The Sydney Sectors We Work In

Every Baxter IP attorney holds a technical or scientific degree, so the person drafting your specification understands the technology rather than translating it second-hand. These are the areas our Sydney office sees most.

Medical devices and biotech

The Westmead and Randwick health precincts, and the research base around UNSW and the University of Sydney, make NSW a dense medtech cluster. We draft and prosecute patents for devices, diagnostics and therapeutics, and manage the divisional and PCT strategies that long clinical timelines require.

Fintech, software and AI

Sydney is Australia’s financial centre and most of its fintech is built here. Software is patentable in Australia when it solves a technical problem rather than merely automating a business method — a distinction that decides the outcome of most applications, and one we have drafted through the post-Aristocrat landscape.

Defence and advanced engineering

Defence work carries its own constraints — classified subject matter, foreign filing considerations and export controls all shape when and where you can file. We advise on sequencing protection so a commercial position is not lost to a procurement timetable.

Consumer brands and retail

Most Australian consumer brands are built out of Sydney. We run pre-launch clearance searches, file across the right classes of goods and services, and enforce against copycats before a similar mark becomes entrenched.

University spin-outs and research commercialisation

UNSW, the University of Sydney, UTS and Macquarie generate a steady flow of commercialisable research. We work with founders and technology transfer teams on freedom-to-operate, filing strategy and the IP position investors will scrutinise in due diligence.

Agritech, mining technology and climate

From processing equipment and sensing to resources technology and emissions reduction, we protect the engineering and chemistry behind businesses selling into Australia’s primary industries and into export markets.

What Working With Us Looks Like

You deal with a qualified attorney directly, not an account manager relaying questions. Fees are quoted and agreed before any work begins, so the cost of each step is known in advance rather than arriving afterwards.

Patent attorney services

A technical specialist on your matter

Every Baxter IP attorney holds a technical degree — engineering, chemistry, biotechnology, physics or computer science. Your matter goes to someone who has worked in your field, which is what makes a specification broad enough to be worth having.

Patent attorney services

Fixed and capped fees

We quote a fixed or capped fee for each stage before work starts, so you can budget the whole path rather than the next invoice.

Patent attorney services

Meet in the CBD, or not at all

Our Kent Street office is a short walk from Wynyard and Town Hall. Equally, most matters run entirely by video and email — whichever suits how you work.

Patent attorney services

Protection beyond Australia

We coordinate international filing through the PCT and Madrid Protocol and a global associate network, so an Australian first filing becomes a considered international position rather than a scramble at the 12-month deadline.

Patent attorney services

Ex-Examiner insight

Attorneys who have worked inside IP Australia know how an application will be read before it is filed, which shortens prosecution and reduces the objections you pay to answer.

The Sydney Office

Patent attorney services

Level 21, 207 Kent Street

Our principal office sits in the Sydney CBD between Wynyard and Barangaroo, a few minutes’ walk from Wynyard Station. Call +61 2 9264 6716 or email sydney@baxterip.com.au. Meetings are by appointment so the right attorney for your technology is there when you arrive.

Acting across New South Wales

We act for businesses across greater Sydney and regional NSW — Newcastle and the Hunter, Wollongong and the Illawarra, and the Central Coast, where we also keep an office at Toukley. Because IP rights are granted federally, being outside the CBD changes nothing about the protection available to you. We also act for Victorian clients from our <a href="/services/ip-attorneys-melbourne">Melbourne office</a>, and the two work as one team.

Patent attorney services

Recognised nationally

Baxter IP has been named in IAM Patent 1000 in 2023, 2024 and 2025, recognised by IP Stars as a Notable Firm, and awarded IP Attorney Firm of the Year (Australia) in 2024. Our attorneys are members of the Institute of Patent and Trade Mark Attorneys of Australia.

IP Attorneys in Sydney — Your Questions Answered

Whether you searched for a patent attorney, an IP lawyer or a trademark lawyer in Sydney, these are the questions we are asked most often by NSW clients.

A registered patent attorney is qualified to draft and prosecute patent applications before IP Australia, and must hold a technical or scientific degree as well as passing the patent attorney qualifying examinations — that combination is what the role requires. An IP lawyer, or solicitor, advises on the surrounding legal questions: contracts, assignments, and infringement proceedings in the Federal Court. Baxter IP’s team are registered patent and trade mark attorneys, not solicitors. We secure and defend your rights before IP Australia end to end, and where a matter genuinely requires court litigation we brief and coordinate specialist counsel. So if you searched for an "IP lawyer in Sydney", the work you have in mind is almost certainly attorney work.
Yes. We are at Level 21, 207 Kent Street in the Sydney CBD, between Wynyard and Barangaroo and a short walk from Wynyard Station. Meetings are by appointment so that the attorney who works in your technical field is the one who sees you. Most matters then run by video, phone and email — but the first conversation about an invention is often easier face to face. Full details and a map are on our Sydney office contact page.
The same as anywhere in Australia — cost is driven by the complexity of the invention and the countries you want to cover, not by the city. A provisional application is the usual first step and the least expensive way to secure a priority date while you develop the idea or test the market. A standard Australian application, a PCT international application, or both, follow within twelve months. We quote a fixed fee for each stage before starting, and our guide to what drives patent costs sets out where the money actually goes.
Yes. An Australian trade mark registration covers every state and territory, so one filing protects your brand nationally. The process runs from a clearance search, through selecting the right classes of goods and services, filing with IP Australia, answering any examination report, and then acceptance and a two-month opposition period — typically seven to nine months for a straightforward application. Our step-by-step guide to trade mark registration in Australia covers each stage, or our trade mark attorneys can run it for you end to end.
Possibly not, but treat it as urgent. Australian law provides a twelve-month grace period that can excuse your own prior disclosure, and a provisional application filed now can still secure a priority date. But the grace period does not exist in every country, so a public disclosure can quietly destroy your rights overseas even where Australia forgives it. If you have demonstrated, pitched, sold or published anything, speak to an attorney before you do anything further.
Regularly. We act for manufacturers, technology businesses and agribusinesses in Newcastle and the Hunter, Wollongong and the Illawarra, and across regional New South Wales, and we keep a Central Coast office at Toukley. Because IP rights are federal and almost all of the work is documentary, distance makes no practical difference — matters run by video, phone and email, and you are welcome in the CBD whenever meeting in person would help.
If you have made something that works differently from what exists, that is a patent conversation and it should happen before any public disclosure. If you have a name, logo or product brand you intend to build on, that is a trade mark conversation and it should happen before launch, while changing course is still cheap. If the value is in how a product looks, a registered design may be the right protection. Most first conversations sort out which of the three you actually need, and often the answer is more than one.
