Fabian Gaessler (Max Planck Institute for Innovation and Competition) & Dietmar Harhoff (Max Planck Institute for Innovation and Competition), “Patent Transfers in Europe – Data and Methodological Report”
We introduce a new dataset on patent transfers – the Max Planck Institute for Innovation and Competition Patent Transfers Data 2016 (MPIIC-PT2016). The dataset entails registered patent ownership information changes of patents granted (DE) or validated in Germany (EP) between 1981 and 2013. For each patent and patent application we have information on current and all prior right holders in terms of name, country and address, as well as the date of change. With Germany having the highest validation and renewal rate among all EPC member countries, our data capture a maximum of possible patent transfers of EP patents. With the help of dictionary- and rule-based methods, we classify all ownership information changes according to a newly developed taxonomy of patent transfers. As a result, the MPIIC-PT2016 dataset distinguishes patent transfers by the relational and spatial distance of the transacting parties and hereby allows a first time quantification of the activities in the market for patents in Europe.
