Verdict

Operating-company assertion. The absence of any recorded assignments suggests that Swift Paws Inc., the original assignee, retains ownership of the patent. Swift Paws Inc. is an operating company that manufactures and sells lure coursing systems, and they have initiated an infringement suit against a competitor, Zhende Tech, in the Middle District of Florida. This pattern aligns with an operating company asserting its intellectual property.
