Short Summary
The Director denied institution of an IPR against MOSAID's patent, ruling that Infineon failed to adequately explain conflicting claim construction positions taken in district court litigation.
Detailed Summary
In this Institution Decision Review, the Board granted review and subsequently denied institution of the Inter Partes Review (IPR). The Patent Owner argued that Petitioner, Infineon Technologies Americas Corp., had presented inconsistent claim construction arguments between its IPR Petition and related district court filings. The Director concluded that Petitioner did not sufficiently explain these differences or justify a 'wait and see' approach regarding indefiniteness, leading to the vacation of the initial institution decision.
