In Microsoft Corporation v. Cellular Communications Equipment LLC, IPR2015-00011, Paper 3, (October 17, 2014), the Board gave Microsoft’s petition a filing date but required Microsoft to re-file the Petition because it contained singled spacing. In a clear breach of double spacing etiquette, the identification of claims challenged on pages 3-4 and a footnote on page 50 were single spaced. Don’t interfere with the orderly review of patents — double space everything!
