Portfolio overview
SHOWA DENKO MATERIALS CO., LTD. has been granted 144 US utility patents between 2020 and 2024, placing SHOWA DENKO MATERIALS CO., LTD. at rank #2,699 across all assignees tracked by PlainPatent. This portfolio spans 74 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a Foreign Corporation, SHOWA DENKO MATERIALS CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 59.4/100 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 2024, with 144 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. SHOWA DENKO MATERIALS CO., LTD.'s 13.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 74 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SHOWA DENKO MATERIALS CO., LTD. against peers pursuing similar technology classes.
