Ethylene Octene Copolymer Patents: Who Leads, Trends 2026
Ethylene Octene Copolymer Grade Patents: Filing Trends and Leading Assignees
A long tail, not a leader. The top 5 assignees hold 21.9% of the 64 records in scope and the top 10 hold 37.5% — no single company dominates octene-plastomer claim space. Filings rose from 2 in 2017 to a peak of 6 in 2019, the highest single year in the tracked window. No reliable growth rate can be computed from this window because fewer than four complete years remain once publication lag is accounted for, and 2026 is a partial year.

Common questions
Who are the leading patent holders in ethylene octene copolymer grades?
The assignee ranking for this scope covers 58 companies, and no single filer dominates: the leader holds 6 of the 64 records, falling to just 2 by both the fifth and tenth positions. The top 5 assignees combined hold 21.9% of all 64 records, and the top 10 hold 37.5%. This is a fragmented landscape with a long tail of single- or few-filing entrants rather than one or two companies controlling the core claim space.
What is the difference between an ethylene octene copolymer and a polyolefin plastomer?
In patent filings the two terms overlap heavily, which is why this search combined both. Ethylene octene copolymer describes the specific comonomer chemistry, while polyolefin plastomer grade is a broader commercial and formulation term that can include other comonomers. Most of the records in this scope claim density, crystallinity control or comonomer ratio as the mechanism, regardless of which term the filing uses.
Which countries see the most patent filing activity for these materials?
China receives by far the most filings in this scope, with 34 of the 64 records routed through its patent office, more than three times the next largest office, Japan, at 10. India and South Korea each account for 5, and the United States and the European Patent Office trail at 3 and 2 respectively. This distribution suggests filing strategy here is largely shaped by domestic manufacturing markets rather than broad multi-jurisdiction protection.
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 Ethylene Octene Copolymer Grades covering 2015–2026, data cut-off 2026-07-31.
