Portfolio overview
LARGAN PRECISION CO., LTD. has been granted 1,046 US utility patents between 2015 and 2025, placing LARGAN PRECISION CO., LTD. at rank #433 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.6 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, LARGAN PRECISION CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 64.1/100 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 647 grants, compared with 399 in the 2015–2019 window — a +62% 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. LARGAN PRECISION CO., LTD.'s 23.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LARGAN PRECISION CO., LTD. against peers pursuing similar technology classes.
