how to search in patents

i need to know how can i search for an IC in the patents regarding that all i know about it is its part number and the name of manefacture .

use technology

The part number does not appear in patents. You will have to use general terms for what it does.

I use www.delphion.com and uspto.gov. Seach by Assignee (for example Analog Devices).

www.delphion.com

Requires registration and it is not free . :evil:

hello,

i think it is right that delphion is not for free, but in "http://patents.uspto.gov/" you can search for us patents and get good results. another search engine is "http://ep.espacenet.com/" for european patents (i'm not sure but i think here you will get world wide patents).

try this two pages. in the beginning it is a little bit tricky, but in the end there are useful results.

greetings,
