Company patents

DelStar Technologies, Inc.

DelStar Technologies, Inc's patent strategy reveals a strong, albeit fluctuating, focus on core materials science, with "Separation Processes (Filtration, Distillation)" representing 43.4% of its portfolio and experiencing a significant 300.0% YoY growth in 2025 before a -16.7% decline so far in 2026. Surprisingly, despite a substantial investment in "Layered Products (Laminates, Films)" with a 300.0% YoY growth in 2024, this category has seen a sharp decline of -58.3% in 2025 and -40.0% so far in 2026, indicating a shifting priority away from this area, while emerging interests in "Implants & Prosthetics" and "Sterilization & Biocompatible Materials" saw 100.0% YoY growth in 2025 before a complete decline so far in 2026.
