What this shows Ningbo Rotor Electrical Appliances Co., Ltd. stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-NARROW, INNOV-THIN, CLAIMS-SPARSE, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #17,945 of 50,000; Innovation Score 35.9/100 sits in the top 48% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is New Mexico Tech University Research Park Corporation (±0 grants).
Ningbo Rotor Electrical Appliances Co., Ltd. has been granted 16 US utility patents between 2018 and 2025, placing Ningbo Rotor Electrical Appliances Co., Ltd. at #17,945 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.9 claims per patent with primary concentration in A47F (SPECIAL FURNITURE, FITTINGS, OR ACCESSORIES FOR SHOPS, STOREHOUSES, BARS, RESTAURANTS OR THE LIKE; PAYING COUNTERS). As a Foreign Corporation, Ningbo Rotor Electrical Appliances Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ningbo sits between New Mexico Tech University Research Park Corporation (16 patents, rank #17,948) and Ocean Rodeo Sports Inc. (16 patents, rank #17,956) - the closest US assignees by grant volume. The composite Innovation Score of 35.9/100 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 10 grants, compared with 1 in the 2015–2019 window, a +900% 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. Ningbo Rotor Electrical Appliances Co., Ltd.'s 1.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 2 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
