Sets forth procedures with respect to the joinder of parties and discovery of evidence.

Directs each party to be responsible for the costs of producing core documentary evidence within the possession, custody, or control of that party.

Defines "core documentary evidence" as documents that:

relate to the conception, reduction to practice, and application for the asserted patent;

are sufficient to show the technical operation of the instrumentality identified in the complaint as infringing the asserted patent;

relate to potentially invalidating prior art;

relate to previous licensing or conveyances of the asserted patent;

are sufficient to show revenue attributable to any claimed invention;

are sufficient to show the organizational ownership and structure of each party, including identification of any person with a financial interest in the asserted patent;

relate to awareness of the asserted patent or claim, or the infringement, before the action was filed; and

are sufficient to show any marking, lack of marking, or notice of the asserted patent provided to the accused infringer.

Excludes from the definition of core documentary evidence any computer code or electronic communication, such as e-mail, text messages, instant messaging, and other forms of electronic communication, unless the court finds good cause.

Permits additional discovery under specified conditions if the party seeking such additional discovery bears the costs, including reasonable attorney's fees.

Directs courts to award to the prevailing party reasonable costs and expenses, including attorney's fees, unless: (1) the position and conduct of the non-prevailing party were objectively reasonable and substantially justified, or (2) exceptional circumstances make such an award unjust. Allows the court, if the non-prevailing party is unable to pay such costs and expenses, to make the costs and expenses recoverable against interested parties.
