When a competitor makes, sells, uses or imports a product that falls within the scope of your patent claims without authorisation, and a defence does not apply, that is patent infringement under the Patents Act 1990 (Cth). Patent infringement can occur in other circumstances. Effective enforcement requires lawyers who understand both the technical subject matter and the mechanics of Federal Court litigation.

Our Expertise
Patent Infringement Claims
Acting for patent owners where a competitor is exploiting a patented invention without licence. We assess whether the infringing product or process falls within the scope of the patent’s claims — the technical analysis that determines whether infringement is established — and pursue the most effective enforcement strategy.
Freedom to Operate & Infringement Risk
Advising product developers and businesses on whether their product or process infringes existing patents before commercialisation — reducing the risk of costly infringement proceedings and identifying design-around options where necessary.
Patent Validity & Invalidity
Patents can be challenged on grounds including lack of novelty, obviousness and insufficient disclosure. We assess validity as part of every infringement matter — if the patent being asserted against you has weaknesses, that changes the strategy fundamentally.
Defence of Patent Claims
Acting for respondents facing infringement allegations — assessing the scope of the asserted claims, identifying validity challenges, and pursuing the most commercially effective resolution. Not every patent claim has merit, and early rigorous assessment can determine the outcome.
Urgent Injunctions in Patent Matters
Where ongoing infringement causes immediate commercial harm — particularly where a competing product is in active market distribution — we apply for urgent interlocutory injunctions halting infringement pending resolution of the underlying dispute.
Patent Licensing & Commercial Resolution
Many patent disputes resolve through licensing rather than litigation. EAGLEGATE advises on licensing strategy and negotiates licence terms — using the strength of the patent position and litigation risk as leverage to achieve commercially sound outcomes.

Our Approach to Patent Infringement
Assess the Patent and the Conduct
Clear-eyed assessment of the patent’s scope, its validity and the alleged infringing conduct. That analysis — reading claims with technical and legal precision — determines everything that follows.
Map the Strategy
Patent litigation is resource-intensive. We map a strategy proportionate to the commercial stakes — identifying whether the matter is better resolved through negotiation, licensing, urgent injunction or full proceedings.
Enforce or Defend
Where proceedings are required, we act with precision — preparing technical evidence, engaging expert witnesses, managing discovery and appearing in the Federal Court.
Resolve on Optimal Terms
Patent disputes frequently settle. The terms of settlement depend on the strength of the position we have built. We pursue the outcome that reflects the true value of the IP at stake.
Why EAGLEGATE
- Patent Litigation vs Patent Attorney — Understanding the Difference: Patent attorneys specialise in obtaining patents — drafting specifications, filing applications, and prosecuting claims through IP Australia. Patent litigation is distinct: it involves taking disputes to court, building an infringement case, and running Federal Court proceedings. EAGLEGATE brings the litigation expertise.
- Technical Depth — Our lawyers have backgrounds in engineering, technology and science. That technical grounding enables us to read patent claims intelligently, understand expert evidence, and analyse infringing products and processes with precision.
- Doyle’s Guide-recognised 2020–2026 — Seven consecutive years of recognition as a Recommended IP Lawyer in Queensland, reflecting a sustained record in IP enforcement and litigation across technical and creative fields.
- Federal Court Experience — We act in the Federal Court of Australia in patent infringement proceedings — from urgent injunction applications through to hearings involving expert evidence and claim construction.
Insights
- What is claim construction?
Patent infringement requires interpreting the scope of the patent’s claims — the numbered statements at the end of the specification that define what is protected. Claim construction determines whether the alleged infringing product or process falls within the patent’s scope. It is a technical and legal exercise that frequently determines case outcomes.
- Can I challenge a patent being used against me?
Yes. Patents can be challenged on grounds including: lack of novelty (the invention was publicly known before the priority date), obviousness (the invention was obvious to a skilled person in light of prior art), and insufficient disclosure.
- How long does patent litigation take?
Federal Court patent proceedings can take 18 months to several years to reach final hearing. However, many matters resolve through injunction, licensing or settlement significantly earlier.
- What remedies are available for patent infringement?
Injunctions to stop ongoing infringement, damages to compensate financial loss, account of profits, and delivery up of infringing products. Urgent interlocutory injunctions can be obtained early in proceedings.
