This not an approved patent, but the publication of a patent application. IIRC, applications are kept confidential for 6 months after filing. This might take 6 months to a year to be granted. LWLG is still provided protection for the invention.
I'm guessing that the enhanced chromophore described here is what the company was referring to in the Aug. 4, 2021, PR, where Lebby stated:
"Our in-house team successfully created a 2x improvement in r33, while allowing higher stability during poling and post-poling. This provides not only better thermal performance, but also enables greater design flexibility in high-volume silicon foundry PDK (process development kit) processes. This is critical as we seek to make our technology ubiquitous throughout the marketplace. Preliminary results suggest that Lightwave Logic's recently developed electro-optic polymer material, designed based on customer input, displays unrivaled thermal performance tolerance as compared to any commercial solution in use today. We look forward to receiving feedback on this exciting new material from our potential customers"
The application states "Nevertheless, the most daunting problem in the
production of commercially successful NLO polymers is the issue of resultant long-term material stability... Accordingly, there exists a need for improved nonlinear optically active materials having large hyperpolarizabilities and that when employed in electro-optic devices, exhibit large electro-optic coefficients and high thermal stability."
Lebby seems to be indicating that LWLG has solved the long-term stability problem, with the bonus of providing an increase of 2X in r33.
Also, this is not just an improved molecular structure, but also the "...methods of making nonlinear optical chromophores, their use in thin films and electro-optical devices containing such nonlinear optical chromophores and thin films comprising the same".
So, as they have done in other patents, LWLG is locking down the new molecular structure, how to make it, how to incorporate it into a polymer, and it's use in devices. Game, set, match.
