Opinion

OPINION AND ORDER

WILLIAM C. CONNER, District Judge:

This action seeks a declaratory judgment of the invalidity and non-infringement of U.S. utility patent No. 4,021,891 (“ ‘891 patent”) and U.S. design patents Nos. 247,467 and 247,468 which cover magnetic clasps for women’s handbags and which are owned by defendant Application Art Laboratories (“AAL”) and exclusively licensed to defendant Randolph-Rand Corporation. Defendants have counterclaimed for alleged infringement of the patents in suit by plaintiff.

The action is before the Court on (1) plaintiff’s motion for partial summary judgment and for dismissal of the counterclaims on the ground that the patents in suit are invalid and/or unenforceable (a) because of fraud and inequitable conduct in the prosecution of the applications therefor in the U.S. Patent and Trademark Office (“PTO”) in failing to call to the attention of the PTO examiner prior patents and publications which were cited against the applications for corresponding German and Japanese patents, and (b) because the claims of the ’891 patent are fully anticipated by both cited and uncited prior art; and (2) defendants’ cross-motion for summary judgment dismissing the complaint on the ground of res judicata.

Both motions are denied in all respects.

The patented inventions

The ’891 patent was issued to AAL on an application filed April 18, 1974 in the name of Tamao Morita of Tokyo, Japan. It covers a magnetic clasp having two separable parts, one of which is attached to the body of a handbag and the other of which is attached to the flap. The “female” part includes a permanent magnet, for example of cylindrical shape, with opposite planar faces of opposite polarity, and with a hole, for example of cylindrical shape, extending axially through the magnet from one face to the other. The remote face of the magnet is covered by a ferromagnetic pole plate which extends across one end of the hole. The “male” part consists of a ferromagnetic pole plate which is adapted to overlie the adjacent face of the magnet and which has projecting from its inner face a ferromagnetic rod of the same shape as the hole and of slightly smaller-cross-sectional size so as to fit into the hole and of such length that its outer end can contact the pole plate on the female part when the pole plate on the male part is near or just touches the adjacent face of the magnet. This completes a ferromagnetic path from one pole plate through the hole in the magnet to the opposite pole plate and concentrates the magnetic flux to increase the magnetic attraction between the two parts and their resistance to axial separation.

The projection of the rod on the male part into the hole in the magnet of the female part provides a mechanical interlock which prevents lateral sliding movement of the two parts relative to one another and provides a more secure closure.

In an alternative construction, the pole plate on the female part is also provided with a ferromagnetic rod shaped and sized to fit into the hole in the magnet and of such length as to project only part way through the magnet. The rod on the male part is correspondingly shortened so that the ends of the two rods come into contact when the pole plate on the male part is near or just touches the adjacent face of the magnet. The rod on the male part likewise projects into the hole in the magnet to provide the mechanical interlocking action described above.

The outer edge and one or both faces of the magnet may be covered with a non-ferromagnetic material, such as brass, to further concentrate the magnetic field of the magnet through the ferromagnetic path as well as improving the appearance of the device and providing means, such as a projecting flange, to facilitate attachment of the parts to a handbag, for example by sewing through holes in the flange.

[363]*363The two design patents in suit, issued to AAL on applications filed December 17, 1975 in the name of Tamao Morita, cover the appearance of the device shown in the utility patent. The designs shown in the two patents are virtually identical except that in one of them the device is of circular cross-sectional shape while in the other it is of rectangular shape.

The cited prior art

The prior U.S. patents to Brett (No. 3,141,216), and Daddona (No. 3,372,443) show magnetic garment clasps which are similar to that of the ’891 patent except that both parts of the clasp include a permanent magnet. Each magnet is of cylindrical shape, with a cylindrical hole extending axially through it, with the remote planar faces of each magnet covered by a circular pole plate of ferromagnetic material with a rod of ferromagnetic material extending axially from each plate through the hole in its magnet, in position to contact the adjacent end of the rod on the mating part. The outer end portion of the rod of the “male” part projects into the hole in the magnet of the “female” part to provide a mechanical interlock and prevent lateral sliding of the two parts relative to one another. In the devices of both Brett and Daddona, the edges and remote faces of the magnets are enclosed in a formed housing which, although not specifically disclosed as such, is presumably of non-ferromagnetic metal. The Brett and Daddona devices would be functionally identical with that of the ’891 patent in suit if the magnet on the male part were eliminated and its rod correspondingly shortened to allow the pole plate on the male part to come into contact with or adjacent to the proximate face of the magnet on the female part.

The prior Robinson U.S. patent No. 2,901,278 bridges this gap. It discloses a magnetic latch for doors in which the “female” part has a permanent magnet of cylindrical shape with a cylindrical hole extending axially through it. Overlying the remote planar surface of the magnet is a circular ferromagnetic pole plate. The “male” part has a circular ferromagnetic pole plate with a ferromagnetic rod projecting axially from it through the hole in the magnet, with the outer end of the rod contacting the pole plate of the female part. However, the rod, instead of being rigidly fixed on the pole plate of the male part, is axially slidable in it and a leaf spring biases the rod outwardly toward the female part so that as the two parts approach one another, the magnetic attraction between them becomes effective while the pole plate of the male piece is still a substantial distance from the proximate surface of the magnet. When the outer end of the rod contacts the pole piece of the female part, the rod slides inwardly relative to the pole piece on the male part, against the resistance of the spring, to allow the male pole piece to engage the proximate surface of the magnet. Although this is not discussed by Robinson, nor significant in a door latch, the projection of the rod on the male part into the hole in the magnet of the female part obviously would provide a mechanical interlock to prevent lateral relative movement of the two parts.

The Robinson device fully anticipates Claim 1, the only independent claim of the ’891 patent in suit, except for the limitation that the rod is “rigidly attached” to the male pole plate.

The cited prior art is therefore quite close to the claims of the '891 patent, and no claims were allowed in the application for the ’891 patent until after all the claims had been repeatedly rejected as obvious in view of this art and a notice of appeal had been filed.
