February 2, 2023: European battery patent purposes proceed to rise in 2022 whereas the quantity granted continues to say no – suggesting a extra saturated panorama or bigger battery corporations making an attempt to -outclass others, based on a research revealed on January 30.
Evaluation by mental property specialists Mewburn Ellis reveals almost 4,000 European patent (EP) purposes revealed in 2020 adopted by almost 6,000 in 2022.
Nevertheless, whereas greater than 2,000 EPs had been issued in 2020 that quantity will drop to over 1,000 in 2022, based on ‘Battery Insights and IP Traits’ research.
The variety of European battery patents granted every year has been falling steadily since 2018 – and the autumn seems to be extra sustained and higher than the 2014-2016 fall in revealed purposes, the research mentioned.
Based on Mewburn Ellis accomplice and patent legal professional Callum McGuinn, growing saturation within the battery subject, which has made it more and more troublesome to get a patent software to grant, may very well be an element within the decline.
McGuinn mentioned it may be an indication of a change in technique for the large battery corporations towards submitting extra purposes to fend off opponents, a lot of that are unlikely to pursue a grant. , the research says.
Inside workload pressures on the European Patent Workplace may play an element within the development.
With the event of applied sciences, the research states that “a extra advanced battery panorama is creating with inadequate consideration for sustainable battery disposal and good exploitation of their round potential”.
The patent information reveals a low however gradual improvement of concerns in the direction of battery end-of-life. In 2010, solely 0.26% of lithium ion battery patent publications had been labeled as involving recycling utilizing the cooperative patent classification (CPC), which allocates particular codes to every expertise space. However there shall be a five-fold improve of 1.37% in 2020.
“The goal is obvious: the battery worth chain should turn into extra round,” the research says.
“Getting there’ll contain a mixture of efficient coverage, progressive recycling processes, pragmatic reuse of outdated batteries and considerate design.”
In the meantime, Mewburn Ellis accomplice and patent legal professional Sam Bailey says that “it’s possible that the battery ecosystem will proceed to be dominated by lithium ion and lead-based chemistries within the close to future.
“Regardless of their relative age, lead-based batteries are nonetheless utilized in many industries and supply some efficiency and software advantages over Li ion programs, and environmental elements, comparable to their comparatively simple and good recycling, which means they’ll possible stay a part of the battery panorama for the foreseeable future.”
