Portfolio overview

Powdertech Co., Ltd. has been granted 42 US utility patents between 2015 and 2025, placing Powdertech Co., Ltd. at rank #7,759 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.6 claims per patent with primary concentration in G03G (ELECTROGRAPHY; ELECTROPHOTOGRAPHY; MAGNETOGRAPHY). As a Foreign Corporation, Powdertech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Powdertech sits between Petroliam Nasional Berhad (petronas) (42 patents, rank #7,755) and S.a. Lhoist Recherche Et Développement (42 patents, rank #7,763) - the closest US assignees by grant volume. The composite Innovation Score of 37.8/100 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. Between 2020 and 2025 the company received 31 grants, compared with 11 in the 2015–2019 window, a +182% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Powdertech Co., Ltd.'s 9.6 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 Powdertech Co., Ltd. against peers pursuing similar technology classes.

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.
