Portfolio overview
SUMITOMO WIRING SYSTEMS, LTD. has been granted 3,190 US utility patents between 2015 and 2025, placing SUMITOMO WIRING SYSTEMS, LTD. at rank #116 across all assignees tracked by PlainPatent. This portfolio spans 152 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in H01R (ELECTRICALLY-CONDUCTIVE CONNECTIONS; STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS). As a Foreign Corporation, SUMITOMO WIRING SYSTEMS, LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 62.7/100 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 1,913 grants, compared with 1,277 in the 2015–2019 window — a +50% 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. SUMITOMO WIRING SYSTEMS, LTD.'s 7.8 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 WIRING SYSTEMS, LTD. against peers pursuing similar technology classes.
