Official technical record

The patent lineage

Nine collected publications trace the documentary path from a 1982 distillation apparatus through later water-treatment applications.

What a patent can show

A patent documents disclosures and legal claims. Issuance does not prove commercial performance, medical benefit, safety, or independent replication.

International family

The archive preserves the WIPO pamphlet, priority document, International Preliminary Examination Report, and status report for WO2001068214, plus the manually retrieved CIPO document set for CA2403082. Australian and European family records were identified, but the 2026 automated capture did not obtain complete official national-office files.

What remains unresolved

  • How later application claims map precisely onto commercial machines.
  • Whether cited performance claims were independently replicated under controlled conditions.
  • The complete legal status and prosecution history of every international family member.
