Company patents
Monolithic 3D Inc.
Monolithic 3D Inc. has demonstrated a highly dynamic patent strategy, with a surprising surge in "Memory Devices (Structural)" patents in 2024, growing by +121.1% to 84 patents, indicating a strong, albeit short-lived, focus. However, the company appears to be rapidly shifting priorities across nearly all categories, with significant declines in patenting activity in 2025 and so far in 2026, including a complete cessation of new patents in "Integrated Circuit Layout & Arrangement" and "Transistor & Device Structure" in 2026.
