As a Foreign Corporation, NINGBO RICHEN ELECTRICAL APPLIANCE CO., LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.2/100 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 11 grants, compared with 2 in the 2015–2019 window — a +450% 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. NINGBO RICHEN ELECTRICAL APPLIANCE CO., LTD's 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NINGBO RICHEN ELECTRICAL APPLIANCE CO., LTD against peers pursuing similar technology classes.
