ValiRx Plc (LON:VAL) shares rose as it strengthened its worldwide patent protection for lead drug VAL 201 - having been granted a patent by the European office.
Chief operating officer Dr George Morris tells Proactive: ''It's always gratifying to have granted patents rather than just pending patents.''
''On this occasion I think it's particularly important in that all the key markets in which we are currently doing work and are likely to be doing work are now protected and covered for the use and the cancer therapy applications of VAL 201''.
