Union Paper Collar Co. v. Van Dusen, 90 U.S. 530, 1874 WL 17491, 23 L.Ed. 128, 23 Wall. 530

Facts

The Union Paper-collar Company filed a lawsuit against Van Dusen to prevent him from making shirt-collars from a specific type of paper, claiming an exclusive right based on patents reissued to Andrew Evans and Solomon Gray. Van Dusen admitted to using both the paper and the device for turning the collars but contended that the patents were invalid due to lack of novelty and that the reissue was not for the same invention as the original patent. The case revolved around the validity of these patents and whether the claimed inventions were indeed novel.

Issue

Are the reissued patents for the fabric and device used in making shirt-collars valid, or do they lack novelty?

Are the reissued patents for the fabric and device used in making shirt-collars valid, or do they lack novelty?

Rule

A patent can only be issued for a new and useful invention that is not known or used by others. A reissued patent must secure the same invention as the original patent, and parol testimony is inadmissible to expand the scope of the invention beyond what was originally described. The determination of whether a reissued patent is for the same invention as the original depends on the specifications and drawings of both patents.

The purpose of a reissue is to render effectual the actual invention for which the original patent should have been granted, not to introduce new features.

Analysis

In this case, the court analyzed whether the reissued patents for the shirt-collars were indeed for the same inventions as the originals. The court found that the reissued patent described a different type of paper than that specified in the original patent, thus constituting a different invention. Additionally, the evidence showed that the collars made from the new paper were not novel as they were similar to previously known collars made from other materials. Therefore, the court concluded that the patents were invalid.

Conclusion

The court held that both the reissued patents for the fabric and the device were invalid due to lack of novelty and because they did not represent the same invention as the original patents.

Who won?

The Union Paper-collar Company prevailed in this case as the court ruled that the patents held by Van Dusen were invalid. The court's reasoning was based on the determination that the reissued patents did not secure the same invention as the original patents and that the claimed inventions lacked novelty, as they were not new in the commercial sense and had been previously used in the industry.
