Quick read

  • A patent is only as strong as the specification behind it.
  • A Federal Court patent decision about parking enforcement technology, infringement, prior use, insufficient disclosure and best-method requirements.

Use this to check

  • Patent infringement and patent validity are separate questions, and a patentee can lose on both.
  • Earlier opposition findings do not always stop a later party from raising invalidity grounds.
  • Priority claims need earlier documents that actually disclose the invention clearly enough.

Decision snapshot

  1. 1

    What happened

    • Orikan Group Pty Ltd sued Vehicle Monitoring Systems Pty Limited over a standard patent for vehicle detection technology used in parking enforcement.
    • The dispute had a long background involving earlier vehicle-monitoring litigation, earlier VMS patents, SARB and Orikan technology, patent opposition proceedings and the assignment of the patent to Orikan after a corporate restructure.
    • Orikan alleged that VMS's PODS sensors and parking overstay detection systems infringed claims of the patent.
    • VMS denied infringement and cross-claimed that the patent was invalid.
  2. 2

    What the court had to decide

    • The Federal Court had to determine whether VMS's PODS parking overstay detection sensors and methods infringed Orikan's vehicle detection patent, whether VMS had a prior-use defence, whether earlier patent opposition findings created any estoppel, and whether claims 1 to 24 of the patent were invalid for insufficient disclosure, lack of entitlement to...
  3. 3

    What the court decided

    • The Court concluded that Orikan failed to establish infringement of the relevant patent claims by VMS's PODS sensors and methods.
    • It also held that claims 1 to 24 were not entitled to a priority date before 7 August 2013, that VMS had a prior-use defence, that VMS had established invalidity for insufficient disclosure and failure to disclose the best method, and that Orikan had made unjustifiable threats of infringement proceedings.

Practical impact

Practical read

  • A patent is only as strong as the specification behind it.
  • Product businesses should make sure the patent teaches the real implementation, records the best known method and does not rely on earlier priority documents that cannot support the claimed invention.

Useful next steps

  • Patent infringement and patent validity are separate questions, and a patentee can lose on both.
  • Earlier opposition findings do not always stop a later party from raising invalidity grounds.
  • Priority claims need earlier documents that actually disclose the invention clearly enough.
  • Best-method disclosure matters where the applicant knew a better practical implementation at filing.
  • Threatening infringement proceedings can become risky if the claims are later not infringed or invalid.

Practical read

This is a dense patent judgment, but the business story is familiar: two technology businesses were fighting over who controlled a commercially useful product space. The product area was parking enforcement technology. The legal contest was about whether Orikan's patent claims captured VMS's PODS systems, and whether the patent was valid in the first place.

The Court found against Orikan on several fronts. It did not find infringement of the relevant claims by VMS's PODS sensors and methods. It also found that claims 1 to 24 were not entitled to a priority date before 7 August 2013. Because VMS had been exploiting the relevant sensors and methods before that date, VMS also had a prior-use defence.

On top of that, VMS succeeded on invalidity: the complete specification did not disclose the invention clearly and completely enough, and it did not disclose the best method known to the patent applicant at the relevant filing date.

For product and hardware businesses, the lesson is sharp. Patent filings need to explain the invention well enough for the skilled person to perform it without undue burden. They also need to disclose the best method known at filing. If your internal engineering documents contain the real implementation detail and the patent specification stays vague, the gap can become fatal.

The case also shows that winning or surviving earlier opposition steps does not necessarily prevent later infringement and validity arguments from being run in court.

Checks to run

Key points

  • Before asserting a patent, test infringement and validity separately with technical evidence.
  • Compare the patent specification with internal engineering documents before filing or enforcement.
  • Check whether earlier priority documents really disclose the invention now being claimed.
  • Document the best practical method known at filing, especially for software, hardware and sensor systems.
  • Be careful with infringement threats where validity or prior-use issues are live.

Key takeaways

  • Patent infringement and patent validity are separate questions, and a patentee can lose on both.
  • Earlier opposition findings do not always stop a later party from raising invalidity grounds.
  • Priority claims need earlier documents that actually disclose the invention clearly enough.
  • Best-method disclosure matters where the applicant knew a better practical implementation at filing.
  • Threatening infringement proceedings can become risky if the claims are later not infringed or invalid.
