Portfolio overview
HERAEUS QUARZGLAS GMBH & CO. KG has been granted 125 US utility patents between 2015 and 2025, placing HERAEUS QUARZGLAS GMBH & CO. KG at rank #3,037 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in C03B (MANUFACTURE, SHAPING, OR SUPPLEMENTARY PROCESSES). As a Foreign Corporation, HERAEUS QUARZGLAS GMBH & CO. KG is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 55.7/100 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 56 grants, compared with 69 in the 2015–2019 window — a -19% 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. HERAEUS QUARZGLAS GMBH & CO. KG's 13.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HERAEUS QUARZGLAS GMBH & CO. KG against peers pursuing similar technology classes.
