Portfolio overview
Taizhou Xiaotanglang Infant And Child Products Co., Ltd. has been granted 8 US utility patents between 2023 and 2025, placing Taizhou Xiaotanglang Infant And Child Products Co., Ltd. at rank #33,595 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.5 claims per patent with primary concentration in A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES). As a Foreign Corporation, Taizhou Xiaotanglang Infant And Child Products Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Taizhou sits between Tactical Medical Solutions, Llc (8 patents, rank #33,591) and Tangodown, Inc. (8 patents, rank #33,599) - the closest US assignees by grant volume. The composite Innovation Score of 34.4/100 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 2023 through 2025, with 8 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. Taizhou Xiaotanglang Infant And Child Products Co., Ltd.'s 5.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Taizhou Xiaotanglang Infant And Child Products Co., Ltd. against peers pursuing similar technology classes.
