Portfolio overview

Quanzhou Shenglv Trading Co., Ltd. has been granted 5 US utility patents between 2024 and 2025, placing Quanzhou Shenglv Trading Co., Ltd. at rank #49,909 across all assignees tracked by PlainPatent. This portfolio spans 0 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.0 claims per patent. As a Foreign Corporation, Quanzhou Shenglv Trading Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Quanzhou sits between Quaero Ltd. (5 patents, rank #49,905) and Questech Corporation (5 patents, rank #49,913) - the closest US assignees by grant volume. The composite Innovation Score of 20.1/100 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. Historical data spans 2024 through 2025, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Quanzhou Shenglv Trading Co., Ltd.'s 1.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 0 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Quanzhou Shenglv Trading Co., Ltd. against peers pursuing similar technology classes.
