Complete Global Patent Landscape Dataset: Hydrothermal Synthesis of Nanodiamonds (1999–2024)

This dataset presents a comprehensive 25-year global patent landscape (1999–2024) detailing the technological evolution of the hydrothermal synthesis of nanodiamonds. The compilation systematically categorizes innovations in carbon-based nanostructure production from organic precursors, specifically tracking formulation parameters related to malic acid and citric acid ratios. Furthermore, the dataset maps critical processing milestones, including acid-boiling purification variables, yield scale-up strategies, and advanced material characterization benchmarks required for structural validation (HRTEM, Raman spectroscopy, XPS, Photoluminescence, and SAED). The indexing supports the ongoing development of biocompatible nanomaterials and clinical applications, such as hydrophobic, non-stick wound dressings and shellac-based materials. To optimize data filtration and meta-analysis for researchers, engineers, and legal experts, the repository is organized into three distinct, functional Microsoft Word matrices: Complete_Patent_Landscape.docx: The master structural registry documenting comprehensive patent publication numbers, international assignees, and core technological claims across the 25-year timeline. Sorted_Patent_Landscape.docx: A chronological index tracking the developmental timeline of processing milestones and synthesis evolution. Thematic_Patent_Landscape.docx: A categorized matrix grouping patents by specific chemical criteria, precursor utilization, and processing mechanics.
