Lantana Ltd. v. UK Comptroller General of Patents, [2013] EWHC 2673 (Pat)
Earlier this month, High Court Judge Colin Birss released a new opinion on the European view of software patentability as seen through the eyes of an English judge. The basic rule coming from the EPC is that "programs for computers . . . as such" are not patentable. EPC Article 52. This particular case arises from the refusal of the UKIPO (not the EPO) to grant a patent to Lantana. However, the UK Patents Act of 1977 implements Article 52 UK roughly follows the law set down by the EPO.
Digging in, the main subject-matter related question that the UK court asks in software related inventions is whether the invention offers an innovative technological contribution beyond the computer program itself. In HTC v Apple [2013] EWCA Civ 451 and Aerotel Ltd v Telco Holdings Ltd, [2006] EWCA Civ 1371, the UK Court of Appeals explained the four-step process for determining whether a particular claimed invention meets this technological contribution requirement. The steps are:
i) construe the claim;
ii) identify the actual contribution offered by the claimed invention;
iii) determine whether the contribution falls solely within the scope of excluded subject matter (i.e., programs for computers); and
iv) determine whether the contribution is actually technical in nature.
In those cases, the courts made clear that the technical contribution could be either a technological mechanism or a technological effect.
A key point in the US debate on patentable subject matter is whether the technological (or non-abstract) contribution needs to be innovative. In the UK/EPO, the answer is yes, that contribution must itself be innovative in the way that it makes a "contribution to the known art."
Here, Judge Birss followed anything but an integrative approach to patentable subject matter. Rather, the focus is on whether the elements of the invention that qualify as subject-matter-eligible (i.e., technological) also offer an innovative contribution. Lantana argued that this approach conflated the question of subject matter eligibility with those of novelty and non-obviousness. However, Judge Birss disagreed:
Mr Beresford [Counsel for Lantana] submitted that [Judge Birss's approach] conflicted with the acceptance by the examiner that the claim was novel and non-obvious. I do not agree. Those matters [decided by the examiner] apply to the claim as a whole, that is to say the entire combination of features. The point here is a different one, i.e. that the idea of an email message containing machine readable instructions as a contribution to the art in this case is wrong. The computers in the claim are not operating in a new way. . . .
The claim has been found to be novel and inventive by the examiner and in that sense it makes a contribution of some kind to the art [when examined as a whole], but the applicant has been unable to identify anything which this claim can fairly be said to contribute which has a technical character.
Thus, the focus here is on finding elements of the invention that are both innovative and have a technical character. Although Judge Birss did not cite to the U.S. case of Parker v. Flook, 437 U.S. 584 (1978), he could have so reach out for support. In Flook, the U.S. Supreme Court similarly pushed patent applicants for an inventive concept that itself is a practical application, writing:
Even though a phenomenon of nature or mathematical formula may be well known, an inventive application of the principle may be patented. Conversely, the discovery of such a phenomenon cannot support a patent unless there is some other inventive concept in its application.
I suspect that the rule supported by Judge Birss here is not too far removed from that which the current U.S. Supreme Court would also fashion if given the chance. However, the current USPTO does not require that particular elemental linkage.
One important result of this approach – well recognized by Judge Birss is that the scope of subject matter eligibility shifts over time. The Lantana case involves a particular use of email systems. If the patent had been filed in the early days of email and was able to introduce an a technological mechanism that was new at the time then the application would be subject matter eligible. However, the reality is that email systems were already very well known by the time Lantana filed its application. In Judge Birss' words, the technological aspect of the invention was "conventional." As such, there was no technological contribution to be found.
In the end, the result here is that Lantana's appeal has been dismissed with the UKIPO's judgment of nonpatentability still standing.

As an aside, Lantana is a small US based company and the listed inventor John Wysham is the company CEO. The US version of the application (Serial No. 12/867825) was abandoned after a final obviousness rejection.
