1Opinion of the Court
LEAHY, Chief Judge.
This is an action for judgment that defendants’ pooled patents be declared unenforceable against plaintiff. Defendants counterclaimed charging infringement on specific patents. In 1946 plaintiff was a licensee under defendants’ patents. Plaintiff brought its first declaratory judgment suit and this particular action came at issue. Then, after the license had expired plaintiff brought its second and the present suit. A statement is made that a motion will come later to consolidate. 1 The second complaint, substantially similar to the first, recites that the license has ended.
