[1374]*1374LINN, Circuit Judge.
SanDisk Corporation (“SanDisk”) appeals from a decision of the U.S. District Court for the Northern District of California granting STMicroelectronics’ (“ST’s”) motion to dismiss SanDisk’s second through twenty-ninth claims relating to declaratory judgment of noninfringement and invalidity for failure to present an actual controversy. See SanDisk Corp. v. STMicroelectronics, Inc., No. 04-CV-04379 (N.D.Cal. Jan. 20, 2005). Because the district court erred in dismissing the declaratory judgment claims for lack of subject matter jurisdiction, we vacate the judgment and remand the case to the district court.
I. BACKGROUND
SanDisk is in the flash memory storage market and owns several patents related to flash memory storage products. ST, traditionally in the market of semiconductor integrated circuits, more recently entered the flash memory market and has a sizeable portfolio of patents related to flash memory storage products. On April 16, 2004, ST’s vice president of intellectual property and licensing, Lisa Jorgenson (“Jorgenson”), sent a letter to SanDisk’s chief executive officer requesting a meeting to discuss a cross-license agreement. The letter listed eight patents owned by ST that Jorgenson believed “may be of interest” to SanDisk. SanDisk, slip op. at 2; Letter from Jorgenson to SanDisk (Apr. 16, 2004). On April 28, 2004, SanDisk responded that it would need time to review the listed patents and would be in touch in several weeks to discuss the possibility of meeting in June.
On July 12, 2004, having heard nothing further from SanDisk, Jorgenson sent a letter to SanDisk reiterating her request to meet in July to discuss a cross-license agreement and listing four additional ST patents that “may also be of interest” to SanDisk. SanDisk, slip op. at 2; Letter from Jorgenson to SanDisk (July 12, 2004). On July 21, 2004, SanDisk’s chief intellectual property counsel and senior director, E. Earle Thompson (“Thompson”), responded to ST’s letter by informing Jorgenson of his “understanding that both sides wish to continue ... friendly discussions” such as those between the business representatives in May and June. San-Disk, slip op. at 2-3; Letter from Thompson to Jorgenson (July 21, 2004). The discussions of May and June that Thompson referred to were discussions among managers and vice presidents of SanDisk and ST at business meetings held on May 18, 2004, and June 9, 2004, to explore the possibility of ST’s selling flash memory products to SanDisk. The business meetings were unrelated to any patents. Thompson also requested that Jorgenson join the next business meeting on August 5, 2005. On July 27, 2004, Jorgenson replied, again urging a meeting with Thompson, noting that it was “best to separate the business discussions from the patent license discussions.” SanDisk, slip op. at 3; Letter from Jorgenson to Thompson (July 27, 2004).
On August 5, 2004, when the business representatives next met, SanDisk presented an analysis of three of its patents and orally offered ST a license. ST declined to present an analysis of any of its patents, stating instead that any patent and licensing issues should be discussed in a separate meeting with Jorgenson. Later that same day, Thompson wrote a letter to Jorgenson objecting to separating business and intellectual property issues and stating that “[i]t has been SanDisk’s hope and desire to enter into a mutually beneficial discussion without the rattling of sabers.” SanDisk, slip op. at 4; Letter from Thompson to Jorgenson (Aug. 5, 2004). [1375]*1375On August 11, 2004, Jorgenson replied, stating that it was her understanding that the parties were going to have a licensing/intellectual property meeting later that month “to discuss the possibility for a patent cross-license.” Letter from Jorgenson to Thompson (Aug. 11, 2004). She said that SanDisk should come to that meeting prepared to present an analysis of the three SanDisk patents it identified during the August 5th business meeting, as well as “any infringement analyses of an ST device or need for ST to have a license to these patents.” Id. She also said that ST would be prepared at that meeting to discuss the twelve patents identified in her prior letters. In closing, Jorgenson said that ST was “looking] forward to open and frank discussions with SanDisk concerning fair and reasonable terms for a broad cross-license agreement.” Id.
On August 27, 2004, the licensing meeting .was held. Jorgenson, two ST licensing attorneys, and three technical experts retained by ST to perform the infringement analyses of SanDisk’s products, attended on behalf of ST. Thompson and an engineer attended on behalf of SanDisk. At the meeting, Jorgenson requested that the parties’ discussions be treated as “settlement discussions” under Federal Rule of Evidence 408.1 SanDisk, slip op. at 5. ST then presented a slide show which compared statistics regarding SanDisk’s and ST’s patent portfolios, revenue, and research and development expenses, and listed SanDisk’s various “unlicensed activities.” Id. This slide show was followed by a four— to five-hour presentation by ST’s technical experts, during which they identified and discussed the specific claims of each patent and alleged that they were infringed by SanDisk. According to Thompson, the presentation by ST’s technical experts included “mapping] the elements of each of the allegedly infringed claims to the aspects of the accused San-Disk products alleged to practice the elements.” Id. Thompson declares that “the experts liberally referred to SanDisk’s (alleged) infringement of [ST’s] products.” Id., slip op. at 5-6. SanDisk’s engineer then made a presentation, describing several of SanDisk’s patents and analyzing how a semiconductor chip product sold by ST infringes. Id., slip op. at 6.
At the end of the meeting, Jorgenson handed Thompson a packet of materials containing, for each of ST’s fourteen patents under discussion, a copy of the patent, reverse engineering reports for certain of SanDisk’s products, and diagrams showing how elements of ST’s patent claims cover SanDisk’s products. According to San-Disk, Jorgenson indicated (in words to this effect):
I know that this is material that would allow SanDisk to DJ [ST] on. We have had some internal discussions on whether I should be giving you a copy of these materials in light of that fact. But I have decided that I will go ahead and give you these materials.
[1376]*1376Id. Jorgenson further told Thompson that “ST has absolutely no plan whatsoever to sue SanDisk.” Id. Thompson responded to Jorgenson that “SanDisk is not going to sue you on Monday” and that another meeting might be appropriate. Id.
On September 1, 2004, Jorgenson wrote to Thompson, enclosing copies of ST’s general slide presentation from the August meeting and also enclosing a hard copy booklet containing each of the engineering reports “for each claim on all products where ST demonstrated coverage by the 14 ST patents to-date [sic].” Id.; Letter from Jorgenson to Thompson (Sept. 1, 2004). Jorgenson requested that SanDisk provide ST with a copy of SanDisk’s presentation and information about the three SanDisk patents presented. On September 8, 2004, Thompson replied by e-mail, confirming receipt of the package from ST, attaching a copy of SanDisk’s presentation, indicating it was his “personal feeling ... that we have got to trust one another during these negotiations,” and seeking a non-disclosure agreement. SanDisk, slip op. at 6-7; E-mail from Thompson to Jorgenson (Sept. 8, 2004). Thompson also wrote “I still owe you the rates quoted.” Id.
On September 15, 2004, Thompson again corresponded with Jorgenson, this time by letter, enclosing a confidential version of SanDisk’s cross licensing offer, which noted that the offer would expire on September 27, 2004. SanDisk, slip op. at 7; Letter from Thompson to Jorgenson (Sept. 15, 2004). Jorgenson destroyed this confidential offer and did not retain a copy, and, on September 16, 2004, sent Thompson an email requesting that a non-confidential version be sent for ST’s consideration. SanDisk, slip op. at 7; E-mail from Jor-genson to Thompson (Sept. 16, 2004). SanDisk refused to send a non-confidential version. Instead, on September 27, 2004, Thompson offered to send another confidential version, or to communicate the offer orally. E-mail from Thompson to Jor-genson (Sept. 27, 2004). Thompson also indicated that SanDisk did not need additional information regarding ST’s patents because SanDisk was “quite comfortable with its position” and that it was “time to let our business people talk and see if a peaceful resolution is possible.” Id. On September 28, 2004, Jorgenson repeated her request for a written non-confidential version of SanDisk’s licensing offer. San-Disk, slip op. at 7-8; E-mail from Jorgen-son to Thompson (Sept. 28, 2004). The following day, Thompson e-mailed Jorgen-son another confidential version of San-Disk’s offer. SanDisk, slip op. at 8.
On October 15, 2004, after several further e-mails and phone calls between the business representatives trying to establish another meeting, SanDisk filed the instant lawsuit. SanDisk alleged infringement of one of its patents and sought a declaratory judgment of noninfringement and invalidity of the fourteen ST patents that had been discussed during the cross licensing negotiations. On December 3, 2004, ST filed a motion to dismiss San-Disk’s declaratory judgment claims for lack of subject matter jurisdiction, maintaining that there was no actual controversy at the time SanDisk filed its complaint.
The district court granted ST’s motion to dismiss, holding that no actual controversy existed for purposes of the Declaratory Judgment Act because SanDisk did not have an objectively reasonable apprehension of suit, even though it may have subjectively believed that ST would bring an infringement suit. See id., slip op. at 14. The district court reasoned that “San-Disk has presented no evidence that ST threatened it with litigation at any time during the parties’ negotiations, nor has SanDisk shown other conduct by ST rising [1377]*1377to a level sufficient to indicate an intent on the part of ST to initiate an infringement action.” Id. The district court found that the studied and determined infringement analyses that ST presented to SanDisk did not constitute the requisite “express charges [of infringement] carrying with them the threat of enforcement.” Id., slip op. at 14-15. The district court also found that the totality of the circumstances did not evince an actual controversy because ST told SanDisk that it did not intend to sue SanDisk for infringement. Id., slip op. at 15-16. In a footnote, the court indicated that, as an alternative basis for its ruling, even if it did have jurisdiction, it would exercise its discretion and decline to hear the case. Id., slip op. at 17 n. 30.
SanDisk appealed the dismissal to this court. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1) (2000).
II. DISCUSSION
A. Standard of Review
For purposes of Article III, this court reviews a dismissal of a patent claim for lack of an actual controversy upon a particular set of facts as a question of law subject to plenary appellate review. Arrowhead Indus. Water, Inc. v. Ecolochem, Inc., 846 F.2d 731, 735 (Fed.Cir.1988). This court reviews the underlying factual findings for clear error. Gen-Probe Inc. v. Vysis, Inc., 359 F.3d 1376, 1379 (Fed.Cir.2004).
B. Analysis
SanDisk argues that the district court erred as a matter of law by requiring an express accusation of patent infringement coupled with an explicit threat of judicial enforcement to support declaratory judgment jurisdiction, and that, under the correct legal standard articulated by this court in Arrowhead, 846 F.2d at 736, the facts of this case illustrate that San-Disk’s apprehension of an infringement suit was objectively reasonable. SanDisk asserts that the infringement analysis presented by ST and its experts at the August 27, 2004 licensing meeting constituted an allegation of infringement and that the totality of the circumstances shows that ST’s conduct gave rise to an actual case or controversy. SanDisk further points out that negotiations regarding licensing had ceased by the time SanDisk filed its claims for declaratory judgment.
ST counters that the district court applied the correct legal standard and argues that SanDisk ignores the line of cases that have followed and interpreted Arrowhead. ST asserts that the cases following Arrowhead reveal that the bare mention of infringement, particularly during license negotiations, is not sufficient to meet the standard set forth in Arrowhead. ST asserts that its conduct at the August 27, 2004 licensing meeting was to strengthen its position during licensing negotiations and that, under the totality of the circumstances, SanDisk has not shown that ST’s conduct gave rise to declaratory judgment jurisdiction. Moreover, ST argues that the district court did not abuse its discretion when it concluded, as an alternative basis for its ruling, that it would exercise discretion to decline to decide SanDisk’s claims.
1. Case or Controversy
The first question we address is whether the facts alleged in this case show that there is a case or controversy within the meaning of the Declaratory Judgment Act, 28 U.S.C. § 2201(a).
The Declaratory Judgment Act provides, in relevant part, that
[i]n a case of actual controversy within its jurisdiction ... any court of the United States, upon the filing of an appropri[1378]*1378ate pleading, may declare the rights and other legal relations of any interested party seeking such declaration, whether or not further relief is or could be sought.
28 U.S.C. § 2201(a). The “actual controversy” requirement of the Declaratory Judgment Act is rooted in Article III of the Constitution, which provides for federal jurisdiction over only “cases and controversies.” Thus, our jurisdiction extends only to matters that are Article III cases or controversies.
The Supreme Court, in the context of a patent license dispute, recently examined Article Ill’s case or controversy requirement as it relates to the Declaratory Judgment Act. See MedImmune, Inc. v. Genentech, Inc., — U.S. —, 127 S.Ct. 764, 166 L.Ed.2d 604 (2007). In MedImmune, the Supreme Court considered “whether Article Ill’s limitation of federal courts’ jurisdiction to ‘Cases’ and ‘Controversies,’ reflected in the ‘actual controversy’ requirement of the Declaratory Judgment Act, 28 U.S.C. § 2201(a), requires a patent licensee to terminate or be in breach of its license agreement before it can seek a declaratory judgment that the underlying patent is invalid, unenforceable, or not infringed.” Id. at 767.
The Supreme Court began its analysis with the recognition that, where threatened action by government is concerned, [the Court] do[es] not require a plaintiff to expose himself to liability before bringing suit to challenge the basis for the threat — for example, the constitutionality of a law threatened to be enforced. The plaintiffs own action (or inaction) in failing to violate the law eliminates the imminent threat of prosecution, but nonetheless does not eliminate Article III jurisdiction.
Id. at 772. The Supreme Court quoted its earlier decision in Maryland Casualty Co. v. Pacific Coal & Oil Co., 312 U.S. 270, 273, 61 S.Ct. 510, 85 L.Ed. 826 (1941), where the Court stated that “the question in each case is whether the facts alleged, under all the circumstances, show that there is a substantial controversy, between parties having adverse legal interests, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment.” MedImmune, 127 S.Ct. at 771. The Supreme Court emphasized that Article III requires that the dispute at issue be “ ‘definite and concrete, touching the legal relations of parties having adverse legal interests’; and that it be ‘real and substantial’ and ‘admi[t] of specific relief through a decree of a conclusive character, as distinguished from an opinion advising what the law would be upon a hypothetical state of facts.’ ” Id. (quoting Aetna Life Ins. Co. v. Haworth, 300 U.S. 227, 240-41, 57 S.Ct. 461, 81 L.Ed. 617 (1937)). The Supreme Court stated that, when faced with a genuine threat of enforcement that the government will penalize a certain private action, Article III “d[oes] not require, as a prerequisite to testing the validity of the law in a suit for injunction, that the plaintiff bet the farm, so to speak, by taking the violative action.” Id. at 772 (citations omitted). As the Supreme Court noted, “the declaratory judgment procedure is an alternative to pursuit of the arguably illegal activity.” Id. (quotation marks omitted). The Supreme Court clarified that, although a declaratory judgment plaintiff may eliminate an “imminent threat of harm by simply not doing what he claimed the right to do[,] ... [t]hat did not preclude subject-matter jurisdiction [where] the threat-eliminating behavior was effectively coerced.” Id. “The dilemma posed by that coercion — putting the challenger to the choice between abandoning his rights or risking prosecution — is a dilemma that it was the very purpose of the Declaratory [1379]*1379Judgment Act to ameliorate.” Id. at 773 (internal quotation marks omitted).
The Supreme Court then applied these principles to the facts of the case and remarked that “the requirements of [a] case or controversy are met where payment of a claim is demanded as of right and where payment is made, but where the involuntary or coercive nature of the exaction preserves the right to recover the sums paid or to challenge the legality of the claim.” Id. (internal quotation marks omitted). The Supreme Court held that “[t]he rule that a plaintiff must destroy a large building, bet the farm, or (as here) risk treble damages and the loss of 80 percent of its business, before seeking a declaration of its actively contested legal rights finds no support in Article III.” Id. at 775.
With regard to patent disputes, prior to Medlmmune, this court articulated a two-part test that first considers whether conduct by the patentee creates a reasonable apprehension on the part of the declaratory judgment plaintiff that it will face an infringement suit, and second examines whether conduct by the declaratory judgment plaintiff amounts to infringing activity or demonstrates concrete steps taken with the intent to conduct such activity. See Arrowhead, 846 F.2d at 736. The Supreme Court, in MedImmune, addressed the “reasonable apprehension of suit” aspect of this court’s two-part test and concluded that it conflicts with Aetna Life Insurance and Maryland Casualty, and is in tension with Cardinal Chemical Co. v. Morton International, Inc., 508 U.S. 83, 98, 113 S.Ct. 1967, 124 L.Ed.2d 1 (1993). See MedImmune, 127 S.Ct. at 774 n. 11.
In Aetna Life Insurance, an insurer sought a declaratory judgment that the insured was not relieved of his duty to continue to pay insurance premiums and that, since the insured had stopped making the payments, the insurance policy had lapsed. In that case, the Supreme Court first upheld the constitutionality of the federal Declaratory Judgment Act. 300 U.S. at 240-41, 57 S.Ct. 461. The Supreme Court then held that, although the insured party gave no indication that he would file suit, id. at 239, 57 S.Ct. 461, the case nevertheless presented a controversy under Article III because the parties had taken adverse positions with regard to their obligations, each side presenting a concrete claim of a specific right — the insured claiming that he had become disabled and therefore was relieved of making insurance premium payments and the insurer claiming that the insured was not disabled and that the failure to make payments caused the policy to lapse, id. at 244, 57 S.Ct. 461. Similarly, in Maryland Casualty, the declaratory judgment plaintiff, an insurance company which had agreed to indemnify and defend the insured against actions brought by third parties against the insured, sought a declaration that it had no duty to defend or to indemnify the insured. 312 U.S. at 272, 61 S.Ct. 510. In that case, the insured could not have sued the declaratory judgment plaintiff without first obtaining a judgment against the third party and the underlying action against the third party “[a]pparently ... ha[d] not proceeded to judgment.” Id. at 271, 61 S.Ct. 510. Nevertheless, the Supreme Court held that “[i]t is clear that there is an actual controversy between petitioner and the insured” since the insured was in the process of seeking a judgment and had a statutory right to proceed against the declaratory judgment plaintiff if such judgment were obtained and not satisfied. Id. at 274, 61 S.Ct. 510. Finally, in Cardinal Chemical, the Supreme Court held that this court’s affirmance of a judgment of noninfringement does not necessarily moot a declaratory judgment [1380]*1380counterclaim of patent invalidity. 508 U.S. at 98, 113 S.Ct. 1967. The Supreme Court’s rationale for holding that the declaratory judgment action can proceed consistent with Article III was that a contrary result would create the potential for relitigation or uncertainty with regard to the validity of patents and would be contrary to Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation, 402 U.S. 313, 91 S.Ct. 1434, 28 L.Ed.2d 788 (1971).
The Supreme Court’s opinion in MedImmune represents a rejection of our reasonable apprehension of suit test.2 The Court first noted that “the continuation of royalty payments makes what would otherwise be an imminent threat at least remote, if not nonexistent.... Petitioner’s own acts, in other words, eliminate the imminent threat of harm.” MedImmune, 127 S.Ct. at 772. The Court nonetheless concluded that declaratory judgment jurisdiction existed relying in particular on its earlier decision in Altvater v. Freeman, 319 U.S. 359, 63 S.Ct. 1115, 87 L.Ed. 1450 (1943). There, the patentee brought suit to enjoin patent infringement, and the accused in-fringer filed declaratory judgment counterclaims of invalidity. The district court found that there was no infringement and that the patent was invalid. Id. at 362, 63 S.Ct. 1115. The appellate court affirmed the finding of noninfringement but vacated the finding of invalidity as moot. Id. The Supreme Court held that the declaratory judgment counterclaims were not mooted by the finding of noninfringement. Id. at 365-66, 63 S.Ct. 1115. In finding declaratory judgment jurisdiction in Medlmmune, the Court specifically addressed and rejected our reasonable apprehension test:
[e]ven if Altvater could be distinguished as an “injunction” case, it would still contradict the Federal Circuit’s “reasonable apprehension of suit” test (or, in its evolved form, the “reasonable apprehension of imminent suit” test, Teva Pharm. USA, Inc. v. Pfizer, Inc., 395 F.3d 1324, 1333 (2005)). A licensee who pays royalties under compulsion of an injunction has no more apprehension of imminent harm than a licensee who pays royalties for fear of treble damages and an injunction fatal to his business. The reasonable-apprehension-of-suit test also conflicts with our decisions in Maryland Casualty Co. v. Pacific Coal & Oil Co., 312 U.S. 270, 273, 61 S.Ct. 510, 85 L.Ed. 826 (1941), where jurisdiction obtained even though the collision-victim defendant could not have sued the declaratory-judgment plaintiff-insurer without first obtaining a judgment against the insured; and Aetna Life Ins. Co. v. Haworth, 300 U.S. 227, 239, 57 S.Ct. 461, 81 L.Ed. 617 (1937), where jurisdiction obtained even though the very reason the insurer sought declaratory relief was that the insured had given no indication that he would file suit. It is also in tension with Cardinal Chemical Co. v. Morton Int’l, Inc., 508 U.S. 83, 98, 113 S.Ct. 1967, 124 L.Ed.2d 1 (1993), which held that appellate affirmance of a judgment of noninfringement, eliminating any apprehension of suit, does not moot a declaratory judgment counterclaim of patent invalidity.
MedImmune, 127 S.Ct. at 774 n. 11.
The Supreme Court in Medlm-mune addressed declaratory judgment jurisdiction in the context of a signed license. In the context of conduct prior to the existence of a license, declaratory [1381]*1381judgment jurisdiction generally will not arise merely on the basis that a party learns of the existence of a patent owned by another or even perceives such a patent to pose a risk of infringement, without some affirmative act by the patentee. But Article III jurisdiction may be met where the patentee takes a position that puts the declaratory judgment plaintiff in the position of either pursuing arguably illegal behavior or abandoning that which he claims a right to do. We need not define the outer boundaries of declaratory judgment jurisdiction, which will depend on the application of the principles of declaratory judgment jurisdiction to the facts and circumstances of each case. We hold only that where a patentee asserts rights under a patent based on certain identified ongoing or planned activity of another party, and where that party contends that it has the right to engage in the accused activity without license, an Article III case or controversy will arise and the party need not risk a suit for infringement by engaging in the identified activity before seeking a declaration of its legal rights. See id. Contra Cygnus Therapeutics Sys. v. ALZA Corp., 92 F.3d 1153 (Fed.Cir.1996) (holding that declaratory judgment jurisdiction was not supported where the “patentee does nothing more than exercise its lawful commercial prerogatives and, in so doing, puts a competitor in the position of having to choose between abandoning a particular business venture or bringing matters to a head by engaging in arguably infringing activity”).
Our holding is consistent with decisions of other courts in various cases unrelated to patent licensing. See, e.g., Bancroft & Masters, Inc. v. Augusta Nat'l Inc., 223 F.3d 1082, 1085 (9th Cir.2000) (finding declaratory judgment jurisdiction based on trademark owner’s cease and desist letter despite the fact that trademark owner offered to waive all trademark infringement and related claims); GNB Battery Tech., Inc. v. Gould, Inc., 65 F.3d 615, 620 (7th Cir.1995) (finding declaratory judgment jurisdiction where declaratory judgment plaintiff filed action in anticipation of potential action by the defendant based on new legislation although the defendant had not indicated whether or when it may act); Kunkel v. Cont’l Cas. Co., 866 F.2d 1269, 1274 (10th Cir.1989) (affirming exercise of declaratory judgment jurisdiction over suit seeking declaratory judgment for determination of value of insurance coverage even though existence of coverage remained dependent upon the outcome of a collateral action and noting that “[t]he contingent nature of the right or obligation in controversy will not bar a litigant from seeking declaratory relief when the circumstances reveal a need for present adjudication”); see also IMS Health, Inc. v. Vality Tech. Inc., 59 F.Supp.2d 454 (E.D.Pa.1999) (holding that requirements for declaratory judgment jurisdiction were satisfied where copyright holder had not indicated it was going to file suit but had taken positions and made demands such that the declaratory judgment plaintiff justifiably believed that copyright holder might take such action in the future and noting that “[i]t is quite possible for two parties to simultaneously consider nonlitigious settlement of a dispute, while at the same time maintaining an awareness that either settlement is improbable or that litigation is equally likely”); N. Shore Gas Co. v. Salomon, Inc., 896 F.Supp. 786, 789-90 (N.D.Ill. 1995) (finding declaratory judgment jurisdiction where plaintiff, “rather than wait an indefinite time to be sued,” filed suit after the settlement discussions came to an impasse); J. Lyons & Co. Ltd. v. Republic of Tea, Inc., 892 F.Supp. 486 (S.D.N.Y.1995) (dismissing trademark holder’s later-filed infringement action in favor of previously filed declaratory judgment actions [1382]*1382where declaratory judgment plaintiffs had received cease and desist letters and no settlement appeared agreeable, despite the fact that trademark holder did not give actual notice of litigation); Kmart Corp. v. Key Indus., Inc., 877 F.Supp. 1048, 1055 (E.D.Mich.1994) (holding that ongoing settlement negotiations did not require dismissal of declaratory judgment action where the evidence indicated that the trademark holder would accept no settlement short of total capitulation); Agridyne Tech., Inc. v. W.R. Grace & Co., 863 F.Supp. 1522 (D.Utah 1994) (refusing to dismiss declaratory judgment action where plaintiff justifiably believed that further settlement negotiations would be fruitless).
Under the facts alleged in this case, SanDisk has established an Article III case or controversy that gives rise to declaratory judgment jurisdiction. ST sought a right to a royalty under its patents based on specific, identified activity by SanDisk. For example, at the August 27, 2004 licensing meeting, ST presented, as part of the “license negotiations,” a thorough infringement analysis presented by seasoned litigation experts, detailing that one or more claims of its patents read on one or more of SanDisk’s identified products. At that meeting, ST presented SanDisk with a detailed presentation which identified, on an element-by-element basis, the manner in which ST believed each of SanDisk’s products infringed the specific claims of each of ST’s patents. During discussions, the experts liberally referred to SanDisk’s present, ongoing infringement of ST’s patents and the need for SanDisk to license those patents. ST also gave SanDisk a packet of materials, over 300 pages in length, containing, for each of ST’s fourteen patents under discussion, a copy of the patent, reverse engineering reports for certain of SanDisk’s products, and diagrams showing a detailed infringement analysis of SanDisk’s products. ST communicated to SanDisk that it had made a studied and determined infringement determination and asserted the right to a royalty based on this determination. SanDisk, on the other hand, maintained that it could proceed in its conduct without the payment of royalties to ST. These facts evince that the conditions of creating “a substantial controversy, between parties having adverse legal interest, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment” were fulfilled. Md. Cas., 312 U.S. at 273, 61 S.Ct. 510. SanDisk need not “bet the farm,” so to speak, and risk a suit for infringement by cutting off licensing discussions3 and continuing in the identified activity before seeking a declaration of its legal rights. See MedImmune, 127 S.Ct. at 774 n. 11. Contra Phillips Plastics Corp. v. Kato Hatsujou Kabushiki Kaisha, 57 F.3d 1051 (Fed.Cir.1995) (“When there are proposed or ongoing license negotiations, a litigation controversy normally does not arise until the negotiations have broken down.”).
2. Promise Not to Sue
We next address whether Jorgen-son’s direct and unequivocal statement that “ST has absolutely no plan whatsoever to sue SanDisk” eliminates any actual controversy and renders SanDisk’s declaratory judgment claims moot.
We decline to hold that Jorgenson’s statement that ST would not sue SanDisk [1383]*1383eliminates the justiciable controversy created by ST’s actions, because ST has engaged in a course of conduct that shows a preparedness and willingness to enforce its patent rights despite Jorgenson’s statement. Having approached SanDisk, having made a studied and considered determination of infringement by SanDisk, having communicated that determination to SanDisk, and then saying that it does not intend to sue, ST is engaging in the kinds of “extra-judicial patent enforcement with scare-the-customer-and-run tactics” that the Declaratory Judgment Act was intended to obviate. Arrowhead, 846 F.2d at 735. ST’s statement that it does not intend to sue does not moot the actual controversy created by its acts. See Md. Cas., 312 U.S. at 273, 61 S.Ct. 510 (jurisdiction obtained even though the defendant could not have sued the declaratory judgment plaintiff).
3. District Court’s Discretion
Although the district court is given the discretion, in declaratory judgment actions, to dismiss the case, there are boundaries to that discretion. See Wilton v. Seven Falls Co., 515 U.S. 277, 289, 115 S.Ct. 2137, 132 L.Ed.2d 214 (1995). “When there is an actual controversy and a declaratory judgment would settle the legal relations in dispute and afford relief from uncertainty or insecurity, in the usual circumstance the declaratory judgment is not subject to dismissal.” Genentech v. Eli Lilly & Co., 998 F.2d 931, 937 (Fed.Cir.1993). Furthermore, the exercise of discretion must be supported by a sound basis for refusing to adjudicate an actual controversy. See Elecs. for Imaging, Inc. v. Coyle, 394 F.3d 1341, 1345 (Fed.Cir.2005); Capo, Inc. v. Dioptics Med. Prod., Inc., 387 F.3d 1352, 1357 (Fed.Cir.2004).
In this ease, the district court noted, without explanation in a footnote, that “[a]s an alternative basis for its ruling, the Court concludes that even if it had subject matter jurisdiction over the instant claims, it would exercise its discretion and decline to decide them.” SanDisk, slip op. at 17 n. 30. That decision, however, was made in the context of our “reasonable apprehension” precedent without the benefit of the Supreme Court’s views in MedImmune. Given the change reflected in MedImmune and our holding in this case, we discern little basis for the district court’s refusal to hear the case and expect that in the absence of additional facts, the case will be entertained on the merits on remand.
CONCLUSION
For the above reasons, we conclude that the dismissal was improperly granted. The dismissal is vacated, and the case is remanded for further proceedings consistent with this opinion.
