5 concrete cases of unfair competition in Montpellier
1. Client poaching
A former employee or service provider directly contacts your clients to offer them the same services, sometimes at more attractive rates. By taking advantage of the commercial relationship initiated under your brand, they appropriate a part of your portfolio without effort or legitimacy.
2. Use of confidential information
The exploitation of client files, strategic data, or internal technical processes constitutes a violation of trade secrets. This harms your competitive advantage and represents a legitimate ground for legal action.
3. Non-compliance with the non-compete clause
When an employee leaves the company, they are sometimes contractually bound by a non-compete clause. If this is ignored and a new competing activity is created in the same geographical area, you are entitled to take action.
4. Concerted poaching
A competing company may deliberately recruit several of your key employees to weaken your structure. This type of targeted and concerted recruitment constitutes an unfair strategy if it aims to directly harm you.
5. Brand imitation or parasitism
Copying your visual identity, content, or advertising materials can lead to confusion in the consumer’s mind. This form of parasitism aims to profit from your reputation without real marketing effort.
