Portfolio overview

Sumitomo Chemical Company, Limited has been granted 1,758 US utility patents between 2015 and 2025, placing Sumitomo Chemical Company, Limited at rank #233 across all assignees tracked by PlainPatent. This portfolio spans 176 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Sumitomo Chemical Company, Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Sumitomo sits between Tencent America Llc (1,774 patents, rank #229) and Signify Holding B.v. (1,748 patents, rank #237) - the closest US assignees by grant volume. The composite Innovation Score of 61.4/100 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 802 grants, compared with 956 in the 2015–2019 window, a -16% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Sumitomo Chemical Company, Limited's 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Sumitomo Chemical Company, Limited against peers pursuing similar technology classes.
