Yes definitely worth holding,

FGR are already talking with potential industry partners for the commercialisation of FireStop, source found here

FGR have many more developments that are soon to be announced,

Conductive inks - thanks to the ARC Graphene Hub research,
Concrete strength improvement by using Graphene oxide and reduced graphene oxide - if I have the right research paper by the University of Adelaide the results exceed Talga's and Eden Innovations EDE's MC is nearly $200mil.
They are also working on graphene supercapacitor - Cobalt / Lithium free. they recently received $1.5 Mil in Government funding to further develop / commercial the BEST battery and the VFD device.
A multi purpose graphene composite (paint), the coating according to the IP has a 96.78% corrosion resistance, It is self cleaning, anti bacteria and scratch resistance. Here is a link to the IP
