Portfolio overview

Eaton Intelligent Power Limited has been granted 2,308 US utility patents between 2018 and 2025, placing Eaton Intelligent Power Limited at rank #166 across all assignees tracked by PlainPatent. This portfolio spans 215 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.1 claims per patent with primary concentration in H01H (ELECTRIC SWITCHES; RELAYS; SELECTORS; EMERGENCY PROTECTIVE DEVICES). As a Foreign Corporation, Eaton Intelligent Power Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Eaton sits between Lenovo (singapore) Pte. Ltd. (2,375 patents, rank #162) and NTT Docomo, Inc. (2,283 patents, rank #170) - the closest US assignees by grant volume. The composite Innovation Score of 65.8/100 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 1,680 grants, compared with 628 in the 2015–2019 window, a +168% 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. Eaton Intelligent Power Limited's 16.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Eaton Intelligent Power Limited against peers pursuing similar technology classes.
