“1. We agree not to terminate the above described agreement at the end of the contract year ending September 31, 1942. However, it is mutually agreed that our right to terminate said agreement as set forth in paragraph 5 thereof shall otherwise remain in full force and effect.
“2. Effective September 1, 1942, and for the duration of the present war involving this Country and Germany, Japan and/or Italy, it is mutually agreed that paragraph 16 of said agreement shall be amended so as to read as follows:
“ ‘The Licensee guarantees to the Licensor that the total amount to be paid to the Licensor in or in lieu of all royalties under this agreement including, but without limitation, paragraphs 4(b), 4(c) and 11 in respect of sales and rentals made during each year of the third and each succeeding year of this contract shall be at least Twenty-Four Hundred Dollars ($2400.).

In the event that such royalties due on sales and rentals made during the year in question do not equal $2400. during such year, the Licensee shall reimburse itself out of royalties next subsequently due in respect to payments on sales and rentals made during the year in question. In the event that the aggregate royalties due on such sales and rentals made in the year in question up to the last day of any month in the year in question exceeds the aggregate monthly guarantees, only royalties due shall thereafter be paid until they in the aggregate fall below the aggregate monthly guarantees. In the event that the aggregate monthly guarantees up to the last day of any month in the year in question exceeds the aggregate royalties due, only the monthly guarantees shall thereafter be paid until they in the aggregate fall below the aggregate royalties due. The Licensee does not guarantee any amount of operations or volume of sales or rentals. The above guarantee shall be upon or in lieu of royalties on sales and rentals made during each year without relation to sales and rental in any other year.’
“Upon termination of the war with said countries said paragraph 16 shall revert to its form existing immediately before the execution of this amendment.
“3. Except as expressly amended in this letter, all of the terms, covenants, conditions and provisions of said agreement, dated as of September 1, 1933, amended as above set forth, shall remain in full force and effect.
“If the above meets with your approval, will you please sign the acceptance below and on the enclosed duplicate and return one original signed letter to us, whereupon the above will become binding.
“Very truly yours,
General Printing Ink Corporation

12. Following the execution of the aforesaid Declaration of Trust, the defendant continued to render monthly *809statements to plaintiff purporting to cover all sales affected and paid royalties shown due thereunder until on or about February 26, 1952.
13. The only patents licensed by the Agreement, or amendments thereto, which had not expired prior to February 26, 1952, are identified as follows:
Country Reg. No. Ser. No. Issue Date Expiration Date
U. S. 1,992,621 458,789 Feb. 26, 1935 Feb. 26, 1952
U. S. 2,000,520 356,326 May 7, 1935 May 7, 1952
Canada 356,880 419,343 March 31, 1936 March 31, 1954
14. The photo-composing machines and apparatus manufactured and sold or rented by the defendant after February 26, 1952, were not covered by U. S. Patent No. 2,000,520.
15. The disclosures in U. S. Patent No. 1,992,621 and Canadian Patent No. 356,880 were the same and involved photo-composing machines.
16. Between February 26, 1952, and March 31, 1954, the defendant paid to plaintiff royalties on its Canadian sales or rentals of photo-composing machines or apparatus or paid to defendant $200 per month as a minimum royalty as shown in the following schedule:
Month Year Amount
March 1952 $ 3.52
April 1952 1.10
May 1952 26.56
June 1952 35.54
July 1952 1.70
August 1952 3.95
Sept, through Dec. 1952 200.00 per month
Jan. through Dec. 1953 200.00 per month
Dec. through March 1954 200.00 per month
17. Except for an adjustment to correct errors in the Canadian royalties, defendant did not account for or make payments on account of the minimum guarantee or royalties on any sales or rentals of photo-composing machines or apparatus during said period other than those above listed.
18. By letter dated February 12, 1952, defendant advised plaintiff that the aforesaid Agreement would cease when U. S. Patent No. 1,992,621 expired on February 26, 1952, as the said patent was the only one under which the defendant was then manufacturing and selling. Subsequently this position was changed to admit an obligation for payment of royalties on Canadian sales only, or a $200 per month minimum.
19. Defendant admits that proper and timely objections were made on plaintiff’s behalf to defendant’s position with respect to its obligation to pay royalties under the Agreement, as amended after February 26,1952.
II. Conclusions of Law
1. The matter is properly before the Court.
2. The minimum annual royalties due under the Agreement, as amended, for all years in question was $6,000, payable $500 per month, as the War referred to between United States and Germany, *810Japan and/or Italy had terminated within the meaning of the Amendment dated May 28, 1942, prior to September 1, 1951.
3. Under the Agreement dated September 1, 1933, as amended, defendant was and is obligated to pay royalties on the sale and/or rental by defendant of all photo-composing machines and apparatus as defined in said Agreement, as amended, or to make payments under the minimum royalty provision thereof at the above-mentioned monthly rate, whichever is applicable, until the expiration of March 31, 1954, of the last patent covered by said Agreement.
4. Plaintiff is further entitled to interest on all balances that may be found due from the dates they respectively became due until payment, and costs in this suit.
