Proof, not claims

A patent’s status can change with a single filing. Real examples show why the local detail decides the answer.

Dymista: “ceased” is not “expired”

Question: Which Australian patents for Dymista are still active?

What a generalist AI said

The main patent, AU2003244799, was “Expired – Lifetime.” It worked out a 20-year term and missed the term extension entirely.

What Temigis® found

The patent was “ceased” because renewal fees weren’t paid, despite a patent term extension to June 2028. While ceased, the extension was void.

What happened next

The patent was restored after the Patent Office granted an extension of time to pay fees, and expiry is confirmed as June 2028.

Why it matters

“Expired” and “ceased” lead to different decisions, and a status can reverse. The true position depended on a live dispute that had to be tracked.

Dymista: the patents nobody mentioned

What a generalist AI said

“No still-active Australian patents.”

What Temigis found

13 further patents in force, with expiries running to 2038. They include formulation and device patents.

Why it matters

Freedom to operate depends on secondary patents, and generic manufacturers often copy the originator’s device mechanics.

Eliquis (apixaban): a five-month difference

Question: When do patents on apixaban expire in Australia?

What a generalist AI said

A range from about February 2026 to February 2031. It leaned on a US patent family (US 9,326,945) and press reports, so the February date reflects US logic.

What Temigis found

The primary compound patent, AU2002341693, was due to expire in July 2026 after a patent term extension. A formulation patent, AU2011220775, runs to February 2031. An earlier patent, AU2008207537, had ceased.

Why it matters

US and Australian extensions are calculated differently. A launch planned for February would have fallen inside a five-month infringement window.
