John Kollar appeals from the final decision of the United States Patent and Trademark Office (“PTO”) Board of Patent Appeals and Interferences holding the claims in Kollar’s Patent Application No. 08/657,564 to be unpatentable under the on-sale bar of 35 U.S.C. § 102(b). In re Kollar, No. 96-C-7375 (Bd. Pat.App. & Inter. July 25, 2001) (“Kollar III”). Because the Board erred in determining that the process claimed in the '564 application was on sale within the meaning of § 102(b), we vacate and remand.
BACKGROUND
The '564 application, filed on December 5,1995, is directed to a process for preparing a dialkyl peroxide by reacting one or more alcohols and/or an olefin with a mo-noalkyl hydroperoxide in the presence of an effective amount of an insoluble, heterogeneous acidic catalyst and separating the reaction mixture from the catalyst. The '564 application describes the claimed process as a low-cost method of producing various dialkyl peroxides, such as di-ierf-butyl peroxide, which in turn can be used to make, inter alia, ethylene glycol. Ethylene glycol is used in the manufacture of a number of commercial products, ranging from polyester fibers to mining explosives. Claim 1 of the '564 application, the only claim at issue in this appeal, 1 reads as follows:
1. A process for the preparation of a dialkyl peroxide comprising reacting one or more members selected from the group consisting of an alkylating alcohol of the formula ROH, and an olefin of the formula (R2)(R2a)C=C(R3)(R3a), wherein R is Cí.Cío alkyl, and R2, R2a, R3, and R3a are independently selected from hydrogen and CrCio alkyl; with a hydroper-oxide of the formula R^OH, wherein is R1 is Cx-C10 alkyl; in the presence of an effective amount of a substantially solid, insoluble, heterogenous [sic] acidic catalyst; followed by separation of the reaction mixture from said catalyst.
The examiner finally rejected claims 1 through 17 under § 102(b) based upon a purported sale of the invention by Kollar’s assignee, Redox Technologies, Inc., a company owned and operated by Kollar, to Celanese Corporation. 2 Kollar appealed that rejection to the Board.
The Board, in an exhaustive analysis, affirmed the examiner’s rejection of claims 1 through 17 under the on-sale bar of § 102(b). In re Kollar, No. 96-C-7375, slip op. at 47 (BPAI July 17, 2000) (“Kollar I”). The Board determined that a July 1, 1980, agreement between Redox and Cela-nese entitled “DEFINITIVE AGREEMENT” (“the Celanese Agreement”) constituted a firm offer to sell embodiments of the claimed process, thus triggering the bar of § 102(b). Id. In the Celanese Agreement, the parties essentially agreed to share technology and coordinate their research efforts with the ultimate goal of designing and building a commercial plant *1329 capable of implementing the claimed process to manufacture ethylene glycol. The Board determined that § 102(b) applied because Celanese received what it termed “a right to commercialize” Kollar’s invention, and the necessary technical information to utilize that invention, in exchange for a series of royalty payments. Id. The Board further determined that the “sale” by Redox could not be considered to be experimental because there was no provision in the agreement obligating Celanese to experiment with the claimed process, and in any event Rollar admitted on the record that he had reduced the invention to practice prior to the execution of that agreement. Id. at 45.
Rollar thereafter filed a request for rehearing, which resulted in the Board issuing two additional opinions clarifying its rationale for affirming the examiner’s rejection of claims 1 through 17. In re Kollar, No. 96-C-7375 (BPAI Feb. 28, 2001); Kollar III. In Kollar III, the Board further explained its rationale for concluding that the Celanese Agreement barred Rollar from obtaining a patent to the claimed process as follows:
[A]n embodiment of a claimed process can be physically represented by a written description in a document which not only identifies the process but also enables the practice of that chemical process by one of ordinary skill in the art .... [T]he preponderance of the evidence shows that appellant ... transferred documents containing a written description of the claimed process ... [and] thus commercially exploited] the claimed chemical process....
Kollar III, slip op. at 8, 9 (emphases added).
Rollar appeals from the Board’s final decision. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(4)(A).
DISCUSSION
Section 102(b) provides in relevant part that “[a] person shall be entitled to a patent unless ... the invention was ... on sale in this country, more than one year prior to the date of the application for patent in the United States....” 35 U.S.C. § 102(b) (1994). The Supreme Court established a two-prong test governing the application of the on-sale bar: “First, the product must be the subject of a commercial offer for sale.... Second, the invention must be ready for patenting.”
Pfaff v. Wells Elecs., Inc.,
On appeal, Rollar primarily argues that Redox’s and Celanese’s intended activities, as called for by the Celanese Agreement, were experimental in nature and thus do not fall within the purview of the on-sale bar of § 102(b). Rollar also contends that the invention was not ready for patenting because it had not been determined whether a commercial plant meeting the quality *1330 specifications necessary to carry out the claimed process could be built. Finally, Kollar argues that the Celanese Agreement was merely a license and therefore did not involve the sale of a commercial embodiment of the invention.
The PTO responds that Kollar failed to carry his burden of proving that the Cela-nese Agreement falls within the experimental use exception to § 102(b). The PTO also contends that the claimed process was ready for patenting because Kol-lar admitted that it was reduced to practice at the time the Celanese Agreement was signed. Finally, the PTO argues that the Celanese Agreement constitutes a sale of the process disclosed in claim 1 because Kollar received royalty payments and licensing rights in certain Celanese technology as consideration for disclosing his process and granting Celanese the “right to commercialize” the invention.
We conclude that the Board erred in determining that the Celanese Agreement constituted a “sale” of the claimed invention within the meaning of § 102(b). Although the Board correctly determined that Kollar’s reduction to practice of the invention rendered it “ready for patenting” under the test set forth in
Pfaff, see 525
U.S. at 67-68,
Although the Celanese Agreement specifically contemplates that “resultant products” manufactured using the claimed process could
potentially
be sold, nowhere in the Celanese Agreement is there an indication that a product of the claimed process was actually offered for sale. Rather, that agreement constitutes a license

to Celanese under any future patents relating to Kollar’s invention. We
*1331
have held that merely granting a license to an invention, without more, does not trigger the on-sale bar of § 102(b).

involved a patented security lock that had been the subject of a commercial transaction that took place prior to the critical date.
Therefore, although in
Mas-Hamilton
we set forth a number of bases upon which to affirm the district court’s determination that there was no on-sale bar, we squarely addressed the issue “whether Mosler was merely a potential licensee of
*1332
legal rights, or, rather, a potential customer of devices” in concluding that the offer of a license of patent rights did not trigger the on-sale bar.

at 1216, 48 USPQ2d at 1019. The Board in this case, although correctly stating that “[t]he ‘commercial offer for sale’ of an embodiment of a claimed invention is all together [sic] different than an offer to sell or assign

of the rights

the invention,”

The Board also erred in failing to recognize the distinction between a claim to a product, device, or apparatus, all of which are tangible items, and a claim to a' process, which consists of a series of acts or steps. A tangible item is on sale when, as we held in
Group One,
the transaction “rises to the level of a commercial offer for sale” under the Uniform Commercial Code.
A process is thus not sold in the same sense as is a tangible item. “Know-how” describing what the process consists of and how the process should be carried out may be sold in the sense that the buyer acquires knowledge of the process and obtains the freedom to carry it out pursuant to the terms of the transaction. However, such a transaction is not a “sale” of the invention within the meaning of § 102(b) because the process has not been carried out or performed as a result of the transaction. The same applies to a license to a patent covering a process. The Board in this case failed to recognize this distinction, and therefore erred in concluding that the license to the process under any future patents, and the accompanying description of that process, constituted a sale of the subject matter of those patents, viz., the process.
The Board’s failure to recognize this distinction is demonstrated by its erroneous reliance on two cases from this court as supporting its determination that Kollar’s invention was on sale within the meaning of § 102(b). In
Kollar I,
the Board cited
Scaltech Inc. v. Retec/Tetra, L.L.C.,
We cannot articulate in advance what would constitute a sale of a process in terms of the on-sale bar. Surely a sale by the patentee or a licensee of the patent
of
a product made by the claimed process would constitute such a sale because that party is commercializing the patented process in the same sense as would occur when the sale of a tangible patented item takes place.
See D.L. Auld Co. v. Chroma Graphics Corp.,
Finally, it is important to recognize that exempting licenses under a patent from the on-sale bar is not inconsistent with traditional policies underlying that doctrine, including:
(1) [the] policy against removing inventions from the public domain which the public justifiably comes to believe are freely available due to commercializa *1334 tion; (2) [the] policy favoring prompt and widespread disclosure of inventions to the public; and (3)[the] policy of giving the inventor a reasonable amount of time following sales activity to determine whether a patent is worthwhile.
In re Caveney,
We therefore reverse the Board’s conclusion that the examiner properly rejected the claims at issue under the on-sale bar. On remand, the Board may inquire whether Kollar, Redox, or any licensee of the invention (e.g., Celanese or ARCO) forfeited Kollar’s right to obtain a patent to the claimed process by offering for sale a product made using that process more than one year prior to filing the '564 application.
See D.L. Auld,
Because we conclude that the Board erred in its basis for determining that the Celanese Agreement constituted a “sale” within the meaning of § 102(b), we need not address whether any activities undertaken by Celanese and/or Redox pursuant to that agreement fall within the experimental use exception to § 102(b).
CONCLUSION
Because the Board erred in affirming the examiner’s rejection of claims 1 through 17 under the on-sale bar of § 102(b), we
VACATE AND REMAND.
Notes
. Because Kollar argued only that claim 1 was not barred under § 102(b) in his principal brief to the Board, and because he stated that “claims 1-17 all stand together,” claim 1 is the only claim we will discuss in this appeal.
. The examiner also rejected claims 1 through 17 based upon an alleged sale by Redox to ARCO Chemical Company. The Board, however, did not affirm the examiner's rejection on the basis of that transaction.
. We use the term "license” here to refer to rights under a patent, not to describe a commercial transaction arranged as a "license” or a "lease” of a product or a device that may or may not have been patented.
See Group One, Ltd. v. Hallmark Cards, Inc.,
. Although D.L. Auld and W.L. Gore involved the forfeiture of patent rights due to sales by patentees or assignees, we see no reason why that rule should not equally apply to licensees of those parties.
. The fact that Celanese’s license could potentially be exclusive or nonexclusive does not alter our analysis. Both types of licenses involve only rights under any future patent, and in neither case is a product of the claimed process actually offered for sale.
