The Australian Federal Court has overturned a decision by the Commissioner of Patents and concluded that a computer implemented business method is patent eligible subject matter. In doing so, the Federal Court has clarified in Rokt Pte Ltd v Commissioner of Patents  FCA 1988 that the correct approach when assessing patentable subject matter is to consider the combination of integers as claimed.
Background and Rokt’s Invention
Rokt Pte Ltd (Rokt) applied on 13 March 2013 for grant of an Australian patent entitled “A Digital Advertising System and Method”. Australian Patent Application No. 2013201494 was subject to a re-examination initiated by a Delegate of the Commissioner of Patents (Commissioner) which concluded that the patent application should be refused (Rokt Pte Ltd  APO 34). Rokt appealed the Delegate’s decision.
The main method claim of Rokt’s Australian Patent Application recited a computer implemented method for linking a computer user to an advertising message by way of an intermediate engagement offer. In summary, the method included computer implemented steps of:
- gathering engagement data based on attributes of the user and the content and user interaction with the content;
- communicating engagement data to an engagement engine of a remote advertising system;
- continuously evaluating the engagement data by the engagement engine to determine if a trigger has occurred;
- selecting, by the engagement engine, an engagement offer from a pool if the trigger occurs, the selection based on dynamic ranking of offers in the pool;
- inserting the engagement offer into the publisher content for view by the user;
- determining acceptance of the engagement offer based on consumer interaction;
- presenting an advertising message following the acceptance; and
- gathering user interactions by a script which is communicated to the remote advertising system for use in selecting subsequent advertisements.
Patentability of Rokt’s invention
The Court concluded at  (emphasis added):
“…the substance of the invention was to introduce a dynamic, context-based advertising system, introducing a distinction between an engagement offer, without a direct advertising benefit, and an advertisement designed to lead directly to the sale of the product. This was an improvement in computer technology. It involved the new layer of engagement offers and the insertion of a widget into the publisher content to serve the engagement offer. A data-based scoring algorithm was used to decide what engagement offers to serve. This was an important improvement to existing computer-based advertising. The invention also introduced the recording and transmitting of user interactions with advertisements and the using of that data to select subsequent advertisements.”
The Court highlighted that there was still a requirement that the claimed invention solve a technical problem with a technical solution. However, the Court concluded that Rokt’s claimed invention met this requirement as the specific business problem being addressed was also a technical problem to be solved using a computer. In particular, the Court stated at  (emphasis added):
“I find that there was a business problem of attracting the attention of the user and having the user choose to interact with the advertiser, but this problem was translated into the technical problem of how to utilise computer technology to address the business problem. The invention aimed to solve this technical problem through the introduction of the engagement offer and identifying what steps the software needed to execute in order to modify dynamically the website that the user was browsing while they were browsing it to, first, implement in the web browser or device the concept of the engagement offer, second, to implement in the computer system the necessary software for selecting engagement offers and advertisements for the given user based on the previous interactions with the system and the interactions of other similar users and, third, to have that system interact with the widget in the web browser in real time.”
The Commissioner’s submission, that each integer of Rokt’s invention was well known in isolation, was considered an incorrect approach for assessing patentable subject matter by the Court stating at  and  (emphasis added):
“In addition, known components had been integrated into a single system in an innovative and previously unknown way. The invention brought together some new elements and some known elements to form a working combination that had not previously been achieved and involved the use of computers in a way that was foreign to their normal use as at December 2012.
In light of the Court’s finding that the claimed invention was patentable subject matter, the Commissioner’s decision was set aside and Rokt’s patent application was ordered to proceed to grant. The Commissioner was ordered to pay Rokt’s costs as agreed or taxed.
Reliance on expert evidence
A significant portion of this decision relates to the expert evidence submitted by each party. This is a substantial change in practice as previously the test for patentable subject matter largely turned on the face of the specification. However, as the test for patentable subject matter has evolved to include a comparison of the substance of the invention against the state of the art, practice is also evolving.
This case indicates that Applicants facing patentable subject matter objections from the Australian Patent Office should consider the submission of expert evidence during prosecution of the patent application. For example, the preparation of a statutory declaration outlining the state of the art at the priority date and an explanation of the technical problem and solution of the invention as claimed may be advantageous.
This is a positive decision by the Federal Court indicating that computer implemented business methods, which solve a technical problem with a technical solution, are patentable subject matter in Australia.
We are hopeful that this decision is a precursor to the Full Federal Court decision in the appeal from Encompass Corporation Pty Ltd v InfoTrack Pty Ltd which is expected to issue mid-2019.
