Opinion

REAVLEY, Circuit Judge:

Vault brought this copyright infringement action against Quaid seeking damages and preliminary and permanent injunctions. The district court denied Vault’s motion for a preliminary injunction, holding that Vault did not have a reasonable probability of success on the merits. Vault Corp. v. Quaid Software Ltd., 655 F.Supp. 750 (E.D.La.1987). By stipulation of the parties, this ruling was made final and judgment was entered accordingly. We affirm.

I

Vault produces computer diskettes under the registered trademark “PROLOK” which are designed to prevent the unauthorized duplication of programs placed on them by software computer companies, Vault’s customers. Floppy diskettes serve as a medium upon which computer companies place their software programs. To use a program, a purchaser loads the diskette into the disk drive of a computer, thereby allowing the computer to read the program into its memory. The purchaser can then remove the diskette from the disk drive and operate the program from the computer’s memory. This process is repeated each time a program is used.

The protective device placed on a PRO-LOK diskette by Vault is comprised of two parts: a “fingerprint” and a software program (“Vault’s program”). 1 The “fingerprint” is a small mark physically placed on the magnetic surface of each PROLOK diskette which contains certain information that cannot be altered or erased. Vault’s program is a set of instructions to the computer which interact with the “fingerprint” to prevent the computer from operating the program recorded on a PROLOK diskette (by one of Vault’s customers) unless the computer verifies that the original PROLOK diskette, as identified by the “fingerprint,” is in the computer’s disk drive. While a purchaser can copy a PRO-LOK protected program onto another diskette, the computer will not read the program into its memory from the copy unless the original PROLOK diskette is also in one of the computer’s disk drives. The fact that a fully functional copy of a program cannot be made from a PROLOK diskette prevents purchasers from buying *257 a single program and making unauthorized copies for distribution to others.

Vault produced PROLOK in three stages. The original commercial versions, designated as versions 1.01, 1.02, 1.03,1.04 and 1.06 (“version 1.0”) were produced in 1983. Vault then incorporated improvements into the system and produced version 1.07 in 1984. The third major revision occurred in August and September of 1985 and was designated as versions 2.0 and 2.01 (“version 2.0”). Each version of PRO-LOK has been copyrighted and Vault includes a license agreement with every PROLOK package that specifically prohibits the copying, modification, translation, decompilation or disassembly of Vault’s program. 2 Beginning with version 2.0 in September 1985, Vault’s license agreement contained a choice of law clause adopting Louisiana law. 3

Quaid’s product, a diskette called “Copy-Write,” contains a feature called “RAM-KEY” which unlocks the PROLOK protective device and facilitates the creation of a fully functional copy of a program placed on a PROLOK diskette. The process is performed simply by copying the contents of the PROLOK diskette onto the Copy-Write diskette which can then be used to run the software program without the original PROLOK diskette in a computer disk drive. RAMKEY interacts with Vault’s program to make it appear to the computer that the CopyWrite diskette contains the “fingerprint,” thereby making the computer function as if the original PRO-LOK diskette is in its disk drive. A copy of a program placed on a CopyWrite diskette can be used without the original, and an unlimited number of fully functional copies can be made in this manner from the program originally placed on the PROLOK diskette.

Quaid first developed RAMKEY in September 1983 in response to PROLOK version 1.0. In order to develop this version of RAMKEY, Quaid copied Vault’s program into the memory of its computer and analyzed the manner in which the program operated. When Vault developed version 1.07, Quaid adapted RAMKEY in 1984 to defeat this new version. The adapted version of RAMKEY contained a sequence of approximately 30 characters found in Vault’s program and was discontinued in July 1984. Quaid then developed the cur *258 rent version of RAMKEY which also operates to defeat PROLOK version 1.07, but does not contain the sequence of characters used in the discontinued version. Quaid has not yet modified RAMKEY to defeat PROLOK version 2.0, and has agreed not to modify RAMKEY pending the outcome of this suit. Robert McQuaid, the sole owner of Quaid, testified in his deposition that while a CopyWrite diskette can be used to duplicate programs placed on all diskettes, whether copy-protected or not, the only purpose served by RAMKEY is to facilitate . the duplication of programs placed on copy-protected diskettes. He also stated that without the RAMKEY feature, CopyWrite would have no commercial value.
