In patent law, making sure that all the correct inventors are named in a patent application is critical to the validity of the patent. If an inventor is incorrectly included, or if an inventor is omitted from the list of named inventors, it can result in a patent being found invalid and thus unenforceable.
This happened recently to Fortress Iron, LP (“Fortress”). This week, the U.S. Court of Appeals for the Federal Circuit ruled against Fortress in Fortress Iron, LP v. Digger Specialties, Inc.,. The case involved a couple of issued patents directed to a vertical railing panel that could be purchased as a pre-assembled panel. The idea was initially developed in 2013 by two Fortress employees in the U.S. However, the initial design had issues relating to rotation of the panel during tensioning of the cables. Fortress works with two Chinese companies, a manufacturing company and a quality control company to produce its products. An employee from the manufacturing company and an employee for the quality control company worked with Fortress to revise the railing panel design to alleviate the rotation during tensioning.
After a final design was completed, Fortress applied and obtained two patents for its vertical railing panel. Both Fortress employees were named as inventors but neither the manufacturing company employee nor the quality control company employee were named as inventors. In 2016, the quality control employee involved in the design of the railing panel left his employment and did not provide a forwarding address.
In 2021, Fortress sued Digger Specialties Inc. (“Digger”) for patent infringement of the two patents directed to the vertical railing panel. During the lawsuit, it was discovered that the two Chinese employees were omitted from the patents when they should have been included. Moreover, Fortress could not amend the patent to include the quality control employee because he left no forwarding address after his employment and could not be found.
The appeals court ruled that because Fortress was not able to name him as an inventor, the patents were invalid. Fortress was unable to assert its infringement claim against Digger because the patents were no longer valid and thus unenforceable.
What’s the takeaway here? Patent inventorship is an important consideration when filing for a patent. Inventorship is defined as a person who has contributed to the conception of the invention. Conception has been described as someone who has a definite idea of the complete invention. Because the claims of a patent define the invention, an inventor is anyone who has contributed to the conception of at least one claim in the patent. Failure to include an inventor or including a non-inventor can jeopardize the validity of your issued patent.
