Biomass-Derived Carbon Patent Snapshot 2026
The biomass-derived carbon supply space is a small, growth-stage field dominated by academic and research institutions, with India as the primary filing jurisdiction. Activity is dispersed across many single-record applicants, with no single commercial incumbent holding a commanding position.
Academic institutions lead a fragmented, early-stage field
The top-ranked applicants — Hrushikesh Premchandra Lokhande, the Board of Regents of the University of Texas System, King Fahd University of Petroleum and Minerals, and SRM Institute of Science and Technology (Ramapuram Campus) — each hold 2 patent records, placing them in a tied first position. The top five filers collectively account for 31% of the combined total among the ranked applicants visible in this query, signalling moderate concentration at the very top within an otherwise highly fragmented field.
Beyond the leading quartet, every other ranked applicant holds a single patent record. This flat distribution indicates no entrenched incumbent and reflects a field still in early knowledge formation, where individual researchers and small academic groups are the primary IP generators.

The dominance of universities and research institutes — rather than industrial corporations — suggests that commercialisation pathways remain open and that technology transfer or licensing from academic IP holders could be a viable entry strategy for industrial players.
Filing counts for the most recent 18–24 months are systematically understated due to publication lag; the apparent activity levels for 2025 and 2026 should be treated as lower bounds. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity is rising and heavily weighted toward energy storage applications
Two charts frame the field’s trajectory: annual filing volume since 2017 and the distribution of technology classes across the corpus.
Annual filing trend
Annual filings have grown 67% in the recent window, consistent with a Growth life-cycle stage. Volume was minimal from 2017 through 2023, then accelerated sharply, with 2024 and 2025 recording the highest single-year totals to date. The 2025 and 2026 bars are understated due to publication lag and should not be read as a plateau.

H01G (Capacitors) is the visible IPC class, reflecting the field’s primary application in supercapacitor electrode materials derived from biomass carbon. C01B (Non-metallic elements and inorganic compounds) is the second-largest class, covering carbon synthesis chemistry. Nanotechnology (B82Y), medicinal preparations (A61K), and catalysis (B01J) each appear as smaller but distinct sub-themes, indicating that the technology is being explored across multiple end-use domains beyond energy storage.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
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.
King Fahd University of Petroleum and Minerals
King Fahd University of Petroleum and Minerals holds 2 patent records and is a new entrant in the recent period. Its filing emphasis is concentrated in H01G 11 (supercapacitor-type capacitors), indicating a focused research programme on biomass-derived carbon as an electrode material for energy storage applications.
patent records: 2Board of Regents, The University of Texas System
The University of Texas System Board of Regents also holds 2 patent records. Its technology emphasis spans H01G 11 (capacitors), B82Y 40 (nanotechnology applications), and D04H 1 (nonwovens and felts), suggesting a broader materials engineering approach that extends biomass-derived carbon into textile-based or fibrous electrode architectures.
patent records: 2Frequently asked questions
The corpus covers 20 patent families in scope. This is a small field by patent-landscape standards, consistent with its early Growth life-cycle stage.
India leads with 13 patent records, followed by the United States with 4 and China with 3. Indian academic and research institutions account for the large majority of activity.
Four applicants are tied at the top with 2 patent records each: Hrushikesh Premchandra Lokhande, the Board of Regents of the University of Texas System, King Fahd University of Petroleum and Minerals, and SRM Institute of Science and Technology (Ramapuram Campus). All are academic or research entities.
Supercapacitor electrode materials (IPC class H01G) is the visible application, accounting for 14 of the patent records. Carbon synthesis chemistry (C01B) is the second-largest class with 7 records.
The field is in a Growth stage, with annual filings rising and a 67% increase recorded in the recent filing window. Activity was very low before 2024 and has accelerated since. Recent years are understated due to publication lag.
Only one co-filing collaboration is recorded in the corpus: a joint application between the Defence Research and Development Organisation (DRDO) and IIT Guwahati. Inter-institutional and industry–academia co-filing is otherwise absent from the evidence.
