The European Patent Office's patent information system ESPACENET has been a great free resource for many years now. I regularly recommend it to clients, and when talking about IP for people looking for patent information to drive innovation. In many cases, you can quickly see if an idea is already known or not.
The EPO has just released a major update of the system and it's now even better and worth having a look at! Please take a look at:
EU trade mark registrations will still be possible for UK companies after BREXIT.
The UK rights in existing EU registrations will become separate UK national registrations after BREXIT under a new registration number, and will require separate renewal payments. I have been busy setting up cases for those new UK national registrations for current clients to compliment their EU registrations.
