The verdict
ALFA holds 6 US patents across 3 technology areas, rank #38,606 of 50,000 tracked assignees.
ALFA Laval Vicarb SAS has been granted 6 US utility patents between 2018 and 2025, placing ALFA Laval Vicarb SAS at rank #38,606 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.8 claims per patent with primary concentration in F28D (HEAT-EXCHANGE APPARATUS, NOT PROVIDED FOR IN ANOTHER SUBCLASS, IN WHICH THE HEAT-EXCHANGE MEDIA DO NOT COME INTO DIRECT CONTACT). As a Foreign Corporation, ALFA Laval Vicarb SAS is one of the more focused assignees in the PatentsView dataset. By volume, ALFA sits between Alesi Surgical Limited (6 patents, rank #38,602) and Allergan Holdings France S.a.s. (6 patents, rank #38,610) - the closest US assignees by grant volume. The composite Innovation Score of 30.8/100 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 3 grants, compared with 3 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Vicarb SAS's 18.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ALFA Laval Vicarb SAS against peers pursuing similar technology classes.

How to use this portfolio
ALFA's 6 grants land it in the top 64% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
