25 F.2d 180 | D. Mass. | 1922
This action is now before the court for hearing on bill, answer, and proofs, and is the same ease that was before the District Court in 270 F. 593, and on appeal before the Circuit Court of Appeals in 276 F. 478, and 281 F. 5. It is a suit in equily, charging infringement of reissued letters patent No. 14,049, applied for June 22, 1915, and issued January 11, 1916, to tho I. T. S. Rubber Company, assignee, through mesne assignments from John G. Tufford.
The invention is for an improvement in resilient heels, and particularly in cushion heels of the type comprising an elastic lift, adapted to be applied to the ordinary shoe heol. Claims 5, 6, 7, 8, and 9 are in issue, and the contention is that certain heels (similar to Exhibit 1, Series A, and Exhibit 2, Series B), which it is agreed were sold by the defendant in the district of Massachusetts between January 11,1916, the date of the letters patent, and the date when the complaint in the cause was filed, infringe these claims.
In addition to tho usual allegations in a bill for infringement, the plaintiff alleged that these same claims had been put in issue in two suits brought by it in the United States District Court for the Eastern District of Michigan, Southern Division, one against Walter Wendt & Co., and the other against Jones & Rosser, in which these parties were charged with infringement by sale of Essex Tite-Edge heels exactly like (except perhaps as to size and color) Exhibit No. 1, Series A; that the Essex Rubber Company assumed the entire charge of such suits, and controlled and maintained the same until entry of final decree, about November 1, 1920; that it participated in the suits and agreed with the defendants to, and did, pay all expenses thereof, including tho expenses and fees of defendants’ counsel and the costs and judgments; that, after the plaintiff was informed lhat the Essex Company had assumed entire control of the suits, interlocutory decrees pro eonfesso were entered, adj udging the patent valid and infringed, and thereafter the matters in each case were referred to a master for accounting; that proceedings were had before the master, at which counsel of the Essex Rubber Company appeared and presented the Essex Rubber Company’s interest; that thereafter, the plaintiff’s claims for damages and profits having been adjusted between the plaintiff and such counsel for the Essex Rubber Company, final decrees were entered (November 1, 1920) adjudging the patent valid and infringed by the sale of such Essex Tite-Edge heels, title in the plaintiff, and ordering the issuing of permanent injunctions, and that the plaintiff recover, in lien of profits, the amounts agreed upon. The plaintiff further charged that it was informed and believed in the exclusive control of the suits by the Essex Rubber Company, its participation therein, and its contribution thereto, before the entry of final decrees, as such actions were done openly by the Essex Rubber Company; and, in view of the foregoing allegations, it alleged that the Essex Rubber Company was estopped by the adjudication in the Wendt and Jones & Rosser Cases from contesting each and every issue in the case at bar, and in particular the question of infringement, so far as it related to the sale by tho Essex Rubber Company of heels like Exhibit 1, Series A.
The plaintiff also alleged in its hill that these same claims were put in issue in two suits brought by it in the United States District Court for the Northern District of Ohio, Eastern Division, one against H. H. Hackman & Co. and the other against Thomas Urbansky & Sons Company, in which H. H. Hackman & Co. were charged with infringement by sales of Essex Tite-Edge heels exactly like Exhibit No. 1, Series A, and Thomas Urbansky & Sons Company with infringement by sales of Essex Tite-Edge heels exactly like Exhibit No. 1, Series A, and Exhibit No. 2, Series B. It is further alleged that about November 8, 1919, the plaintiff procured a preliminary injunction in the Hack-man suit as to heel Exhibit 1, Series A; that about December 23, 1919, an interlocutory pro eonfesso decree was entered, and about August 7, 1920, a final decree; that the Essex Rubber Company contributed to the expenses of such suit paying all the expenses, and agreeing in advance with H. H. Hackman & Co. to pay all expenses of the suit, and that it paid all the court costs, and that all these acts were done to the knowledge of the plaintiff which was acquired before the entry of final decree.
As to the Urbansky suit, if, alleged that the Essex Rubber Company paid all the expenses of tho suit; that Urbansky took no steps therein without consulting the Essex Rubber Company, obtaining their direction with regard to said suit, and agreed with Urbansky to pay all expenses of such suit direetly after the suit was instituted; that about January 28, 1920, an interlocutory decree pro eonfesso was entered; that thereafter the matter was referred to a master for accounting; that proceedings were had before the master.
In view of the foregoing, the plaintiff alleged that the Essex Rubber Company was estopped, by the decree in the Hackman Case, to contest the issue of infringement in this case as to heels like Exhibit No-. 1, Series A, and by the decree in the Urbansky Case to contest that issue as to heels like Exhibit 1, Series A, and Exhibit 2, Series B.
In support of its allegations as to the Hackman matter, it appeared that Hackman & Co. were dealers in rubber heels, and had purchased heels from the Essex Rubber Company like those here in question. The plaintiff introduced a certified copy of the record in that suit, whieh comprised a bill of complaint charging infringement of the plaintiff’s patent by the sale of Essex Tite-Edge heels like Exhibit 1, Series A, a' motion for a preliminary injunction, a portion of a decree granting a preliminary injunction, a decree styled a final decree, but in fact being only an interlocutory decree pro iconfesso; as it referred the ease to a master to ascertain, state, and report to the court an account of the damages and profits due to infringing the plaintiff’s exclusive rights. The record does not show that Hackman & Co. appeared in the ease or filed an answer, or that any one else appeared and filed an answer, either in Hackman & Co.’s behalf or in behalf of .themselves; and, as the record fails to show that a final decree was entered, it necessarily follows that neither Hackman & Co. nor the defendant here is estopped by the interlocutory decree pro confesso. McGourkey v. Toledo & Ohio Ry., 146 U. S. 536, 545, 13 S. Ct. 170, 36 L. Ed. 1079; Smith v. Vulcan Iron Works, 165 U. S. 518, 524, 17 S. Ct. 407, 41 L. Ed. 810; Humiston v. Stainthorp, 2 Wall. 106, 17 L. Ed. 905; Australian Knitting Co. v. Gormly (C. C.) 138 F. 92, 100, and eases there cited. This renders it unnecessary to consider whether the Essex Rubber Company could, in any view, be regarded as a party to the cause and bound by a decree therein, if a final decree had been entered. But I find that the Essex Rubber Company did’not defend or control the suit; that, on being notified by Hackman & Co. of the bringing of the suit, it replied that it would not defend it, but would reimburse them, in ease they concluded not -to defend, for damages that might be recovered against them; and that Hackman & Co. replied that they had no intention of defending the suit.
As to the Urbansky matter, it appeared that Thomas Urbansky & Sons Company were also dealers in heels purchased from the Essex Rubber Company, and the plaintiff introduced a certified copy of the record in that ease, comprising a bill of complaint charging infringement of plaintiff’s patent by the sale of Essex Tite-Edge heels, a motion for preliminary injunction, an interlocutory decree pro confesso directing a reference to a master for an accounting, an order fixing the compensation of the master and stenographer, and directing that the same be taxed as costs, .and an order stating that, as a settlement had been made of all claims for profits, the reference to the master was withdrawn, the interlocutory decree made final, and the plaintiff was to pay all costs. There is nothing in the record that shows any one filed an appearance or answer in that ease for the defendant, or took any action in its behalf. The inference to be drawn from the record is that, after the ease was sent to the master, before whom it was necessary for the complainant (the present plaintiff) to adduce evidence showing what its damages were, the plaintiff procured an agreement with Thomas Urbansky & Sons Company as to the amount due it, obtained satisfaction thereof, and then had an order entered making the interlocutory decree pro confesso final, without having any sum adjudged due 'it as damages, but ordering that the costs incurred be paid by itself.
The deposition of Thomas J. Urbansky, vice president and secretary of the Urbansky Company, was introduced in evidence. In it he testified that, after the suit was brought against his company, he wrote to the Essex Rubber Company that they had been sued, and that the Essex Company replied, advising the Urbansky Company to let the matter go by default, and it would reimburse them for the expense they were put to; that, if this request had been contrary to their own interests, they would not have acquiesced in it; that neither the Essex Company nor any one representing them took any part in the conduct of the litigation; that all the Essex Company did was to reimburse them for what they paid out; that he personally arranged the settlement with Mr. Fales, attorney for the plaintiff; that Fales undertook to make him account for damages and profits from the sale of other types of heels in addition to the
The deposition of E. D. Fales, a member of the firm of Richey, Slough & Fales, counsel for the plaintiff in this suit, was introduced in evidence and related to the matter now under consideration. Mr. Fales had charge of the Hackman and Urbansky suits as counsel for the plaintiff, and, after taking the depositions of Mr. Urbansky and others in this suit, gave his own deposition. Fales testified that Urbansky told him that the Essex Company had agreed to reimburse his company,- and that his company was conducting the ease subject to the direction and suggestions of the Essex Company, and was doing nothing otherwise. But the correspondence introduced through these witnesses shows that Urbansky made the settlement with the plaintiff without any direction or suggestion from the Essex Company, and that all the Essex Company did was to reimburse him after it was notified of the settlement.
Taking into consideration all the evidence in the case, I find, as a fact, that the Urbansky Company of its own accord permitted the suit to go by default, and adjusted and settled the matter of accounting after the interlocutory decree pro confesso was entered ; that the final judgment made no award of damages, as they had been adjusted and settled by Urbansky out of court; and that • the Essex Company did not control the disposition of the case, either openly or otherwise. And I rule that the Essex Company is not estopped by the decree in the Urbansky Case to contest the question whether heels like Exhibit 1, Series A, and Exhibit 2, Series B, infringe the claims hero in issue.
In the suit against Wendt & Co., F. 0. Richey and E. D. Fales were the counsel, and Campbell, Bulkley & Ledyard were the solicitors for the plaintiff. The record in that case consists of a hill in equity charging the defendant with infringement of the claims here in issue by the sale of Essex Tite-Edge heels like Exhibit 1, Series A; the affidavit of John G. Tufford; the affidavit of Frank M. Slough; an order, entered May 3, 1920, to take tho bill pro confesso, no appearance having been entered on the part of the defendant, or answer or other pleading filed, although they should have been on or about the 26th day of April, 1920; a copy of an order filed April 1, 1920, directing Wendt & Co. to appear on the 19th of April, 1920, and show cause why an injunction should not issue as prayed for in tho bill; and an interlocutory decree pro confesso entered June 17,1920, appointing a commissioner to ascertain, take, and state an account, and adjudging that the plaintiff on such accounting should have the right to causo the examination of the defendant, his associates, clerks, servants, workmen, and other employees, and the production of books, vouchers, and documents of such defendant, and that such defendant attend before the master, and awarding a perpetual injunction and costs; a copy of the perpetual injunction filed June 24, 1920; a stipulation, filed November 1, 1920, signed September 13, 1920, by F. O. Richey and E. D. Fales, as counsel for the plaintiff, and Angelí & Turner, for the defendant, in whieh it was stipulated that the defendant would pay at once to the plaintiff $1,000 in cash, that the plaintiff would accept the $1,000 in lieu of profits and damages, and that no appeal should he taken from the final decree of the court in the case; a copy of a final decree entered November 1, 1920, reciting that the defendant, having made settlement of all claims of profits for the sum of $1,000, the reference to the master was withdrawn, that the plaintiff recover of the defendant the sum of $1,-000, and the order for an accounting be withdrawn. It further recited the matters set out in the interlocutory decree pro confesso as to validity and infringement.
The record in tho Jones & Rosser suit differs in no material respect from the facts shown in tho record in the Wendt suit. Both suits were begun at the same time; the patent relied on by the plaintiff in each was the same; the heels charged to be infringements weró the same; and the orders taking the bills pro confesso and the interlocutory decrees pro confesso were of the same character, and the respective dates at which they were entered up were the same. As to both matters it appears that Wendt on April 7, 1920,
Down to the time of the entry of the interlocutory decrees pro eonfesso and the issuing of the notices to the respective defendants to appear and account, I find that the Essex Company did not exercise control over the management and conduct of the suits; that the respective defendants allowed them to go by default of their own free will; and that the plaintiff had no reason to understand or believe that it was managing or conducting the cases.
Rule 16 in equity provides:
“It shall be the duty of the defendant, unless the time shall be enlarged, for cause shown, by a judge of the court, to file his answer or other defense to the bill in the clerk’s office within the time named in the subpoena as required by rule 12. In default thereof the plaintiff may, at his election, take an order as of course that the bill be taken pro eonfesso; and thereupon the cause shall be proceeded in ex parte.”
When the orders and interlocutory decrees pro eonfesso were entered, the cases thereupon, as required by the above rule, proceeded ex parte. Thereafter neither Wendt & Co., nor Jones & Rosser, nor any one else, had any right to appear, and never did appear, as a party in defense of either suit. Frow v. De La Vega, 15 Wall. 552, 554, 21 L. Ed. 60; Thomson v. Wooster, 114 U. S. 104, 119, 5 S. Ct. 788, 29 L. Ed. 105. And when Wendt & Co. and Jones & Rosser went before the master in response to his summons to account, they did so as witnesses in the plaintiff’s behalf, and in no other way. And the fact that the Essex Company co-operated with Wendt and Jones & Rosser through Angelí & Turner to bring about adjustments of the damages and profits, which adjustments were used by the plaintiff, in place of the master’s findings, as a basis upon which, in part, at least, to obtain the final decrees, does not seem to me to be such an exercise of control of the cases as would make the Essex Company a party defendant, even though the plaintiff understood that Angelí & Turner represented the Essex Company, as well as Wendt and Jones & Rosser, in adjusting the damages and profits.
Before the damages were adjusted, the issue of infringement upon which the plaintiff here relies had been decided by the court and embodied in the pro confesso decrees (Thomson v. Wooster, 114 U. S. 104, 113, 5 S. Ct. 788, 29 L. Ed. 105), and, although these decrees did not become binding as an estoppel until the entry of the final
Under the circumstances I find that the Essex Company did not control either the Wendt or Jones & Rosser suits, and rule that they are not estopped from contesting the question of infringement raised in this case.
The claims here in issue read as follows:
“5. A heel lift of substantially nonmetal-lie resilient material, having its body portion of concavo-convex form on every line of cross-section, the concave upper face lying entirely below a plane passing through the rear upper edge and the breast corners of the lift.
“6. A heel lift of substantially resilient material, having its body portion of concavoconvex form on every line of cross-section, the concave upper face lying entirely below a plane passing through the rear upper edge and the breast comers of the lift, said lift being provided with nail-receiving openings located near the center thereof.
“7. A heel lift of substantially resilient material, comprising a body portion, the attaching face of which is concave and the tread face of which is convex on every line of cross-section and normally held in such form by its • own inherent resiliency, the concave attaching face lying entirely below a plane passing through the rear upper edge and the breast corners of the lift, whereby to cause the cutiré margin of said lift to exert a uniform pressure on the heel of a shoo when said lift is positioned on the heel and the convex tread face thereof depressed to flatten said lift.
“8. A heel lift of resilient material, comprising a body portion of uniform thickness throughout its entire area and of concavoconvex form on every line of cross-section, the concave upper face of the lift lying entirely below a piano passing through the upper edge and the breast corners of said lift.
“9. A heel lift of resilient material, comprising a body portion, the attaching face of which is concave and the tread face of which is convex, the concave face of the lift being unbroken and lying entirely below a plane passing through the rear upper edge and the breast comers of the lift, whereby when the eonvex tread face is depressed to flatten said lift a suction will be created between the lift and the heel to hold the attaching face of the lift throughout its entire extent in contact with the exposed face of the heel.”
It will be seen that each of these claims, with the exception of claim 8, contains a clause wherein the concave upper face is described as “lying entirely below a plane passing through the rear upper edge and the breast comers of the lift,” and that in claim 8 the language of the claim is the same, with the exception that the word “rear,” before “upper edge,” is omitted. It appears, however, from an examination of the file wrapper of the reissued patent, that the omission of the word “rear” in the eighth claim was a clerical error, due to oversight; that counsel for the applicant and the Examiner in charge of the application understood that all these claims as drawn, at the time they were allowed, contained the word, “rear” preceding the words “upper edge.” This appears from what will be found in the file wrapper of the reissued patent, beginning on page 50 and extending to page 56. On page 54 of the file wrapper the Examiner says: “In each of the claims 5, 6, 7, 8, and 9 applicant specifies 'that the concave upper face lies entirely below a plane tangent to the rear upper edge and the breast corners of the lift,’ ” and it there appears that these claims were rejected, not because of the wording of the claims, but because of one of the drawings (Fig. 2) filed in the case. This drawing (Fig. 2) did not at that time conform to the shape of the plaintiffs heel, and, because Of that, the claims were disallowed, as they would not read upon Fig. 2. The only change thereafter made in the claims as they then stood was the insertion of the words “passing through” for “tangent to” in the clause here in question, and to define the meaning of the clause as amended. Figure 2 having been changed to conform to the plaintiff’s heel, the following provision was inserted in the specification:
“By references to Figs. 2 and 4 of the drawing's, it will be seen that the concave upper face of the lift lies entirely below a plane passing through the rear upper edge and breast corners of the lift whereby to
This amendment,-in connection with new Figure 2, clearly shows that the plaintiff’s heel was to have a rear upper edge and breast corners located “above the upper side edges and the breast edges of the lift,” and that the words “passing through” meant a plane passing through the rear upper edge and breast comers, and above the side and breast edges.
The conclusion that the word “rear” was omitted from the clause under consideration in claim 8 through inadvertence, and was a clerical error, is further shown by the language used in the claim itself; for a plane passing through the upper edge, if upper edge meant the entire upper edge, as in defendant’s heel, would pass through the breast corners as well, and there would have been no occasion for stating in that clause thát it passed through the breast comers. Then, again, down to the time it was pointed out in the decision of the Circuit Court of Appeals of June 7, 1922 (281 F. 5), the plaintiff had always recognized that this clause in claim 8 read the same as it does in the other claims; that was its position before the District Court, before the case was taken to the Circuit Court of Appeals, and has apparently been its position before other courts where these elaims have been considered.
The defendant makes and sells two sets of heels, which the plaintiff claims infringe its patent — Exhibit No. 1, Series A, and Exhibit No. 2, Series B. Exhibit No. 1, Series A, is a concavo-convex heel on every line of cross-section, the concave face of which, however, is located below a plane which passes through the entire upper edge of the lift, except the breast edge. The breast edge is raised considerably above the lowest point back of it in its concave face, but not enough to be in the same plane with the side and rear upper edges of the heel. Exhibit No. 2, Series B, differs from Exhibit No. 1, Series' A, only in the fact that the breast edge at its lowest point is about one-fiftieth of an inch higher than the lowest point back of it in the concave face of the lift.
In the decision handed down by the Circuit Court of Appeals in this ease on June 7, 1922 (281 F. 5), it was held that the heel described by the language of claims 5, 6, 7, and 9 was, “the three-point contact form, having its side and breast edges, as well as its concave attaching face, located below a plane passing through the rear upper edge and breast comers of the concave face,” and that this was due to the fact that the claims contained the clause defining the concave upper face as “lying entirely below a plane passing through the rear upper edge and breast comers of the lift.” And as I find that claim 8 embodies the same clause, the word “rear”-having been omitted through oversight, that claim, as well as claims 5, 6, 7, and 9, describes a heel of “the three-point contact form, having its side and breast edges, as well as its concave attaching face, located below a plane passing through the rear upper edge and breast corners of the concave face.” So far as this clause of the elaims is concerned, they stand alike upon the question of infringement.
- It is the contention of the defendant that these elaims are not entitled to a broad construction; that the patentee, by acquiescing in the denial of elaims asked for in the Patent Office and by the acceptance of elaims embodying the clause, “the concave upper face lying entirely below a plane passing through the rear upper edge and breast comers of the lift,” limited himself in such a way that he is not entitled to a broad range of equivalents, and that, when the claims are so limited, the defendant’s.heels do not infringe.
In the original application, by amendments filed December 15,1913, and April 21, 1914, the applicant asked for claims reading as follows:
“A cushion heel lift having a concave attaching face and a convex tread face, the edges of the attaching face all occupying the same plane.
“A cushion heel lift having a concave attaching face and a convex tread face and having its edges radial to the curvature of said faces, the edges of the attaching face all occupying the same plane.”
These claims, July 7, 1914, were rejected by the Examiner, the rejection was acquiesced in by the applicant, and the original patent was issued with claims 1, 2, 3, and 4 only. The claims here in controversy were granted on the application of June 22, 1915, of the reissued patent. In that application six new claims were asked for, all of which, on July 8, 1915, were rejected. These claims read as follows:
“5. A cushion heel lift having a concave-convex form on every line of cross-section.
“6. A cushion heel lift, the attaching face*187 of which, is concave, and tho tread face of which is convex on every line of cross-section.
“7. A cushion heel lift, the attaching face of which is concave and tho tread face of which is convex on every line of cross-seetion, there being nail-receiving openings penetrating the lift near the center thereof.
“8. A cushion heel lift, the attaching face of which is normally concave, and the tread face of which is normally convex on every line of cross-section, thereby to cause the entire margin of the lift to snugly engage the heel of a shoe when said lift is positioned on the heel and pressure applied to the convex face thereof to flatten said lift.
“9. A cushion heel lift having a concavoconvex form on every line of cross-section, and provided with openings piercing the lift near the crest of the convex face thereof.
“10. A heel lift, formed of yieldable material and provided with a normally convex tread face and a normally concave attaching face defining a suction area whereby, when the lift is positioned on the flat surface of a heel and pressure is applied to the convex face of the Lift, the margin of said lift will be retained in engagement with the margin of the heel by the action of tho suction area.”
Those claims having been rejected by tho Examiner, the applicant, on August 20,1915, asked that they be reconsidered and filed an additional claim No. 11. August 30, 1915, the applicant acquiesced in the rejection of claims 5 and 6, suggested slight amendments to the others, and added two claims, requesting that claim 7 be numbered 5, and so on, down to 11. October 2, 1915, the Examiner rejected these claims, and on October 13, 1915, the applicant acquiesced in the rejection, and requested the substitution of four new claims, 5, 6, 7, and 8. These last claims read as follows:
“5. A heel lift of resilient material, comprising a body portion of concavo-convex form on every line of cross-section, and normally held in such form by its own inherent-resiliency.
“6. A heel lift of resilient material, comprising a body portion, the attaching face of which is concave and the tread face of which is convex on every lino of cross-section, and normally held in such fo-rm by its inherent resiliency only, said lift being provided with nail-receiving openings located near the center thereof.
“7. A heel lift of resilient material, comprising a body portion, the attaching face of which is concave and the tread face of which is convex on every line of cross-section, and normally held in such form by its inherent resiliency only, whereby to cause the entire margin of the lift to exert a uniform, pressure on the heel of a shoe when said lift is positioned on the heel and the convex tread face thereof depressed to flatten said lift.
“8. A heel lift of resilient material, comprising a body portion, tho attaching face of which is concave and the tread face of which is convex, and normally held in such form,by its inherent resiliency only, the concave face of the lift being free from projections, whereby, when the convex tread face is depressed to flatten said lift, a suction will he created between the lift and the heel to hold the attaching face of the lift through its entire extent in contact with the exposed face of tho heel.”
In the remarks of applicant’s counsel ip. presenting these new claims it was stated “the foregoing amendment has been made after a personal interview with the Principal Examiner, during which a specimen heel lift, constructed in accordance with applicant’s invention and also exhibit rubber heels now on the market, were presented for inspection.”
October 22, 1915, the Examiner, replying to the amendment filed October 13, 1915, rejected the claims and stated, “Applicant may regard this rejection as final, if he so desires,” which meant that he might take an appeal, if ho wished.
October 27,1915, the applicant acquiesced in the rejection of these four claims, and offered an amendment to his specification reading as follows:
“By* reference to Pigs. 2 and 4 of the drawings, it will be seen that the concave upper face of the lift lies entirely below a plane tangent to the rear upper edge and the breast corners of the lift, whereby to cause the entire margin of said lift to exert a uniform pressure on the heel of a shoe when the lift is positioned on the heel and the convex face thereof depressed to flatten said lift.”
He also offered five new claims — containing the clause “the concave face lying entirely below a plane,” etc. — which read the same as claims 5, 6, 7, 8, and 9 of the reissued patent, except that, where the words “passing through” are used in the claims in suit, the words “tangent to” appeared. Prom the remarks of counsel in presenting these amendments it appears that he relied largely, to differentiate these claims from the prior art, on the fact that the concave upper face of the lift lay entirely below a plane tangent to the rear upper edge and breast comers of the lift.
On November 16, 1915, the Examiner, in
On November 24, 1915, the applicant presented a new sketch of Figure 2, showing the breast and side edges of the heel slightly curved, so that it presented a correct sectional view of Fig. 4, and asked to amend the clause added to the specification by the amendment of October 27, 1915, so that it should read as follows:
“By references to Figures 2 and 4 of the drawings, it will be seen that the concave upper face of the lift lies entirely below a plane passing through the rear upper edge and breast comers of the lift, whereby to cause the entire margin of said lift to exert a uniform pressure on the heel of a shoe when the lift is positioned on the heel and the convex face thereof depressed to flatten said lift. In other words, owing to the curvature of the concave attaching face' of the lift, the rear upper edge and breast corners of said concave attaching face are disposed in a plane above the upper side edges and the breast edges of the lift.”
And to meet the change in the specification from “tangent to” to “passing through,” he requested that the words “tangent to” in his five new claims of October 27, 1915, be changed to “passing through,” and asked that an additional claim, which.is claim 10 of the patent, be allowed.
It is apparent, from the matters referred to as having taken place during the course of proceedings in the Patent Office, that the patentee sought broad elaims, but was denied them, and acquiesced in the denial.
In the original patent he sought claims for a concavo-convex heel, having a straight upper edge, but was denied them. .
In the reissued patent he first sought claims fór “a heel lift having a concavoconvex form on every line of cross-section” —very broad elaims, and in no wise limited as to character or location of the edges of the attaching face of the heel. He was denied these. He then asked for elaims somewhat more limited, calling for “a lift of resilient material, comprising a body portion of concavo-convex form on every line of cross-section and normally held in such form by its own inherent resiliency,” but so far as the character and location of the edges of the-attaching face were concerned equally as broad as the first asked for. These claims were denied, and he acquiesced. Finally, on. October 13, 1915, he submitted five claims,, substantially like those previously submitted,, but. all containing the clause “the concave upper face lying entirely below a plane passing through the rear upper edge and the breast comers of the lift,” or its equivalent, which defined the character and location of the edges of the attaching face.
Such being the ease, it necessarily follows that claims which were allowed with the qualifying clause cannot be construed broadly, and to cover what would be embraced within the claims as they stood June 22, 1915, or October 13, 1915; for to do so would render the qualifying clause meaning.less and give to the present claims an interpretation such as the plaintiff would only have been entitled to, had the earlier claims of June 22 and October 13, 1915, not been rejected. The patentee, having narrowed his elaims by the insertion of the restricting clause, in order to obtain any claims under the reissued patent, cannot, by construction or by resorting to the doctrine of equivalents, give the elaims the larger scope which they might have had without the restricting clause. Webber Electric Co. v. Freeman Electric Co., 256 U. S. 668, 677, 41 S. Ct. 600, 65 L. Ed. 1162. Having acquiesced in the rejection of
It has been argued before me that claims 5, 6, 7, 8, and 9 of the patent cannot he differentiated from claim 10, if the restricting clause of these claims is given the same meaning as the restricting clause in claim 10, and which the specification says means the same. I do not think this is so. Claim 5 is differentiated from all the other claims, in that it requires the heel lift to be of “substantially nonmetallie resilient material.” Claim 6 is differentiated by the heel being provided with “nail-receiving openings located near the center thereof”; claim 7, by the fact that the heel is “normally held in such form by its own inherent resiliency”; claim 8, by the body portion of the heel being of “uniform thickness throughout its entire area”; claim 9, by “the concave face of the lift being unbroken.” Claim 10 is differentiated from claim 5 by the clause “substantially resilient material” which is not necessarily nonmetallie as in claim 5; from claim 6 by not having nail-receiving openings; from claim 7 by not being held in shape by its own inherent resiliency; from claim 8 by not being of uniform thickness throughout its entire area; and from claim 9 by not having its face limited to an unbroken concave face. Claims 5, 6, and 8 in express terms provide that the body portion of the heel shall be “of concavo-convex form on every line of cross-section”; claims 7 and 10, that the attaching face of the heel shall be “concave and the tread face convex on every line of cross-section.” Claim 7 also contains a whereby elauso, which states in substance that the elements of the claim are such as to cause the entire margin of the lift to exert a uniform pressure on the shoe heel when said lift is positioned on the heel, and the evidence shows that this uniform pressure .can be obtained only in case the breast edge is raised, as well as the side and rear edges. This being so, it follows that the elements described in claim 7 call for a heel the concave face of which is concave on every line of cross-section. And what is true of claim 7 is true of claim 10. Claim 9 does not use the term “on every line of cross-section,” either as to the concave face or the convex tread, hut contains a whereby clause, in which it states that, “when the convex tread face is depressed to flatten said lift, a suction will be created between the lift and the heel to hold the attaching face of the lift throughout its entire extent in contact with the exposed face of the heel.” .While the language of this whereby clause is not the same as the whereby clause in claim 7, it means the same, and the evidence shows that the result here claimed can be produced only in case the breast is raised as well as the side and rear edges of the heel. Furthermore, if claims 7, 9, andlO are not capable of this construction, they would seem to be invalid, as calling for a heel not disclosed in the specification.
As said by the Circuit Court of Appeals in this case, “the fundamental conception of plaintiff’s patent as to form is one ‘molded or cut so as to be of a concavo-convex form on any line of cross-section,’ and its principal object or function when so formed is (according to the language of the specification) ‘that, when the lift is subjected to pressure, any tendency for the edge portions of the lift to crowd beyond the sides of the shoe heel will be counteracted, and there will be equally as great a tendency for the material of the lift to crowd or compress toward the center thereof.’ This means that the retroactive force inherent in the rubber will counteract any tendency of the edge portions of the lift to crowd beyond the sides of the shoe heel when the lift of the patent is subjected to pressure, and thus keep the side and breast edges of the lift in alignment with the side and breast edges of the shoo heel and in close contact therewith.”
It is conceded by the defendant that, if the plaintiff’s claims are not restricted by the clause here under consideration, and are entitled to a construction warranting a wide range of equivalents, it infringes; but I rule that the claims are restricted by the provision which they all contain, that plaintiff is not entitled to a broad construction of its claims, and find that heels like Exhibit 1, Series A, and Exhibit 2, Series B, do not infringe the plaintiffs claims.
A decree will be prepared, dismissing the plaintiffs bill.
