Hair Repair and Bond Building Patents: Leaders & White Space 2026
Hair Repair and Bond Building Patents: Who Leads and Where the Filing Has Gone Quiet
A single filer dominates the ranking. the leading assignee holds 557 records against 111 at fifth place and 32 at tenth, a steep drop-off rather than a gradual one. Annual filings ran from 107 records in 2017 down to 5 in the most recent (partial) year. The reliable comparison is 2021 to 2024: 85 records down to 34, a -60% change over three years. Treat 2025 and 2026 as undercounted rather than as evidence the field has stopped.

Common questions about this landscape
Who holds the most patents in hair repair and bond-building technology?
The assignee ranking in this dataset is led by a research institution with 557 records, well ahead of the fifth-placed filer at 111 and the tenth at 32. That gap is unusually steep, which suggests the leader’s portfolio covers broad underlying genetic-engineering or protein methods rather than narrow cosmetic formulations. Consumer-facing hair-care brands appear further down the ranking with smaller, more formulation-specific portfolios. Anyone doing freedom-to-operate work in this space should check the leader’s claims first, since its volume alone makes overlap likely.
Is patent filing in hair repair and bond-building technology growing or slowing?
Filings peaked in 2017 at 107 records and the reliable year-on-year comparison, 2021 to 2024, shows a -60% decline from 85 to 34. However, publication typically lags actual filing by around 18 months, so the very low counts shown for 2025 and 2026 in this dataset are undercounted rather than a confirmed drop-off. The honest read is that filing has cooled from its 2017 high through 2024, with the most recent two years still an open question.
What technology areas dominate hair repair and bond-building patent claims?
Medicinal preparations (IPC class A61K) appear in 59.1% of the 1,406 records in scope, cosmetics-use claims (A61Q) in 42.7%, and microorganism/genetic-engineering claims (C12N) in 41.7%. Because a single record can carry multiple IPC codes, these figures overlap substantially rather than summing to 100%. This overlap reflects a field where formulation science and underlying biotech methods are frequently claimed together in the same filing family.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Hair Repair and Bond Building covering 2015–2026, data cut-off 2026-07-31.
