Opinion

MEMORANDUM OPINION AND ORDER

KENDALL, District Judge.

Now before the Court are DSC Communications Corporation’s Motion for a Preliminary Injunction and Supporting Memorandum and DGI’s Motion to Vacate the Seizure Order, for Return of Wrongfully Seized Property, and for Forfeiture of the Bond, and Brief in Support. Both parties filed their respective responses and replies to both motions. Having considered these filed materials, as well as the arguments of counsel and evidence adduced at the July 24 and July 25,1995 hearing, the Court hereby GRANTS in PART and DENIES in PART both the Motion for a Preliminary Injunction and the Motion to Vacate the Seizure Order.

Background

Plaintiff DSC Communications Corporation (“DSC”) asserts several claims against Defendant DGI Technologies, Inc. (“DGI”) which involve DGI’s alleged wrongful copying or misappropriation of various software, firmware, DSC manuals and schematic diagrams. DSC alleges copyright infringement, trade secret misappropriation, unfair competition and Lanham Act violations.

*1186 Earlier this year, on April 28th, DSC counsel and the U.S. Marshals executed an ex parte seizure order at DGI’s premises. The seizure order was granted based upon DSC’s allegations of copyright violations by DGI and DGI’s surreptitious downloading of DSC’s software at one of DSC’s customer sites.

DSC and DGI’s dispute centers around the network of microprocessors and cards that DSC and DGI manufacture in order to control particular tasks in digital switching systems common in the telecommunications industry. The subject of the instant motions is the most recent upgrade in the microprocessor family, the MP-8, and the DSC software necessary to allow the MP-8 to function.

The hearing focused on three separate issues which this Order will address in turn. The first issue is whether DGI’s “disassem-bly” and “reverse engineering” of the firmware from the DSC MP-8 card violated the Copyright Act, 17 U.S.C. § 106 and whether DGI should be enjoined from further disas-sembly and reverse engineering. The next issue is whether DGI’s visits to the customer site to download copies of the operating system software located at that site also constituted copyright infringement and that an injunction should issue to prohibit further similar action. The third and final issue, is whether all of the actions DGI took were in the course of research, study and reverse engineering. Therefore, DGI seeks denial of any injunctive relief against them and also seeks to vacate the original seizure order.

Findings of Fact on the Firmware Issue 1

DSC is a Delaware Corporation with its principal place of business in Plano, Texas. DSC designs, manufactures and markets digital switching, transmission, access and private network system products for the worldwide communications network.

DGI is a Texas Corporation with its principal place of business in Richardson. DGI produces and markets products which are compatible with DSC systems.

DSC and DGI manufacture a family of products designed to control and to facilitate certain tasks in the telecommunications industry. These products include digital switching systems, microprocessor cards and other hardware. The microprocessors are placed on circuit boards, referred to as cards. The cards are inserted into digital interface modules, commonly called shelves. Finally, the shelves are placed in digital trunk frames. This system allows DSC and DGI customers to perform telecommunications tasks and service the needs of both the long distance and local phone customers. The most recent upgrade in the cards is the MP-8.

MP-8s are available for sale on the open market. The cards may be purchased from DSC directly, from one of its customers or on the surplus or used market. Each MP-8 contains firmware imbedded on a computer chip located on the card itself. Firmware is software which is imbedded in the computer chip. Firmware cannot be modified by the user or owner of the card.

DGI purchased a number of MP-8 cards on the open market. DGI purchased the card to study in order to develop a microprocessor card which would be compatible with DSC digital trunk frames and operating software.

Jay Gentry is an independent contractor who works at DGI. Gentry’s primary function is to develop firmware for use in the DGI version of the MP-8. Gentry, in the course of developing DGI’s firmware, developed a disassembly program in order to disassemble or translate, into human readable form, the DSC firmware retrieved from the DSC MP-8 card. Disassembling a program consists of translating the firmware code, or instructions, from machine readable object code to human (at least computer programmer) readable form.

Gentry has disassembled a program named CPBOOT and the firmware located on the *1187 Programmable Read Only Memory (PROM) chip on the DSC MP-8. After the disassem-bly was complete, Gentry provided the disassembled code to another DGI engineer, John Sanders, who drafted a flowchart of the firmware. Gentry used this flowchart and the disassembled DSC code to begin drafting the DGI firmware. Gentry’s initial draft of the DGI firmware was prepared January 10, 1995. Gentry has continued to working on successive drafts throughout 1995 and continues to work on subsequent drafts of the firmware to this date.

The DSC firmware and the DGI firmware were compared by each party’s expert witness. Based upon the agreement of both experts, the Court finds that the DSC firmware and the DGI firmware are not substantially similar.

DGI disassembled DSC’s firmware for a commercial purpose. DGI wanted to discover the functionalities and ideas expressed in the DSC firmware, in order to create their own firmware for use on a compatible microprocessor.

Conclusions of Law on the Firmware Issue

To obtain injunctive relief, Plaintiff must satisfy four stringent criteria: (a) that they are substantially likely to succeed on the merits of their claims, (b) that the Court's failure to issue the injunction poses a substantial threat of irreparable injury, (c) that the threatened injury outweighs any damage that the injunction's issuance might cause to the opposing party, and (d) that the injunction's issuance will not undermine the public interest. Roho, Inc. v. Marquis, 902 F.2d 356, 358 (5th Cir.1990); Allied Mktg. Group, Inc. v. CDL Mktg., Inc., 878 F.2d 806, 809 (5th Cir.1989). All four of these elements are mixed questions of law and fact. Blue Bell Bio-Medical v. Cin-Bad, Inc., 864 F.2d 1253, 1256 (5th Cir.1989). Each of these factors must be considered to determine whether, on balance, they collectively favor granting the injunction.
