Q: I believe the patent 'Display device based on phase-change materials WO 2015097468' is mine. Any no-win-no-fee services?

ABSTRACT

A display device comprises a plurality of pixels, each pixel having a portion (10) of a solid-state, phase-change material such as germanium-antimonium-telluride (GST) or vanadium dioxide, wherein the phase-change material can be reversibly brought into an amorphous state or a crystaline state and has a refractive index that is reversibly, electrically controllable. A plurality of electrodes (14, 16) are provided, at least two of which contact said portion of material (10). A controller (19) is provided that is adapted to apply at least one voltage to said material (10), via said electrodes (14, 16), to change said refractive index. An array of such portions of material can be arranged to make a pixellated display, for example a stereoscopic display of the volumetric type.

A: WO 2015097468 is not a patent. It is a published PCT application. There is a corresponding US application that was published as US20170031231A1 and has a priority date of December 12, 2013. Sometimes two people have the same good idea.

If they had the same idea that you had independent of any information from you and they filed a patent application, then their rights are going to prevail. If you can show that these folks had access to your idea before they filed the patent and it is your invention, then you can file to correct invention in the US. You will need to gather up the information that shows that you had possession of this idea before they filed the patent and some sort of path for them to access your information.

I do not handle litigation so I am not part of your solution.

Good Luck.
