Portfolio overview

Saginomiya Seisakusho, Inc. has been granted 99 US utility patents between 2015 and 2025, placing Saginomiya Seisakusho, Inc. at rank #3,689 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.9 claims per patent with primary concentration in H02N (ELECTRIC MACHINES NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Saginomiya Seisakusho, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Saginomiya sits between OVH (99 patents, rank #3,685) and Veeva Systems Inc. (99 patents, rank #3,693) - the closest US assignees by grant volume. The composite Innovation Score of 49.4/100 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 51 grants, compared with 48 in the 2015–2019 window, a +6% 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. Saginomiya Seisakusho, Inc.'s 7.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Saginomiya Seisakusho, Inc. against peers pursuing similar technology classes.
