Opinion

DUFFY, Senior Circuit Judge.

Plaintiffs sought damages and injunc-tive relief for alleged patent infringement [Count I] and for unfair competition [Count II]. The District Court decided for the defendant on each count. In addition, the District Court awarded the defendant the sum of $11,000 as attorney fees on the ground that Count II of the complaint was brought “without justifiable groúnds, was baseless and vexatious.”

Plaintiffs appeal from the judgment dismissing Count I, and the- awarding of attorney fees with respect to Count II. Although plaintiffs state they believe the findings and conclusions of the District Court on the merits of Count II are erroneous, they have not appealed from the judgment dismissing that Count.

Defendant cross-appeals from the judgment insofar as it did not allow the total amount of attorney fees requested in connection with Count II, and further, insofar as it did not allow defendant any attorney fees in connection with successfully defending against Count I. Defendant does not press its appeal for further allowance of attorney fees as to Count II, but insists upon an allowance of attorney fees as to Count I.

The Lofgren Patent in suit, U. S. Patent No. 3,089,182, was issued to Charles W. Lofgren on May 14, 1963. Sanford Research Company is the owner of the patent and has the right by assignment to recover for past infringements. It has licensed Sanford Ink Company under the patent.

The patent in suit relates to a liquid marking device which plaintiffs describe as a throw-away felt-tip marker. These markers use a special volatile ink which enables them to mark upon almost any surface.

All patent drawings and the physical embodiment indicate that the body of the marker shall be a one-piece, seamless, extruded metal shell having an integral bottom and an initially wide-open upper end.

The marker is filled with ink by an injection into a felt pad which retains the ink until used. The pad, sometimes referred to as reservoir, has dimensions similar to those of the shell, and is inserted through the upper end of the shell. The reservoir is then pushed to the bottom of the shell.

The upper end of the shell is then reduced in diameter by subjecting it to a series of reducing dies mounted in a press. This forms the body of the marker with an elongated neck or ferrule portion. This process is referred to as a necking operation.

After the necking operation is completed, a self-supporting wick-like marking ■ element is inserted into the neck. The wick is pushed down until the lower end engages the felt reservoir. Then a “staking” tool is used to pinch parts of the neck inwardly for gripping limited areas of the wick element, thereby retaining the element in position while leaving venting passageways along a side of the wick. Finally, a removable cap is placed over and sealingly engages the outer periphery of the neck portion.

On the issue of validity, the District Court found lack of novelty; also, that the patent was invalid “ * * * because there was no invention in making in *514 tegral that which existed in two or more parts * * * ”; further, that the Lof-gren patent was invalid because it was obvious to a person having ordinary skill in the art, and that Lofgren merely made a selection of elements old in the art unaccompanied by any unexpected improved result. The Court also found misrepresentations by plaintiffs as to the date of the alleged invention, and that a French Patent, No. 1,063,019 issued to Williams et al. was also a bar.

About 1958, Sanford became interested in producing a felt-tip, throw-away marker. The Magic Marker, the Marks-A-Lot marker, the Cado marker and others were examined. Plaintiffs concluded that these markers permitted too much leakage or evaporation of the volatile ink used. Some were too bulky to be comfortably used as a writing instrument or marker. Some were too expensive to produce. The cost of production was an important item in a throw-away marker.

After many months of investigation and experimentation, the Sanford marker was conceived. In the spring of 1959, Sanford contacted Hampton Products in order to obtain Hampton’s aid in placing the Sanford device in production. More particularly, Sanford sought help in assembling the felt reservoir within the impact extruded aluminum shell and subsequently “necking” the upper end of the shell. Hampton’s president, Ward, disclaimed any knowledge of felt-tip marking devices.

Sanford completed and tested specimens of its marker in June, July and August, 1959. Several small but important manufacturing problems were solved. However, it was not until February 1960 that Sanford was able to place its marker on sale to the general public.

One company requested and received a non-exclusive license from Sanford. Several other companies asked Sanford to produce private brand markers for them. Hampton participated in processing more than sixteen million of the Sanford device in a period of some three years.

For some ten years prior to the introduction of the Sanford marker, defendant Eberhard had devoted much time and effort in developing its marker. It had carefully examined and tested the Magic Marker and similar devices then on the market. Plaintiffs claim that defendant ended its ten-year search for something “different and better” by deciding to copy the patented structure.

Defendant, well knowing that Lof-gren’s application for a patent was pending, approached Hampton whom they knew was Sanford’s supplier. Defendant’s officials testified they did so to get into production as fast as possible, and in order to “enjoy our share of the market as soon as possible.”

Hampton thereupon designed and produced Eberhard-Faber’s marker. Shortly thereafter the accused marker was introduced to the national market. ' Plaintiffs say “Thus the defendant was able to accomplish in ten weeks that which it could not by itself accomplish in ten years.” No claim is made that defendant’s marker does not infringe the patented device except for the trial court’s conclusion of law that defendant’s markers do not infringe “* * * since an invalid claim cannot be infringed.”

The application for the patent in suit had a rather rough trip through the Patent Office. All of the claims were finally rejected as unpatentable over the Rosenthal United States Patent No. 3,050,768 in view of the French Patent No. 1,063,019 to Williams et al.

The Rosenthal patent was removed from consideration by an affidavit by Lofgren filed pursuant to Patent Office Rule 131 to the effect that he had completed the invention prior to August 13, 1959, the filing date of the application on which the Rosenthal patent issued.

Attached to the affidavit were copies of photographs showing a number of test markers and certain of the test reports. These were received in evidence at the trial of the case.

Thus the Examiner had before him the information which Lofgren had *515 when he made his determination that the invention had been reduced to practice. In order for there to be a reduction to practice, there is no requirement that the device be then ready for commercial production. It is necessary only that the device be successfully tested.
