Portfolio overview
TABUCHI ELECTRIC CO., LTD. has been granted 17 US utility patents between 2017 and 2021, placing TABUCHI ELECTRIC CO., LTD. at rank #17,249 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.2 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, TABUCHI ELECTRIC CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 26.6/100 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 4 grants, compared with 13 in the 2015–2019 window, a -69% 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. TABUCHI ELECTRIC CO., LTD.'s 7.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TABUCHI ELECTRIC CO., LTD. against peers pursuing similar technology classes.
