WUXI Esiontech Co., Ltd. has been granted 18 US utility patents between 2023 and 2025, placing WUXI Esiontech Co., Ltd. at #16,519 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, WUXI Esiontech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, WUXI sits between Whealthfields (hong Kong) Limited (18 patents, rank #16,505) and Wenzhou MTLC Electric Appliances Co., Ltd (18 patents, rank #16,513) - the closest US assignees by grant volume. The composite Innovation Score of 48.4/100 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 2023 through 2025, with 18 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. WUXI Esiontech Co., Ltd.'s 11.7 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 10 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
