Portfolio overview

Alabama Metal Industries Corporation has been granted 43 US utility patents between 2019 and 2025, placing Alabama Metal Industries Corporation at #7,516 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in E04F (FINISHING WORK ON BUILDINGS, e.g. STAIRS, FLOORS). As a US Corporation, Alabama Metal Industries Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Alabama sits between Array Technologies, Inc. (43 patents, rank #7,516) and BAE Systems Bofors AB (43 patents, rank #7,524) - the closest US assignees by grant volume. The composite Innovation Score of 33.9/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 38 grants, compared with 1 in the 2015–2019 window, a +3700% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Alabama Metal Industries Corporation's 8.5 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 8 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
