Before O’MALLEY, WALLACH, and TARANTO, Circuit Judges. TARANTO, Circuit Judge. SIMO Holdings Inc. owns U.S. Patent No. 9,736,689, which describes apparatuses and methods that allow indi- viduals to reduce roaming charges on cellular networks when traveling outside their home territory. SIMO sued Hong Kong uCloudlink Network Technology Limited and uCloudlink (America), Ltd. (collectively, uCloudlink) for in- fringement, alleging that four uCloudlink products came within claim 8 of the ’689 patent (as well as dependent claims that present no separate issues on appeal). In cross- motions for summary judgment of infringement, the par- ties briefed whether claim 8 requires a “non-local calls da- tabase” and, if so, whether the accused products had such a database. The district court granted summary judgment to SIMO that uCloudlink was infringing (and denied uCloudlink’s motion for summary judgment of noninfringe- ment), concluding that claim 8 does not require such a da- tabase. The case went to trial, which, after post-trial proceedings, resulted in a final judgment of $8,230,654 for SIMO. We reverse. We reject the district court’s claim con- struction and hold that claim 8 requires two or more non- local calls databases. We also conclude that, in responding to uCloudlink’s summary-judgment motion, SIMO did not identify a triable issue on the factual question of whether, as uCloudlink asserted, the accused products lack a non- local calls database. We therefore hold that uCloudlink is entitled to summary judgment of noninfringement. Case: 19-2411 Document: 83 Page: 3 Filed: 01/05/2021

SIMO HOLDINGS INC. v. HONG KONG UCLOUDLINK NETWORK 3

I A The ’689 patent deals with roaming charges on cellular networks. The patent describes a scenario in which an in- dividual has a cellphone “with a wireless contract with” cel- lular-service provider “AT&T® in San Francisco” and, when in “London,” uses the cellphone to “make[] a tele- phone call from a VODAPHONE® cellular telephone net- work in London.” ’689 patent, col. 5, lines 1–6. If the user lacks a cellular-service contract with Vodaphone, the user is likely to incur a “high roaming” fee (charged by Vo- daphone to home-network provider AT&T and passed to the user). Id., col. 5, lines 6–8. The patent notes that one way the user can avoid the roaming charges involves replacing a physical component of the phone—specifically, replacing the subscriber identity module (SIM) card inside the phone that identifies the phone to an in-reach cellular network. The user can re- place the home-network SIM card (an AT&T SIM card, in the above scenario) with a SIM card used for a “local” call on a cellular network in the user’s present location (a Vo- daphone card in London). Id., col. 2, lines 46–51. Accord- ing to the patent, however, “[p]urchasing and swapping-out SIM cards is inconvenient, inefficient, and technically chal- lenging for most subscribers, especially when traveling to multiple foreign countries.” Id., col. 2, lines 51–54. To avoid those difficulties, the ’689 patent proposes a differ- ent, electronic technique, not involving the swapping out of a SIM card, to have a present-location cellular provider with which the traveling user has no service agreement (Vodaphone, in London) treat the user’s cellphone as a local device as if it had such an agreement, rather than as a “for- eign” device. Id., col. 6, lines 56–59 (“By ‘foreign’ it is meant that the wireless communication client 106 (or its SIM card) is not subscribed to the wireless communications net- work 102.”). Case: 19-2411 Document: 83 Page: 4 Filed: 01/05/2021

Among other things, the ’689 patent describes a “wire- less communication client” and a “remote administration system.” Id., col. 3, lines 25–50. The client “stores at least a portion of authentication data 530 either on a SIM card and/or in memory 512 as authentication information 532.” Id., col. 14, lines 21–25. The remote administration system “authenticates” devices, “maintains subscriber accounts,” “facilitates the rerouting of non-local calls to further pro- vide reduced cost routing,” and includes an authentication bank of a “plurality of physical identification modules (e.g., SIM cards).” Id., col. 7, lines 1–11; col. 10, line 65, through col. 11, line 2. SIMs generally “store network specific in- formation used to authenticate and identify subscribers on the network.” Id., col. 11, lines 39–40. The SIMs in the authentication bank have the information needed for the wireless communication client to become authenticated (recognized as a local device) by a present-location (local) cellular network. See, e.g., id., col. 11, line 39, through col. 12, line 4. Thus, in one embodiment, a wireless communication client uses authentication data already on a SIM card or stored in the client’s memory to connect to a local cellular network, which connects the client to the remote admin- istration system for the purpose of retrieving information that will enable the client thereafter to become authenti- cated as a local device by a local network (not necessarily the same local network). Id., col. 17, line 36, through col. 18, line 14. Specifically, the remote administration system, after being connected with the client through the initial lo- cal-network connection, verifies the identity of the client and sends it a remote authentication module with SIM in- formation from the authentication bank. Id. The client then uses the new SIM to become authenticated with a pre- sent-location cellular network on which the client works as a local device so that the user avoids further roaming charges.

SIMO HOLDINGS INC. v. HONG KONG UCLOUDLINK NETWORK 5

Some embodiments, of particular relevance on appeal, have an additional feature—a “non-local calls database” in the wireless communication client that helps “greatly re- duc[e] the cost of [some] call[s].” Id., col. 16, lines 5–6; fig. 5A. The specification describes how. “The non-local calls database 525 lists various locations, corresponding area codes, and corresponding local dial-in telephone numbers for use when the subscriber wants to make a non-local call when present at a particular location.” Id., col. 15, lines 57–61. “For example, when a user desires to make a non- local call when within a particular location (e.g., a visiting caller in London wants to call his home office in San Fran- cisco), the client 106 . . . is able to determine that the called number is not within the local area, and then dial a local communication server 128 (FIG. 1) at a local number from the list.” Id., col. 15, lines 61–67.
