Disclosure Requirements for Patent Cases for Declaratory Judgment of Invalidity

W.D. Tenn. Local Rule 3.9

In all cases in which a party files a complaint or other pleading seeking declaratory judgment that a patent is invalid, LPR 3.1-3.4 shall not apply unless and until a claim for patent infringement is made by a party in the Initial Response. If the defendant does not assert a claim for patent infringement in its Initial Response, the party seeking declaratory judgment of invalidity shall make its required disclosures under LPR 3.5 and 3.6 within 30 days after the Initial Response is filed. All other deadlines and requirements under the Local Patent Rules shall remain the same. This Rule shall not apply to cases in which a request for a declaratory judgment that a patent is invalid is filed in response to a complaint for infringement of the same patent.
