human: How can Microsoft Word® software be used in preparing ""clean"" and ""marked-up"" versions of an amendment in order to comply with revised 37 CFR 1.121?
assistant: In either Word 97 or Word 2000, open the document to be amended. Go to Tools and select Track Changes then Highlight Changes from the pull-down menu. Place a check mark before all three selections in the Highlight Changes dialog box (1. Track Changes while editing; 2. Highlight changes on screen; 3. Highlight changes in printed document). Under ""Options"" in the same box, select ""underline"" for inserted text, and ""strikethrough"" for deleted text. Click on ""OK."" Click on ""OK"" again to return to the document. Proceed to amend the document. The document can now be printed showing the underlining and strikethrough. This is the ""marked-up version.""
To print the ""clean version,"" go back to the Highlight Changes box under Tools and remove the check mark before ""Highlight changes in printed document."" Click ""OK"" and print the document. This is the ""clean version"" of the amended document, and does not include any markings showing deleted or added subject matter.
