A Request for Reconsideration is essentially a response to a Final Office Action that includes arguments and, in some cases, amendments. When you have new evidence for the examining attorney to consider, this option makes more sense. Consider amending your identification of goods to remove certain items that overlap with or relate to goods in cited registrations, for example. If you're dealing with a purely descriptive refusal, you might discover some new evidence demonstrating why consumers would not consider your mark to be descriptive of a feature of your product or service.
You should not file a Request for Reconsideration that simply repeats the same arguments. A response that simply rehashes previously made arguments while providing no new information is doomed to fail.
