Opinion

FINDINGS OF FACT AND CONCLUSIONS OF LAW

BEER, District Judge.

Plaintiff Engineering Dynamics, Inc. (“EDI”) filed suit against defendants Structural Software, Inc. (“SSI”) and S. Rao Guntur for copyright infringement, trade dress infringement, and unfair competition regarding computer software and accompanying manuals used by engineers to analyze structures. The matter was tried before the bench from March 7th to March 12th, 1991. The final post trial brief was filed in June 1991. After considering the post trial briefs and proposed findings of fact and conclusions of law submitted by the parties, the court makes the following findings and conclusions:

FINDINGS OF FACT

Background Information

(1)Plaintiff EDI is a Louisiana corporation with its principal place of business in Louisiana. It creates, leases and updates structural analysis computer software, in particular a suite of programs called SACS. SACS was developed for use on a mainframe computer, but is now also compatible for use on a personal computer. (Angehr testimony, p. 40). The company’s owners and officers are David Garland, Jim An-gehr, and John Fowler.

(2) Defendant SSI is a Texas corporation with its principal place of business in Texas. It, too, creates and markets structural software and its main product is Stru-CAD*3D (“StruCAD”) 1 . SSI is operated and 80% owned by S. Rao Guntur. Stru-CAD operates only on a personal computer. (Guntur testimony, p. 435).

(3) Both SACS III and StruCAD are computer programs designed to solve engineering problems incident to the analysis of structures and were created primarily for use by engineers designing offshore structures.

(4) During the late 1970s a company called Synercom, Inc., which marketed a program called STRAN, sued EDI for copyright infringement of its manuals and input formats. The court held that the input formats were “idea” rather than “expression,” and thus uncopyrightable. It also ruled that the manuals were protected and that EDI had infringed them. Synercom Technology, Inc. v. University Computing Co., 462 F.Supp. 1003 (N.D.Tex.1978) (“Synercom ”). Synercom and EDI subsequently entered into a stipulation or settlement agreement providing in part that a manual called SACS III, which was drafted by EDI to replace the infringing SACS II manual, did not violate Synercom’s copyrights. (Px 392).

(5) In about 1986, defendants here, Gun-tur and SSI, purchased a program called SAP IV. Defendants used SACS III User’s Guide, the Joint Can. Design II and Seas-tate User’s Manual to develop a new program from the SAP IV. The new program was compatible with personal computers. The user/engineer works with a personal computer in a process in which information is able to be put into the program via a number of screen displays. (Guntur testimony, p. 458-465).

*580 (6) In contrast, SACS initially operated on a mainframe computer to which user/engineers had access through data service centers. Some time after StruCAD came on the market, SACS released a structural analysis program, that could be used on a personal computer.

A. Copyright Infringement

(7) SACS has been on the market since about 1975. (Fowler testimony, p. 299; Garland testimony, p. 90). SSI put its software product, StruCAD, on the market around 1986. StruCAD made structural analysis accessible on a personal computer before SACS had that capability. (Guntur testimony, p. 445). Both programs are accompanied by manuals which are comprised of pictures, diagrams, text, charts, illustrative examples, and flowcharts.

(8) EDI claims defendants infringed several of its manuals in the development and marketing of StruCAD, namely: the SACS III Users Guide, SACS IV User’s Guide, Joint Can Design II, and Seastate User’s Manual (collectively referred to as “the SACS manuals,” “SACS III” or “SACS”). (Px 1, 2, 3, 4, 9, 245, 12, 14). EDI also claims that defendants infringed its copyright in the “user interface,” which is comprised mainly of the input and output reports.

(9) The manuals included notice of copyright on their covers (Angehr testimony, pp. 77-78, Px 9, Px 245, Px 12, Px 14). EDI’s contracts with users and data service centers contains provisions to protect EDI’s proprietary rights. (Garland testimony, pp. 149-152; Dx 20, Dx 21, Dx 22, Dx 24).

(10) EDI registered the manuals with the United States Copyright Office shortly pri- or to filing this suit, in February, 1989. (Px 1-3), except SACS IV which was registered in July, 1990 (Px 4). Joint Can Design II, SACS III User’s Guide, and Seastate User’s Manual are copyrighted for the “entire text,” and SACS IV is copyrighted for “new text.” Px 1-4.

(11) The copyright applications do not reveal the derivation of SACS III from SACS II, nor do they discuss the Synercom litigation.

(12) In part due to their common ancestry in Synercom’s STRAN computer program, the text and diagrams in the Stru-CAD manual are substantially similar to those in the SACS manual, to the point of being nearly identical. (Px 203-Px 210; Guntur testimony 431-2; 436-7). The more than coincidental similarity of the two manuals is further evidenced by the reproduction of engineering errors in the SACS manual and in the StruCAD manual. (Px 165, Garland testimony, pp. 171-2, 175).

(13) Some elements of SACS’s design derive from Synercom’s product STRAN. Synercom, 462 F.Supp. at 1012. However, EDI redesigned the SACS manual in such a way to be no longer infringing on STRAN. As a result of that redrafting, the SACS III Manual was reviewed by Synercom itself for infringement, and is thus a new, independent, and original work.

(14) The key difference between SACS and StruCAD is that StruCAD was first to introduce a structural analysis program to the offshore market which can be used on a personal computer.

B. Trade Dress

(15) The SACS manuals and user interface reflect a continuously evolving product; EDI has expended considerable time, energy, and financial resources on improving their product. The result has been a look and feel of SACS which some engineers recognize and associate with EDI.

(16) SACS and StruCAD have user interfaces which are substantially similar. In contrast, other computer programs in the relevant market, ASAS, DAMS, STRUDL, NASTRAN, ANSYS, SESAM, STAR-DYNE, OSCAR, SAP 81, and SPACE IV employ user interfaces different from SACS and StruCAD. (Px 44, Px 45, Px 41, Dx 37, Dx 38, Dx 40, Px 42, Px 43, Px 46).

(17) Given the relatively insular and sophisticated nature of the offshore engineering community (the apparent main users of SACS and StruCAD) they are not prone to confuse the two software products. (Fowler testimony, pp. 319-320).

*581 C. Unfair Trade Practices

(18) In 1989, defendants attempted to register with the Louisiana Secretary of State to use EDI’s corporate name for their own purposes. (Px 100, Px 101, Guntur testimony, 397-400).
