This case was in the OCF news feed last year
J&J lawsuit: listerine I've seen nothing else in the news, but this web site has links to keep you updated. Justia court filings According to it, the lawsuit was stayed and the matter removed to arbitration.
The entire court order is here
J&J suit out of court into arbitration
There is no active court case since the judge's ordered the clerk to terminate the case without prejudice which means it could be reopened
My reading of the pleadings is that the issue of whether or not Listerine can cause oral cancer will not be any part of the litigation but rather the failure to sell OCP's products.
In lawyer talk, its not relevant nor material whether or not Listerine with alcohol causes oral cancer, the issue is whether or not J&J violated its contractual obligations.
it is interesting tho that J&J launched its alcohol free Listerine at that same time.
I feel for you as I believe my daily use (3x a day) of Listerine was a contributing factor although HPV was the primary one. Yet this dismissed lawsuit will not address that issue.
