MEMORANDUM OPINION

SUE L. ROBINSON, Chief Judge.

I. INTRODUCTION

Plaintiff Bavarian Nordic A/S (“Bavarian Nordic”) is a corporation duly organized and existing under the laws of the nation of Denmark; it maintains its principal place of business in Kvistgard, Denmark. Plaintiff Anton Mayr (“Dr.Mayr”) is a German national who resides in Starn-berg, Germany. Plaintiffs allege in the instant litigation that defendants Acambis Inc. and Acambis Pic (collectively, “Acam-bis” or “defendants”) are liable for tortious interference and unfair competition based on defendants’ commercial use of a certain virus allegedly owned by plaintiffs, that is, “MVA 572 FHE — 22.02.1974” (“MVA 572”). Defendant Acambis Inc. is a corporation duly organized and existing under the laws of the State of Delaware, with its principal place of business located in Cambridge, Massachusetts. Defendant Acam-bis Pic is a corporation organized and existing under the laws of the nation of the United Kingdom, with its principal place of business located in Cambridge, United Kingdom.

Plaintiffs have moved for summary judgment on their tortious conversion claim. Defendants have moved for summary judgment on all claims. The court has jurisdiction over these matters pursuant to 28 U.S.C. §§ 1331 and 1332.

II. FACTS 1

This litigation has its genesis in scientific research commenced at the Bavarian State Vaccination Institute (“the Institute”) in the 1950s. From 1955 to 1959, plaintiff Dr. Mayr was an employee of the Institute, working under a Professor Herr-lich. At the time, the smallpox vaccination was compulsory in the State of Bavaria (and elsewhere) and Professor Herrlich was responsible for its safe manufacture through the Institute. Professor Herrlich believed that the vaccine virus deposited at the Ankara (Turkey) Vaccination Institute was a better, safer virus from which to produce vaccine; he also believed that “by continuing the passaging [ 2 ] of the virus, *357 there would be a much reduced risk of post-vaccination encephalitis.” (D.I. 113, ex. 5 at 14) At Professor Herrlich’s direction, therefore, Dr. Mayr obtained a sample virus from Ankara (the “CVA virus”) and “passaged the CVA virus continuously.” (Id. at 13)

In 1971, the “Free State of Bavaria, represented by the Bavarian State Interior Ministry,” filed a patent application in the Federal Republic of Germany. The named inventors were Prof. Dr. Helmut Stiekl and Prof. Dr. Anton Mayr, and the title was “Method for Small Pox Vaccination.” (D.I. 123, ex. 7) In the specification, the invention is described as follows:

[T]he invention is based on the knowledge that, in order to avoid the disadvantages of all previously known vaccination methods against small pox, it is deciding to use a vaccine causing no cutaneous vaccination reactions, such as a formulation of a vaccination pustule. According to the invention this is attained in a method for a vaccination against small pox such that the vaccination occurs intracutaneously with an attenuated, modified vaccine. Advantageously, the vaccinia-virus Ankara is used, here, which is bread [sic] in more than 500 passages in chicken fibroblast-cells so that a modified, genetically uniform vaccinia virus is provided, which is weakened in its reactogenity and virulence by said cell passages.

(Id. at 4-5 (emphasis in original)) The dependent claim is “[a] vaccine according to claim 1, characterized in that the vae-cine is formed by using the vaccinia virus Ankara, which is bread [sic] in more than 500 passages in chicken-fibroblast cells.” (Id. at 7) By patent application filed in the Swiss Confederation in September 1972, once again the “Free State of Bavaria, represented by the Bavarian Ministry of the Interior” asserted that the inventor, Prof. Dr. Stiekl, invented a “[p]rocess for culturing a virus intended for producing an inoculant against smallpox” with a preferred embodiment of the process being “characterized in that the Ankara vaccinia virus is cultured in at least 400, preferably more than 500, cell culture passages in swine kidney cells.” (D.I. 123, ex. 8)

By 1974, Dr. Mayr was the director of the Institute for Medical Microbiology, Infectious and Epidemic Diseases, Veterinary Faculty, University of Munich (“the University”). (D.I. 116, ex. C) In that year, Dr. Mayr co-authored two articles about MVA. One, entitled “Passage History, Properties, and Use of the Attenuated Vaccinia Virus Strain MVA,” was co-authored by “A. Mayr, V. Hochstein-Mintzel and H. Stiekl.” In describing the passage history of the MVA virus, the authors wrote:

Since [1963], the CVA-FHE virus was submitted to further passages on FHE cultures. By now, culture passage 570 has been reached and the virus appears to be genetically uniform and stable. The last passages were again cloned by the serial plaque dilution technique. The eggs used for the plaque dishes originated in an approved leukosis-free *358 fowl population. After clinical testing in humans, the CVA-FHE virus was designated MVA Virus — modified vaccinia virus Ankara — starting with the 516th FHE passage, due to its stability and its changed properties and in order to avoid confusing it with other attenuated vacci-nia strains.

(D.I. 116, ex. E at 4 (emphasis in original)) The article goes on to claim that “[t]he MVA virus is suitable for active immuno-prophylaxis against all human and animal diseases caused by orthopoxvirus-es” and describes the testing done on animals to prove the claim. (Id. at 9-11) “On the application of the MVA virus in humans,” the authors “provided a separate report” (Id. at 11), that is, the second article entitled “MVA Vaccination Against Smallpox.” The second article addresses the clinical testing of MVA by the Institute and the University. By way of background, the authors of the article 3 explained that,

[flor many years, an attenuated vaccinia virus has been under testing in animal experiments at the ... Institute. This virus, which has been referred to in the course of these experiments as the “MVA” strain (modified vaccinia virus Ankara strain) has proven to be aviral in animal experiments. On the basis of findings on primates, it has been used to produce vaccine and has ultimately been used clinically on patients. The findings obtained in this regard are the subject matter of the present article.

(D.I. 123, ex. 5 at AC0012993) The article goes on to state that the

[vjaccinia virus Ankara strain was attenuated by Mayr in continuous passages on cell cultures of embryonal chick fibroblasts. The attenuated virus was assigned the identification CVA-HFE. Its properties were characterized for the first time by Mayr and Munz[ 4 ] in the 371st passage.
