Origins, History

J. Isern Miralles founded J. ISERN PATENTES Y MARCAS with offices in Barcelona and Madrid in 1924. After his death, he was succeeded by his son J. Isern Cuyás. He realized that the firm was consolidated in these two cities and decided to include more of the geography of Spain, focusing his efforts on expansion of the company. Offices were opened in Alicante, Zaragoza, Valencia, Granada and Logroño. He travelled throughout the world and began international expansion of the company.
