Portfolio overview

ALFA Laval Corporate AB has been granted 306 US utility patents between 2015 and 2025, placing ALFA Laval Corporate AB at rank #1,367 across all assignees tracked by PlainPatent. This portfolio spans 85 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in F28F (DETAILS OF HEAT-EXCHANGE AND HEAT-TRANSFER APPARATUS, OF GENERAL APPLICATION). As a Foreign Corporation, ALFA Laval Corporate AB is one of the broader-portfolio assignees in the PatentsView dataset. By volume, ALFA sits between Naver Corporation (307 patents, rank #1,363) and Drägerwerk Ag & Co. KGAA (306 patents, rank #1,371) - the closest US assignees by grant volume. The composite Innovation Score of 59.1/100 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 151 grants, compared with 155 in the 2015–2019 window, a -3% 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. ALFA Laval Corporate AB's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 85 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ALFA Laval Corporate AB against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
