The risks to be considered are as follows:
The risk of patent expiration. The invention patent right is 20 years, and the utility model patent right is 10 year;
In the process of patent implementation, especially when the patent is licensed, a license contract must be signed to bind the licensee;
Strengthen the monitoring of competitors' research and development of similar products;
Constantly strengthen its own research and development capabilities and build a "patent protection fence" for the same products and similar products.
Products with independent intellectual property rights, especially those with invention patents, should get high monopoly profits, otherwise there is no need for innovation.
