PATENT INFRINGEMENTS HOLDING BACK
SALES OF COMPATIBLE CARTRIDGES
In
2007, the US International Trade Commission passed a ruling that fell to
the favor of Epson. This lawsuit claimed that 24 different makers and
manufacturers of compatible ink cartridges have infringed upon the
patent copyrights of the ink cartridges which Epson itself developed.
As a result of these rulings, a general exclusion, limited exclusion,
and cease and desist order were all placed against these companies.
These rulings mean that these companies cannot import their products
into the US, cannot sneak them in illegally, and that they will not be
able to sell the product which they already have here. This makes
things difficult for the compatible ink cartridge manufacturers.
There
are high standards placed upon any technology which is being developed
as a compatible ink cartridge. The design of the cartridge itself needs
to be different enough from the original to warrant it as new
technology, even if it is being produced as a compatible cartridge.
These are not standards which many compatible ink cartridge
manufacturers will strive to provide and as a result, they are now
suffering based upon these rulings. It may also be harder for you, as a
consumer, to find the cheaper products that you want for your printer.
Until
these compatible ink cartridge companies start to produce products
which are going to differ enough from the original patents filed, they
will not be able to sell their products within the United States.
Therefore, when you are looking to save, you will need to figure out
which compatible companies make products which are still legal.
