigation].” Id. at 54

– 57. In addition, Oyster contends the district court erroneously construed Oyster’s statements from the prior Fujitsu Case: 19-1255 Document: 77-2 Page: 12 Filed: 05/08/2020OY STER OPTICS , LLC v. ALCATEL

- LUCENT USA , INC

. 13

litigation to be legally binding judicial admissions. Id. at 50

– 54. In response, Appellees a rgue t hat the dist rict court properly found that the “[f]or further clarity” provision of Section 1.3 does not limit the scope of the term “Licensed Products

. ” Rather, it serves to acknowledge the law of patent exhaustion and clarif ies that Fujitsu’s customers have not been awarded a prospective license. Appellees’ Br. 22

– 23 , 34

– 40

. Appellees contend that Oyster waived its second argument by not raising it before the district court . E ven if we were to consider the argument, Appellees argue , the language of Section 3.1’s release applies to “any and all claims of infringement under any patent right ” and thus
encompass es Appellees’ use of Fujitsu components in their products. Appellees’ Br. 43

– 45. Appellees also urge us to affirm the di strict court’s alternative ruling. Appellees assert that “ [u]ndisputed evidence

— Oyster’s contentions, pleadings, and expert reports in the Fujitsu litigation

— shows that the Fujitsu components in Cisco’s and ALU’s products substantially embody the ’327 pat ent’s claimed invention under the [Agreement].” Appellees’ Br. 26 , 45

– 65

. Oyster and its experts have admitted that the Fujitsu components in this caseperform in materially the same way as the Fujitsu modulators and receivers named in the prior Fujitsu litigation, Appellees state.
For the reasons that follow, we affirm the decision of the district court on the basis of its alternative ruling. We express no view with respect to the court’s primary ruling.
III. As noted, Section 3.1 of the Oyster/Fujits u Agreement provides a release to “ all customers

. . . of FNC, Fujitsu Limited, and their Affiliates, ” with respect to “ Licensed Products or components of Licensed Products.” Section 1.3 of t he Agreement defines “Licensed Products” broadly

. Case: 19-1255 Document: 77-2 Page: 13 Filed: 05/08/2020OYSTER OPTICS , LLC v. ALCATEL

- LUCENT USA , INC

. 14

Then, in the “[f]or further clarity” provision, it states that
, when the “only reasonable and intended use of the component comprising the Licensed Product is to practice theclaim and the component substantially embodies the patented invention by embodying its ess ential features,” Oyster is “prevent[ed] from exercising its patent rights ” under the Agreement. Summary Judgment Decision at 12

– 15

. The question presented by the district court’s alternative ruling is a narrow one. The parties do not dispute that “theonly reasonable and intended use” of the Fujitsu modulators and receivers contained in Appellees’ accused products is to practice the asserted claims of the ’327 patent. Thus,the only issue to be decided is whether the Fujitsu modulators and receivers “s ubstantially embod[y] the patented invention by embodying its essential features.” In addressing this issue at the conclusion of the August 9 hearing, the district court stated: [T] he claims, positions, assertions, contentions, and other positions of [Oy ster] in this litigation are such that they would fall within the language of the

“ for further clarity ” provision, which I think is undisputedly lifted from language addressing the concept of patent exhaustion, such that even if it were a limitation on lic ensed products, in this case, [ALU and Cisco] would be within that limitation based on what [Oyster has] alleged and how [it] ha [s] pursued the litigation in this case heretofore, such that they would meet that limitation and would also be released.

. Thus, the district court reasoned that Oyster’s infringement contentions served to satisfy ALU’s and Cisco’s burden of establishing that the Fujitsu modulators and receivers contained in ALU’s and Cisco’s products substant ially embody the patented inventio n by embodying its essential features. See Vanmoor v. Wal

testimony, not complaint a llegations. That said, in the circumstances of this case, we do not think it was error for thedistrict court to rely on this material, especially infringement contentions, which served to flesh out the infringement allegations in the prior Fujitsu litiga tion. 6 In sum, in the face of its repeated and consistent statements alleging infringement of the ’327 patent by the Fujitsu modulators and receivers themselves , Oyster’s present argument that the modulators and receivers are merely claim components and do not practice the claim or substantially embody the invention of the ’327 patent is not persuasive

. In other words, we do not believe the districtcourt erred when it found, for purposes of the Oyster/Fujitsu Agreement: (i) that the Fujitsu modulators and receivers at issue embody the essential features of the patented invention in view of “what [Oyster] alleged and how [it]

. . . pursued the litigation”; and (ii) that the Fujitsu modulators and receivers thus fall under the release of liability for direct ly infringing devices

Mobile persuasively established that, in view of High Point’s own infringement contentions, the accused [products] substantially embodied every purportedly inventive element of the claimed inventions.”)

. Accordingly, we agree with the district court that the release of Section 3.1 of the Agreement applies to ALU and Cisco as to “any claim of infring ement relating to the ’ 327 patent where t h e accused products contain one of the Accused Instrumentalities of the Fujitsu litigation

. Nor do we find the district court’s ruling in the November 7 th Order clarifying the scope of its alternate ground in the Summary Judgment Decision to be in error. Appelleesprovided evidence that Oyster based its infringement allegations in the Fujitsu litigation on compliance with a standard that encompasses the category of 100G/400G LN Modulator s and 100G/400G Integrated Coherent Receiver s comprising the Fujitsu modulators and receivers contained in Appellees’ accused products
