Dendrite Suppression Patent Landscape 2026
Dendrite Suppression Patent Landscape in 2026
LG Energy Solution leads a moderately concentrated field, holding the largest share among the top hundred filers, with Korean industry and North American universities forming the two dominant tiers. The field is still expanding on a multi-year basis—recent-window growth at 65% above the prior period—though annual volume has eased from its 2022 peak and publication lag understates the most recent years.
LG Energy Solution leads a field shaped by industry-academia collaboration
LG Energy Solution holds the top position among the hundred largest filers, followed closely by LG Chem and the Regents of the University of California, forming a first tier of commercial and academic applicants each pursuing broad battery-cell and electrolyte strategies.
The top five filers account for 32% of the combined output of the hundred largest filers, indicating moderate concentration—no single player dominates, and a deep mid-tier of universities and specialist startups sustains competitive pressure.

The leadership positions of LG Energy Solution and LG Chem together signal that advanced lithium-metal cell development is driving the bulk of industrial activity, while the prominence of the University of California and MIT in the top ten reflects a strong academic pipeline that industry routinely draws from through co-filing.
Patent publication typically lags filing by 18–24 months, so activity recorded for 2024–2026 understates true recent output; the corpus covers global filings in scope as indexed. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year expansion continues, overwhelmingly anchored in battery-cell technology
The annual filing trend reveals a field that grew sharply to a 2022 peak before settling at sustained elevated levels, while the technology composition chart shows how completely the H01M battery-cell class dominates the research agenda.
Annual filing trend
Filings climbed to a peak in 2022, moderated in 2023, then recovered toward 2024–2025 levels; the 2025–2026 bars are meaningfully understated by publication lag and should not be read as a decline. The three-year recent window sits 65% above the prior three-year window, confirming multi-year growth.
↗ Hover for values · click a bar to ask EurekaTechnology composition
H01M (batteries, cells and fuel cells) accounts for the overwhelming majority of classified records, confirming that dendrite suppression activity is almost entirely expressed through battery-cell engineering. Adjacent classes—C01B (non-metallic/inorganic compounds), H01G (capacitors), C23C (coating and surface deposition) and C08L (polymer compositions)—each represent small single-digit shares, pointing to secondary research threads in materials synthesis, surface engineering and polymer electrolytes.

What the competitive structure means for R&D investment
Moderate concentration, active industry-academia co-filing, and a dominant battery-cell focus together define the strategic context for new entrants and incumbents alike.
Growth stage—multi-year expansion with a past-2022 peak
The field is classified as Growth: the recent three-year filing window sits 65% above the prior three-year window, confirming continued expansion on a multi-year basis. Annual volume eased from its 2022 peak, but this partly reflects publication lag in the most recent data. Teams entering now face an active, competitive landscape rather than a nascent one.
Growth stageModerate concentration with a strong mid-tier
The top five filers hold 32% of the combined output of the hundred largest filers—concentrated enough that the leaders shape technical norms, but open enough for challengers. The mid-tier includes well-funded startups (Group14 Technologies, Lyten, SES Holding) and prestigious research universities, sustaining broad inventive diversity. Differentiated materials or electrolyte approaches can still carve out defensible positions.
Moderate HHILG Energy Solution–UC and LG Chem–KAIST are the field’s dominant co-filing axes
The most active co-filing pair is LG Energy Solution and the Regents of the University of California, with 28 jointly attributed records—by far the largest single collaboration in this corpus. LG Chem and Korea Advanced Institute of Science and Technology form the second axis with 11 records, followed by LG Energy Solution with KAIST at 7. Samsung SDI co-files with both Samsung Electronics and Georgia Tech Research Corporation. These pairings show that deep industry-university ties are a structural feature of the field, not an outlier.
Industry-academiaUS filings dominate; EPO and PCT provide secondary international reach
The United States leads all jurisdictions, followed by Europe (EPO) and WIPO (PCT). India ranks fourth, notably ahead of China and South Korea at the national filing level, suggesting active domestic patenting by Indian academic and government institutions. China’s low national count—despite CATL’s presence in the applicant list—may reflect a corpus scope weighted toward US and European prosecution.

Co-filing pairs, ranked by the number of jointly-filed patent families.
LG Energy Solution and LG Chem anchor the field; universities and startups fill the challenger tier
The top two applicants are both LG affiliates, together accounting for a substantial share of the first tier; the University of California and KAIST represent the strongest academic challengers, while Group14 Technologies stands out among startups.
LG Energy Solution
LG Energy Solution leads with 82 patent records, concentrated across battery-cell architecture (H01M 10 and H01M 4) and cell-component engineering (H01M 50). Its momentum is classified as a new entrant in the most recent tracking window, suggesting recent filing activity is still being indexed rather than reflecting a strategic pullback. The close co-filing relationship with the University of California (28 joint records) extends its technology reach into advanced electrolyte and anode research.
patent records: 82Group14 Technologies
Group14 Technologies holds 15 patent records with a momentum classification of new entrant in the recent window, suggesting it is building its portfolio rapidly from a specialist silicon-carbon anode materials base. Its technology focus spans H01M 4 (electrode materials), C01B 32 and C01B 33 (non-metallic and inorganic compounds), differentiating it sharply from the electrolyte-heavy approaches of the LG entities and placing it in the underserved inorganic-materials adjacent space.

Under-served branches adjacent to the H01M core
Several IPC classes adjacent to the dominant H01M battery-cell core carry low record counts relative to the field total, representing observations of relative sparsity that may warrant closer examination for teams with specific technical approaches.
C23C · Coating and surface deposition
With 14 records, coating and surface deposition sits well below the H01M core. Thin-film and atomic-layer deposition techniques are mechanistically relevant to dendrite suppression—protective coatings on lithium anodes or separator surfaces directly impede dendrite nucleation. The sparse count suggests that applicants are primarily classifying such work under H01M rather than C23C, leaving the coating-specific framing relatively open. Teams specializing in vapor-phase or physical deposition processes could stake out differentiated claims here.
Search this in Eureka →C08L / C08J · Polymer compositions and processing
Polymer electrolyte and separator engineering is a recognized route to dendrite suppression, yet C08L (polymer compositions, 11 records) and C08J (polymer processing, 10 records) together account for a small fraction of the corpus. Given that solid and gel polymer electrolytes are an active research direction—evidenced by top-cited work on gels and nanocomposites—the low patent count in these polymer classes may indicate an opportunity for applicants who can anchor claims in polymer chemistry rather than only in cell architecture.
