Inscription Breveté SGDG on an Ariston

Breveté SGDG is the name of a patent as it was in France until 1968. The expression stands for “Breveté Sans Garantie Du Gouvernement” and translates as: “Patent without government guarantee” .

Many countries have maintained a system of registration after a simple formal examination for many years . They believed they were free from any liability. For example, in France, the law of 1844 provides that patents are issued “without prior examination, at the risk and risk of the applicant and with no guarantee of function, novelty and merit of the invention, including with regard to the precision or accuracy of description” .
