Portfolio overview

Sumitomo Heavy Industries Construction Cranes Co., Ltd. has been granted 24 US utility patents between 2020 and 2025, placing Sumitomo Heavy Industries Construction Cranes Co., Ltd. at rank #12,672 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.9 claims per patent with primary concentration in B66C (CRANES; LOAD-ENGAGING ELEMENTS OR DEVICES FOR CRANES, CAPSTANS, WINCHES, OR TACKLES). As a Foreign Corporation, Sumitomo Heavy Industries Construction Cranes Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sumitomo sits between Spire Global, Inc. (24 patents, rank #12,668) and System Ceramics S.p.a. (24 patents, rank #12,676) - the closest US assignees by grant volume. The composite Innovation Score of 45.0/100 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 2020 through 2025, with 24 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. Sumitomo Heavy Industries Construction Cranes Co., Ltd.'s 12.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sumitomo Heavy Industries Construction Cranes 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.
