Australia’s leading applicants for standard patent applications in 2025 span multinational corporations, globally active technology firms, specialised manufacturing companies and domestic innovators (Figure 2.5). The diversity of applicants underscores the breadth of engagement with the patent system across sectors of the Australian economy.

Lead domestic and international filers for standard complete patents in Australia in 2025International leaders
The largest international patent filers in Australia in 2025 include firms such as LG Electronics, Huawei, Caterpillar, Regeneron Pharmaceuticals and Nestlé. These organisations operate at global scale and maintain substantial R&D intensity, with patenting closely integrated into product development, technology deployment and market entry strategies.
Caterpillar, the world’s largest manufacturer of construction and mining equipment, appears as a prominent filer in 2025, consistent with rising activity in transport, heavy machinery and electrified industrial systems.
Regeneron Pharmaceuticals retains its position among leading filers, reflecting sustained biologics development and strategic portfolio protection in life sciences.
The composition of the international top filers remains broadly stable year-on-year, indicating continued engagement by globally integrated firms with the Australian patent system.
Australian leaders
Among Australian applicants, Aristocrat Technologies remains the leading domestic filer, with 123 standard patent applications in 2025. Its sustained position reflects an intensive patent strategy in gaming systems and digital platforms.
Beyond Aristocrat, the next tier of domestic filers recorded volumes in the range of approximately 40 to 55 applications. A notable feature of the 2025 rankings is the reduced prominence of public research organisations and universities among the top domestic filers compared with earlier years. Similarly, Canva – which had featured prominently in recent editions of this report – recorded a substantial reduction in Australian filings and does not appear among the top domestic applicants in 2025.
These shifts occurred alongside an overall increase in resident filings nationally. The pattern suggests that growth in Australian patenting in 2025 was less concentrated among large institutions and globally-oriented technology firms, and more distributed across a wider set of domestic applicants.
At the same time, the recent growth in resident filings has been driven primarily by repeat filers rather than a surge in new entrants to the patent system.
Interpreting the rankings
The rankings are based on the number of standard patent applications filed (including original and divisional applications). Applicants differ in their approaches to divisional filings (dividing an application into more applications), portfolio management, and progression to grant. As such, filing volume should not be interpreted as a direct measure of innovation output or commercial success.
Applicant residency is based on the origin that an applicant provides in their first application to IP Australia.
