Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 24 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“The mere fact that the prior art could be so modified would not have made the modification obvious unless the prior art suggested the desirability of the modification.”
2 later decisions quote this exact passage · from the majority“Despite the fact that PO’S declarations and evidence are not sufficient to overcome the obviousness rejections, it is the examiner’s position that it would not have been obvious to one of ordinary skill in the art to modify Decker I to include two frustoconical bearing surfaces, in view of the teachings of Nakanishi. Examiner agrees with the PO that the teachings of Nakanishi would suggest to one of ordinary skill in the art to replace a sliding bearing structure with a roller bearing structure to provide the advantages (improved axial and radial support) taught by Nakanishi, rather than to modify the sliding bearing structure to include a pair of frustoconical surfaces. PO submitted an excerpt from Mark’s Standard Handbook for Mechanical Engineers: ROLLING FRICTION Rolling is substituted frequently for sliding friction, as in the case of wheels under vehicles, balls or rollers in bearings, rollers under skids when moving loads; frictional resistance to the rolling motion is substantially smaller than to sliding friction. This excerpt is further evidence that one of ordinary skill in the art would most likely try replacing a sliding bearing structure with a rolling bearing structure. Furthermore, this indicates that “predictable results” would be had with the rolling bearing structure (frictional resistance to the rolling motion is substantially smaller than to sliding friction). Replacing the sliding arrangement with roller arrangement (PO shows such an arrangement on page 6”
