What this shows Changzhou Tronly Advanced Electronic Materials Co., Ltd. stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #19,591 of 50,000; Innovation Score 32.1/100 sits in the top 60% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Cavnue Technology, Llc (±0 grants).
Changzhou Tronly Advanced Electronic Materials Co., Ltd. has been granted 14 US utility patents between 2016 and 2023, placing Changzhou Tronly Advanced Electronic Materials Co., Ltd. at #19,591 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in C07D (HETEROCYCLIC COMPOUNDS). As a Foreign Corporation, Changzhou Tronly Advanced Electronic Materials Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Changzhou sits between Cavnue Technology, Llc (14 patents, rank #19,612) and Chicago Tag & Label, Inc. (14 patents, rank #19,620) - the closest US assignees by grant volume. The composite Innovation Score of 32.1/100 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 9 grants, compared with 5 in the 2015–2019 window, a +80% 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. Changzhou Tronly Advanced Electronic Materials Co., Ltd.'s 12.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 12 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
