Under United Kingdom patent law, a patent may only be granted for "an invention". While the meaning of invention is not defined, certain things are not regarded as inventions. Such things are excluded from patentability. This article lists judgments delivered by the UK courts that deal with excluded subject matter.
The provisions about what are not to be regarded as inventions are not easy. There has been and continues to be much debate about them and about decisions on them given by national courts and the Boards of Appeal of the European Patent Office. [1] This article also list some of the discussions that have been had about the different judgments.
Article 52 of the European Patent Convention, which represents the source of UK law in this area and which should have the same meaning [1] states that:

Lawyers, patent attorneys and economists have often debated the effects of the judgments listed above. A list of some papers and articles is provided below. Many of these papers discuss more than one judgment, but they have been ordered according to their primary focus, if there is one.
The patentability of software, computer programs and computer-implemented inventions under the European Patent Convention (EPC) is the extent to which subject matter in these fields is patentable under the Convention on the Grant of European Patents of October 5, 1973. The subject also includes the question of whether European patents granted by the European Patent Office (EPO) in these fields are regarded as valid by national courts.
The WTO's Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), particularly Article 27, is occasionally referenced in the political debate on the international legal framework for the patentability of software, and on whether software and computer-implemented inventions should be considered as a field of technology.
The inventive step and non-obviousness reflect a general patentability requirement present in most patent laws, according to which an invention should be sufficiently inventive—i.e., non-obvious—in order to be patented. In other words, "[the] nonobviousness principle asks whether the invention is an adequate distance beyond or above the state of the art".
Patentable, statutory or patent-eligible subject matter is subject matter which is susceptible of patent protection. The laws or patent practices of many countries provide that certain subject-matter is excluded from patentability, even if the invention is novel and non-obvious. Together with criteria such as novelty, inventive step or nonobviousness, utility, and industrial applicability, which differ from country to country, the question of whether a particular subject matter is patentable is one of the substantive requirements for patentability.
Menashe Business Mercantile Ltd. & Anor v William Hill Organization Ltd. [2002] EWCA Civ 1702 was a patent case regarding Internet usage. The case addressed a European patent covering the United Kingdom for an invention referred to as "Interactive, computerized gaming system with remote control". Menashe sued William Hill, claiming that William Hill was infringing the patent by operating an online gaming system. William Hill's defence argued that it did not infringe the patent because the server on which it operated the system was located outside of the UK, in Antigua or Curaçao. Although accepting that their supply of software was in the UK and that this was an essential part of the invention, they further argued that the patent was for the parts of the system, and as one essential part of the system was not located in the UK, there could be no infringement.
There are four overriding requirements for a patent to be granted under United Kingdom patent law. Firstly, there must have been an invention. That invention must be novel, inventive and susceptible of industrial application.
