Move back to patentability of computer implemented business methods in Australia? Rokt Pte Ltd v Commissioner of Patents [2018] FCA 1988

Since the Federal Court decisions of RPL[1] and Research Affiliates[2] scoping the limitations on patenting computer implemented inventions, the Australian Patent Office has taken a firm position in rejecting patent applications on the basis the claimed invention is mere computer implementation of a business method and not patentable subject matter.

In the recent Federal Court decision, Rokt Pte Ltd v Commissioner of Patents (which is the subject of an appeal), the Court provided guidance for the Commissioner to take a more open minded approach to considering patentability of these types of inventions. 

In this case, the Federal Court allowed an appeal from a patent office re-examination decision to revoke acceptance of a patent application for a "digital dynamic, context-based advertising system".  In so doing the Court provided some clarity in relation to the patentability of computer-implemented business methods which should assist patent applicants and attorneys in considering patentability.

Key takeaways

  • This should effect a change in climate for the Commissioner of Patent's approach to patent protection for computer-implemented business methods - but there is unlikely to be any quick change to the manner in which patents of this nature are examined by the Australian patent office.
  • Judgment on appeal to the Full Federal Court in Encompass Corporation Pty Ltd v InfoTrack Pty Ltd [2018] FCA 421 which raises similar issues to this case is still reserved and this eagerly awaited judgement will be extremely important in assisting understanding as to the patentability of computer-implemented business methods are considered – it is the Full Court's opportunity to revisit RPL and Research Affiliates.


The claimed invention in the Rokt case, the computer implemented "dynamic context based advertising system".  With a priority date of December 2012, the invention claimed a different method to then used computer based advertising.  As distinct from search based advertising (sponsored link advertisements or organic results returned from a user's key word searches) and display based advertising (eg banner advertisements displayed reactive to the content being viewed by the computer user), the method of advertising involves first engaging the with computer user through an "engagement offer" prior to any advertising being shown.  This engagement offer might be the offer of a coupon, competition, survey or provision of a sample.

The engagement offer is designed to capture a user's attention, but not to effect a direct advertising benefit.  It is during the course of the engagement offer that advertisements are selected and displayed responsive to the consumer's interaction with the engagement offer.

The advertisements, designed to directly lead to the sale of a product, are generated for the given user based on previous interactions with the system, and the interactions of similar users. 

The invention uses a widget in the publisher's site to monitor the user's interaction to determine when to display the engagement offer and to monitor the interaction with the advertisements displayed.

The purpose of the invention is the provision of a common platform to relate consumers visiting content on publisher websites to advertising derived from advertisers, making use of wide-ranging data to rank engagement offers.  The data generated is from the target consumer and other consumers interacting with the system and is to generate an engagement score and a revenue score to rank.

Before the Patent Office, the application had been rejected on the basis that the substance of the invention was a business innovation – the delegate found that while "the computer and server are doing novel things…these features are merely implemented by the “custom software”.

Since the Full Court's decision in Grant v Commissioner of Patents[3], it is settled law that a business method per se is not patentable subject matter.  Prior to RPL and Research Affiliates, computerised business methods were generally accepted as patentable subject matter, because the use of the computer created a technical effect and therefore met the manner of manufacture test from NRDC[4].  However these two Full Federal Court cases changed that practice in the Patent Office, so that patent application examination since 2014 has required the Patent Examiners to consider carefully whether the invention is simply putting a business method into a computer "to implement the business method using the computer for its well-known and understood functions"[5], and not patentable subject matter.

So the critical question to be determined in the Rokt case was whether the invention could be characterised as an improvement in computer technology, or whether it was just putting a business method into a computer.

On appeal

On appeal, Robertson J said that while there was a business problem – attracting the attention of the use and having the user choose to interact with the advertiser – that this was translated into a technical problem – how to utilise computer technology to address the business problem. 

Taken in isolation, Robertson J found that certain aspects of the invention were known - a database, a client-server architecture, the running of the Javascript program on a publisher's website and the creation of a raking engine to rank abstract data to achieve an ordered list were each known as at the priority…
