Portfolio overview

Tokyo ROPE MFG. Co., Ltd. has been granted 37 US utility patents between 2015 and 2023, placing Tokyo ROPE MFG. Co., Ltd. at rank #8,693 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.7 claims per patent with primary concentration in D07B (ROPES OR CABLES IN GENERAL). As a Foreign Corporation, Tokyo ROPE MFG. Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tokyo sits between TGW Logistics Gmbh (37 patents, rank #8,689) and Telect, Inc. (37 patents, rank #8,697) - the closest US assignees by grant volume. The composite Innovation Score of 40.1/100 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 15 grants, compared with 22 in the 2015–2019 window, a -32% 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. Tokyo ROPE MFG. Co., Ltd.'s 5.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tokyo ROPE MFG. 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.
