                    COMMISSIONER'S DECISION

 

OBVIOUSNESS: Roll Label

 

The invention is for a roll of labels which are precut and preprinted

so they can be readily affixed to plastic or glass containers. This

application is a division of the labelling machine used therewith. It

was decided sufficient ingenuity was exhibited to allow the claims.

 

Rejection: Reversed

 

The Final Rejection of patent application 094,016, (Class 40/23) was re-

(erred to the Patent Appeal Board for consideration. There was a hearing

before the Board on February 18, 1976, at which Mr. O'Gorman made oral

submissions on behalf of the applicant. The inventor is Herbert LaMers,

and the title given to the application is "Labelling Apparatus."

 

The invention claimed in this application is a roll of labels adapted to

be used in the labelling machine protected by Canadian patent 860,753,

January 12, 1971. The application is a divisiea of the one which matured

into that patent, and the same inventor is common to both. During the

prosecution of the patent, the examiner held that the label roll was for

a different invention than the labelling machine, and applied Section 38

(though the report incorrectly referred to Section 36). The divisional

application resulted from that objection.

 

The labels and equipment are used in high speed packaging of a variety of

goods, such as plastic or glass containers for detergents, beverages and

foodstuffs. The labels are preprinted on the roll, and precut so that they

may be readily punched out from it when they are affixed to the containers.

Both edges of the roll contain sprocket holes used to feed the roll forward.

  In the Final Action the examiner refused the application for lack of

  patentable subject matter in view of certain prior art references, and

  common general knowledge. The references cited are as follows:

 

Canadian Patent          414,033   July 20, 1943    Sherman

                             694,818   Sept 22, 1964     Mitzer

 

  United States             2,259,358  Oct. 14, 1941    Templeton

 

 French Patent              1,095,874  July 7, 1955       Burgner

 

  In that action the examiner made the following objections:

 

  Applicant by his amendment to the claims, which are directed to

  a roll of paper, now includes therein apparatus limitations and

  operational steps carried out by the apparatus. These limitations

  are admitted by applicant's argument "the claimed subject matter

  is defined and limited in part by the apparatus with which the

  subject matter is used". However it is held that claims directed

  to a supply of material such as a roll or strip of paper cannot

  rely for novelty, and therefore invention, either on structural

  features of a particular apparatus in which it is proposed to

  use the paper or on details of some operating step carried out by

  such an apparatus. To be patentable, such claims must not only

  define structural features by which the strip or roll distinguishes

  from all other previously known strips or rolls but such novel

  structural features must be unobvious and ingenious to an extent

  meriting the grant of monopoly privileges. Neither the supplying

  of a precut strip to suit a modified cutterless labeler, nor

  the common knowledge roll form of the supply can be seen to be

  of any patentable significance. Claims 1 and 4 to 7 therefore stand

  rejected. Furthermore claims 2 and 3 specifying U-shaped sprocket

  holes and captive tabs add nothing of an inventive nature to

  claim 1 and are also rejected.

 

  It is maintained that applicant, by removing the cutting stage

  from the sequential multi-operation machine of Sherman creates a

  problem in that his modified device will not function with the uncut

  supply strip of Sherman. This is the only "problem" solved by the

  precut web defined. It is further maintained that the concept of

  incorporating pre-cut in a Sherman type supply strip to suit a Sherman

  type of device which has been modified by eliminating the cutter

  therefrom lacks inventive ingenuity over Sherman. Whether the cutting

  is carried out on the labeler as in Sherman or geographically separate

  from the labeler as in the instant disclosure is an obvious optional

  matter of choice. However having made the choice, it is not only

  obvious but essential for the operation of the modified labeler that

  the supply strip be precut. In these circumstances, where nothing unobvious

  results, the precut supply strip is not per se unobvious or inventive.

 

  Considering the structural limitations recited in the claims, as

  opposed to the apparatus and operational limitations mentioned above,

  the only features defined in claims 1 and 4 to 7 which are not taught

  by Sherman is the end to end extent of the cuts and the "roll" form

 of the supply. As stated above, the mere supplying of a pre-

 cut strip to suit the modified cutterless labeler is of no

 patentable merit. Furthermore the roll form of a label supply

 is common general knowledge and its recitation adds nothing of

 an inventive nature to these claims.

 

 It is obvious that the notched knife of the cutting die 28 as

 shown in Figure 6 of Sherman will produce the well known non-

 continuous outline cut exactly as defined in the claims. Thus,

 apart from the end to end extent of the cut portion and the roll

 form of the strip, the Sherman patent shows all of the structural

 details defined in claims 1, 4, 5, 6 and 7. The applicant in the

 original disclosure teaches that "while a piston operated plunger

 can be used...a variety of other types of apparatus can be used...

 or a blast of air can be used to detach the label from the

 surrounding web". Applicant's strip therefore is not designed

 exclusively to suit a plunger as may be inferred from the wording

 of claims 1 and 7. Further, the original disclosure merely

 states that the strip is of plain paper and that the ends of the

 cuts are spaced from each other to form brides 122 each of a

 width W. There is no teaching either that the paper has one of its

 surfaces especially "adapted for receiving adhesive" or that the

 widths of the "bridging means" are predetermined or pre-selected

 in any way to suit any special type of apparatus, as implied by

 claims 1 and 7. These features therefore cannot be relied upon, either

 individually or in conjunction with other features, to define

 invention.     

 

   Neither the supply of a precut strip to suit a modified cutterless

 labeler as noted above nor the common knowledge roll form of the

 supply can be seen to be of any patentable significance.

 

In the response dated February 2, 1975 to the Final Action the applicant

 stated (in part):

 

 In claim 1, applicant does not specifically rely on the features

 of the apparatus with which the label supply is used or upon

 the operation of that apparatus. Quite to the contrary, the claim

 is drawn to a label supply and to a specific bridging means which

 holds the label within the web remnant. Those bridging means are

 simply defined by reference to the resilient plunger of the apparatus

 in which the label supply is intended for use, whether or not such a

 resilient plunger is actually used. Thus, the claim does not include

 features of the apparatus with which the web is used, as positive

 elements but rather only defines the web in terms of the apparatus.

 Applicant believes that this format is clearly proper.

 

 Indeed, it goes directly to the heart of the invention which lies in

 the particular specification of the label bridges which are defined

 in relation to the nature of the article-applying plunger. In this

 regard, it is critically important, not that a resilient plunger can

 be used, but that the bridges have a certain width which is

 specifically defined as that width which permits label detachment by

 a resilient plunger. Reference to a resilient plunger is not

 immaterial or inconsequential, but rather provides a basis for a

 specific description of a positive element of the claim. The phrase

  specifically defines the width of the label supporting bridges

  in terms which go to the heart of the invention. The width of

  the bridges is exactly that which will permit the labels to be

  removed by a resilient plunger.

 

   This is a case where the invention, to a large extent, lies in

  defining the parameters of a structural component of the claimed

  combination in terms of what it is capable of doing. The term

  so defined is structural within these bounds and the aforementioned

  phrase is believed to be of great patentable significance, in

  combination with the other features of the claim. To this extent,

  the phrase is not considered to be any different than the normally

  used and patentably descriptive terms, such as "rotatably" or

  "slidably" mounted, fox example.

 

   and

 

  A number of advantages of the specifically claimed label supply

  have already been disclosed to the Patent Office. To reiterate,

  however, it should be pointed out that insofar as die-cut labels

  are concerned, the claimed subject matter supplies the possibility

  of unlimited label shapes, an advantage not heretofore known with

  respect to label supplies. A further advantage is that the claimed

  label web permits the use of adhesive over the complete surface

  of the labels. Since the prior webs were required to be sheared or

  cut off by some mechanism at the removal station, adhesive out to

  the extreme label edges was not practical due to the fact that it

  would tend to bind or seize the cutting apparatus. Since no

  cutting apparatus is required with applicant's label, due to the

  concept of providing the bridges as claimed, overall adhesive applica-

  tion to the extreme label edges can be practically utilized. There

  are no cutting dies to foul.

 

 Another important advantage of the claimed label supply is that it

  Makes possible the elimination of any cutting equipment required in

  the labeling operation itself. Such cutting equipment not only

  increased the cost of labeling apparatus, but also required maintenance

  and trained operators for the cutting operation. Since the label

  supply as claimed is cut on a different apparatus, the label webs can

  be stock piled and malfunctions in the cutting devices do not require

  shutdown of the complete labeling operation. Certainly, these

  are advantages of the complete labeling system, but they all stem

  from one basic theory: the structure of the web.

 

  and

 

The applicant submits that none of the prior art discloses or

  suggest the need for a label supply structure as set forth in claim 1

  or claim 7 and believes that the claimed subject matter cannot be

  considered obvious, where the concept of both removing a label from

  the web and applying it to an object with the same resilient plunger,

  was unknow until the applicant's own disclosure. In the prior art,

  there is no reason for, or suggestion of a label web in which the

  labels are held by bridging means of a thickness selected to permit

  removal of the labels from the web by a resilient plunger without

  indiscriminate tearing of the label. The applicant therefore believes

  that the Examiner's suggestion that the claimed structure is obvious

  in view of Sherman, or any of the other references, can only be made

  with hindsight, and with the benefit of the applicant's own disclosure.

 

The Sherman Patent relates to an envelope and package addressing apparatus

which applies address labels to envelopes and small packages in a continu-

ing succession. A folded uncut web (or length of paper) with address labels

printed thereon is fed to a reciprocating cutter to score the label area of

the web. The next stage is a heating station where the legend bearing

label is stuck to the envelope, which moves with the web to the punch stage.

At this location a punch press is used to detach the label with its attached

envelope from the web. Claim 1 of this patent reads:

 

In a label applying apparatus, strip feeding means for ad-

vancing a legend bearing strip through successive step-by-step

movements, a unit supply magazine and a unit depository over

which the strip is advanced, a scoring die past which the strip is

advanced for outlining by weakened division lines succeeding

legend bearing portions of the strip to be detached therefrom,

an applicator in registry with the unit supply magazine operative

to adhesively attach an outlined legend bearing portion of the

strip to the uppermost unit in the magazine, and a detaching device in

registry with the unit depository and into registry with which the

attached legend bearing portion of the strip and the unit to which

it is attached is advanced by the advancement of the strip and

operative to detach from the supply strip the legend bearing portion

thereof attached to the unit.

 

The Metzner, Templeton and Burgmer patents disclose web feeding sprocket holes

which are arranged in longitudinal series at the longitudinal margins of

the web. Metzner and Burgmer have their sprocket holes formed of U-shaped

cuts in the web which form tabs or flaps within the cuts. These flaps are

pushed aside when engaged by the sprocket wheel but remain attached to the

web. Similarly Templeton uses a T-shaped cut to form his sprocket hole. Each

of these citations show a "captive tab" arrangement to overcome the problem

of loose paper confetti being displaced from the sprocket holes and clogging

up the equipment.

 

As mentioned previously, the applicant's label supply reel consists of a web with

precut labels therein, and spaced sprocket holes adjacent to the longitudinal

margins of the roll. The problem of clogging with confetti from the sprocket

holes is eliminated by using tabs or "U"-shaped cuts to form the holes.

 

Claim 1 reads:

 

A rolled, pre-printed, precut label supply including an elongated

web supporting labels therein, for use in apparatus adapted to

apply labels to products, said apparatus including means for estab-

lishing a tacky surface to one side of said labels, a reciprocating

resilient plunger means for engaging labels, for passing through

said web and detaching labels therefrom, for carrying labels toward

and applying labels to products, and thereafter withdrawing through

a web remnant, said resilient plunger means having a forward label

engaging face with a predetermined shape, and sprocket means for

transporting said web through said label applying apparatus, said

pre-printed, precut label supply comprising: an elongated single-ply

web in the form of a roll including a plurality of labels and a web

remnant to which said labels are attached, said labels being located

throughout said remnant from one end to the other of said web, said

labels being partially cut from said web remnant by a plurality of

cuts extending completely through said web, the ends of said cuts being spaced

apart to leave bridging means between said labels and said web remnant

thereby to releasably hold said labels in said remnant, said bridging

means having predetermined widths selected to permit the detachment of

said labels by said resilient plunger, transversely to said web remnant,

without indiscriminate tearing of the label, said labels having two

sides, each free from adhesive, one of which sides is adapted for re-

ceiving adhesive and another side which bears printed indicia, and

sprocket holes in said web remnant and extending therealong, said

sprocket holes disposed in said remnant to permit accurate registration

of said remnant and said labels with respect to said resilient plunger.

 

The question to be decided is whether the application is directed to a patent-

able advance in the art.

 

This application is a divisional of Patent No. 860,753, which issued with 19

claims for the apparatus to apply the labels. Operation of the apparatus re-

quires some form of label supply arrangement, and that is the basis for this

application.

 

In the Final Action the examiner maintained that by removing the cutting stage

from Sherman's device, the applicant in fact "creates a problem in that his

modified device will not function with the uncut strip of Sherman." Sherman

uses a folded web supply which has legends imprinted thereon. At the first

stage of his operation Sherman uses a reciprocating cutter to score the

legend-bearing area of the web. Next the web advances to the heating station

where the legend is attached to the envelope and then the web proceeds with

the envelope adhered to the label to the presser head which separates the

legend area from the web. Sherman was concerned with labelling envelopes or

small packages in which the web advances the labelled article through one

stage of machine operation. In order to perform this function Sherman

 fastens the article to the web, and advances it to the punch station. In

 our view there is no indication that Sherman envisaged the use of prepunched

 supply reel or that he would apply the label to an article without moving

 the article via the web to the next stage of operation.

 

 At the hearing it was pointed out by the examining staff that in figure 5

 of Sherman the label supply arrangement shown is nearly identical to the appli-

 cant's. Figure 5 of Sherman is a perspective view of the web as it moves

 through the apparatus. This figure shows the web starting with a legend

 imprinted thereon (3), succeeded by a scored area (36) depicting what occurs

 at the cutting station, and then followed by a representation of a detached

 label adhered to the envelope below the advancing web (at 35). In looking for

 similarity between Figure S of Sherman(which shows only one scored label)

 and this application, we note that figure 5 of Sherman does not show a "rolled

 precut label supply" such as that contemplated by the applicant. In Sherman

 there is only one precut label at a time, and that immediately before it

 is affixed to the envelope.

 

In developing his invention the applicant devised an apparatus for applying

 labels, and in conjunction therewith a label supply. The apparatus required

 a special label supply arrangement and the applicant developed a prepunched

 label reel for that purpose. His arrangement did not have the web advance

 with an article attached to it through one stage of the operation, such as occurs in

 Sherman. Consequently he used a prepunched label supply wherein the prepunched

 area represents a relatively large portion of the web, which means that the

 web would not be strong enough to carry any article attached to it. Therefore

 in order to fulfil his concept the applicant developed a novel prepunched reel label

 supply to coact with his label applying apparatus.

 

 The Final Action also made reference to Canadian Patents Nos. 761,791 to

 Huffmann, and 728,557 to Sonenberger, which are of record in the prosecution

 of this application. Huffmann describes data card production from a supply

web of continuous length. This web moves rapidly through a punching and

 slitting machine using rotary-punch rolls. Sonberger relates to tabulating

 cards which are adapted to be processed through high speed printers. Fabric-

 ation of the card is from a pair of rolled webs which are unreeled and

 fastened to each other to form layers of the tabulating card. In our view

 neither of these references display a prepunched reel label supply as en-

 visaged by the applicant.

 

Affidavits testifying to the commercial success of the invention were sub-

 mitted by the applicant. They also purport to demonstrate that people skilled

 in this art consider the invention to be unobvious. In reviewing these

 affidavits we note that some of their statements relate to the labeling

 system of La Mers, and we do not doubt but that the inventive concept as

 a whole is patentable. It resulted in an important advance in the art,

 sufficient to justify the grant of a patent to the labelling apparatus. We

 observe that relevant jurisprudence indicates commercial success does not

 necessarily demonstrate the presence of invention, but it may raise some

 presumption of invention when a long-unsatisfied demand is met.

 

 At the hearing we were given two further affidavits providing evidence of

 some significance which was not available to the examiner when he made his

 rejection. In one, Mr. Thomas Keuper, a labelling expert, in addition to

 testifying to the commercial success of the LaMers invention, declares that

 the label supply itself is an important factor in permitting accurate place-

 ment of the labels on containers in high speed operations because of the way

 they are supported by the web remnants. He states: "Highly accurate label

 placement is insured by the label supply itself." Apparently rejections for

 faulty labelling were reduced substantially. Mr. Keuper points too to

 certain advantages in applying adhesive to this type of label. We quote:

 "Overall adhesive application has not proved successful in other elongated webs of

 indeterminate length, from which labels are required to be cut on the

 labeling device after adhesive application to the label, since the adhesive on

 the edge of the label area tends to seize the cutting die, and to form a

 "stringy" glue mess in the apparatus." This serves to distinguish this

 invention from Sherman's.

 

In his affidavit, Mr. Arthur R. Johnson, another expert, testifies that

the LaMers invention has improved the application of the adhesive, which

he attributes in part to the construction of the label web. He refers to

the fact that previously "it was always believed necessary to remove die-cut

labels from webs by cutting within the labeler, and it was not known that

labels could be removed in untorn condition without such cutting."

 

In assessing an invention it is important to avoid ex post facto analysis.

This has been stressed repeatedly, most recently by the Federal Court of

Canada in its decision of November 5, 1975, as yet unreported, in Pre-formed

Line Products and Slates Steel v. Payer and Co. In it we find:

 

As to the inventiveness, it is at times difficult to distinguish

between a true inventive step and a mere workshop improvement of

an invention. To constitute an invention, there must be a sub-

stantial step forward. On the other hand, great care must be taken

in examining an invention ex post facto to determine when there is

that element of inventiveness required, for a very great number of

extremely useful and truly ingenious inventions often appear to be

perfectly obvious and devoid of originality when examined after

they have been invented. Refer Appliance Service Co. Ltd. v. Sarco

Canada Ltd. (14 C. P. R. 2d, 59 at 69) , Farbwerke Hoechst AG.,

vormals Meister Lucius & Bruning v. Halocarbon (Ontario) Ltd. et al

(15 C.P.R. 2d, 105 at 124 & 125) where the authorities cited in

The King v. Uhlemann Optical Co., (1950 )Ex.C.R. 142 at 157 affirmed 1952

S.C.R. 143) are quoted.

 

The simplicity of a device is no proof that it was obvious and that

inventive ingenuity was not required to produce it and, if small

differences create large results, then the scintilla of inventiveness

required by law is in fact present. Refer O'Cedar of Canada Limited v.

Mallory Hardware Products Limited (1956 Ex. C.R. 299 at 317 and 318).

 

In this case we do not doubt but that from the art relied upon by the

examiner, there would have been little ingenuity in developing the label roll

claimed here once the new labelling system as a whole was known, and the need

for that roll appreciated. However the point is that the labelling system

was not known prior to the LaMers invention. The special label roll required

for the system is an integral part of the whole inventive concept, and

derives the necessary attribute of inventive ingenuity from that relationship.

To combine the applicant's own inventive concept with pieces of prior art to

hold the invention obvious is, we think, to practice the type of ex post facto

 analysis which has received the disapprobation of the courts. It is easy

after a discovery to say that it is obvious. In many cases the merit in an

invention lies in recognizing that a problem exists, and if the merit of a

case lies in the concept itself, it is not diminished by the fact that the

practical application of the idea, when once it is conceived, offers little

difficulty. Reliable Plastics v. Louis Marx et al, 17 F.P.C. 184 at 198.)

 

Having considered these matters and the advantages flowing from this invention,

we are satisfied that the Commissioner ought not to refuse a patent, and that

the claims define a patentable invention.

 

In the Final Action, the examiner objected to inclusion in the claims of appara-

tus limitations. We agree with him that the apparatus limitations appearing

in claim 1 at lines 3 to 10 are immaterial to what is being claimed. The claim

is for a label supply and in this instance we do not see how a recitation of

the parts of the apparatus in which it is used help define the label supply.

In fact we believe they run counter to the requirements of Section 36 of the

Patent Act by making less distant and explicit what is the invention to be

protected. We understand from Mr. O'Gorman's remarks at the hearing that he

had no objection to delete that portion of claim 1 reading: "said apparatus

including means for ..... printed, precut label supply" inclusive, and we

believe this should be done in the interest of clarifying the claim. The

title, too, which is that used in the patent, is inappropriate for what is

claimed in this application.

 

Another objection made by the examiner at the hearing was that the claims

contain features not in the disclosure as originally filed. He referred, for

example, to such terms as "bridges," "resiliency of plunger" and paper

"adapted for receiving adhesive." These terms were accepted, however, on

April 4, 1974, when they were submitted, and entered into the application. One

of the most significant in serving to distinguish this invention - resiliency

of plunger - does have support in the original disclosure at Figure S, and

the bottom of page 8 (formerly page 9). The latter states: "The front plate

99 is covered by a layer 105 of elastomeric material such as soft rubber." Considering

that the labels are to be applied to curved surfaces, and to glass bottles,

we think it reasonable to infer that those reading this disclosure when it

was filed would recognize that various types of resilient materials coull

be used.

 

The Board therefore recommends that the rejection for obviousness be with-

drawn. If the claims are amended as indicated above, the application should

be allowed to proceed.
