We produce documents with time stamps, for example by registering them with an attorney or sending a certified fax, so as to establish usage rights.

This type of document enables an individual or company to certify the authority of a product or method on a certain date, thus granting them the right to produce and market said product, even after a third party requests a patent or industrial model to protect the same thing.

Usage rights do not give the same level of protection as a patent or utility model and cannot be transferred, sold or waived, unless the entire company ceases to operate. They constitute a type of defence document, however cannot be used to prevent others from producing or marketing the product concerned.
