Amazon Patents Counting Book Pages To Figure Out Unnumbered Page Numbers

from the doing-the-math dept

theodop writes "The USPTO has issued Amazon a brand spanking new patent for Determining Page Numbers of Page Images, a process which the e-tailer explains involves 'extracting all numbers that are exactly one different than a number found on an adjacent page'." Basically, they've figured out a way to look at pages in a book and see if some of the pages don't have numbers, and then use basic addition and subtraction to figure out what the actual number of those pages are. This isn't particularly complicated. Why should one company get a patent for it?

    I don't think this is quite as simple as you're making it out to be. It seems to me that the patent covers using OCR on a scanned page. Then it extracts ALL of the numbers on the page (which is usually just the page number, but not necessarily; consider a math book) and tries to determine which are the page numbers. It takes into account that some pages might not have numbers on them, but the patent isn't JUST that.

    I'm not necessarily saying it's not obvious, but it's not as obvious as you're making it out to be
