I. INTRODUCTION

This case involves claims of patent infringement between Comcast Cable Communications, LLC, and Sprint Communications Company, LP. After withdrawal of several claims of infringement, only Com-cast’s claim for infringement of its U.S. Patent Number 6,885,870 (“the ’870 patent”) against Sprint and Sprint’s Counterclaims for infringement of its U.S. Patents Numbers 6,754,907 and 6,757,907 (“the ’907 patents”) against Comcast remained in the case. The Court granted summary judgment in favor of Comcast as to Sprint’s counterclaims under the ’907 patents by Memorandum and Order dated August 24, 2016. See Comcast Cable Commc’ns, LLC v. Sprint Commc’ns Co., LP (Comcast v. Sprint II), 203 F.Supp.3d 499 (E.D. Pa. 2016). That Memorandum contains the factual background, procedural history, and details of the underlying patents in this case. For purposes of this Memorandum, the following summary of the invention will suffice, and additional facts will be incorporated as necessary.

The ’870 patent, titled “Transferring of a Message,” claims a method “for inquiring about information relating to a [wireless] terminal of a cellular network from the cellular network, from a messaging server external to the cellular network.” ’870 patent,- at 2:45-48. The preferred embodiment of the invention can be summarized as follows:

[125]*1251. A multimedia messaging service center (“MMSC”) receives and stores a multimedia message (“MMS”). ’870 patent, at 6:14-16. The MMS may contain pictures, text, or video, and is addressed to an RFC822 (i.e., e-mail) address, in the standard form name@domain.; ’870 patent, at 6:47-61. Alternatively, the message may be addressed to a phone number, which is then converted by the MMSC to a corresponding e-mail address. ’870 patent, at 6:62-64. In the preferred embodiment, the MMSC is located outside the General Packet Radio Service (“GPRS”) system of the Global System for Communications (“GSM.”). ’870 patent, at 6:65-66.
2. The MMSC maps the RFC822 address to a different address called an MMS-ID, which the patent describes as an identifier that is “external” to the cellular network. ’870 patent, at 7:10-22.
3. The MMSC sends an inquiry into the GPRS to a server called the Gateway GPRS Support Node (“GGSN”) “to determine the readiness of the wireless terminal to receive data.” ’870 patent, at 8:9-12.
4. The GGSN maps the MMS-ID to a corresponding international mobile subscriber identity (“IMSI”) that is specific to a subscriber identity module (“SIM”) card in the wireless terminal. ’870 patent, at 8:22-25. The GGSN performs the mapping by “inquiring about the IMSI ... that corresponds to [the] MMS-ID from [a] database, in which the correspondences between the MMS-ID and the IMSI code of the wireless terminal are stored.” ’870 patent, at 8:25-29.
5. The GGSN uses the IMSI to search its database to determine if the wireless terminal is currently connected to it. ’870 patent, at 8:31-35. If so, the GGSN (1) retrieves from the database the current dynamic network address of the wireless terminal, and (2) determines whether the wireless terminal is ready to receive the multimedia message. ’870 patent, at 8:35-39. If the desired wireless terminal is not connected to the GGSN, the GGSN inquires -of another GPRS element, the home location register (“HLR”), for the identity of the GGSN to which the wireless terminal is connected, if any, and requests the information from that GGSN. ’870 patent, at 8:66-9:6, 9:47-51.
6. The ultimate result of the process, regardless of the result of step 5, is that the GGSN sends a response message to the MMSC consisting of the information retrieved regarding the wireless terminal — viz. the status of the wireless terminal including its dynamic network address and current GGSN— and .preferably including the MMS-ID, the external identifier used in the request. ’870 patent, at 10:14-28.
7. The MMSC then sends the message to the wireless terminal at its dynamically assigned network .address through the cellular network in packet-switched mode. ’870 patent, at 11:7-10.

Comcast v. Sprint II, 203 F.Supp.3d at 510-11.

Comcast asserted Claims 1, 7, and 113 of the ’870 patent against Sprint. For purposes of the present Motions, only the limitations of Claim 113 are relevant, Claim 113 depends on Claim 112 — i.e., Claim 113 incorporates by reference all of Claim 112’s limitations, and adds additional restrictions. Claim 112, which was not asserted, claims:

A method for inquiring about information relating to a wireless terminal of a cellular network, from the cellular network by a messaging server .external to the cellular network, wherein the method comprises:
[1] sending an inquiry from the messaging server to the cellular network to determine said informa[126]*126tion relating to the terminal, the inquiry comprising a first identifier identifying said terminal, the , first identifier being a specific identifier external to the cellular network;
[2] mapping said first identifier to a specific second identifier in the cellular network, the second identifier being an internal identifier of the cellular network, wherein the mapping is not performed by a Home Location Register;
[3] determining said information relating to the terminal with the aid of said second identifier;
