Portfolio overview

PI Advanced Materials Co., Ltd. has been granted 20 US utility patents between 2020 and 2025, placing PI Advanced Materials Co., Ltd. at #14,862 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in C08J (WORKING-UP; GENERAL PROCESSES OF COMPOUNDING; AFTER-TREATMENT NOT COVERED BY SUBCLASSES C08B, C08C, C08F, C08G or C08H). As a Foreign Corporation, PI Advanced Materials Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, PI sits between Penthera Partners, Inc. (20 patents, rank #14,841) and Purpose Co., Ltd. (20 patents, rank #14,849) - the closest US assignees by grant volume. The composite Innovation Score of 53.4/100 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 2020 through 2025, with 20 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. PI Advanced Materials Co., Ltd.'s 11.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 21 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
