Portfolio overview
HOYA Glass DISK (thailand) Ltd. has been granted 5 US utility patents between 2015 and 2017, placing HOYA Glass DISK (thailand) Ltd. at rank #47,400 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in G11B (INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER). As a Foreign Corporation, HOYA Glass DISK (thailand) Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, HOYA sits between Horsepower Technologies, Inc. (5 patents, rank #47,396) and HT Materials Corporation (5 patents, rank #47,404) - the closest US assignees by grant volume. The composite Innovation Score of 15.3/100 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 0 grants, compared with 5 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. HOYA Glass DISK (thailand) Ltd.'s 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HOYA Glass DISK (thailand) Ltd. against peers pursuing similar technology classes.
