Background to medical use claims

Second (and subsequent) medical use patent claims are specific to the pharmaceutical/biotechnology industry and are used to define the scope of an invention by way of a specified medical use. For an introduction to these and other types of patent claims, see Practice Note: Major types of patent claims.

There are two different types of second medical use claim which are described in more detail below. The inclusion of a medical use as a feature in a claim has implications for the claim’s patentability and its scope of protection.

To understand the background of second medical use claims it must be appreciated that they came about under the previous 1973 version of the European Patent Convention (EPC 1973) which has since been succeeded by the EPC 2000.
