Portfolio overview

IHI Ionbond Ag. has been granted 6 US utility patents between 2016 and 2020, placing IHI Ionbond Ag. at rank #40,827 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a Foreign Corporation, IHI Ionbond Ag. is one of the more focused assignees in the PatentsView dataset. By volume, IHI sits between IGF Oncology, Llc (6 patents, rank #40,823) and IKS Co., Ltd. (6 patents, rank #40,831) - the closest US assignees by grant volume. The composite Innovation Score of 22.6/100 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 2 grants, compared with 4 in the 2015–2019 window, a -50% 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. IHI Ionbond Ag.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark IHI Ionbond Ag. 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.
