Background
Malvern Panalytical and TA Instruments are competing makers of rheometers — sophisticated scientific instruments used to measure the flow and deformation properties of materials like polymers, gels, and biological fluids. Malvern alleged that TA Instruments improperly obtained and used Malvern’s confidential algorithms and software code for advanced rheological measurements — specifically, algorithms related to oscillatory shear measurements used to characterize viscoelastic materials. Malvern brought claims under the federal Defend Trade Secrets Act (DTSA) and copyright law.
TA Instruments argued that the claimed trade secrets were either (1) not actually secret, having been disclosed in patents or scientific publications, or (2) subject to copyright preemption because they were functional software components rather than protectable expression. The district court ruled on summary judgment motions addressing preemption and trade secret protection scope.
The Court’s Holding
The Federal Circuit affirmed in part and vacated in part, providing guidance on the boundaries between trade secret and copyright protection for scientific software. The court held that copyright law does not preempt state or federal trade secret claims for software algorithms that are maintained as confidential — the fact that software can be protected by copyright does not eliminate trade secret protection for confidential source code and algorithms not publicly distributed. Trade secret protection attaches to the information itself when maintained in confidence, regardless of copyright’s availability.
The court also addressed the scope of trade secret protection for scientific measurement algorithms: algorithms specifically derived from or directly disclosed in published patents or scientific literature cannot be protected as trade secrets because the information is no longer secret, but internal implementation details and specific parameter tuning that go beyond public disclosures may retain trade secret status.
Key Takeaways
- Copyright law does not preempt trade secret claims for confidential software code and algorithms — trade secret protection and copyright protection can coexist for software, with trade secret protecting the confidential information and copyright protecting the expressive elements of the code.
- Scientific software algorithms that have been disclosed in patents or published papers lose trade secret protection for the disclosed elements — but internal implementation details, specific parameter values, and proprietary tuning methods not publicly disclosed may retain trade secret status.
- Companies in scientific instruments and measurement technology should carefully track which aspects of their software and algorithms have been publicly disclosed (through patents, papers, or conference presentations) and which remain confidential — only the undisclosed elements can be protected as trade secrets.
- The DTSA provides a federal forum for trade secret claims involving scientific software in commercial litigation between competing instrument makers — providing access to federal courts and remedies including injunctions and exemplary damages for willful misappropriation.
Why It Matters
Malvern Panalytical v. TA Instruments addressed the intersection of trade secret and copyright law for scientific instruments — a commercially important sector where sophisticated measurement algorithms represent years of development investment and significant competitive advantage. The case illustrated the layered IP protection strategy available for scientific software: copyright for the expressive elements of code, patents for disclosed inventions, and trade secrets for the confidential know-how, algorithms, and implementation details not publicly disclosed.
The decision is relevant to a broad range of scientific instrument, medical device, and laboratory technology companies whose competitive advantage rests on proprietary software algorithms for data acquisition, signal processing, and measurement interpretation. Understanding the boundaries between what can be protected as a trade secret versus what has been disclosed (and thus can only be protected through patents or copyright) is essential for managing IP portfolios in research-intensive, publication-oriented scientific fields where the line between public knowledge and proprietary know-how can be difficult to draw.
