PLEASE NOTE: We are committed to aggressively protecting our intellectual property following the laws of the countries in which we operate


The patent and the DCD Project were made for six years, from 2013 to 2019. In order to be able to obtain the product, it was necessary to introduce equipment from various industries in the process of production. Until 2013 there was no possibility to get the final product because there was not such sophisticated and precise equipment on the world market. Only when the US company Nordson launched the fluid dispenser with high accuracy on the market, we continued with the realization of the patent and DCD Project. On this occasion, we would like to especially thank the following companies whose equipment we use: Nordson Corp. (USA), Carl Zeiss  AG (Germany), Narishige  Group (Japan), GRS (USA),  Indutherm GmbH  ( Germany ), WPI Inc. ( USA ), Coherent Rofin (Germany ).

A patent is a form of intellectual property and an exclusive right granted by a government to an inventor. A license gives its owner the right to exclude others from making, using, selling, and importing an invention. A patent holder has the right to decide who may - or may not - use the patent invention for the period in which the invention is protected. In other words, patent protection means that the invention cannot be commercially made, used, distributed, imported, or sold by others without the patent owner's consent.
