Company patents
6K Inc.
6K Inc. appears to be significantly shifting its patent strategy, as evidenced by a consistent decline across nearly all its major categories since 2023. For instance, its largest category, Powder Metallurgy (43.1% of portfolio), has seen a sharp decline of -53.8% in 2024, -66.7% in 2025, and -50.0% so far in 2026, while Electron / Ion Tubes & Discharge, representing 25.5% of its portfolio, has seen a -100.0% decline in 2026 after a -20.0% drop in 2024, indicating a broad de-prioritization of previously core areas.
