   This decision deals with a request for review by the

Commissioner of Patents of the Examiner's Final Action dated

July 22, 1971 on application 070,459. This application was

filed in the name of Dick L. Rehnstrom and refers to

"Hydraulically Operated Device for Cutting Trees, Logs and

the Like".

 

The petition reads as follows:

 

1. THAT Your petitioners are the patentees of Canadian

Patent 723,956 granted on the twenty-first of

December 1965 an invention entitled "Hydraulically

Operated Device for Cutting Trees, Logs and the Like"

 

2. THAT the patent is deemed defective or inoperative by

reason of insufficient description or specification

and by reason of patentee having claimed more and less

than he had a right to claim as new.

 

3, THAT the respects in which the patent is deemed

defective or inoperative are as follows:

 

(a) The specification, in paragraph one on the first

page of the disclosure of said issued patent 723,956

broadly recites the invention as relating to "apparatus

for cutting trees, logs and the like and comprising

at least one cutting member movable when actuated upon

by a hydraulic cylinder" but instead, the invention

is more narrowly and correctly concerned with "a

cutting member mounted on a frame and movable relative

upon actuation of power means" and having the cutting

blade and frame arranged such as to provide a jaw "of

the open mouth type" for receiving a tree to be

severed by particular movement of the one relative to

the other, i.e. "in a direction normal to the length

of the article".

 

(b) The specification, in paragraph two of the issued

patent, recites the invention as consisting of "apparatus

which is designed in such a way that during a cutting

operation each point on the blade of the cutting member

carries out a movement which has a component in the

longitudinal direction of said blade" but more correctly

it is a point "on the cutting edge of the blade" which

has a component of motion parallel to such "cutting

edge". Also, the invention is more narrowly directed

to a severing device of the "open mouth type" illustrated

in the drawings.

 

(c) In the paragraph of the specification immediately

following the list of drawings, with reference to the

issued patent, the apparatus is described with reference

to the drawings, as being illustrated in various manners

in various positions and more correctly such illustration

is with respect to "Figure 1" and it is the "jaw" which

is illustrated in an "open position" ready to receive

a log. In the same paragraph the point is referred to

in reference to the "blade" but more specifically should

be referred to as being "on the cutting edge" of the blade.

 

(d) The paragraph next following that last discussed

above, describes the link system as comprising "two link

pairs" but more accurately, and what is illustrated is

"a pair of links 4a and a pair of links 4b.

 

(e) The fifth last paragraph incorrectly suggests that

the choice of a suitable shape for the "blade",may be

chosen to modify the mentioned advantageous effect but

instead, it la the shape of the "cutting edge" which is

of concern. Reference is also made to the portion

located "inside the blade" and such portion, however,

is actually located in a position relative to the "cutting

edge". The same paragraph also too broadly describes the

 

    actual location of the grooves which are located

    perpendicular to the "cutting" edge of the blade.

 

    (f) The second last paragraph of the specification

    broadly describes horizontal attitude of the cutting

    apparatus by virtue of being suspended but more

    specifically such position results from "being suspended

    at its center of gravity

 

    (g) Claim 1 of said patent 723,956 claims more than

    the patentee had a right to claim by broadly being

    directed to a particular movement of a cutting blade

    in a shear during severing. The particular movement

    consists of "a component in the longitudinal direction

    of said cutting blade" and such movement is provided

    b,y having the cutting member "mounted in a link system

    having two sets of links". Mounting of a shear blade

    on a frame by two links providing motion in a blade with

    "a component in the longitudinal direction of said

    cutting blade" is known in Canadian Patent No. 529,975

    issued September 4, 1956.

 

    The error of claiming more arose because of the patentee

    having no knowledge of the existance of the Canadian

    patent 529,975.

 

    In the prosecution terminated by the Final Action the

 

    examiner rejected the application for reissue on the following

 

    grounds:

 

    (a) Claims 1 to 21 are not directed to the same

    invention as the claims alloyed in the original

    patent and which claims are presently on file;

 

(b) There is no error in the original claims through

    applicant having claimed more than he had a right to

    claim in view of Canadian Patent 529,975, that has

    come to his attention;

 

    (c) The petition fails to adduce any evidence of intent

    to claim all the features of claims 1 to 21 presented

    in the reissue application, and

 

    (d) The petition is defective and incomplete.

 

    In this action the examiner stated: (in part)

 

 Comparing claims 1 and 22 for example, claim 1 contains

    the following limitations no present in claim 22:

 

      (a) said cutting member and frame defining a jaw having

    an open mouth

(b) said links being disposed so as not to traverse

the bite of the jaw.

 

Claim 1 however omits many of the limitations of claim

22 including "said cutting member ... having the shape

of an oblong plate". Applicant has contended in the

letter of May 6, 1971, page 3; 2nd paragraph that the

shape of the blade is not a feature of patentability.

It is held however that the blade shape is a structural

characteristic and is a patentable feature. Since

neither of claims 1 and 22 therefore is broader than

the other, such claims are deemed to be directed to

different inventions. Section 50 of the Patent Act

states that a reissue may be obtained for the "same

invention" only.

 

The petition fails to adduce any evidence of intent

to claim all features of claims 1 to 21 presented in

the reissue application. In the letter of May 6, 1971,

page 6, applicant has argued that the presence of

features in the disclosure of the application as originally

filed is evidence of what applicant intended to cover.

It is held however that the inclusion of features in

a disclosure does not provide sufficient evidence to

support applicant's contention that he intended to

claim them. In fact a review of the prosecution of

the original patent verifies that at no time did

applicant attempt to claim or show any intent to claim

the features of claims 1 to 21.

 

Item 2 is now defective since by introducing the original

claims it cannot be said that patentee "claimed more

and lees" than he had a right to claim as new. Section

50 of the Patent Act provides for reissue if an applicant

claims more or less and it is not seen how claims could

be defective because of claiming more and less in the

original. Applicant has attempted to overcome this

problem by inserting claims to different subject matters

in the reissue (which has been dealt with in ground A

above.) In any case the submission of the original

claims in the reissue is evidence that applicant considers

the patent is not defective by having claimed "more and

less".

 

Applicant has failed to fully state in the Petition in

what respect he considers the patent defective or

inoperative in the light of which every new claim of

claims 1 to 21 have been framed. In this respect

attention is directed to Rule 81 of the Patent Rules.

 

   In the response of December 21, 1971 the applicant went to

great lengths, citing twenty-four patents, to show that different

elements of the claims are old and should not be considered as

essential features.

 

   The applicant maintains that the application for reissue

is self-evident of error and compares the teaching of Canadian

Patent 529,975 to show that there is error in that applicant claimed

more than he had a right to claim as new. The error was in

complete inadvertence as the applicant was not aware of the

patent in question. The applicant also maintains that he has

a right to claim other features, such as, "a crane beam" in that

a crane beam is well known in the art.

 

Applicant also stated: (in part)

 

Ground D of the objection in the Official Action

concerns defective and incomplete petition. Items H

and I which are referred to as being cancelled by

way of applicant's August 7, 1970 letter, refer to the

claims in the corresponding U.S. patent which has

since been re-issued. Because of the cancellation of

paragraphs H and I, it is indicated that item 2 is now

defective since the patentee states therein claiming

more and less than there was a right to claim as new.

Because of the cancellation in the petition of items

H and I, the words "and less" may be deleted or

considered inapplicable since there is only one

independent claim and which claim claims more than

applicant has a right to claim. The petition is,

admittedly,poorly drawn for reasons as previously

set forth, namely, basing the Petition on re-issue of

the corresponding U.S.patent. However, it is deemed,

in its present form, sufficient to show the respect~

with which the patent is deemed defective or inoperative,

namely, being too broad because of having a claim

which reads on the Disclosure of Canadian Patent 529,975.

 

   Having carefully studied the petition the Board has come to

the conclusion that the claims of the original patent fail to

explicitly set out his invention since it is evident that the

claims are too broad in view of Canadian Patent 529,575. It

follows that the applicant may not retain the patent claims as

they would defeat the object of the petition.

 

   The first round of rejection that, "Claims 1-21 are not

directed to a same invention as the claims allowed in the

original patent," (refiled as claims 22-25 of the present

application) is not well founded. On considering what is meant

by the same invention under reissue, the court in Northern Electric

Co. Ltd, v, Photo Sound Corporation (1936) SCR 649 that,

"... the reissue patent must confirmed to the invention which

the patentee attempted to describe and claim in his original

specification, but which owing to 'inadvertence, error or

mistake', he failed to do so properly; he is not to be granted

a new patent but an amended patent." (emphasis added) This

statement was also cited by Martland J, of the Supreme Court of

Canada in Curl-Master Mfg. Co. Ltd. v.Atlas Brush limited (1967)

SCR 527.

 

   An allowable claim must include, "... power means pivotally

connected to the cutting member ...," as this is necessary for

a complete claim for operativeness. The characteristic in the

original claims, "... having the shape of an oblong plate," may

be deleted from the claims in that it was not added to avoid the

prior art as the prior art shows a blade of this shape; also since

the important limitation is that any point on the cutting edge

of the blade carries out a movement which has a component in the

longitudinal direction of said cutting edge. Assuming the new

claims are of different scope, the Board is satisfied that there

is no evidence of newly discovered subject matter in the new

claims and that the new claims cover substantially the same

invention as that for which the patentee sought to patent in

the original specification.

 

   The second ground of rejection that, "There is no error in

the original claims through the applicant having claimed more

than he had a right to claim as new in view of Canadian Patent

529,975, and at the same time maintain the original claims,"

 

   The third ground of rejection is that, "The petition fails

to adduce any evidence of intent to claim all the features of

claims 1-21 ..." The applicant may restrict the claims of the

patent to more clearly cover the real invention by setting out

the feature of, "the open jaw type mechanism having links so

arranged as not to transverse the bite." The addition of

further limitations in independent claims would also not appear

to offend the intent of the petition since there is no evidence

of fraudulent intention or that the inventor did not intend to

obtain a patent for his real invention which through inadvertence

his agent failed to do.

 

   The fourth ground of rejection that, "The petition is

defective an incomplete," is no longer an issue since the

applicant has cancelled items H and I from the petition and in

response to the Final Action the applicant states, "... the words

and less may be deleted or considered inapplicable." The remainder

of the petition has been considered on its merit.

 

   The applicant asked, "since when does the shape of anything

become a patentable feature"? In answer to this it is well

established that the shape of an article may become a patentable

feature when the particularized shape subserves some new and

unexpected mechanical function. Applicant also states that,

"... it is evident reissues under present practice in office

policy, can only be obtained for the purpose of adding claims

of narrow scope ..." This is an erroneous interpretation since

reissues with broader claims are valid providing the petition

  and changes meet the requirements of Section 50 of the Patent

  Act and principles established by jurisprudence. The Court in

  Withrow v. Malcolm 1884 6 OR 12, held that an applicant has a

  right to claim in a reissue could have been claimed in the

  original providing specific conditions are met. The amended

  petition does not make provision for the issue of broader claims.

 

In summation the Board finds: (a) the patent claims,

  present claims 22-25, are not allowable; (b) the addition of the

  characteristic, to the original claims, that the sets of links

  are arranged so as not to transverse the bite of the open jaw

  type mechanism during the cutting operation, while omitting

  the feature that the blade has the shape of an oblong plate,

  are permissible. In other words it is suggested that a claim,

  such as claims 1 and 2 when combined, or any similar claim, may

  be considered allowable. However, the reference in claim 1 to

  at least one cutting member may be questioned.

 

                                R. E. Thomas,

                                Chairman, Patent Appeal Board.

 

      I concur with the findings of the Patent Appeal Board and

  refuse to allow claims 22-25. Claims 1-21 are refused in their

  present form, however, claims drawn according to the guidelines

  set forth may be considered allowable. The applicant has six

  months in which to appeal this decision in accordance with

  Section 44 of the Patent Act.

 

                                 Decision accordingly,

 

                                 A. M. Laidlaw,

                                Commissioner of Patents.

 

  Dated at Ottawa, Ontario,

  this 22nd day of February, 1972.

 You are being directed to the most recent version of the statute which may not be the version considered at the time of the judgment.
