The THEORY Of INHERENCY 1.
 Nanotechnology is not simply the technology of
the infinitesimally small, but
the technology of the infinitesimally small
accompanyed by at least one novel technical
effect directly resulting from the nanosize.

14
In the Macro
The discovery of a novel property of a known
substance DOES NOT reinstate the novelty of the
same substance.  In fact, the novel property is
considered INHERENT in the known substance.
15
In the Nano
The novel properties characterizing a material in
nanocrystal or nanoparticle form are not
detectable on the same material at macro scale
though purposely looked for.
Therefore It cannot be affirmed that the novel
property exhibited by the material at nanoscale
was inherent in the same material known at
macroscale.
16
Conclusion
the prefix Nano, unlike the prefix
Recombinant in biotechnology, may be able to
reinstate the novelty of a known substance or
material, specifically when accompanied by a
novel technical effect.
If this hypothesis proves valid
17
Inventive Activity
The claimed subject-matter implies an inventive
activity if for the skilled person it is not
obviously derivable from the state of the art
(e.i. Literature).

Some Questions

• Who is the person skilled in the art?
• What is the relevant technical field ?
• Does the downscaling to nanosize endorse the
  invention with an inventive step ?

20
Some Answers
The skilled person a team of persons, each
expert of a different technical field, for
example gene manipulations and semiconductors.
  The relevant technical field. The summ of all
the fields overlapped by the invention.
21
Is Downscaling inventive ?
In the macro NO T 0070/99 (Analytical
devices) The easy miniaturisation of a device or
of an equipment is suggested by the well known
industrial interest of optimizing space and
materials.
22
It is well known that the top-down method has
technical limits. For instance photo lithography
Overtaking these limits by an alternative
top-down method or by novel bottom-up methods,
that means overtaking the limits of available
technology could never a priori be regarded as
obvious.
23
Acquired Novel Property
...when the miniaturisation is accompanied by an
unpredictable effect, the result of
miniaturisation should always be regarded as
inventive
..regardless of the apparent obviousness of the
means used to achieve the result..
24
Decision T 0952/01 (Method of coating a
substrate)
 .. Coating dispersion comprising solid
particles of size 20-70 nm resulting in a special
effect. This effect was lost for particle of
size 70 e 100 nm. Essentially identical coating
dispersions were disclosed in the prior art, but
comprising particles of 100 500 nm.
25
Decision T 0453/97(Antireflective coating for
use in photolithography)
...an antireflective Titanium Nitride (TiN) layer
having thickness between 25 and 40 nm minimized
the percent of reflected radiation to less than
5. In the prior art Ti nitride of 100 nm with
reflected percent of 30
26
T 0453/97
Reflected 5 between 25 e 40 nm
27
Reasonable expectation of success
Therefore the realization of a suggestion is
accompanied by a reasonable expectation of
success. gt No inventive activity.
In traditional technical fields  Procedures
are  known,  standardized,  normally
reproducible.
gt Results predictable
28
In a Pioneer Field 
..An attempt to realize a suggestion is
accompanied by a low expectation of success. gt
Achieving the desired result may prove
inventive...
The procedures are NOT necessarily known,
standardized and repeatable Minor experimental
modifications may strongly affect the expected
results.
Results unpredictable
29
Decision T 0915/00(Nanocrystalline metals)
  The Board affirmed that.. ...the skilled
person had no obvious reason to foresee that the
prior teaching could still be successfully
extrapolated to structures smaller by at least
two orders of magnitudes, if not with the benefit
of hindsight
As many as eight prior documents suggested the
process of the invention for electrodepositing
nanocrystalline Nickel, but in the context of the
microcrystalline structures (gt 1 micron).
30
Clarity (of the claims)
..which is the most suitable claim format for a
nanotech invention.. ..to meet the requirement
of clarity without unreasonably reducing the
scope of protection?
the claims shall define the object of the
protection and shall be clear, concise and based
on the description.

Interpretation of a Product-by-process claim

versus electrodeposition.T 0950/97 specific
surface topography by means of epitaxial growth.
The Board of Appeal of EPO  at nano-scale
level, it is difficult to prove that even minor
modifications in the process parameters are
neutral as regard to the structural features of
the obtained product..
35
Functional Characterization
It is often easier and more reliable to describe
(and to monitor) the novel function caused by the
nano-size than to describe the structural
features of the nano-material causing the novel
function
Antireflective Titanium Nitride (TiN) film
capable of reducing the percent of reflected
radiation to less than 5 (T 0453/97) Chitin
nanocrystallites capable of inhibiting chitinase
activity
36
The Terminology
In a pioneer multidisciplinary area the technical
meaning of the terms is not necessarily
standardized and equally recognized by the
experts of the different overlapping fields.
 Therefore each and every technical term used in
a claim should be properly explained in the
disclosure.
37
Sufficiency of Disclosure
The patent application shall describe the
invention in a manner sufficiently clear and
complete for it to be carried out by the skilled
person.
Sufficiency of Disclosure gt Repeatability of
the invention
38
Interpretation given by Case Law
       Sufficiency of disclosure The skilled
person is able to realize the invention
essentially over the whole claimed ambit. The
realisation of the invention, therefore the
achievement of the declared effects, may not
depend on chance.
39
Generalization of parameters
On Nano-Scale  ..The effect characterizing the
invention depends on the size of the material and
other parameters.. ..the arbitrary
generalization of sizes or parameters gt.. loss
of repeatability of the invention.
On Macro-Scale  ... the claimed subject-matter is
normally a reasonable generalisation of the
real invention,

41
Generalization and not investigated equivalents
On Nano-scale If the application comprises
examples of one sole embodiment of the invention,
gt No protection for equivalent embodiments,
not sufficiently investigated
42
Equivalents
T 0288/02 Prior art Process of epitaxy using as
doping agent atomic o molecular Nitrogen
radicals.. The sole use of molecular Nitrogen
radicals was described with all experimental
details and examples ..
The Board considered that the embodiment
molecular radicals was the only embodiment
actually disclosed, whereas atomic radicals was
merely speculative thus not sufficiently
disclosed
43
Equivalents 2
T 915/00  Generalization
Generalization accepted only because two
subsequent documents substantiated the
repeatability of the process also with metals
other than Nickel otherwise no generalization
accepted
NICKEL In examples
METALS In the claims

44
Metrology Analytical Methods and Tools
 Decision T 1250/01  ... The lack of analytical
means for monitoring one single parameter of the
invention amount to a lack of sufficiency of
disclosure of the invention.
All analytical methods, tests, assays, and
analytical tools necessary to check the
realization of the invention should be described
with all details in the application
