Case No. 2025 (Ne) 10049
[Portable information communication device]
(Presiding Judge Hasegawa)
= Cases No. 2025 (Ne) 10051, 2025 (Ne) 10047, 2025 (Ne) 10040, Tokyo District Court No. 2022 (Wa) 70131, etc.
A patent that had previously prevailed in patent infringement litigation against Sharp and SoftBank was held invalid on the basis of a different primary reference.
The primary reference was found to be the same as the patent at issue in a particular use situation.
⇒ If this is the logic, would not the same have been true of the primary reference in the Sharp and SoftBank cases?
(*A new defense based on correction was raised in the appeal, but the corrected invention was held readily conceivable.)
(Excerpts from the judgment — translated)
A mobile phone is normally premised on use while carried by a user, and it goes without saying that, in that situation, even if the resolution of the image data to be displayed is greater than the screen resolution of the built-in display panel, the image data is transmitted to and displayed on the built-in display panel.
Thus, when implementing the function of displaying image information that cannot be clearly displayed on the simplified liquid crystal display panel 23, the mobile phone of the invention in Exhibit Otsu 6 is found to transmit that image information to the simplified liquid crystal display panel 23 and display it.
