Finding patents

Specialist patent databases

Many specialist patent databases are freely available on the Internet. 

Most of these databases will allow you to see the full-text of the patent application.

Examples include:

  • Citing and cited patents are indexed
 
Espacenet
  • Visit Espacenet
  • Produced by the European Patent Office and INPADOC, Expacenet covers 80 countries and is one of the most popular sources for full-text patents.
  • Regularity of updates varies depending on the individual national patent offices.
  • Publications from major patenting authorities appear in the database within 4-6 weeks and from many countries within days of publication.
  • Click on “Save Full document” in the horizontal toolbar and follow the instructions.
  • If you see “Document too large”, save the document one page at a time.

You can view the most popular patent databases by using NUsearch [UK, China, Malaysia].

  • Choose the general category
  • Choose the subcategory called patents.

Titles of patents are often vague, may use jargon, and tend not to give away the specific content.  For this reason consider using full text searching or search abstracts or summaries and, if available, patent classification codes

Bibliographic databases

Few popular bibliographic databases include patents and those that do have incomplete coverage. Use NUsearch [UK, China, Malaysia] to access these databases.

  • Scopus: Covers a broad range of subject areas
  • BIOSIS: Includes patents in the biological and biomedical sciences.
  • SciFinder (UK only): Covers chemistry, pharmacy and chemical engineering patents and can be searched by authors, subjects, patent numbers as well as chemical structures, substructures and reactions.
  • Reaxys (UK only): Covers selected organic chemistry patents from 1869-1980 and selected English-language patents on organic chemistry, medicinal preparations, biocides, agrochemicals and dyes. It is searchable with text or chemical structures, substructure and reactions.

Databases for genetic sequences and peptide in patents (UK only)

A number of databases provide the facility to search genetic or peptide sequences in published patents. Examples include GenSeq and GenomeQuest which offer BLAST searching where sequences can be uploaded to identify matches.

In the UK, the library is able to search these and other subscription-based patent searching services. Please contact your Faculty librarian.

Obtaining printed patents

If you cannot download a patent online, the library can obtain printed copies of patents through the Interlibrary Loans service.

Patents are legal documents in their country of origin and so are published in the language of that country. Equivalents for other countries in other languages may be available.

Understanding the layout of a patent

Page one contains the Bibliographic details; inventor assignee, patent number, priority date etc.

The Specification is a written description of the invention which must specifically describe how to re-create such an invention

Claims summarise the main claims of the invention including novelty. Only the details in this section are actually protected by the patent.

Drawings may be included, if appropriate.
