Portfolio overview

Yamato Scale Co., Ltd. has been granted 49 US utility patents between 2015 and 2025, placing Yamato Scale Co., Ltd. at rank #6,862 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in G01G (WEIGHING). As a Foreign Corporation, Yamato Scale Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Yamato sits between Walter Ag (49 patents, rank #6,858) and Artemis Intelligent Power Limited (48 patents, rank #6,866) - the closest US assignees by grant volume. The composite Innovation Score of 50.6/100 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 21 grants, compared with 28 in the 2015–2019 window, a -25% 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. Yamato Scale Co., Ltd.'s 6.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yamato Scale 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.
