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 .
Response to Amendment
The amendment filed by the Applicant on 2/17/26 is acknowledged, however they are moot in light of new grounds of rejection for the amended claims.
Claim Objection
Claim 8 is objected to because of the following informalities:
In claim 8, the limitation of “an included angle between the first inclined surface and the body surface is greater than zero degrees” is unclear language. As the entire surface of the body is considered as the body surface. It is not clear what is the body surface and where it is located.
Further, in claim 8, the limitation of body surface is not recited in the claim that claim 8 depends on (that is, claim 1). Appropriate correction is needed. For purposes of examination, it is considered as “light guide body surface”.
