Laurence & Laurence, Herbert I. Sherman, Washington, D. C. (Dean Laurence, Washington, D. C., of counsel), for appellant.

Before WORLEY, Chief Judge, and RICH, MARTIN, and SMITH, Judges, and Judge WILLIAM H. KIRKPATRICK.*
This appeal is from the decision of the Board of Appeals of the United States Patent Office affirming the rejection by the Primary Examiner of claim 1 of appellant's application No. 518,340 filed June 27, 1955 for a patent on a condensation product of hexachlorocyclopentadiene. The appealed claim is as follows:
The reference discloses the claimed dimer of hexachlorocyclopentadiene and, since it was published more than one year prior to the filing date of the instant application, it is a statutory bar under 35 U.S.C. § 102(b) unless appellant is entitled under 35 U.S.C. § 120 to rely upon the filing date of his earlier application No. 757,321, filed June 26, 1947 on which patent No. 2,724,730 was granted November 22, 1956. The earlier application was copending with the appealed application and was filed less than a year after the date of the reference.
The issue here is whether appellant is entitled to rely upon 35 U.S.C. § 120 to secure for the present application the benefit of the filing date of the earlier application. The resolution of this issue requires us to determine whether the invention here claimed was disclosed in the earlier application "in the manner provided by the first paragraph of section 112" of 35 U.S.C.
The examiner and the board have held that the earlier application did not disclose the invention here claimed as required by section 120 and stated that the earlier application contained no disclosure of utility for the product here claimed. Appellant asserts that any person skilled in the art to which the claimed invention pertains would be able, with the teachings of the earlier application before him, to use the product 1) as chemical intermediates for organic synthesis, 2) for solvent uses and 3) for the preparation of toxic substances such as "insecticides, fungicides, etc."
No issue has been raised concerning appellant's identification of the claimed compound and disclosure of a method of making it in the earlier application. It is the position of the examiner and the board that the utility of the compound was not sufficiently disclosed therein. The earlier application contains the following assertion of utility:
"The products of the aforesaid process are valuable as chemical intermediates for organic synthesis, for solvent uses and for the preparation of toxic substances such as insecticides, fungicides, etc."
While the examiner and the board both stated that the earlier application did not contain a sufficient statement of the utility of the product here claimed, we find the paragraph just quoted to be sufficient for that purpose. Solvents, intermediates, insecticides and fungicides are products having utility. This meets the utility requirement of 35 U.S.C. § 101. The question remains, however, whether the description of the manner and process of using the compound for these purposes as set forth in the earlier application is sufficient to meet the requirements of the first paragraph of 35 U.S.C. § 112.
We have had occasion to consider the requirements of section 112 at some length and to discuss them in our recent opinion in In re Nelson and Shabica, 280 F.2d 172, 47 CCPA ____. We there stated:
The test for sufficiency of compliance with section 112 as stated in the Nelson and Shabica decision is "what the application as a whole communicates to one skilled in the art." In elaborating on that test we said:
* * *"
It is well settled that an applicant need not expressly set forth in his specification matters which are commonly understood by persons skilled in the art. Webster Loom Co. v. Higgins et al., 105 U.S. 580, 586, 26 L.Ed. 1177; In re Chilowsky, 229 F.2d 457, 43 CCPA 775. As was said in the former case:
"That which is common and well known is as if it were written out in the patent and delineated in the drawings."
Accordingly, if a person of ordinary skill in the art to which the claimed dimer of hexachlorocyclopentadiene relates would understand how the compounds of appellant's prior application can be used as intermediates, solvents, insecticides or fungicides, the disclosure is sufficient. We therefore do not agree in this case with the board's statement:
The issue here is an issue involving adequacy of the disclosures of end uses of the claimed product when tested by the first paragraph of section 112. The reference therein to "any person skilled in the art" requires that we read and interpret the specific disclosures of utility against the background of knowledge possessed by such a person including the knowledge of any inherent utility of the claimed product.
The earlier application discloses utility of the claimed dimer as an intermediate for organic synthesis1 and for solvent uses in addition to its use in the preparation of toxic substances such as insecticides and fungicides. The decision of the board rested on its findings of inadequacy of the disclosures of utility of the claimed dimer as an insecticide and fungicide. As to these two uses, the board, in finding the disclosure of utility insufficient, said:
We do not think this is a correct interpretation of the requirements of section 112. We think the earlier application contains a sufficient disclosure to one skilled in these arts when it states the compounds disclosed may be used to prepare toxic substances "such as insecticides, fungicides, etc."
The terms "insecticides" and "fungicides" are terms of general knowledge and application in this art. A person having the ordinary skills in the art would be presumed to know the meaning of these terms as defined in Hackh's Chemical Dictionary (3rd Ed. 1944) as follows:
Such a person also would be presumed to know the conventional uses of insecticides as described in the Encyclopedia of Chemical Technology, Interscience Publishers Inc. (1951), as follows:
He also would be presumed to know what the same Encyclopedia says of fungicides:
The compounds are described in appellant's earlier application as solids and, it seems to us, therefore, that it would be well within the expected knowledge of those skilled in this art to use the toxic properties of the claimed dimers in these fields. If used as dust, the product may be diluted as desired, with an inert material.
It is true the application does not recite the concentration to be used, nor the particular kinds of insects or fungi to be treated. In our opinion these are matters which could be expected to be within the knowledge of a person of ordinary skill in this art. A reasonable compliance with section 112 does not require that the...
