Claims Must Be Amended to Remove from Appeal Consideration
Note:
An appellant must submit an amendment to cancel claims from the application if they wish to remove them from appeal consideration. Failure to argue or present evidence for certain claim rejections results in automatic sustenance of those rejections.

If an appellant wishes to remove claims from consideration on appeal, the appellant must submit an amendment to cancel the claims from the application. See 37 CFR 41.31(c) and 41.33. An appellant may, of course, choose not to present arguments or rely upon particular evidence as to certain claim rejections; however, such arguments and evidence are waived for purposes of the appeal and the Board may summarily sustain any grounds of rejections not argued. See MPEP §§ 1205.02 and 1214.05.
