Patent infringement

Patent infringement

Patent litigation is a complex area of law which requires specialist legal and technical expertise. If you have a patent infringement issue it is essential that you seek professional advice without delay. As a specialist intellectual property firm we are accustomed to acting for patent rights holders as well as alleged patent infringers.

What is a patent?

Patents are a powerful tool for businesses to protect an invention which is new, involves an inventive step and which is capable of industrial application.

Examples of the type of things which a patent may cover are: mechanical, medical or electronic devices, chemical compounds, or methods for doing certain things.

A patent must be registered with the European Patent Office (EPO) or the UK Intellectual Property Office (UKIPO) and usually lasts for 20 years.

Once a patent is registered, an owner can prevent a third party from using the invention described in the ‘claims’, even if that person develops the invention independently.

Patent infringement

A patent gives its owner a right to stop other people from reproducing or commercialising the invention without the inventor’s authorisation.

A patent is usually infringed if a product or method embodies or does each of the features or steps in the ‘claims’.

What remedies are available for patent infringement and passing off?

Compensation for patent infringement will vary from case to case, but usually includes:

  • an injunction preventing the infringement;
  • recovery of damages or an account of the infringer’s profits;
  • delivery-up or destruction of any infringing goods;
  • recovery of portion of the legal costs incurred enforcing the patent rights.

How we can help

We can help you with the following:

  • assess the prospects of success for any patent infringement;
  • prepare a cease and desist letter or, as appropriate, a response to any cease and desist letter, clearly setting out your position and complying with all requirements of the UK courts;
  • look into practical ways to resolve your dispute without court action;
  • if your dispute is not resolved and goes to court, robustly presenting your case.
