Company patents

Mueller International, LLC

Mueller International LLC's patent strategy reveals a significant shift away from its core Pipes & Tubing (41.3% of portfolio) and Valves (26.9% of portfolio) categories, which saw substantial declines of -59.4% and -50.0% respectively in 2025, suggesting a re-evaluation of traditional product lines. Surprisingly, despite a broad decline across many categories in 2024, the company showed an emerging focus on Machine Testing, with a 33.3% increase in patent filings so far in 2026, indicating a potential pivot towards quality assurance or diagnostic technologies within manufacturing.
