Company patents
Sakuu Corporation
Sakuu Corporation's patent strategy is heavily concentrated in manufacturing, with Plastics Shaping & Molding (83.1% of portfolio) and Additive Manufacturing (3D Printing) (78.5% of portfolio) being dominant areas, both showing significant year-over-year fluctuations, including a sharp decline so far in 2026. Despite this manufacturing focus, the consistent patenting in Batteries & Fuel Cells, maintaining a 0.0% YoY growth in 2024 and 2025 before a decline so far in 2026, suggests a steady, albeit not rapidly expanding, commitment to energy storage technologies.

Process and equipment for producing solid-state battery cells, including solid electrolyte synthesis (sulfide/oxide/polymer), thin-film deposition, lamination, sintering, dry-electrode fabrication, and stacking under controlled atmosphere.
Active anode materials and manufacturing techniques for rechargeable lithium-ion batteries, including silicon-carbon composites, graphite, lithium-metal anodes, and electrode coating processes that improve capacity, cycle life, and rate capability.
Integration of additive manufacturing with subtractive manufacturing (e.g., machining, cutting) or other traditional processes within a single system or workflow to create parts with improved features, surface finish, or material properties, or to enable new manufacturing paradigms.
Mechanisms and methods for preventing or removing clogs, ink residue, or contaminants from printhead nozzles and surfaces to ensure consistent print quality and extend printhead lifespan.
Systems and methods for real-time sensing, modeling, and closed-loop control of additive manufacturing parameters to ensure part quality, consistency, and process efficiency. This includes thermal management, atmospheric regulation, and precise material deposition.
Techniques for combining multiple materials or layers, often with specialized surface treatments, coatings, or assembly methods, to create functional or aesthetically enhanced plastic articles, including consumer goods and encapsulated electronics.
Slurry compositions and coating processes for battery electrodes, including binder/active-material slurries, surface coating layers, and electrode-to-foil adhesion for cathode and anode.
Specialized cleaning techniques and apparatus designed for removing microscopic contaminants, residues, or films from sensitive substrates, such as semiconductor wafers or flat panel displays, often involving chemical, mechanical, or plasma-based methods.
Innovations in the design and arrangement of piezoelectric or thermal actuators, drive electronics, and fluidic structures within the printhead to achieve precise and efficient liquid ejection.
Processes and apparatus for disassembling spent batteries and recovering valuable materials (e.g., metals, electrolytes, plastics) through mechanical, chemical, or electrochemical methods for reuse or sustainable disposal.
