Section 2:  Dental Identification of Human Remains

 

A labelled ceramic chip is placed in the teeth of bones of the human

body so it may be identified after air crashes or other disasters.  The

method of insertion was held to be beyond the scope of Section 2

Rejection Affirmed.

 

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

 

Patent application 223,202 (Class 83-30), was filed on March 25, 1975,

for in invention entitled "Positive Identification Method And Structure"

The inventor is Philip L. Samis.  The Examiner in charge of the application

took a Final Action on September 22, 1978, refusing to allow it to proceed

to patent.  In reviewing the rejection, the Patent Appeal Board held a

Hearing on February 13, 1980, at which the Applicant was represented by

Mr. R. Mitchell.  Dr. Samis was also present.

 

The subject matter of this application is a system of identifying human

beings and animals.  A miniature information carrier, such as a ceramic

chip, is buried in a hard portion of the body, such as a tooth.  If the

individual is killed in an airline crash, for example, his body may be

identified by the chip.  Figures 2 and 7 reproduced below are representative of

what is involved.

 

(see formula I, II)

 

The plaque 10 is shown embedded in the tooth  The purpose of pin 34 is

to assist in detecting the location of the plaque by radiographic procedure.

       In the Final Action the examiner rejected claims 1 to 15 as directed to

       "subject matter outside of the scope of Section 2 of the Patent Act."

       Claims 1 to 15 relate to the method of implanting the plague in a "highly

       mineralized portion of the body." Claims 16 to 26 directed to the carrier

       or plague were said in the Final Action to be allowable.

 

       In response to the Final Action the Applicant quoted numerous court

       decisions, and stated (in part):

 

...

 

       ... The step of drilling a hole in the enamel of a tooth when

       there is no decay in the immediate area of the drill hole or

       in the area prior to the drilling of the hole does not result

       in the treatment of that tooth. If the tooth as not diseased,

       then how can it be said that the drilling of a hole..., the

       placing of a tag..., and the capping of that hole is a treatment

       of that tooth. The person drilling the hole in the tooth is not

       exercising judgment in a professional manner to treat or cure

       the tooth, but merely as a means to an end, that end being the

       identification of the body.

 

       Applicant insists that he is not by his method treating the

human body or carrying out surgery in the medical sense.  The

method including the step of drilling a hole in a tooth meets

the definition of "art" or "operation" defined in Lawson v Com-

missioner of Patents.

 

...

 

The results of the method are not improved by one's professional

skills in carrying out the step.  The hole in the tooth can be

drilled by a dentist or by anyone capable of handling a dental

drill.  It is also contemplated, although not described in the

present application, that a small jig could be provided for con-

sistently carrying out the step of drilling the hole in the tooth

 

...

 

It is believed that it is settled in Canada that in order for a

process or method to be excluded from patent protection under

Section 2(d), it must be to a medicine or surgery in the strict

sense.  That strict sense is in the sense of treatment for curing

diseases.

 

The cases certainly do not support the Examiner's contention that

"Drilling a hole is an operation, and when one of the starting

materials is a living body the operation is of a surgical nature"

Certainly, the terms "medicine" and "surgery" must be, under

Canadian practice, interpreted in the strict sense and not in

the broader sense which the Examiner attempts.

 

In summary, since the method claimed is one for the purpose

of identification and not for the purpose of treatment of

disease, applicant submits that he is entitled to a patent

under Section 2(d) of the Act for the process of claims 1 to

15.

 

Claim 1 of this application reads:

 

A method for providing positive identification of a living

body comprising:

 

(a) providing a hard, highly mineralized portion of the

body with a cavity,

 

(b) placing identifying intelligence on a radiographical-

ly detectable carrier,

 

(c) embedding the carrier in the cavity whereby the carrier

is completely within the minieralized portion of the

body such as to lend a high degree of heat and impact

protection to the carrier.

 

The question before the Board is whether or not the subject matter of the re-

jected claims is outside the scope of Section 2 of the Patent Act.

 

There was considerable controversy about the term "surgery" as used in the

application.  In the Final Action it was stated that "....the Examiner is

unable to follow the Applicant's reasoning which is directed to some point

concerning medicine.  While surgery might be broadly considered to be a part

of what is sometimes referred to colloquially as the practice of medicine,

this appears rather irrelevant to the rejection of the claims which is, and

always has been, that their subject matter claims the treatment of a living

body by surgery.  Drilling a hole is an operation, and when one of the starting

materials is a living body the operation is of a surgical nature..."

 

On the other hand Mr. Mitchell argues that "....The word surgery, according

to Webster's Third New International Dictionary, is a branch of medicine that

is concerned with diseases and conditions requiring or amendable to operative

or manual procedures.  It is clear that the drilling step of provision

of a cavity in a living being's tooth in the method claimed in the present

application is not a surgical step.  If medicine refers to the fine art of

treating diseases, then surgery is one of those fine arts within the broad

definition of medicine and is considered for the full purpose of treating

diseases.  The step of drilling a hole in the enamel of a tooth when there is

no decay in the immediate area of the drill hole or in the area prior to

the drilling of the hole does not result in the treatment of that tooth...."

 

Further, Applicant maintains that the step of drilling a hole in a tooth

meets the definition of "art" as defined in Lawson v Commissioner of Patents,

1970, 62 C.P.R. 101.  Turing to that decision at page 109 "art" or "manufacture"

are defined as:

 

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

by some physical agent upon some physical object and pro-

ducing 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 con-

sists in the application of physical agents to physical

objects and is then apparent to the senses in connection

with some tangible object or instrument.

 

In Tennessee Eastman vs the Commissioner of Patents (1970) 62 C.P.R. 117

and 1974 S.C.R. 111, after deciding "the application is concerned with a pro-

cess of medical or surgical treatment of living tissues in living bodies

including humans," the Exchequer Court said at 155 (quoted by the S.C. at

114):

 

The method lies essentially in the professional field of

surgery and medical treatment of the human body, even al-

though it may be applied at times by persons not in that

field.  Consequently, it is my conclusion that in the

present state of the patent law of Canada and the scope of

subject-matter for patent, as indicated by authoritative

judgements that I have cited, the method is not an art or

process within the meaning of s.2(d) of the Patent Act.

 

At the Hearing Dr. Samis, the inventor, stated that the identifying tag did

not necessarily require a dentist to implant it in a tooth. He indicated

that any person capable of handling a dental drill could be taught the

necessary technique in a short period of time.

 

In response to the question as to whether or not the application relates to a

"manner of manufacture" Mr. Mitchell agreed that it did not result in a vendible

product. However, he maintains that it is a method which results in a commer-

cial benefit similar to the situation covered by the N.R.D.C. application as

reported in R.P.C. (1961) @134. Further in support of his position Mr. Mitchell

recited a claim from a recently alloyed Canadian patent which relates to certain

methods of testing which require the step of performing a "thoracic duct

fistula" on a patient.

 

We are aware that there are dental procedures in which "posts" are tapped into

the existing tooth root as a base for building the tooth up by acrylic or

other such material. Thus an article is "embedded" in a tooth by a method

similar to that proposed by the Applicant. However since we are only concerned

with Section 2 of the Patent Act we will not comment further on this point.

 

Having studied the relevant decisions of the Canadian Courts, and in particular

Tennessee Eastman (supra) Imperial Industries v Commissioner of Patents

51 S.P.R. (1967), Lawson v Commissioner of Patents (supra) and the jurisprudence

relied upon in them, we believe that the process claimed is unpatentable,

under Section 2 of the Patent Act.

 

In the Lawson decision (supra) at p. 109, it was stated that:

 

I take it as well settled that all new and useful arts

and manufactures are not necessarily included in s. 2(d)

of the Act.

 

The Court also quoted with approval the following passage from National Re-

search Development Corporations application (Australia) [1961] R.P.C, 135,

Dixon C.J. at p. 145:

 

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 use-

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

Chemical Corporation's Application, [1953] R.P.C. 35 at

p.36) - that its value to the country is in the field of econ-

omic 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: sec Maeder v,

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

 

From that the Court concluded:

 

It is obvious from the concluding portion of the above quota-

tion that professional skills are not the subject-matter of a

patent. If a surgeon were to devise a method of performing a

certain type of operation he cannot obtain an exclusive property

or privilege therein. Neither can a barrister who has devised a

particular method of cross-examination or advocacy obtain a

monopoly thereof so as to require imitators or followers of his

methods to obtain a licence from him.

 

It seems to me that a method of describing and laying out

parcels of land in a plan of subdivision of a greater tract of

land in the skill of a solicitor and conveyances and that of a

planning consultant and surveyor. It is an art which belongs to

the professional field and is not a manual art or skill.

 

In the Imperial Chemical case (supra) Mr. Justice Cameron concluded that the

term "medicine," (and by analogy "surgical") are to be interpreted broadly, in

the ordinary vernacular sense. Thus:

 

The word "medicine" and the word "medication" as so used are

not terms of art. Instead they are swords of the vernacular,

of common parlance, and must therefore be interpreted in

their ordinary sense.

 

and

 

the correct judicial approach to the question has been

definitively stated by the Supreme Court of Canada. (See

Parke, Davis & Co. v Fine Chemicals of Canada Ltd. 30 C.P.R.

59 at p. 66 where Martland, J., said, "I agree with Thurlow,

J. [27 C.P.R. 117] that the word 'medicine' as used in

s. 41 of the Act should be interpreted broadly.... ).

 

When we look at Applicant's processes we find that it covers drilling into

a patient's tooth and implanting an object in it. It is true that the object-

ive is not to stop decay in the tooth, but we believe it is still essentially

a dental procedure. Dr. Samis said at the Hearing that any person capable

of handling a dental drill could be taught the necessary technique in a short

period of time, but we do not think that is germane to the question before

us. Drilling teeth, embedding a foreign object in it, and properly sealing

the cavity requires precision and care. One must avoid infection, destruction

of the tooth nerve, haemorrhaging, after effects and the like. In some instances

anaesthetics may be required. One should assess whether the tooth is in fit

condition for the operation in the first place. All this comes within the

skill and competence of a qualified dentist. Indeed in most, if not all

jurisdictions within Canada, it can legally be performed only by a dentist.

See The Dentist Act of Quebec, R.S.Q. 1964, c. 253, s. J.34 or The Dentistry

Act of Ontario, R.S.O. 1970, c. 108, s. 21.

 

Applicant's argument is the same one as that used in the Tennessee Eastman

case, 62 CPR 117 at 124, and rejected by the court:

 

The Examiner has suggested that the success of the process

is dependent on the skill and knowledge of the physical and

the physiological processes of the patient. Although the

success of the method may defend somewhat on the persons using

the compositions, the disclosure amply outlines the expect

procedure on, for example, page 7, for applying the adhesive

to form a firm bond. A physician may normally apply the method,

however, it is not considered that any skill, knowledge or

training would be required such as that demanded of a physician.

Certainly a physician is not the only person who may close a

wound by suturing as it is common for athletes to be treated

by others such as trainers, etc., to close wounds obtained

during sport contests. The procedure of the instant invention

thus may be readily followed by others and does not require the

skill and knowledge of a physician to use and may be employed

by non-professional medical people....

 

The Exchequer Court's answer to that was given at p. 155:

 

...The method lies essentially in the professional field

of surgery and treatment of the human body, even though

it may be applied at times, by persons not in that

field. (underlining added)

 

In the present case we are convinced that the method claims lie essentially

in the field of dentistry and would normally be performed by dentists. Con-

trary to what Applicant contends, we believe the success of the operation

would depend on the professional. skills of the dentist. We are not consider-

ing a process for drilling disembodied teeth, but those in the mouth of

living human beings, with all the risks and dangers that that involves.

 

In deciding that the method in question was not an art or process within

the meaning of Section 2, Mr. Kerr quoted from several earlier cases, including

(at p. 129) Lawson v Commissioner of Patents; National Research Development

(also at p. 129); C & W's Application (at p. 130-132); G.E.C.'s Application

(at p. 132); Maeder v Busch (at 133 to 135 and 151); Maeder v Ronda

(at p. 135) and others. At p. 130 he said:

 

Early in the development of patent law in England it was

accepted that a manner of new manufacture may be a product

or may be a process that can be used in making something

that is, or may be, of commercial value, a vendible product.

Concurrent with that concept was the principle that

a method of treating any part of the human body does not

afford subject matter for a patent.... (underlining added).

 

At p. 135: ... in Maeder v "Ronda" Ladies Hairdressing Salon and Others

[1943] N.Z.L.R. 122, Myers C.J., and Johnston J. ...held

that a process, to be patentable, must at least have relation

in some way to the production of an article of commerce.

(underlining added)

 

That brings us to Mr, Mitchell's contention that the process has commercial

benefits. In Tennessee Eastman, at p. 154, Mr. Kerr said:

 

In my view the method here does not lay in the field of the

manual or productive acts nor, when applied to the human body,

does it produce a result in relation to trade, commerce or

industry, or a result that is essentially economic. The

adhesive itself may enter into commerce, and the patent for

the process, if granted, may also be sold and its use licensed

for financial considerations, but it does not follow that the

method and its result are related to commerce or are essentially

economic in the sense that those expressions have been used

in patent case judgements. The method lies essentially in the

professional field of surgery and medical treatment of the

human body, even although it may be applied by persons not in

that field. Consequently, it is my conclusion that in the

present state of the patent law of Canada and the scope or

subject matter for patent, as indicated by authoritative

judgements that I have cited, the method is not an art or

process or the improvement of an art or process within the

meaning of s. 2(d) of the Patent Act.

 

This particular passage was repeated in the affirming decision of the Supreme

Court in 8 C.P.R. (2d) 202 at 204.

 

Mr. Justice Kerr also relied, at p. 134, upon Maeder v Busch (1938) 59 C.L.R.

684, and quoted a lengthy passage including the following:

 

But the object (of the invention) is not to produce or aid the

production of an article of commerce. No substance or thing

forming a possible subject of commerce or a contribution to

the productive arts is to be brought into existence by means

of or with the aid of the process.

 

In the present case the "product" or result of the process are human beings,

and not something which is sold in the market place. We are consequently

satisfied that Applicant's process does not produce a result "That is essential-

ly economic" in the sense that that term is used in patent law. Fees may be

paid to those who carry out Applicant's process, but those fees differ in no

respect from those paid medical practitioners or surgeons for their services,

which clearly fall outside the scope of Section 2. That argument would not

apply, of course, to the product of claims 16 to 26, which were considered

allowable by the Examiner.

 

We have concluded in the present case that the method does not lie "in the

field of the manual or productive arts, nor when applied to the human body

does it produce a result in relation to trade, commerce or industry or a

result that is essentially economic" (Tennessee Eastman per Kerr J. at p. 154).

It is a fine art, the success of which depends upon the skip of the dentist

performing it. We believe claims 1 - 15 should be refused.
