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 9 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“The portion of the italicized clause of claim 18, supra, which reads ‘to thereby induce a zeta potential of the same charged sign as the ink particles and which differs from that of similarly charged particles of the material by a factor of at least 4,’ at first glance, appears to be functional in the sense that it might be construed that the sole purpose of the phrase is to recite a result which is desired to be obtained from the addition of a water soluble salt yielding an ion having a valence of at least 4. However, it is our opinion that this phrase sets forth much more, and is therefore not a mere statement of desired result. When the italicized portion of the claim, noted above, is read in its proper context in the claim, it must be considered to be a limitation which is required, as a result of the step of adding the salt, to successfully carry out the process. This phrase is as much a limitation of the claim as the recitation of the salt yielding an ion having a valency of at least 4 since it recites an essential characteristic of the solution which must be obtained as a result of adding the salt. In other words, the above-quoted phrase does not merely set forth a desired result per se, but couples with the desired result a physical characteristic which is deemed necessary by appellants for the successful performance of their process.”
