The board (the ''Board'') of directors (the ''Directors'') of the Company is pleased to announce that important patents related to advanced and non-invasive detection technologies for cancer screening and monitoring owned by the Asian Advanced Medical Testing Center have been registered with the Patent Registry of the Intellectual Property Department of the Government of the Hong Kong Special Administrative Region. Details of the patents are set out below:

Patent Name:

A method for the direct isolation of peripheral blood

mononuclear cells enriched with circulating tumour cells for

use in liquid biopsy

Type:

Invention Patent

Patent Number:

30036746 A

- 1 -

Date of Application: 9 February 2021

Date of Expiry:

9 February 2029

The technology associated with this patent effectively isolates circulating tumour cells directly from peripheral blood for use in liquid biopsy, which simplifies the isolation process for enrichment of circulating tumour cells and improves the recovery efficiency of circulating tumour cells, thus solving the technical bottleneck of losing large numbers of circulating tumour cells with the existing technology.

Patent Name:

A multiplex immunofluorescence staining and bioimaging

method for circulating tumour cells for use in liquid biopsy

Type:

Invention Patent

Patent Number:

30036745 A

Date of Application:

9 February 2021

Date of Expiry:
