Portfolio overview
Tianjin Yunda Industry And Trade Co., Ltd, Inc. has been granted 11 US utility patents between 2018 and 2025, placing Tianjin Yunda Industry And Trade Co., Ltd, Inc. at rank #25,409 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in C02F (TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE). As a Foreign Corporation, Tianjin Yunda Industry And Trade Co., Ltd, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Tianjin sits between Threatstop, Inc. (11 patents, rank #25,405) and Tilera Corporation (11 patents, rank #25,413) - the closest US assignees by grant volume. The composite Innovation Score of 39.6/100 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 10 grants, compared with 1 in the 2015–2019 window, a +900% 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. Tianjin Yunda Industry And Trade Co., Ltd, Inc.'s 6.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tianjin Yunda Industry And Trade Co., Ltd, Inc. against peers pursuing similar technology classes.
