Application of Vincent J. Frilette and Paul B. Weisz

412 F.2d 269, 56 C.C.P.A. 1262
Court of Customs and Patent Appeals·Decided June 26, 1969·No. Patent Appeal 8157·Published·Cited by 4 cases

Opinion

BALDWIN, Judge.

Frilette and Weisz appeal from the Patent Office Board of Appeals decision affirming the examiner’s rejection of claims 166-170, 173, 174, 187, 188, 191, and 193-198 of their application 1 as unpatentable over Plank ’249 2 under 35 U.S.C. § 102(e) or at least 35 U.S.C. § 103, or on the ground of double patent *270 ing in view of the claims of Plank ’253, 3 assigned to appellants’ assignee.

THE INVENTION

The invention relates to porous, crystalline aluminosilicates, sometimes referred to as “molecular sieves,” which have particular value in the catalytic cracking of hydrocarbon oils. The compositions of the present invention, which may be referred to as acid-metal alumi-nosilicates, have an acid moiety supplied by a non-metallic cation, such as hydrogen or ammonium ion, and a metal moiety supplied by a metal cation having a valence greater than one which is selected from metals of Group IB through VIII of the Periodic Table. The compositions are prepared by treating a crystalline aluminosilicate with a solution containing the desired cations until such time as the sodium level of the aluminosilicate is reduced and the alumi-nosilicate is base exchanged to contain combinations of the aforementioned nonmetallic and metallic cations.

THE REFERENCES

The ’249 patent, relating to alumi-nosilicate catalyst compositions for hydrocarbon conversion, contains the following disclosure which was particularly relied upon by the examiner: 4

Base-exchange required for introducing the necessary replacing ions is carried out for a sufficient period of time and under appropriate temperature conditions to replace at least about 90 percent of the alkali metal originally contained in the alumino-silicate and to effectively reduce the alkali metal content of the resulting composite to below about 1 weight percent. It is contemplated that any ionizable compound of a metal capable of replacing the alkali metal may be employed for base-exchange either alone or in combination with other ions. Compounds will be used wherein the replacing ion is in the cationic state. Inorganic salts will usually be employed. Suitable materials include soluble compounds of calcium, magnesium, manganese, vanadium, chromium, cerium, aluminum, lanthanum, praseodymium, neodymium, samarium and other rare earths, as well as solutions containing mixtures of these ions and mixtures of the same with other ions, such as ammonium. Organic salts of the foregoing metals, such as acetate and formate may also be used, as well as very dilute or weak acids. A particularly effective base-exchange solution is one containing calcium and ammonium ions in a ratio in the range of 20/1 to 0.5/1 and preferably 10/1 to 1/1, to effect replacement of the alkali metal ion with calcium and ammonium ions.

If available as a reference, the effectiveness of the ’249 patent, filed prior to appellants' filing date, was conceded by appellants before the board as follows:

Appellants concede that if the Plank and Rosinski “249” patent is available as a reference, the appealed claims would be obvious to one of ordinary skill in the art unless the cross-referencing thereof under Rule 79 is found sufficient to remove that patent.

The ’253 patent, filed subsequent to appellants’ filing date, has a disclosure similar to that of the application on appeal; however, the scope of the claims is different in that the metals of Group *271 IB through VIII (as recited in the claims here on appeal) are, in the ’253 patent, restricted to the rare earth metals of those groups.

INVENTORSHIP

Certain portions of the record are now summarized as they bear upon an important aspect of this case, namely, the inventorship of the subject matter involved in the present application and the ’249 patent and the priority thereof.

The present application was originally filed as the joint invention of four inventors, Frilette and Weisz, appellants herein, and Plank and Rosinski, the reference patentees. During the course of prosecution, it was determined that Plank and Rosinski had been incorrectly joined as inventors, and an amendment to correct the misjoinder was filed, accompanied by an affidavit of the four originally-named inventors pursuant to Rule 45(b) 5 of the Patent Office Rules of Practice. That affidavit was considered defective by the examiner for failure to state sufficient facts to establish that the misjoinder had been made through error and without deceptive intention; so a second Rule 45(b) affidavit was filed, approved by the examiner, and entered. That second affidavit, executed by Frilette, Weisz, Plank, and Rosinski, includes the following statements:

That in connection with the filing of the above-identified application, we have reviewed our recollection and laboratory records relating to the subject matter of application Serial No. 161,-242 and as a result thereof, we have determined that said CHARLES J. PLANK and EDWARD J. ROSIN-SKI did not work conjointly with VINCENT J. FRILETTE and PAUL B. WEISZ in conceiving crystalline aluminosilicate compositions which contain both hydrogen ions, or ions capable of conversion thereto, in combination with cations of metals selected from Group IB through Group VIII of the Periodic Table, the method of preparing such compositions and the use of the same for the conversion of hydrocarbons.
