In this paper, we report our approach to retrieve patent documents based on the prior art. We use the standard Information Retrieval (IR) techniques which contain indexing and retrieval processes. We use various combinations of document fields for the query formulation. Based on the evaluation summary, we achieve the best result for the combinations of invention-title, description and claims fields in terms of precision and recall.
