The formula for calculating the intensity of patent cooperation is: the intensity of patent cooperation = the number of cooperative patents ÷ the total number of patents, in which the number of cooperative patents refers to the number of patents applied or authorized by two or more organizations (companies or research institutions) in a certain period; The total number of patents includes all patents independently applied or authorized by all these organizations.
The actual calculation method may also be more complicated, which may include other factors, such as patent type and application field.
