Portfolio overview

Bitzer Kühlmaschinenbau Gmbh has been granted 109 US utility patents between 2015 and 2025, placing Bitzer Kühlmaschinenbau Gmbh at rank #3,390 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.0 claims per patent with primary concentration in F04C (ROTARY-PISTON, OR OSCILLATING-PISTON, POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS ; ROTARY-PISTON, OR OSCILLATING-PISTON, POSITIVE-DISPLACEMENT PUMPS). As a Foreign Corporation, Bitzer Kühlmaschinenbau Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Bitzer sits between West Pharmaceutical Services, Inc. (110 patents, rank #3,386) and Decathlon (109 patents, rank #3,394) - the closest US assignees by grant volume. The composite Innovation Score of 52.8/100 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 68 grants, compared with 41 in the 2015–2019 window, a +66% 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. Bitzer Kühlmaschinenbau Gmbh's 18.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bitzer Kühlmaschinenbau Gmbh against peers pursuing similar technology classes.
