Portfolio overview

Vitro Flat Glass Llc has been granted 79 US utility patents between 2019 and 2025, placing Vitro Flat Glass Llc at rank #4,498 across all assignees tracked by PlainPatent. This portfolio spans 37 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA). As a US Corporation, Vitro Flat Glass Llc is one of the more focused assignees in the PatentsView dataset. By volume, Vitro sits between Thorlabs, Inc. (79 patents, rank #4,494) and Aselsan Elektronik Sanayi VE Ticaret Anonim Sirketi (78 patents, rank #4,502) - the closest US assignees by grant volume. The composite Innovation Score of 56.5/100 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 75 grants, compared with 4 in the 2015–2019 window, a +1775% 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. Vitro Flat Glass Llc's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 37 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Vitro Flat Glass Llc against peers pursuing similar technology classes.
