Everything about Patentable Subject Matter totally explained
In most
patent laws,
patentable subject matter (or
statutory subject matter) is the requirement that an
invention, for which
patent protection is sought, is of a kind of subject matter that is, by law,
allowed patent protection.
This test is one of the fundamental requirements for
patentability, along with
novelty,
inventive step or nonobviousness, and
utility,
industrial applicability or Manner of Manufacture as defined by the
Statute of Monopolies.
Legislations
The subject-matter which is regarded as being patentable as a matter of policy, and correspondingly the subject-matter which is excluded from patentability as a matter of policy, depends on the national legislation or international treaty.
European Patent Convention
The
European Patent Convention doesn't provide any positive guidance on what
should be considered an invention for the purposes of patent law. However, it provides in a nonexhaustive list of what are not to be regarded as inventions, and therefore
not patentable subject matter:
» The following in particular shan't be regarded as inventions within the meaning of paragraph 1:
» ::
(a) discoveries, scientific theories and mathematical methods;
» ::
(b) aesthetic creations;
» ::
(c) schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers;
» ::
(d) presentations of information.
then qualifies Art. 52(2) EPC by stating:
» The provisions of paragraph 2 shall exclude patentability of the subject-matter or activities referred to in that provision only to the extent to which a European patent application or European patent relates to such subject-matter or activities as such.
(Some further items are excluded under, as formally being not industrially applicable).
Practice at the European Patent Office
Under, "
European patents shall be granted for any inventions which are susceptible of industrial application, which are new and which involve an inventive step." So, four questions need to be assessed:
- Is there an invention?
- Is the invention susceptible of industrial application?
- Is the invention novel?
- Does the invention involve an inventive step?
The first question "Is there an invention?" is equivalent to: "Is the claimed subject-matter as a whole excluded from the realm of patentable subject-matter?" The invention question or patentable subject-matter question necessarily precedes the three further questions, which can't be assessed when there's no invention.
According to the
case law of the
Boards of Appeal of the EPO, the question "Is there an invention?" also implicitly implies the further question: "Does the claimed subject-matter have a technical character?" "
Having technical character is an implicit requirement of the EPC to be met by an invention in order to be an invention within the meaning of ".
Patentable subject-matter considerations also intervene again at a secondary level, during the
inventive step examination.
T 641/00 (Comvik/Two Identities) states that, "
An invention consisting of a mixture of technical and non-technical features and having technical character as a whole is to be assessed with respect to the requirement of inventive step by taking account of all those features which contribute to said technical character whereas features making no such contribution can't support the presence of inventive step." The non-technical features are the ones that are excluded from the realm of patentable subject-matter as a matter of policy.
T 258/03 (Hitachi/Auction Method) further developed this test for patentable subject-matter.
Under this test, a patent application or patent which doesn't provide a technical solution to a technical problem would be refused or revoked as lacking inventive step.
Practice in the United Kingdom
Following the 2006
Court of Appeal judgment in
Aerotel v Telco and Macrossan's application, which contains a lengthy discussion of case law in the area, the UKPO has adopted the following test:
» (1) properly construe the claim
(2) identify the actual contribution
» (3) ask whether it falls solely within the excluded subject matter
(4) check whether the actual or alleged contribution is actually technical in nature.
The Court decided that the new approach provided a structured and more helpful way of applying the statutory test for assessing patentability which was consistent with previous decisions of the Court.
This test is quite different from the test used by the EPO, as expressed in
T 641/00 (Comvik/Two Identities) and
T 258/03 (Hitachi/Auction Method), but it's considered that the end result will be the same in nearly every case. for
patent examiners to determine if a given
claimed invention meets the statutory requirements of being a useful process, manufacture, composition of matter or machine (35 USC 101). These guidelines assert that a process, including a process for doing business, must produce a concrete, useful and tangible result in order to be patentable. It doesn't matter whether the process is within the traditional technological arts or not. A price for a financial product, for example, is considered to be a concrete useful and tangible result (see
State Street decision).
The USPTO has reasserted its position that literary works, compositions of music, compilations of data, legal documents (such as insurance policies), and forms of energy (such as
data packets transmitted over the
Internet), are not considered "manufactures" and hence, by themselves, are not patentable. Nonetheless, the USPTO has requested comments from the public on this position.
The USPTO was prompted to issue the guidelines by a recent decision by their
board of appeals,
Ex Parte Lundgren. This decision asserted that according to US judicial opinions, inventions don't have to be in the "technological arts" in order to satisfy the requirements of 35 USC 101. They must, however, produce a concrete, useful and tangible result.
Computer software as patentable subject matter
The mathematical algorithm exception arose out of three
Supreme Court cases commonly referred to as the “Supreme Court Trilogy.” These cases,
Gottschalk v. Benson,
Parker v. Flook, and
Diamond v. Diehr, represent the only Supreme Court opinions on the patentability of computer software.
The first decision in the trilogy was the
1972 decision of
Gottschalk v. Benson. The invention in this case was a method of programming a general-purpose digital computer using a mathematical algorithm to convert binary-coded decimal numbers into pure binary numbers. The Supreme Court noted that phenomena of nature mental processes, and abstract intellectual concepts were not patentable, since they were the basic tools of scientific and technological work. However, new and useful inventions, which derived from such discoveries, were patentable. The Court found that the discovery in
Benson was unpatentable since the invention was no more than a mathematical algorithm. Despite this holding, the Court emphasized that its decision didn't preclude computer software from being patented, but rather precluded the patentability of software where the only useful characteristic was an algorithm or sequence of algorithms. The Court further noted that validating this type of patent would foreclose all future use of the mathematical algorithm. Therefore, like the traditional exceptions to patentable subject matter, the purpose of the mathematical algorithm exception was to encourage development of new technologies by not granting patents that would preclude others from using abstract mathematical principles.
Controversies
The question of what should and shouldn't be patentable subject matter has spawned a number of battlegrounds in recent years, setting against each other those in each area supporting patentability, claiming that patents would cause increased innovation and public good, against opponents with views that patentability was being sought only for private good but would do public harm.
Flashpoints have included the patenting of naturally occurring biological material; genetic sequences;
stem cells "traditional knowledge";
programs for computers;
business methods.
In the process, different jurisdictions have come to different views as to what should be allowed and what should not.
Patents on business methods have proven to be a particularly controversial type of statutory subject matter. They have been criticized because the patents granted are perceived as being too broad, perhaps due to the difficulty in searching for prior art and recruiting suitably qualified
patent examiners who have historically had a science background rather than a business background. Patent applications for business methods are also subject to delays in prosecution at the
United States Patent and Trademark Office and other patent offices.
