Patents provide inventors with a legally protectable monopoly over their inventions and protect new and innovative technical features of products and processes. They normally last for a limited period of 20 years depending on the country.
To qualify for patent protection, an invention must be:
To obtain a patent, an application for a patent needs to be filed; this will normally be with the patent office of the country where the inventor works.
Patents can provide a high level of protection and are highly important in some industries; this is clearly seen in the case of pharmaceutical companies, who spend millions of pounds and extensive time on research and development.
The process for registering a patent is not easy and can be expensive. It also exposes a product to competitors through public disclosure of the technology behind it without the competitor breaching the patent.
There are two types of patent infringement:
In regards to direct infringement, this covers activities relating to patented products, use of patented processes, offering patented processes for use and products obtained directly through patented processes.
Where the patented invention is a product, direct patent infringement occurs when the defendant:
Where the patented invention is a process, direct patent infringement occurs when the defendant:
A defendant may be guilty of indirect patent infringement where all of the following apply:
Claims relating to patents can be extremely technical and complex meaning they are often dealt with by specialist courts in both England and Wales. For this reason, we always recommend that claimants in patent infringement proceedings instruct specialist intellectual property solicitors. It is also quite common for a specialist intellectual property barrister to be instructed as well in order to advise claimants in patent infringement proceedings, assist with the drafting of necessary court documents and to represent claimants in court.
To make a claim, the claimant must be the proprietor of the patent or a co-owner of the patent or an exclusive licensee.
If infringement proceedings are contemplated, a claimant should first write a letter of claim to the potential defendant(s). This letter of claim should put the defendant(s) on notice of a claim and give the defendant(s) a reasonable amount of time (normally between 7 and 21 days) to respond to the claims made against them. The letter of claim must sufficiently identify the relevant patent(s) to enable the defendant(s) to evaluate them and formulate a view on infringement. The best way to do this is to provide copies of the relevant patent(s). All parties involved in patent infringement claims are expected to act reasonably in exchanging information and evidence prior to court proceedings being issued.
If the claim cannot be resolved then it is likely court proceedings will need to be issued. Claims for patent infringement are brought in the High Court, specifically in the Intellectual Property List of the Business and Property Courts. Lower value claims are brought in the specialist Intellectual Property Enterprise Court (IPEC) where capped costs operate. IPEC also has its own small claims track which deals with patent infringement cases which are worth less than £10,000.
To issue court proceedings, specific court documents will need to be drafted. These are normally a claim form and particulars of claim. There will also be a court fee payable to issue court proceedings which depends on the value of the claim and the relief sought. We always recommend that these documents are drafted by a barrister with assistance from a solicitor in order to ensure they comply with the court rules. These documents will identify the parties, state the cause(s) of action and the remedies sought.
The defendant(s) will then be given an opportunity to file and serve a defence to the claim (normally within 28 days of the court proceedings being issued but extensions of time can be agreed).
After that, the court is likely to order the parties to take the following steps to prepare the case for trial: disclosure of documents, witness statements and experts reports. It is our experience however that most patent infringement cases settle without the need for there to be a trial.
There are several remedies available for claimants when a claim for patent infringement is successful. These are as follows:
