M-Systems Flash Disk Pioneers Ltd v Trek 2000 International Ltd & Anor [2008] EWHC 102 (Pat) (28 January 2008)

The patent application did not clearly and unambiguously disclose a portable data storage device without a cable; the claims as granted were not limited to cable-free devices and were anticipated by prior art; the proposed amendment would add matter and was inadmissible; no issue estoppel arose from the Singapore judgment; the Hearing Officer exercised discretion properly in refusing amendment.
