Portfolio overview

Magna Closures Inc. has been granted 207 US utility patents between 2015 and 2025, placing Magna Closures Inc. at rank #1,940 across all assignees tracked by PlainPatent. This portfolio spans 66 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.9 claims per patent with primary concentration in E05B (LOCKS; ACCESSORIES THEREFOR; HANDCUFFS). As a Foreign Corporation, Magna Closures Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Magna sits between Fujitsu General Limited (207 patents, rank #1,936) and Swimc Llc (207 patents, rank #1,944) - the closest US assignees by grant volume. The composite Innovation Score of 60.7/100 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 135 grants, compared with 72 in the 2015–2019 window, a +88% 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. Magna Closures Inc.'s 17.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 66 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Magna Closures Inc. against peers pursuing similar technology classes.
