IP High Court, Reiwa 5 (Gyo-Ke) 10110 [Intraoral OCT with color texture] <Judge Honda>
* No inventive step; the JPO appeal decision was upheld.
For element D, “through registration or without registration,” the specification describes both acquiring data along a common optical path without additional processing (without registration) and an alternative using a separate camera with additional processing (through registration).
⇒ If the cited invention satisfies “combining,” the presence or absence of this “through registration or…” limitation does not change the substantive definition of the invention.
As to the technical meaning of “combining,” the claims do not specify the dimensionality of the data.
In light of the specification, it means correlating the R, G, and B values with the IOCT measurement at each coordinate (X, Y). It does not limit the displayed image to a particular dimension or to texture mapping.
⇒ No error in the JPO's findings.
