Draft IPO prospectuses full of "bombastic language" are causing headaches for the lawyers who edit them, with food producers promising "high quality" smiles with each bite and real estate companies masquerading as technology firms.

It has been a busy year in Europe's IPO markets, with 225 floats worth $64.5 billion so far this year, according to Dealogic, compared with 118 worth $23.1 billion in 2013. This increased competition for investors' money has been reflected in the use of marketing spiel in draft prospectuses, according to capital markets lawyers.
