Portfolio overview

TAIZHOU DAJIANG IND. CO. LTD. has been granted 20 US utility patents between 2017 and 2025, placing TAIZHOU DAJIANG IND. CO. LTD. at rank #14,972 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in B25C (HAND-HELD NAILING OR STAPLING TOOLS; MANUALLY OPERATED PORTABLE STAPLING TOOLS). As a Foreign Corporation, TAIZHOU DAJIANG IND. CO. LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.8/100 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 7 grants, compared with 13 in the 2015–2019 window — a -46% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 DAJIANG IND. CO. LTD.'s 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TAIZHOU DAJIANG IND. CO. LTD. against peers pursuing similar technology classes.
