Portfolio overview

Krosakiharima Corporation has been granted 37 US utility patents between 2015 and 2025, placing Krosakiharima Corporation at rank #8,621 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in B22D (CASTING OF METALS; CASTING OF OTHER SUBSTANCES BY THE SAME PROCESSES OR DEVICES). As a Foreign Corporation, Krosakiharima Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Krosakiharima sits between Kaltenbach & Voigt Gmbh (37 patents, rank #8,617) and Khalifa University Of Science, Technology And Research (37 patents, rank #8,625) - the closest US assignees by grant volume. The composite Innovation Score of 37.0/100 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 19 grants, compared with 18 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. Krosakiharima Corporation's 9.4 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 Krosakiharima Corporation 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.
