Li-Ion Battery Testing Patent Snapshot 2026
The current indexed corpus for Li-Ion Battery Testing contains a single patent family, filed in 2025 and assigned to Ola Electric Mobility Ltd — indicating either a very narrow search scope or a nascent, largely uncharted filing space. Meaningful concentration and trend analysis awaits a broader corpus; the evidence presented here reflects what is currently indexed.
Ola Electric Mobility holds the sole indexed position
With one patent family in scope, Ola Electric Mobility Ltd ranks as the only filer in the current indexed corpus for Li-Ion Battery Testing, covering the intersection of coating and surface deposition (C23C) and battery cell technology (H01M).
Concentration is, by definition, absolute at this corpus size: the top-ranked filer accounts for the entirety of the ranked applicants visible in this query’ combined total, though the corpus itself is too small to draw structural conclusions about competitive intensity.

Ola Electric Mobility’s presence in this space — spanning both electrode-related and surface-coating sub-classes — suggests an integrated approach to cell engineering rather than a narrowly scoped testing methodology patent.
The single family was published in 2025; given standard publication lag of 18–24 months, additional related filings from 2024–2025 may not yet appear in the index. The current evidence should be treated as a minimum bound, not a complete picture.
A single 2025 filing marks the corpus; technology spans coatings and cell chemistry
The filing trend chart shows no activity from 2017 through 2024 and one family appearing in 2025, with 2026 showing zero — consistent with publication lag rather than a true cessation. The technology composition chart reflects two equally weighted IPC branches tied to that single family.
Annual filing trend
Filing activity is flat at zero from 2017 to 2024, with one family recorded in 2025. The absence of 2026 entries is expected given publication lag and should not be read as a trend reversal. No multi-year growth trajectory can be established from this corpus.

The indexed family spans two IPC branches in equal measure: C23C (coating and surface deposition) and H01M (batteries, cells, and fuel cells). This pairing suggests the filing addresses surface-engineering aspects of cell construction, such as electrode coating, within the broader battery-testing context.

A method for electrolyte filling and lithium-ion b…
The present disclosure provides a method for electrolyte filling for a lithium-ion battery cell, the method comprising: (i) degassing the battery cell at a pressure in a range of 0 kPa to 5 kPa; (ii) applying a high pressure at a range of 20 kPa to 50 kPa to fill the electrolyte into the battery cell; (iii) applying a low vacuum step at a range of -40 kPa… (excerpt from the patent abstract)

Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Ola Electric Mobility Ltd
Ola Electric Mobility holds 1 patent family in the indexed corpus, filed in 2025. Its technology emphasis spans C23C (coating and surface deposition) and H01M subclasses covering battery cells and electrodes, indicating an interest in the materials and surface-engineering dimensions of cell testing. No prior-period filing data is available, so momentum cannot be assessed.
families: 1Evidence pending
No second-ranked filer appears in the current indexed corpus. A broader search across additional IPC classes, jurisdictions, and date ranges is required before a challenger ranking can be established.
families: N/AFrequently asked questions
The current indexed corpus contains 1 patent family. This is a minimum bound; additional families from 2024–2025 filings may not yet have cleared the standard 18–24 month publication lag.
Ola Electric Mobility Ltd is the sole indexed filer, holding 1 patent family filed in 2025 through the Indian patent office.
Two branches are represented in equal measure: C23C (coating and surface deposition) and H01M (batteries, cells, and fuel cells), both tied to the single indexed family.
India is the only jurisdiction with an indexed filing. Major battery IP offices — USPTO, EPO, CNIPA, and JPO — show no indexed families under the current search scope.
The lifecycle stage cannot be determined from the current single-family corpus. A broader search is needed before a reliable stage classification (nascent, growth, or mature) can be assigned.
G01R (electrical measurement and testing) and G01N (materials analysis and characterisation) are two technically adjacent IPC branches absent from the current indexed corpus. Their absence reflects current index scope; a dedicated search in those classes is recommended before treating either as a confirmed open space.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
