Your quote did not come from the PR therefore it has no validity. The PR said "Under the terms of the proposed agreement, the current holder of the worldwide rights, exclusive of Taiwan, Jessie Chiang, via entities she controls, will license to Plandai the exclusive rights to the Puriblood technology.
The reality is Puriblood and Formosa Plastics Group are the holders of the worldwide rights.
In doing a Google patent search https://patents.google.com/?assignee=puriblood the search indicates Formosa Plastics is patent co-assignee on almost every patent Puriblood received from the inventors (there were approximately five students listed as inventors for each patent. There was no mention of Jessie Chiang as a patent inventor or assignee.
Furthermore, the two companies describe themselves as strategic partners. Formosa Plastics has "invested hundreds of millions of funds to build a factory" and it will be ready by "2023".
