Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Objections
Claims 5 and 16 are objected to because of the following informalities:
Both claim 5 and claim 16 include the phrase "the sub-faces comprise...". However, there is no introduction of an element "sub-faces" in any claims from which these two depend.
Appropriate correction is required.
