abstract

Understanding the evolution of a technological field in the course of time is a key task in technology analysis. Analysts in research institutions as well as in companies need to know which topics are relevant for the respective technological field, which are the emerging topics, which traditional topics have been deepened in the course of time and which have been abandoned. For this purpose we suggest a patent lane analysis. Patent lanes can be seen as the deployment of patent clusters in the course of time. We use a method based on semantic similarities to develop patent lanes. A case study focuses on the application of carbon fibers in bicycle technology; it is used to demonstrate our method, i.e. to establish patent lanes in this case and characterize them by multiple use of a Tf idf measure. Despite some limitations, patent lanes enable deep insights into the development of patent-friendly technological fields.

7. Conclusions

In this paper we have introduced patent lanes, which we define as the deployment of patent clusters in the course of time. For this purpose we have developed a generic process consisting of five steps, and discussed six design decisions related to these steps. The field of carbon fibers in combination with bicycle technology was chosen to demonstrate the patent lane method, leading to insights into the evolution of the technological field over time.
