Anti-tampering devices – fading boundaries of parallel trade?
Belgium | 06 February 2019

A legislative package aimed at fighting falsified medicines will enter into force in the European Union in early 2019. This EU legal framework was transposed into Belgian law through the Medicines Act and the Royal Decree concerning Medicines for Human and Veterinary Use. As a result, pharmaceutical companies will be required to affix a so-called 'anti-tampering device' on all prescription medicinal products to allow verification of whether the packaging has been tampered with.

GMO trial gets green light despite formal invalidity
Belgium | 08 May 2013

The government has implemented a strict regulatory framework for genetically modified organism field trials. But what happens when one of the players fails to respect the rules? Does it affect the valid work that has already been done by others? These questions recently arose before the Ghent Court of First Instance in the context of expedited civil proceedings initiated by Greenpeace against the Belgian state.

Desperate times call for ex parte interim measures in patent disputes
Belgium | 18 March 2019

Preliminary injunctions are rarely granted on an ex parte basis in Belgium and adversarial debates are considered a cornerstone of legal proceedings which can be deviated from only in cases of absolute necessity. However, ex parte interim measures have been granted in at least four patent disputes in Belgium in recent years, which helps to shed light on the circumstances under which patentees can consider them to be a measure of last resort to stop a threat of infringement.

Enantiomers and racemates: the same product?
Belgium | 05 December 2011

A Belgian court has invalidated Lundbeck's supplementary protection certificate (SPC) for escitalopram, the 'S' enantiomer of its racemate citalopram. The court held that escalitopram is the same product as citalopram, and that the former's SPC did not comply with Articles 3(c) and (d) of EU Regulation 469/2009. The court held that it was in the interests of patients to declare the decision provisionally enforceable.
