Avoid these mistakes

Common mistakes

  • Missing the two-month opposition window after acceptance
  • Filing a thin Statement of Grounds and Particulars that forfeits grounds
  • Relying on reputation without credible survey or sales evidence
  • Missing deadlines in the evidence stages (extensions are discretionary)
  • Pleading section 44 only and overlooking stronger section 60 / 62A grounds
