Hi Ben,
I've just recently joined this group.
IP lawyers are the people usually responsible for handling litigation
matters (however, they may also enrol the services of a barrister).
An IP lawyer is different to a Patent Attorney (I am a Patent
Attorney) who provides advice on how to protect your IP. The patent
law limits the acts that a Patent Attorney can perform in relation to
court proceedings, but we are able to act for a client in front of IP
Australia. There are however a handful of patent attorneys who are
also IP lawyers.
Many IP lawyers specialise in specific matters, such as contractual
breaches, trade mark infringement, patent infringement, copyright
infringement etc. Therefore, it is recommended that you find someone
suited to your specific requirements.
All the best
