Background
Harold Bowers created computer-aided design (CAD) software templates, which he sold as a product called Designer’s Toolkit alongside Cadjet software. He packaged the product with a shrink-wrap license — a license printed inside the product packaging, the terms of which the purchaser could read and accept or reject only after opening the box. The license expressly prohibited reverse engineering of the software.
Baystate Technologies, a competing software company, purchased copies of Designer’s Toolkit and allegedly reverse engineered the software to incorporate Bowers’s design into Baystate’s own products. Bowers sued for copyright infringement, patent infringement, and breach of contract. A jury found for Bowers on all three claims, awarding him nearly $6 million total. Baystate appealed, arguing that the shrink-wrap license’s prohibition on reverse engineering was preempted by federal copyright law, which under 17 U.S.C. § 1201(f) expressly permits reverse engineering to achieve interoperability.
The case raised a fundamental question about the relationship between contract law and copyright law: can a private license agreement restrict activities that federal copyright law explicitly permits?
The Court’s Holding
The Federal Circuit, in an opinion by Judge Rader, held that the shrink-wrap license was enforceable and not preempted by federal copyright law. The court reasoned that federal copyright preemption under 17 U.S.C. § 301 applies only to rights that are “equivalent” to rights under copyright. A contractual right — the right to enforce a promise between parties — is qualitatively different from a copyright right: it requires an extra element (the contractual agreement) that pure copyright claims do not. Because contract law adds an element that copyright law lacks, contract claims are not equivalent to copyright claims and therefore are not preempted.
The court acknowledged that copyright law permits reverse engineering in some circumstances (for interoperability purposes, under § 1201(f)), but held that this statutory permission does not prohibit parties from contractually agreeing to more restrictive terms. Just as parties can contractually limit other behaviors that law permits, a licensee can agree not to reverse engineer as a condition of obtaining the software.
Judge Dyk dissented vigorously, arguing that allowing private contracts to override federal copyright policy undermined Congressional intent and created a mechanism by which software publishers could contract away rights that Congress had expressly granted to users.
Key Takeaways
- Shrink-wrap licenses prohibiting reverse engineering of software are enforceable as a matter of contract law and are not preempted by the Copyright Act.
- Copyright preemption under 17 U.S.C. § 301 does not apply to contract claims because contracts require the extra element of an agreement between parties.
- Software publishers can use license agreements to restrict activities (such as reverse engineering) that copyright law itself would otherwise permit.
- The decision created tension with the view that copyright law’s affirmative permissions cannot be contracted away by private parties.
- The dissent highlighted a fundamental unresolved question in IP law: the extent to which private contracts can override public copyright policies.
Why It Matters
Bowers v. Baystate was the Federal Circuit’s most significant copyright decision of the era, and it remains controversial in IP law scholarship. The case established that in the Federal Circuit, at least, mass-market software licenses can expand copyright holders’ practical control over their products beyond the limits Congress set in the Copyright Act. This had enormous practical implications for the software industry: end-user license agreements (EULAs) routinely prohibit reverse engineering, security research, interoperability testing, and competitive analysis, and Bowers gave those restrictions legal teeth.
The decision was criticized by academics and security researchers who argued it created a private law mechanism that effectively eliminated rights Congress had deliberately preserved for users. The tension between contract enforcement and copyright policy continues to shape debates about software licensing, open source, and digital rights. Judge Dyk’s dissent laid the intellectual groundwork for later arguments about the limits of click-through licenses, and the broader question of whether private ordering can supersede public IP law remains unresolved at the Supreme Court level.
