Portfolio overview

HARBURG-FREUDENBERGER MASCHINENBAU GMBH has been granted 19 US utility patents between 2015 and 2023, placing HARBURG-FREUDENBERGER MASCHINENBAU GMBH at rank #15,328 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in B29D (PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE). As a Foreign Corporation, HARBURG-FREUDENBERGER MASCHINENBAU GMBH is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 29.2/100 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 12 grants, compared with 7 in the 2015–2019 window, a +71% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. HARBURG-FREUDENBERGER MASCHINENBAU GMBH's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HARBURG-FREUDENBERGER MASCHINENBAU GMBH against peers pursuing similar technology classes.
