Nomenclature Emerging Patent Domains

To identify emerging technological fields, nomenclatures from various sources are used: the EPO, INPI, Eurostat, WIPO and finally the OECD[1] which did a precise job of identifying IPC codes and produced a very detailed nomenclature on the environment. The following areas are identified:

TIC

* *Biotechnology

* *Nanotechnologies

**Environment: use of the IPC and the Cooperative Patent Classification (CPC)[2] . Codes Y02 concern the environment and climate and are divided into six main areas:

General environmental management

Water-related adaptation technologies

Climate change mitigation technologies related to power generation, transmission and distribution

Capture, storage, sequestration or disposal of greenhouse gases

Mitigation of climate change, transport technologies

Mitigation of climate change, building technologies

Smart city concepts, smart grids

Y02 codes are retrieved from the Patstat database

_ [2]_ _The CPC is an extension of the IPC and is jointly managed by the EPO and the USPTO It is divided into nine sections, A-H and Y, which are in turn subdivided into classes, subclasses, groups and subgroups. Created in 2013, the CPC has approximately 250,000 classification entries, making it a more accurate system.
