Portfolio overview

TODA Kogyo Corp. has been granted 76 US utility patents between 2015 and 2025, placing TODA Kogyo Corp. at rank #4,650 across all assignees tracked by PlainPatent. This portfolio spans 44 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 claims per patent with primary concentration in C01P (INDEXING SCHEME RELATING TO STRUCTURAL AND PHYSICAL ASPECTS OF SOLID INORGANIC COMPOUNDS). As a Foreign Corporation, TODA Kogyo Corp. is one of the more focused assignees in the PatentsView dataset. By volume, TODA sits between Smart Wires Inc. (76 patents, rank #4,646) and Arthrosurface Incorporated (75 patents, rank #4,654) - the closest US assignees by grant volume. The composite Innovation Score of 47.2/100 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 24 grants, compared with 52 in the 2015–2019 window, a -54% 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. TODA Kogyo Corp.'s 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 44 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TODA Kogyo Corp. 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.
