USPTO PatentsView assignee record - 43 granted patents across 14 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C03B (MANUFACTURE, SHAPING, OR SUPPLEMENTARY PROCESSES).
The verdict
Glasstech holds 43 US patents across 14 technology areas, rank #7,560 of 50,000 tracked assignees.
Glasstech, Inc. has been granted 43 US utility patents between 2015 and 2025, placing Glasstech, Inc. at rank #7,560 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in C03B (MANUFACTURE, SHAPING, OR SUPPLEMENTARY PROCESSES). As a US Corporation, Glasstech, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Glasstech sits between Getrag Getriebe- Und Zahnradfabrik Hermann Hagen (43 patents, rank #7,556) and Hitachi Power Semiconductor Device, Ltd. (43 patents, rank #7,564) - the closest US assignees by grant volume. The composite Innovation Score of 41.6/100 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 16 grants, compared with 27 in the 2015–2019 window, a -41% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Glasstech, Inc.'s 18.1 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 Glasstech, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Glasstech's 43 grants land it in the top 33% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
