Portfolio overview

SANY Heavy Industry Co., Ltd. has been granted 11 US utility patents between 2015 and 2018, placing SANY Heavy Industry Co., Ltd. at rank #25,112 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.0 claims per patent with primary concentration in B66C (CRANES; LOAD-ENGAGING ELEMENTS OR DEVICES FOR CRANES, CAPSTANS, WINCHES, OR TACKLES). As a Foreign Corporation, SANY Heavy Industry Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SANY sits between Samsung Heavy Industries Co., Ltd. (11 patents, rank #25,108) and Schottky LSI, Inc. (11 patents, rank #25,116) - the closest US assignees by grant volume. The composite Innovation Score of 30.7/100 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 0 grants, compared with 11 in the 2015–2019 window, a -100% 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. SANY Heavy Industry Co., Ltd.'s 14.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SANY Heavy Industry Co., Ltd. against peers pursuing similar technology classes.

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.
