For a vast number of businesses, the most valuable intellectual property is never registered in a patent database. It exists in internal systems, manufacturing methods, source code, experimental data, pricing structures, AI optimisation techniques, and operational knowledge. Increasingly in our data driven world, these assets are being protected not through the patent system, but through secrecy.
Trade secrets have long coexisted with patents, trade marks, and copyright. But in sectors shaped by rapid innovation, data-driven development, and commercially sensitive technologies, they are becoming a central part of IP strategy. For these organisations, the key question is no longer simply what can be patented, but what should remain confidential.
Trade secrets as part of modern IP strategy
The attraction of trade secrets is straightforward. Unlike patents, they do not require public disclosure, and they are not limited to a fixed term of protection. Provided confidentiality is properly maintained, protection can theoretically last indefinitely.
Well-known examples illustrate the point. The formula used by The Coca-Cola Company remains one of the most famous trade secrets in the world, protected through secrecy rather than by patents. Similarly, aspects of the operational methodologies used by Google derive value from controlled internal knowledge and continual refinement.
For many businesses, particularly those in AI and software development, the commercial value of innovation increasingly lies not in a single patentable invention, but in accumulated process knowledge: training methodologies, infrastructure design, deployment systems, optimisation techniques, and proprietary datasets.
Trade secrets can offer an attractive prospect for such businesses: preserving competitive advantage through confidentiality rather than the exclusivity provided by patents alone.
Patents still matter but strategy matters too
The growing importance of trade secrets in certain sectors does not reduce the importance of patents. In practice, the two are often complementary rather than competing rights. In fact, the protection provided by trade secrets is only there to stop the unlawful acquisition, use or disclosure of trade secrets which have been obtained for example through unauthorised access or via dishonest conduct. A trade secret cannot however be used to stop a competitor who has created a product or process independently.
Patents remain essential where:
- Innovations can be easily reverse engineered
- Businesses require enforceable exclusivity
- Licensing or investment depends on registered rights
- Technological disclosure itself creates strategic market value
For a significant number of companies, patents remain fundamental commercial assets. However, the decision to patent is also a decision to disclose. Once published, the underlying technical information in the patent application enters the public domain, even if the patent itself is never granted, later expires, is challenged, or is not commercially exploited.
That creates a strategic balancing exercise for businesses operating in fast-moving sectors.
Some innovations are best protected through patents. Others are more valuable if kept confidential. Almost all require a combination of both.
This is where intellectual property strategy becomes more than a filing exercise. The role of patent attorneys and IP advisers increasingly involves helping businesses assess:
- What should be patented vs. what should remain confidential
- How different rights interact commercially
- How protection can be sustained over time
In practice, effective IP protection is often less about maximising registrations and more about aligning legal protection with commercial objectives.
The operational challenge of secrecy
Trade secrets can be commercially powerful, but they are also fragile.
Unlike patents, they do not arise through registration. Protection depends on demonstrating that information is genuinely confidential, commercially valuable because it is secret, and subject to reasonable protective measures.
That means trade secret protection is as much an operational issue as a legal one.
Businesses increasingly need to consider:
- Employee access controls and internal information segmentation
- Robust confidentiality and employment agreements
- Advanced cybersecurity protections and data governance structures
- Supplier, vendor, and collaborator arrangements
- Clear procedures for managing and auditing sensitive technical knowledge
Disputes frequently expose weaknesses in those systems. In cases such as IBM v LzLabs, courts highlighted the importance of contractual and technical controls surrounding confidential systems and commercially sensitive information.
The challenge becomes even more acute in industries shaped by collaboration, outsourcing, remote working, cloud infrastructure, and increased employee mobility. Once confidential information enters the public domain, protection may be irreversibly compromised. For that reason, trade secret protection cannot usually be treated as an afterthought. It requires governance, planning, and ongoing management.
AI, regulation, and the transparency problem
Artificial intelligence has intensified many of these issues. Modern AI systems often derive value from combinations of data, model architecture, optimisation processes, and operational refinement that may be difficult to patent due to not fitting neatly within traditional patent frameworks. At the same time, businesses are becoming increasingly cautious about disclosing commercially sensitive methodologies in highly competitive markets, as would be required in the patent system.
Yet regulation is moving in the opposite direction. Across data protection and emerging AI governance frameworks, regulators are placing greater emphasis on transparency, accountability, and explainability.
This creates a growing tension between:
- Protecting proprietary, "black-box" systems to maintain a market edge
- Satisfying regulatory expectations around public disclosure, safety audits, and oversight
For businesses developing AI systems, the question is no longer simply whether intellectual property exists. It is how protection, confidentiality, compliance, and commercial strategy can coexist.
Rethinking IP protection in technology-driven industries
For data driven businesses, trade secrets should no longer simply be considered a residual or fallback form of intellectual property protection. Increasingly, they should form the core of a broader strategic approach to managing innovation, competitive advantage, and commercial risk.
For businesses operating in technology-driven sectors, the key question is often not whether patents or trade secrets are “better.” The more critical issue is determining which form of protection is most commercially effective in a particular context, and how different protections can work together dynamically.
That assessment is rarely purely legal. It requires a deep understanding of innovation lifecycles, market dynamics, regulatory obligations, employee mobility risks, technical disclosure, and long-term commercial objectives.
As innovation becomes increasingly data-driven and commercially collaborative, businesses are reassessing not only what they protect, but how they protect it. Effective IP strategy now depends on making informed, deliberate decisions about which innovations should be patented, which should remain confidential, and how those protections can be robustly maintained in practice.
For forward-thinking organisations, reviewing whether existing IP strategies perfectly balance patents, trade secrets, confidentiality, and operational governance is becoming a vital part of protecting long-term competitive advantage.
