Intellectual Property

Patents

The intellectual properties, such as the patents or design rights of the core technologies newly developed, are indispensable for the stable growth of the corporate activities.
Ferric registers the new successful technologies as much as possible in order to make good proposals for the clients todevelop new products.
Following are some of them.

Thermal business patents
