Patents for inventions

A patent provides the inventor the exclusive right to the invention for a period of 20 years from the filing date of the application.


Whether it is to prepare, file and complete patent applications, to prepare patent infringement or validity opinions, to negotiate licenses and agreements or to get advice on the protection of your inventions and determine the best strategy to adopt, it is crucial to consult a patent agent.

At Brouillette, we have the expertise and experience to assist you in Canada, the United States, Europe, China and abroad from the simplest to the most complex issue.

Our professional team provides strategic advice in a wide range of industries. Our expertise includes:
