In Ford Motor Company v. Cuozzo Speed Technologies, Inc., IPR2014-01393, Paper 3 (August 28, 2014), the Board granted the petition a filing date, but required petitioner to correct its claim chart in five days, noting:

Claim charts should only be used to provide an element-by-element showing as to how the prior art teaches the limitations of a claim (e.g., citations to a prior art reference, quotations from a prior art reference). Claim charts may not include arguments, claim construction, statements of the law, or detailed explanations as to why a claim limitation is taught or rendered obvious by the prior art. A mere citation to an expert declaration (e.g., “See Ex. 1015 ¶ 29”) in a claim chart is permissible, but anything more than a mere citation is improper.
