#25,994
Across all tracked assignees
USPTO PatentsView assignee record — 10 granted patents across 13 technology areas, active 2021–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B65H (HANDLING THIN OR FILAMENTARY MATERIAL, e.g. SHEETS, WEBS, CABLES).
CORELEX SHIN-EI CO., LTD. has been granted 10 US utility patents between 2021 and 2025, placing CORELEX SHIN-EI CO., LTD. at rank #25,994 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.9 claims per patent with primary concentration in B65H (HANDLING THIN OR FILAMENTARY MATERIAL, e.g. SHEETS, WEBS, CABLES). As a Foreign Corporation, CORELEX SHIN-EI CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.6/100 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 2021 through 2025, with 10 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. CORELEX SHIN-EI CO., LTD.'s 5.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CORELEX SHIN-EI CO., LTD. against peers pursuing similar technology classes.
