According to a Patent Baristas report, the U.S. Patent and Trademark Offics ("USPTO") is proposing a rule change to require deposits when the invention involves biological material. 

Patent Baristas wrote of the proposed rule change:

The proposed rules would require:

(1) that any deposit of biological material be made before publication of a patent application; and

(2) that all restrictions on access to the deposited material imposed by the depositor be removed upon publication.

The proposed changes will provide that the public has access to biological materials referenced in the disclosure of a patent application to the same extent that access to the remainder of the disclosure is available. The public policy basis for allowing access to a referenced item is the same whether the item is another patent application or a deposited biological material.

The USPTO is currently accepting written comments to this proposed rule change through April 21, 2008.  The full text of the notice is attached.
