At least one of the patents was for an automated way to search for an image in an online database by bib number. Now unless someone can show that they had such a system prior to that then he will win his case.
I look up my very obscure perverted Japanese fetish pron using an online search and the catalog number. Cuts down on false hits 100%, no keywords that would cause lots of headache and likely viruses (virii?)
can I patent that?
