USPTO PatentsView assignee record - 498 granted patents across 140 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS).
The verdict
Eastman holds 498 US patents across 140 technology areas, rank #903 of 50,000 tracked assignees.
Eastman Chemical Company has been granted 498 US utility patents between 2015 and 2025, placing Eastman Chemical Company at rank #903 across all assignees tracked by PlainPatent. This portfolio spans 140 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.9 claims per patent with primary concentration in C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS). As a US Corporation, Eastman Chemical Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Eastman sits between United Parcel Service OF America, Inc. (500 patents, rank #899) and Citizen Watch Co., Ltd. (494 patents, rank #907) - the closest US assignees by grant volume. The composite Innovation Score of 63.7/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 237 grants, compared with 261 in the 2015–2019 window, a -9% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Eastman Chemical Company's 17.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Eastman Chemical Company against peers pursuing similar technology classes.

How to use this portfolio
Eastman's 498 grants land it in the top 2% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
