-        PatCID is a collection of molecular structures to speed up discovery of new molecules, automatically and at scale with
-        Deep Search. This large-scale collection was created by processing molecular images in United States, European,
-        Japanese, Korean, and Chinese patents. We have applied a graph-based visual recognition model to obtain high-precision
-        conversion of these molecular images (MolGrapher, ICCV2023, accepted).
+        PatCID is a collection of chemical structures in patent documents to facilitate search of patent documents in the
+        organic-chemistry domain. Programmatic access to PatCID can facilitate discovery of molecules. This collection was
+        created by processing molecular-structure images in United States Patent and Trademark Office, Japan Patent Office,
+        European Patent Office, Korean Intellectual Property Office, and China National Intellectual Property Administration
+        patent documents. (PatCID: Chemical Structures in Patent Documents, Nature Communications 2024; MolGrapher: Graph-based
+        Visual Recognition of Chemical Structures, ICCV 2023).
