RE:TLD 1433 Patent expiry July, 2034 Always been a concern that getting FDA approval would take too long and reduce the value of an acquisition due to the limited patent time remaining.
Part of the process is the laser device. Will TLT or its successor company owns the laser? If so the generic drug manufacturer would need their own approved laser and that might be a deterrent.
I would look at the newest PDT drug that Theralase will use for brain and lung cancer, run clinical trials and get it approved for bladder cancer. I would expect further improvement in the results achieved.
If successful it would reset the patent protection. By the time TLT or it's successor company would need to run the trials money should not be an issue.
