6 FAQs about [Analysis of patent applications for flow batteries]

Are national battery patent applications considered in IEA & EPO?

Given the IPF constraint deployed for this study and the IEA and EPO report , these solely nationally filed applications are not considered in either one. In fact, in the current study’s dataset, IPFs make up only 19.4% of all battery patent families.

Can a patent proxy predict the price of lithium-ion batteries?

Kittner et al. and Ziegler and Trancik employed the patent proxy in their efforts to model the forces driving the prices of lithium-ion batteries, and found that cumulative patent filings is the best predictor of real prices scaled by energy capacity.

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.

Why is Asia's battery patenting activity low?

Asia contributed approximately 60% to the global labor force in the 2000–2019 timeframe (Europe and North America contributed approximately 9% and 8%, respectively). This imbalance explains why Asia’s battery patenting activity is lower in the perspective of this representation.

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.

Where do battery patents come from?

The majority of battery patents are found to originate in Asia while high battery patent intensities are revealed in the performance of several Asian and European countries. Overall, a considerable increase in annual battery patenting activity is observed from 2000–2009 to 2010–2019.
