Company patents
Allegro MicroSystems, LLC
Allegro MicroSystems, LLC's patent strategy reveals a surprising and significant emerging focus on "Magnets & Inductors," which saw an astonishing 1200.0% year-over-year growth in 2024 and another 92.3% in 2025, despite representing only 8.4% of its total portfolio. While "Electrical Measurement" remains its dominant category at 51.7% of the portfolio, its fluctuating yearly counts (e.g., -21.6% in 2024, +69.0% in 2025, and -59.2% so far in 2026) suggest a less stable, perhaps reactive, investment in its core area, contrasting with the consistent rapid growth in "Magnets & Inductors" and "Semiconductor Packaging & Encapsulation" (100.0% YoY growth in both 2024 and 2025).
