Portfolio overview

C3 Corporation has been granted 9 US utility patents between 2015 and 2025, placing C3 Corporation at rank #28,319 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 41.1 claims per patent with primary concentration in B65B (MACHINES, APPARATUS OR DEVICES FOR, OR METHODS OF, PACKAGING ARTICLES OR MATERIALS; UNPACKING). As a US Corporation, C3 Corporation is one of the more focused assignees in the PatentsView dataset. By volume, C3 sits between Burlywood, Inc. (9 patents, rank #28,315) and Canadian Solar Manufacturing (changshu) Inc. (9 patents, rank #28,323) - the closest US assignees by grant volume. The composite Innovation Score of 46.2/100 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 5 grants, compared with 4 in the 2015–2019 window, a +25% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. C3 Corporation's 41.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark C3 Corporation against peers pursuing similar technology classes.

How to use this portfolio

C3's 9 grants land it in the top 21% 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 - C3 ranks #28,319 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B65B - see who else leads that technology area. B65B 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.
