CIRD220300 - Patent Box: relevant IP profits: relevant IP income: medical use claims

It is not generally possible to patent a method of treatment of the human or animal body. Where, however, a new medical use is discovered for an existing compound or substance, this new medical use may be protected by a patent so long as the use is novel and inventive.

Before the update to the European Patent Convention (鈥楨PC鈥) in 2007, methods of treatment were considered not patentable as they did not have industrial applicability. However, a 鈥楽wiss Type鈥 claim along the lines of, 鈥渦se of a substance or composition X for the manufacture of a medicament for use in treatment of disease Y鈥 used to be an acceptable format for covering the new use.

The updated EPC specifically spells out that methods of treatment are not patentable but it does allow patenting of a substance for a specific medical use - in effect protecting use of the product for a specific treatment. So claims along the lines of, 鈥淪ubstance or composition X for the use in the treatment of disease Y鈥 may be considered novel so long as the use in the treatment of disease Y is novel. These are the new form of second medical use claims (鈥2MU鈥).

HMRC鈥檚 understanding is that both the old 鈥楽wiss Type鈥 claims and new 2MU claims are meant to be equivalent and can protect the same 鈥榯hing鈥, which can be taken to be a pharmaceutical product packaged/ labelled for an approved medical use.

For Patent Box purposes, where there is a patent protecting a pharmaceutical product packaged/ labelled for an approved medical use, that will be an item falling under Head 1 relevant IP income (S357BH(2)) regardless of whether it is a 鈥楽wiss Type鈥 claim or a new 2MU claim.
