Latest PubChem News: Reaxys Integration, RESTful Interface, and Improved BioAssay Summaries

Last time we looked at the free chemical search platform PubChem, structures from the Therapeutic Target Database (TTD) and structures from IBM BAO (Business Analytics and Optimization) strategic IP insight platform (SIIP) became accessible through the portal.  Further updates related to system access and information display have taken place since March 2012, including an integration of PubChem onto the Reaxys platform,  a beta release of a RESTful web interface to PubChem data and services, and new information and display features on the PubChem BioAssay summary pages.  PubChem is a useful free resource for patent searchers conducting chemical prior art searches, both as a source of reference information and as a search resource (since the IBM structures on the platform are linked to patents and scientific literature).  Professional patent searchers will use a combination of subscription search systems, such as STN, and free resources like PubChem to conduct a comprehensive chemical prior art search.  It therefore helps to stay up-to-date on the latest news about central free resources like PubChem.

More Free Chemical Search Tools: Materials Project and ChemExper

Here at the Intellogist blog, we’ve discussed free online tools for chemical searches ranging from government resources, like the ever-trusty PubChem and the Chemical Data Access Tool from the EPA, to international tools like the Chinese chemical search tool ChemYQ. Here are two more free chemical search tools to add to the list:

  • Materials Project – A collaboration between Massachusetts Institute of Technology (MIT) and Lawrence Berkeley National Laboratory (LBNL) that provides users with access to a number of tools for searching and analyzing materials based on their various properties.
  • ChemExper (which I originally heard about through the CHMINF listserv) – A free chemical directory created by ChemExper Inc. that allows users to locate chemical products and suppliers.

The Materials Project site provides a number of research support tools that will be useful for patent searchers conducting chemical prior art searches who need to quickly locate detailed information on a particular material. ChemExper will help prior art searchers and chemists quickly locate suppliers for a particular material, and ChemExper also provides a chemical structure drawing tool that greatly enhances the search capabilities of the site.  After the jump, learn about the chemical search tools available on Materials Project and ChemExper!

The Evolution of Free Chemical Patent Searching: The New SureChemOpen

Since SureChem was purchased by Macmillan Publishers Ltd. in 2009, it has undergone a variety of changes that are chronicled in the Major Recent Updates section of the SureChem System Report on Intellogist. In April 2012, the SureChem website announced SureChemOpen, a free chemistry search product that was being launched prior to the release of two subscription search products (SureChemPro and SureChemDirect).  The SureChem website offers a comparison of all three products, and these features are listed for SureChemOpen:

  • $0 per month
  • Free patent chemistry search
  • Search and view patent chemistry and full text
  • Search SureChem patents alongside Royal Society of Chemistry journals and ChemSpider
  • No data export

Read on to learn more about the new SureChemOpen product, including the coverage, chemical patent search and viewing options, and how you can register to use the portal for free!

The Newest Chemical Patent Search Features on SciFinder

The STN Intellogist Report was recently updated, and we listed some of the major improvements to the product: new full-text patent databases, improvements to current full-text patent databases, improved bio-sequence and chemical structure search options, and new Assistants and Wizards on STN Express and STN on the Web. STN is a fantastic platform for expert searchers who’ve mastered the syntax of the command line interface, but novice searchers may prefer the simpler interface of the SciFinder platform, another search system produced by the Chemical Abstracting Service.  SciFinder offers access to many of the same CAS databases offered on STN, but through a much more user-friendly interface.  For a detailed comparison of STN and SciFinder, check out this blog post.

Like STN, SciFinder has seen a variety of updates to both content and search features in the last few months.  After the jump, we’ll look at the newest coverage and interface updates on SciFinder!

The Latest Data Updates on PubChem

The National Institute of Health first released PubChem in 2004, and today PubChem is an important free chemical search platform for patent searchers and other chemical researchers.  According to the “About” section, PubChem allows users to search for “information on the biological activities of small molecules,” and the chemical structures link to other Entrez resources, like PubMed scientific literature. This winter, two new data sources were added to PubChem, and patent searchers looking for prior art in the pharmaceutical and biotechnology fields may find useful data from both resources.

Free Chemical and Sequence Searching in Chinese Patent documents: ChemYQ and NASDAP

If Chinese non-patent literature searches are difficult for English-language prior art searchers, you can imagine how challenging chemical and genetic sequence searching within Chinese patent documents can be.  Many tools for chemical and genetic sequence searches in patent documents are available, both for free and by subscription, and many tools also exist for searching within Chinese-language patent documents.  Few tools, however, combine the Chinese patent coverage and chemical/genetic sequence search options; we’ve looked at only one subscription-based genetic sequence search tool, GenomeQuest, which recently added Chinese patent sequence data to their collection.  Today we’ll look at two free tools that can be used by English-language searchers to locate chemical names and genetic sequences within Chinese patent documents: ChemYQ and NASDAP.

After the jump, learn more about the Chinese chemical search engine ChemYQ and the Chinese genetic sequence search site NASDAP!
