Senior Stibbe telecoms specialist Egbert Dommering has become the latest partner to leave the firm to join a newly formed IP boutique, Brinkhof Advocaaten, which is made up of more than 15 lawyers from the Dutch leader and rival NautaDutilh.

The loss of Dommering, regarded as one of the Netherlands’ top telecoms and media lawyers, will be viewed as a blow to the Herbert Smith-allied firm, coming after the bulk of its IP group quit last month.
