Portfolio overview
Certona Corporation has been granted 9 US utility patents between 2015 and 2020, placing Certona Corporation at rank #28,448 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.6 claims per patent with primary concentration in G06N (COMPUTING ARRANGEMENTS BASED ON SPECIFIC COMPUTATIONAL MODELS). As a US Corporation, Certona Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Certona sits between Cellutech AB (9 patents, rank #28,444) and Charles & Colvard, Ltd. (9 patents, rank #28,452) - the closest US assignees by grant volume. The composite Innovation Score of 27.4/100 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 2 grants, compared with 7 in the 2015–2019 window, a -71% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Certona Corporation's 20.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Certona Corporation against peers pursuing similar technology classes.

How to use this portfolio
Certona's 9 grants land it in the top 76% by Innovation Score, but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance - Certona ranks #28,448 of 50,000. Top 50 holders
- Most of this portfolio concentrates in G06N - see who else leads that technology area. G06N leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
