133 Mass. 443 | Mass. | 1882
This bill in equity is brought to enforce the specific performance of a written agreement, by which the defendant Entwistle agreed, as is alleged, for the consideration therein named, that any inventions which he might make relating to machinery built by the plaintiff, while he was in its employ, should be the property of the plaintiff; that he would assign all his interest in such inventions to the plaintiff, and do all acts necessary to make such assignment valid and effectual.

Such acts and declarations might perhaps tend to establish a subsequent oral contract, into whose terms might have been incorporated by reference those to be found in a previous written contract. No such oral contract was set forth or relied upon. The finding of the judge, upon this evidence, that the parties understood and treated the written contract as existing after the year had ended,
