Verdict

Operating-company assertion

The only assignment recorded is from the inventors to Balanced Body Inc. [cite: 031388/0606], the original assignee and a known manufacturer of Pilates equipment that ships products embodying the claims. There are no signals of the patent being transferred to a shell entity or a known NPE.
