Priority: Pitfalls & Practical Points

Priority under the EPC is a complex topic. Although it is unusual for an EP Examiner to investigate whether a priority claim for a patent application is valid or not during substantive examination, the consequences of a decision that a priority claim is invalid can be huge: e.g. the loss of a patent. In this webinar, we will discuss briefly the legal framework under the EPC for assessing priority, identify possible pitfalls that can arise and also provide some practical points, including some things to think about when filing a PCT/EP application claiming priority to a first application (and particular issues when the first application is a US provisional application) and EPO/UKIPO requirements when filing requests to record assignments.
