Digital Computer Controls
Data General Corp. v. Digital Computer Controls, Inc. (1971) represents a pivotal decision by the Delaware Court of Chancery, establishing that extensive confidential dissemination of trade secrets does not inherently result in the loss of their protected status. Data General Corporation provided design schematics alongside its Nova 1200 minicomputer, clearly labeling these materials as confidential and securing purchaser compliance through contractual confidentiality obligations. Digital Computer Controls acquired these schematics through a secondhand Nova 1200 and subsequently created the D-116, a minicomputer closely resembling the Nova 1200. Although Digital Computer Controls contended that Data General’s broad sharing of the drawings undermined secrecy, the court determined that Data General had effectively safeguarded its trade secrets and held Digital Computer Controls accountable for misappropriation.
This ruling has shaped trade secret safeguards within software industries, where analogous confidentiality is maintained via clickwrap agreements.
Facts
In 1970, Data General introduced the Nova 1200 minicomputer, which offered performance twice that of its predecessors. Customers were permitted to obtain detailed design documentation to aid in servicing and repairs, provided they signed confidentiality agreements and received documents distinctly marked as proprietary. In 1971, Digital Computer Controls purchased a used Nova 1200 and obtained the associated design drawings from the seller. Despite explicit prohibitions against unauthorized use, Digital Computer Controls replicated these drawings and manufactured the D-116 minicomputer, which the court deemed to be "substantially identical" to the Nova 1200.
Decision
Data General filed for a preliminary injunction to stop sales of the D-116, alleging misappropriation of trade secrets. Digital Computer Controls sought summary judgment on grounds that Data General failed to maintain sufficient secrecy. The court rejected summary judgment, ruling that adequacy of secrecy was a factual issue requiring trial consideration, and also denied preliminary injunctions to avoid prematurely granting full relief. This stance was affirmed by the Delaware Supreme Court in 1972.
By 1975, Data General pursued permanent injunctive relief along with damages. The court evaluated Data General’s protective efforts: confidentiality labels on each drawing; compulsory confidentiality agreements with purchasers; contracts with employees and suppliers; and limiting access strictly to Nova 1200 owners. These precautions were found adequate to preserve trade secret status despite broad distribution.
Although Data General’s design materials were not copyrighted due to restricted disclosure, Digital Computer Controls’ exploitation of these trade secrets to develop a rival product was unlawful. A permanent injunction was issued, with damage assessments deferred to a jury in Superior Court.
Impact
The court’s determination that extensive dissemination does not automatically destroy trade secret protection carries substantial consequences for software firms. Software products frequently require customers to access embedded trade secrets within the distributed goods. To protect such sensitive information, clickwrap and shrinkwrap licenses are widely utilized. While the defendant admitted reviewing the confidentiality terms on the design documents, legal questions persist regarding the enforceability of clickwrap agreements. Moreover, contemporary software and hardware distribution vastly exceeds the scale of the Nova 1200’s customer base—ranging from approximately 80 to 6,000 users—prompting debate about when widespread disclosure effectively places information into the public domain.
