How to avoid patent infringement when pharmaceutical enterprises develop new drugs

At present, more and more attention has been paid to the disputes caused by drug intellectual property rights, and patent protection has become a bottleneck restricting the development of China's pharmaceutical industry. For a long time, the strength of drug research and development in China is relatively weak. Many so-called new drugs are actually innovated and developed on the basis of foreign new drug technology, and some even copy foreign technology completely. It is difficult to change the weakness of China's medicine field in a short time. Facing the present situation that foreign companies have applied for patents in China, Chinese pharmaceutical enterprises should seek key technologies that are not protected by patents and seek drug development through "shortcuts" while avoiding patent infringement. In order to avoid infringement, domestic pharmaceutical companies must first find out whether the new drug has been patented by others when developing new drugs.
