Portfolio overview
Rohm and Haas Electronic Materials Korea Ltd. has been granted 143 US utility patents between 2015 and 2025, placing Rohm and Haas Electronic Materials Korea Ltd. at rank #2,713 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 claims per patent with primary concentration in H10K (ORGANIC ELECTRIC SOLID-STATE DEVICES). As a Foreign Corporation, Rohm and Haas Electronic Materials Korea Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 49.9/100 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 104 grants, compared with 39 in the 2015–2019 window — a +167% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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 Korea Ltd.'s 10.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rohm and Haas Electronic Materials Korea Ltd. against peers pursuing similar technology classes.
