Text: 38 16. The application for patent was filed September 17, 1962, by E. D. Nystrand, J. J. Bradley, and H. J. Spencer. Nystrand is deceased but Bradley, his successor as vice president in charge of engineering for plaintiff, testified at the trial, and I was very impressed with his testimony. The examination of the application in the Patent Office resulted in the allowance immediately of 16 of the 21 claims presented, the remaining claims being modified thereafter and the patent issued as No. 3,179,348 on April 20, 1965, with twenty claims. On September 1, 1972, an application was filed to reissue the No. 3,179,348 patent because: 39     At the time of filing the application and during the prosecution thereof they (the inventors did not know of the existence of Christman Patent 2,585,226 which shows means for transversely severing said web to provide a free leading edge on said web for approaching a mandrel on which said web is to be wound in said path, and means for maintaining a web portion spaced from said edge in contact with said roll. The Christman patent was first brought to their attention on or about June 8, 1972 by the attorney who was handling the prosecution of the corresponding application in Germany, where the said Christman patent was cited as a reference. As a result of the study of the aforesaid Christman patent, it was determined that certain of the claims in the original patent were too broad, and, accordingly, an application for reissue with narrowed claims is sought. 40 The above error arose through error and without any deceptive intention on their part. (From the Oath in the File Wrapper for Patent Reissue No. 28,353; see trial Exhibit No. 509.) 41 By the reissue claims 1 and 2 were modified, claim 3 was cancelled, and the patent issued as Patent Reissue No. 28,353 on March 4, 1975. Reissue Patent No. 28,353 has the same term as the original patent, expiring April 20, 1982.
