IP High Court, 2023 (Gyo-Ke) 10055 — Laser Processing Apparatus (Miyasaka)
“Exhibit Ko 1 has no modified region in the thickness direction of the substrate. Accordingly, there is no need to ascertain the position or size of a modified region in the substrate’s thickness direction, and a person skilled in the art who encounters Exhibit Ko 1 has no … motivation to adopt Feature G relating to Difference 2.”
⇒ Inventive step: affirmed.
* If the “modified region” of the invention at issue is a groundbreaking technical concept absent from the prior art, this is a strong patent. (If a “modified region” had also existed in the prior art, using that prior art as the principal reference might have led to a different conclusion, but this would depend on the other features.)
