*The cited reference contains no limitation.
⇒ Evidence from the filing date shows disclosure of non-light-transmitting ink as well.
“At the filing date … light-transmitting … CMY inks were widely used …; a person skilled in the art would readily have understood Exhibit Ko 4, which contains no statement or suggestion limiting it to non-light-transmitting … ink, as compatible with light-transmitting … ink.”
(Excerpt from the court's reasoning)
…Since CMY inks having light-transmitting properties (transparency) were widely used in solvent inkjet printing at the filing date, even if non-light-transmitting inks were sometimes used at that date, a person skilled in the art encountering Exhibit Ko 4—which is compatible with solvent inkjet printing and …contains no statement or suggestion limiting solvent inkjet printing to non-light-transmitting inks—would readily have understood it as compatible with solvent inkjet printing using light-transmitting inks. …The JPO decision's contrary finding is erroneous.
Translator’s notes (editorial)
The author’s summary says 非透光 (“non-light-transmitting”), whereas the quoted reasoning concerns 透光 (“light-transmitting”). Both source statements are retained.
