Immune checkpoint inhibitors: a patent review (2010-2015)

Immune checkpoint inhibitors are now widely accepted as a key component of the therapeutic strategies in cancer. This fervent activity creates a maze of third-party patents that pose considerable risks for both newcomers and established companies. We can thus anticipate that the number of patent conflicts and disputes will increase in the near future. Treatments will involve combination therapy comprising at least one immune checkpoint inhibitor and companies will multiply patent filings in this field. Finally, we can expect that patents related to biomarkers that will render a patient eligible to a treatment with an immune checkpoint inhibitor will have tremendous commercial value.
