Climb Bio Inc. has filed a lawsuit against Alumis Inc. and Acelyrin Inc. over a $3 million milestone payment dispute related to a January 2024 Asset Purchase Agreement. Climb claims it was invoiced for the payment after dosing its first patient in a Phase 2 trial, despite not receiving any royalty-bearing patents. The company argues its payment obligations are limited to products infringing patents included in the transferred assets, which it asserts it did not receive. Climb is seeking court intervention to clarify its obligations and resolve the dispute.
