Biotechnological Inventions
Technical Expert Group on Patents law Issues - December 2006
Examination Guidelines for Patent Applications relating to Biotechnological Inventions at
the UK Patent Office
These Guidelines set out the practice within the UK Patent Office as it relates to patent
applications for biotechnological inventions. The 2000 Regulations came into force on 28
July 2000 and implemented the provisions of Articles 1 to 11 of the European Directive
98/44/EC on the legal protection of biotechnological inventions.
In the UK, the Patents Regulations 2000 confirmed and clarified that inventions concerning
biological material, including gene sequences, may be legitimately the subject of patent
applications. In other words, these Regulations have established beyond doubt the
legitimacy of biotechnology patents in the UK.
"An invention shall not be considered unpatentable solely on the grounds that it
concerns (a) a product consisting of or containing biological material; or (b) a process
by which biological material is produced, processed or used"
[Paragraph 1, Schedule A2 to the Patents Act 1977]
Universally, it is an established practice that a natural substance which has been
isolated for the first time and which had no previously recognized existence, does not
lack novelty because it has always been present in nature.
It is generally agreed, and it is particularly relevant in the field of biotechnology,
that a patent should not be granted merely because the applicant had been involved in
laborious and costly effort. If the goal is known and sufficient of the theory and
practice is known for the applicant to predict where he is going, without there being an
original step, then an obviousness objection would be well founded.
Following the sequencing of various genomes, there is unlikely to be an inventive step
in identifying from within a sequenced genome any new gene, even those without known
homologues. It is obvious to trawl the genome for previously unidentified genes, and any
skilled worker would have some expectation of success. In Genentech, an idea was
considered obvious if "the materials in question were lying in the road and ready for
a research worker to use", even if the skilled man faced a number of obstacles in
proceeding to his goal. However, if overcoming these obstacles required "a spark of
imagination
.beyond the imagination properly attributable to him as a man skilled in
the art" then there may be some element of inventive step. The use of bioinformatics
tools would not seem to pose obstacles requiring a spark of imagination to overcome.
Paragraph 2 of Schedule A2 to the British Patents Act, 1977 permits biological material
which is isolated from its natural environment or produced by means of a technical process
to be the subject of an invention even if it previously occurred in nature. Claims to
micro-organisms per se have been allowed on the grounds that they are products of
microbiological processes. This applies even when they are merely isolated from their
natural surroundings, their isolation, culture, characterization and the finding of a
utility turning what would be a discovery into an invention.
Claims for micro-organisms per se which have been isolated or obtained by artificially
induced random mutation, are allowed but generalizations from such specific
micro-organisms to novel species would not normally be permitted. On the other hand,
claims to genetically modified micro-organisms derived from readily available known
micro-organisms where the invention resides in the gene introduced, may be claimed more
generally. Also claims to mutants and variants of a specified deposited micro-organism are
allowed provided they possess the same inventive property as the deposited micro-organism.
Patenting of Micro-organisms in China
Claims for micro-organisms per se are allowed in China. DNA sequences are
considered to be large chemical compounds, and may be patented as compositions of matter.
Although patent claims to naturally occurring DNA sequences might be expected to trigger
the products of nature rule, courts have upheld patent claims covering
purified and isolated DNA sequences as new compositions of matter resulting
from human intervention. An excised gene is eligible for a patent as a composition of
matter or as an article of manufacture because that DNA molecule does not occur in that
isolated form in nature; or synthetic DNA preparations are eligible for patents because
their purified state is different from the naturally occurring compound.
Article 25 of the Chinese Patent Law states that:
For any of the following, no patent right shall be granted:
Scientific discoveries;
Rules and methods for mental activities;
Methods for the diagnosis or for the treatment of diseases
Animal and plant varieties;
Substances obtained by means of nuclear transformations.
For processes used in producing products referred to in items (4) of the proceeding
paragraph, patent right may be granted in accordance with the provisions of the Law.
Patenting of Micro-organisms in Europe
The European Union has defined "'biological material" instead of
"micro-organism", as under [Article 2.1 (a)]
"Biological material means any material containing genetic information and capable of
reproducing itself or being reproduced in a biological system"
In Plant Genetic Systems application (T356/93) European Board of Appeal was seized with
the question as to what is meant by the term 'micro-organism' The Board held that a
micro-organism would include bacteria, yeast, fungi, algae, protozoa, plasmids and
viruses, but also animal or plant cells and generally all unicellular entities with
dimensions beneath the limits of human vision.
Article 53(b) of the European Patent Convention (EPC) provides that European patents shall
not be granted in respect of plant or animal varieties or essentially biological
processes for the production of plants or animals; this provision does not apply to
microbiological processes or the products thereof.
In its decision of 16 June 1999 the Administrative Council inserted a new Chapter VI
entitled Biotechnological inventions in Part II of the EPC Implementing
Regulations. The new provisions entered into force on 1 September 1999 and implemented the
requirements of the EU Biotechnology Directive in European patent law. The EPO has
introduced four new rules, Rules 23b to 23e. Rule 23b sets out general matters and defines
the meaning of biotechnological inventions, biological material, plant variety, and
microbiological process. Rule 23c states patentable biotechnological inventions,
including:
Biological material isolated from their environment, even if known in nature. This
particularly applies to genes that are isolated from their natural environment by means of
technical processes and made available for industrial production.
Plants or animals if the invention is not confined to a single variety
The provision clarifies the scope of Article 53(b) of EPC. It indicates that a plant
grouping characterized only by a particular gene, but not by its whole genome, is not
covered by the protection of new varieties and therefore is in principle patentable. This
also applies if such plant grouping comprises plant varieties.
Rule 23d sets out what is not patentable. This includes processes for cloning human
beings, processes for modifying the genetic identity of human beings, using human embryos
for commercial purposes and modifying the genetic identity of animals such as may cause
them suffering without substantial medical benefit. The list is to be seen as giving
concrete form to the concepts of ordre public and morality.
Rule 23e indicates what is and is not patentable with respect to the human body. The human
body and its elements cannot be patented. However, elements of the body, when isolated
from the body, may be patented.
Patenting of Micro-organisms in Japan
In 1997, the Japanese Patent Office (JPO) published its Implementing
Guidelines for Inventions in Specific Fields. Inventions in the biotechnology field
in the Guidelines are divided into four types: genetic engineering, micro-organisms,
plants and animals. Inventions relating to genetic engineering include those of a gene, a
vector, a recombinant vector, a transformant, a fused cell, a recombinant protein, and a
monoclonal antibody. Inventions relating to micro-organisms include micro-organisms per se
as well as those relating to the use of micro-organisms.
In Japan, micro-organism means yeast, molds, mushrooms, bacteria, actinomycetes,
unicellular algae, viruses, protozoa, etc. and further includes undifferentiated animal or
plant cells as well as animal or plant tissue cultures.
Patenting of New Chemical Entity in US:
According to the United States (US) Food and Drug Administration (FDA), a new molecular
entity (NME) or new chemical entity (NCE) means a drug that contains no active moiety*
that has been approved by FDA in any other application submitted under section 505(b) of
the Federal Food, Drug, and Cosmetic Act.
Patenting of Micro-organisms in USA
Art. 35 USC Sec 101 of the US patent law states: whoever invents or discovers any
new and useful process, machine, manufactures, or composition of matter, or any new and
useful improvement thereof, may obtain a patent thereof
"
In USA, utility requirement in respect of biotech inventions are very strict. A discovery
that is not a creation does not meet the requirement of utility. A newly discovered
micro-organism existing in nature, a newly discovered plant per se are discoveries because
they do not involve creativity. Inventions that are incapable of industrial application do
not meet the requirement of utility. Inventions of a gene, a vector, a recombinant vector,
a transformant, a fused cell, a recombinant protein and a monoclonal antibody whose
utility is not described in a specification or cannot be inferred, do not meet the
requirement of utility. An invention of a micro-organism per se, a plant per se or an
animal per se whose utility is not described or cannot be inferred does not meet the
requirement of utility.
According to the new Utility Examination Guidelines of the USPTO, if an
isolated DNA fragment has a specific, substantial, and credible utility, the DNA fragment
invention satisfies the requirement of utility and a patent can be granted for the DNA
fragment. Where a new use is discovered for the patented DNA fragment, that new use may
qualify for its own process patent. Of course, the later patent is a dependent patent of
the DNA fragment patent.
Patenting of Micro-organisms in Australia
The Australian patent law defines invention as "any new manner of
manufacture."
The question of patents for living organisms was considered at length in Ranks Hovis
McDougall Ltd.'s Application [1976 A OJP 3915] and the Court held that:
No objection can be taken to a claim to a new organism on the ground that it is something
living;
Any new variants claimed must have improved or altered useful properties and not merely
have changed morphological characteristics which have no effect on the working of the
organism; and
Naturally occurring micro-organisms per se are not patentable as they represent a
discovery and not an invention, but a claim to a pure culture in the presence of some
specified ingredients would satisfy the requirement of a technical intervention.
The guidelines for a micro-organism in Australian Patent Law states, "what is
discovered in nature without any practical application, is a mere chemical
curiosity"' and is not patentable [Part 8.2.5.3 Australian Manual of Patent
Practice]. However, isolated micro-organisms are considered patentable.
Patenting Practices of Micro-organism in Brazil
Article 10 states that the following shall not be considered inventions or utility models:
"all or part of natural living beings and biological materials found in nature or
isolated there from, including the genome or the germ plasm of any natural living being
and any natural biological process."
Article 18 states that the following should not be patentable:
"living beings, in whole or in part, except for transgenic micro-organisms meeting
the three requirements of patentability - novelty, inventive step and industrial
application - in accordance with Article 8 and which are not mere discoveries."
For the purposes of this law, transgenic micro-organisms mean organisms, except for plants
or animals in whole or in part, that due to direct human intervention in their genetic
composition express a characteristic that cannot normally be achieved by the species under
natural conditions.
