In this article, we present ongoing work on an advanced patent processing service
PATExpert. The central assumption underlying PATExpert is that in order to meet the needs
of the users of patent processing services, recourse must be made to the content of patent
material. We introduce a content representation schema for patent documentation and
sketch the design of techniques that facilitate the integration of this schema into the patent
processing cycle. Two types of techniques are discussed. Techniques of the first type …

In this article, we present an operational prototype of a workbench for intelligent patent
document analysis and summarization that has been developed in the context of the R&D
project TOPAS, partially funded by the European Commission. The workbench uses the
GATE environment as infrastructure for document representation and algorithm integration. It
contains, apart from several preprocessing tools, five modules for the individual aspects of
patent analysis (entity recognition, lexical chain identification, invention composition …
