Phoenix Control Systems, Inc., appeals the district court’s grant of a preliminary injunction against alleged copyright infringement and misappropriation of trade secrets. In addition to attacking the merits of the injunction, Phoenix Control argues that the district court erred in its use of a special master and in other evidentiary matters. We affirm.
FACTS AND PROCEEDINGS BELOW
Johnson Controls, Inc., is a Wisconsin corporation that designs and implements automated process control systems. Johnson developed a system of computer programs to control wastewater treatment plants. This product line is called the “JC-5000S.” Derivatives of this program are used in several locations, and the program is customized for each location. Johnson registered its copyright in the JC-5000S.
Phoenix Control Systems, Inc., is a California corporation, formed by John Schratz in late 1983. It is a competitor of Johnson. Schratz and other individuals now working for Phoenix Control are former employees of Johnson. Johnson sued Phoenix Control for copyright infringement, misappropriation of trade secrets, unfair competition, trade libel, and interference with contractual relations. The district court granted Johnson’s motion for a preliminary injunction, which prohibited Phoenix Controls from copying, distributing, preparing derivatives of, publishing, or representing that they have the ability to use Johnson’s computer software referred to as the JC-5000S.
STANDARD OF REVIEW; PRELIMINARY INJUNCTIONS
Our review of a preliminary injunction is limited. We will reverse the granting of a preliminary injunction only if the district court abused its discretion, or based its decision on an erroneous legal standard or clearly erroneous findings of fact. Dumas v. Gommerman,
Johnson, the party requesting the preliminary injunction, had to show either a likelihood of success on the merits and the possibility of irreparable injury, or that serious questions going to the merits were raised and the balance of hardships tips sharply in its favor. Dumas,
A. COPYRIGHT INFRINGEMENT
To establish a case of copyright infringement, Johnson must prove ownership of the copyright, and copying of an expression protected by its copyright. Frybarger v. International Business Machines Corp.,
1. Ownershiy and Originality
Phoenix Control argues that Johnson’s computer program was not original, and thus not protected by copyright. See 3 M. Nimmer & D. Nimmer, Nimmer on Coyyright § 13.01[A] (1988). The standard of originality required for a copyright is minimal. Krofft,
2. Extent of Coyyright Protection
The district court held that Phoenix Control could infringe Johnson’s copyright without copying the literal elements of the program, which include the source and object code. This holding is not an incorrect statement of the law. Computer software is subject to copyright protection. 17 U.S.C. § 101. A computer program is made up of several different components, including the source and object code,
Where an idea and the expression “merge,” or are “inseparable,” the expression is not given copyright protection. Herbert Rosenthal Jewelry Corp. v. Kalyakian,
Source and object code, the literal components of a program, are consistently held protected by a copyright on the program. See, e.g. CMS Software Design Sys., Inc. v. Info Designs, Inc.,
Here, the district court found that the structure, sequence and organization of the JC-5000S was expression, and thus subject to protection. The JC-5000S is a
3. Copying
Johnson must show that Phoenix Control copied its computer program in order to prevail in its infringement case. See, e.g., Frybarger,
To show that Phoenix Control’s program is substantially similar to the JC-5000S, Johnson must demonstrate substantial similarity in both ideas and expression. Frybarger,
B. USE OF THE SPECIAL MASTER; EVIDENTIARY ISSUES
Phoenix Control argues that the special master was actually a court appointed expert, and should have been subject to cross-examination under Rule 706 of the Federal Rules of Evidence. Phoenix Control, however, waived any objections it had to the appointment of a master by failing to raise the issue, or moving to have the reference revoked. Spaulding v. University of Washington,
Allowing the special master to consider materials submitted by Johnson under seal, to which Phoenix Control did not have access, was not improper procedure. Phoenix Control acquiesced, and even stipulated, that documentation would be submitted under seal. This is proper procedure where the parties are concerned that trade secrets may be revealed. Fed.R.Civ.P. 26(c); see also Henry Hope X-Ray Products, Inc. v. Marron Carrel, Inc., 674
Phoenix Control also claims that the court should have reviewed the final version of its software once it was completed. We review the exclusion of this evidence for an abuse of discretion, see Contempo Metal Furniture Co. v. East Texas Motor Freight Lines,
CONCLUSION
Johnson demonstrated a reasonable likelihood of success on its copyright infringement claim. Nonliteral components of computer software may be protected by copyright where they constitute expression, rather than ideas. Access to Johnson’s program was clear, and the record supports the finding of substantial similarity. The district court did not err in its application of law, nor were any of its factual findings clearly erroneous.
AFFIRMED.
