Types of search
The names are normalized in the index, i.e. special characters have been removed.
The name of the Inventor indicated on the first page of the Basic Patent is available in the Inventor field (since 1978).
In older documents surnames with more than 10 letters were abbreviated (e.g. Tautzenberger Tautzenber); more
recent documents (from 1985) additionally contain the full name. Both forms should be searched. From 1980, up to
8 Inventor names have been entered, before that time 3 at the most. Similarly, only 3 names are entered for Soviet
(SU) patents. Japanese inventors (from A and B publications) are entered from Derwent Week 200537. Inventors
from small countries are sometimes missing.
In older documents (up to 1985) names with umlauts are entered only with the corresponding basic vowel (e.g.
Müller Muller); more recent documents additionally contain the name with converted umlaut (Mueller). Both
forms should, as a rule, be searched. Multi-part surnames can be searched in various ways, e.g.: von Danwitz is
searchable as VONDANWITZ or as VON DANWITZ.
In DPCI and DGENE there is only a phrase index for the inventor names (/IN field), i.e. the family name must be used
together with the initial(s) or with truncation, if necessary.
20.5.2 Patent assignee
A mixed index with system interpretation is used for Patent Assignees; individual words from the name therefore
appear in one list along with the name ranked as a phrase. Usually a search by single words is assumed. (S)
proximity is used automatically:
=> S PROCTER & GAMBLE/PA
11204 PROCTER/PA
11273 GAMBLE/PA
L2 11170 PROCTER & GAMBLE/PA
((PROCTER(S)GAMBLE)/PA)
If the name is to be searched as a phrase it must be entered with quotation marks:
or
=> S "PROCTER & GAMBLE CO"/PA
L3 11059 "PROCTER & GAMBLE CO"/PA
=> S "PROCTER & GAMBLE"?/PA
L4 11169 "PROCTER & GAMBLE"?/PA
The truncation character ? must immediately precede the slash and not be included in the quotation marks.
If several entries are contained in the name field every name will be treated as one sentence ((S) proximity). Names
in a record are always in alphabetical order (may be different from the Patent Gazette).
The complete name (up to 40 letters) is entered for each Patent Assignee. Until Derwent week 9216, a maximum of
24 letters were used.
Since Derwent week 9216, all Patent Assignees (including those of the Equivalents) are added to the PA field. Prior
to this, the number of the patent assignees was limited to 4. Differing patent assignees of the Equivalents have been
added since 1976 (Derwent-Week 7648). The names of Patent Assignees (/PA) are searchable since 1970 (year of
introduction into the database).
In addition to the name of the Patent Assignee, a code is entered into the database by the database producer (into
the PACO field). (For the years 1963 to 1969, only this code is available.) The code consists of four (three up to 1970)
letters and, where appropriate, a further symbol of identification:-
