In all cases in which a party files a complaint or other pleading seeking a declaratory judgment that a patent is not infringed or is invalid, Loc. Pat.

Pat. R. 3.3 and produce or make available for inspection and copying the documents described in Loc. Pat. R. 3.4. (b) Inapplicability of Rule. Loc. Pat. R. 3.6 shall not apply to cases in which a request for a declaratory judgment that a patent is not infringed or invalid is filed in response to a complaint for infringement of the same patent, in which case the provisions of Loc. Pat. R. 3.3 shall govern.
