Brazen, I believe you misread my post. I was one of the posters taking the position that only the artisanal manual process was included in the DCvax L application and the mention of the Flaxworks process in the company's business plan around the same time should not be interpreted as adding a second

I kinda wish for a merger now with IBATF + EnergyX at this point, if no contract happens soon with T5 or Exxon. That merger could combine X’s membrane tech, IBAT’s modular DLE and proprietary media, ready to deploy now on existing X Smackover resource, and X builds their Lonestar refinement plant…fa

I remember when they were not responding to the lawsuit, I posted saying they were making a mistake and how this could be really damaging.
