Portfolio overview

C3 Nano, Inc. has been granted 29 US utility patents between 2015 and 2024, placing C3 Nano, Inc. at #10,566 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.3 claims per patent with primary concentration in H01B (CABLES; CONDUCTORS; INSULATORS; SELECTION OF MATERIALS FOR THEIR CONDUCTIVE, INSULATING OR DIELECTRIC PROPERTIES). As a US Corporation, C3 Nano, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, C3 sits between Bote, Llc (29 patents, rank #10,563) and Cbrite Inc. (29 patents, rank #10,571) - the closest US assignees by grant volume. The composite Innovation Score of 48.5/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 19 grants, compared with 10 in the 2015–2019 window, a +90% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. C3 Nano, Inc.'s 18.3 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 20 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
