About Dror Shiftan, Ph.D.

Dror is a Patent Attorney in the Patents and Life Sciences Groups of PCZL’s Herzliya office. Dror’s experience as a scientific advisor and as an Israeli patent attorney encompasses the areas of pharmaceuticals, chemistry, and biology. Dror has also handled intellectual property matters ranging from patent prosecution to non-infringement and invalidity opinions involving pharmaceutical formulations, active compounds, and processes for preparing active compounds.

Dror is highly experienced in solving the three-dimensional structure of molecules, liquid and solid-state NMR, computer modeling and X-ray analysis, medicinal chemistry and rational drug design, polymer chemistry, and polymers as excipient for drug delivery.
