Data General Corp. v. Digital Computer Controls, Inc. (1971) addressed the Delaware Court of Chancery's determination that extensive confidential dissemination of trade secrets does not automatically eliminate their protected status. Data General Corporation supplied design documents alongside its Nova 1200 minicomputer, clearly marking these materials as confidential and requiring customers to enter into agreements limiting their use. After acquiring a secondhand Nova 1200, Digital Computer Controls obtained and duplicated these drawings to manufacture a closely resembling minicomputer, the D-116. Digital Computer Controls contended that Data General’s widespread sharing of the drawings nullified their trade secret protection. The court rejected this argument, concluding that Data General had taken adequate measures to safeguard its proprietary information and ruled that Digital Computer Controls infringed trade secret laws by misappropriating the confidential designs.
This ruling has had a lasting impact on trade secret enforcement in technology industries, especially relating to software safeguarded by clickwrap agreements.
Facts
In 1970, Data General introduced the Nova 1200 minicomputer, which operated at twice the speed of prior models. Customers were able to request comprehensive design documentation intended for maintenance and repair purposes; these documents were distinctly marked as confidential and accompanied by enforceable confidentiality agreements. In 1971, Digital Computer Controls purchased a used Nova 1200 and obtained the related design drawings from the seller, which explicitly forbade unauthorized manufacturing based on those materials. Utilizing these drawings, Digital Computer Controls created the D-116 minicomputer, which the court found to be "substantially identical" to the Nova 1200.
Decision
Data General filed for a preliminary injunction against Digital Computer Controls alleging trade secret misappropriation. Digital Computer Controls sought summary judgment on the basis that Data General failed to maintain sufficient secrecy over its designs. The court held that whether secrecy measures were adequate was a factual question requiring trial, thus denying summary judgment. It also refused to grant the preliminary injunction at that stage, reasoning that any injunction should be limited in duration only until competitors could reverse engineer the product—thereby capping Data General’s potential relief. This ruling was affirmed by the Delaware Supreme Court in 1972.
By 1975, Data General pursued a permanent injunction along with monetary damages for misappropriation. The court examined Data General’s protective efforts: confidentiality notices on each drawing, mandatory confidentiality agreements signed by all customers, contracts with employees and suppliers, and restricted access limited exclusively to purchasers of the Nova 1200. These safeguards were found sufficient to preserve trade secret protection despite distribution to multiple parties.
The court further clarified that although the drawings did not qualify for copyright protection due to their limited disclosure, their usage was nonetheless controlled under trade secret law. While Digital Computer Controls had legitimately obtained the documents, it unlawfully exploited them in developing the D-116. Consequently, a permanent injunction was issued in favor of Data General, with damages referred for jury determination in Superior Court.
Impact
The court's determination that extensive disclosure does not automatically eliminate trade secret protection carries important consequences for software with broad distribution. Since software often necessitates that users interact with embedded proprietary information, maintaining confidentiality is essential. To safeguard such sensitive data, clickwrap and shrinkwrap licenses are frequently utilized. Although the defendant admitted to reviewing the confidentiality terms on design documents, the legal enforceability of clickwrap agreements continues to face scrutiny. Additionally, contemporary software and hardware are distributed on a scale far surpassing that of the Nova 1200, which was supplied to between 80 and 6,000 clients, raising ongoing questions about the threshold at which widespread exposure constitutes public domain knowledge.
