MERGED MARKUSH SERVICE

Derwent and INPI (the French Patent Office) have collaborated to produce an exclusive searchable patent information resource for the pharmaceutical and chemical industry. The Merged Markush Service is the first product of this collaboration, providing a joint file which combines the existing MPHARM and World Patents Index Markush (WPIM) files on Markush DARC. This enables precise, comprehensive retrieval within the online text-based files — PHARMSEARCH and Derwent World Patents Index.

Features

  • A single database for incorporating the added-value chemical patent structure indexing produced by Derwent and INPI (originally separately available in WPIM and MPHARM)
  • Ongoing coverage to be supplemented by a substantially-enhanced backfile (20 years) within two years
  • Major country coverage
