Do you know of any patent search tool that allows you to search text within a predetermined set of patents? preferably free tool.
Or alternatively, somewhere I can download the text of the set of patents I'm interested so that I can do local searches? Notice I have the pdf documents for these patents, downloaded from google patents, however these are scans with not too much quality -- and a local OCR doesn't seem to be able to get the correct text.
Expanding on Yorick's answer - I do not often recommend the USPTO search tools but this is a good use for them as long as you are not looking anything pre-1976. You can definitely download text using that URL at the USPTO and do a local search. Or a boolean search like [PN/(7,849,039 OR 7,890,523 OR 7,895,230 OR 7,933,904 OR 7,941,428 OR 7,970,822) AND locate] on the USPTO site (under Advanced) would look for "locate" in all of the listed "OR'd" patents and return a list of only the patents with that text.
. Note that to get published U.S. applications the search would need to be re-run. Patents and Publications are not searchable at one place.
Free boolean search tool, can refine search results:
Pattools is nice. I don't know if it has the exact features you are looking for, but it does allow you to give a list of patents. It returns the specifications and claims for those patents in a much nicer format than the PDF. It also allows you to download the PDF.
