Lithium battery patent fees

Are lithium-ion batteries patentable?

Frequently, patent filings for lithium-ion batteries cover a novel component material (e.g., an electrolyte formulation) or novel combination of component materials (e.g., solid-state battery architecture).

Should you consider battery technology before filing a patent?

Considering certain key technical elements of battery technologies before pursuing a claim — or even before filing a patent — can help prepare patent holders and their legal teams to assert ownership of an intellectual property asset efficiently and effectively when it matters most.

What is a battery patent?

The claims in these types of patents typically list specific formulation requirements, including details about the individual components in their initial form (raw materials) or upon assembly of the battery (e.g., concentration of electrolyte salt).

Are lithium-ion batteries reversible?

But unlike most technologies, the initial components of a lithium-ion battery cell can change in complex, irreversible ways during electrode manufacturing and battery cell assembly, and even more so once used in a product.

Are alternative battery chemistries getting more patents?

Between 2012-2021, the number of patent families filed in CPC class H01M10/054,13which relates to alternative battery chemistries, has steadily increased. The trends follow those seen for redox flow and solid-state battery technology, with a steady growth in the number of patent families filed in this class.

Can sodium ion batteries replace lithium?

Although their charge densities tend to be lower than lithium-based batteries, sodium-ion batteries are well suited to use in static storage and low-cost electric vehicles, such as e-bikes, and may soon replace lithium as a preferred battery chemistry for these applications.
