4 Agent Professional Patent Analysis
With the increasingly fierce technical competition in the world, enterprises all over the world have carried out patent strategy research, the core of which is patent analysis, that is, analyzing, processing and combining a large number of fragmentary patent information in patent specifications and patent bulletins, and transforming these information into competitive intelligence with overall and predictive functions by using statistical methods and techniques, thus providing decision-making reference for the development of technologies, products and services of enterprises. Patent analysis is not only the premise for enterprises to compete for patents, but also provides useful information for enterprises to formulate technical strategies and evaluate competitors. Therefore, patent analysis is a unique and practical analysis method in enterprise strategy and competition analysis, and it is also one of the commonly used analysis methods in enterprise competitive intelligence.
First of all, patent data cannot fully represent the innovation activities in the whole field. This is because, on the one hand, not every patent has the value of commercial innovation, on the other hand, many enterprises choose to keep business secrets to protect their innovative technologies, which can not be found by pure patent analysis. The value of patent analysis has been confirmed by many examples of strategic application of enterprises, but the accuracy and superiority of its analysis cannot be overestimated. There are still some defects and deficiencies in the practical application of patent analysis.
