From todays' Federal Register:
The USPTO conducted a roundtable to determine whether or not there is support in the patent community and/or the public sector for the adoption of some type of deferral of examination . . . The USPTO also invited written comments by any member of the public on the issues raised at the roundtable, or on any issue pertaining to deferral of examination . . . The USPTO Webcast the roundtable and a video recording of the roundtable is available on the USPTO’s Internet Web site. The USPTO is extending the comment period to provide interested members of the public with an additional opportunity to view the Webcast before submitting comments to the USPTO.
