The verdict
Celanese holds 21 US patents across 37 technology areas, rank #13,903 of 50,000 tracked assignees.
Celanese Acetate Llc has been granted 21 US utility patents between 2015 and 2019, placing Celanese Acetate Llc at rank #13,903 across all assignees tracked by PlainPatent. This portfolio spans 37 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in A24D (CIGARS; CIGARETTES; TOBACCO SMOKE FILTERS; MOUTHPIECES FOR CIGARS OR CIGARETTES; MANUFACTURE OF TOBACCO SMOKE FILTERS OR MOUTHPIECES). As a US Corporation, Celanese Acetate Llc is one of the more focused assignees in the PatentsView dataset. By volume, Celanese sits between Butler Home Products (21 patents, rank #13,899) and Changchun Institute OF Optics, FINE Mechanics AND Physics, Chinese Academy OF Sciences (21 patents, rank #13,907) - the closest US assignees by grant volume. The composite Innovation Score of 42.2/100 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 0 grants, compared with 21 in the 2015–2019 window, a -100% 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. Celanese Acetate Llc's 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 37 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Celanese Acetate Llc against peers pursuing similar technology classes.

How to use this portfolio
Celanese's 21 grants land it in the top 31% 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.
