High Court of Delhi holds that writ petitions challenging pre-abolition orders of the Intellectual Property Appellate Board (IPAB) on trademark matters are to be heard by a Single Judge of the Intellectual Property Division (IPD), as per IPD Rules, 2021, unless falling under specific Division Bench exceptions in Delhi High Court Rules; rejects mandatory Division Bench listing, treating such petitions as original IPD proceedings for efficient adjudication post-IPAB dissolution.
