JUDGMENT
ALDOUS
LJ
This
appeal raises, not I expect for the last time in this Court, the question of
whether a patent application falls within the ambit of Section 1(2) of the
Patents Act l97l and is therefore excluded from being a patentable invention.
On
6 March l992, the appellants, Fujitsu Ltd applied in this country for a patent
claiming priority from a Japanese application. The application was published
under No. 2254458A, but was objected to by the Examiner upon the ground that it
related to a method for performing a mental act and to a programme for a
computer and therefore was excluded by Section 1(2)C of the Act. That view was
upheld, after an oral hearing, by Mr Haselden, a Principal Examiner acting for
the Comptroller. The appellants appealed. Their appeal was rejected by Laddie
J. Against his judgment and Order the appellants appeal.
The
statutory provisions
Section
l of the Patents Act l977 defines what are patentable inventions and also lists
some things that are not patentable. The relevant parts of that section read:
(1) A
patent may be granted only for an invention in respect of which the following
conditions are satisfied, that is to say -
(a) the
invention is new;
(b) it
involves an inventive step;
(c) it
is capable of industrial application;
(d) the
grant of a patent for it is not excluded by subsections (2) and (3) below;
and
references in this Act to a patentable invention shall be construed accordingly.
(2) It
is hereby declared that the following (among other things) are not inventions
for the purposes of this Act, that is to say, anything which consists of -
(a) a
discovery, scientific theory or mathematical method;
(b) a
literary, dramatic, musical or artistic work or any other aesthetic creation
whatsoever;
(c) a
scheme, rule or method for performing a mental act, playing a game or doing
business, or a programme for a computer;
(d) the
presentation of information;
but
the foregoing provisions shall prevent anything from being treated as an
invention for the purposes of this Act only to the extent that the patent or
application for patent relates to that thing as such.
....
Those
provisions have to be construed in the light of the European Convention and
with the help of the judgments given by the European Patent Office. As
Nicholls LJ said in
Gales
Application
(1991) RPC 305 at 322.
"One
of the purposes of the l977 Act was to give effect to the European Patent
Convention. Thus, section 77(1) provides that a European patent (UK), by which
is meant a European patent designating the United Kingdom, shall as from a
prescribed date be treated for the purposes of parts 1 and 3 of the Act as if
it were a patent under the Act granted in pursuance of an application made
under the Act. Section 77(4) provides that where a European patent (UK) is
revoked in accordance with the European Patent Convention, the patent shall be
treated for the purposes of parts 1 and 3 of the Act as having been revoked
under the Act.
The
Act had a further purpose. The Act did not merely enact the statutory
provisions necessary for the provisions of the Convention regarding European
patents to take effect in this country. The Act also had a harmonisation
objective. On the signature of the Convention for the European Patent for the
Common Market, referred to in the Act as the Community Patent Convention, and
not to be confused with the European Patent Convention, the governments of the
member states of the European Community resolved to adjust their laws relating
to patents so as to bring those laws into conformity with the corresponding
provisions in the European Patent Convention and other conventions.
Accordingly, when construing and applying section l(l) and (2) of the Act, the
court must have regard to the legislative intention with which those
subsections were framed, namely, that they were framed so as to have, as nearly
as practicable, the same effect in the United Kingdom as the corresponding
provisions in Article 52(1), (2) and (3) of the European Patent Convention have
in the territories in which that Convention applies. That is the effect of
section 130(7) in the present case.
From
this brief reference to the European Patent Convention one point which emerges
is that it is of the utmost importance that the interpretation given to section
l of the Act by the courts in the United Kingdom, and the interpretation given
to Article 52 of the European Patent Convention by the European Patent office,
should be the same. The intention of Parliament was that there should be
uniformity in this regard. What is more, any substantial divergence would be
disastrous. It would be absurd if, on an issue of patentability, a patent
application should suffer a different fate according to whether it was made in
the United Kingdom under the Act or was made in Munich for a European patent
(UK) under the Convention. Likewise in respect of opposition proceedings."
The
patent application
The
application is entitled "Method and Apparatus for Creating Synthetic Crystal
Structure Images." At the heart of the invention is a method for modelling a
crystal structure for use in designing inorganic materials in the fields of
chemistry and physics. The basic idea utilises a computer programmed so that
the operator can select an atom, a lattice vector and a crystal face in each of
two crystal structures displayed on the display unit. Upon instruction the
computer, using the selected requirements, converts data representing the
physical layouts of the two crystal structures into data representing the
physical layout of the crystal structure that would be obtained by combining
the original two structures in such a way that the two selected structures are
superposed. The resulting data is then displayed to give a picture of the
combined structure.
I
understand that the crystal structures which the inventor particularly had in
mind are those of semiconductors and superconductors. Thus a scientist wishing
to investigate what would result if he made a new material consisting of a
combination of two existing compounds would enter data representing each of
those compounds into the computer. The structure of the two compounds would
then be displayed. The operator then selects how they should be joined by
selecting the relevant atom, the lattice vector (atomic bond) and a plane. The
computer then generates and displays the new structure using the data supplied.
The
specification opens with a general statement as to what the invention relates.
It then explains how in the manufacture of new inorganic materials, such as
superconductors materials and semiconductors, it is known to produce models to
study in advance their physical attributes. The specification states:
"Conventionally,
the modelling of a crystal structure of an inorganic material is carried out by
operations of assembling a plastic model of structure elements and tracing the
assembled structure. In this conventional modelling of the crystal structure,
as an operator actually assembles the plastic models of the structure elements
by hand, the assembly is hard for the operator."
The
specification then sets out the consistory clauses which show that the
invention is claimed both as a method and as a computer apparatus. The
relevant claims are:
"1. A
method of processing first and second images representing first and second
crystal structures to produce a third image representing the structure of a
synthetic crystal structure, the first and second images being stored as
respective first and second sets of data items, the first set of data items
representing, in a first coordinate system, the plurality of atoms and lattices
in the first crystal structure, and the second set of data items representing,
in a second coordinate system, the plurality of atoms and lattices in the
second crystal structure, which method comprises the steps of:
using
the computing means for selecting a pair of crystal faces, one from each of the
first and second crystal structures, having respective mutually-similar
arrangements of atoms, and, for each crystal face of the selected pair,
selecting an atom and a linear array of atoms in the face;
using
the computing means to transform the second set of data items to produce a
third set of date items representing, in the said first coordinate system, the
respective atoms of the second crystal structure arranged so that the selected
atom of the second crystal structure can be superposed on the selected atom of
the first crystal structure and so that atoms of the selected linear array of
the second crystal structure can be superposed respectively on those of the
selected linear array of the first crystal structure, and so that the selected
crystal faces then coincide in a common plane, the remaining atoms of the
second crystal structure being located to one side of that plane whilst the
remaining atoms of the first crystal structure are located to the opposite side
of that plane;
using
the computing means to combine the first and third sets of data items together
to produce the third image as a representation of a crystalline combination of
the said
first
and second crystal structures; and
using
display means of the computing means to display the resulting third image in a
form by which the physical properties of the crystalline combination can be
studied.
9. A
method of manufacturing a structure which is a crystalline combination of two
crystal structures, the method comprising an investigation of the effects of
combining the two crystal structures using a method according to any one of the
preceding claims.
10. A
computer apparatus for creating a computer image of a synthetic crystal
structure formed of a first crystal structure having a plurality of atoms and
lattices and a second crystal structure having a plurality of atoms and
lattices, said apparatus comprising:
computer
storage means for ....
selection
means for selecting from ....
specifying
means, coupled to said selecting means, for
specifying
....
transformation
means for transforming said ....
computer
display means for displaying ...."
The
Principal Examiner held that the invention amounted to no more than a programme
for a computer and also was no more than a method of performing a mental act.
It was therefore excluded by Section l(2)(c) of the Act.
The
Judge concluded that the claims in form were not to a computer program as such,
but that:
"In
this case, Fujitsu's application leaves it to the operator to select what data
to work on, how to work on it, how to assess the results and which, if any,
results to use. The process is abstract and the result of use of it is
undefined. What is produced is not an inevitable result of taking a number of
defined steps but is determined by the personal skill and assessment of the
operator. As such it consists in substance of a scheme or method for
performing a mental act and is unpatentable."
The
law
Section
1(2)(c) of the Act has been considered by this Court in
Merrill
Lynch's Application
(1989) RPC 561 and in
Gales'
Application
.
In both those cases the Court drew attention to the proviso to Section 1(2)
which states that the "things", referred to in the subsection, should only be
excluded "to the extent that a patent or an application for a patent relates to
that thing as such."
In
Merrill
Lynch
the applicants submitted that the question for the Court was to decide whether
the subject matter of the claim was a computer program. If it was, it was not
patentable. If it was not, then the invention was not excluded from
patentability by Section l(2). Thus it was said that a piece of machinery (a
computer) which follows the instructions of a computer program was patentable,
although the program itself would be excluded from patentability by the
Section. That was rejected by the Court of Appeal. Fox LJ said at page 569:
"It
seems to me to be clear, .... that it cannot be permissible to patent an item
excluded by section l(2) under the guise of an article which contains that item
- that is to say, in the case of a computer program, the patenting of a
conventional computer containing that program. Something further is necessary.
The nature of that addition is, I think, to be found in the
Vicom
case where it is stated: 'Decisive is what technical contribution the
invention makes to the known art.' There must, I think, be some technical
advance on the prior art in the form of a new result (eg a substantial increase
in processing speed as in
Vicom)."
By
that statement Fox LJ was making it clear that it was not sufficient to look at
the words of the claimed monopoly. The decision as to what was patentable
depended upon substance not form. He also went on to point out the importance
of considering whether the invention made a technical contribution, despite the
fact that neither the statute nor Article 52 of the Convention lays down that
the matter, which would result in the invention not relating to the thing as
such, must provide a technical contribution. It would therefore seem that as a
matter of words, if for instance the patent was not confined to a computer
program, then it could not be excluded under subsection (2), as to an extent
the patent would not relate to the computer program as such. However it is and
always has been a principle of patent law that mere discoveries or ideas are
not patentable, but those discoveries and ideas which have a technical aspect
or make a technical contribution are. Thus the concept that what is needed to
make an excluded thing patentable is a technical contribution is not
surprising. That was the basis for the decision of the Board in
Vicom.
It has been accepted by this Court and by the EPO and has been applied since
l987. It is a concept at the heart of patent law.
The
reasons for the decision of the Technical Board in
Vicom
T208/84, 1987 2 EPOR 74 have to be read against the background of the invention
claimed. It was for a method of digitally processing images and an apparatus
for carrying out the method. The invention as claimed involved scanning the
elements of a data array to produce a convolved array and then repeating the
scanning so that the last convolved data array generated had the enhanced
qualities required. That claim was objected to as being a method of performing
a mental act as such and as a computer program as such contrary to Articles
52(2) and (3) of the Convention.
The
Board allowed the appeal. They drew a distinction between a method of
performing a mental act which was not patentable and a technical process. They
pointed out that use of a mathematical process did not produce a technical
result. They went on:
"In
contrast thereto, if a mathematical method is used in a technical process, that
process is carried out on a physical entity (which may be a material object but
equally an image stored as an electric signal) by some technical means
implementing the method and provides as its result a certain change in that
entity. The technical means might include a computer comprising suitable
hardware or an appropriate programmed general purpose computer.
The
Board, therefore, is of the opinion that even if the idea underlying an
invention may be considered to reside in a mathematical method a claim directed
to a technical process in which the method is used does not seek protection for
the mathematical method
as
such
."
The
Board then came to consider the objection that the invention was excluded as it
related to a computer program as such. They rejected that objection,
essentially upon the same reasoning. They said:
"Generally
claims which can be considered as being directed to a computer set up to
operate in accordance with a specified program (whether by means of hardware or
software) for controlling or carrying out a technical process cannot be
regarded as relating to a computer program
as
such
and thus are not objectionable under Article 52(2)(c) and (3) EPC.
....
Generally
speaking, an invention which would be patentable in accordance with
conventional patentability criteria should not be excluded from protection by
the mere fact that for its implementation modern technical means in the form of
a computer program are used. Decisive is what technical contribution the
invention as defined in the claim when considered as a whole makes to the known
art."
Mr
Birss submitted that the decision in
Vicom
showed that patent applications for processing images of real things were not
excluded from being patentable. He took us to the claim which had been
considered by the Examining Division which limited the invention to a method of
filtering a two-dimensional data array and compared that with the claim that
was allowed which claimed a method of processing images. He submitted that it
was the change from filtering to processing real images that supplied the
technical contribution.
The
reasoning in
Vicom
as to what was the technical contribution is not easy to ascertain. However I
do not read the Decision as concluding that all claims to processing real
images are patentable and I can see no reason why, if they are, the same
reasoning should not apply to all useful images. As I read the Decision, the
Board saw a technical contribution, namely the generation of the enhanced
picture. As the principal Examiner pointed out:
"The
numbers which are mathematically processed in
Vicom
do not merely determine the intellectual content of the images which are
displayed, but are also the technical means which cause the display to operate
to a technical level. Thus in
Vicom
manipulating numbers in the manner described affects the technical quality of
the image. So in
Vicom,
the invention concerned the technical representation, or technical control of
what is displayed and not the information content of what is displayed."
In
my view
Vicom
does not support the submission that claims to processing of real images are
allowable. The technical contribution was not the fact that an image was being
produced. It was the way the enhanced image was produced.
In
Gale
this Court had to consider a patent application for a ROM programmed to carry
out a method of calculating a square root of a number. Nicholls LJ who gave
the leading judgment described the working of a computer and said:
"In
principle, the instructions in a computer program do no more than prescribe a
particular manner of operation for which it was constructed. Thus writing a
fresh set of instructions for use in a computer in particular circumstances or
for particular purposes cannot in itself be regarded as inventive."
He
went on to point out that, to be used in a computer, a series of instructions
had to be recorded in some physical form perhaps on a disc in a ROM. He said
that if the instructions qua instructions were not patentable, they were not
patentable merely because they were recorded on or in a known piece of
apparatus. The disc on ROM was "merely the vehicle used for carrying" the
instruction.
"...
the physical differences are not material for patent purposes, because they
constitute no more than the use of a compact disc for its intended purpose.
Likewise with a disc or ROM which records or reproduces a new set of
instructions, if those instructions are recorded on a conventional disc, or are
stored in a ROM using conventional methods. To decide otherwise would be to
exalt form over substance."
He
went on to conclude that the application before him did not contain a technical
contribution and therefore was a computer program which was excluded from
patentability.
I,
like Nicholls LJ, have difficulty in identifying clearly the boundary line
between what is and what is not a technical contribution. In
Vicom
it seems that the Board concluded that the enhancement of the images produced
amounted to a technical contribution. No such contribution existed in
Gale's
Application which related to a ROM programmed to enable a computer to carry out
a mathematical calculation or in
Merrill
Lynch
which had claims to a data processing system for making a trading market in
securities. Each case has to be decided upon its own facts.
Does
the application consist of a program for a computer as such?
The
Principal Examiner considered in depth the submissions put forward on behalf of
the Appellants on this topic and concluded that the invention did consist of a
computer program as such. He held that it did not provide any technical
contribution of the type required. He said:
"In
essence, this brings me back to the question I posed above which is whether the
fact that what is displayed is a technical artefact, viz a crystal structure,
is sufficient to confer technical character on the full invention on the facts
in this case. In this respect however, the opening page of the specification
points out that it is known to model inorganic chemicals used in plastic models
of structural elements assembled by hand by an operator and it is I think
against that background that the substance of the present invention is seen in
its proper context. In the absence of any disclosure to the contrary, the
display must be taken to be wholly conventional at the technical level so the
present invention amounts to no more than the provision of a technically
conventional computer programmed to combine the contents of two displays of
crystal structures in a particular way to produce a third composite crystal
structure. In fact of course, all that the display is arranged to do is to
substitute elements of one structure in another, thus mimicking what has
previously been done manually with plastic models. Thus, what is disclosed is
in substance a conventional computer system programmed to display pictures of
crystal structures. While crystal structures undoubtedly do lie in a technical
field ... the pictures displayed are simply substitutions derived by taking
part of one picture and superposing it on another picture and it seems to me
that this process is not of a technical nature but is no more than a purely
intellectual process of substitution. ... I do not dispute that a designer
could use the pictures displayed in the process of designing a new compound
..., but it still seems to me that the substance of the invention disclosed is
simply a conventional computer programmed to display the same images as were
previously produced using plastic models and in my view this does not involve a
technical advance of the kind which I am required to find."
The
Judge held:
"I
have already referred to the essence of Fujitsu's development. It is clear
that, in form at least, claims are not to programs as such. It follows that,
prima facie, they avoid the 'program' exclusion under Section 1(2). However as
Fox LJ said in
Merrill
Lynch
something further is needed. The real issue it seems to me, is whether the
application also avoids the other exclusions under Section l(2). If it does
not, the application will fail. Whether, in those circumstances, the grounds
of failure are stated to be that the invention is only for a program or that it
is, for example, a method for performing a mental act is a matter of semantics."
He
went on to hold that the application was excluded as it consisted in substance
of a scheme or method for performing a mental act.
I
am not sure whether the Judge came to any conclusion as to whether the
application consisted of a computer program as such. Clearly he considered
that in form the claims were not excluded from being patented, but seemed to
believe that there was no difference in this case between the two grounds of
exclusion.
Mr
Birss sought to rely upon the form of the claims. He submitted that claim l0,
directed as it was to a computer apparatus having a number of features and
claim 9 directed to a method of manufacturing a structure could not be said to
relate to an invention consisting of a computer program as such.
That
submission cannot be right having regard to the judgment of Nicholls LJ in
Gale.
In
that case, I held at first instance that the ROM claimed was not excluded as it
was an article which had been altered during manufacture so as to perform the
function of the method or program defined by the claim. The Court of Appeal
decided that that was not correct and that the Court should look at the claims
as a matter of substance. It was both convenient and right to strip away, as a
confusing irrelevance, the fact that the claim was for "hardware".
There
is only one invention. The fact that it is claimed as a method, a way of
manufacture or an apparatus having appropriate features is irrelevant. Further
there is no dispute as to what the invention is. In summary it uses a computer
program so that an operator can select an atom, a lattice vector and a crystal
face in each of two crystal structures displayed. The computer, upon
instruction and using the program, then converts data representing the physical
layouts of the two crystal structures into data representing the physical
layout of the structure that is obtained by combining the original two
structures in such a way that the selected atoms, the selected lattice vectors
and the selected faces are superposed. The resulting data are then displayed
to give a picture of the resulting combined structure. Clearly the whole
operation revolves around the computer program and the question for decision is
whether there is a technical contribution so that it cannot be said that the
invention consists of a computer program as such.
Mr
Birss put forward two grounds for concluding that the application included a
technical contribution. First, relying on
Vicom,
he submitted that the technical contribution was provided by the processing of
real images or structures. I have already concluded that
Vicom
does not support so rigid a view. Thus this submission must be rejected.
Second, he submitted, that the application provided a new tool for modelling
crystal structure combinations which relieved the chemist of the laborious task
of building a model. It provided a solution to the problem of providing a
quick and error free way of creating real images of two crystal structures
joined together.
Mr
Birss is right that a computer set up according to the teaching in the patent
application provides a new "tool" for modelling crystal structure combinations
which avoids labour and error. But those are just the sort of advantages that
are obtained by the use of a computer program. Thus the fact that the patent
application provides a new tool does not solve the question of whether the
application consists of a program for a computer as such or whether it is a
program for a computer with a technical contribution.
I
believe that the application is for a computer program as such. I agree in
general with the reasons of the Principal Examiner which I have quoted. In
Vicom
the technical contribution was provided by the generation of the enhanced
display. In the present case the combined structure is the result of the
directions given by the operator and use of the program. The computer is
conventional as is the display unit. The two displays of crystal structures
are produced by the operator. The operator then provides the appropriate way
of superposition and the program does the rest. The resulting display is the
combined structure shown pictorially in a form that would in the past have been
produced as a model. The only
advance
is the computer program which enables the combined structure to be portrayed
quicker.
I
conclude that the application does not relate to a patentable invention as it
is excluded by Section 1(2)(C) as being a program for a computer as such.
Does
the claim consist of a method of performing a mental act as such?
The
fact that a patent application consists of a program for a computer does not
mean that it does not also consist of a method of performing a mental act. The
contrary is not true. In this case the computer program is the result of
intellectual input, but whether the claimed invention, which incorporates
operator control, consists of a method of performing a mental act as such is
doubtful. As there is no need to decide this issue, I conclude that an
in-depth analysis is best left to be dealt with on another occasion. However,
in the light of the submissions of Counsel I will set out my views on the point
of construction that was argued.
Mr
Birss submitted that the words "a method for performing a mental act" in
Section 1(2)(c) should be construed as only covering methods which the human
mind carries out. They should not be construed to include the sort of acts
which a human mind could do. If so, the Fujitsu application was not excluded
as it related to a specific way of modelling crystal structures not carried out
by the human mind.
Mr
Silverleaf QC who appeared for the Comptroller submitted that the narrow
construction sought to be placed upon the words "for performing a mental act"
was wrong, contrary to authority and involved reading into the Act words such
as : "as done by the mind".
In
support of the narrow construction Mr Birss referred to the Board's decision in
Vicom.
He suggested that the invention in that case could have been performed by the
human mind, but was held to be patentable because the human mind did not
actually work in the way claimed. The distinction drawn by Mr Birss may be
correct in fact, but the reasoning is not. The reason why the Board concluded
that the invention was patentable was because they concluded there was a
technical contribution. The Board did not analyse how the human mind works and
therefore that did not play a part in their considerations.
Mr
Birss also relied on
Pettersson
T1002/92
(1996) EPOR 1. The invention in that case related to a system for handling
customers queuing for a number of service points. The Technical Board held at
page 8:
"The
wording of Claim l leaves no doubt that protection is sought for a 'system
which is capable to determine the queue sequence of customers', and thus for a
three-dimensional object with the aforementioned capacities. Claim l
explicitly indicates that this system comprises: 'a turn-number allocation
unit, a selection unit, terminals, an information unit and computing means.'
Hence, the wording employed in the claim defines a technical item with at least
five construction components, which item clearly belongs to the category of an
apparatus."
The
Board concluded that in such a case there was a mix of technical and
non-technical elements which meant that the claim was not excluded from
patentability. Again there was no analysis of how the human mind works. The
invention was held to be patentable because there was a technical contribution
with the result that it did not relate to a method of performing a mental act
as such.
There
are good reasons to reject the narrow construction. First, a decision as to
whether an invention is patentable as consisting of a method of performing a
mental act as such should be capable of determination without recourse to
evidence as to how the human mind actually works. If it were to the contrary,
the section would pose an extremely difficult problem. Second, the narrow
interpretation appears to introduce a consideration of novelty which is covered
in Section 1(1)(a). Third, the words used as "a mental act" suggest any mental
act whether done before or not.
A
similar but not identical submission was made in
Wang
Laboratories Inc's Application
(1991) RPC 463 as appears from this extract of my judgment:
"Before
turning to the claims, I must deal with a submission of Mr Burkill, who
appeared for the applicant. He submitted that the words "a scheme, rule or
method for performing a mental act" in section 1(2)(c) only excluded schemes,
rules or methods which were intended to be performed and were capable of being
performed in the human mind. He submitted that the word "for" introduced a
subjective element. Thus, as claim l had as its basis steps which were not
intended to be carried out by a human, in that the human mind would not go
through those steps, the basis of the claim was not excluded matter.
The
word "for" does not, in my view, introduce a subjective element. It means "for
the purposes of". The fact that the scheme, rule or method is part of a
computer program and is therefore converted into steps which are suitable for
use by a person operating the computer does not matter. What is excluded from
being patented is a scheme, rule or method for performing a mental act,
whatever mental steps or process is involved. As I pointed out in
Gale's
Application
,
it is a question of fact to be decided in each case whether the claimed
invention is more than a claim to an invention for a disqualified matter. Just
as a claim to a disc containing a program can be in fact a claim to an
invention for a computer program, so can a claim to steps leading to an answer
be a claim to an invention for a performing a mental act. The method remains a
method for performing a mental act, whether a computer is used or not. Thus a
method of solving a problem, such as advising a person whether he has acted
tortiously, can be set out on paper, or incorporated into a computer program.
The purpose is the same, to enable advice to be given, which appears to me to
be a mental act. Further, the result will be the advice which comes from
performance of a mental act. The method may well be different when a computer
is used, but to my mind it still remains a method for performing a mental act,
whether or not the computer program adopts steps that would not ordinarily be
used by the human mind."
Mr
Birss submitted that the reasoning in my judgment in
Wang
was flawed. He submitted that it was not possible to perform a mental act
using a computer and a claim to a method of using a computer could not be a
claim to a method of performing a mental act. As a matter of semantics that
may be right, but as has been made clear in
Merrill
Lynch
and
Gale,
it is necessary to look at the substance of the application when dealing with
the question of whether it is patentable. A claim to a computer operating in a
particular way is no more patentable than a claim to a computer program. A
claim to a method of carrying out a calculation (a method of performing a
mental act) is no more patentable when claimed as being done by a computer than
when done on a piece of paper. Methods of performing mental acts, which means
methods of the type performed mentally, are unpatentable, unless some concept
of technical contribution is present.
The
task of arriving at the conclusion I have reached, namely that this appeal
should be dismissed, has been made easier by the clear and pertinent
submissions of Counsel.

I
agree. The creation of diagrammatic images of physical objects on the visual
display units of computers which can be turned, revolved and altered at the
bidding of the computer operator is not new. In my opinion, what the
appellants have done here is no more than to produce, brilliant though it may
be, a new computer programme. The invention may be new but as it is no more
than a computer programme it is not patentable.
LEGGATT
LJ
I
too agree that for the reasons given by Aldous LJ this appeal should be
dismissed.
ORDER: Appeal
dismissed with costs; order for a section 20 extension, as handed in; leave to
appeal to the House of Lords refused.
