Case Summary

This case, Janich v. Collins, involved a dispute over the ownership of a patent for a 'Quick-Change' barrel assembly for firearms. The plaintiff, Janich, claimed that he was the sole inventor and that the patent should be issued to him. The defendant, Collins, argued that he was a co-inventor and that the patent application correctly listed both of them. The court ultimately sided with Collins, finding that Janich failed to provide clear and convincing evidence that he was the sole inventor. The evidence showed that Collins contributed significantly to the conception of the invention, particularly regarding the critical 'quick-change' mechanism, and that Janich himself had previously acknowledged Collins's role as a co-inventor in earlier patent applications and communications. The court affirmed the lower board's decision, concluding that Janich did not meet the high burden of proof required to change inventorship on an issued patent.

Key Holdings

The court established the following key holdings in this case:

  1. To change inventorship on an issued patent, the party seeking the change must prove sole inventorship by clear and convincing evidence.
  2. Conception of an invention requires the formation in the mind of the inventor of a definite and permanent idea of the complete and operative invention, as it is thereafter to be applied in practice.
  3. A person is a joint inventor if they contribute to the conception of the invention, even if their contribution is not to every claim of the patent.
