Does it? As I said somewhere in another post, HP has just settled a case 
where a firm - Inkcycle -has had to pay up for selling refilled carts that 
infringed HP patents on ink. They had to alter the composition of the ink. 
They apparently didn't know HP had patents on ink!

Probably no problem for B&W inks unless they are copying patented 
carrier/solvent mixes or resin coatings.
