Patents?
What is a patent?????
What is a Patent?
• Which rights arise from a granted patent?
Patents I
• A patent application - ”paid-for publication”, source of
information
• A granted patent – a legal document defining an injunction
right & a right to claim damages
• A patent does not give the patentee any right to exploit the
invention
Patents II
• Agreement between inventor and society
– Inventor gets a time-limited monopoly
– Society gets a description of the invention
• Patenting forces publication
– Stimulates exchange of information
– Stimulates research and development
• Alternative to patents
– Secrecy
Patentability Requirements
Patentability Requirements
•

Novelty
Inventive step
Clarity
Conciseness
Enablement
Sufficiency of disclosure
Utility
Industrial applicability
Exceptions to patentability
Novelty
Novelty
• Novelty = not available to the public on the date of filing
• Available = made available to the public without any
confidentiality barriers
• A compound (including proteins and genes) is not known
merely because it is found in nature
• Compounds can be made available by
– decribing the structure of the compound (structural formula or
sequence)
– describing a method of producing/synthesising
– describing a method of isolating/purifying the compound
The Concept of Novelty
State of the Art (known)
1. a cup
Patent Application
1. a cup with a handle (novel)
2. a cup
2. a 15 cm tall cup (novel)
3. a cup
3. a cup adapted to hold coffee
(non-novel)
4. a cup
4. a red cup (novel)
5. a cup
5. a container for liquid (not novel)
The Concept of Novelty
State of the art
1. cells secrete a protein with
activity X
2. the protein with acivity X can be
purified from organism Y using
method Z
3. protein with sequence ...
4. peptide with sequence:
ypskpdnpgedapaedmaryysalrhyin
litrqry (NPY)
5. conservative substitutions can
be made in NPY
Patent application
1. an isolated protein with
sequence ... having activity X
2. an isolated protein with
sequence ... having activity X
3. glycosylated protein with
sequence ...
4. peptide with sequence:
ypskpdnpgeeapaedmaryysalrhyin
litrqry
5. peptide with sequence:
ypskpdnpgeeapaedmaryysalrhyin
litrqry
The Concept of Novelty
State of the art
1. gene X was cloned using primers
A and B
2. genes 1 to N can be used for
treating diseases 1 to N
3. gene x promotes cell division
Patent application
1. gene X having sequence
...........
2. gene 5 for treatment of
obesity......
3. use of gene x as a growth factor
Inventive Step
Non-obviousness
Inventive Step/Non-obviousness
• Inventive step/”non-obviousness”
– Difference between prior art and invention must be of a certain
”size”
– No patents for trivial inventions
– Patents promote technical progress, not stand-still
– Non-obvious for the person skilled in the art
– Person skilled in the art
–
–
–
–
Fictitious person
Not a Nobel prize winner
Average skills
Knows everything (all languages) but is conservative, does not go against
established prejudice, does not try to enter unpredictable areaas nor take
uncalculable risks
Inventive Step/Non-obviousness
• Complex arguments
• Room for creativeness
• Large differences between major patent autorities: EP, JP,
US:
• New sequence (new compound, new structure)
– US – any new stucture is non-obvious
– JP – a significant and unexpected effect must be associated with the
new structure, or undue difficulty in obtaining new sequence
– EP – was the sequence difficult to make? any unexpected technical
effects associated with the new sequence? was it obvious to try and
see?
The Concept of Inventive Step
State of the art (known)
1. a cup
Patent application
1. a cup with a handle (inventive?)
2. a cup
2. a 15 cm tall cup (inventive?)
3. a cup
3. a cup adapted to hold coffee
(non-novel)
4. a cup
4. a red cup (inventive?)
5. a cup
5. a container for liquid (not novel)
The Concept of Inventive Step

purified from organism Y using

A and B
2. genes 1 to N can be used for
treating diseases 1 to N
3. gene x promotes cell division

homology to an enzyme with
activity Y
Patent application
1. gene X having sequence
...........
2. gene 5 for treatment of
obesity......
3. use of gene x as a growth factor
4. isolated and purified protein
having sequence X and enzyme

Clarity, Sufficiency, Enablement, Utility
Clarity, Sufficiency, Enablement
• ”Quality requirements”
– No short cuts by trying to keep part of the invention secret
– No short cuts by filing too early – before invention is complete
– Legal certainty (possible for 3rd party to determine scope of claims)
Clarity, Conciseness
• The claims must be clear and concise
• Results in many definitions:
–
–
–
–
–
Sequence homology
Alignment
Hybridisation
High stringency
Receptor binding
Sufficiency, Written Description
• Description must be sufficient
• Sufficiency – when the skilled person can carry out the
invention – don’t try to leave anything out
• Also a question of credibility
• Written description – you must show that you were in
possession of the invention upon filing – do not file before
you completed the invention
Utility
• Industrial applicability/”utility”
– USA – credible, substantial and specific utility (a use for the
invention) – high hurdle, used by the Patent Office to refuse trivial
or premature applications
– EPO – the industrial applicability of a sequence must be given in the
application (Biotekdirektivet) – low hurdle
Patent Claims
Patent Claims
• The claim defines the invention
• The claim must satisfy the patentability requirements
• The description may only be used to interpret the features
of the claims
Rights arising from Patent I
• Productpatent – forbid others to:
– make, use, offer for sale, sell, import
• Claims
– 1. An isolated polypeptide comprising the amino acid sequence of
SEQ ID No. 2, or a biologically active sequence variant having at
least 70% sequence identity to SEQ ID No. 2.
– 2. A pharmaceutical composition comprising protein X.
– 3. An expression vector comprising a sequence coding for protein X.
Rights arising from Patent II
• Method patent – forbid others to
– Use the method
– Method of manufacture also protects the products
• Claims:
– 1. Use of protein X for the preparation of a pharmaceutical
composition.
– 2. Use of protein X for the preparation of a medicament for the
treatment of disease Y.
– 3. A method for identifying a compound with activity X, comprising
testing the compound in screening assay Y.
– 4. A method of producing protein X, comprising culturing a host cell
transfected with vector Y and recovering protein X from the culture
medium.

• First filing– timing
• Early filing –
– Easier to get novelty
– Enablement, sufficiency, utility?
• Later filing –
– More time to prove function (of a gene or protein)

Ethics and Patent Law
Ethics and Patent Law
• Why ethics?
• Controversial issues:
–
–
–
–
–
–
–
Patents on life (Harvard Onco-mouse)
Plant patents
Human genes
Stem cells
Human embryos (cryopreserved embryos)
Breast cancer diagnostics (brca genes)
Computer programs
• ”Non-controversial” issues:
–
–
–
–
Patents on weapons
Patents on nuclear power plants/weapons
Patents on chain-saws
Industrial fishing equipment
For & Against Patents on Genes
• Not novel – but novel in isolated (=available) form
• Not invented by the inventor – but isolated by the inventor
• Isolation is no invention – but the isolated gene can solve a technical
problem and has utility
• Immoral to patent life – why? – living creatures (animals, plants,
microorganisms) have been regarded as goods for centuries
• Patenting genes is contrary to development – mere allegation, do not
confuse patent applications with valid patents
Ethics
• Allegation: claims are way too broad
– Cover all uses (product claims)
– Gene claims should be restricted to use (Biotechnology directive as
implented in France and Germany)
– Stops research
• My answer: gene claims should have same scope as all other claims
– Traditional compound claims cover all uses
– Why should gene patent stop development and research while patents in
other fields enhance research?
– Again: do not confuse patent applications with valid granted claims
• Part of the problem:
–
–
–
–
Backlog of human gene patent applications results in uncertainty
Sequence non-obviousness in the US
USPTO grants invalid patents
Very limited research exemption in the US
