MEMORANDUM ORDER
MARY PAT THYNGE, United States Magistrate Judge.
1. INTRODUCTION
In this patent matter, Cordance Corporation ("Cordance") alleges that Amazon.com, Inc. ("Amazon") infringes U.S. Patent No. 6,757,710 ("the '710 patent"). Amazon counterclaimed for declaratory *342 judgment that Cordance infringes its U.S. Patent No. 6,269,369 ("the '369 patent"). Cordance moved to dismiss the counterclaim, for lack of subject matter jurisdiction on the basis of no actual controversy. This memorandum order addresses whether there is an actual case or controversy within the meaning of the Declaratory Judgment Act, 28 U.S.C. § 2201(a).
2. BACKGROUND
The parties develop software and own patents pertaining to on-line Internet based transaction infrastructures.[1] Cordance claims to have invented and commercialized a general purpose identity platform and communications protocol, XRI/XDI, that resellers[2] use to unify contact information on the internet. This technology allows internet users to simplify the process of entering personal information into a website by creating an individual or group "i-name" account.[3] Cordance claims to be the original innovator of XRI technology, and it provides registration services under contract to XDI.org, a not-for-profit industry oversight organization. Cordance also provides technical assistance for its XRI/XDI product and is paid for registering I-brokers who, in turn, profit by signing up individuals and organizations for the service. On June 20, 2006, Cordance and NeuStar, Inc. started the i-name Global Registry Service ("GRS") which provides users with a single permanent unified internet communication address. Cordance acts as corporate administrator and NeuStar supplies i-name communications services. The '710 patent covers i-name technology.
Amazon provides an interactive website that sells goods either directly or through third-party vendors. Amazon's trademarked "1-Click ®" purchasing interface is featured throughout its website. Cordance claims that this interface infringes the '710 patent. Amazon's counterclaim alleges that Cordance's promotion of i-names, including its "Contact Service" or "Unified Address Book" ("UAB")[4] services infringe the '369 patent. That patent, entitled "Networked Personal Contact Manager" covers software which links users and their respective personal "address book" information.
3. LEGAL STANDARD
"A party seeking to base jurisdiction on the Declaratory Judgment Act bears the burden of proving that the facts alleged, `under all the circumstances, show that there is a substantial controversy, between the parties having adverse legal interests, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment.'"[5] Prior to MedImmune, declaratory judgment actions required that there be "both (1) an explicit threat or *343 other action by the patentee, which creates a reasonable apprehension on the part of the declaratory plaintiff that it will face an infringement suit, and (2) present activity which could constitute infringement or concrete steps taken with the intent to conduct such activity."[6] However, "[t]he Supreme Court's opinion in MedImmune represents a rejection of [the] reasonable apprehension of suit test."[7] Jurisdiction over a declaratory judgment action requires:
the dispute be definite and concrete, touching the legal relations of parties having adverse legal interests; and that it be real and substantial and admit 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. Basically, 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.[8]
Evidence of marketing products or services and entering into licensing agreements supports an actual controversy as they are "directed toward making, selling or using subject to an infringement charge or making meaningful preparation for such activities."[9] In addition, "[i]f . . . a party has actually been charged with infringement of the patent, there is, necessarily, a case or controversy adequate to support jurisdiction" at that time.[10] The burden is on the party claiming declaratory judgment jurisdiction to establish that jurisdiction existed when the action was filed and has since continued.[11] Once the initial burden has been met, absent contrary facts, jurisdiction remains.[12]
4. POSITIONS OF THE PARTIES
Cordance challenges the legal sufficiency of Amazon's fourth counterclaim which seeks a declaratory judgment of infringement of Amazon's '369 patent. Cordance argues that Amazon fails to show an actual. controversy, and the counterclaim must be dismissed for lack of jurisdiction.
Cordance contends that Amazon failed to satisfy the two-pronged test; the alleged infringing acts are immediate and real, which place one in reasonable apprehension of suit by the patentee.[13] Cordance *344 argues that it is not actively promoting or developing an address book product and there is no UAB service currently on the market; therefore, there is no infringing act that can be "immediate" and "real."[14] Cordance denies any reasonable apprehension of litigation because Amazon failed to advise of alleged infringement, or threatened litigation, thus there was no refusal to desist. Cordance purports that those elements are necessary for a case and controversy.
Cordance also maintains that the counterclaim is vague and fails to state a claim upon which relief may be granted. It argues that Amazon fails to sufficiently identify which products allegedly infringe and to adequately plead inducement of infringement. According to Cordance, it is only involved in i-name technology and not the Contract or UAB services. Further, because Amazon does not identify any alleged direct infringer, Cordance posits that neither inducement nor contributory infringement exist.
Finally, Cordance proposes that the court in its discretion decline to exercise jurisdiction over the declaratory judgment action. It maintains that no useful purpose would be achieved by allowing Amazon's premature counterclaim, since the UAB service has not been released, or might substantially change prior to release. It purports that Amazon's claims are retaliatory.
Amazon contends that its counterclaim meets the controversy requirement, and would eliminate future uncertainty. It notes that the counterclaim complies with Fed.R.Civ.P. 8(a), sufficiently identifies products accused of infringement, and adequately states a claim of indirect patent infringement.
Amazon maintains that a real and immediate controversy exists between the parties, particularly since Cordance's offensive claim and Amazon's counterclaim concern the same subject matter, i-name technology. Amazbn's counterclaim alleges that the accused products and services "will soon be made available to the public, if not already so available," and accuses Cordance of "standardizing, promoting, commercializing, and/or operating the accused products and services."[15] Because Cordance has created and marketed a standard covering the accused i-name technology, Amazon posits that the acts of *345 standardization constitute infringement.[16] It also contends that selling i-name services through l-brokers is evidence of indirect infringement.
5. DISCUSSION
To succeed in its motion to dismiss, Cordance must show that there is a lack` of a substantial controversy and that Amazon does not have an adverse legal interest of "sufficient immediacy and reality to warrant the issuance of a declaratory judgment."[17] As noted previously herein, the Supreme Court rejected the element of reasonable apprehension; therefore, neither reasonable apprehension of being sued nor threatened legal action are required.
The evidence, shows that Cordance advertised its venture with CeLiberate and promoted the expected introduction of UAB services. Although Cordance removed the UAB reference from its website, the basic architecture and fundamental support for i-name's link to a secure source of personal information on the Internet continues. Assuming Cordance only provided technical assistance for UAB services with CeLiberate introducing the allegedly infringing product, those facts are sufficient to support Amazon's declaratory judgment action. In addition, Cordance's other activities support an actual case and controversy. It developed the architecture by which other companies are able to allegedly infringe Amazon's patent. It created and standardized the XRI/XDI protocol and partnered in creating the XDI.org registry. Cordance promotes i-name technology and receives licensing fees for registering I-brokers, who in turn, enlist individual and corporate users for the i-name technology. Amazon's counterclaim alleges that Cordance presently engages in conduct or has taken concrete steps intending to engage in activities, which would infringe the '369 patent.
A declaratory judgment action is appropriate when "(1) the judgment will serve a useful purpose in clarifying and settling the legal relations in issue, and (2) when it will terminate and afford relief from the uncertainty, insecurity, and controversy giving rise to the proceeding."[18] By exercising jurisdiction, the parties' rights and obligations will be resolved concerning the development and future deployment of the accused related products and services.
Cordance argues that Amazon's pleading fails because it incorrectly identifies UAB as an infringing product or service. Under the Fed.R.Civ.P. 8(a)(2), a plaintiff is required only to make "a short and plain statement of the claim showing that the pleader is entitled to relief." Therefore, Amazon need not identify, in its counterclaim, specific products by name, so long as they are sufficiently described in some way.[19] Amazon describes Cordance services with adequate specificity.
Cordance maintains that since it removed all UAB references from its website, a controversy between the parties no longer exists. Once a controversy is shown, subsequent events may divest the trial court of jurisdiction; however, no information regarding cessation of other services *346 that may be directly or indirectly infringing has been provided.
6. CONCLUSION
For the reasons contained herein, Cordance's motion to dismiss Amazon's counterclaim four (D.I. 27) is DENIED.

[13]  Cordance relies on the legal standard in Lang v. Pacific Marine Supply Co., 895 F.2d 761, 764 (Fed.Cir.1990). It distinguishes Lang from MedImmune, by asserting that Lang applies to declaratory judgment of infringement while MedImmune is limited to declaratory judgment of non-infringement. Lang held that "[t]o meet the controversy requirement in a declaratory judgment suit by a patentee against an alleged future infringer, two elements must be present: (1) the defendant must be engaged in an activity directed toward making, selling, or using subject to an infringement charge under 35 U.S.C. § 271(a) (1982), or be making meaningful preparation for such activity; and (2) acts of the defendant Must indicate a refusal to change the course of its actions in the face of acts by the patentee sufficient to create a reasonable apprehension that a suit will be forthcoming." Lang, 895 F.2d at 764. In MedImmune, the Supreme Court determined that a party seeking jurisdiction through the Declaratory Judgment Act has the burden "under all the circumstances, [to] show that there is a substantial controversy, between the parties having adverse legal interests, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment." MedImmune, 127 S.Ct. at 771.
