dreyfus-le-cabinetNowadays, it seems that intellectual property rights are not just an option available to companies, but an actual necessity. This does not surprise us!

No longer confined to luxury products, counterfeiting now extends to all business sectors. Every day, consumers are deceived by the poor quality products which are potentially dangerous to their health and safety.

With the continual development of new technologies, protection of one’s rights on the Internet has become indispensable.

Our purpose is to support you with all the flexibility and reactivity that our structure allows, while offering you the most up-to-date skill-sets, especially regarding international issues in the field of new technologies.

We wish to give you a simple understanding of what has become very complex. To ensure that the investment you make every day in your company’s trademarks and domain names remains profitable.
