Did anyone RTFP? http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1%3Cbr%20%3E%3C/a%3E%20&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7,415,666.PN.&OS=PN/7,415%3Cbr%20/%3E%20,666&RS=PN/7,415,666 It looks to me that what is being claimed is one very specific formula for calculating *where to move to* in response to a page up or page down command. Hardly a generic patent on the concept of page up/down. Note how much detail is in claim 1. The normal process for predatory patents is to claim the moon, the sun, and the stars in claim 1, and then somewhere down around claim 10 get down to something narrow enough that it might survive a court challenge. This patent might be enforceable on claim 1 --- but by the same token it would be trivial to dodge. Just use a slightly different motion formula. regards, tom lane -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
