Portfolio overview

Rohm And Haas Electronic Materials Llc has been granted 464 US utility patents between 2015 and 2025, placing Rohm And Haas Electronic Materials Llc at rank #953 across all assignees tracked by PlainPatent. This portfolio spans 75 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in G03F (PHOTOMECHANICAL PRODUCTION OF TEXTURED OR PATTERNED SURFACES, e.g. FOR PRINTING, FOR PROCESSING OF SEMICONDUCTOR DEVICES; MATERIALS THEREFOR; ORIGINALS THEREFOR; APPARATUS SPECIALLY ADAPTED THEREFOR;). As a US Corporation, Rohm And Haas Electronic Materials Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Rohm sits between Siemens Healthineers Ag (466 patents, rank #949) and Himax Technologies Limited (462 patents, rank #957) - the closest US assignees by grant volume. The composite Innovation Score of 56.2/100 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 120 grants, compared with 344 in the 2015–2019 window, a -65% 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 Llc's 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 75 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rohm And Haas Electronic Materials Llc against peers pursuing similar technology classes.
