Claim: “… the main bearing consists solely of one single-row rolling bearing (excluding cross-roller bearings), or …”
The description in Exhibit Ko 1 does not establish what type of bearing the “bearing” in the primary reference is.
⇒ Not specifically identified.
*“Addition versus substitution”: If a particular configuration is found to be disclosed in the primary reference, the obviousness of “substitution” becomes the issue, and the hurdle for denying inventive step is high. If a particular configuration is found not to be disclosed in the primary reference, the obviousness of “addition” becomes the issue, so the hurdle for denying inventive step is lower.
“As bearings, ‘single-row rolling bearings’ other than cross-roller bearings and ‘plain bearings’ are well-known configurations of machine elements.”
⇒ Inventive step denied.
Translator’s notes (editorial)
Source wording includes an apparent typo in the sentence contrasting addition and substitution; its evident meaning is translated without changing the underlying proposition.
