north40000, I am not sure PPHM can file further patents for that.

Now, has anyone seen a pending patent application, published, for the kit comprising the exosome process in a manufactured form for detecting and diagnosing multiple solid, maybe even blood, cancers and tumours? SK said such kits are nearly ready and completed, stay tuned for further updates.

Why do I think that? Liquid biopsy is not new. Liquid citometry isn't either. The manufacturers of related equipment (mostly very large companies) are mostly owner of their form factor (most certainly protected by a design patent) related to the presentation/interface of a test kit to their equipment. And they are CERTAINLY owner of their separation and queuing techniques used inside those equipment because that is their differentiation/unique selling proposition.

So PPHM relies on the A Schroit patent for the technology that the kit will use and that should suffice because it is that technology that achieves the results related to EARLY CANCER DETECTION based on PS-bound exosomes and hence no one may place that technology (that would match that patents claims) in ANY form factor.

So unless PPHM (or UTSW) added something else that increased the accuracy or improved to application of the patented technology in any other way, then I don't see what other patent we could expect.

The loop-hole may be in tuning % of measurement towards results (but I am sure that any contract with UTSW would mention THEY must be part of the patent if based on an improvement on theirs). An example would be that PPHM by its test on humans detect that the false negatives in ovarian cancer came from a woman that had breast cancer and that this masked the detection of ovarian and that NOW PPHM made corrections to the kit to overcome that with a new technique that they think is sufficiently uncircumventable to patent it because it is crucial to obtain the same quality of test.
