Municipal Parking Services (MPS) contends that its rival continues to ignore the legal standing of the protected technology. Beyond the '172 patent, the patent office recently allowed US Patent No. 12,688,734, dismissing prior art challenges that had been central to the reexamination process. MPS initiated legal action regarding this second patent in July, signaling a broader strategy to protect its intellectual property portfolio.

CEO Joe Caldwell maintains that the patent office has consistently validated claims across multiple pending applications, systematically rejecting the arguments presented by PRRS. While several reexamination proceedings remain open, the recent series of approvals suggests a shift in favor of MPS. The company continues to assert that the ongoing infringement by PRRS warrants the current litigation, as the patent office moves to clear the path for these claims despite persistent opposition.
