Where a subpoena commands a person to produce documents for inspection or copying, the subpoenaed person may object to it. The objection must be in writing, and delivered to the person or attorney designated in the subpoena as being responsible for issuing it. The objection must be made within 14 days after receiving the subpoena. However, if the subpoena gives fewer than 14 days for compliance, then at any time before the time set by the subpoena for compliance. Fed. R. Civ. P. 45(c)(2)(B).
