(b) Exchange of Preliminary Claim Constructions and Extrinsic Evidence, and Conference of the Parties

(1) Not later than fourteen (14) days after the exchange of the proposed terms for construction pursuant to SPR 6.1(a), the parties shall simultaneously exchange proposed constructions of each term identified by either party for claim construction. Each such "Preliminary Claim Construction" shall also, for each term which any party contends is governed by 35 U.S.C. § 112(f), identify the function of that term and the structure(s), act(s), or material(s) corresponding to that term's function;

(2) At the same time the parties exchange their respective Preliminary Claim Constructions, each party shall also identify all references from the specification or prosecution history that support its proposed construction and designate any supporting extrinsic evidence including, without limitation, dictionary definitions, citations to learned treatises and prior art, and testimony of percipient and expert witnesses. Extrinsic evidence shall be identified by production number or by producing a copy if not previously produced. With respect to any supporting witness, percipient or expert, the identifying party shall also provide a description of the substance of that witness' proposed testimony that includes a listing of any opinions to be rendered in connection with claim construction;

(3) Not later than fourteen (14) days after the exchange of the Preliminary Claim Constructions, the parties shall thereafter meet and confer for the purposes of limiting the terms in dispute by narrowing or resolving differences and facilitating the ultimate preparation of a Joint Claim Construction and Prehearing Statement. The parties shall also jointly identify no more than ten (10) disputed terms per patent in suit, for inclusion in the Joint Claim Construction and Prehearing Statement. In the event of a dispute as to which terms to include in the Joint Claim Construction and Prehearing Statement, each side shall be presumptively limited to five (5) disputed terms per patent in suit, which limit can only be altered by leave of court.
