Portfolio overview

Ningbo Futai Electric Limited has been granted 50 US utility patents between 2015 and 2025, placing Ningbo Futai Electric Limited at rank #6,678 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.3 claims per patent with primary concentration in F21V (FUNCTIONAL FEATURES OR DETAILS OF LIGHTING DEVICES OR SYSTEMS THEREOF; STRUCTURAL COMBINATIONS OF LIGHTING DEVICES WITH OTHER ARTICLES, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Ningbo Futai Electric Limited is one of the more focused assignees in the PatentsView dataset. By volume, Ningbo sits between Lamb Weston, Inc. (50 patents, rank #6,674) and Navajo Manufacturing Company, Inc. (50 patents, rank #6,682) - the closest US assignees by grant volume. The composite Innovation Score of 29.2/100 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 34 grants, compared with 16 in the 2015–2019 window, a +113% 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 Futai Electric Limited's 4.3 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 Ningbo Futai Electric Limited against peers pursuing similar technology classes.
