Portfolio overview
Nchain Holdings Ltd has been granted 40 US utility patents between 2017 and 2023, placing Nchain Holdings Ltd at #8,081 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a Foreign Corporation, Nchain Holdings Ltd is one of the more focused assignees in the PatentsView dataset. By volume, nchain sits between Zepp, Inc. (40 patents, rank #8,147) and Asahi Yukizai Corporation (39 patents, rank #8,155) - the closest US assignees by grant volume. The composite Innovation Score of 47.7/100 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 38 grants, compared with 2 in the 2015–2019 window, a +1800% 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 Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Nchain Holdings Ltd's 20.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 5 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
