Intellectual Property Lawyers & Patent Attorneys

At Birkett Long, our intellectual property lawyers – an experienced team combining Chartered Patent Attorneys, European Patent Attorneys, and Chartered Trade Mark Attorneys, as well as UK and European-qualified solicitors - understand the importance of the identification and exploitation of your IP assets, keeping ahead of your competitors and developing your market offering.

We are the only law firm in the Eastern region which combines the deep technical knowledge of Patent and Trade Mark Attorneys with the broad experience of a 200 year old firm. We are able to help you not only with the filing and registration of patents, trade mark and design applications but also with the exploitation of the Intellectual Property they contain. If that is via manufacturing, then we have commercial property lawyers who can help you buy the land or the factory, employment lawyers to help you with staffing and corporate lawyers to advise on the structure of the company. If it is via licensing or franchising, our commercial lawyers can help with that.

We call this IP in context.

Our IP team has breadth and depth of experience in:

  • Filing UK patent applications
  • Filing European patent applications
  • Filing Unitary patent applications
  • PCT applications
  • The validation of European Patents in the UK
  • Patent applications worldwide 
  • UK trade marks
  • European trade marks
  • International trade marks
  • Worldwide trade marks
  • Design registrations
  • UK design registrations
  • European design registrations
  • International design registrations
  • Worldwide design registrations
  • Unregistered IP rights such as copyright and passing off
  • Intellectual Property dispute litigation and dispute resolution
  • Domain name disputes and seizures
  • Customs work and Seizures of counterfeit goods

As your business grows we can ensure that you have protection in place both in the UK and internationally. When the time comes, we can assist you in the enforcement of those rights.

Principally, the creation of IP assets is the creation of value. Birkett Long has experts on hand to help with the creation, realisation, maintenance and disposal of those assets, in order to help you maximise the value you can obtain from your ideas.

An idea can beget a patent application, which might be filed in the UK first, then subsequently elsewhere, either via the International Patent Application, which is formally known as the Patent Cooperation Treaty or “PCT”, or directly, in countries such the USA, China, Japan, India, or in regions such as Europe.

Likewise, a UK trade mark application can be used as a springboard for filing an international application (known as a “Madrid” or “Madrid Protocol” application) which can be used to cover up to 130 different countries, as an alternative to making individual filings in the USA, Europe or elsewhere.

Similarly, an international application (known as a “Hague” application) may be filed to cover a design registration, as well, as or instead of international filings in individual countries.

Birkett Long has a strong track record in getting patents, trade marks and design registrations granted all over the world and has applications pending and granted in well over a hundred different countries. We work for and have worked for some of the largest companies in the world, as well as numerous governmental departments.

Our IP lawyers, who have a wide range of qualifications, including attorney and solicitor qualifications, will guide you through the processes involved. Here are some of the issues we can assist you with:
