New Energy Battery Cabinet Testing Patent

Which technologies grew in relevance to battery patenting?

We find that several battery-related technologies and applications, such as energy storage systems, battery management systems, wireless power transmission, electric vehicle charging, and uncrewed aerial vehicles (i.e., drones), grew in relevance both in absolute terms and relative to general battery patenting activity.

Are lithium-ion batteries patentable?

To be very clear: This especially means that the lithium-ion battery category does not contain any patent families tagged as solid-state battery inventions. The fourth step’s purpose was to add patent data related to redox-flow and nickel–hydrogen batteries to the dataset.

Are all patents related to solid-state batteries tagged?

Please note that due to the considerable overlap of the concept of solid-state batteries with other technologies, especially lithium-ion batteries, all patent families that were classified as patents related to solid-state batteries were untagged in any other category in which they acquired tags through the process described here.

Why is battery patenting a global trend?

We find that global battery patenting activity grew significantly in the 2000–2019 period. This stylized fact means that the comparative advantages of secondary approaches (rechargeable, redeployable, reusable batteries) have been continuously on the rise driven by innovation, making a direct contribution to socio-technical circularity.
