LIDDS: Patent term extension until 2032 for NanoZolid® technology

An external analysis concludes that a five years patent extension is expected in Europe and predicts a similar extension procedure in the US provided that the pharmaceutical substances in NanoZolid based products are not on the market.

The patent term extension for the technology patent covering NanoZolid in combination with non-marketed active substances can include 2-hydroxyflutamide for treatment of localized prostate cancer (Liproca® Depot) or other products under development by LIDDS. The five year patent extension until 2032 can be expected in Europe and predicts a similar procedure in the US.  In Europe the extension is called Supplementary Patent Certificate (SPC) and the corresponding US procedure is labelled Patent Term Extension (PTE). For the PTE the exact extension term cannot be determined in advance, as it depends on the duration of the regulatory review in the US. Similar patent term extension procedures exist in key markets in Asia and South America.
