Recognising where the value lies: the same legal tools are available to everyone but not everyone knows how to use them to maximum effect.

A lot of value can be tied up in IP so it is often very important for those with IP issues to get really good advice. A key challenge for many ley clients however is to find a good IP advisor. This is often however done in a somewhat ad hoc way: my cousin’s partner went to school with someone who does IP. If you are lucky this can work but it can also go spectacularly wrong. As a strategy it fails to factor in any consideration of the qualities that make a good IP advisor, such as:

  • A good listener

    Advice is only good advice if it assists the client achieve its commercial objectives. A good advisor will take the time to properly understand both what the client’s commercial objectives are and also the position the client finds itself in.

  • Deep experience of similar situations

    Given the importance of intellectual property to business, handling IP disputes and the commercialisation of IP rights, you don’t want someone running your case who is learning on the job. You want decades of experience.

  • Strategic thinking

    IP disputes can be very complex and it can be all too easy not to miss the points that are really going to matter. A good IP lawyer will work with you to devise a clear strategy based around a well-thought out theory of the case.

  • Smart

    A good IP lawyer will have the ability to get up to speed with the key aspects of a new complex technology quickly. They will also have a very good knowledge of the law and be excellent at expressing themselves both in writing and orally.

  • Attention to detail

    The details matter in IP cases and a good lawyer will have great attention to detail but will still be able to see the wood for the trees.

  • Integrity

    A good lawyer is not influenced by their own self-interest but will genuinely put the client’s interests and needs first. This is a very important factor as there will often be a huge disparity in understanding between the lawyer and the client such that the client is heavily reliant on the lawyer to recommend a strategy which is optimal for the client and not the lawyer.

  • Good in the trenches

    IP litigation can be a fast paced tough game. Some times the pressure is intense and the hours almost non-stop for days or weeks at a time. Does your lawyer have the resilience required.

  • Confident but not over-confident

    A good IP lawyer will not be pushed around and made to dance to the opponent’s tune but will also not be complacent about the merits of his own client’s case which he will continually question.

  • Organised

    Dealing with IP disputes that go to court is somehwhat like fighting a large scale military battle: often the outcome is determined well before the trial or battle begins. The team that has been better organised and kept track of all issues and documents has an enormous advantage over the team that less organised.
