Patented technology: As the name implies, it refers to the technology protected by patents within the validity period. According to the classification of patents in China's patent law, it mainly includes technologies protected by invention patents and utility model patents. Because the design patent protects the new design, not the technology, it should be called the design patent, not the patented technology. But generally speaking, patent technology in a broad sense includes invention patent, utility model patent and design patent.
Proprietary technology: refers to the sum of professional knowledge, operating experience and technology in producing a certain product. Refers to the advanced and practical technical secrets that have not been patented, including design drawings, formulas, data formulas, and the experience and knowledge of technicians.
