Portfolio overview

Daishinku Corporation has been granted 59 US utility patents between 2015 and 2025, placing Daishinku Corporation at rank #5,753 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in H03H (IMPEDANCE NETWORKS, e.g. RESONANT CIRCUITS; RESONATORS). As a Foreign Corporation, Daishinku Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Daishinku sits between Contitech Transportbandsysteme Gmbh (59 patents, rank #5,749) and Eva Automation, Inc. (59 patents, rank #5,757) - the closest US assignees by grant volume. The composite Innovation Score of 42.8/100 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 31 grants, compared with 28 in the 2015–2019 window, a +11% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Daishinku Corporation's 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Daishinku Corporation against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
