This report presents the work carried out at NLE Lab for the CLEF-IP 2009 competition. We adapted the JIRS passage retrieval system for this task, with the objective to exploit the stylistic characteristics of the patents. Since JIRS was developed for the Question Answering task and this is the first time its model was used to compare entire documents, we had to carry out some transformations on the patent documents. The obtained results are not good and show that the modifications adopted in order to use JIRS represented a wrong choice, compromising the performance of the retrieval system.
