Comet ML Inc. has a defensive patent litigation posture, having appeared as a defendant in one tracked case. This single case, Unified Patents v. Comet Ml Inc, was heard before the Patent Trial and Appeal Board (PTAB). Unified Patents is known as a membership organization that challenges patents asserted by Non-Practicing Entities (NPEs) to protect its members from alleged frivolous patent litigation.

The case against Comet ML Inc. at the PTAB indicates that the company is an operating company that has been targeted by a patent challenge. There are no tracked cases where Comet ML Inc. has acted as a plaintiff. The PTAB is a venue where the validity of patents can be challenged, often by companies seeking to invalidate patents that are being asserted against them or their members.
