of 50,000 tracked assignees
USPTO PatentsView assignee record - 40 granted patents across 39 technology areas, recorded in grant years 2022–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL).
The verdict
According to USPTO PatentsView, Guangdong ranks #8,038 of 50,000 tracked US assignees by granted-patent volume, with 40 patents across 39 technology areas.
Guangdong Midea White Home Appliance Technology Innovation Center Co., Ltd. has been granted 40 US utility patents between 2022 and 2025, placing Guangdong Midea White Home Appliance Technology Innovation Center Co., Ltd. at #8,038 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 39 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.2 claims per patent with primary concentration in A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL). As a Foreign Corporation, Guangdong Midea White Home Appliance Technology Innovation Center Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangdong sits between Guandong Ocean University (40 patents, rank #8,036) and Holland Electronics , Llc (40 patents, rank #8,044) - the closest US assignees by grant volume. The composite Innovation Score of 63.4/100 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. Historical data spans 2022 through 2025, with 40 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. Guangdong Midea White Home Appliance Technology Innovation Center Co., Ltd.'s 14.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 39 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio
Guangdong's 40 grants land it in the top 2% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
