Mapping Matters: Why Patent Litigation Demands Technical Precision

Mold-Tek Packaging sued Neway Industries in Delhi High Court for infringing patents IN 401417 and IN 298724 covering container closure systems. Commercial Court initially granted injunction for both patents, later vacated it for IN 298724. High Court upheld injunction for IN 401417, finding Neway failed to prove invalidity through proper claim mapping. For IN 298724, court revived injunction and remanded invalidity question to Commercial Court, emphasizing distinction between infringement and invalidity defenses.
