What happens next?

When we receive your form and fee, we will carry out a full and detailed examination of your patent application to find out whether:

• it claims an invention that we can grant a patent for
  
  
• it is new and not obvious
  
  
• the description is full and clear enough for the invention to be made or carried out by someone with a good knowledge of the technical area that the application is about, and
  
  
• the claims are clear and agree with the description of the application.

We will let you know if we find any problems with your application, and give you a chance to have your say about any problems raised.
