Patents

Right from its inception, the Trevi Group has distinguished itself for its innovation capacity in the field to which it belongs, by developing concrete solutions aiming at meeting actual operational needs. For this purpose and in order to protect the intellectual property of the inventions conceived, Soilmec has always promoted an intense patenting activity.

The first patent application submitted on behalf of Soilmec dates back to 1983; since then, 97 applications have been filed to protect the same number of inventions conceived by the company’s engineers. As of today, Soilmec holds patents granted or under concession for 76 of said inventions, while the patents of the remaining ones have been obtained but have now reached their natural expiry.
