Portfolio overview

Adeka Corporation has been granted 265 US utility patents between 2015 and 2025, placing Adeka Corporation at rank #1,563 across all assignees tracked by PlainPatent. This portfolio spans 78 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, Adeka Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Adeka sits between Kyungpook National University Industry-academic Cooperation Foundation (266 patents, rank #1,559) and Wright Medical Technology, Inc. (265 patents, rank #1,567) - the closest US assignees by grant volume. The composite Innovation Score of 56.3/100 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 118 grants, compared with 147 in the 2015–2019 window, a -20% 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. Adeka Corporation's 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 78 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Adeka 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.
