Time to first citation differentiated according to origin of the first citation. The empirically obtained distributions of the time lag Δt₁ until first citation are shown for the three different categories of first citations considered in this work: self-citations, in-community citations, and out-of-community citations. Results shown here for the latter two types of citation have been obtained based on the community structure identified by the Infomap algorithm on the largest connected component of the co-inventor network. The bin width is 2 months
