To foster research and development of the technology for patent search and retrieval by providing a forum in which researchers and practitioners from relevant communities can share their ideas, approaches, perspectives, and experiences from their work in progress.


The search and retrieval of patent and other Intellectual Property (IP) documents is important to the scientific, business, and law communities. In the past, much of the focus for patent and IP retrieval has been from the database community, and not from the Information Retrieval (IR) community. This is beginning to change as the unique semantic and syntactic characteristics of patents and other IP text documents are being addressed.

In addition to the retrieval of documents, other areas of research and development include the extraction, usage and strategic analysis of the text documents, automatic summarization, classfication, and comparisons across related documents. A particular area of internationl interest is the access of patent and IP documents in a foreign language (i.e., what is termed cross-language or translingual document retrieval).

This workshop will bring together people interested in patent retrieval and in better access to patent documents. Participants will be from different communities including patent offices, patent vendors, and information retrieval researchers. The aim is to share ideas, approaches, perspectives, and experiences from their work in progress to ensure a thorough exploration of their common ground.
