And why does POET continue to maintain the POET GaAs patents. I recall Suresh talking about how expensive it was to continue maintaining these patents (filing fees) and that the plan was to maintain only the seminal patents. But we know from the latest presentation that the GaAs patent portfolio which is very large is still owned by POET.

There are some wickedly inventive approaches on a multitude of applications in that portfolio.  

Interesting links that you point out ITTR.

Will POET have another Eureka moment as it becomes a leader in the global photonics industry? I believe there will be many. Suresh is a young man and I think he is just getting started.
