Patent layout note: The 19 granted patents above are on file as original certificates. In addition, 13 patent applications are currently under substantive examination; this page will be updated once they are granted. The total patent layout is 32 filings (19 granted + 13 under examination).

Why this matters: The dual-line patent layout covering pumps and filling equipment protects both core components (rotors, pump bodies, hopper pressing-down devices) and complete machines. It documents the company's independent R&D capability and continuous product iteration, which matters to buyers evaluating long-term technology partners.
