Following up on my earlier post dated December 28, 2012, the proposed local patent rules at the United States District Courts for the Eastern and Southern Districts of New York are now in effect as of April 8, 2013.  The local patent rules for the Eastern District of New York (.pdf) and the Southern District of New York (.pdf) are much less detailed than local patent rules adopted by other courts.  For example, the Eastern and Southern Districts of New York only require the following for infringement contentions, “… a party claiming patent infringement must serve on all parties a ‘Disclosure of Asserted Claims and Infringement Contentions,’ which identifies for each opposing party, each claim of each patent-in-suit that is allegedly infringed and each product or process of each opposing party of which the party claiming infringement is aware that allegedly infringes each identified claim.”  (L.P.R. 6)  This minimal disclosure stands in stark contrast to other courts such as the Northern District of California which require much more detail for infringement contentions.
