The verdict
Rohm holds 146 US patents across 34 technology areas, rank #2,664 of 50,000 tracked assignees.
Rohm And Haas Electronic Materials CMP Holdings, Inc. has been granted 146 US utility patents between 2015 and 2025, placing Rohm And Haas Electronic Materials CMP Holdings, Inc. at rank #2,664 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 claims per patent with primary concentration in B24B (MACHINES, DEVICES, OR PROCESSES FOR GRINDING OR POLISHING ; DRESSING OR CONDITIONING OF ABRADING SURFACES; FEEDING OF GRINDING, POLISHING, OR LAPPING AGENTS). As a US Corporation, Rohm And Haas Electronic Materials CMP Holdings, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Rohm sits between Joseph Voegele Ag (146 patents, rank #2,660) and SPIN Memory, Inc. (146 patents, rank #2,668) - the closest US assignees by grant volume. The composite Innovation Score of 46.7/100 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 65 grants, compared with 81 in the 2015–2019 window, a -20% 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. Rohm And Haas Electronic Materials CMP Holdings, Inc.'s 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rohm And Haas Electronic Materials CMP Holdings, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Rohm's 146 grants land it in the top 20% 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.
