Patent law is a branch of industrial property law that is becoming increasingly important. Many disputes can arise in this area (patent infringement actions, patent revocation actions, employee inventions, etc.).
In our highly competitive society, with its globalized economy and dematerialized trade, patents have become a priority for any inventor wishing to protect their creation. Nevertheless, because it is a living, constantly evolving body of law, patent law is as complex as it is fascinating. That is why we put so much energy and passion into defending each of our cases.
At Dhenne Avocats, our activity is precisely focused on the protection of your inventions.
We advise and counsel foreign and domestic businesses in all patent law disputes.

The role of Dhenne Avocats
upstream advice
Our primary mission is to advise you on the best strategy for protecting your innovations. There are many ways to protect your intellectual creations. When it comes to inventions, patents are not the only option. In some cases, it may be wise to opt for contractual protection of know-how or a utility certificate.
In many cases, it is advisable to adopt a “360” strategy that combines secrecy (particularly NDAs) with the various areas of intellectual property (patent law, trademark law, design law, and copyright law) to ensure optimal protection for your innovations.
For example, the source code of a software program will be protected by copyright, while its functions may be protected by patents. However, in some cases it may be more appropriate to take action for parasitism.
