“Virtual” molecular compounds, created in molecular modeling software, are increasingly useful in the process of rational drug design. When a physical compound is patented, however, virtual use of the compound allows researchers to circumvent the protection granted to the patentee. To acquire protection from unauthorized use of compounds in their virtual form, patentees must directly claim the virtual compound. But Supreme Court decisions such as Bilski v. Kappos and Mayo Collaborative Services v. Prometheus Laboratories, Inc. call into question whether virtual compound claims are patentable subject matter under § 101. Using the guidance offered by the Supreme Court and Federal Circuit, this Issue Brief argues that virtual compound claims are not abstract ideas and therefore, consistent with patent policy, qualify as patentable subject matter.
