Association of Research Libraries (ARL)
The ARL is a not-for-profit membership organization comprising the leading research libraries in North America. Its mission is to shape and influence forces affecting the future of research libraries in the process of scholarly communication. There are currently 120 member institutions.
An examined German patent application (second publication) now eliminated (see Offenlegungsschrift and Patentschrift).
Writer of an article, chapter or other complete work. Some articles, proceedings, or books have multiple authors. In such cases, the first author specified in the reference may be called the primary author or the senior author. The names of the authors following that of the primary author are referred to as the secondary or co-authors. Corporations, government agencies and associations may also be listed as authors of a work.
ISI indexes all source authors. Primary and secondary authors of a source article are searchable in the print and electronic products. ISI also indexes all cited authors. The first cited author in each reference is searchable in all products. Unique to the Web of Science® is the ability to search on secondary authors in the cited reference field.
Baselines are measures of cumulative citation frequency across all Derwent Section classes. Baselines are able to show trends (both upward and downward) within a particular patent family. Derwent Patent Indicators offers two sets of baselines: Derwent section averages and percentiles.
See Basic Patent.
The first member of a Derwent patent family. This may or may not be the first published patent (which is usually the first to be documented by services such as Derwent World Patents Index).
A major structure and factual database in organic chemistry.
When two papers cite one or more of the same articles, they are said to be "bibliographically coupled". The more articles they cite in common, the stronger their subject relationship to one another.
bibliographic management tool
Software that enables the end-user to arrange and store bibliographic references on a customized basis in an electronic format.
ISI offers three bibliographic software packages: Reference Manager®, EndNote® and Pro-Cite®.
Standard entry that refers the end user to an original source of information referenced or cited by an author in the main body of the text. A bibliographic reference usually includes title of article, chapter or complete work, author, source, and where appropriate, the volume number, issue number and pagination.
ISI indexes these bibliographic references or citations. The use of bibliographic references demonstrates the value of a specific work across a variety of journals and disciplines and through time. (See cited reference searching). By tracking the frequency with which a specific bibliographic reference appears across a wide variety of journals, one is better able to evaluate the importance of that work to a multidisciplinary audience.
A listing of references to source material on a given topic appearing at the end of an article, chapter or other complete work. References are usually listed alphabetically by author name.
Study of the quantitative data of the publication patterns of individual articles, journals, and books in order to analyze trends and make comparisons within a body of literature.
See also: Scientometrics
Any serial or periodical with a frequency of publication of every two years.

Five-digit codes that represent taxonomic groups above the genus level. Associated with each Biosystematic Code is a Biosystematic Heading. Biosystematic headings are also known as super taxa.
See Biosystematic Codes.
A method of combining concepts in a search which allows the searcher to narrow or broaden the focus of a search. Boolean logic uses three logical commands (sometimes called "operators"). These operators are the words AND, OR, and NOT.
The OR command is used to expand or broaden search results to include synonyms and related terms.
Example: violence or conflict or aggression. This search string would retrieve any record that held any of those three words.
The AND command is used to narrow or restrict search results.
Example: violence and conflict and aggression. This search string would retrieve any record that contained all of those three words. Note, however, that this search would not retrieve any record that had only two of the three terms.
The NOT command is used to further restrict search results.
Example: television and broadcasting not video. In this instance the search string would retrieve records that had both the terms "television" and "broadcasting" but would eliminate those records if they also contained the word "video".
The addition of parentheses enables the searcher to specify which segment of the search string is to be evaluated first.
Example: television and (violence or aggression). In this instance, the search engine will look first for items that contain either of the terms "violence" or "aggression". It will then narrow down those search results even further to contain only the records that have the word television as well as either of the other two terms.
The concept that the most significant articles to any given field of investigation are found within a relatively small group of journal publications. According to S.C. Bradford, the essential core of journal literature for the bulk of scientific research is to be found in a group of approximately 2000 journals. Different sets of journals from this basic core will have a greater relevance to one topic, and weaker relevance to several other topics.
Clinical Unknown Phase from IDdb. In clinical development, but the phase is unknown.
Phase I (IDdb). Initial toxicity testing in healthy volunteers (except for drugs that are potential treatments for life-threatening diseases such as cancer and HIV, which go straight into subjects suffering from the target disease).
Phase II (IDdb). Small-scale testing in the target population, to assess therapeutic effects and to establish dose levels for phase III trials.
Phase III (IDdb). Large-scale trials in patients, usually at several centres, double-blind and randomised. May also be compared to other agents.

citation - Derwent
Citations may be made by the examiner or author. They comprise a list of references that are believed to be relevant prior art and which may have contributed to the "narrowing" of the original application. The examiner can also cite references from technical journals, textbooks, handbooks and sources.
citation - ISI
A citation is a reference published with a scholarly journal article. ISI includes all these citations in it's citation databases, and this unique compilation makes possible cited reference searching. (See also bibliographic reference.)
Citation counts are a formal acknowledgement of intellectual debt to earlier patants and previously-published scientific research papers. They are an important indicator of how new patents are linked to earlier patents and scientific papers.
Citation counts are recognized as units of influence or impact on technological development. That is, a patent builds on earlier patents, and thus advances the technology. By tabulating and aggregating citation counts, Derwent Patent Indicators offers a unique perspective for patent evaluation and comparison.
A citation index is a bibliographic tool in print or electronic format that lists all referenced or cited source items published in a given time span. The tool is a useful method for tracking the historical development -- backwards and forwards in time -- of an idea or given topic within the literature published in a wide selection of journal titles. What distinguishes it from other indexes is that it includes all the cited references (footnotes or bibliographies) published with each article it covers. For a more detailed explanation, please see the essay: The Concept of Citation Indexing: A Unique and Innovative Tool for Navigating the Research Literature
Cited half-life is a measurement used to estimate the impact of a journal. It is the number of years, going back from the current year, that account for 50% of the total citations received by the cited journal in the current year.
ISI developed this calculation to provide an indicator as to the long-term value of source items in a single journal publication. The cited half life calculation appears only in the Journal Citation Reports® (JCR®)
ISI indexes extensive information about each article indexed in its products including the article's cited reference list (often called its bibliography). This information allows a user to search the citation indexes for articles that cite a known author or work.
See also: cited reference searching
Cited reference searching, unique to ISI, lets you use a given work as if it were a subject term to identify more recent articles on the same topic. For example, you can find all works that reference articles published by A. Williamson in 1995 in the Journal of Neurophysiology (J Neurophysiol). This type of searching often locates relevant articles that cannot be retrieved through traditional subject-author searching.
The number of journal publication years, going back from the current year, that account for 50% of the total citations given by the citing journal in the current year.
ISI developed this calculation to provide an indicator of the subtle changes in scope of a publication over the course of time. Evaluation of this factor can provide information on the cross-disciplinary nature of research in a specific field of interest. For additional information on measure, see the essay: Expected Citation Rates, Half-Life, and Impact Ratios: Comparing Apples to Apples in Evaluation Research

continuation (see Continuing Applications)
Applicable mainly in the US, continuations are second or subsequent applications which are subsequently 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 (see Continuing Applications)
Generally referred to as a 'C.I.P' this is essentially 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 C.I.P may claim the same or a different invention. A C.I.P application is accorded the benefit of the filing date of the parent application to the extent of the two applications' common subject matter. The C.I.P must be filed while the original parent application is pending for any disclosed material in common with the parent.
There are three types of continuing applications: division, continuation and continuation-in-part
The legal right granted to an author, editor or publisher of an article, chapter or complete work. Copyright applies to intellectual property in a variety of artistic fields and attempts to be format-neutral.
ISI has a long-standing reputation for copyright compliance and has worked tirelessly to address the concerns of intellectual property holders in the electronic environment. The ISI Document Solution(SM) (IDS) makes sure that all articles provided to customers have appropriate copyright clearance through payment of an appropriate fee to the rights holder.
The fee paid to the holder of the copyright when a reproduction of the article, chapter or complete work is made by or for an end user. The actual dollar amount is set by the individual publisher; typically, it is assessed when clients order individual copies of articles from any document vendor such as the ISI Document Solution (IDS) service provided by ISI.

A lawsuit filed to determine where the plaintiff is in doubt as to his legal rights. With respect to patents, this is a lawsuit filed by someone against the patent holder asking the court to declare that the inventors patent is invalid or that the plaintiff is not infringing the patent. The possibility of such a lawsuit is a source of concern for poorly financed patent holders who must be careful lest something they do be seen as accusing others of infringement requiring them to defend against a lawsuit often at a distant location and at great expense.

Derwent Classification Codes
Derwent classifies patents using a system designed for all technologies. This is consistently applied to all patents by subject experts enabling effective and precise searching in a particular area of technology.
Patents are initially divided into 3 main groups: Chemical, Electrical and Electronic, and Mechanical Engineering. Each main group is further divided into sections and then each section into classes.
Derwent Chemical Patents Index.
Derwent Patent Indicators categorizes patents by Derwent Section.
In some cases the title of patent specifications is intentionally uninformative since the applicant does not wish anyone to know the details of the filing before it has been examined. Derwent writes a descriptive title in 2 parts: 1) the invention and its application, and 2) a description of its novelty - its advantages and what makes it new.
Derwent also computer generates a list of standardised terms - called Title Terms - which will also be searchable in Derwent Innovations Index as part of the Topic Search. These are additionally assigned words that are the standard forms of title words (cancer for cancerous, etc.).

division (see continuing applications)
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.
The first public disclosure of details of an invention. This may be:
· deliberately revealed outside the patent system to make the invention unpatentable, or
· what is described in a patent application.
In some countries, such as the USA, this refers to where an application has been resolved by being withdrawn, rejected or granted. It can also have the connotation of being rejected only.
Doctrine of Equivalents
A doctrine which says that even if a patent claim does not literally read on a possibly infringing device, it can be read more broadly providing it does not read on the prior art. It is designed to allow the inventor to assert a patent where the differences between the inventor's and an infringer's product are not substantial.

See Fragmentation codes
BCE Chemical Fragmentation Codes. Also known as Chemical Indexing or Frag Codes. This is a system which uses codes to designate presence or absence of features present in indexed compounds. Most codes relate to parts of the chemical structure; some are non-structural, for activity, role and/or application of compound in the patent. Currently applied to patents in Derwent sections BCE. Dates back to the very beginning of DWPI (1963).
Interval at which issues of a periodical or serial are published. Most publishers indicate the frequency of a journal to subscribers so that the subscriber can know in advance how often to expect delivery of an issue.
The publisher's demonstrated ability to maintain frequency is one of the criteria for inclusion of a journal in the ISI databases. For a more complete explanation of these criteria, please see essay: The ISI Database: The Journal Selection Process

Gene Therapy Database. Abstracts from Patents and Literature papers. Available on CD-ROM.
A keyword (or code) that is used to describe another keyword (or code) more generally (see Keyword).
highly cited patent
Derwent Patent Indicators specifically indetifies those patents that are frequently cited. Generally, a highly cited patent is in the top percentile of the rankings by times cited. Only a relatively small number of patents received this amount of attention. In many instances, a highly cited patent may contain a significant advancement. These citation links can reveal whether different sectors of technology are building upon each other or progressing rapidly.
In Derwent Patent Indicators, the time period for highly cited patents is the last 10 years. That is, the product goes back 10 years to retrieve highly cited patents.
Derwent Patent Indicators specifically identifies those patents that are frequently cited within a short period. Generally, a hot patent receives attention shortly after it's publication data and may contain a new advancement.
In Derwent Patent Indicators, hot patents are identified based on the most recent quarterly citation count of patent families with PAN years going back four years. That is, the product goes back three years, plus a partial fourth year, to retrieve hot patents.
The Investigational Drugs database. A daily-updated, industry-wide competitor intelligence and R&D monitoring service. The IDdb provides validated, integrated and evaluated information on all aspects of drug development, from first patent application to launch or discontinuation. Importantly, all IDdb records are continuously updated as new information is received.
The ISI Document Solution(SM)
Questel.Orbit communications software designed for accessing all online hosts, but especially Questel.Orbit.
The average number of times that an article published in a specific year within a specific journal is cited over the course of that same year.
This calculation, published in the Journal Citation Reports, is one developed by ISI as an indicator of the speed with which citations to a specific journal appear in the published literature. Such information is useful in determining which journals are publishing in emerging areas of research
The number of current citations to articles published in a specific journal in a two year period divided by the total number of articles published in the same journal in the corresponding two year period.
ISI stresses that a journal's impact factor is a meaningful indicator only when considered in the context of similar journals covering a single field of investigation or subject discipline. For more information on this, please refer to the essays: The Impact Factor and Using the Impact Factor
Implicit citations are of three sorts, illustrations, music examples and general implicit citations.
Illustrations are defined as full representations of a work of art or craft that appear in journal articles especially (but not limited to) those in art and architecture journals. ISI inserts a reference to the artist and the work and marks it as an illustration.
Music examples are bars of musical notation reproduced in a journal article, usually to demonstrate some musical concept; these are generally found in musicology or music pedagogy journals. When these examples appear, ISI references the composer and the work of music and marks it as a music example.
General implicit citations are those that ISI creates based on an implied reference in the title or text of an article; this occurs if, for example, the author assumes a shared knowledge on the part of the reader and does not formally cite a work. In this case, ISI makes a reference to the author and work and marks it as an implicit citation.
Implicit citations are an enhancement found in the Arts & Humanities Citation Index®.
Alphabetized list of names, places, and topics treated in a printed work which gives the page number(s) on which each topic is discussed. Usually located at the end of a book, or in the last volume of a multi-volume work.
information management tools
Software that enables the end-user to arrange and store bibliographic references on a customized basis in an electronic format.
ISI offers three bibliographic software packages: Reference Manager®, EndNote® and Pro-Cite®.
To make, use or sell the patented item or process within the country covered by the patent, without permission or licence from the patentee.
1. Encroach or trespass on the rights of others, usually involving intellectual property. 2. To make, use or sell the patented item or process within the country covered by the patent without permission or license from the patentee. A device infringes on a patent if the claims of a valid patent read on that device.

Intellectual property refers to creations — including inventions, artistic works, names and designs — that are legally protected. Intellectual property includes patents, copyrights, trademarks and trade secrets.
A procedure declared by the patent office when it appears that two or more people made the same invention at roughly the same time. It is an expensive, lengthy court-like proceeding designed to determine who was the first true inventor. About 0.1% of patents are involved in interference proceedings.
International Patent Classification
This system of classifying patents according to technology groups has evolved under the auspices of several countries and the WIPO. The system is under continual revision to take into account new technologies. It is a hierarchical system using letters and codes. There are eight sections that are broken down into classes and subclasses.
Documents are classified according to two principles: 1) when they relate to similar solutions to the same technical problem (classification by function), and 2) grouped together according to the industrial art in which the problem arises (classification by application).
Inventor names are recorded for all patents. These appear in the standard last name-initial(s) format.
International Patent Classification. An internationally recognised classification system assigned by patent examiners.
International Standard Book Number. Unique ten-digit publisher's I.D. number for a specific edition of a book. Usually printed on the reverse side of the title page, and on the back of the dust jacket, or cover of a book published in softcover.
Institute for Scientific Information. A Thomson business, now part of Thomson Scientific

International Standard Serial Number. Unique eight-digit number which identifies a specific serial title.
All the copies of a specific publication (usually a serial or periodical) with an assigned number and/or date, such as Issue #1, Spring 2002. Issues are published in consecutive order according to this number or date for the sake of chronological organization of information.
Industry & Technology Patents Profile
Commercial wing of the Japanese Patent Office
A serial or periodical usually devoted to a specific field or subset of scholarly knowledge. A few scholarly journals (such as Science or Nature) are multidisciplinary in their approach to a broad range of inter-related fields of investigation. An article appearing in a scholarly journal is composed of different elements including an author abstract and a bibliography of works cited or referenced in the article.
Derwent Journal of Synthetic Methods
Japan Science and Technology Corporation. See STN.
Terms supplied by the author(s) as part of the paper which may act as descriptive terms for inclusion in a search strategy that is intended to retrieve an article. Keywords are frequently included in the header information of a published journal article. These keywords are contained in the ISI record for each article and are searchable. In addition, ISI generates KeyWords Plus for many articles.
NOTE: A keyword search does not take into account the meaning of terms used for searching. If a keyword has more than one meaning, irrelevant records ("false drops") may be retrieved.
KeyWords Plus are words or phrases that frequently appear in the titles of an article's references, but do not appear in the title of the article itself. KeyWords Plus may be present for articles that have no author keywords, and may include important terms not listed among the author keywords.
The letter, often with a further number, indicating the level of publication of a patent. For example DE-A1 is the German Offenlegungsschrift (application laid open for public inspection) while a DE-C1 is the German Patentschrift (first publication of the granted patent).

The Paris Convention was established March 20 1883, effective July 7 1884, and amended June 2 1934 and July 14 1967. Signatories to the Paris Convention are allowed one year from first filing their patent application (usually in their own country) in which to make further applications in member countries and claim the original priority date.
A patent is a documentthat defines the right by law for inventors and assignees to make use of and exploit their inventions for a limited period of time.
Definitions vary from country to country as to what comprises a patentable invention. The granting of a patent in any particular country gives the owner of the patent with the legal authority to exclude others from making, using, or selling the claimed invention in that country without their consent, for a fixed period of time.
This authority does not extend to any other country. A patent needs to be obtained in each country where protection is sought.
Patents are a form of intellectual property protection. They should not be confused with trademarks, servicemarks, and copyrighted material, which are other forms of protection of intellectual property.
A document submitted by an inventor to request he be issued a patent. It consists of the elements of a patent but will likely be modified during patent prosecution.
The ability of an invention to satisfy the legal requirements for obtaining a patent, including novelty. In some countries certain types of inventions, e.g. computer software and plants, may be unpatentable.
The individual(s) or corporate body to whom all of limited rights of the patent are legally transferred.
The assignee is usually the company that owns the rights to the patented invention. These can be individuals, but normally they are companies. Derwent assigns a standard 4-digit code to patent producing companies. By using the 4-digit code one can retrieve the worldwide holdings of a company as well as its subsidiaries and related companies. They link companies with different names through these codes.
patent assignee code
To standardize company names, Derwent assigns a unique four-letter code to approximately 21,000 companies worldwide. Use of these codes retrieves subsidiaries and related holdings of the company. Other companies and individual patent assignees are given a non-standard four-letter code, which is not unique. These appear as:
· ABCD - Nonstandard,
· ABCD - Soviet Institute, or
· ABCD - Individual.
Patentee names were limited to a maximum of four with up to 40 characters with no restriction on the total number of names. The name may be shortened or abbreviated to fit the restriction, for example: INT for International.
The P.C.T. was signed in Washington D.C. on June 19 1970 and entered into force January 24 1978. It was amended with effective dates of May 3 1984 and January 1 1985. There are currently 96 signatories to this treaty. Contracting states may file an international application designating member states. If an applicant wants to press for grant in any of their designated states the patent application is m oved to the national phase(s) but may carry the P.C.T. priority filing date.
A patent family is a set of individual patents granted by various countries. Think of a parent family as all the equivalent patent applications corresponding to a single invention, covering different geographical regions.
As applications are made for patents of an invention in countries around the world, Derwent links these patents together in a patent family structure. Derwent then tracks the development of the patents, indexing all updates received from the various international patent authorities.
A patent number is a unique identifier of a patent (for example, EP178925 and US4796266 are valid patent numbers).
Patent numbers are 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 serail number (up to 10 characters), and a status code indicating the document type or publication stage.
A granted German patent application.
A description of the invention, including a description of the monopoly claimed. This may be published several times, first as the applicant wrote it, then after a patent examiner has amended it, and then finally after any objections from third parties have been taken into account.
patent status codes
These are sometimes referred to as Kind Codes. For most patent issuing authorities more than one version of the patent specification is issued. As these sequential documents sometimes keep the same serial number, they are assigned a patent kind code or status code. These codes are a combination of the patent status and the sequence of publication - status being examined or unexamined, sequence meaning the first or second publication within the status.
Any country or organization with the authority and the power to issue patents.
Patent-to-patent citations reveal whether different sectors of technology are building upon each other. They also provide an indicator of the performance of a particular patent assignee in both public and private sectors. A synthesis of patent-to-patent citation information can lead to indicators of technological development.
Portable Document Format
The process by which an article is evaluated for acceptance or rejection for publication in a scholarly journal. Only a scientist's peers in a particular field of study are considered to be valid critics of the worthiness of the manuscript for publication.
The period in which the patent office has not yet decided whether to reject or to grant a patent application, and it has not yet been withdrawn.
The initial study of an application by an official in the patent office to check that the specification is properly arranged and for preparing search reports.

Primary Accession Number (PAN)
A unique identification number assigned by Derwent to the first patent in each patent family, and therefore to the database record created for that family. The format of each number is a four-digit year, followed by a hyphen and a six-digit accession number in YYYY-NNNNNN format (for example, 1999-468964).
Previously used or published technology that may be referred to in a patent application or an examination report.
During the initial stages of development of a new technology a company will perform extensive searches of patent and non-patent databases to find out everything that has been previously published which pertains to the technology or "art". This is referred to as prior art searching. This is needed to determine the novelty of the invention and to be certain that the invention does not infringe upon the rights of another inventor.
Under the right of the 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 date.
The initial date of filing of a patent application, normally in the applicant's domestic patent office. This date is used to help determine the novelty of an invention.
Documents, including patents of most countries that are printed (published) in and are actually or presumptively available to the public.
publication year - Derwent
The patent publication year is the date on which the patent document is made available to the public. The format is NN MMM YYYY (for example, 22 Jun 1999).
Any publication that has a frequency of publication of four times per year, generally conforming to the four seasons (spring, summer, fall, winter) of the year.

For Current Contents, the ISI current awareness database, ISI scans and images each source publication and reconstructs the table of contents from the various records that it has processed from that particular issue or volume. This step is added to the process because the tables of contents from most source publications will not identify all of the document types that ISI deems significant within the publication.
ISI also provides bibliographic information as well as tables of contents for recently released book titles. Current Book Contents® focuses on various disciplines within the life sciences.
Common names of broad groups of organisms and microorganisms mentioned in the source document.

This number appears as a part of the full record in the Web of Science.
These are terms added to the source title that clarify, add meaning or supply search access points that would otherwise not exist.
ISI indexers review an article title and assess the words for their ease of retrieval and their overall meaningfulness. If title words do not fit these criteria or if the title is obscure and/or ambiguous, the indexer will read the article to find its focus and add appropriate terms to the article title. In the Arts & Humanities Citation Index, this is usually indicated by putting parentheses around the enhancement terms.
NOTE: This is only done for the Arts & Humanities Citation Index. Title enhancements are a unique feature of this index.
