    WIPO PATENTSCOPE chemical search project RFP & RFI:

    [2]. PTD/14/076 - Addition of Chemical Search capabilities to the WIPO PATENTSCOPE search system,  Request for proposal. Published on 30-Jan-2015

    WIPO has issued this RFP (Request for Proposal) in order to obtain financial offers from the key Service providers in the Chemical Search consultancy field in response to the requirements outlined below. Different kinds of texts are indexed in PATENTSCOPE: patent titles, abstracts, description and claims. The goal of this project is to add to PATENTSCOPE “exact”  search capabilities for chemical compounds in these fields, in the sense that chemical fuzzy search, sub-compound search and Markush search are currently out of scope of this project.

    The main issue to solve is recognition of the numerous different ways to refer to a given chemical compound in a patent application: accepted name, commercial name, IUPAC name, CAS name, CAS registry number, InChI, SMILES, embedded drawing, MOL file, etc. The idea is to enrich the texts indexed in PATENTSCOPE by replacing the detected compounds by their corresponding IUPAC International Chemical identifier key (InChIKey).

    A first usage of these new indexation capabilities will be the implementation of a search capacity for International Nonproprietary Names (INNs) that can be represented by an InChIKey in PATENTSCOPE which may be used by the public at large (INNs are standard names of pharmaceutical drugs designated by the World Health Organization (WHO)).

    Processing pipelines should be developed, taking in parameter source text strings of patent applications in HTML, localizing the references to chemical compounds (from substrings of text and embedded images), determining the compounds chemical structures and outputting the enriched text, replacing each found source text/image with the corresponding computed InChI key.

    An intuitive chemical search graphical interface should be developed as an additional menu item “Chemical compounds” under PATENTSCOPE main search drop down menu item.

    …The last big enhancement of the [PATENTSCOPE] system was the addition of chemical search capabilities, accomplished using InfoChem’s automatic text- and image-mining technologies. An automatic workflow was developed and put into operation allowing real-time, multi-modal chemical text annotation and image recognition. Since the number of patent applications in some Asian countries increases rapidly, this process was enhanced to also handle Russian, Korean, Japanese and Chinese files in the most recent project phase. This talk will report the results and will address technical challenges encountered such as OCR quality, heterogeneity of sources, scalability, performance and parallelization.

    One of “driving forces” of the projects (cited in [7, p.11]), were needs of WHO procurement agencies in patent clearence using public databases:

    [10]. WIPO Secretariat, 2014. Feasibility Study on the Disclosure of International Nonproprietary Names (INN) in Patent Applications and/or Patents. Standing Committee on the Law of Patents. Twenty-First Session. Geneva, November 3 to 7, 2014 (No. SCP/21/9).

    23...[Medicines] procurement agencies have to consider the patent status of products early in the procurement process. Unlike IP professionals, they often do not have access to commercial patent databases specialized for chemistry and pharmaceuticals search, and thus conduct patent search on publicly available, free sources. As health specialists, they are familiar with INN, and some consider it problematic that a list of patents relating to a particular pharmaceutical product cannot be obtained by a patent search using the corresponding INN as a keyword without employing patent classifications or conducting chemical structure (or chemical name) search. (p.7)
    57. With the development of computing technology, it appears that automatic identification, extraction and indexing of chemical data from a source (such as patent documents) with complex software algorithmsis increasingly practical...A query with an INN could be automatically translated into other queries that correspond to its chemical name, structure etc., and software will carry out a set of comprehensive queries. (p.17)

    …We now report the additional ability to detect, normalize, and replace chemical names in documents with InChiKeys and then index the combined text and embedded InChi's using SOLR, a Lucene-based full text-indexing engine. The resulting index supports Boolean combinations of chemical compounds and regular text words and phrases. It also supports proximity searching. The net result is that we can now perform searches for exact chemical structures or even unspecified chemical structures within a specified context.
