Detailed Summary
The Patent Trial and Appeal Board (PTAB) decided to institute Silicon Motion Inc.'s Inter Partes Review petition against K. Mizra LLC's patent 9111608. The petitioner successfully demonstrated a reasonable likelihood of success in proving that the challenged claims, which relate to memory calibration circuitry for DRAM interfaces, are unpatentable under 35 U.S.C. § 103. The Board found the arguments regarding obviousness over prior art references (Johnson, Moss, Liou, and Stubbs) persuasive enough to move forward with the case.
