Patent could be "sub-licensed" by TCEL to someone else depending on the type of license originally granted to TCEL. Of course, we don't know for sure. Patent licenses are wonderful in that there is some flexibility depending on the wishes of both parties.

"Exclusive license: Under an exclusive license, a patent owner transfers all indicia of ownership to the licensee only retaining the title to the patent. From the point of view of the patent owner, he surrenders all rights under the patent (including the right to sue for infringement and the right to license) to the licensee. In essence, the licensee steps into the shoes of the patent owner and acquires the right to sub-license the patent and sue for patent infringement. However, the exclusivity can be limited by a field of use. That means that the licensee gets a promise from the patent owner that the patent will not be licensed to anyone else in a stipulated field of use."
