Russell v. Place
Facts
The complainant alleged infringement of a patent for an improvement in the preparation of leather and sought an accounting of profits and an injunction. The defendants admitted the patent, its surrender, and reissue, but defended on the grounds of want of novelty, prior public use for more than two years, and lack of identity between the original patent and the reissue. The complainant had earlier recovered a judgment for damages against the same defendants in a patent action at law, where the defendants had pleaded the general issue and specially noticed want of novelty and prior public use. But the record of that prior action did not show which of the patent's two claims formed the basis of the verdict, and no extrinsic evidence was offered to clarify the point.
Issue
Whether the prior judgment for patent infringement damages estopped the defendants in this later suit from contesting novelty, prior public use, infringement, and the validity of the reissue. More specifically, the question was whether the former record sufficiently showed that those precise issues were actually and necessarily determined.
Rule
A judgment of a court of competent jurisdiction is conclusive in a later suit between the same parties only as to a question directly involved and determined in the earlier suit. To have that effect, it must appear from the face of the record, or by extrinsic evidence consistent with the record, that the precise matter sought to be concluded was actually raised and necessarily decided; if the record leaves it uncertain because several distinct matters may have supported the judgment, there is no estoppel unless the uncertainty is removed by such extrinsic evidence.
