Claim Comment
Claims 2-4 and 7-10 recite limitations toward the optical glass using the separator “and/or”. This is read such that as long as one of the recited limitations is meet, the claim is considered anticipated or rendered obvious.
Claims 5 and 6 recite limitations toward the optical glass using the claim language “wherein the components of the optical glass satisfy one or more of the following molar ratios”. This is read such that as long as one of the recited molar ratios is meet, the claim is considered anticipated or rendered obvious.
