Portfolio overview

State Grid Corporation Of China has been granted 198 US utility patents between 2015 and 2025, placing State Grid Corporation Of China at rank #2,019 across all assignees tracked by PlainPatent. This portfolio spans 94 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 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, State Grid Corporation Of China is one of the broader-portfolio assignees in the PatentsView dataset. By volume, State sits between Ossur HF (198 patents, rank #2,015) and Oculus VR, Llc (197 patents, rank #2,023) - the closest US assignees by grant volume. The composite Innovation Score of 56.5/100 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 111 grants, compared with 87 in the 2015–2019 window, a +28% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. State Grid Corporation Of China's 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 94 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark State Grid Corporation Of China against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
