Abstract From the Canadian patent

The invention contemplates a composition containing a multispecific ligand containing at least a first, ligand binding moiety and a second ligand binding moiety. The first ligand binding moiety, specifically binds with a pre-selected first affinity to at least a first ligand. The first ligand has a first, biodistribution. The second ligand binding moiety specifically binds with a pre-selected affinity to at, least a second ligand. The second ligand has a second biodistribution. The affinities of first and, second ligand binding moieties are selected to bias the biodistribution of the multispecific ligand in, favour of a selected location of one or both of the ligands.

Why it's free to use

  • Filed September 19, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 19, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 19, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
