Trade Secrets & Corporate Espionage

Trade secrets are not registered anywhere
— which means the whole case is proving you protected them.

Unlike a patent or a trademark, a trade secret is not registered with any authority and carries no certificate proving it exists. Its legal protection depends entirely on the business actively treating the information as confidential — restricting who can access it, marking it clearly, requiring signed confidentiality undertakings, and being able to show all of that in court if the information ever leaks. Businesses that assume their sensitive data is automatically protected because it feels obviously valuable are often surprised to learn that, without evidence of these measures, a court may find there was no protectable trade secret at all. The evidentiary record of "reasonable protective measures" is frequently the entire case, decided before the question of misuse is even reached. A trade secrets lawyer in Greece will ask what protective steps were documented, because that is the limb courts test hardest.

The highest-risk moment for trade secret leakage is predictable: it is the point at which a key employee resigns, particularly to join a competitor or start a competing venture. In the days around a departure, access to shared drives, client lists, pricing models and product documentation is at its most exploitable, and the window to act — revoking credentials, imaging devices, securing signed acknowledgements — is short and closes fast. Businesses that treat the exit interview as an HR formality rather than a security control point are the ones that discover the leak months later, after the evidence trail has gone cold.

"An NDA on file is not a protection programme. We regularly see businesses with a signed confidentiality agreement and no access controls, no information classification and no exit protocol behind it — the document exists, but nothing enforces it." When an employee leaves with information, a trade secrets lawyer in Greece works to a very short evidential window.

When espionage is suspected — a former employee competing suspiciously fast, a competitor quoting terms they should not know, unusual access logs before a resignation — speed is what determines the outcome. Effective response means urgent evidence preservation before devices are wiped or reused, forensic imaging coordinated correctly so the evidence remains usable in court, and injunctive relief sought quickly enough to stop ongoing use of the information before the commercial damage compounds and becomes unrecoverable. We build the protective programme before an incident happens and run the response process when one does. If information has already left, treat it as urgent.

No registration
Trade secrets aren't registered — protection is proven, not presumed
There is no certificate of ownership. Whether information legally qualifies as a protected trade secret depends on the access controls, confidentiality agreements and classification practices the business can actually document.
Departing employees
The departing-employee moment is the highest-risk window
Resignations, especially to a competitor, are when confidential data is most likely to walk out the door — and when access revocation and device protocols matter most.
Response speed
Speed matters in espionage response
Evidence degrades and commercial damage compounds by the day. Forensic preservation and injunctive relief need to move in days, not weeks.
Programme, not paper
An NDA alone isn't a protection programme
A signed confidentiality agreement without access controls, classification and exit protocols behind it is a document, not a defence.

How We Work

A process built to prevent the leak, and to move fast when one happens anyway.

STEP 01
Risk Assessment & Programme Audit
We review what information actually needs protecting, what protective measures already exist, and where the gaps are — before an incident forces the question.
STEP 02
Protective Framework Design — or Urgent Response Triage
For preventive work: designing access controls, classification and confidentiality documentation. For an active incident: immediate triage to establish what happened and what needs to be preserved right now.
STEP 03
Investigation & Evidence Preservation
Coordinating forensic imaging and evidence collection so the record is both complete and usable in court, not compromised by a delayed or improvised response.
STEP 04
Enforcement — Injunctive Relief & Litigation
Seeking emergency court orders to stop ongoing misuse, and pursuing damages or other remedies where the evidence and the commercial reality justify it.

Frequently Asked Questions

Questions about trade secrets and corporate espionage.

What actually counts as a "trade secret" under Greek law, and how is it different from a patent?+

A patent is registered with an authority, examined and published; a trade secret is none of those things. It is simply information — a client list, a pricing model, a manufacturing process, source code — that has commercial value because it is not generally known, and that the business has taken active, documented steps to keep confidential. There is no certificate to point to. If a dispute arises, the business generally has to prove both that the information had genuine value from being secret and that it took reasonable protective measures — access restrictions, confidentiality agreements, marking, need-to-know limits — to keep it that way. Information a business has never treated as confidential in practice will struggle to be recognised as a protected trade secret at all.

A key employee just resigned to join a competitor — what should we do immediately?+

Move fast and move in order. Revoke system and data access as close to the resignation announcement as the business can manage, secure and — where appropriate — image the employee's devices and accounts before they are wiped or reissued, and review access logs for unusual download or transfer activity in the weeks before the resignation. Do not wait until the last working day to start this process. In parallel, get legal advice on whether any non-compete, non-solicitation or confidentiality clause in that employee's contract is actually enforceable, and whether the facts support an urgent injunction if there is evidence data has already left the building. The first 48 hours after a competitor-bound resignation are usually the most consequential.

Is an NDA enough to protect our confidential information?+

On its own, usually not. A signed NDA is evidence that the recipient was told the information was confidential, which matters, but it does not by itself demonstrate that the business treated the information as genuinely secret in practice. Courts and counterparties look at the whole picture — was access to the information actually restricted, was it marked or labelled, was there an internal policy governing who could see it and how it could be shared. A business with a signed NDA and no access controls or classification system behind it has a much weaker case than one that pairs the agreement with a real protective programme. The document should be the visible part of a system, not the whole system.

How quickly can we get an injunction to stop a former employee or competitor from using our information?+

Greek civil procedure provides for interim and emergency measures specifically designed for situations where waiting for a full trial would let the harm become irreversible — ongoing use or disclosure of a trade secret is a classic example. How quickly relief can actually be obtained depends heavily on the strength and completeness of the evidence presented at the outset, which is why evidence preservation has to happen in parallel with, not after, the decision to seek an injunction. Cases built on a documented protective programme and clear evidence of misuse move faster than cases where the underlying facts are still being pieced together. We prepare the application and the evidentiary record together, not sequentially.

What does a corporate espionage investigation actually involve?+

It typically starts with identifying what triggered the suspicion — a competitor's behaviour, an unusual access pattern, a tip from a colleague — and then moves quickly to preserving whatever evidence exists before it can be altered or lost: device images, access and download logs, email and file-transfer records. We coordinate directly with forensic investigators and IT specialists so that preservation is done to a standard that will hold up if the matter proceeds to litigation, rather than being handled informally by internal IT in a way that can compromise the evidence. In parallel, we assess what legal remedies the emerging facts support — a demand letter, an injunction application, a damages claim — so the investigation and the legal response develop together rather than one waiting on the other.
