Portfolio overview

HERAEUS KULZER GMBH has been granted 17 US utility patents between 2015 and 2021, placing HERAEUS KULZER GMBH at rank #16,853 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in A61C (DENTISTRY; APPARATUS OR METHODS FOR ORAL OR DENTAL HYGIENE). As a Foreign Corporation, HERAEUS KULZER GMBH is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 31.0/100 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 2 grants, compared with 15 in the 2015–2019 window, a -87% 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 KULZER GMBH's 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HERAEUS KULZER GMBH against peers pursuing similar technology classes.
