>TESS (the USPTO database search) sucks.
100% agree with you. A story I have told a few times on HN was getting a C&D letter for the use of the mark "blood" on a previous product I manufactured, and a basic search on TESS of "blood" will not turn up the registered mark (turns up a lot of other marks that include blood, but not blood by itself) I can only find it searching the registration number. Watsi is being classy by not even naming the company, but I would like to see the C&D or demand letter they received.
