      Robert F. Cunningham, for the respondent.
    
      
       The cases of the following petitioners are consolidated herewith: Zenith Dredge Co., docket No. 3998-68; Lloyd K. Johnson and Marion Johnson, docket No. 3999-68; and Morris J. Opsahl and Eileen D. Opsahl, docket No. 4000-68.
    
   DawsoN, Judge:

In these consolidated cases respondent determined the following Federal income tax deficiencies:

Pursuant to leave granted at the trial, respondent claims the following increased deficiencies:

The first issue for decision is whether transfers by petitioners of all their rights in certain patents constituted' a sale of either capital assets held for more than 6 months or of section 1231 assets, the gain from which is taxable to petitioners as long-term capital gain, or whether the transfers were something less than a sale, thus causing the gain to be taxable as ordinary income. A second question, raised alternatively by respondent as an affirmative issue, is whether the petitioners realized immediate gain in 1961 upon their respective sales of the patents, such gain being measured by the fair market value as of the date of sale of petitioners’ rights to receive' future payments under the sales contract, less their bases in the patents, or whether such gain is realized as payments are actually received by the petitioners.

FINDINGS OF FACT

Some of the facts have been stipulated by the parties. The stipulation of facts and exhibits attached thereto are incorporated herein by this reference.

Donald C. MacDonald (hereinafter called MacDonald) and Maud G. MacDonald are husband and wife who at the time of filing their petition herein resided in Duluth, Minn. They filed timely joint Federal income tax returns for 1961, 1962, 1963, 1964, and 1965 with the district director of internal revenue at St. Paul, Minn. They reported their income on the cash receipts and disbursements method of accounting.

Zenith Dredge Co. (hereinafter called Zenith) is a corporation organized in 1905 under the laws of the State of Minnesota which during the taxable periods here involved and at the time of filing its petition herein maintained its principal office at Duluth, Minn. Zenith’s Federal corporation income tax returns for the calendar years 1961,1962, and 1963, the period January 1, 1964, to April 30,1964, and the fiscal year ended April 30, 1965, were timely filed with the district director of internal revenue at St. Paul, Minn. Zenith kept its 'books and reported its income on the accrual method of accounting. However, Zenith reported for income tax purposes the royalties received under the “Sub-License” dated May 12, 1949, and the payments received under the “Agreement of Sale” dated October 6,1961, when actually received and not when accrued during and prior to the taxable years here involved.

Lloyd K. Johnson (hereinafter called Johnson) and Marion Johnson are husband and wife who at the time they filed their petition herein resided in Duluth, Minn. They filed timely j oint Federal income tax returns for 1961, 1963, 1964, and 1965 with the district director of internal revenue at St. Paul, Minn. They reported their income on the cash receipts and disbursements method.

Morris J. Opsahl (hereinafter called Opsahl) and Eileen D. Opsahl are husband and wife who at the time they filed their petition herein resided in Duluth, Minn. They filed timely joint Federal income tax returns for 1961, 1962, 1963, and 1964 with the district director of internal revenue at St. Paul, Minn. They reported their income on the cash receipts and disbursements method.

At all times material here, Zenith had 3,000 shares of voting common stock issued and outstanding, of which 30 shares were owned by Johnson, 30 shares were owned by Opsahl, 617 shares were owned by or for the benefit of MacDonald, and 700 shares were owned by trusts for the benefit of MacDonald’s children, 266 shares were owned by or for the benefit of MacDonald’s sister, 438 shares were owned by cousins of MacDonald, and the balance of 919 shares was owned by approximately 30 stockholders all unrelated to MacDonald, Johnson, or Opsahl.

Superior Wood Products, Inc., is a corporation organized under the laws of the State of Minnesota in 1945, with its principal office located in Duluth, Minn. At all times material here, its outstanding voting common stock was owned directly or indirectly one-fourth (:%) each by Johnson, Opsahl, MacDonald, and Zenith. In 1954 by an amendment to its charter, Superior Wood Products, Inc., changed its name to Superwood Corp. (hereinafter called Superwood).

Duluth-Superior Lumber Co. (hereinafter called Duluth-Superior) was a corporation organized in 1946 under the laws of the State of Minnesota, with its principal office in Duluth, Minn. At all times material here, the voting common stock and the nonvoting common stock of Duluth-Superior were owned one-fourth (*4) each by Johnson, Opsahl, MacDonald, and Zenith.

Chapman Forest Utilization, Inc. (hereinafter called C.F.U.), was a corporation organized under the laws of the State of Oregon, with its principal office in Corvallis, Oreg. The principal stockholder of C.F.U. was Ealph Chapman (hereinafter called Chapman), an individual residing in Corvallis, Oreg. None of the petitioners at any time owned any stock or other interest in C.F.U.

Sometime prior to August 11, 1947, Chapman developed and invented certain methods whereby wood or wood waste could be manufactured into a product known as hardboard. He also had developed and invented certain special machinery, equipment, and processes necessary and useful in the manufacture of hardboard. Hardboard itself was not a new product, but the Chapman process offered an inexpensive means of producing it.

On or about August 11, 1947, Chapman entered into an agreement with Canadian Forest Products, Ltd., of Vancouver, British Columbia, whereby Chapman gave Canadian Forest Products a license to use the Chapman process in the province of British Columbia for the manufacture of hardboard of a specific gravity above .8. The license was “exclusive,” except that Chapman reserved the right, after 2 years, to make the patents and processes available to a specified British Columbia company on terms “not more favourable.” Eoyalties were dependent on production. The license was for a term of 10 years, except that Canadian Forest Products could terminate on 60 days’ notice by paying liquidated damages of $50,000. At the end of the 10-year term, Canadian Forest Products could use the process without charge, on a nonexclusive basis, for the remaining life of the patents. By an agreement dated February 25,1948, the royalty schedule was corrected and amended by the parties. No payments have been made under this agreement since 1958.

Subsequent to the Canadian agreement and prior to October 18,1947, Chapman assigned to C.F.U. his entire right, title, and interest in and to any inventions and any letters patent which might issue with respect to the Chapman process. C.F.U., as assignee, acquired the following United States letters patent (hereinafter called Chapman United States patents) and Dominion of Canada letters patent (hereinafter called Cbapman Canadian patents) embodying the inventions employed in the so-called Chapman process (hereinafter collectively called Chapman patents):

Prior to October 18, 1947, C.F.U. granted a royalty-free license to Chapman Manufacturing Co., a partnership, to manufacture hardboard in Corvallis, Oreg., and to sell the product anywhere.

On October 18, 1947, C.F.U. and Duluth-Superior entered into an agreement whereby C.F.U. would provide plans and supervision to help Duluth-Superior adapt a manufacturing plant to the Chapman process, and would train personnel to operate the plant. The agreement further provided:

4. For a period of two years from the date, Chapman agrees not to enter into any agreement with third parties for the establishing of a plant or plants for the production of “Hardboard” of a specific gravity above .8 in the following states: North Dakota, South Dakota, Nebraska, Minnesota, Iowa, Wisconsin, Illinois, Michigan and Indiana. At any time two years after production has commenced at the first plant, Chapman may enter into such agreement or agreements provided six months’ notice is first given Corporation of intention to enter into such agreement or agreements. If Corporation, within the said six months’ period, enters into an agreement with Chapman for the establishing of such plant or plants, then Chapman agrees not to contract with third parties for the establishing of such plant or plants. Provided, however, that when Corporation shall have established the following capacity in the following states to wit:
North Dakota. 40 M per day
South Dakota. 40 M do do
Nebraska _ 40 M do do
Minnesota _ 100 M do do
Iowa _ 40 M do do
Wisconsin 100 M do do
Illinois _ 40 M do do
Michigan _ 100 M do do
Indiana_ 40 M do do
Then and in that event, the right of the Corporation to said process, etc., shall become exclusive as to that state. PROVIDED, however, that any excess in one state can be used in computing the amount required in an adjoining state for said exclusive right.
5. That in the event Chapman obtains letter patent on any of the present type of process or machinery required or suitable for the manufacture of “Hardboard,” a license is hereby automatically extended for the use of such process or machinery by the Corporation to manufacture in North Dakota, South Dakota, Nebraska, Minnesota, Iowa, Wisconsin, Illinois, Michigan and Indiana, and, sell anywhere in the world, subject to the conditions hereinafter named, such “Hardboard.” PROVIDED, however, that said license to manufacture shall be nonexclusive except as above set forth and non-assignable, and will be for the term of the patents.

The payments made by Superwood and Little Nock Hardboard, Inc., to Opsahl, MacDonald, Johnson, and Zenith, as provided for under the terms of paragraph 2 of the sublicense dated May 12,1949, as amended, for the years 1950 to October 6, 1961, inclusive, and as provided for under the terms of paragraph 2 of the agreement of sale dated October 6,1961, for the period October 6,1961, to June 15,1970, inclusive, are as follows:

Opsahl, Johnson, MacDonald, and Zenith each received royalties from Snperwood under the sublicense dated May 12, 1949, as amended, during the period from January 31,1961, through October 6,1961, in the total amount of $63,'394.69.

In their respective 1961 Federal income tax returns, the petitioners each reported the royalties received from Superwood during the period January 31,1961, to October 6,1961, as follows:

Boyalties received Amortization of patents Ordinary income
$63, 394. 69 $3, 935. 34 $59, 459. 35

The amount reported by each petitioner as the amortization of their respective bases in the Chapman patents of $62,500 was computed on the straight-line method by using the expiration date of the last of the Chapman patents to expire (December 7,1971) as the terminal date of the useful life of the patents over the period from January 31, 1961, to October 6, 1961. The unamortized basis in the patents in the hands of each of the petitioners as of October 6, 1961, was $58,564.66.

In their respective 1961 Federal income tax returns, petitioners each reported the transaction involved in the agreement of sale dated October 6,1961, as the sale of a capital asset (the Chapman patents) held for more than 6 months, and specifically elected to report the gain from the sale on the installment method, as follows:

Payments received Amortization of patents Long-term capital gain
$11, 983. 56 $863. 83 $11, 119. 73

The amount reported by each petitioner as the amortization of their respective bases in the patents of $58,564.66 was computed by using the expiration date of the last of the Chapman patents to expire (December 7,1971) as the terminal date of the useful life of the patents over the period from October 6, 1961, to December 31, 1961. Despondent allowed each petitioner to amortize his respective bases in the patents over the period October 6,1961, to May 31, 1970 (the last date under the agreement of sale for which payments would accrue).

During the taxable years involved herein the petitioners received the following payments from Superwood under the agreement of sale dated October 6,1961:

The amortization of each petitioner’s basis in the Chapman patents as allowed in the notice of deficiency with respect to the payments received from Superwood under the agreement of sale dated October 6, 1961, during the taxable years involved herein as follows:

Neither Superwood nor Little Nock Hardboard, Inc., has produced any hardboard in Canada and petitioners have not received any payments under the agreement of sale dated October 6,1961, by reason of any production covered by the Chapman Canadian patents.

As stated above, prior to May 5, 1949, C.F.U. had entered into a contract with Chapman Manufacturing Co., a partnership consisting of Ralph Chapman and others, which contract was referred to in the agreement dated May 5, 1949, and which contract licensed Chapman Manufacturing Co. to manufacture hardboard at its plant located in Corvallis, Oreg., and to sell hardboard anywhere in the world, royalty-free of present or future patents obtained by C.F.TJ. or Chapman.

On June 14,1951, the plant located at Corvallis, Oreg., was purchased by certain persons (hereinafter called John D. Nelson, et al.). On June 14, 1951, C.F.U. and Chapman granted a “License” dated June 14, 1951, to John D. Nelson, et ah, which provided as follows:

Whereas, the persons listed on “B” attached hereto are purchasing the real property described on “A” attached hereto together with the plant and equipment thereon which are used to manufacture “hardboard” under the Chapman process (“hardboard” being board of a density of .8 or greater), and as a part of the consideration therefor, and for a consideration of the sum of $1.00 cash in hand paid to the undersigned Chapman Forest Utilization, Inc., and Ralph Chapman personally, the following agreement is made;
Now Thebefobe, in consideration of the purchase of the real property described in “A” attached hereto, and by reference made a part hereof, and in further consideration of the sum of $1.00 cash in hand paid to the undersigned, receipt whereof is hereby acknowledged, the undersigned and each of them, hereby perpetually and irrevocably license and empower the purchasers of said real property whose names appear on “B” attached hereto and by reference made a part hereof, and their successors in interest to said real property, to manufacture on the said real property, and to sell anywhere in the world, “hardboard” as herein defined under the Chapman process, it being the intention hereby to license and empower the said named persons, and those who succeed to ownership and/or lawful occupancy of the said premises, to manufacture “hardboard” royalty free of present or future patents obtained by the undersigned, or either of them.
This license may not be assigned in whole or in parlt separate and apart from the lawful ownership or occupation of the said real property.

The license superseded and replaced the prior contract between C.F.TJ- and Chapman Manufacturing Co. The real property described in the license is the property upon which the plant at Corvallis, Oreg., is located. The real estate and the license were subsequently assigned by John D. Nelson, et al., to Chapman Manufacturing Co., Inc., a Washington corporation (hereinafter called Manufacturing, Inc.). On March 14,1956, Manufacturing, Inc., assigned the license to Chapman Manufacturing Co., an Oregon corporation (hereinafter called Manufacturing Co.).

On July 81, 1958, Evans Products Co., a Delaware corporation (hereinafter called Evans Products), acquired the real property upon which the plant at Corvallis, Oreg., is located, and the license dated June 14,1951, by assignment from its wholly owned subsidiary Manufacturing Co. The license was in existence on January 31, .1961, and on October 6, 1961, and during all the taxable years involved herein. On or about November 1965, Evans Products abandoned the use of the process covered by said license.

None of the petitioners had any stock or other interest in Manufacturing, Inc., in Manufacturing Co., in John D. Nelson, et al., or in Evans Products.

At all times during the years involved herein, and for many years prior thereto, MacDonald has been an officer of Zenith, and he has not been engaged in any other significant trade or business. At all times during the years involved herein, and for many years prior thereto, Opsahl has been an officer of Superwood, and he has not been engaged in any other trade or business. At all times during the years involved herein, Johnson has been a lawyer engaged in the practice of law, and he and his wife have been engaged in various other trades or businesses including the Ameriply Veneer Co., the High Falls Gift Shop, the Trading Post Gift Shop, Arrow-Head Plastics, iron ore and other mineral exploration and development, and timber sales. At all times during the years involved herein, Zenith has been principally engaged in the businesses of dredging, pile driving and dock construction, and related activities. MacDonald, Opsahl, Johnson, and Zenith have never had any interests in any patents, patent applications, or inventions other than those described herein except that (1) Johnson acquired in about 1959 an interest in a medical patent pertaining to an immobilizer as one of the assets of Arrow-Head Plastics, which interest in the said medical patent he still owns and uses in connection with said business; and (2) Opsahl and Johnson each received an interest in a business venture known as the Organic Fertilizer Project during calendar years 1964 and 1965 and thereby each acquired an undivided interest in a patent for the production of fertilizer and that Opsahl and Johnson each subsequently abandoned their interest in such business venture and their interest in said patent. During the entire period that MacDonald, Opsahl, Johnson, and Zenith held their interest in the Chapman patents, each held the Chapman patents for the production of income and not for sale to customers in the ordinary course of their respective trades or businesses.

OPINION

This case arises out of a series of transfers of various rights in a group of patents.

Ealph Chapman invented a process for the inexpensive manufacture of hardboard, and secured United States and Canadian patents for the process. Chapman granted a license to Canadian Forest Products Ltd. to use the patented process for the production of hardboard in British Columbia. He then assigned all his interest in the United States patents and all his remaining interest in the Canadian patents to C.F.U., a corporation controlled by him. C.F.U. granted a royalty-free license to Chapman Manufacturing, a partnership, to use the process to manufacture hardboard at its plant in Corvallis, Oreg., and to sell the product anywhere. This license was assignable with the plant. C.F.U. then granted a license to Duluth-Superior (a corporation owned equally by the petitioners) to use the process in certain midwestern States.

Duluth-Superior granted a sublicense to Superwood, another corporation owned equally by the petitioners. Superwood received the right to produce hardboard at its Duluth, Minn., plant at a royalty five times as great as that paid by Duluth-Superior to C.F.U.

In June 1951, Duluth-Superior was dissolved, with the license from C.F.U. and the sublicense to Superwood passing into the hands of the petitioners. Also in June 1951, Chapman Manufacturing Co. sold its plant in Corvallis, Oreg. The nonexclusive license which Chapman Manufacturing had held passed to the purchasers of the plant. By the terms of the license agreement between C.F.U. and Duluth-Superior, upon the sale of the Corvallis plant by Chapman Manufacturing, the territorial restrictions in the Duluth-Superior’s license lapsed. However, Superwood was still restricted to producing at its Duluth plant.

About 10 years later, in January 1961, C.F.U. transferred all of its interest in the patents to the petitioners for the sum of $250,000. Shortly thereafter, in October 1961, petitioners transferred all of their interest in the patents to Superwood.

The result of this final transaction was that Superwood held the United States patents, subject only to the royalty-free license which C.F.U. had granted to the owners of the Corvallis, Oreg., plant (which had changed hands). Superwood also held the Canadian patents subject only to the British Columbia license held by Canadian Forest Products.

In his opening statement, respondent’s counsel indicated that he might attack the transfer from petitioners to Superwood as a sham transaction. However, on brief, respondent appears to have abandoned this argument, saying: “Bespondent does not deny that said petitioners transferred to Superwood on October 6, 1961, their respective interests in said patents received from C.F.U. on January 31,1961.”

Bespondent’s primary position is that petitioners may treat the amounts received from Superwood as capital gains only if there was a sale of the patents; and that there was a sale of the patents only if all substantial rights in the patents were transferred by the petitioners. To the contrary, petitioners’ position is that they sold 100 percent of whatever they received from C.F.U., and that if it was not an inventory item, then they may treat the transaction as the sale of capital or section 1231 assets. We agree with the petitioners.

While acknowledging that petitioners are not “holders” of patents within the scope of section 1235, respondent nevertheless contends that the regulations under section 1235 should apply “by analogy.” Specifically, respondent refers to section 1.1235-2 (b) (1), Income Tax Begs.:

(b) All substantial rights to a 'patent. (1) The term “all substantial rights to a patent” means all rights (whether or not then held by the grantor) which are of value at the time the rights to the patent (or an undivided interest therein) are transferred. The term “all substantial rights to a patent” does not include a grant of rights to a patent—
(i) Which is limited geographically within the country of issuance;
(ii) Which is limited in duration by the terms of the agreement to a period less than the remaining life of the patent ;
(iii) Which grants rights to the grantee, in fields of use within trades or industries, which are less than all the rights covered by the patent, which exist and have value at the time of the grant; or
(iv) Which grants to the grantee less than all the claims or inventions covered by the patent which exist and have value at the time of the grant.
The circumstances of the whole transaction, rather than the particular terminology used in the instrument of transfer, shall be considered in determining whether or not all substantial rights to a patent are transferred in a transaction.

We note that subdivisions (i) and (iii) of that regulation have been held invalid by this Court. See Vincent B. Rodgers, 51 T.C. 927 (1969); Thomas L. Fawick, 52 T.C. 104 (1969), revd. 436 F.2d 655 (C.A. 6, 1971). In the Rodgers opinion we said:

By its use of the phrase “property consisting of all substantial rights to a patent,” we do not think Congress intended to import into section 1235 any further or different impediments to capital gains treatment than were contained in section 117 of the 1939 Code. * * *

That language throws at least some doubt on the first sentence of the regulation as well.

Until the regulations under section 1235 confused the area, it was understood that to ask whether there was a transfer of “all substantial rights” was to ask if there had been a sale of the patent. See Vincent B. Rodgers, supra at 929, fn. 2; Fawick v. Commissioner, supra; 3B Mertens, Law of Federal Income Taxation, sec. 22.133 (1970 Supp.). In patent law the sale of a patent is commonly accomplished by granting an exclusive license for the life of the patent. It is sometimes difficult to distinguish sales from licenses.

The issue of whether all substantial rights have been transferred (that is, whether there has been a sale) should arise only when the transferor has retained rights of some sort. In fact, most of the cases seem to be of this type. See cases cited in Mertens, supra. However, respondent has convinced one court that 'under section 1235, “all substantial rights” refers to 100 percent of the original patent rights and that a transfer of all remaining rights (taxpayer had granted a prior nonexclusive license) would not qualify for capital gains. First National Trust & Savings Bank of San Diego v. United States, 200 F. Supp. 274 (S.D. Cal. 1961). But we think the better view is that the transfer of all remaining rights in a patent is a sale entitled to capital gains treatment if it meets the provisions of section 1221 or 1231. Bell Intercontinental Corp. v. United States, 381 F. 2d 1004 (Ct. Cl. 1967).

In any event, petitioners in this case transferred 100 percent of any patent rights which they ever held. This property was not held primarily for sale to customers; and it was held for more than 6 months. We conclude that the sale of it qualifies for capital gains treatment under section 1231 or 1221. Cf. C. A. Norgren Co. v. United States, 268 F. Supp. 816 (D. Colo. 1967); Armco Steel Corp. v. United States, 263 F. Supp. 749 (S.D. Ohio 1966).

Bespondent’s alternative position is that the obligation from Su-perwood to petitioners in the agreement of sale had an ascertainable fair market value, and that to the extent of such fair market value the petitioners received income in the year of sale. With respect to this issue, which was raised by amended answers and which involves increased deficiencies for 1961, respondent bears the 'burden of proof. Buie 32, Tax Court Buies of Practice; Kimbell-Diamond Milling Co., 10 T.C. 7 (1948); Beck Chemical Equipment Corp., 27 T.C. 840 (1957).

Petitioners, who reported the transaction as an installment sale, argue (1) that the obligation had no ascertainable fair market value, (2) if it had an ascertainable fair market value, the petitioners, who use the cash method of accounting, received income only when the payments were received, and (3) if the obligation had a fair market value, the initial payments were less than 30 percent of that amount, so that the transaction qualified as an installment sale.

“There is nothing inherent in contract or claim for the future payment of indefinite amounts that causes it to be insusceptible of valuation.” John W. Chamberlin, 32 T.C. 1098, 1106 (1959), affd. 286 F. 2d 850 (C.A. 7, 1960). “The fair market value of property is a question of fact, but only in rare and extraordinary cases will property be considered to have no fair market value.” Sec. 1.1001-1 (a), Income Tax Kegs. Although in patent cases taxpayers are very often able to establish that production-type payment agreements are not susceptible of valuation, the courts have found valuations where taxpayers have failed to carry that burden, Slater v. Commissioner, 356 F. 2d 668 (C.A. 10, 1966); Chamberlin v. Commissioner, supra, or where the history of payments provides sufficient facts to establish a value. Marsack's Estate v. Commissioner, 288 F. 2d 533: (C.A. 7, 1961). See also Stephen H. Dorsey, 49 T.C. 606, 630-631 (1968), where this Court recognized the usefulness of “experience” in an “established industry” in providing “criteria for ascertaining fair market value.”

Noting that the hardboard industry predated the Chapman process for producing hardboard, and relying on the fairly stable rate of growth in the payments by Superwood under the sublicense, respondent argues that there is sufficient experience and history present in this case to ascertain the fair market value of the patents.

At first glance respondent’s contention seems appealing, but it loses its force when the facts contained in this record are carefully considered. First, the agreement of October 6,1961, did not simply convert a license into a sale, upon the same terms. Although the production-payment schedule remained the same, all limitations on production were removed. Under the sublicense Superwood was authorized to produce only at its Duluth plant. After acquiring the patents, Super-wood could produce anywhere. Presumably the ability to produce in new geographic areas carried with it the possibilities of expanding markets. At least respondent has not shown otherwise. Thus the history of production and payments by the Duluth plant under a limited sublicense, without more facts, gives no indication of production possibilities on a national scale.

While the history of the Duluth plant may provide a method of determining some minimum value for the patents, it would not be the fair market value. And if, as respondent contends, receipts in excess of this ascertained value are reportable as ordinary income (he relies on Osenbach v. Commissioner, 198 F.2d 235 (C.A. 4, 1952)), it would be inappropriate for us to assign to the patents a minimum value which, is likely to be less than fair market value. Certainly we would not be justified in closing the transaction simply because we believed the fair market value to be at least $1.

In fact the Duluth plant did not continue to be the sole production site for Superwood. In 1962 it acquired the stock of Little Nock Hardboard, Inc., and by 1969, Little Nock Hardboard accounted for production payments of $195,000, compared to payments of $500,000 by Superwood.

Nespondent also points out that 8 months before the transfer in question, petitioners purchased the identical property for $250,000 from C.F.U. Hence respondent argues: (1) That $250,000 represented the lump-sum value of petitioners’ obligation to pay C.F.U. royalties of X dollars per square foot of hardboard produced; (2) that Superwood is obligated under the terms of the sale to pay 4X dollars per square foot of hardboard produced; and (8) thus the value of Superwood’s obligation must be at least $1 million.

We think respondent’s approach is too simple. First, under their license petitioners were obligated to pay royalties until about May 1965, when their license expired. Consequently, in purchasing the patents they acquired not only a release from their royalty obligations, but also the right to use the process from 1965 until the patents expired, in 1968 through 1971. Second, by the terms of sale Superwood is obligated to pay until May 31, 1970. Thus the periods of payment are not of comparable length, nor are the total amounts to be paid comparable. Third, petitioners had a license of national scope, extending for less than the life of the patents. Superwood had a sublicense limited in territory to Duluth, but with payments extending into 1975.

Although petitioners and Superwood each held identical interests after their purchases, they held different interests at the start of negotiations, so that they paid for different bundles of additional rights. The price paid by one does not show the value of what the other received, nor does the price paid by either necessarily reflect the value of the whole bundle of patent rights. Finally, some courts have expressed concern as to whether the value of one side of an exchange is necessarily determinative of the value of the other side of the exchange. See Seas Shipping Co. v. Commissioner, 371 F.2d 528, 529-530 (C.A. 2, 1967); Philadelphia Park Amusement Co. v. United States, 126 F. Supp. 184 (Ct. Cl. 1954). Here respondent weds the risks of barter-equation valuation with those of extrapolation.

Nespondent’s witnesses evaluated the agreement of sale by extrapolating from the history of payments by Superwood’s Duluth plant. They did not take into account the possibility of new plants and expanded markets. Nor did they place any emphasis on the threats of production lost by strikes, fires, or other problems. We think that to a company producing at one or two plants, and selling 80 to 40 percent of its production to automobile manufacturers, such risks are substantial. It would be difficult to shift or to make up lost production. And where the patents will eventually expire, production must be made up within a limited period of time or be lost in part to competition.

In short, we think the history of payments from the Duluth plant and the prior purchase from C.F.U. provide insufficient facts for ascertaining the fair market value of the obligation of Superwood. The issue is one of fact. Marsack's Estate v. Commissioner, supra. Based on the facts before us, the case is one where it is appropriate that “the liability for income tax ultimately * * * be fairly determined without resort to mere estimates, assumptions, and speculation.” Burnet v. Logan, 283 U.S. 404, 412 (1931). Under these particular circumstances we conclude that respondent has failed to sustain his burden of proving that the contract in question had an ascertainable fair market value in 1961. Since it had no ascertainable fair market value, “the transaction was not a closed one” in that year. Burnet v. Logan, supra at 413.

In view of this conclusion, it is unnecessary for us to decide whether the installment sale provisions may be used where there is no fixed contract price. It is also unnecessary for us to determine whether fair market value and equivalent to cash are interchangeable terms.

       The Issue In Fawich Is not before us here, for petitioners in this case retained no rights in the patents whatsoever, beyond the right to be paid for them. But in view of the apparent, indeed gratuitous, damage done to Rodgers by the Court of Appeals, and to our position that a patent is divisible at least in some ways, we think it appropriate to discuss the Fawich ease.
      We think the opinion of the Court of Appeals is consistent with our view that “transfer of all substantial rights in the patent” is equivalent to “sale of the patent.” The issue in Fawick and Rodgers was whether there may be a sale of parts of a patent, and what shapes the parts may take. In Rodgers we held that a patent is divisible and salable geographically. In Fawich we held that it was divisible and salable by fields of use. In deciding Rodgers, we thought it was well-established that a patent could be divided into geographic parts. Waterman v. MacKenzie, 138 U.S. 252, 255 (1891); Ellis, Patent Assignments sec. 65 (1955 ed.). In deciding Fawick, we relied upon our earlier opinion in, William S. Rouverol, 42 T.C. 186 (1964), wherein we cited cases approving the division and sale of patents by fields of use.
      If “The monopoly right granted by the patent is the right to exclude others from making, using, or selling the Invention,” we see nothing inherently indivisible about such right. Waterman v. MacKenzie, while suggesting that patents may not be divided for purposes of sale along other than “authorized” lines, nonetheless lists geographic division as authorized. See also 35 U.S.C. sec. 261 (1970 supp.). Thus, although the cases are similar in a broad sense, we do not agree with the Court of Appeals for the Sixth Circuit that Rodgers involved “essentially the same issue” as Fawick.
      
     
      
       The Court of Claims, considering a case where the patent transferor had granted a prior “non-exclusive and irrevocable limited license” said: “By analogy, the Houde transaction would thus seem no different in principle than one in which grantor conveys a fee simple interest in land, subject to an irrevocable easement in perpetuity the grantor had previously conveyed to a third party.” (381 F.2d 1013.) This argument by analogy applies more strongly here where the transferors acquired the patent already subject to the license, and had no royalty interest after the transfer.
