What Is a Patent Attorney
A patent attorney is a specialist legal professional who helps inventors and businesses protect technical inventions. Their work can include assessing patentability, preparing patent applications and responding to questions raised by patent offices during examination.
Combining scientific or engineering knowledge with legal training allows a patent attorney to understand how an invention works and identify the features that may be suitable for protection.

How Our Patent Attorneys Can Help
You may be considering your first patent application, developing an existing portfolio or dealing with a dispute. We can advise at different stages, taking account of the technology involved and what you want to achieve.
Assessing Your Invention
We can assess whether your invention may qualify for patent protection and advise on appropriate patent searches. Your attorney can explain what the results mean and how they may affect the scope of an application.
Preparing and Filing Applications
Your attorney prepares the description and claims that set out your invention and the protection being sought. We can also advise on overseas applications, helping you consider where protection is relevant to your business.
Managing Applications and Granted Patents
We handle patent office correspondence, explain examination objections and advise on responses and amendments. Once a patent is granted, we can continue to assist with renewals and portfolio management.
Licensing and Patent Disputes
We can advise on licensing your patent and on suspected infringement. If someone alleges that your business infringes their rights, our team can help assess the position and discuss your options.
