                          COMMISSIONER'S DECISION

 

    STATUTORY - Section 2: Pathological Test Process

 

    Method for determination of antigens in an aqueous fluid of a living

    animal (including humans), not possible by conventional methods, is

    not a treatment applying medicine to such a living animal; and satisfies

    the criteria of a "useful" process or art within the definition of Section

    2(d) in that it belongs to the manual or productive arts, it is controllable,

    and it has utility in practical affairs; and a patent therefore is not

    contrary to the public interest.

 

    FINAL ACTION: Overruled.

 

                                  ******************************

    This decision deals with a request for review by the Commissioner of

    Patents of the Examiner's Final Action dated May 10, 1972 on

    application 003,389, This application was filed in the name of

    Antonius H.W.M, Schuurs and refers to "Immunochemical Determinations

    Of Antigens And Antibadies".

 

    In the prosecution terminated by the Final Action the examiner rejected

    claims 1 to 8 as covering non patentable subject matter under Section

    2(d) of the Patent Act.

 

    Claim 1 reads:

 

    Method for the immunochemical determination, by means of an

    agglutination reaction, of antigens or antibodies in an aqueous

    solution in which they are present in a concentration too low to

    be reliably determined by conventional agglutination reaction

    procedure without prior fractionation or concentration or are

    attended with factors disturbing to conventional agglutination

    reactions arising from contaminants present in the aqueous

    solution to be tested, comprising

 

(a) adsorbing one of the immunochemical reaction components

    selected from the group, consisting of antigens and

    antibodies on carrier particles suitable for antigens

    and antibodies;

 

(b) reacting said component by joining it with the aqueous

    solution to be tested containing the other reaction

    component to be deterniined;

 

(c) separating the carrier particles, after the reaction

    has taken place, from the reaction mixture:

 

(d) resuspending the particles in a small volume of a suitable

    aqueous medium; and

 

(e) visually determining the reaction pattern of the carrier

    particles.

 

In the Final Action the examiner stated in part:

 

Applicant's arguments imply that the meaning "Any new and useful

art, process, ...." must be given the broadest possibly interpre-

tation and any subject matter encompassed by this definition is

patentable, unless the Patent Act specitically forbids it, This

is not the case, however, as the Patent Office has consistently,

over many years held the view that everything that is new and use-

ful is not necessarily patentable and it is well established that

there are arts and processes which are definitely excluded from

patent protection, some by statute (as in Section 28(3) of the

Patent Act) and others by court decisions; for example, methods

dependent on professional skill (See Lawson vs. Commissioner of

Patents or Tennessee Eastman Co, vs. Commissioner of Patents). In

the area of processes the Patent Act is designed to protect those

which have novelty, utility, inventive ingenuity and are also

susceptible of industrial application

 

Although the present method for the immunochemical determination

of antigens or antibodies may be new, useful and unobvious, it is

however not susceptible of industrial application. The method

here, which is performed on a non-industrial product, viz., human

body fluids, is rather conceived as being essentially non-economic

as it does not produce a result in any way associated with trade,

commerce or industry in the sense that those expressions have been

used in the above particular patent case judgements and is also

contrary to the spirit of the expression "working on a commercial

scale" referred to in the Patent Act. Therefore, it is deemed

not being in the public interest to grant patents for such methods

of pathological diagnosis.

 

In the response of November 10, 1972 the applicant stated in part:

 

Now applicants will admit that the provisions of Section 2(d)

require some qualification which, as the Examiner has correctly

put, arise either from the provisions of Section 28(3) of the

Patent Act or from court decisions. However, in applicants' view,

neither Section 28(3) nor the pertinent decisions of the courts

require Section 2(d) to be qualified in such a manner that a

patentable process must be "susceptible of industrial application".

Rather, applicants would urge that the relevant criteria are more

accurately identified by Dickson C.J. lit National Research

Development Corporation's application (Australia) (1961) RPC

135 where, at page 145, the following statement is made in the

judgement:

 

"The point is that a process, to fall within the limits of

patentability which the context of the Statute of Monopolies

has supplied, must be one that offers some advantage which is

material, in the sense that the process belongs to a useful

art as distinct from a fine art (see Virginia-Carolina

Chemical Corporation's Application (1958) R.P.C. 35 at p.

36) that its value to the country is in the field of

economic endeavour. (The exclusion of methods of surgery

and other processes for treating the human body may well

lie outside the concept of invention because the whole

subject is conceived as essentially non-economic:, see

Maeder v. Busch (1938), 59 C. L. R. 684 at p. 706.)"

 

This passage was referred to in the judgment of Cattanach J. in

the decision of the Exchequer Court in Lawson v. Commissioner of

Patents. In summary, it appears to be necessary that a patentable

process belongs to a useful art as distinct from a fine art and

is not essentially non-economic. These criteria appear to have

been accepted by the Office in recent decisions of the Patent

Appeal Board.

 

In applicants' submission, the subject matter of claims 1 to 8

does belong to a useful art as distinct from a fine art or, in

the words of the Patent Appeal Board in the decision referred to

above, does relate to a manual or productive art as distinct

from a fine art. The method steps of the claims comprise those

which are set out clearly in claim 1 as steps (a) to (c) inclusive.

It is submitted that these steps clearly do not belong to a "fine

art" involving the use of professional skills having judgmental

content, and are not for instance comparable to methods of

surgery and other processes of treating the human body. Moreover,

such methods appear most frequently today to be carried out by

commercial testing laboratories (clinical laboratories) who bill

the customer directly for their services even though in some cases

such matters may be covered by medical insurance, Thus, even if

the method is not susceptible of industrial application, it

certainly is of commercial application and yields a result that

is essentially of an economic nature in that such a test

procedure is ordered and paid for in the ordinary way of business.

Furthernnore it is beside the point that the method is performed

on a non-industrial product; it is submitted that the relevant

criterion is whether the method is susceptible of commercial

application.

 

At the outset the Board observes that the Final Action at the time

 

conformed with Patent Office guidelines relating to the patentability of

 

inventions involving methods of testing of human body fluids, as distinct

 

from such other testing processes as those applied to other natural

 

products, or to industrial products, or to materials used in the manufac-

 

ture of such products, even though the end result of the test process is not

 

necessarily a physical product in that it may be tangible information only.

 

The basic issue is whether the subject matter of the process claims 1 to 8

constitutes a "useful art or process" within the meaning of Section 2(d)

of the Patent Act defining patentable subject matter, and more particularly

whether the subject matter satisfies the principles and criteria applied by

jurisprudence dealing with the question. In cases of claims involving

methods of testing the established criteria of utility is usually the

critical area in determining whether such subject matter is a patentable

invention within the meaning of Section 2(d) of the Patent Act. In the

present case the prerequisites of novelty and unobviousness are assumed

since no objection has been made on such grounds.

 

Section 2(d) of the Patent Act reeds:

 

"invention" means any new and useful art, process,

machine, manufacture or composition of matter, or any

new and useful improvement in any art, process, machine,

manufacture or composition of matter.

 

Recently there has been two Exchequer Court caves of particular interest

 

in the interpretation of Section 2(d) of the Patent Act. They are

 

J. Wyburn Lawson v The Commissioner of Patents (1970) 62 C.P.R. 101,

 

which concerns claims to a plot of land subdivided in a certain manner,

 

and Tennessee Eastman v The Commissioner of Patents (1970) 62 C.P.R. 117,

 

which concerns claims directed to a method of surgical bonding of body

 

tissues of human beings.

 

The question of whether a subject matter is an "art" or a "process"

 

was considered In Re Lawson v Commissioner. In that case "art", "process" and

 

"method" were viewed as one and the same thing, and in any event it was

 

settled that "art" may include a method or process citing Refrigerating

 

Equipment Limited v Waltham Systems Incorporated (1930) Ex. C.R. 154 at

 

166, wherein Cattanach J. then stated at page 109:

 

"An art" or operation is an act or series of acts performed

by some physical agent upon some physical object and producing

in such object some change either of character or of condition.

It is abstract in that it is capable of contemplation of the

mind. It is concrete in that it consists in the application of

physical agents to physical objects and is ithen apparent to the

senses in connection with some tangible object or instrument.

 

And at page 110 he also stated:

 

It is now accepted that if the invention is the means and

not the end, the inventor is entitled to a patent on the means.

 

That the process under consideration falls within that meaning of an

"art" is a matter of fact in that the process consists in the appli-

cation of physical chemical agents to a physical solution, the result-

of which is then apparent in the treated solution, for if there is no

physical or chemical change in the character or condition of the solution

as a result of applying the process, it would not be possible to determine

the reaction pattern of the carrier particles in the solution after, as

well as before, the physical or chemical agents performed upon it. On the

other hand, In Re Lawson v Commissioner, supra, it was held that as a

result of the process then under consideration, neither the character

nor the conditian of a material object ytas in any way physically changed,

nor was the user's ability to deal with it in anyway increased or decreased.

 

The other factor to be decided is whether the "art" in terms of the present

process satisfies the prerequisites of being a "useful" art or process

within the meaning of Section 2(d), which may be conveniently stated,

inter alia as to: whether the subject matter is useful in a "manual or

productive art" (as distinct from a fine art such as that in which novelty

is solely the exercise of professional skills, or that having intellectual

meaning or aesthetic appeal alone), whether the subject matter is con-

troliable and reproducible by the means disclosed so that the desired

result inevitably follows whenever it is worked, and whether the subject

matter has utility in practical affairs (as that in relation to trade,

commerce or industry) which is beneficial to the public.

 

Since the subject matter of the present process is in the "means", as

distinct from the "end", it should be entitled to a patent within the

meaning of a manual or productive art as stated In Re Lawson v Commissioner,

supra. The fact that the relevance of the end result of the present process

eay be applied in connection with the treatment of living animals is

incidental to the subject matter of the present invention, it is a fact

that the present process does not apply any pharmaceutical properties of

a substance to affect or employ the physiological processes of a living

animal. That patentability should be denied merely because treatment

of a living animal is a prerequisite of the usefulness of the end produced

is untenable since it would be wide enough to exclude medicines as well

as their processes of manufacture intended to be governed by Section 41(1),

new and obvious tests for quality assurance of industrially produced

pharmaceuticals, and such other inventions intended to have medical and

surgical application. The foregoing conforms to the S.C.C.'s decision

In Rc Tennessee Castman v Commissioner of Patents, of December 19, 1972

(unreported), (on appeal from the Exchequer Court's decision on the same

case, supra) when it stated that the process then under consideration of

applying a medicine to a human being "...is clearly in the field of practical

application" as opposed to a mere scientific principle or abstract theorem

excluded by Section 28(3) of the Patent Act.

 

In the S.C.C.'s decision Tennessee Eastman v Commissioner, supra, it was

held that patents for medical treatment per se must be excluded under

the Patent Act in that the use of a medical substance cannot be claimed

by a process apart from the process of producing it. In any event the

present claims distinguish factually from the claims then under consid-

eration in that no step of medical or surgical treatment is set out in the

claims. It is also noted that in this decision the Supreme Court seemed

to equate its decision with the latest reported case brought to its

attention, In Re Schering A.G.'s Application (1971) RPC 337 , a case

dealing with a method of contraception, citing the conclusion of the

Patent Appeal Tribunal at page 345 as follows:

 

   Although, however, on a full consideration of the matter it

seems that patents for medical treatment in the strict sense must

be excluded under the present Act, the claims subject of the

application do not appear to fall within this prohibition and, on

the law as it stands today, they should at least at this stage in

our judgement, be allowed to proceed. As swift's Application (1962)

RPC 37 in the Divisional Court of the Queen's Bench Division clearly

established, the Office and the Patents Appeal Tribunal are at this

stage not deciding the question of "actual patentability", as the

phrase was used in that case, and unless there is no reasonable

doubt that a manner of manufacture is not being claimed or the appli-

cation is plainly without justification, it is their duty to allow

the claim. The applicants will then have the opportunity in due

course, if the matter arises, of having "actual patentability"

decided in the High Court. (Emphasis added by the Court)

 

It is also of interest to note that the material advantage and the economic

issues were indicated by the citation of the National Research Development

Corporation's Application (1961) RPC 135 in both the Lawson v Commissioner

and Tennessee v Commissioner (Exchequer Court), supra, wherein it is stated:

 

   The point is that a process, to fall within the limits of

patentability which the context of the Statute of Monopolies

has supplied, must be one that offers some advantage which is

material in the sense that the process belongs to a usefut art

as distinct from a fine art (sec Virginia-Carolina Chemical

Corporations's Application (1958) RPC 35 at p. 36) -- that its

value to the country is in the field of economic endeavour.

(the exclusion of methods of surgery end other processes for

treating the human body may well lie outside the concept of

invention because the whole subject is conccived as essentially

non economic: see Maeder v Busch (1938) 59 C. I..R  684 at p. 706).

(Emphasis added)

 

The Board is therefore satisfied that the present state of the law

provides no basis on which to exclude the present subject matter from

patent protection. The subject matter lies in the field of a "useful art"

as opposed to a "fine art", "abstract theorem" or "scientific principle".

It is an invention which is inherently beneficial to the public, and one

which is reproducible and controllable to produce the desired result when-

ever it is worked or used. Furthermore, it has utility in practical affairs,

has commercial application and is not contrary to the public interest.

 

In the circumstances, therefore, the Board is satisfied that the Commissioner

ought not to refuse claims 1 to 8 on the grounds that the subject matter

falls outside the statutory requirements of Section 2(d) of the Patent

Act, and recommends that the Final Action refusing claims 1 to 8 be

withdrawn.
