Patent law is a branch of industrial property law that is becoming increasingly important. Numerous disputes are likely to arise in this area (patent infringement action, patent cancellation action, employee inventions, etc.)
In our highly competitive society, in a context of internationalisation of the economy and dematerialisation of exchanges, patents have become a priority for any inventor wishing to protect his creation. Nevertheless, because it is a living law, in constant evolution, patent law is as complex as it is exciting. This is why we put so much energy and fervour into defending each of our cases. At Dhenne Avocats, our activity is precisely focused on the protection of your inventions. We defend and advise our clients in all patent law disputes.

The role of Dhenne Avocats
upstream advice
The first of our missions is to map best routes of actions to protect your innovations according to your specific needs. Indeed, there are many ways to protect inventions and a patent is only one of them. In some particular cases, alternatives shall be explored, including contractual protection of know-how, trade secret protection and utility certificate.
In many cases, it is appropriate to adopt a "360" strategy that will appeal to both secrecy (especially NDAs) and the various domains of intellectual property (patent law, trademark law, design law, and copyright law) in order to ensure optimal protection for your innovations.
Thus, for example, the source code of a software will be protected by copyright while its functions may be protected by patents. However, it may be in some cases more judicious to opt for an action in parasitism.
