The global patents dataset on the vehicle powertrains of ICEV, HEV, and BEV

Abstract

Patent bibliometrics data are the most reliable business performance metric for applied research and development activities when investigating the knowledge domains or the technological evolution of vehicle powertrain technologies in the automotive industry. Our paper describes a global patents dataset for the internal combustion engine vehicles (ICEV), hybrid electric vehicles (HEV) and battery electric vehicles (BEV) over 1985–2016. We extracted the patents granted in each powertrain field from Thomson Reuters' Derwent Innovations Index (DII). We applied a combined search strategy of international patent classifications (IPCs) and keywords as well as ‘patent families’ and ‘priority dates’ to construct our global patents dataset. This strategy returned a total of 78,732 patents, within which we identified 49,154 ICEV patents; 10,888 HEV patents; and 18,690 BEV patents. Our database includes numerous descriptive features of each patent such as title, abstract, claim, priority, application and publication dates, IPCs, assignees/applicants, inventors, and cited references. These data are associated with the research article ‘The evolution of dynamic interactions between the knowledge development of powertrain systems’ [1] . The full dataset, which is attached to this article, may be useful to both researchers and practitioners interested in investigating, modelling or forecasting the complexity and evolution of the technical and knowledge domains of the vehicle powertrains, across a variety of instruments such as social network analysis and regression models.

A data set of Japanese corporates’ green transformation technologies patents

“…1 Borgstedt et al (2017) proposed a search strategy using IPC-classes and keywords is introduced that reveals all relevant patents and clearly differentiated four vehicle powertrain technologies. And Mirzadeh Phirouzabadi et al (2020) introduced a database using a combined search strategy of keywords and IPC codes.…”

The dataset of Japanese patents and patents’ holding firms in green vehicle powertrains field

“…We search patents’ title and abstract acquired last section using IPC classification and keywords. Green patents’ IPC classifications are supplied by IPC GREEN INVENTORY, 4 keywords are referred to some former researches [2 , 6 , 7] . We also search patents’ title and abstract written in Japanese, the comparison table of keywords may be found on the final sheet of our dataset.…”

Classifying Invention Objectives of Electric Vehicle Chargers through Natural Language Processing and Machine Learning

“…Choi (2018) suggested that patenting activity can be a robust indicator of technology development trends [1]. Phirouzabadi et al (2020) also supported the notion that patent bibliometrics data can inform applied R&D activities in a knowledge domain such as the evolution of vehicle powertrain technologies [11].…”
