Portfolio overview

Institut D'optique Graduate School has been granted 8 US utility patents between 2017 and 2024, placing Institut D'optique Graduate School at rank #32,031 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in G02F (OPTICAL DEVICES OR ARRANGEMENTS FOR THE CONTROL OF LIGHT BY MODIFICATION OF THE OPTICAL PROPERTIES OF THE MEDIA OF THE ELEMENTS INVOLVED THEREIN; NON-LINEAR OPTICS; FREQUENCY-CHANGING OF LIGHT; OPTICA). As a Foreign Corporation, Institut D'optique Graduate School is one of the more focused assignees in the PatentsView dataset. By volume, Institut sits between Inoac USA, Inc. (8 patents, rank #32,027) and Instituto DE Telecomunicaçöes (8 patents, rank #32,035) - the closest US assignees by grant volume. The composite Innovation Score of 35.1/100 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 4 grants, compared with 4 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Institut D'optique Graduate School's 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Institut D'optique Graduate School against peers pursuing similar technology classes.
