A typical example from WO-2016199761-A1 represents a reaction shown in figure . The reaction product is a plant disease control agent of interest for the agrochemical community and described in PubChem as CID 140317046, provided by the WIPO to PubChem but without reference to the respective patent. It is also part of SciWalker's chemistry compound database with its identifier OCID 190138015958 but not found as a compound in WO-2016199761-A1. Similarly, it was not found in Google Patents. In another example from the United States Patent Office (USPTO), US-08680111-B2 is a patent of high interest for drug discovery -this Pfizer patent describes novel compounds that inhibit anaplastic lymphoma kinase (ALK) and was published in 2014. Its CWU files contain 1 sequence listing of a 13-mer peptide KKSRGDYNTMQIG in XML format, in total 238 TIF image files, as well as 234 Chemdraw CDX files and 234 MDL MOL files. In addition, 1 drawing with a crystal structure and 3 not interpretable image files are found. The chemical structure files were created by the USPTO from the images originally as Chemdraw files and then exported also as MDL MOL files.
