Short Summary
The Board instituted IPR2020‑01206 on 294 claims of the ’691 patent and held eight claims unpatentable for anticipation by Grupp ’483, while leaving the remaining claims intact.
Detailed Summary
In IPR2020‑01206, the PTAB instituted a review of 294 claims of U.S. Patent No. 9,905,691 B2, which relates to depinning the Fermi level in metal‑semiconductor junctions using thin interface layers. Petitioner (GLOBALFOUNDRIES) asserted that the prior‑art patent Grupp ’483 anticipates the metal‑oxide features of several claims and challenged the written‑description support for oxide‑of‑titanium dependent claims. The Board concluded that claims 1‑4, 13, 20, 22 and 25 are unpatentable under 35 U.S.C. §102, rejected the belated written‑description arguments, and found the specification does not enable the full range of specific‑contact‑resistivity values, thereby affirming partial unpatentability.
Practitioner Note
This case demonstrates the evidentiary and procedural standards applied in patent matters before local courts. Understanding the court's reasoning in GLOBALFOUNDRIES Inc. et al. vs OAK IP LLC is valuable context for structuring arguments or assessing risk in similar proceedings.
