Didn't you also write a MINSE-like filter to translate Chinese
characters into inline .gifs?

Not until you told us about it :)

The way worked was publicly known more than a year ago,
presumably more than a year before they applied for their patents.
Thus the way worked is not eligible for patenting. However,
you might have to get sued for patent infringement and prove this in
court to get the patent thrown out.

There's a service of the PTO called something like "invention
registration", which costs on the order of $20, which gets your
invention into the databases the examiners use when deciding if a
patent is unoriginal. This may be helpful in preventing the patents
from being issued.
