The UKIPO has adopted a number of procedures to provide applicants with a good idea of the chance of successful grant within the first few months from filing. This early certainty is helpful when utilising PPH and managing a global family of patents. The EPO is also well-known for its rigorous approach to the examination of patent applications, and as such a granted European patent is considered to be a valuable and high-quality asset. However, in the past this detailed level of search and examination has sometimes led to delays in the prosecution process, which have been frustrating for both applicants and third parties, and have resulted in a lack of legal certainty. Such delays can be particularly problematic in view of the trend for shortening product lifecycles.
