    Inventor David Parsons sues Convatec for up to £366m over Aquacel patent profits

    Lawsuit filed

    Analytical chemist Dr David Parsons, who worked for FTSE100-listed Convatec Ltd from 1991 until 2023, is suing the medical products company at the UK High Court for compensation of up to £366m under Section 40 of the Patents Act 1977, claiming that patents bearing his name - used in ConvaTec's Aquacel antimicrobial wound dressings - created an 'outstanding' benefit for his employer. Convatec is fighting the claim, arguing compensation is due only for exceptional individual inventions rather than patents considered collectively; the case reached the Court of Appeal this week over the issues to be determined, judgment is likely to be reserved, and a six-week High Court trial is set for 2028.

    Stated objective. Dr Parsons is suing for compensation of up to £366m, demanding a share of the profits, on the basis that his patented inventions created an 'outstanding' benefit for ConvaTec.

    Criticism over continued Russian-market activity

    ConvaTec was included in the Leave Russia project, which tracks companies that continued operating in Russia. Critics argued that continued sales activity indirectly supported the Russian economy and government during the war in Ukraine. The company had suspended its Russian sales team and closed its Belarus manufacturing facility in 2022, but criticism continued over its broader Russian presence.
