Conclusion
In sum, we affirm the district court’s holding that claim 1 of the '352 patent is invalid based on anticipation under 35 U.S.C. § 102(a), as well as its holding that the '352 patent is unenforceable due to inequitable conduct. However, we vacate the court’s ruling that claim 2 of the '352 patent is invalid based on anticipation under 35 U.S.C. § 102(a).
