Portfolio overview

II-VI Delaware, Inc. has been granted 350 US utility patents between 2019 and 2025, placing II-VI Delaware, Inc. at rank #1,214 across all assignees tracked by PlainPatent. This portfolio spans 81 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.0 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a US Corporation, II-VI Delaware, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Ii-vi sits between Shenzhen Smoore Technology Limited (351 patents, rank #1,210) and Amdocs Development Limited (349 patents, rank #1,218) - the closest US assignees by grant volume. The composite Innovation Score of 68.6/100 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 341 grants, compared with 9 in the 2015–2019 window, a +3689% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. II-VI Delaware, Inc.'s 18.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 81 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark II-VI Delaware, Inc. against peers pursuing similar technology classes.
