1. High-tech threshold: patents in the chemical field will involve highly complex scientific principles and technical details, and experiments and research work are needed in the process of realizing and verifying new inventions, which makes it difficult to apply for chemical patents and requires professional knowledge and technical ability in the chemical field.
2. Intellectual property protection is difficult: the research and development cycle in the chemical field is long and the risk is high. According to the information disclosed in the R&D plan, researchers will find more effective and economical ways to achieve the same technical goals. Intellectual property protection in the chemical field is also facing challenges such as complex technology, easy imitation and difficult supervision.
