Which patent law firms are most active in Australia? What are typical filing strategies and how do firm differ in terms of client structure? This is what this report is about.
Before getting started, here is a few words about the dataset we analyze: It contains all national AU filings as well as PCT filings handled by Australian patent law firms since 2014. These patents can be granted patents as well as published patent applications.
Upfront, it is important to understand how we allocated the applications to the respective years. We use a mix of patent filing dates and dates of the earliest publication. Whenever an application is itself the priority filing, a direct AU foreign filing or a PCT application filed by an Australian law firm, we refer to the application filing date. However, when an AU application is a subsequent of a foreign priority and filed on the PCT route, we use the earliest publication date. This distinction is necessary because, in the raw data, PCT-based national phase applications usually receive the filing date of the underlying PCT rather than the actual filing date of the national filing. The earliest publication date is much closer to actual time an Australian law firm has worked on the filing.
For priority applications, patents information are published 18 months after they have been filed. Therefore, figures cannot yet be complete for 2017 and 2018 applications/grants. We have included the latest publications we have available.
