4 Essentials of Trade Secrets
Trade secrets are one of a number of tools – including patents, trademarks, designs and copyright widely – which protect ‘creations of the mind’. Companies, researchers, inventors and creators often hold economically valuable information. They often keep this secret to give them an advantage over their competitors.
We’ve developed this interactive guide with eminent academics and experts to share tips and deepen your understanding of trade secrets. Thanks to the following organisations for their valuable insights, engagement and support.

If a trade secret could be relatively easy to discover independently or through reverse engineering, patent protection could be a better bet. Usually the simpler the information the easier it is to reverse engineer. For instance, skilled programmers can often see how a product works and design something similar. But code is trickier (and sometimes impossible) to reverse engineer – so keeping it as a trade secret works well.

The case of ‘Compulife Software v. Newman’ shows what happens when data isn’t kept secret. Lifting information from public websites doesn’t count as stealing a trade secret. Compulife got rate tables from insurers and used them on its website to let visitors get free insurance quotes. Newman then just used that data to generate quotes on their own websites.

Make sure you protect and restrict access to trade secrets. That means storing trade secret information in locked cabinets or password-protecting electronic files. It also means monitoring activity around trade secrets, tracking when documents are opened or copied and telling employees about the measures (letting them know helps deter theft).

Employees should only have access to data actually utilised or needed for a transaction.
Measures to manage trade secret information: Store organisational information in structured and systematic documents (physical and electronic), separate confidential and non–confidential information, control access (both electronic and physical), have a disaster recovery plan, encrypt your files, use antivirus software for electronic storage systems.
Measures to control access by third parties and employees: Review employment contracts, run regular information security policy awareness training for employees, use NDAs with liability clauses, report trade secret breach incidents, run information security audits, declassify information when it’s no longer a trade secret, enforce your information security policy quickly when a breach happens, conduct and document employee joining and exit interviews.

There are plenty of practical contractual options to protect trade secrets. They mainly consist of NDAs, non-use agreements, licence and know-how agreements for commercially transferring or lawfully using technology. Employment or consultancy agreements can also feature non-compete clauses or technical security measures for preventing trade secrets being stolen.

A trade secret isn’t the same as having exclusive rights over the information.
If someone else develops the same information by their own means, they can use it freely. Trade secret owners can’t prevent competitors from developing the same solutions through reverse engineering. This means finding out a device, object or system’s technological principles by analysing its structure, function and operation – it’s entirely legal.

Misappropriation usually means a trade secret being improperly acquired by someone who had proper access to it (internal theft) or by outsiders (external theft). For example ex-employees passing the trade secrets of their old employer to a new employer, or using the trade secrets of their old employer in a new business or new job. The key question is whether or not someone with proper access to a trade secret had a duty of trust and confidence which they violated by using and/or disclosing it.

In principle, misappropriating a trade secret doesn’t have to be intentional or negligent. So a trade secret holder can still get an injunction against an infringer even if it’s not their fault. But damages claims do need proof that they knew or should have known they were doing it.

Trade secrets can be legally discovered through reverse engineering. So they’re often difficult to enforce compared to patents. And most trade secret laws only protect against someone who obtains information improperly or who are in specified relationships with a trade secret owner. Patents are different because they can be fully enforced against infringers, regardless of their intention.

Information can be disclosed ‘in seriatim’ (like onion layers being peeled back) – revealing the most valuable information only after lengthy discussion and negotiation and if recipients agree to be bound by a confidentiality agreement. This is how trade secrets can aid licensing transactions.

Trade secrets and IP are complementary ways of appropriating intangible assets, but trade secrets don’t grant exclusive rights. Trade secrets are often part of the creative process leading to innovation and IP rights. For example, before an inventor patents something, they keep it secret to guard its novelty. So trade secrets are at the origin of patents (new inventions), copyright (new novels or songs), trademarks (new branded products), and designs (new product model designs).

Deciding how to protect a technical improvement depends on whether it’s easily copyable. If it is, it’s best to protect it with IP rights. If not, and it’s unlikely someone else would come up with the same thing, then keeping it as a trade secret usually raises a good enough barrier for competitors.

It’s important to guard trade secrets well during early development stages to protect information that gives competitive advantage. In a development phase, a company typically decides whether an idea is commercial and whether it might need something like a patent. Patents are sometimes better for maintaining a lead time on confidential information.

Trade secrets as property rights are licensable, so you can include them in licensing agreements alongside registered IP rights. A well-written licensing agreement should stipulate separate royalties for each form of right. This makes sure that if one IP right becomes invalid, another might keep providing income. Trade secrets can also be assigned or sold. So they can improve a new business’s prospects – crucial for spin-offs or start-ups.
