NMC Battery Recycling Patent Landscape 2026
NMC Battery Recycling Patent Landscape in 2026
The patent corpus for NMC battery recycling is extremely small and highly concentrated, with a single applicant, Ascend Elements, holding all indexed families. The field is in its earliest formation stage, signaling that the technical and IP space remains largely open to new entrants.
Ascend Elements holds every family in an embryonic field
Ascend Elements is the sole ranked applicant, accounting for all 2 patent families in scope. The top five filers’ share of the hundred largest filers stands at 100%, the maximum possible concentration ratio, reflecting a field that has not yet attracted a broad applicant base.
There is no meaningful tier gap to describe because there is currently only one active filer. Any second entrant would immediately become a challenger with a realistic prospect of parity.

Ascend Elements’ position as the sole IP holder grants it an uncontested claim on the earliest-priority NMC recycling patents in this corpus, but the small absolute count means that position is not yet a durable moat — the window for challengers to establish foundational IP remains open.
Only 2 patent families are indexed; filings from the most recent 18–24 months are subject to publication lag and may understate current activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity is nascent; metal extraction dominates the technology mix
Annual filing data and IPC class composition together reveal a field that produced its first indexed output only in 2023, with technology emphasis split between hydrometallurgical metal recovery and battery cell chemistry.
Annual filing trend
Indexed families first appeared in 2023 and 2024, with one family each year; earlier years show zero activity in this corpus. The 2025 and 2026 counts should be treated as incomplete due to typical 18–24 month publication lag — actual recent filing activity is likely higher than the chart reflects.

C22B (metal extraction and refining) and H01M (batteries, cells, and fuel cells) each appear across both families, indicating that Ascend Elements’ filings address both the upstream hydrometallurgical recovery process and the downstream battery material output. C01G (compounds of other metals) covers one family, pointing to cathode-precursor chemistry as a secondary theme.

Curing process for surface defects of cathode mate…
A curing process for cathode material alleviates surface defects on particles of the cathode material for improving battery performance. Heat treating a granular form of the cathode material in a flow of an oxygen-containing gas removes surface defects on the cathode material particles that have been mechanically deagglomerated. This results in significant… (excerpt from the patent abstract)

What the IP structure implies for R&D investment decisions
A corpus this small provides directional rather than definitive strategic signals; nonetheless, the technology distribution and sole-applicant status offer actionable framing for teams evaluating entry.
Embryonic field — life-cycle stage not yet classifiable
With only 2 patent families indexed and first filings appearing in 2023, the field lacks sufficient volume for a formal life-cycle stage assignment. This is consistent with an embryonic or pre-growth phase where foundational process patents are only beginning to be filed. Early movers can still define claim scope across core process steps.
Pre-growthMaximum concentration; no competitive pressure yet observed
A single applicant holds all indexed families, producing a concentration ratio of 100% among the top hundred filers. This is not evidence of market dominance in a mature field but rather of a field where IP activity has not yet drawn a second filer. The competitive landscape can shift rapidly with even one or two new entrants filing foundational claims.
MonopolarNo co-applicant activity recorded
Evidence pending — the collaboration dataset shows no co-filed families in this corpus. The absence of co-applicants suggests that current IP activity is being pursued as proprietary rather than through consortium or university-industry partnerships, which is common in very early-stage fields before standardization efforts begin.
Solo filingUS filing priority with PCT coverage extending global optionality
One family is filed at the United States Patent and Trademark Office and one through WIPO’s PCT route, providing Ascend Elements with both a US home-market anchor and the ability to enter national phase in key battery manufacturing jurisdictions. Teams evaluating entry should monitor whether national-phase entries surface in the EU, China, South Korea, or Japan, as these would signal commercial priority markets.

Ascend Elements: sole filer, focused on metal extraction and battery chemistry
With 2 patent families, Ascend Elements is both the leader and the only ranked applicant in this corpus. Its technology emphasis spans the full NMC recycling value chain from hydrometallurgical extraction to cathode-ready battery material.
Ascend Elements
Ascend Elements holds all 2 patent families in scope, with technology focus concentrated in C22B metal extraction and refining (specifically sub-classes C22B3 and C22B47) and H01M10 battery cell chemistry. Its applicant momentum is classified as a new entrant, consistent with first indexed filings appearing in 2023–2024. The dual US and PCT filing strategy suggests early-stage global rights preservation.
families: 2No challenger identified
No second applicant appears in the indexed corpus. Any organization filing NMC battery recycling patents in an adjacent process domain — cathode precursor synthesis, black mass pretreatment, or direct recycling — would enter immediately as the field’s second-ranked filer and a de facto challenger to Ascend Elements’ current IP position.

Under-served branches adjacent to the current filing activity
Given the minimal corpus size, the following observations reflect IPC branches that are either absent or represented by only a single family — areas where additional technical work could complement the existing metal-extraction and battery-chemistry filings.
C01G — Cathode precursor compound synthesis
C01G appears in only one of the two indexed families, suggesting that the chemical synthesis of NMC precursor compounds (nickel-manganese-cobalt hydroxides) from recycled metal solutions is a sparsely covered branch. This step sits between hydrometallurgical recovery and active cathode material production and represents a technically meaningful gap where process IP has plausible commercial value if recycled-precursor quality can be demonstrated equivalent to virgin material.
Search this in Eureka →Black mass pretreatment and separation processes
Neither the techComposition nor the whitespace data surface any families covering upstream mechanical or thermal pretreatment of spent NMC cells — shredding, calcination, and separation steps that produce black mass feed for hydrometallurgical recovery. This upstream processing stage is a technically necessary precursor to the C22B extraction steps already covered and represents an adjacent branch that is absent from the current indexed corpus.
