                  COMMISSIONER'S DECISION

 

      STATUTORY-LIVING MATTER: Products Comprising Living

                              Microorganisms

 

      Inventions have equal status in satisfying the

    prerequisites of patentability whatever the nature of

    the subject matter. Novelty and unobviousness were not

    grounds of objection. The vaccine composition comprising

    living virus is in no sense a fine art and lies in a

    useful art. The attenuation of the natural activity

    of the virus is produced and controlled by the intervention

    of man, and the vaccine composition inevitably follows the

    conditions disclosed for its production; thus the pre-

    requisites of utility are satisfied and the application

    ought not to be refused by the Commissioner (in re Vanity

    Fair).

 

    FINAL ACTION: Overruled.

 

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

 

      This decision deals with a request for review by the Commissioner

    of Patents of the Examiner's Final Action dated October 28, 1971 on

    application 950,086. This application was filed in the name of

    Behringwerke Aktiengesellschaft (Othmar Ackermann) and refers to

    "Vaccine Against Distemper And Process For Its Preparation".

      In the extended prosecution terminated by the Final Action the

    examiner refused the application because the process of attenuating

    a live virus and the modified living product of such a process, which

    form the subject matter of the claims, do not represent a patentable

    invention according to Section 2(d) of the Patent Act.

         In the Final Action the examiner stated in part:

(a) Section 2(d) of the Patent Act provides a definition of the term

    "invention"; it does not affirm that an invention is necessarily

    patentable. The requirements for patentability are not confined

    merely to novelty and utility. The courts, in interpreting

    Section 2(d), have laid down that, for instance, unobviousness

    is also an essential condition. Moreover, Section 28(3) intro-

    duces a further qualification by stating that no patent shall

    issue for certain types of invention. It follows therefore

    that, taken literally, Section 2(d) does not set forth all the

    requisites for patentability and must be more narrowly construed

    than the wording would suggest.

 

(b) The creation of living things such as new plant varieties, cross

    breeds of animals, viruses, bacteria and the like, and the

    results of such creation do not fall within the scope of subject

    matter to which patentable protection may extend.

 

(c) The case of the Commissioner of Patents vs Ciba Ltd., which the

    applicant has invoked in support of his arguments, relates to

    situations where a known process may acquire patentable merit

    by virtue of the patentability of the product. In the present

    issue the product itself is unpatentable and the case is

    therefore irrelevant.

 

    The applicant in his response of January 28, 1972 stated in

    part:

 

      It is the applicants' belief that the application is not open

    to objection on the grounds stated by the Examiner. Applicants

    agree with the third paragraph of the Official Action wherein the

    Examiner has stated that the definition of the expression "invention"

    must be construed in somewhat narrower terms than those set out in

    Section 2 of the Act. However, where the applicants and the Examiner

    differ is in who has the authority to make this construction. Applic-

    ants believe that construing of the Act is solely the province of the

    courts; the Examiner apparently believes that it is within his authority

    to make such a construction.

 

      It is the applicants' contention that the Examiner has completely

    ignored two relevant pieces of jurisprudence throughout the prose-

    cution of this case.

 

    In American Cyanamid Co. v. Charles E. Frost & Co. (1965) 2 Ex.

    C.R. 355, patents to the antibiotics tetracycline and chlortetracy-

    cline were held to be valid and infringed. The latter was formed

    by placing micro-organisms in a fermentation broth containing chloride

    ions while the former can be formed either by dechlorinating the

    latter or by placing a micro-organism in a nutrient broth with a

    controlled chloride content.

 

      Similarly in the case Parke, Davis & Co. v. Laboratoire Pentagon

    Lt‚e., 37 Fox P.C. 12, a patent for Chloramphenicol was held valid.

    This product was prepared by a stepwise process which included both

    a biological step and a physical step but it did not include a

    chemical step.

 

      There are many analogies which can be drawn between the anti-

    biotic of Parke, Davis patent and the vaccine claimed here. They

    are both vendible products, they are both prepared by biological

    and physical processes and they both have therapeutic properties.

    Both the antibiotic and the vaccine in their pristine product state

    are substantially inert. It is in use that their separate therapeu-

    tic properties which may be manifested by chemical or biological

    reactions are exhibited. However it is not such use which is being

    claimed; it is the product in its pristine state which is claimed.

 

      The Examiner appears to be rejecting the product claims on the

    basis that the attenuated virus therein, can undergo further biolo-

    gical reaction. However in the state in which it is claimed it is

    substantially inert. That it might undergo further biological

    reaction in use is irrelevant. To be consistent, the office would

    have to reject claims to any substance which is capable of further

    reaction. To take a spectacular example, a claim to an explosive

    compound would have to be rejected because the explosive remains

    inert under only a very narrow range of conditions and the risk of

    disintegration may be quite high. However there is no doubt that

    new and unobvious explosives are patentable.

 

      In summary, the Examiner has not shown that there is any

    substantial difference between an antibiotic and the vaccine claimed.

    Without such a showing the Examiner completely ignores jurisprudence

    and construes Section 2(d) in opposition to the construction made

    thereupon by the courts. The Examiner has failed to make a case             

    against the vaccines being claimed and applicants feel that the

    rejection which he has raised should be withdrawn.

 

    This invention relates to a vaccine against distemper containing a

 

live, attenuated, distemper virus, as will as the process for the manu-

 

    facture of such a vaccine. Claims 1 and 6 read as follows:

 

Claim 1 - A process for the manufacture of a vaccine obtained from

          a distemper virus attenuated by at least 50 successive

          passages in the culture tissues of dogs' organs, for

          the immunization of mustelines against distemper, process

          wherein the attenuated distemper virus is passed through

          at least 10 successive passages in the culture tissues of

          mustelines.

 

Claim 6 - A vaccine for the immunization of mustelines against dis-

          temper, characterized by a content of distemper viruses

          which have been attenuated by at least 50 successive

          passages in culture tissues of dogs' organs, and which

          have then been passed through at least 10 successive

          passages in the culture tissues taken from the tissues

          of mustelines.

 

            At the outset the Board would like to make it clear that the Exami-

          ner's actions in this case were in conformance with Patent Office guide-

          lines relating to the patentability of inventions involving living matter.

          Of fundamental importance is the difference between discovery and

          invention. Creations or products under the laws of nature are regarded as

          being mere discovery; the existence of which man may discover but which

          he could not have invented. As utility is a prime requisite of a patentable

          invention, nothing is invented that can be the subject of a patent until

          a discovery or a formulation of an idea of an end has been united with a

          mode of application so as to produce useful results (Gerrard v. Carey,

          (1926) Ex. C.R. 170 at 178), in terms of either a new and useful thing

          or result or a new mode of producing an old thing or result (Lane-Fox v.

          Kensington & Knightsbridge Electric Lighting Co (1892) 9 R.P.C. 413 at 416.

          Jurisprudence and long standing practice has established that subject

          matter based on the discovery of a vital process, force or phenomenon of

          nature, can be the basis of patentable subject matter, provided some

          artificial result or effect is produced and controlled by the interven-

          tion of man, even though it depends partly or mainly upon the function or

          result produced by living matter, and provided it is practically useful

          even though solely in connection with an inherent response of a living

          thing.

 

          In Continental Soya v. Shorts Millings (1942) 2 Fox Pat C 103 the

          Supreme Court of Canada held that: "... manufacture or composition of

          matter in Section 2(d) of the Patent Act includes a product, which, as

          well as the process by which it is obtained, may be patentable, if it is

  new and useful." The subject matter at issue in this case depended upon

  the use of an enzyme as a bleaching agent in a process for making bread.

  This is held to be a manifestation of man's control over the use of the

  enzyme in a process. In any event the Supreme Court held that the use

  or effect of the enzyme was entitled to the same protection as the use

  or effect of the hormone in the Banting patent.

 

  In American Cyanamid v. Frosst (1965) 2 Ex. C.R. 355, the claims in

  dispute involved living matter and, although numerous defences were

  raised by the alleged infringer, the patentability of the antibiotic was

  not in contest. The decision of Mr. Justice No‰l in this case describes at

  length the production of antibiotics made by processes including living

  matter; yet whether it is subject matter proper for a patent was not

  questioned.

 

 Finally, in the Parke Davis v. Laboratoire Pentagone S.C.C. (1968)

  37 Fox Pat. C. 12, the Supreme Court of Canada considered an appeal dealing

  with the infringement of a patent for an antibiotic which was produced by

  a living micro-organism known as streptomyces venezuela. Again, there

  was no question as to the patentability of such subject matter. Moreover,

  the practice of United States, Great Britain and other major Patent Offices

  is to patent such inventions and the Courts have not been reluctant to

  support the validity of these patents... Also, of significant importance

  in this decision the Supreme Court of Canada held that, a chemical substance

  prepared by a fermentation process followed by purification of the sub-

  stance with chemical solvents, or by absorption, is a product of a chemical

  process within the meaning of Section 41(1) of the Patent Act.

 

Consequently, the basic, question which must be decided is whether

  the subject matter of this application falls within Section 2(d) of the

  Patent Act and satisfies the well established prerequisites which apply

  to the subject matter of a patentable invention whatever the nature of

  the subject matter, and it can be taken as settled that each kind of

  subject matter has equal status and rights as a patentable invention

  unless the statute dictates otherwise; e.g. Section 41(1) of the Patent

  Act. That is, the principles and criteria governing what is a patentable

  invention within the definition must be applied equally, not piecemeal,

  in respect of every kind of subject matter.

 

      The term living organism, in its broadest and most popular defini-

  tion, covers every self-synthesising or self-reproducing organic entity

  from complex mammals down to the simplest organism. But, it is a disputed

  question among experts as to whether viruses do in fact fall within this

  category in view of their non-cellular structure and lack of a metabolic

  system, features which distinguish them from all other organisms, and,

  according to some opinions, justify defining them as inanimate forms

  of matter. However, since they share with the higher organisms the

  nucleic acid mechanism of genetical replication, and can be deemed to

  have delegated their metabolism to the cells which they parasitize,

  there are sufficient grounds for regarding them for present purposes as

  living even though decidedly border line.

 

As of interest, in Swifts & Co.'s application (1962) R.P.C. 37,

  the court found that the British Patent Office did not have authority to

  reject an application for a method for tenderizing meat comprising the

  injection of enzymes into animals before slaughter.

 

      Also, of interest, in Virginia-Carolina Chemical Corporation applic-

  ation (1958) R.P.C. 36, the court held:

 

      At one time it seems to have been thought that any operation

  which involved living organisms was excluded from the definition

  of invention. That this was unjustified is apparent from the

  judgment in Commercial Solvents Corporation v. Synthetic Products

  Coy., (1926) 43 R.P.C. 185, and from the considerable number of

  patents granted in respect of the preparation of antibiotics.

  The increasing use of naturally occurring organisms for initiating

  or controlling or modifying manufacturing operations has wholly

  outmoded as a rule of thumb guide a restriction of patentability

  to inanimate matter. In the case of Standard Oil Development

  Company's Application, (1951) 68 R.P.C., p. 114 (See p. 115 at

  line 53), I suggested a test which may be useful, namely, an

  isolation of the end product of the alleged invention. If to

  secure this the development of living animal or vegetable matter

  by the operation of natural laws is essential, the applicant

  cannot claim to have invented it nor the means of procuring it.

 

  The prerequisite of novelty, an objective consideration, need only

  be considered to establish what the subject matter in question is, having

  regard to the state of the related prior art, and is not in question in

  the present case. Also the prerequisite of unobviousness, a subjective

  consideration, is not in question in the present case. In the case at

  point, involving living micro-organisms, utility is usually the critical

prerequisite to be considered, particularly as to whether the vital

activity of the subject matter can. be controlled and put to practical

use by the intervention of man.

 

   The established criteria of a useful invention (utility are whether

the subject matter is practically useful in a useful art (manual or pro-

ductive) as distinct from the fine art (practising professional skills

having judgemental content, intellectual meaning and aesthetic appeal).

and particularly whether it is operable (reproducible and controllable)

so that the desired result inevitably follows whenever the subject matter

is worked or used by its users. Moreover, the subject matter must be

beneficial to the public. (Wandscheer v. Sicard, (1946 Ex.C.R. at 112

and 1948 SCR 1; and Mailman v. Gillette Safety Razor, (1932) Ex.C.R.

at 54 and (1932) SCR at 724).

 

   On a consideration of the application at hand the subject matter

is in no sense to be considered a fine art, and lies in a useful art

(manual or productive). Moreover, any advance in this field is inherently

beneficial to the public provided it can be controlled.

 

   Hence, the critical question in the present case is whether the

subject matter is operable (reproducible and controllable). In the

present case the activity of micro-organisms is created in an environment

established by the hand of man through a series of cultivations and

treatments in a controlled manner. It is also established that the

vaccine can be produced in a manner as disclosed in the specification,

for when given the micro-organisms and the appropriate ~~~ditions the

desired result is produced; thus enabling a person skilled in the art

to produce the invention after the monopoly expires. On this point and

of significance is the principle set out by the Court in N.R.D.C's

ration (1961) R.P.C. 147 that: "A distinction has necessarily to

bo drawn between cases of this class (plants) and cases of methods

employing micro-organisms; ... for in the latter class of cases the

process is analogous to a chemical process in that, given the micro-

organisms and the appropriate conditions, the desired result inevitably

follows from the working of the process: see Szuec's case (1956) R.P.C. 25."

(emphasis added)

 

   Of importance is the responsibility of the Commissioner of Patents

as held by the Supreme Court of Canada, in Vanity Fair v. Commissioner

of Patents (1939 S.C.R. 24 at 28, that: "The Commissioner of Patents

ought not to refuse an application for a patent unless it is clearly

without substantial foundation." (emphasis added)

 

In the circumstance, therefore, assuming novelty and unobviousness,

the Board is satisfied, having regard to the present state of the law,

that the Commissioner ought not to refuse this application since there

is no apparent reason to exclude the subject matter from patent protection,

as not within the meaning of invention under Section 2(d) of the Patent

Act.

 

   The Board recommends that the decision of the examiner, to refuse

the application on the grounds that it does not represent a patentable

invention according to Section 2(d) of the Patent Act, be withdrawn and

that consideration be given as to whether the vaccine product claimed

is governed by Section 41(1) of the Patent Act. Attention is directed

to the Supreme Court of Canada's decision, Parke Davis v. Laboratoire

Pentagone, as noted herein.
