What this shows Mitsubishi Electric Home Appliance Co., Ltd. stamps GRANTS-SMALL, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #14,140 of 50,000; Innovation Score 37.4/100 sits in the top 44% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Miba Frictec Gmbh (±0 grants).
Mitsubishi Electric Home Appliance Co., Ltd. has been granted 21 US utility patents between 2017 and 2023, placing Mitsubishi Electric Home Appliance Co., Ltd. at #14,140 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a Foreign Corporation, Mitsubishi Electric Home Appliance Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsubishi sits between Miba Frictec Gmbh (21 patents, rank #14,139) and Municipal Parking Services, Inc. (21 patents, rank #14,147) - the closest US assignees by grant volume. The composite Innovation Score of 37.4/100 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 18 grants, compared with 3 in the 2015–2019 window, a +500% 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. Mitsubishi Electric Home Appliance Co., Ltd.'s 13.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 21 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
