#11,612
of 50,000 tracked assignees
USPTO PatentsView assignee record - 26 granted patents across 31 technology areas, recorded in grant years 2015–2025. 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: C07C (ACYCLIC OR CARBOCYCLIC COMPOUNDS).
The verdict
According to USPTO PatentsView, CPC ranks #11,612 of 50,000 tracked US assignees by granted-patent volume, with 26 patents across 31 technology areas.
CPC Corporation, Taiwan has been granted 26 US utility patents between 2015 and 2025, placing CPC Corporation, Taiwan at #11,612 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in C07C (ACYCLIC OR CARBOCYCLIC COMPOUNDS). As a Foreign Corporation, CPC Corporation, Taiwan is one of the more focused assignees in the PatentsView dataset. By volume, CPC sits between Catarc Automotive TEST Center (tianjin) Co., Ltd (26 patents, rank #11,589) and Caterpillar Underground Mining Pty Ltd. (26 patents, rank #11,597) - the closest US assignees by grant volume. The composite Innovation Score of 46.3/100 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 12 grants, compared with 11 in the 2015–2019 window, a +9% 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. CPC Corporation, Taiwan's 14.3 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 31 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
CPC's 26 grants land it in the top 21% 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.
