M-Systems Flash Disk Pioneers Ltd v Trek 2000 International Ltd & Anor

M-Systems Flash Disk Pioneers Ltd v Trek 2000 International Ltd & Anor

The patent application did not clearly and unambiguously disclose a portable data storage device integral with no cable; neither granted nor proposed amended claims were limited to such devices. Amendments to claims would add matter not disclosed in the application. The Singapore Court of Appeal decision did not create an enforceable issue estoppel in this jurisdiction. Trek failed to provide sufficient information for the exercise of discretion to amend. The appeal is dismissed.
