Intellectual Properties

JECHO has the core patent technology to ensure the advanced technology of products and maintain its leading position in international and domestic industries.
JECHO has applied for more than 10 new invention patents in China, PCT, USA and Europe. Supported by core patent technologies, we have a number of platforms, including human antibody phage library, high-efficiency expression cell line screening, recombinant protein soluble expression in E. coli, and bispecific antibody expression preparation.
We will be utilizing R&D and production activities for customizing process route characterized by streamlined, energy-efficient and low-cost, as well as providing customer solutions.
Our technical team can quickly achieve the technology transfer and large-scale production of our own products, while solving various process problems during pilot scale-up production and industrial manufacture. The process scheme is continuously optimized with streamlined equipment, energy saving and environmental protection, and low cost. Especially in the purification process, JECHO provides the most reasonable technology project with patented technology and self-built platform as per actual needs.

JECHO's invention names "Bivalent Bispecific Antibody Hybrid Protein Expression and Preparation Methods" has been granted by the European Patent Office in 2019 (European patent No. 3418305).
