Portfolio overview

Nuvolta Technologies (hefei) Co., Ltd. has been granted 41 US utility patents between 2020 and 2025, placing Nuvolta Technologies (hefei) Co., Ltd. at #7,898 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.6 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, Nuvolta Technologies (hefei) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nuvolta sits between National University Corporation Ehime University (41 patents, rank #7,895) and Omega Ophthalmics Llc (41 patents, rank #7,903) - the closest US assignees by grant volume. The composite Innovation Score of 57.6/100 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. Historical data spans 2020 through 2025, with 41 total grants over that period. 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. Nuvolta Technologies (hefei) Co., Ltd.'s 17.6 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 16 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

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.
