Essilor International

Essilor International has been granted 606 US utility patents between 2015 and 2025, placing Essilor International at rank #755 across all assignees tracked by PlainPatent. This portfolio spans 94 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 claims per patent with primary concentration in G02C (SPECTACLES; SUNGLASSES OR GOGGLES INSOFAR AS THEY HAVE THE SAME FEATURES AS SPECTACLES; CONTACT LENSES). As a Foreign Corporation, Essilor International is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 62.6/100 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. Between 2020 and 2025 the company received 460 grants, compared with 146 in the 2015–2019 window — a +215% 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. Essilor International's 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 94 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Essilor International against peers pursuing similar technology classes.
