USPTO PatentsView assignee record - 9 granted patents across 5 technology areas, active 2015–2022. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search.

The verdict
Albemarle holds 9 US patents across 5 technology areas, rank #28,006 of 50,000 tracked assignees.
Albemarle Europe SRL has been granted 9 US utility patents between 2015 and 2022, placing Albemarle Europe SRL at rank #28,006 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.2 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, Albemarle Europe SRL is one of the more focused assignees in the PatentsView dataset. By volume, Albemarle sits between Aisin Fukui Corporation (9 patents, rank #28,002) and Alfred E. Tiefenbacher (gmbh & Co. Kg) (9 patents, rank #28,010) - the closest US assignees by grant volume. The composite Innovation Score of 28.8/100 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 6 in the 2015–2019 window, a -50% 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. Albemarle Europe SRL's 14.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Albemarle Europe SRL against peers pursuing similar technology classes.

How to use this portfolio
Albemarle's 9 grants land it in the top 71% 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.
