% Pajek network converted to sparse adjacency matrix for inclusion in UF sparse 
% matrix collection, Tim Davis.  For Pajek datasets, See V. Batagelj & A. Mrvar,
% http://vlado.fmf.uni-lj.si/pub/networks/data/.

% Regarding conversion for UF sparse matrix collection: in the original data    
% there are 14,973,817 edges (unweighted).  Of this, 3050 are duplicates        
% This graph is binary; the duplicates have been removed.                       
% Also, the original data has auxiliary data for all 6,009,554 US Patents in the
% time period.  This patent network has only 3,774,768 patents, and the auxiliar
% data (appyear, class, etc.) is matched here to the nodes of the graph.
