Biobased Polymer Monomers Patents: Who Holds the Claims
27.6% concentration at the top. The five leading assignees together hold 2,093 of the 7,593 records in scope — a field with a defined leadership tier rather than a flat crowd of filers. Annual filings rose from 200 in 2017 to a peak of 319 in 2022, then eased to 246 by 2024 — a -12% move from 2021's 281, the last span the data can support as a complete comparison. 2025 and 2026 figures (down to 24 for the partial latest year) are still filling in under the usual publication lag and should not be read as a genuine falloff yet.

Common questions on the biobased polymer monomer patent field
Who are the leading patent holders in biobased polymer monomers?
The assignee ranking covers 100 companies, with the leading assignee holding 486 records against a total of 7,593 records in scope. The top 5 combined hold 2,093 records (27.6% of the total), and the top 10 extend that to 3,085 records (40.6%), which means a defined leadership tier exists but the majority of records still sit with a long tail of smaller filers. Reviewing both the leaders and that tail matters, because white space often sits just outside the leaders' core claims rather than in the tail itself.
Is filing activity in biobased polymer monomers growing or slowing?
Annual filings rose from 200 in 2017 to a peak of 319 in 2022, then eased to 246 by 2024, a -12% move from 2021's 281. That is the most recent span the data supports as a genuine comparison; figures for 2025 and 2026 are still partial because publication typically lags filing by about 18 months, so it would be premature to call the field in decline based on the very latest years alone. The safest reading is a field that has passed its 2022 filing peak and is settling to a somewhat lower but still active pace.
What does US7557224B2 actually block for someone developing PLA recycling technology?
US7557224B2 covers a specific method: thermally decomposing a mixture of polylactic acid or a derivative with aluminum hydroxide, at a temperature between the PLA's melting point and 320°C, to recover lactide with high optical purity. It blocks that particular depolymerization route and reagent combination for chemical recycling of PLA, not PLA synthesis or use in general. Anyone designing a recycling process should check whether their catalyst system and temperature window fall outside this specific claimed combination before assuming freedom to operate.
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 Biobased Polymer Monomers covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
