SMITH, Judge.
The appealed claims stand rejected by the examiner on two grounds which were affirmed by the board: (1) “double patenting,” and (2) obviousness of the appealed claims in view of the prior art reference of record. Our disposition of this appeal requires that we consider only the rejection based on “double patenting.”
A statement of the subject matter defined by the appealed claims is set forth in appellant’s brief:
The invention relates to a novel composite polymeric material consisting of wood fibers or cellulose fibers isolated from wood having a guest polymer of an olefinically unsaturated monomer deposited in situ within the host material. The product which is claimed consists of wood fibers or cellulose fibers isolated from wood having a guest polymer deposited in situ within the fibers, as distinguished from prior art compositions in which wood or wood fibers have been used as fillers for molded or cast plasties or in which plastics have been formed within the macroscopic spaces between the wood fibers.
The facts which gave rise to the “double patenting” rejection are not in dispute. On March 4, 1958 appellant filed two patent applications. One application has since resulted in a U. S. Patent.
Claims 60, 61, 78 and 80 of this patent are relied on in the “double patenting” rejection. These claims are of the product-by-process type. The other application
contains the claims here on appeal. They define a product per se as described above.
The parties agree that the product defined by the appealed claims is the same
product defined in the product-by-process claims subject to certain “qualifications” as stated by appellant:
* * * The appealed claims are broader than the product claims of the Bridgeford patent in that no process steps are recited, but are more specific with regard to the host material. * * *
It is clear from the record, and appellant does not argue otherwise, that the process disclosed in the appealed application is the same process disclosed in the issued patent. It is this process which is disclosed as making the product defined by the appealed claims and the patent claims. We thus do not have presented the issue of whether the product defined in appealed claims is a
different
product than that defined by the patent claims because made by a different process.
The examiner’s position and reasoning, affirmed by the board, was as follows:
* * * It is the Examiner’s view that there is only one inventive concept in the appealed claims and the article claims 60, 61, 78, and 80 of appellant’s patent. Although the article claims of the patent are restricted to the form of “product-by-process” claims and the appealed article claims are not so limited, nevertheless the appealed claims and the patent claims are both for the same invention. * * * Since appellant has obtained article claims of the “product-by-process” type in his patent, it is considered that appellant is not entitled to the appealed article claims without such process limitations, because both the appealed application and the appellant’s patent disclose one and the same invention.
* * * * *
Appellant contends * * * that the appealed article claims lie in an effectively different statutory class from the “product-by-process” article claims of the patent but has not cited any authority to support this contention. Appellant’s position appears to be wholly inconsistent with the decisions in Ex parte Painter, 1891 C.D. 200 and Ex parte Scheckner 1903 C.D. 315. Product-by-process claims are still product claims.
Appellant’s arguments in regard to the “double patenting” rejection are twofold: first, because of the substantial differences in
scope
between the appealed claims and the patent claims (particularly because the appealed claims are product claims without process limitations) there are present two inventions each of which is entitled to a patent; second, because a terminal disclaimer has been filed in this case, the extension of monopoly basis of the “double patenting” rejection has been eliminated.
The solicitor argues in his brief that any terminal disclaimer would be ineffective because the appealed claims are directed to the same subject matter as in the patent claims.
We think the dispositive issue in this appeal is whether the nature of the “double patenting” rejection here is such, that the terminal disclaimer remedy provided in section 253 is appropriate.
Our decisions in In re Robeson, 331 F.2d 610, 51 CCPA 1271; and In re Kaye, 332 F.2d 816, 51 CCPA 1465, recognize the principle that where
separate
inventions are involved, a terminal disclaimer is effective to overcome a “double patenting” rejection. In
Robeson
this court pointed out it was not apparent that Congress, in enacting the terminal
disclaimer provision of 85 U.S.C. 253, had abandoned the principles found in Miller v. Eagle Mfg. Co., 151 U.S. 186, 14 S.Ct. 310, 38 L.Ed. 121 (1894) and Underwood v. Gerber, 149 U.S. 224, 13 S.Ct. 854, 37 L.Ed. 710 (1893). The court concluded that “[w]here the claims of a second application are substantially the same as those of the first patent, they are barred under 35 U.S.C. § 101.” (331 F.2d at 614, 51 CCPA at 1274).
The solicitor here asserts that the appealed claims are drawn to cover the
same
invention as that defined in the patent claims. He reasons therefore that the bar under 35 U.S.C. § 101, referred to in
Robeson,
is present here.
A product-by-process type claim defining an article of manufacture was permitted at least as early as 1891 in Ex parte Painter, 1891 C.D. 200, 57 O.G. 999 where Commissioner Simonds stated:
It requires no argument to establish the proposition that
as a rule
a claim for an article of manufacture should not be defined by the process of producing that article. On the other hand, when a man has made an invention his right to a patent for it, or his right to a claim properly defining it, is not to be determined by the limitations of the English language. When the case arises that an article of manufacture is a new thing, a useful thing, and embodies invention, and that article cannot be properly defined and discriminated from the prior art otherwise than by reference to the process of producing it, a case is presented which constitutes a proper exception to the rule.

Our decisions in In re Robeson, 331 F.2d 610, 51 CCPA 1271; and In re Kaye, 332 F.2d 816, 51 CCPA 1465, recognize the principle that where
separate
inventions are involved, a terminal disclaimer is effective to overcome a “double patenting” rejection. In
Robeson
this court pointed out it was not apparent that Congress, in enacting the terminal
disclaimer provision of 85 U.S.C. 253, had abandoned the principles found in Miller v. Eagle Mfg. Co., 151 U.S. 186, 14 S.Ct. 310, 38 L.Ed. 121 (1894) and Underwood v. Gerber, 149 U.S. 224, 13 S.Ct. 854, 37 L.Ed. 710 (1893). The court concluded that “[w]here the claims of a second application are substantially the same as those of the first patent, they are barred under 35 U.S.C. § 101.” (331 F.2d at 614, 51 CCPA at 1274).
The solicitor here asserts that the appealed claims are drawn to cover the
same
invention as that defined in the patent claims. He reasons therefore that the bar under 35 U.S.C. § 101, referred to in
Robeson,
is present here.
A product-by-process type claim defining an article of manufacture was permitted at least as early as 1891 in Ex parte Painter, 1891 C.D. 200, 57 O.G. 999 where Commissioner Simonds stated:
It requires no argument to establish the proposition that
as a rule
a claim for an article of manufacture should not be defined by the process of producing that article. On the other hand, when a man has made an invention his right to a patent for it, or his right to a claim properly defining it, is not to be determined by the limitations of the English language. When the case arises that an article of manufacture is a new thing, a useful thing, and embodies invention, and that article cannot be properly defined and discriminated from the prior art otherwise than by reference to the process of producing it, a case is presented which constitutes a proper exception to the rule.
On the basis of the reasoning in
Painter,
claims of the product-by-process type defining a chemical compound were allowed in Ex parte Fesenmeier, 1922 C.D. 18, 302 O.G. 199.
The rationale stated in the above decisions which permit the product-by-process type claim in ex parte prosecution before the Patent Office is clear: the right to a patent on an invention is not to be denied because of the limitations of the English language, and, in a proper case, a product may be defined by the process of making it. However, the invention so defined is a
product
and not a
process.
To this we would add that, similarly, the limitations of known technology concerning the subject matter sought to be patented should not arbitrarily defeat the right to a patent on an invention. Whether the invention be defined in terms of the structure of the compound, or its novel physical characteristics, or by defining it in terms of the process by which it is produced or in a proper case, by employing more than one of these methods of defining the invention, the right to a patent on the invention is the ultimate consideration, subject to the conditions set forth in 35 U.S.C. § 112. “In a proper case” does not mean that an applicant
must prove the impossibility of defining the invention other than by using more than one of the above methods.
The fact here is that the invention defined by the product-by-process claim of the issued patent is the same invention defined as a
product
in the appealed claims.
In In re Siu, 222 F.2d 267, 42 GCPA 864, this court quoted with approval the statement of the board that:
* * * The evils of double patenting where the two patents do not issue on the same date include that of extension of monopoly but this is not the only objection to double patenting. The pertinent statutes do not, in our opinion, warrant the allowance of more than one patent for a single invention independently of the question of extension of monopoly. * * *
We find this statement applicable here. Since a terminal disclaimer, at best, meets only the extension of monopoly objection to double patenting, it cannot overcome a double patenting rejection based on the underlying statutory concept that there shall be but one patent for one invention.
Since the appealed product type claim and the product-by-process type patent claims define the same patentable subject matter, differing only in scope, they may not be allowed in separate applications. 35 U.S.C. § 101. See In re Robeson, supra.
The decision of the board is affirmed.
Affirmed.
