Databases for Conducting Search for Chemical and Biotechnology Based Inventions

Chemical and biotechnology based inventions prior art search related tools can be categorized into based on their particular aspects and functions, such as follows:

  • Structures: For searching an exact structure, substructures within an exact structure and by generic Marpat formula, some of the handy databases are:
  • REGISTRY: Exact structures in the technical and patent literature which have been indexed by Chemical Abstract Service. Coverage started in 1957 and goes back to the early 1900s.
  • MARPAT: Generic Markush structures in patent publications since 1988 with additions before that date from the database of the French national institute of industrial property (INPI).
  • Beilstein: Incorporates the Beilstein Handbooks (original series to supplement IV; covers 1779-1959) and technical literature from 1960 to today.
  • Beilstein Crossfire database: Includes patent documents since 1976.
  • DWPI: Fragmentation codes for patent documents since 1963.
    • Derwent Chemistry Resource: Specific compounds in patent publications since 1999 as indexed by DWPI.
  • Polymers: Some of the specific polymer databases are:
    • REGISTRY: Monomer and SRU-based indexing; POLYLINK command for condensation polymers
    • DWPI: Polymer indexing since 1966
  • Pharmaceuticals: Some of the specific information resources for pharmaceuticals are.
    • REGISTRY: Compounds from technical and patent literature and catalogues which have been indexed by the Chemical Abstract Service
    • Chemical Abstracts Service (CAS): Patent publications and scientific articles since 1907
    • Derwent Chemistry Resource: Specific compounds from patent publications since 1999 as indexed by DWPI.
    • Marketing Databases and Press Releases: Adisinsight, Phar, Pharmaml, Toxcenter, Imspatents, Phin, Cbnb, Cin, etc.

Biosequences: For sequence searching, the searcher could look for nucleotide and amino acid sequences in patent publications or technical literature. Some specific resources include:

  • GQ-Pat: Sequences from the patent publications of all major patent offices including BRIC country patent publications.
  • REGISTRY: Sequences from technical and patent literature which have been indexed by the Chemical Abstract Service.
  • DGENE: Sequences from the patent literature which have been indexed by the World Patent Index.
  • PCTGEN: Sequences from digitally submitted PCT patent applications.
  • USGENE: Sequences from US patent and patent applications. Database description.

In addition, the following resources can be used generally for finding relevant art in the field of biotechnology and chemical sciences:

  • BIOSIS: BIOSIS covers original research reports, reviews, and selected U.S. patents in biological and biomedical areas, with subject coverage ranging from aerospace biology to zoology. Sources for BIOSIS include periodicals, journals, conference proceedings, reviews, reports, patents, and short communications. Bibliographic information, supplementary terms, abstracts, and CAS registry numbers are all searchable.

CHEMICAL ABSTRACTS: The Chemical Abstracts (CA) database is a widely used database which covers biochemistry and chemical engineering domains. CA contains records for documents from over 9,000 journals, patents from 26 countries and two international patent organizations. Moreover, most of the record including, bibliographic terms, indexing terms, and CAS registry numbers are searchable.
