Dispute Summary
Lenovo challenged Ericsson's patent on IMSI encryption technologies before the PTAB, arguing that the claims are obvious in light of prior art. The petitioner relies on combinations of Nair and Forsberg, along with 3GPP standards, to demonstrate lack of non-obviousness. This petition asserts that existing knowledge made the claimed security enhancements predictable.
