Our Policies on Coverage Map Information

Note that our coverage information is obtained from search systems' published coverage information. We cannot guarantee the accuracy and completeness of this information. Systems are chosen from a selection of known patent search providers; we cannot ensure that all search systems are represented here. Systems which claim to receive coverage from the INPADOC (also called DOCDB) file are automatically listed for all countries covered by that file. We cannot guarantee the accuracy of national patent office website links.


How Do We Assign a Coverage Level?

Coverage is indicated for the greatest level of text available, in the following order:

Full > Partial > Bibliographic

The greatest level of searchable text is recorded for the entire date range covered by the system. For example, a collection for which full text exists for the first twenty years, but which only contains bibliographic coverage for the next forty years, is still represented as a full text collection on our maps.

Also note that only searchable data is represented in our coverage map. A system which provides full document text, but only allows users to search within the electronic titles and abstracts of the collection, is labeled as partial text rather than full text.

Finally, note that coverage does not have to be in the English language for the collection to be represented on the coverage map. Full text, partial text, and bibliographic coverage designations are given irrespective of the languages of publication used in the collection.


Definitions of Coverage Levels

Full text coverage means searchable, electronic text including all major sections of the patent document (title, abstract, description and examples, claims).

Partial text coverage means any searchable, electronic text of a patent document beyond bibliographic data and title. Any system which includes the INPADOC file will have many partial text collections shown on our maps, as the INPADOC file contains at least some abstract content for many of the country collections within it. In addition, Derwent World Patents Index abstracts are also shown as partial text in Intellogist maps, even though they are not part of the original document text.

Bibliographic coverage means searchable, electronic document metadata, possibly including document number, publication, application and priority data, author, assignee/applicant, inventor, and/or an original language or English translation of a document title. Original, hand translated, and machine translated document abstracts are all considered partial text. In addition, Derwent abstracts are considered partial text.

The following additional categories are used in the Interactive Coverage Map only:

Chemical Structure Indexing coverage is only recorded for three major sources which index chemical patent documents by adding searchable chemical structure data. These are the MMS system, and the CAplus and MARPAT files on STN. Other chemical structure searchable files which may contain patent documents from these countries are not recorded under this heading.

Image coverage means availability of facsimile document images for viewing and/or downloading. Although PDFs are most common, images may be in any typical image format to be considered as coverage. Systems which host images through a link to a third party vendor are identified with an asterisk (*) . For example, Minesoft's PatBase system may not offer downloadable PDFs for Slovakian patent documents; however, the system may make them available to users by linking to the EPO's image database on esp@cenet.
