USPTO PatentsView assignee record - 20 granted patents across 21 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C08J (WORKING-UP; GENERAL PROCESSES OF COMPOUNDING; AFTER-TREATMENT NOT COVERED BY SUBCLASSES C08B, C08C, C08F, C08G or C08H).
The verdict
PI holds 20 US patents across 21 technology areas, rank #14,845 of 50,000 tracked assignees.
PI Advanced Materials Co., Ltd. has been granted 20 US utility patents between 2020 and 2025, placing PI Advanced Materials Co., Ltd. at rank #14,845 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. The composite Innovation Score of 53.4/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Historical data spans 2020 through 2025, with 20 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. PI Advanced Materials Co., Ltd.'s 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark PI Advanced Materials Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
PI's 20 grants land it in the top 9% 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.
