Pfizer Inc. was accused by a U.K. judge of making “groundless threats” of legal action against British doctors and drugstores if they prescribed or sold a generic version of its best-selling Lyrica treatment.

Judge Richard Arnold issued the rebuke as he ruled that Allergan Plc’s Actavis unit didn’t infringe Pfizer patents with its version of the drug pregalbin.
