Carstedt v. Grindeland, 306 N.W.2d 105, 213 U.S.P.Q. (BNA) 706, 1981 Minn. LEXIS 1243 (Mich. 1981).

Opinion

TODD, Justice.

Howard Carstedt, a printing press mechanic, developed an apparatus known as a decurling bar which effectively increased the productivity of printing presses. Gordon Grindeland was engaged in the business of marketing a device he had developed for the printing industry. On hearing of Car-stedt’s device, Grindeland sought out Car-stedt. Carstedt filed a patent application and the parties entered into a licensing agreement. Grindeland began to market the decurler successfully and paid royalties to Carstedt. Thereafter, he was notified of a claimed prior patent and ceased paying royalties to Carstedt who then brought action under the licensing agreement. The trial court rescinded the licensing agreement on the grounds that Carstedt had committed fraud in failing to disclose prior use of the decurler bar at his place of employment for more than one year prior to the patent application, thus creating a public use of the decurler and rendering it unpatentable. We reverse.

Howard Carstedt is a printing press mechanic and general machinist. He was employed at Harrison and Smith Co., a printing company located in Minneapolis, Minnesota, for a period of 19 years, ending in 1978. He started out as a general maintenance man and eventually became a foreman. He had previously had 15 years’ experience as a printing press mechanic and was cognizant of problems encountered in the printing industry. One of these problems involved the curling of sheets after the ink had been applied, thus making it difficult to stack the sheets at the end of the run and necessitating the slowdown of the presses.

In 1965, Harrison and Smith had purchased a four color, 38-inch Miehle press. This press had a number of air bars which attempted to keep the sheets flat but were ineffective in preventing the curling of sheets. Carstedt conceived the idea of applying vacuum pressure to the sheets to remedy the curling problem. He obtained a piece of electrical conduit material and manually formed it into his first decurling device. He slit the tube and hammered the two sides down to form curved edges. An air line was attached and connected to a pump which produced a vacuum along the slitted groove between the two hammered, curved portions of the original tube. This device was installed on the Miehle press, *107 but its installation required the removal of a gas drying bar used in the printing operation.

There is dispute in the record as to the date of this first installation. The maintenance record kept by Harrison and Smith shows that the decurler bar was installed on January 8, 1969, which coincides with Car-stedt’s recollection of the time of the original installation. Other former employees of Harrison and Smith testified that they thought the installation had been made earlier. The trial court found that the first installation occurred in June of 1967, which is about the time Carstedt commenced employment with Harrison and Smith. However, we attach little significance to this dispute.

After the original installation, Carstedt observed continuing problems with his initial device. He attached an air bar above the device which improved its performance. However, the device could only be used in 20 percent of the press runs because of a variety of problems. Each time the device was to be used, the gas bar had to be removed. The slit provided an uneven vacuum supply and the crudely formed conduit caused problems. The bar itself was not straight, the edges were rough, and Car-stedt came to the conclusion that it could not be mounted close enough to the printed material. Nevertheless, Harrison and Smith continued to use this original device from time to time, and when it sold the Miehle press in 1977, the original device was included. Harrison and Smith never paid Carstedt for the use of the original decurler bar, and Carstedt testified that he was not satisfied with its performance and sought ways to improve upon his original idea. He also testified that he would not have been able to develop the device if he had been unable to install it upon a printing press.

Carstedt continued to watch the operation of his original device while at work. He also began experimenting with methods of improving his original concept. The evidence is uncontroverted that in the fall of 1972 he had constructed a new device consisting of two round copper tubes. Holes of even size and spacing were drilled to provide a uniform vacuum to the sheets. The tubes were straight which provided better contact with the sheets. The rounded edges provided a smoother surface. The tubes were then soldered together and provided a lower profile. This permitted a closer installation, and removal of the gas bar was no longer necessary. Vacuum was supplied by a separate pump and installation was simplified. Carstedt attached his two-tube device on a press at Harrison and Smith in the fall of 1972. He removed his newly developed two-tube device sometime in 1973. Carstedt was satisfied that his new device performed in a manner which obviated the problems that occurred in his original single-tube construction.

Gordon Grindeland has been associated with the printing industry since his youth. In 1955, he was employed by Harrison and Smith as a helper and feeder operator. He was familiar with the curling problem in the printing industry. In 1962, he left Harrison and Smith and worked for other printers until commencing his own business in the early 1970⅛. He had developed a mechanical method of removing “hickey spots” from printing press plates. He obtained a patent on this device with the help of the Dorsey law firm in Minneapolis. He was marketing his device as a sole proprietor under the trade name Clean Print Systems, Inc. In the fall of 1972, he was advised by an employee of Harrison and Smith that Carstedt had developed a decurling device. In November or December of 1972, he contacted Carstedt and invited him to his home to discuss his decurling device, Carstedt and his wife came to Grindeland’s home in early January 1973. Carstedt brought with him the full length, two-tube curling device he had assembled and had run tests on in the fall of 1972. The parties are in disagreement as to whether or not there was a discussion of the single-tube prototype device originally developed by Carstedt.

As a result of this meeting, Grindeland arranged for the parties to meet at the Dorsey law firm on February 5, 1973, to consult with Eugene Johnson. Prior to the *108 meeting, Grindeland prepared a pencil sketch of the two-tube decurler based on information supplied by Carstedt. Carstedt brought with him to Johnson’s office a model of his two-tube decurler. Carstedt testified that he had never been involved in a patent application prior to the February 5, 1973, meeting. Understandably, Johnson testified that he could not clearly recall the discussions at the meeting. He received the sketch prepared by Grindeland, made further notes thereon, and had the document executed by Carstedt and witnessed by himself and Grindeland. Johnson acknowledged that Carstedt had brought with him a model of a two-tube decurler. He further testified that he knew Carstedt had never been involved in a patent application. Johnson testified that it was his practice to make inquiry as to prior use of the invention and he had followed this practice on February 5. He stated that it was his impression that the device had been in use about two months.
