MEMORANDUM OPINION
THYNGE, United States Magistrate Judge.
I. Introduction
United States Patent No. 6,282,406 ("the '406 patent"), entitled "Paging Method and Apparatus," is owned by GPNE Corp. ("GPNE"). On February 2, 2007, Time Warner Cable, Inc. ("TWC") filed suit in Delaware seeking a declaration that the '406 patent is invalid, that TWC has not infringed upon the '406 patent, and to issue an injunction against GPNE from charging infringement or instituting any legal action for infringement of the '406 patent.[1] Presently under consideration is GPNE's motion to dismiss, stay, or transfer this case to the Eastern District of Texas.[2]
II. Procedural History
On January 31, 2007, GPNE filed a patent infringement case ("the Texas litigation") in the Eastern District of Texas against Time Warner, Inc. ("TWI"), Comcast Cable Communications LLC ("Comcast"), and Charter Communications, Inc. ("Charter") alleging infringement of the '406 patent.[3] The Texas litigation did not originally include TWC as a defendant, but instead listed TWI.[4] Two days later, on February 2, 2007, TWC filed the present action in this court for a declaratory judgment of noninfringement and invalidity of the '406 patent.[5] In the Delaware complaint, TWC alleges that GPNE intends to include it as a defendant in the Texas litigation and in so doing would impact its business activities.[6] TWC maintains that it was not originally a defendant in the Texas litigation because TWI and TWC are separate entities.[7]
On February 26, 2007, GPNE amended its complaint in the Texas litigation to add TWC as a defendant.[8] That same day, GPNE filed a motion to dismiss, stay, or transfer the Delaware case to the Eastern District of Texas, because the Texas case was the first action that involved the '406 *586 patent.[9] Accordingly, GPNE notes that since the Texas litigation is moving forward against all three defendants, this court should dismiss, stay, or transfer the matter to Texas in the interests of justice and judicial economy.[10]
Jurisdiction is proper in both the Eastern District of Texas and Delaware. The Eastern District of Texas has personal jurisdiction over the defendants, including TWC, as each defendant in the Texas litigation operates a high speed internet system in that jurisdiction, which is the basis of the alleged infringement.[11] Delaware has personal jurisdiction to hear this matter, as all parties involved are incorporated in Delaware. All parties in both matters are large national corporations and none have their principal place of business in Texas or Delaware.[12]
III. Positions of the Parties
Motion to Dismiss or Stay
In the motion under consideration, GPNE asserts that the first-to-me rule is applicable, which favors its first-filed action in Texas. GPNE maintains that the Delaware case should be dismissed or stayed in the interest of national uniformity in patent matters.[13] Because this matter is presently before two different federal courts of equal standing, GPNE contends that consolidation serves the interest of justice.[14] According to GPNE, the first-to-file rule hinges upon which court first obtains possession of the subject of the dispute, and not whether all parties have been identified or added to a case.[15] Furthermore, GPNE argues that even if the parties are not identical, dismissal is warranted if the cases substantially overlap on substantive issues.[16] Thus, GPNE argues that since the Texas litigation was filed two days before the Delaware declaratory action, the Texas matter takes precedence.[17]
TWC also contends that the first-to-file rule is applicable; however, since the Delaware action was filed before TWC was added to the Texas suit, the Delaware District Court should decide the matter between the two companies.[18] TWC claims that since it was not a party to the Texas litigation on February 2, 2007, it was the first-to-file.[19] TWC maintains that *587 Delaware does not follow the substantial overlap test and prevents duplicative litigation only where the same issues arise between the same parties.[20] TWC asserts that "TWI is a completely different company," which is separately traded on the New York Stock Exchange.[21] Both parties acknowledge that "TWI is an 84% owner of TWC and the remainder of the company is owned by Adelphia Communications Corp.[22] Thus, TWC reiterates that because it was not a party to the Texas litigation, the instant action was the first-filed complaint between TWC and GPNE and, therefore, should be tried in Delaware.
TWC further argues that because forum shopping was GPNE's sole motivation for choosing to litigate in Texas, its preference for that district should be ignored. TWC alleges that "GPNE chose the Eastern District of Texas simply because it is regarded as favorable by plaintiffs in patent cases."[23] TWO notes that all parties to the litigation, including GPNE, are Delaware corporations and only forum shopping explains why the lawsuit was filed anywhere other than Delaware.[24] Finally, TWO argues that there are "sound reasons," such as, the location of the parties, witnesses, and documents, that dictate that the matter should be tried in Delaware.[25]
Motion to Transfer
GPNE argues that this action should be transferred to Texas in the interest of judicial economy and justice since the Texas litigation involving similar issues and parties is currently proceeding.[26] GPNE states that because TWC is now a party to the Texas litigation, it would be economically wasteful to duplicate litigation in this court.[27] GPNE maintains that since judicial effort and resources are being expended in the Texas litigation, "suits involving like defendants who practice similar technology and are accused of infringing the same patent should also proceed in the Eastern District [of Texas]."[28]
TWC counters by arguing that GPNE, as the moving party, has failed to carry the heavy burden of showing that the balance of convenience of the parties and witnesses favors a transfer to Texas.[29] TWC claims that Delaware is a rational and legitimate forum since both companies are incorporated in this state.[30] GPNE does not offer any advantages over pursuing this litigation in Texas, rather than in Delaware. TWC maintains that Delaware is the "most natural and convenient forum," and, as the plaintiff in this case, its choice of forum should be respected and the motion to transfer should be denied.[31]
*588 IV. Analysis
Motion to Dismiss Under the First-to-File Rule
GPNE contends that TWC's declaratory judgment action in this court should be dismissed because this case involves infringement of the same patent, the '406 patent, and concerns the same services and products first-filed in the Texas litigation.[32] The court finds that the present matter should be dismissed in accordance with the first-to-file rule to prevent duplicative lawsuits by different federal courts.
The first-to-file rule gives courts the power to dismiss subsequent claims involving the same parties and the same issues already before another court.[33] The first-to-file rule reduces the possibility of dispositive differences between the jurisdictions and ensures that litigants receive a single determination of their controversy, rather than multiple decisions which may conflict and require separate appeals.[34] Additionally, the rule "helps to avoid the waste involved in duplicative suits, and the delay in providing prompt administrative justice."[35] While the decision is left to the court's discretion, the first-to-file rule "has served to counsel trial judges to exercise their discretion by enjoining the subsequent prosecution of `similar cases . . . in different federal district courts.'"[36]
GPNE's patent infringement case in the Texas litigation was filed on January 31, 2007, two days before TWC filed in this court. Chronologically, GPNE was the first-to-file.[37] TWC was later added as a defendant to the Texas litigation on February 26, 2007. TWC argues that since it was not a defendant in the Texas litigation, it was the first-to-file with the "same" parties and the "same" issues as required by the Third Circuit.[38] Citing APV N. Am., TWC asserts that because the Third Circuit has "expressly rejected" the substantial overlap test, the first-to-file rule requires the parties to be identical in both actions for the first-to-file rule to apply.[39]*589 However, in APV N. Am., where parties in two concurrent suits were not identical, the inquiry hinged on whether the issues in the two cases concerned the "same set of facts," not whether there was substantial overlap between the issues.[40] There, because the two cases implicated different patents, involved different technologies, and, "thus, different facts," the court did not adhere to the first-to-file rule and, accordingly, denied the motion to dismiss.[41] In contrast to the facts of the APV N. Am. case, the issues in the current matter concern the same facts, as well as the same patent, as the Texas litigation.[42]
Third Circuit precedent is also inconsistent with TWC's interpretation of the first-to-file rule, which does not specifically require the exact identity of the parties. Historically, the Third Circuit has applied the first-to-file rule for cases involving the same issues.[43] In E.E.O.C. v. University of Pennsylvania, the court held that "in all cases of federal concurrent jurisdiction, the court which first has possession of the subject must decide it."[44] In Schering Corp. v. Amgen Inc., the District of Delaware interpreted the first-to-file rule as turning "on which court first obtains possession of the subject of the dispute, not the parties of the dispute."[45] Also, the first-to-file rule "serves to prevent a multiplicity of actions and to achieve resolution in a single lawsuit of all disputes from common matters."[46] Furthermore, no relation back analysis, Fed.R.Civ.P. 15, is necessary because GPNE's lawsuit in Texas was the first-filed suit concerning the '406 patent.[47] Since the two cases *590 both involve the same facts and the same patent, trying the matter in two different courts would defeat the reasoning behind the first-to-file rule. Therefore, because the Eastern District of Texas initially had jurisdiction over the subject of the Delaware matter, GPNE's choice of forum should be shown deference and the Delaware case should be dismissed.
Forum Shopping
GPNE's filing of the action in Texas does not appear to be forum shopping or made in bad faith. GPNE asserts that Texas is a "centrally located forum" and is appropriate for the "convenience of the parties and because all three defendants conduct business in different states, have their headquarters in different states, and would be required to travel regardless."[48] A plaintiff's choice of forum should be upheld unless there are rare or extraordinary circumstances that would mandate dismissal or transfer.[49] Forum shopping is considered a proper basis for departing from the first-to-file rule.[50] While the District of Delaware would also undoubtedly be an appropriate jurisdiction, the mere fact that all the parties in the Texas litigation are incorporated in Delaware, "alone will not tip the `balance of convenience' in its favor."[51] No evidence has been presented that GPNE chose to litigate in Texas in bad faith.[52] Thus, without evidence of forum shopping, the first-to-file rule mandates respect for GPNE's choice of forum.
TWC's decision to file suit in Delaware after GPNE's suit against TWI could, however, be considered an example of forum shopping. Even if this case was considered the first-filed, the declaratory judgment action appears to be in anticipation of TWC being added as a defendant in Texas. TWC, itself, makes such assertions in its complaint: "TWC reasonably believes that GPNE is intending to impact the business activities of TWC. . . ."[53] Courts have rejected the first-to-file rule "when the first-filing party instituted suit in one forum in anticipation of imminent judicial proceedings by opposing party's imminent suit in another, less favorable, forum."[54] Since TWI is an 84% owner of TWC, TWC was likely aware of the Texas litigation and the potential to become a defendant in that lawsuit. Therefore, had the instant case been considered the first-filed action, there could potentially be *591 grounds for dismissal or transfer based on forum shopping.
In light of the court's determination that this matter should be dismissed, GPNE's request to stay or transfer is denied as moot.
V. Conclusion
For the reasons stated above:
It is ORDERED AND ADJUDGED that GPNE's motion to dismiss, stay, or transfer TWC's complaint (D.I.7.), is granted in part and denied in part.
1. GPNE's motion to dismiss TWC's complaint is GRANTED.
2. GPNE's motion to stay or transfer this matter is DENIED as moot.

[47]  See Schering, 969 F.Supp. at 267 (holding that a relation back analysis is "misdirected" since an "action is considered first-filed, regardless of the addition of a new party"); see also supra text accompanying notes 33-36, for a discussion of the first-to-file rule's focus on the subject of the controversy, not the individual identity of the parties.

Although the court does not believe that a relation back analysis is necessary, if it were required, the Texas litigation would continue to be the first-filed case. The date of GPNE's original complaint is the controlling date for the first-to-file rule as GPNE's amended complaint, adding TWC as a defendant, relates back to the original complaint. While GPNE does not make this argument, Federal Rule 15(c)(3) allows for amended pleadings to date back to the original complaint. See generally National Foam, Inc. v. Williams Fire & Hazard Control, Inc., 1997 WL 700496, **5-6, 1997 U.S. Dist. LEXIS 16734, at *16-*17 (E.D.Pa. Oct. 29, 1997) ("[W]hile a literal reading of Rule 15(c)(3) might suggest that the mistake element only applies to misnamed or misdescribed parties, `the Rule is widely-understood to allow the addition of new parties that were never originally named or described.'") (citations omitted). Regardless, TWC likely knew of the Texas action and the potential to be added as a defendant. Therefore, using a relation back analysis, the Texas litigation remains the first-filed action.
