Portfolio overview

SHINKAWA LTD. has been granted 121 US utility patents between 2015 and 2025, placing SHINKAWA LTD. at rank #3,124 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.7 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, SHINKAWA LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.0/100 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. Between 2020 and 2025 the company received 86 grants, compared with 35 in the 2015–2019 window — a +146% 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. SHINKAWA LTD.'s 8.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SHINKAWA LTD. against peers pursuing similar technology classes.
