USPTO PatentsView assignee record - 9 granted patents across 6 technology areas, active 2023–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B33Y (ADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3-D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3-D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE ).
The verdict
Shenzhen holds 9 US patents across 6 technology areas, rank #30,032 of 50,000 tracked assignees.
Shenzhen Tuozhu Technology Co., Ltd. has been granted 9 US utility patents between 2023 and 2025, placing Shenzhen Tuozhu Technology Co., Ltd. at rank #30,032 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 claims per patent with primary concentration in B33Y (ADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3-D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3-D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE ). As a Foreign Corporation, Shenzhen Tuozhu Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Shenzhen Meidong Acoustics Co., Ltd. (9 patents, rank #30,028) and Shijiazhuang Yiling Pharmaceutical Co., Ltd. (9 patents, rank #30,036) - the closest US assignees by grant volume. The composite Innovation Score of 43.0/100 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 9 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. Shenzhen Tuozhu Technology Co., Ltd.'s 10.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen Tuozhu Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shenzhen's 9 grants land it in the top 29% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
