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 (sometimes called "software patents") are regarded as valid by national courts.
The European Patent Convention (EPC), also known as the Convention on the Grant of European Patents of 5 October 1973, is a multilateral treaty instituting the European Patent Organisation and providing an autonomous legal system according to which European patents are granted. The term European patent is used to refer to patents granted under the European Patent Convention. However, a European patent is not a unitary right, but a group of essentially independent nationally enforceable, nationally revocable patents, subject to central revocation or narrowing as a group pursuant to two types of unified, post-grant procedures: a time-limited opposition procedure, which can be initiated by any person except the patent proprietor, and limitation and revocation procedures, which can be initiated by the patent proprietor only.
The European Patent Convention (EPC), the multilateral treaty instituting the legal system according to which European patents are granted, contains provisions allowing a party to appeal a decision issued by a first instance department of the European Patent Office (EPO). For instance, a decision of an Examining Division refusing to grant a European patent application may be appealed by the applicant. The appeal procedure before the European Patent Office is under the responsibility of its Boards of Appeal, which are institutionally independent within the EPO.
The opposition procedure before the European Patent Office (EPO) is a post-grant, contentious, inter partes, administrative procedure intended to allow any European patent to be centrally opposed. European patents granted by the EPO under the European Patent Convention (EPC) may be opposed by any person from the public. This happens often when some prior art was not found during the grant procedure, but was only known by third parties.
Patentable, statutory or patent-eligible subject matter is subject matter of an invention that is considered appropriate for patent protection in a given jurisdiction. The laws and practices of many countries stipulate that certain types of inventions should be denied patent protection. 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.
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.
G 1/03 and G 2/03 are two decisions of the Enlarged Board of Appeal of the European Patent Office (EPO), which were both issued on April 8, 2004.
T 931/95, commonly known as Pension Benefit Systems Partnership, is a decision of a Technical Board of Appeal of the European Patent Office (EPO), issued on September 8, 2000. At the time, it was a landmark decision for interpreting Article 52(1) and (2) of the European Patent Convention (EPC) but has now largely been superseded by the decisions in T 641/00 and T 258/03.
T 258/03, also known as Auction Method/Hitachi, is a decision of a Technical Board of Appeal of the European Patent Office (EPO), issued on April 21, 2004. It is a landmark decision for interpreting Article 52(1) and (2) of the European Patent Convention (EPC) which built on the principles suggested by the same Board in T 641/00. This decision, amongst others, but notably this one and T 641/00, significantly affected the assessment of an invention’s technical character and inventive step.
Aerotel v Telco and Macrossan's Application is a judgment by the Court of Appeal of England and Wales. The judgment was passed down on 27 October 2006 and relates to two different appeals from decisions of the High Court. The first case involved GB 2171877 granted to Aerotel Ltd and their infringement action against Telco Holdings Ltd and others. The second case concerned GB application 2388937 filed by Neal Macrossan but refused by the UK Patent Office.
T 641/00, also known as Two identities/COMVIK, is a decision of a Technical Board of Appeal of the European Patent Office (EPO), issued on September 26, 2002. It is a landmark decision regarding the patentable subject matter requirement and inventive step under the European Patent Convention (EPC). More generally, it is a significant decision regarding the patentability of business methods and computer-implemented inventions under the EPC.
The grant procedure before the European Patent Office (EPO) is an ex parte, administrative procedure, which includes the filing of a European patent application, the examination of formalities, the establishment of a search report, the publication of the application, its substantive examination, and the grant of a patent, or the refusal of the application, in accordance with the legal provisions of the European Patent Convention (EPC). The grant procedure is carried out by the EPO under the supervision of the Administrative Council of the European Patent Organisation. The patents granted in accordance with the EPC are called European patents.
T 1173/97, also known as Computer program product/IBM or simply Computer program product, is a decision of a Technical Board of Appeal of the European Patent Office (EPO), issued on July 1, 1998. It is a landmark decision for interpreting Article 52(2) and (3) of the European Patent Convention (EPC) and whether computer programs are excluded from patentability under the EPC.
Article 84 of the European Patent Convention (EPC) specifies that the "matter" for which patent protection is sought in an application - the purported invention - shall be stated ("defined") in the claims. This legal provision also requires that the claims must be clear and concise, and supported by the description. The function, form and content of the claims are defined by Article 84 supplemented by Rule 43 EPC.
Article 123 of the European Patent Convention (EPC) relates to the amendments under the EPC, i.e. the amendments to a European patent application or patent, and notably the conditions under which they are allowable. In particular, Article 123(2) EPC prohibits adding subject-matter beyond the content of the application as filed, while Article 123(3) EPC prohibits an extension of the scope of protection by amendment after grant.
Article 83 of the European Patent Convention (EPC) relates to the disclosure of the invention under the European Patent Convention. This legal provision prescribes that a European patent application must disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art.
Under the European Patent Convention (EPC), European patents shall be granted for inventions which inter alia involve an inventive step. The central legal provision explaining what this means, i.e. the central legal provision relating to the inventive step under the EPC, is Article 56 EPC. That is, an invention, having regard to the state of the art, must not be obvious to a person skilled in the art. The Boards of Appeal of the European Patent Office (EPO) have developed an approach, called the "problem-and-solution approach", to assess whether an invention involves an inventive step.
Under case number G 3/08, the Enlarged Board of Appeal of the EPO issued on May 12, 2010 an opinion in response to questions referred to it by the President of the European Patent Office (EPO), Alison Brimelow, on October 22, 2008. The questions subject of the referral related to the patentability of programs for computers under the European Patent Convention (EPC) and were, according to the President of the EPO, of fundamental importance as they related to the definition of "the limits of patentability in the field of computing." In a 55-page long opinion, the Enlarged Board of Appeal considered the referral to be inadmissible because no divergent decisions had been identified in the referral.
Under the European Patent Convention (EPC), European patents shall be granted for inventions which inter alia are new. The central legal provision explaining what this means, i.e. the central legal provision relating to the novelty under the EPC, is Article 54 EPC. Namely, "an invention can be patented only if it is new. An invention is considered to be new if it does not form part of the state of the art. The purpose of Article 54(1) EPC is to prevent the state of the art being patented again."
G 1/83, G 5/83 and G 6/83 are landmark decisions issued on 5 December 1984 by the Enlarged Board of Appeal of the European Patent Office (EPO) on the patentability of second or further medical use of a known substance or composition. They deal with patent claims directed to such second or subsequent medical use, and, as explained in reason 22 of decision G 5/83, the Enlarged Board held that patent claims directed to such substances or compositions were allowable under the European Patent Convention (EPC) when worded as purpose-limited product claims, which are also referred to as "Swiss-type use claims". These decisions are the first decisions issued by the Enlarged Board of Appeal.
