Full Record Fields

Title

A concise descriptive English-language title written by Derwent Abstractors to highlight the content and novelty of the invention disclosed in the patent specification.

In some patents, the at @ sign may appear in a title. It is used to signify the occurrence of a chemical entity where that entity occurs as an element. For example, sodium@ indicates that sodium occurs as elemental sodium metal as opposed to where sodium occurs as a compound such as sodium chloride (common salt).

index

Patent Number(s)

The listed patent number(s) are for all members of the patent family.

The patent number is a serial number assigned to each patent document by the patent-issuing authority. Derwent inputs the two-character WIPO country code of the publishing country, followed by the serial number (up to 10 digits), and the status code indicating the document type or publication stage.

Abstract

The abstract is prepared by the Derwent Abstractor after reviewing the claims and the disclosure of the patent. Written in English, the abstract is concise, accurate, and relevant, covering the widest scope of the invention as set out in the main claim.

The abstract may include other categories such as Novelty, Detailed Description, Use, Advantage, and others depending on the selected patent.

Note: Historically, British spelling was used in Derwent Innovations Index, but American spelling is also present in the abstract (and also the titles). To ensure complete retrieval both options should be considered. For examples, see American / British terms and Derwent Abbreviations for a list of abbreviations used in both titles and abstracts.

index

Equivalent Abstract

An Equivalent Abstract is a patent that relates to the same invention and shares the same priority application date as a patent from a different issuing authority. The abstract is prepared by the Derwent Abstractor after reviewing the claims and the disclosures of the patent. In some instances, the Equivalent Abstract text may be an exact duplicate of the abstract, but it is issued from a different patent-issuing authority. Take note that any variations in the text may be due to British versus American spelling.

index

Technology Focus / Extension Abstract

A subscription to Technology Focus/Extension Abstracts is required and data must be available in the record.

Technology Focus: An optional abstract. It covers information relating to technology areas outside the core technology area of the invention. The Technology Focus Abstract is used to group information concerning how the invention is carried out into the technology area(s). By doing this, a reader can quickly identify whether a document outside the reader’s core area of technology is of interest. Information may be grouped under appropriate subheadings such as Agriculture, Biology, Biotechnology, etc.

Extension Abstract: An optional abstract that is only present when there is sufficient detail in the original patent document. It should be read in combination with the Technology Focus to make complete sense. The Extension Abstract has separate titled paragraphs, presenting the content of the patent document in a more easily understood form. It is ideal for scientists or engineers who need a detailed summary of a patent, free from legalistic jargon.

index

Show Documentation Abstract

Documentation Abstracts are written for all chemical patents that Derwent covers. They provide detailed English-language summaries of complete patent specifications. Each abstract highlights the importance of the patent.

Documentation Abstracts also extend the original abstract (which focuses on claims, uses, and advantages) to include examples, chemical reaction schemes, structures, and additional drawings and diagrams.

Did You Know ... This field only displays for users who have a subscription to Technology Focus/Extension Abstracts?

index

Drawing

If available, drawings or diagrams are selected from the patent to illustrate key components of the invention. These are available for Chemical patents from 1992 to present and for Engineering and Electrical and Electronic patents from 1988 to present.

index

Derwent Class Code(s)

The Derwent classification system is a unique system consistently applied to all patents. All technologies are covered by 20 subject areas designated as:

A to M (Chemical)
P to Q (Engineering)
S to X (Electrical & Electronic)

Each of the 20 subject areas is further subdivided into 3-character classes. The classification for A-M and S-X is applied by Derwent subject specialists. Classes for the Engineering sections P-Q are derived automatically from the International Patent Classification.

Patent Details

Patent Number: A serial number assigned to each patent document by the patent-issuing authority.

Publ. Date: The date on which the patent document is made available to the public. The format is NN MMM YYYY, where "NN" is the date, "MMM" is the month, and "YYYY" is the year.

Main IPC: The classification number of the patent according to the hierarchical classification system produced by the World Intellectual Property Organization (WIPO).

Week: Represents the week the data was entered in the product database. The format is YYYYWW, where "YYYY" is the year and "WW" is the number of the week. Example: 200120

Page Count: Represents the original patent document.

Language: An indicator shows the language of the original patent, but only where it is possible for the patent to be published in one of a number of languages. For example, European (EP) patents can be published in English, French, or German. Within the overall patent family, patents may have been issued in a variety of languages.

index

Application Details

The application number is the local filing number assigned to the patent document by the patent office. The application date or filing date is the date on which the application was filed with the patent office. The filing of a patent application is normally in the applicant's domestic patent office.

index

Further Application Details

Additional information about a patent application is placed in this data field. For example, information about the three types of continuing applications appear in this field: continuation, continuation-in-part, and division.

Continuation: Second or subsequent applications that are filed while the original parent application is pending. Continuations must claim the same invention as the original application to gain the benefit of the parent filing date.

Continuation-in-Part: Referred to as a CIP, this is the same as the continuation with the exception that some new material may be included. The disclosure of the parent is usually amplified and the CIP may claim the same or a different invention. A CIP application is accorded the benefit of the filing date of the parent application to the extent of the two applications' common subject matter. The CIP must be filed while the original parent application is pending for any disclosed material in common with the parent.

Division: If the patent office decides that an application covers too large an area to be considered as a single patent, then the application is split into one or more divisional applications. A divisional application has the same specification as the parent but claims a different invention.

index

Priority Application Information and Date

Under the right of priority provision of the Paris Convention an application may be filed in one or more contracting states or countries within 12 months of the first application. In this case the original application number becomes the priority application number. Also, the original application date becomes the priority application date.

index

Designated States

Where applicants have requested their invention be protected by means of a European or PCT application, they have to designate the states or countries in which they want the patent to take effect and pay the appropriate fees.

National: Indicates the states in which the invention are protected by a national patent.

Regional: Indicates those where protection are via a European or other regional patent.
